Abstract: A distributed packet switching system in which each transmitting port (101) contains the intelligence required to derive and then insert the destination port and station addresses into the header of each packet to be transmitted by the port. The port circuitry that derives the destination addresses operates under control of a central controller (107) which, prior to the setup of each call, receives the address of the transmitting port as well as the destination station number dialed at the calling station. The controller processes this data to derive the destination port and station addresses. The derived addresses are stored in a RAM (309) in the transmitting port. The RAM outputs the destination port and station addresses for the first byte of each packet subsequently transmitted by the port on the call.

Abstract: A valve is disclosed suitable for use in ink marking systems. The valve has an output port, a supply port, and a control port. The control port communicates with a chamber disposed above a flexible diaphragm while the output port communicates with a reservoir to be periodically supplied with fluid. The diaphragm flexes between an open position permitting the supply port to communicate with the output port and a closed position blocking such communication as a function of the pressure differential across the diaphragm created by pressure changes at the central port.

Abstract: Wharf facilities which are constructed and administered by public authorities of seaports are regarded as social overhead capital. Since the services that they furnish are not brought to the market, the optimum distribution of services from the viewpoint of social benefits is difficult to quantify. Specifically, ships arriving at a port inevitably bring about external diseconomies resulting from congestion in a port. Evidently, it is important to decrease or eliminate such external diseconomies. In this study, a port with public wharfs which handles general cargoes is treated; and the congestion at a port is analyzed both from economic and engineering points of view. Furthermore, preliminary examinations are made of the method for determining the optimum degree of usage of the wharf facilities, and the method for realizing the optimum degree by means of an adequate pricing system.

Abstract: A tunnel-type boat hull construction is operative with substantially reduced frictional resistance in the water and also with improved high-speed stability. An air-withdrawal port is provided in the now portion of the tunnel, and exit ports which are interconnected to the withdrawal port are provided along generally downardly facing submerged surfaces of the hull. When the boat hull is operated in a forward direction, air is captured in the forward portion of the tunnel, and a portion of the air is withdrawn through the withdrawal port and is exited through the exit ports. The air which is exited through the exit ports provides lubrication for the submerged hull surfaces so that the hull is operative with substantially improved efficiency; and because the air is withdrawn from the bow portion of the tunnel, the bow uplift effects which are characteristic of conventional tunnel-hull-type vessels when they have been operated under high-speed conditions are substantailly reduced.

Abstract: Port commodity specialization is primarily influenced by economic functions, but also by unique geographic considerations. A port system's evolution is dependent upon a complex mix of both physical and human factors. A case study of Chilean ports examines their potential for increasing containerized traffic. By applying indices of port commodity specialization and national commodity specialization to maritime transport data, a series of working hypotheses pertinent to specialization is tested. Suggestions are made for developing a port system to accommodate containerization. The results indicate that Chile should support the development of three regional port subsystems.

Abstract: TAILORED DOCUMENT BUILDING Abstract A method of, and system for, tailoring a master document to obtain a special document. The master document is made up of data objects and portions of the data objects. Included in the portions are pointers to corresponding data objects. The portions are windowed and displayed. Selection of a window will result in a view port being opened through the window into a corresponding data object. The data object can then be scrolled to obtain a desired portion to be included in the special document. As each desired portion is obtained, it is stored and becomes part of the special document.

Abstract: A competitive power extraction problem is defined where the power at each load connected to a linear n -port is to be maximized. Complete solutions to the resistive two-port and reactive two-port cases are presented. Some preliminary results for the resistive n -port case are indicated.

Abstract: Port authorities perceive their ideas as broadly supportive of regional economic development and are strongly associated with chambers of commerce, economic development agencies and growth oriented citizens groups. However, shifts in American foreign trade and the use of new technologies atid environmental regulation have dramatically changed the seaport industry over the last 15 years. As public enterprises, many ports responded to the new competitive markets by developing efficient but capital intensive container technologies. Environmental regulation also had a role in stimulating more efficient use of port lands. Although frequently viewed as a road block to all development plans, the intergovernmental review processes may have helped turn ports away from their traditional patterns of land expansion development and toward redevelopment of existing facilities. With the constraint of greatly reduced expansion opportunities. the enterprising ports figured out they could greatly increase cargo handling capacity without enacting the wrath of environmental quality interests. This paper examines this contention with both economic logic and inferential data.

Abstract: PURPOSE:To improve volumetric efficiency of a cylinder for supercharge through utilization of a phenomenon of direct blow from an intake port to an exhaust port by forming the bottom of a cylinder head in a recession. CONSTITUTION:An intake port 13 and an exhaust port 14 are respectively positioned, in a plane view of an engine 1, on both the left and the right sides with respect to the longitudinal center line of the engine. On the other hand, in a part where the intake port 13 and the exhaust port 14 open into a cylinder chamber, a partition wall part 36 partitioning said ports 13 and 14 forms a recession as much as a dimension H from the bottom 19 of a cylinder head, to the side reverse to the cylinder chamber. This reduces turnabout of air when it flows out of the exhaust port 14 after flowing into the cylinder chamber from the intake prot 13, and the air flows through said port 14 as shown by an arrow A.
