Abstract: RCA 74,957 Abstract of the Disclosure An I.F. amplifier system is provided in which gain control is accomplished by varying the A.C. impedances of variable impedance devices, which devices are coupled as load and emitter degeneration impedances for amplifying transistors.  Variable D.C. gain control currents are applied to the variable impedance devices to vary their impedance.  When coupled as collector loads, gain control is achieved by varying the load lines of the amplifiers. When coupled as emitter impedances, gain control is achieved through variable emitter degeneration.  These two techniques of gain control are employed in respective different amplifying stages, which reduces the maximum amount of gain control current required at any particular point in the gain control process, thereby reducing the power consumption of the system.

Abstract: LINEAR MAGNETIC BEARING                        Abstract A linear magnetic bearing includes a stator member stationary relative to x, y and z axes and having a longitudinal axis on the z axis as well as a member longitudinally translatable relative to said axes.  The translatable member      is controlled to have a longitudin-al axis coincident with the z axis.  Permanent magnet means on one of the members positions the translatable member      in a plane defined by the x-y axes relative to the stationary member.       The position of the translatable member      is sensed by sensors          relative to the stationary member      in the plane defined by the x-y axes. Electro-magnet means         on one member          responds to the sensor             to center the longitudinal axis of the translatable member      on the z axis.  First low reluctance magnetic flux paths for the permanent magnet means             exist through both of the members and a radial air gap             between the members. Second low reluctance magnetic flux paths exist for the electro-magnet means through both of the members and a radial air gap            so no net force is applied to the translatable member in the direction of the z axis by either the permanent magnet means or the electro-magnet means. The first and second low reluctance flux paths are arranged so that both the electro-magnets and permanent magnets share: a common air gap but the electro-magnet fluxes do not pass through the high reluctance permanent magnets. One of the members includes two fixedly spaced elements along the z axis.  Each fixedly spaced element has four radial pole faces for the permanent magnet flux pathe.  At least two of the radial pole faces of each element provide x and/or y position control via the electro-magnet flux interaction with the permanent magnet flux in the common air gaps.

Abstract: Abstract of the Disclosure The invention relates to a low current, low voltage generator for use in an underwater lighting system.  The generator is driven by a commercially available source of power, for example, house current.  The generator consists of an AC motor having an output shaft and a magnet mounted on the shaft for rotation therewith.  A coil arrangement is disposed in a plane parallel with but spaced from the plane of the magnet.  The magnet is cylindrical in shape and includes a slot in the front face thereof which faces the coil arrangement.  Thus, when the magnet is rotated, it produces an EMF in the coil arrangement to provide a low current, low voltage AC output at the output of the coil arrangement, which can be rectified to provide a DC output if required.

Abstract: RCA 75,602 Abstract of the Disclosure Apparatus is disclosed in a video signal processing system for automatically monitoring and controlling the blanking (black) current level of an image reproducing kinescope.  A kinescope cathode output signal proportional to the level of cathode black level current conduction is induced during periodic monitoring intervals during which image signals are absent.  The cathode signal is induced in response to a grid drive pulse applied during the monitoring intervals.  The induced cathode signal is processed by a digital signal processing network to produce incremental bias control voltage steps for modifying the cathode bias, if necessary, in a direction to produce a desired cathode black current level.  In addition, there is disclosed a special form of grid drive pulse which serves to prevent system "hunting" in the vicinity of the correct cathode bias.

Abstract: CENTRIFUGAL ACTUATOR FOR                 A.C. INDUCTION MOTOR                      Abstract A centrifugal actuator for activating a sta-tionary switch in a single phase induction motor which has a hub with a central opening inside a central body portion for assembly and securement on the shaft of a motor for rotation thereby.  The hub has a flat outer member for contacting the switch to actuate starting windings of the motor when the motor is in a rest con-dition and is removed from the switch under centrifugal action by weights located inside the actuator to cut out the starting windings when the motor is in a run con-dition.  The central body portion of the hub which extends toward the motor over the motor shaft and receives a base of magnetic material which has side members also of magnetic material connected thereto which with the base provides an envelope enclosing the weights and other internal parts of the actuator located inside the centrifugal actuator.  This prevents the flow of magnetic flux from the windings of the motor to the enclosed parts of the actuator.  The weights are secured to hinges in turn secured to the side members and the weights pivot free of the base when the actuator is moving from a rest to a run position around knife edges or abutments pro-vided on the body of the hub.  Objectionable rattling during coastdown is prevented by preloaded tabs formed integrally with the base which are lodged in preloaded recesses in the body of the hub and the preload of the tabs must be overcome before the hub will rattle on the motor shaft.  The preloading of the tabs and recesses is provided by springs which extend diametrically across both sides of the actuator.

Abstract: ABSTRACT          A horizontal continuous casting apparatus is described.  The apparatus has a take off device supported upon a frame, drive rolls, counter pressure rolls and clamping devices for urging the pressure rolls against the drive rolls.  The drive rolls, pressure rolls, drive shafts and clamping devices are held in a mounting adapted to be rotated, in relation to the frame, about the longitudinal axis of the casting and locked in position.  This makes it possible to take off a casting, for example one having a square or rec-tangular cross-section, in a position in which a diagonal of the said cross-section runs vertically, whereas for the take off of cross-sectionally circular castings, the shaft of the drive roll can be set in a horizontal position. This makes it possible to arrange the take off of the casting in such a manner that the incompletely solidified casting exhibits optimal rigidity.

Abstract: DUAL WAVELENGTH OPTICAL SYSTEM          Abstract of the Disclosure In dual wavelength equipment such as a combined read/write unit for an optical disc system, read light of wavelength .lambda.1 is directed through an isolator and a combiner, is reflected from a target back through the combiner and, at the isolator is directed out of the incident beam path to photodetectors.  Write light of wavelength.lambda.2 is directed from a position off the read beam path to the combiner where it is re-directed into the read beam path and onto the target.  The isolator has a linear polarizer, a polarizing beam splitter, and a retarder functioning together to ensure that at the polarizing beam splitter reflected light is linearly polarized in a direction perpendicular to the incident light.  The combiner is typically an interference filter inclined both to the read and write beam path, which transmits .lambda.1 and reflects .lambda.2. Since the filter strongly alters the polarization state of obliquely incident light, a second interference filter located between the polarizing beam splitter and the first filter is used to compensate for the change in polarization state caused by the first filter and by other elements of the optical system.     - i -
