Abstract: RCA 72,056 GATED AUTOMATIC BEAM CURRENT LIMITER IN A VIDEO SIGNAL PROCESSING SYSTEM              Abstract Of The Disclosure In a video signal processing system including a clamp for clamping the video signal to a reference level during periodic image blanking intervals of the video signal, and a kinescope for reproducing an image in response to the clamped video signal, apparatus for automatically limiting excessive beam currents drawn by the kinescope.  A derived control signal representative of the magnitude of excessive beam currents is applied to the video signal processing path prior to the clamp.  The control signal is inhibited during the blanking intervals, and serves to offset the D.C. level of the video signal in the black direction during image trace intervals to reduce the current conduction of the kinescope.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved battery charger of the type having a housing with a source of electrical energy therein suitable for recharging units capable of being electrically recharged.  The housing includes a plurality of cavities each arranged to accommodate a unit to be recharged, and each cavity has electrical contacts which are positioned to contact the terminals of the unit inserted into each cavity for delivering electrical energy to that unit.  The improvement comprises a switch in each cavity which is activatable by insertion of the unit therein, the switch being separate from and free from direct contact with the electrical contacts, but electrically connected to the energy source which, in turn, energizes the electrical contacts for recharging the unit upon activation of the switch.      A battery pack unit capable of being recharged including a housing with a first pair of electrically conductive metallic strips on the outside of a side portion thereof, and a second pair of metallic strips on the outside of a top portion of the housing.  A plurality of batteries is in the housing, the batteries being electrically connected to each other and to both pairs of the metallic strips.  One of the strips in each pair is negative terminal and the other strip in each pair is a positive terminal for the pack unit.

Abstract: SERVO CONTROL APPARATUS                ABSTRACT OF THE DISCLOSURE           Servo control apparatus for controlling the speed and phase of a driven member.  Reference signals, having a frequency determinative of the speed at which the member is driven, are compared to actual speed-representing signals in a servo loop, whereby the member is driven at the speed determined by the reference signals.  An actual position-representing signal, representing the position, or phase, of the driven member, is derived.  A window pulse generator generates window pulses corresponding to desired positions of the driven member.  The occurrence of these position-representing signals within the duration of the window pulses is detected. A frequency modulat-ing circuit modulates the frequency of the reference signals if the position-representing signals occur outside the window pulses, so as to adjust the speed and position, or phase, of the driven member until this member is driven such than its actual positions correspond to the desired positions. In accordance with a further aspect of this invention, the phase of the reference signals is adjusted such that the position-representing signals occur at a predetermined location within each window pulse.  The driven member can be a rotary transducer or a movable record medium in, for example, a video signal recording/reproducing system.

Abstract: CONSTANT VOLUME, CONTINUOUS EXTERNAL COMBUSTION ROTARY ENGINE WITH PISTON        COMPRESSOR AND EXPANDER     Abstract of Disclosure Constant volume, continuous external combustion rotary engine which incorporates at least one radial piston compressor, at least one continuous-combustion chamber, at least one radial piston expander together with a means to supply fuel to the combustion chamber.          A novel arrangement of compressor and expander mani-folding controls admission and discharge to and from the compressor and expander sections.  Power output is realized when opposed expander pistons equipped with roller bearings react directly on the internal cam lobe surfaces of a stationary housing causing the cylinder block to rotate and drive the compressor piston inwardly or outwardly as their roller followers engage their cam tracks. As a fresh charge of compressed air is delivered to the hydrocarbon fueled combustion chamber, an equal amount of combustion product under almost equal pressure is withdrawn by the expander.          When combustion charging is completed, both compressor and expander are momentarily disconnected from the com-bustion chamber.  The isolated combustion process continues, at constant volume, causing a pressure rise until the expander admission valves open again.  Mechanical work is produced as the expander pistons are moved outwardly, initially under the almost constant pressure of the combustion chamber and then at a decreasing pressure as the expander pistons continue to expand the combustion product after the expander admission valves have closed.  An exhaust discharge stroke commences as the expander piston after completing the expansion stroke, returns inwardly to the inner dead center position.  Simultaneously a new charge of ambient air is induced by the compressor as the compressor piston moves outwardly to the outer dead center position, and the cycle repeats as the fresh charge is compressed for discharge to the combustor.

Abstract: ABSTRACT OF THE DISCLOSURE    A hydraulic engine for transforming the energy of a flowing current of water into a pressure head of water.        The engine is mounted on a platform supported by floats and fitted with a series of paddles linked by drive chains which pass about a pair of drive wheels such that flow of water over the platform causes the paddles to move in the direction of flow to rotate the drive wheels with the paddles and chain being elevated above the water level for return travel.  A drive wheel is joined by a shaft to a cam wheel against which an end of a piston shaft is engaged so that rotation of the cam wheel causes re-ciprocal travel of the piston shaft with the piston en-closed in a cylinder that pumps water up through a ver-tical pipe to create a pressure head of water for driving a generator engine.  The cam wheel is shaped so that the reciprocal travel of the piston may be varied depending upon the radial position of the piston shaft.  A tele-scopic hydraulic unit supports the cylinder on the plat-form so that radial position of the piston shaft may be varied to suit the condition of water flow.
