Abstract: An encoded binary signal which is self clocking and absolute phasing is provided by a method which provides a first pulse manifesting a first binary value having all transitions of the same predetermined polarity at bit interval boundaries and transitions of the opposite polarity intermediate the bit interval boundaries. A second pulse is provided having no transitions intermediate the interval boundaries and at least one transition in coincidence with one interval boundary thereof having the same predetermined polarity, the second pulse manifesting a second binary value. The presence or absence of a transition within a bit interval determines the binary value manifested by the pulse occuring in that interval and the time of occurrence of all transitions of the predetermined polarity identifies the time of occurrence of the interval boundaries of the signal.

Abstract: The technique of tuning a maser at a high rate is used for improving radar receivers and communication receivers. In radar receivers, the maser which is used as the first stage thereof, is detuned from the radar transmitter frequency during the time interval in which each exploratory pulse is being transmitted. This avoids the need for high power transmit-receive isolation means providing 80-90 db. of attenuation normally required in radar systems employing masters. In communication receivers a single maser may be time divided between a plurality of different high gain narrow pass band channels.

Abstract: A vertical phase synchronization system for a television receiver develops vertical deflection frequency signals by employing a resetable frequency divider circuit to count down clock pulses having a frequency twice the horizontal deflection frequency. The resultant internally generated vertical signals are compared with received external vertical synchronization signals. If a phase error exists, a pulse width detector to which external sync pulses subject to noise are applied, is activated. When activated, the pulse width detector develops a reset pulse for the frequency divider to lock the phase of the internally generated vertical signals with external vertical sync in response only to a pulse of the requisite vertical sync pulse duration, thereby providing noise immunity for the system.

Abstract: Pending U.S. Pat. Applications Ser. Nos. 103,713 and 121,250 disclose high voltage protection circuits which change the frequency of the horizontal oscillator of a television receiver in response to an indication of increase in the ultor potential developed for its picture tube which could cause danger of Xradiation. Whereas the circuits of such disclosures operate to change a voltage in the horizontal oscillator to which a capacitor is required to charge in establishing the oscillator frequency, the circuit of the instant invention operates to vary a resistance which, together with a capacitor of this type, sets the time constant which determines such frequency.

Abstract: A sheet metal waveguide includes a pair of sheet metal channels with each channel having a double bend or fold along each of two substantially parallel leg sections. The channels are arranged relative to each other such that a portion of a leg suction of one channel overlaps a portion of a leg section of the other channel in a manner to form a waveguide having recesses on opposite broad walls thereof suitable for receiving and holding a dielectric body therebetween. The ends of the leg sections of one channel are clipped and thereby held within a bend or fold in the leg sections of the other channel.

Abstract: Disclosed is an alarm circuit for detecting change in the condition of an ambient being monitored. Two voltage dependent regenerative switches are connected in parallel with a power supply that provides an intermittent voltage. A condition sensitive element is coupled to the circuit to cause one of said regenerative switches to be in a conducting state as a function of the condition being monitored. When a change occurs in the ambient, the other regenerative switch becomes conductive thereby activating an alarm device which is coupled thereto.

Abstract: A photoconductive-ferroelectric device is employed as an erasable storage medium for recording and reading light patterns. The ferroelectric material may be a bismuth titanate crystal and its polarization pattern (corresponding to the recorded light pattern) is read out by directing linearly polarized light at the ab-face of the crystal, at an angle to the c-axis of the crystal and preferably perpendicular to the b-axis of the crystal. With proper choice of the direction of linear polarization, the incident light is phase delayed different amounts in the differently polarized regions of the crystal and this difference in phase may be detected and employed as the basis for reconstructing the light pattern. Operation in this way is found to provide substantially greater readout efficiency than has been available heretofore.
