Abstract: The modern-day town of Port Royal, Jamaica, bears little evidence of its spectacular past. In Port Royal Jamaica, Pawson and Buisseret detail the establishment of the town of Port Royal in the second half of the seventeenth century, in the heyday of privateering. The town was critical to the successful colonization of Jamaica by the British and pivotal to British mercantile activity, but is best known for the activities of its swashbuckling pirates.

Abstract: Abstract Experience gained from a recent evaluation of smoking machines has been applied in the design of a sophisticated automatic smoking machine. Utilizing a reverse puff mechanism, a continuous or intermittent smoke stream is generated, diluted to selected concentration levels and channelled to multiple exposure apparatus. AlI functions are completely controlled by digital electronics as is the detection of faults in the system. Analysis of the smoke produced indicates that it is not chemically different from the smoke delivered by other types of apparatus

Abstract: A trailer air distribution valve has a housing, a chamber in the housing and an air inlet port, an exhaust port, at least one service tank port, an emergency tank port and at least one brake chamber port, all in communication with the chamber. A shuttle is movable within the chamber to control communication between the ports and includes a pair of spring biased valves functioning as check valves to control communication between the inlet port and service tank port and the emergency tank port.

Abstract: A link is connected between each linefinder/first selector combination of a telephone system. The links, in turn, are selectively connected to a group of ports, several links to one port, and the ports are connected to one or more telephone signal processors. When a telephone goes OFF HOOK, the sleeve or C lead of the linefinder at which that telephone's scanning switch is then pointing (determined by the associated link being connected to an available port) is grounded. When the address of this link next occurs in a time multiplex cycle, the link is latched, and the telephone's tip and ring leads are connected to the link's port. After signal processing has ended, or some other release action occurs, the port generates a release signal that disconnects the link from the port. While any link is connected to its associated port, a make-busy ground circuit forming part of eack link applies a false busy signal to the linefinders associated with the other links common to the same port. The false busy signals prevent the linefinders associated with the other links from attempting to seize the busy port via those links. Termination of a conversation flowing through one link creates a WINK signal that causes a release of its associated linefinder, even though another link may be connected to the associated port at the time the conversation is terminated. In the case where two links associated with the same port attempt to seize that port at substantially the same time, the link having the earlier address in the time multiplex cycle actually seizes the port. The second link, upon sensing the creation of a false busy signal (causes by the seizing of the port by the first link) is dumped. Dumping the second link causes the dumped link's linefinder scanning switch to route the second call to a linefinder having a link whose associated port is available for signal processing.

Abstract: THE influence of the Christian missions in Papua New Guinea dates from the year 1872, when the Catholic Mission of the Sacred Heart commenced its activities in New Ireland. The same year the London Missionary Society, representing the British Congregational Church, arrived in New Guinea, and two years later their missionary, Lawes, established himself in Port Moresby. By the end of that decade two other Protestant missions, the Methodists" and the Anglicans, had made their claims in Papua.

Abstract: This article describes the use of the Variable Incident Simulation Apparatus, which can provide trainees with useful experience in port management within the confines of the laboratory. The equipment is capable of determining the effects of various delays on port operations, and alternative policies can be tested. A single delay factor may be used in the simulation in order to highlight its individual effect on the overall operation. Various system equipment is described, and the design of the simulation model is also discussed. The author believes that while this exercise does not simulate perfectly the total port system, nevertheless it is a valuable tool for port management training purposes.
