Abstract: INVENTOR:   BARRY L. MACKY TITLE:      REVERSIBLE HAMMER DRILL            ABSTRACT OF THE DISCLOSURE    When the hammer drill spindle and chuck are driven forward with the mode selection collar positioned to allow axial movement of the chuck and spindle, the annular ratchet is driven by the spindle through a one way roller clutch so it rides up the sloping surfaces of the fixed annular ratchet and then drops off the tooth corners to deliver a hammer blow of a magnitude determined by the operator pushing on the tool.  If the rotation is reversed the clutch prevents rotation of the clutch input and prevents injury to the operator.          If the selection collar is moved to lock the lugs in the detent notch of the cam surface the drill can be rotated either direction with the hammer action always locked out.

Abstract: ABSTRACT OF THE DISCLOSURE           A video signal processing circuit eliminates an inter-fering signal that is included in a video signal, and is especial-ly effective for eliminating an interfering signal that results from reproducing a video signal that is recorded in successive slant tracks on a recording medium, such as magnetic tape.  In the video signal processing circuit, a delay line delays at least the luminance component of the video signal by a predetermined number of horizontal line intervals, a first subtracting circuit combines the delayed luminance component with the undelayed lumin-ance component to produce a first difference signal, a limiter limits the first difference signal and presents the limited first difference signal to a second subtracting circuit, where the lat-ter signal is subtractively combined with the delayed luminance signal to produce an output signal free of interfering signals. In order to improve the performance of the processing circuit, a high pass filter and an adder circuit can be included to pass the high frequency portion of the first difference signal around the limiter.  Alternatively, a deemphasizing circuit and a preemphaz-ing circuit can be respectively included in advance of, and following, the limiter.

Abstract: ABSTRACT:          "Receiver for digital-signals in line code".     Receiver for a digital line code signal. This receiver comprises a line code decoder and a digital-to-analog converter. To reduce the audibility of bursts this receiver also comprises a line-code violation detector detecting whether the received signal deviates from the line code; as well as a pulse generator. Each time the line-code violation detector detects that the received signal deviates from the line code,the output signal of the pulse generator is applied to the digital-to-analog converter instead of the output signal of the line code decoder.           Such a receiver can be used in a digital tele-communication system, but is also suitable for reproducing recorded signals, for example magnetically recorded signals.

Abstract: MULTIPLE-BEAM OPTICAL SENSING SYSTEM FOR AN              ARTICLE VENDOR            Abstract of the Disclosure A multiple-beam optical sensing system for an article vendor having a delivery station to which an article to be vended is delivered during the vend which system includes first and second optoelectronic emitters, first and second optoelectronic detectors, a circuit for energizing the emitters, and a logic circuit.  The emitters emit electromagnetic radiation across the delivery station to the detectors, each detector being disposed across the delivery station from its respective emitter.  When no article is pre-sent at the delivery station, the radiation from the emitters is unobstructed in its passage across -the delivery station from the emitters to their respec-tive detectors.  When an article is present, however, the radiation is at least partially obstructed.  The detectors detect the presence of an article at the delivery station by the obstruction of the radiation from their respective emitters.  The energizing circuit enables the emitters alternately so that when one emitter is enabled the other is disabled.  The logic circuit determines that an article is present at the delivery station by examining the detectors in turn, a detector being examined only when its corresponding emitter is enabled.

Abstract: Abstract of the Disclosure A distinction of the method resides in that, at the moment of release of ore the ore flow in the zone of an outlet opening is divided into at least two parts by a vertical plane, and the ore flow is caused to swing transversely with respect to the direction of ore flow by alternately changing the density of ore in the portions of the flow, oversized lumps of ore delivered to a loading drift being transferred along a ramp by-passing haulage vehicles to ventilating and man roads which are arranged at the level of haulage crosscuts and connected thereto at points opposite to loading drifts.  A distinction of an apparatus for carrying out the method resides in that a working surface of a platform consists of three rigidly interconnected portions, the end portions extending in parallel and at different levels, and a central portion is inclined in the direction of ore flow.

Abstract: Method for Making Stable Nitride-Defined Schottky Barrier Diodes Abstract Excessive leakage after initial forward stress, exhibited by subsequently reverse stressed nitride defined, Schottky barrier diodes is solved by the elimination of the "mouse hole" or undercut cavity in the oxide layer beneath the nitride ring defining the Schottky contact to the underlying silicon.  The aforementioned cavity is filled by depositing chemical vapor deposited (CVD) oxide onto the nitride layer, into the nitride ring and the undercut oxide cavity beneath the ring and onto the underlying silicon substrate exposed through the nitride ring.  The CVD oxide is then reactively ion etched to remove it except along the vertical walls of the nitride ring and the oxide cavity.  The Schottky metal is deposited on the silicon substrate exposed by the reactive ion etching step.
