Abstract: A mobile communications system comprising a plurality of mobile stations, a plurality of base stations each having in operation a radio communications link with mobile stations in a designated service area served by the base station, and a communications controller for controlling the routing of communications between mobile stations via one or more base stations in the system, the system including selection means for selecting in a group call from a first one of the mobile stations to a plurality of selected others of the mobile stations which of the service areas of the system the call will be sent to, wherein the selection means comprises a database of locations of mobile stations in the system and a processor which is operable to access the database and using information from the database relating to the location of mobile stations which are proposed to participate in the group call to select the service areas or areas of the system to which the call from the first mobile station will be routed or will be

Abstract: A coating for sealing carbon--carbon composites against hydrogen. The coating comprises a first layer of silicon carbide and a second layer of a glass, glass-ceramic or a low-melting-point metal such as tin or an alloy thereof. Particularly when such second layer is a glass, e.g. an SiO.sub.2 -containing glass, or a glass-ceramic, preferably the silicon carbide coating is pretreated, e.g. by oxidation thereof to form a thin layer of SiO.sub.2 prior to application of the glass layer. The glass layer can be an SiO.sub.2 glass formed by sputtering or by decomposition of tetraethylorthosilicate (TEOS) applied to the oxidized silicon carbide coating. An alkali metal oxide, e.g. Na.sub.2 O, or an alkaline earth metal oxide, e.g. BaO, can be added to the SiO.sub.2 glass.

Abstract: An oxidation protection coating for metal substrate surfaces. The coating, according to a preferred embodiment, comprises an initial or first layer of a glass-ceramic, such as a barium aluminosilicate composed chiefly of baria, silica and alumina; or mullite, composed of silica-alumina or, alternatively, baria-silica. Titanium dioxide, nickel oxide or SnO.sub.2 can be added. The next layer of the coating is comprised of alumina or silicon carbide. The third or final layer is comprised of a thin layer of silica or a high-silica material, e.g., a silica containing 4% B.sub.2 O.sub.3. For a thicker third layer, particles of a dark solid, such as boron silicide, ferrous oxide, ferric oxide, nickel oxide, manganese dioxide, carbon or silicon carbide, can be incorporated. The three-layer coating provides high emittance and low catalytic activity for the recombination of oxygen and nitrogen, as well as being a hydrogen diffusion barrier.

Abstract: The present invention is an apparatus for controlling a water delivery system utilizing an instant flow tankless water heater. It includes a programmable microprocessor with support circuitry to achieve control of the outlet temperature of a varying flow rate and varying inlet temperature stream. The system senses a water outlet temperature and controls AC power through an on/off mechanism to regulate power to heating elements embedded in the water stream. The capabilities of the heating elements are improved through the application of using a microprocessor to perform a proportional (P), integrating (I) and derivative (D) calculation. The calculations are used to determine the operating characteristics of the heating system and to control the heating system.

Abstract: A steering system for use in a towing vehicle-steering trailer assembly, wherein all trailer axles are load-bearing and fixed. The steerable trailer includes a sectored radian steering mechanism which comprises a sectored rack-and-pinion mechanism keyed to the towing vehicle fifth wheel plate. The sectored rack-and-pinion mechanism provides a steering output signal proportional to the relative angle between the towing vehicle and the steerable trailer which approaches an asymptote and thus allows the towing vehicle to turn in relation to the steered trailer without generating the steering mechanism output signal.

Abstract: A removable gooseneck for detachably connecting a tractor and trailer utilizes an elongate beam member attached to the hitch of the tractor and having an upstanding frame member depending from a rear end of the beam member. A foot is pivotally mounted at a lower end of the upstanding frame member for engagement with a front end portion of the trailer. A guide pin and link arrangement detachably connects the foot at a front end to the trailer and a locking pin and bushing arrangement detachably connects the rear end of the foot to the trailer at a location spaced from the guide pin and link arrangement. A power fluid ram extends between an upper portion of the upstanding frame member and the foot to selectively cause the foot member to swing upwardly and tilt the trailer downwardly for detachment of the gooseneck from the trailer and swing the foot downwardly to tilt the trailer upwardly for drafting.

Abstract: Initial cell voltages are reduced by decreasing the resistance of the diaphragm through a degassing procedure prior to or at installation thereof. This degassing procedure involves subjecting the diaphragm to subatmospheric pressure while contacting the diaphragm with electrolyte, said electrolyte being an aqueous saline solution having a surface active agent therein in an amount sufficient to reduce the surface tension below the critical surface tension for wetting the fibers, and increasing the pressure to atmospheric or cell working pressure to force electrolyte solution into the interstices of the diaphragm.
