Abstract: SNAP-IN SEALING AND INSULATING MEMBER FOR GALVANIC   CELLS            ABSTRACT OF THE DISCLOSURE            In a sealed galvanic  seal having an anode,  a  cathode, and  a  cylindrical  can   into  which   the   principal components  of  the cell  are assembled, a  sealing  and insulating member  is provided  at  the  top  end of the cathode can, and is  held in sealing relationship to the can by  a crimp formed  over the top  edge thereof.  The sealing  and insulating member is formed  with an  upper portion having  a diameter which  is  substantially  the same as the  inside  diameter of the  can  in the region above the bead,  and has an inwardly  directed  shoulder in  the periphery of the member to a diameter  which  is substantially  the  same   or  slightly  less  than  the diameter  of the  can at the bead.  Below the  shoulder, there  is  a  downwardly and outwardly  extending  skirt formed  in  the  lower   portion  of  the   sealing  and insulating member,  the maximum  diameter  of  which  is located  substantially at the lowest  extremity thereof, and  which  is greater than the diameter of  the can at the bead.   The  sealing  and  insulating member may  be snap-fitted into the can prior to  crimping, and held in place without the necessity to  pre-crimp.  Moreover, by such an assembly,  there  is  a greater internal  volume provided in the cathode can.     File No. PAT2018

Abstract: Abstract of the Invention Lightweight aircraft transparencies are shaped to a desired con-figuration by laying up a plurality of flat oversized plastic sheets in a desired sequence to form a flat assembly. Portions of the marginal edges of the flat assembly are supported on a female support ring having a non-planar supporting surface.  The assembly is first shaped at a temperature below its deformation temperature to a preliminary shape where its marginal edge portions  conform to the non-planar supporting surface of the female support ring.  While the marginal edges of the preliminarily shaped assem-bly are maintained in conformity with the female support ring, the assembly is uniformly exposed in an enclosed autoclave to elevated pressures to minimize outgassing and to elevated temperatures above its deformation temperature.  A male form having an outline smaller than the female support ring engages the central portion of the preliminarily shaped assembly to impress the desired final shape thereto, e.g., a compound configuration. Thereafter, the marginal edge portions of the finally shaped and laminated assembly are trimmed away to leave the central portion of the assembly with a desired shape.

Abstract: ABSTRACT:       Contemporary communication networks, telephone exchanges in particular, are usually equipped with a com-prehensive central control. A result thereof is that they are very complex.  The invention provides a communication network having a high degree of distributed control and processing by providing a binary switching element from which selector stages, selectors and selector systems are assembled, which are employed in the whole network.  The binary switching element (1) comprises a device (15) which connects an input (11) to both a zero-output (12) ]       and a not-output (14) and a device (15') connecting the input (11) to both a one-output (13) and the not-output (14).  One of the outputs (12, 13, 14) is activated depending on the logic value of the binary input signal and the presetting of the devices (15, 15').  An arbitrary large, flexible, simple and reliable communication network can be assembled by arranging these binary switching ele-ments in series and/or in parallel.

Abstract: INTEGRATED ALTERNATOR BRIDGE HEAT SINK   ABSTRACT      An apparatus is provided for sinking heat from the diodes of an alternator bridge whereby the heat is transferred directly to the alternator casting.  A mounting base is mounted on the alternator case in a manner to provide both thermal and electrical conductivity.  A thin layer of thermally conductive, but electrically isolating, epoxy is sandwiched between a plate and a portion of the mounting base.  "Negative" diodes are placed on the mounting base and "positive" diodes are placed on the plate so that electrical contact is made.  Heat from the "negative" diodes is transferred through the mounting base and from the "positive" diodes through the plate and mounting base to the alternator casting, thereby reducing the thermal resistance and eliminating a need for large, "finned" heatsinks.  The "negative" diodes or "positive" diodes may comprise a low voltage avalanche die, thereby providing for high energy transient suppression in the alternator.  Trio diodes and a radio suppression capacitor may be mounted directly on the mounting base or plate.

Abstract: ABSTRACT     A process for drying and deoxygenating coal-oil slurry prior to liquefaction of the coal.  In the process, the coal having particle size of 30-375 mesh (U. S. Sieve Series) is mixed with a slurrying oil derived from a coal liquefaction process  at  250-650°F  mixing  temperature  and  0-150  psig pressure.   During the mixing step, moisture in the coal is evolved to less than about 3.0 W % moisture remaining, along with  substantial  removal  of the oxygen contained in the coal.  The process produces a dried more reactive coal slurry for feed to a coal liquefaction process for achieving increased  conversion  of  the  coal  and  producing  more desirable low boiling hydrocarbon liquid products.

Abstract: ABSTRACT In a battery operated, remote transmitter for a consumer instrument, a microprocessor controls operation of the transmitter.  The collector current path of an on-off transistor is coupled between the battery and a voltage supply terminal of the microprocessor.  To power up the microprocessor,a keyboard switch in the transmitter is depressed to activate a separate latch that is coupled to the base of the on-off transistor.  Base current flows to the latch to turn on the transistor and apply the battery voltage to the voltage supply terminal of the microprocessor.  After completion of the transmitter signaling, the microprocessor switches an output port to the ground state.  The output port is coupled to a control terminal of the latch and bypasses holding current from a portion of the latch to initiate the regenerative deactivation of the latch.  With the latch deactivated, conduction of the on-off transistor is cut off.  The voltage supply terminal of the microprocessor is disconnected from the battery to power down the remote transmitter.
