Abstract: When computing a least weight path from an origin node to a destination node in a data communication network, a route-computing network node uses information provided by the origin and destination nodes to compute least weight routes from those nodes to adjacent network nodes. The route-computing network node uses information in the topology database to compute least weight routes from network nodes adjacent the origin node to network nodes adjacent the destination node. The results of the compu­tations are combinated to determine an optimum route from the origin node to the destination node. The topology database need not include information about the transmis­sion groups connecting the origin/destination nodes to network nodes.

Abstract: A hydraulic control system for, e.g., electrically driven vehicles, comprising a hydraulic, double-acting steering piston-cylinder device which co-acts with a control unit which is actuable by means of a steering member, and which is connected to a hydraulic pump, driven by an electric motor, and to a tank, and which includes a control signal outlet through which a control signal is delivered for maintaining and interrupting the supply of steering hydraulic fluid to the steering-­piston cylinder device. In order to enable the vehicle to be steered directly, even when the pump is not acti­vated, an accumulator (20) is provided in the hydraulic connection (12) between the pump (11) and the control unit (8), at a location between two counter-directional check valves (17, 19) which prevent the flow of hydrau­lic fluid from the accumulator (20) and of which valves the valve located upstream of the accumulator (20) is intended to open in response to the control signal delivered by the control unit (8), this control signal constituting a pressure increase, so as to permit hy­draulic fluid to flow from the accumulator (20) to the steering piston-cylinder device (1). The system also includes means (39, 40) operative to start the pump motor (13) upon the occurrence of a pressure decrease in the hydraulic connection (12) between the two check valves (17, 19), therewith to provide the requisite flow of hydraulic steering fluid through the action of the pump (11).

Abstract: A transport refrigeration system (10) which includes a compressor (14), a condenser (24), a receiver (26), an evaporator (42), an accumulator (44), and a control valve (18) which selectively initiates heating and cooling cycles. The heating capacity of a heating cycle is enhanced by connecting an outlet (28) of the receiver to an inlet (77) of the accumulator just prior to each heating cycle, while maintaining the control valve in a cooling position for a predetermined time delay (82). This forces any liquid refrigerant trapped in the condenser to flow into the receiver, while lower pressure in the accumulator causes liquid refrigerant in the receiver to flow into the accumulator, to provide additional liquid refrigerant in the accumulator at the start of the heating cycle, which is initiated at the end of the predetermined time delay.

Abstract: Methods of coating stereolithographic parts and smoothing over characteristic surface discontinuities having alternating recesses and peaks. A stereolithographic part is first substantially covered with a substance capable of becoming less viscous when heated at a temperature which does not substantially thermally degrade the part, wherein the heated substance has an appropriate surface tension. Then, the substance is heated to that temperature until the substance flows preferentially into the recesses of the surface discontinuities and away from the peaked surface discontinuities. The substance will thereafter form a short surface connection over the recesses of the discontinuities through the surface tension of the heated substance. The substance is then polymerized or hardened either by cooling, thermally setting or by UV curing.

Such self-generated vacuum infil­tration occurs without the application of any external pressure or vacuum. The molten matrix metal (13) infiltrates the filler material (11) up to at least a portion of a provided barrier means.

Abstract: A method and system for accurately inspecting an electroconductive film using an eddy current and a process and apparatus for production of an optical fiber which measures on-line the electrical resistance, which shows the state of formation of the electroconductive hermetic coating of the optical fiber by the electroconductive film inspection method and reflects back the measurement results to the hermetic coating forming conditions are disclosed. Optical fiber is made up of a core, cladding, amorphous carbon film or other electroconductive hermetic coating formed on the outer surface of the cladding, and a protective coating. The electrical resistance of the hermetic coating generates an eddy current at the coating, the eddy current generated is detected, and the phase angle of the complex impedance is detected to enable calculation. In particular, to accurately detect the phase angle, the high frequency current for generating the eddy current is changes by a low frequency of about 1/100th of the high frequency to change the average intensity and obtain at least two points of measurement defining the above phase angle. The electrical resistance of the hermetic coating is calculated from this phase angle. The electrical resistance shows the state of formation of the hermetic coating. The measurement value of the electrical resistance of the hermetic coating is used for setting the hermetic coating production conditions. The electroconductive film inspection method of the present invention may also be used for quality control etc. of thin films.
