Abstract: Abstract of the Disclosure An electrostatic spray coating gun for applying coating materials which have high to moderately high electrical conductivity is disclosed.  The gun has an improved high voltage electrical system, improved hydraulic seals, and is adaptable to apply porcelain enamel coatings in slurry form. The gun has a flexible and resilient electrode in the form of an elongated coil spring.  This form of electrode substan-tially eliminates the likelihood of scratching or puncturing the skin of an operator or repairman, and allows the electrode to return to its proper orientation after being bumped, while exhibiting proper paint charging characteristics for use in electrostatic spray coating.  The electrode is positioned forward of a flat-fan spray nozzle and is displaced from the axis of the spray by means of an extension assembly which can be angularly displaced about the axis of the spray.  The gun further incorporates improved packingless bellows sealing between an opening into the coating conduit in the barrel of the gun and a control rod for a needle valve in the conduit. Novel static seals allow the use of a bellows in the form of a non-machined extruded fluorinated hydrocarbon commonly known by the trademark Teflon.  The packingless seals, properly designed flow passages, the position of the charging electrode, and wear resistant material at the nozzle tip and needle valve allow the gun to be used not only for the electrostatic spraying of the common electrically conductive coating materials, but also for abrasive coating materials, such as glazes, in slurry form.

Abstract: METHOD OF MAKING FIELD EFFECT TRANSISTOR    Abstract of the Disclosure A fabrication method for providing electrical isolation between transistors such as field effect transistors (FETs) which are fabricated on the same semiconductive substrate is described that uses a single doping step to form both the channel stopper field doping and the FET channel doping.  An example of an n-channel FET embodiment is described wherein an extra p-type doping is provided in the field region which serves to prevent parasitic conductive channels from occurring under the thick field oxide.  Such parasitic channels can undesirably cause electrical shorting between adjacent FETs of an integrated circuit.  Extra p-type doping is also provided in the FET channel region and serves to raise the gate threshold voltage of the enhancement-mode FET to a level suitable for integrated circuit operation.  In the described method a single implatation or diffusion doping step provides both the field and channel doping regions, thereby reducing the number of processing steps.  This single doping step is facilitated by use of a thick field isolation oxide which is chemically vapor deposited at a relatively low processing temperature after per-forming the common doping step.

Abstract: Abstract of the Disclosure A common control circuit is disclosed for controlling bypassing relays to disconnect telephone line auxiliary circuits from their respective lines preparatory to line testing or for other desired purposes.  The control circuit responds to a bypass request signal applied to a line by operating an associated bypassing relay and by activating a timing circuit.  The timing circuit and other circuitry cooperate to hold the bypassing relay operated for a time interval sufficient for fulfilling the purpose of the bypass.  For serving a bypass request received while another request is being served, the appropriate bypassing timing circuit is reactivated to insure a sufficient test time for the subsequent request.  All operated bypassing relays are held operated until the expiration of a time interval during which no new bypass requests are received.  The control circuit includes monitoring circuitry operative to detect selected internal and external failure conditions.

Abstract: COLOR TELEVISION CAMERA     Abstract of the Disclosure The present invention is a color television camera employing a single pick-up tube and producing color component signals utilizing a difference of phase relationships of the modulated color signals, at least one of which changes in successive horizontal scan lines.  In such a color television camera, the amplitude of a modulated component signal is controlled by a color error correction signal which is produced from the unmodulated component signals derived from adjacent horizontal line scans, so that color error components are not carried into the color component signals.

Abstract: MOUNTING ASSEMBLY AND METHOD FOR FOOD WASTE DISPOSER        Abstract of the Disclosure A simplified mounting and sealing assembly for rapidly attaching a food waste disposer to a sink includes a sink flange which is inserted into the drain opening in the sink and has an elongated neck extending below the sink.  An annular pressure plate is received on the flange neck below the sink, and is tem-porarily supported by bosses or protuberances on the flange while also capturing the flange in the sink opening.  An annular groove is formed in the flange neck below the bosses and a snap ring which is held captive in the disposer engages this groove upon lifting the disposer over the neck.  The groove and snap ring hold the disposer on the flange so it is free to be rotated for making electrical and drain connections.  An annular flange seal is received in the disposer and an annular compression plate rests on the upper surface of this seal.  Jack screws extend between this annular compression plate and the pressure plate to lift the annular pressure plate against the bottom of the sink, compress the annular seal and lock the disposer against movement.  The jack screws are threaded into the compression plate and force it down-wardly against the seal to cause the seal to engage both the neck of the flange and the disposer at the same time that the pressure plate is lifted up against the bottom of the sink.  The arrange-ment is such that extending the jack screws to lift the pressure plate and compress the flange seal does not alter location of the disposer with respect to the sink or previously completed plumbing-electrical connections.

Abstract: HOLDER FOR ANNULAR FILTER                        ABSTRACT           Holder for an annular filter includes a support frame or basket with a flared portion at its upper end which cooperates with the inner leg of an inverted U-shaped sealing ring to clamp the upper end of the filter.  The sealing ring has its outer leg seated on a sealing gasket positioned on top of a support plate surrounding an aperture through which the filter is lowered during operation of a particle collection apparatus.  The holder is replaceably sealed in position by screwing a pair of threaded rings together to force the flared portion downwardly.  The diameters of the various parts are larger than the aperture to prevent them from being dropped through the aperture and the overall design is such that the filters can be replaced from the upper clean side of the col-lection apparatus rather than the lower dirty side.

Abstract: IMPROVED FIBER FORMING BUSHING CONSTRUCTION                   Abstract of the Disclosure In apparatus for heat-softening and attenuating glass material into fibers, an improved low temperature electrical resistance bushing having extremely thin side walls and other electricity conducting components running from end to end in the bushing, relative to the base plate for both direct and marble-melt bushings.  The thin side walls enable a low temperature bushing to operate with temperatures less than 2250° F., because the thin side walls draw proportionately less current than the base plate.  Additional improvements for providing a low tem-perature bushing include, for a marble-melt bushing, a funnel which is mounted on the top wall and a cooling tube mounted adjacent a bottom portion of the funnel.  Another improvement includes the use of auxiliary end plates mounted adjacent the end walls of the bushing for channeling electrical current to the base plate.  A further improvement in a marble-melt bushing includes the provision of opposed side walls which are inclined outwardly as well as extend upwardly from the base plate.  Upper side wall sections are inclined inwardly from an associated side wall.  The result is a construction in which a bridge of glass material may be supported somewhat by the side walls.
