Abstract: A group of fluid input connectors and a group of fluid output connectors are coupled together to provide a matrix of paired, aligned ports, one port of each pair communicating with one of the input connectors and the other port of the pair communicating with one of the output connectors. Programming means couples together the individual respective ports of preselected pairs, and isolates from each other the individual respective ports of the remaining pairs.

Abstract: A unitary pneumatic flow director comprising a casing with a plurality of inlet ports and an outlet port. The casing interior is a reference chamber which communicates between the inlet ports and outlet port. A pressure responsive valve is concentrically aligned with each inlet port. The valves control the normal flow of fluid through their respective inlet ports into the reference chamber in response to external pressures exerted at the mouth of thier inlet ports and provide a restricted reverse flow of fluid which may act as a scouring stream for the inoperative section of a cyclic fluid system.

Abstract: Growing up successfully involves the selection and acquisition of a satisfactory set of values from among available alternatives. The central problem for those growing up at this time is the rapid transformation our values have been undergoing-a circumstance which denies them an explicit and stable set of values from which to choose and with which to identify.' The famous Port Huron Statement adopted by the Students for a Democratic Society in 1962-a statement whose relevance was so underestimated at the time-found its passionate appeal among students precisely because it focused on this problem of values. It posed the issue directly: \"Making values explicit-an initial task in establishing alternatives-is an activity that has been devalued and corrupted. The conventional moral terms of the age, the political moralities . .. reflect moralities poorly, if at all, and seem to function more as ruling myths than as descriptive principles. . . . The questions we might want raised-what is really important? can we live in a different and better way? ... are not thought to be questions of a 'fruitful, empirical nature,' and thus are brushed aside.\"2

Abstract: Overall costs of £20,000 a day for operating the very largest tankers make it important to extend the period between drydockings as much as possible, to keep the time spent in port to a minimum, and to avoid even small losses of speed in service.

Abstract: An example of port expansion is studied with the assistance of queuing theory and the analysis shows that duplication of a capital intensive bulk loading installation is not justified until relatively high berth occupancy figures of approximately seventy percent are achieved.

Abstract: The study is an evaluation of the environmental impact of a deep-sea port off the Texas coast Both the non-spill impact of construction and operation of the port and the potential oil spill impact on the coastal environment are considered The scope is limited to two terminal locations, three designs of port facilities, and three sizes of oil spills Also considered is the environmental impact of not constructing the port but expanding the present methods to meet the oil import needs of the area The major physical, bioligical and cultural features of the Texas Coastal Zone that might be impacted by the supertanker activity were inventoried Models were developed to predict where oil from potential offshore oil spills would go and which environmental features would be affected

Abstract: A drain port valve especially adapted for use with plastic bags or vessels which may be utilized for containing and transporting liquids.

Abstract: The report was compiled to aid in selecting suitable supertanker terminal sites for the United States. It presents climatological criteria necessary to assess the environmental effects on supertankers at selected Gulf and East Coast ports. A general description of the major environmental controls governing the study area is followed by detailed analytical summaries for each port.

Abstract: Summary In September 1968, one of the authors (P. Mayes), having been appointed Head of Mission by the British Ministry of Overseas Development to act as advisor to the Jamaica National Trust Commission, made recommendations which formed the basis for the establishment of the Port Royal Project. The Project is concerned with the excavation, conservation and presentation of 17th century Port Royal, which was founded in 1655 and destroyed by an earthquake in 1692 (see Fig. 1). For the purposes of archaeology the area was divided into three: the Archaeological-Historical Reserve, encompassing the protected underwater area and lands currently occupied by government facilities at the west end of Port Royal; the area in the centre of Port Royal which is protected archaeologically by modern housing and the area at the east end of Port Royal in which it was proposed that commercial expansion should be allowed on land held on lease from the Jamaican government. Work began early in 1969 in a section of this last area, which was threatened, at that time, by the construction of an hotel. This area was part of the shoal water section of sunken Port Royal (see below and Fig. 2). Since that date excavation headquarters and conservation laboratories have been established in the old naval hospital and the construction of a major museum, the first phase of the presentation programme, has begun.

