Abstract: ABSTRACT:          "Device for interactive video playback."     A device for interactive video playback is based on a playback apparatus for video discs. Such a video disc contains invariably stored video information and possibly also audio information. The various playback and addressing modes can be activated by operation of buttons. The infor-mation read is directly suitable for playback on a tele-vision screen. The playback apparatus is made suitable for executing these playback and addressing modes also under the control of selection signals received from a computer. There is also provided an extraction element for extrac-ting the frame numbers from the information read and for supplying these numbers as data to the computer. The com-puter furthermore comprises a read/write memory for the storage of the information of alphanumerical characters and of selection signals for the playback apparatus. In some cases, the latter signals are activatable only by a ful-filling signal. The computer also comprises an output for said alphanumerical characters as additional display in-formation. There is also provided a keyboard. This key-board is suitable on the one hand for inputting instruc-tions for the computer which are expressed in a higher programming language in order to modify the program to be executed by the computer. It can also be used for producing a fulfilling signal for activating a selection signal read from the read/write memory.

Abstract: PHN 9686                 10                       15.8.80 ABSTRACT: Variable-gain amplifier stage equipped with field-effect transistors.     A variable gain amplifier stage equipped with field-effect transistors. Said stage comprises two field-effect transistor connected as a differential pair, using a controlled tail-current source as gain control, so that a slope control is obtained. The transistors connected as a differential pair each have a field-effect transistor operated in the triode region as a load, so that the sig-nal resistance of said transistors is a function of the tail current. As a result of this, the gain factor of the amplifier stage is determined by the slope of the ampli-fier transistor as a function of the tail current and by the signal-current resistance of the load transistors as a function of the control current, which over a compara-tively wide range of tail current yields a substantially linear relationship between the gain factor expressed in decibels and the tail current.

Abstract: Abstract This disclosure deals with an electromagnetic ram actuator, the electromagnet of which consists of two symmetrically designed magnet-izable yoke halves.  The facing pole ends of the yoke halves are in each case essentially semicircularly recessed, forming two aligned essentially circular operating gaps.  Between the operating gaps a ram is arranged which is shiftable in The direction of their line of alignment and whose cross-section is adapted to the area of the operating gaps.  The ram comprises two armature disks of magnetizable material and a spacer element arranged therebetween consisting of predominantly non-magnetizable material.  One armature disk is associated with each operating gap.  The armature disks are geo-metrically designed in such a manner that their volume is of the order of the operating gap volume.  In the starting position of the ram the armature disks are positioned in front of the operating gaps of the electromagnet in its non-excited state.  Upon excitation of the electromagnet, they are pulled into its operating gaps, being accelerated in the process.  The ram actuator is particularly suitable for use in impact printers.

Abstract: Abstract In apparatus for pouch forming, filling and sealing, a printed web, having registration marks at locations where transverse seals are to be formed in order to form a pouch, is fed through drive rolls; over a plow which forms a longitudinal fold in the web; around a sealing wheel having lands which the web con-tacts to form transverse pouch-forming seals; around a filler where product is poured into the pouches; past a top sealer and a cutoff where the pouch forming is completed and the individual pouches are severed by knives.  A photoelectric scanner scans the registration marks and produces a pulse when each passes the scanner. An electric eye cooperating with a disk driven by the machine determines the position of the sealer lands. A tachometer driven by the machine produces pulses proportional to the speed of the machine.  A stepping motor continuously drives the drive rolls.  The outputs from the photoelectric scanner, the electric eye and the tachometer are used in association with a microprocessor for controlling the position of the registration marks with respect to the lands so as to form transverse seals on the pouches between the printed matter associated with each pouch.

Abstract: PLASMA DISPLAY PANEL DRIVE ELECTRONICS IMPROVEMENT                 Abstract of the Invention Voltage pulser circuits are utilized to selectively, alternatively supply high voltage to, or ground the high voltage input of plasma panel driver chips.  High voltage is supplied to a driver chip only when the driver chip must perform an addressing pulse.  The grounding operation, which is induced by shorting the high voltage input of a driver chip to the ground input of the chip, greatly reduces the amount of power which must be dissipated in the driver chip.  The use of the voltage pulser circuit also allows full slew rate control of the output pulse which the driver chips supply to the plasma panel.

Abstract: VENT DAMPER WITH EMERGENCY MANUAL OVERRIDE     ABSTRACT OF THE DISCLOSURE           In the event of a malfunction of the unit, the damper plate may be moved to and locked in the open position, to permit the furnace to operate.  With the plate locked, the motor would normally run continuously, even when the furnace was not operating.  This is because the closed position of the plate, necessary to turn off the motor, cannot be reached.  A slip clutch, located between the motor shaft and the plate, has parts which slip relative to each other when the motor is running but the plate is locked.  The contours and biasing of the parts causes one part to move a limited distance, in a direction opposite to normal.  The motor is stopped in response to this oppositely directed movement.     A bent portion of the plate positioning shaft is freely received in a recess elongated in and laterally spaced from the motor shaft for self-alignment and to permit the oppositely directed movement necessary to stop the motor.
