Abstract: SPARK  PLUG TERMINAL          Abstract of the Disclosure:         A two-piece socket terminal is crimped to the end of an ignition wire and detachably connected to a spark plug stud terminal.  The terminal comprises an attachment member of crimpable semi-hard steel having a corrugated channel at one end and a tee shaped support at an opposite end, and a socket member of spring tempered steel having a split sleeve at one end and a longitudinal tongue at an opposite end.  The attachment and socket members are secured to each other by clamping arms of the tee-shaped support bent over the longi-tudinal tongue.  The tongue has circumferential tabs behind the clamping arms providing a mechanical interlock in the pull-off direction while the foremost internal rib of the corrugated channel provides a stop in the push-on direction.          The terminal provides a direct electrical connection between the ignition wire conductor core and the socket piece which is enhanced by forward projecting tabs of the corrugated channel.  In-line and angled embodiments are disclosed.

Abstract: FLUID PRESSURE GENERATOR                       AND VALVE MEMBER THEREFOR                       ABSTRACT OF THE DISCLOSURE        A fluid pressure generator, such as a master cylinder, includes a housing with a bore for movably supporting a pair of pistons,  The pair of pistons cooperate with the housing and with each other to substantially define a pair of pressure chambers which are communicated with respec-tive brake assemblies.  A first piston of the pair of pistons is mov-able within the housing to pressurize a primary pressure chamber and the second piston of the pair of pistons is movable in response to pressurized fluid within the primary pressure chamber so as to pres-surize a secondary pressure chamber.  The second piston carries a valve assembly and includes a passage to provide fluid communication between the secondary pressure chamber and its respective brake assembly.  The valve assembly is movable in response to the pressure of fluid within the secondary pressure chamber and a shuttle member is movable in response to a pressure variation between the primary pressure chamber and the secondary pressure chamber to move the valve assembly to a position opening the passage.  The valve assembly is disposed within the second piston and is defined by a sleeve and a pilot member.  The sleeve slidably receives the shuttle member within a bore on the sleeve and the pilot member is connected to the shuttle member.

Abstract: Abstract of the Disclosure A system and method of securing the end shields of a dynamoelectric machine (e.g., a fractional horsepower electric motor) to its stator assembly with the rotor assembly of the motor held centered within the bore of the stator assembly and journalled in the motor's end shields.  The system involves the use of threaded fasteners (preferably self-tapping screws or the like) which are inserted through enlarged holes provided in the end shield into mating holes provided in the end face of the core of the stator assembly.  With the rotor accurately centered in the stator bore, the fasteners are tightened thereby to firmly and securely draw the end shield into firm gripping engagement with the end face of the stator core while the desired uniform air gap between the rotor and the bore of the stator assembly is maintained.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved plating technique which is especially adapted for galvanizing one side of a strip of steel has been developed.  According to the technique, an anode assembly is positioned in relatively closely spaced relation-ship with the workpiece.  The assembly and workpiece are configured to establish a fluid flow path for plating fluid. The plating fluid is supplied in a quantity sufficient to maintain at least a portion of the flow path across the workpiece substantially filled at all times with flowing solution so that plating is accomplished across the entire width of the workpiece.  A major advantage of the invention is that the fluid flows over only selected portions, such as one side of the workpiece.  Another major advantage is that because there is a relatively high rate of flow, good ion replenishment rates are provided permitting the use of non-consumable anodes to provide the advantages in plating that are characteristic of nonconsumable anodes but overcoming the deficiencies of nonconsumables that have in the past limited their use and have resulted in waste, inefficiencies and high capital investment.

Abstract: RCA 73,977 Abstract of the Disclosure A signal separation network is provided which accomplishes the functions of a sound take-off network and intercarrier sound trap in a single network.  A common detector produces detected composite video and inter carrier sound signals.  Circuitry is provided for processing the composite video signal, and a separate circuit is provided for processing sound information.  The signal separation network has an input responsive to the detected composite video and intercarrier sound signals, a first output terminal coupled to the input of the video processing circuitry, and a second output terminal coupled to the input of the sound processing circuitry.  The network is characterized by a transfer function which exhibits a dominant zero approximately at the intercarrier sound frequency at the first output terminal, which provides trapping of the intercarrier sound signal in the path to the video processing circuitry.  The network is also characterized  by a transfer function at the second output terminal which exhibits a dominant pole substantially at the intercarrier sound frequency and a zero at a lower frequency so as to peak the response at the second terminal around the intercarrier sound frequency.  The intercarrier sound signal is therefore prefiltered by the bandpass characteristic at this second terminal and is then applied to the sound processing circuitry.  The network may be arranged in either a series tuned or a bridged-T configur-ation, and may also be arranged so as to exhibit a zero in the transfer function at the second output terminal which provides attenuation of mid-band video signals in the sound channel.

A nozzle or mouthpiece is located at the forward end of the body shell.   The body shell is open at the rear end.   A sleeve is fitted on the outside of the rear end portion of the body shell and is rotatable and axially movable with respect to it.   The sleeve has a rear wall which closes the open rear end of the chamber.   A capsule retaining means extends through the rear wall of the sleeve into the chamber.   The capsule retaining means has an external entry opening for a capsule at the rear of the sleeve.   An abutment is fixed inside the chamber in such a position with respect to the retaining means that a capsule retained in the retaining means and projecting from it into the chamber will engage the abutment when the sleeve is rotated with respect to the body shell.   This separates the projecting portion of the capsule from the remainder of the capsule.   A grid or guard prevents the separated portion of the capsule from passing through the nozzle or mouthpiece.   An air inlet opening extends through the rear wall of the sleeve into the chamber.
