Abstract: ELECTRONIC SPARK TIMING ADVANCE CONTROLLER            Abstract of Disclosure An electronic spark timing advance controller for variably controlling the degree of advance or retardation of the firing event of an internal combustion engine integrates an engine speed signal to produce a signal, which is proportional to engine angular position and is reset at a predetermined reference point or angular position of the engine prior to the firing of each cylinder of the engine.  A signal, which is proportional to a predetermined firing angle of the engine, is compared with the engine angular position signal to produce an output signal, which is supplied to spark generating means to produce a spark when the compared signals have a predetermined relation to each other. Additional signals, which vary in accordance with a predetermined engine speed advance characteristic and a predetermined engine vacuum advance character-istic, affect the comparison to vary the firing angle of the engine in accordance with the corresponding engine operating parameters.          Additional control over the engine timing is provided in the subject timing controller in which the spark timing is re-tarded at temperatures below the operating temperature of the catalytic reactor installed on an emission controlled engine.  The operation of the engine at a retarded spark condition increases the temperature of the exhaust gases supplied to the reactor to provide rapid or accelerated warm-up of the reactor to its effective operating temperature.

Abstract: Abstract of the Disclosure An automatic impedance matching network for a transmission line includes an impedance monitor which provides a control signal for two variable compensators. One compensator corrects an impedance mismatch at low frequencies while the second compensates within a higher frequency range.  A directional sensor completes a conductive path for the control signal to the variable compensators only for the direction of signal propagation indicative of the impedance of the transmission line being compensated.  The disclosed arrangement operates auto-matically from the intelligence signals transmitted over the line to provide impedance compensation for a variety of cable sizes of different lengths.                              - i -

Abstract: ABSTRACT OF THE DISCLOSURE            A screw fastening device is described for use on an electrical box or other structure to which a com-ponent is to be fastened by at least one screw.  The device includes a support adapted to be mounted on a flat surface portion of the device.  The support in-cludes a base having a flat inner surface and two spaced side walls which extend outwardly from the base and support the base with its flat inner surface parallel to the flat surface portion of the box when the device is fastened to the box.  The side walls have convergent inner surfaces.  The device also includes a pair of wedge-shaped screw-engaging members which can slide on the flat inner surface of the base and on the flat sur-face portion of the box.  The members have grooved re-cesses which together define a thread complimentary to that of a screw to be received in the device.  Spring means bias the screw-engaging members in the direction of convergence of the side wall surfaces so that, when a screw is inserted between the members, they will slide back and forth along said convergent surfaces as the threads on the screw ride over the corresponding thread defined by the recesses.  The screw will then be held in its inserted position by the screw-engaging members but at the same time can be axially displaced by turning.

The casing consists of two identical halves, each half having walls defining a central, generally semi-annular space for differential pinions and gears, the walls being generated around the center line of the vehicle half-axles. Each half-casing also includes oppositely extending, tubular trunnion halves that also are semi-annular in shape and lie circumjacent the inner ends of the vehicle half-axles when the unit is assembled. There is a radial aperture at the pole of each half-casing in the central portion thereof for the receptionof an end of a radially extending journal pin for the differential pinions. Each half-casing has a semi-circular flange of diameter larger than the central portion of the casing half. When the two half-casings are assembled, a ring gearor crown wheel fits circumjacently to the central portions of the half-casings against and is secured to the flanges. Trunnion bearings fit over the trunnion halves. A "C" shaped ring snaps over the central casing portions and engages the ends of the journal pin which protrude through the polar apertures. The ringgear and trunnion bearings hold the half-casings together as a closed unit and the snap ring holds the journal pin in the casing.

Abstract: APPARATUS FOR VARIABLY SELECTING THE CAPACITY OF A RECORDING MEDIUM IN A RECORDING SYSTEM                   ABSTRACT OF THE DISCLOSURE Apparatus is provided for use in a recording system wherein messages are recorded on a recording medium of fixed length, to variably select the recording capacity of the medium.  An operator-controlled selector permits an operator to establish a preselected capacity which is equal to or less than the total capacity of the medium.  Signals are produced when messages are recorded, and a counter counts these signals, thereby accumulating an indication of the amount of recording medium that has messages recorded thereon.  In one embodiment, the signals that are counted are representative of incremental, lengths of the recording medium so that the accumulated indication in the counter represents the total length of recorded messages.  A comparator compares the accumulated indication in the counter to the preselected capacity and, when the preselected capacity has been attained, a correspond-ing output signal is generated.  This output signal is used to provide a perceptible indication that the preselected capacity of the recording medium has been attained and, in a preferred embodi-ment, also is used to replace the recording medium with a fresh recording medium.         As one type of recording system wherein this apparatus finds ready application, a central dictation system has a central record/playback unit adapted to communicate individually with any one of plural remote dictate stations.  The preselected capacity of the recording medium may be represented as a length of medium, such as a percentage of the maximum length or capacity thereof, or as a selected number of individually established communications, or seizures, between the central unit and the remote stations.     -i-
