Abstract: A capstan control useful in a recorder reproducer system in the performance of splicing operations, for example. The capstan is controlled for playback and record in response to the error comparison of a tonewheel signal and a selectable one of two other control signals. The control signals are made to be phase correlated to minimize disturbances of the capstan operation when the system is switched between the playback and record modes.

Abstract: A method for producing a kinescope having an image screen and an apertured target mask, the apertures of the mask being temporarily reduced in size for use as a photographic master for producing the image screen. Such reduction in aperture size is achieved by providing the target mask with a coating of a filmforming material which exhibits shrinkage during drying thereof. The coating is comprised of a number of opaque film portions which individually close the mask apertures and preferably are disposed on the aperture walls. The coating is dried so as to remove the central regions of the film portions, thereby providing a temporary mask with light-transmitting corridors in the film portions, such corridors being smaller in cross-section than the mask apertures. The temporary mask is used in screen printing. The shrinkable material is eliminated from the mask, after which the screen and target mask are incorporated into a kinescope.

Abstract: A pair of amplifiers and a load such as a liquid crystal connected between the output electrodes of the amplifiers. In response to one relationship between the input signals to the amplifiers, an alternating turn-on voltage is applied via at least one of the amplifiers to the liquid crystal for causing it to scatter light. In response to another relationship between said input signals, the light scattering produced by the liquid crystal is reduced to a relatively low value.

Abstract: A switch is connected between the output terminal of an amplifier receptive of an amplitude modulated carrier, and a charge storage means. The switch is closed only during each peak of given polarity of an unmodulated carrier of the same frequency as the modulated carrier for permitting the storage means to charge. The time constant of the storage means discharge circuit is sufficiently long so that the storage means does not discharge appreciably during the times the switch is open, whereby a voltage corresponding to the modulation on the carrier develops across the storage means.

Abstract: A synchronous detector includes a differential amplifier section formed from two transistors with input signals applied to their base electrodes and output signals taken from their collector electrodes for application to an included synchronous switching section. A current source section is also included to supply substantially constant quiescent current to each of the transistor emitter electrodes, while a control section is additionally included for diverting some of this current away from the differential amplifier transistors when it is desired to reduce the gain of the detector or inhibit its operation. The electrical control section, however, re-inserts the diverted current into the switching section at a point such that the direct output voltage of the detector does not change as the gain is reduced or as its operation is inhibited.

Abstract: An ultra high frequency (UHF) tuner includes a plurality of tunable transmission lines formed on a dielectric plate. At least two of the transmission lines are tunable over different bands of frequencies and each includes first and second conductive sections, coupled by voltage responsive capacitance devices, disposed on one surface of the dielectric plate, and a conductive ground plane disposed on the other surface overlying the first and second sections. One end of the first section of each of the transmission lines is connected to the ground plane and is shaped to provide tracking as the transmission lines are tuned across their respective frequency bands. An adjustable inductor serially connected with the variable capacitance devices also provides a tracking adjustment between the circuits.

Abstract: There is disclosed the use of a phase diffraction, rather than a plate of diffusing glass, for introducing redundancy into the information beam which is employed together with a reference beam in recording a hologram. The use of a phase diffraction grating eliminates the presence of unwanted speckle noise in the reproduced image of the hologram, which speckle noise is present to a large degree when a small sized hologram is recorded with a diffused light information beam.