Abstract: THE COASTAL LOWLANDS of southeastern Papua are subject to a monsoonal climate. Semideciduous scrub and forest, and eucalypt savannah are characteristic elements of the vegetation (Heyligers, 1965, 1966). During an investigation to determine whether the savannah is a climax vegetation or a disclimax caused and maintained by man and fire, I analyzed the geographical affinities of the species in these vegetation types to elucidate some aspects of their autecology and of the history of the area. Most of the literature on plant geography of neighboring areas, however, deals wholly or mainly with genera and, therefore, the distribution of the genera has been analyzed also. This lead to the discovery that in the Indo-Malesian Floristic Region the relationship between number of widespread genera and total number of genera could be expressed by a single logarithmIC senes.

Abstract: This paper attempts to illustrate through the case of the Clyde an evolution common to general cargo ports situated at the head of estuaries. Until 1969 trends in the traffic of the West of Scotland ports had shown a marked decline and the need to discover its causes has led to the investigation of the ports’ capacity and performance. Several approaches for assessing efficiency have demonstrated the inadequacies and the under‐utilization of facilities dating from the 19th century, especially in the Upper Reaches. The need to speed up transhipment and make the ports efficient in the different conditions of the 20th century has brought about some changes in the location pattern of their activities. Alterations in the ports’ lay out and the diversion of cargo from up‐river berths have been the main geographical consequences of the effort of rationalisation and modernisation.

Abstract: This study is dedicated to the proposition that there has been considerable cart-before-horse-putting in the port analysis business. Rather, analysis has concentrated on the development of highly detailed simulation models for revealing the effect of specific individual investments or operating alternatives on the port's day-to-day operating characteristics. The question of whether the resulting change is consistent with the port's overall objective is generally not addressed or considered only in the context of the port's present pricing policies. This concentration on a variety of subproblems while ducking a basic issue is in part a consequence of the fact that ports almost never make explicit their objective. Indeed, for the most part they are almost certainly unaware of the possibility and value of so doing. One objective of this study is to demonstrate the kind of insight which can be obtained from postulating an explicit objective function. Analysts have not given port managers the insight into their pricing and expansion decisions--and the coupling between these decisions--that the importance of these decisions deserves. This paper is an attempt to develop this insight and exhibit this coupling in the context of a simple model of port development. Three by-products of this analysis in order of increasing importance are: 1) An introduction to dynamic programming for port investment. 2) Demonstration of how the port manager can analyze his decisions without resorting to direct evaluation of benefits which accrue to economic entities outside the port. That is, why can't I figure out what I should do like any other business? 3) Demonstration that, uncertainties aside, not only does marginal cost pricing not necessarily lead to deficits but that, coupled with an efficient expansion policy, it necessarily implies that each investment will just pay for itself over its life.

Abstract: In this paper, which was presented at an Institute meeting held in London on 26 May 1971, Captain Brandenburg discusses the problems of port and terminal navigation control in the 1980s and takes up the questions whether such control will be needed and how much control will be appropriate.This paper is not concerned particularly with problems in Rotterdam, or indeed with any particular ports, but rather with an overall evaluation of probable port developments in the near future, say the 1980s, and with the steps which may be necessary to meet the problems that will arise. In speaking of port and terminal navigation one should distinguish between pilotage, which may be defined as conducting a ship in safety from one manœuvring area to the next, and manœuvre, which is the handling of a ship in confined areas with whatever aids are available. It is well known that the danger and difficulty of manœuvre varies greatly in different areas and this was the subject of an analysis by Captain Wepster, but I shall consider manœuvres common to all terminal areas:(i) picking up the pilot and lining up into the fairway channel,(ii) docking and undocking,(iii) lining up into the fairway channel again,(iv) dropping the pilot and heading up for destination.

Abstract: Every port has an inland area tributary to it, a cargo shed area, on which it depends for its shipping market. The identification of this “natural” hinterland of a port, or of a range of ports, is of considerable interest to port authorities, port service companies, transportation companies, and regulatory and policy‐making government agencies. A hinterland can be thought of as a cargo shed area in at least two senses: as comprising the domestic origins and destinations of cargoes presently moving through the port, and as the inland area in which the port has a favourable economic position as a trans‐shipper of imports and exports. The two areas so defined certainly have a substantial overlap, but they do not necessarily coincide.
