摘要： An analogue to digital converter for logarithmically quantizing an analogue input voltage, which may vary over a wide dynamic range, and providing a representative binary-coded decimal readout. The analogue input voltage is processed through parallel strings of serially connected logarithmic amplifiers, the individual outputs of which are connected to respective threshold detectors at the parallel inputs of a shift register. Upon command, shift pulses are applied to the register to generate a serial output which is applied to a binary counter for readout.

摘要： A frequency synthesizer particularly suitable for VHF applications comprising a pair of variable frequency oscillators adapted to be simultaneously tuned in coarse frequency steps, one of the oscillators being phase locked to a frequency standard, and the second oscillator being controlled by a tunable frequency lock loop referenced to the first oscillator to provide the synthesized frequency output. The tunable frequency lock loop includes a balanced mixer coupled at the outputs of the two oscillators for producing a difference frequency, a frequency discriminator for providing a voltage signal proportional to this difference frequency, a continuously or discretely variable tuning voltage, and a difference amplifier which compares the discriminator output with a selected tuning voltage and provides a difference signal for fine tuning the second oscillator.

摘要： Bistable transistor-transistor logic circuit in which the turnon and turnoff times of a saturated output transistor are decreased by the operation of a bypass circuit which diverts a portion of the output transistor driving current away from the transistor after it has been driven into saturation. The bistable logic circuit is triggered from one state to the other by a clock pulse applied to a control circuit having an input transistor connected directly to the clock pulse terminal and to a capacitance. During the clock pulse the input transistor conducts and charges the capacitance. Upon termination of the clock pulse the stored charge is employed to initiate switching.

摘要： A HERMAPHRODITIC MULTI-CONTACT REED SWITCH INCLUDES A TUBULAR ENVELOPE HAVING A PAIR OF SUBSTANTIALLY IDENTICAL HEADERS SEALED INTO THE OPPOSITE ENDS AND CONTAINS AN INERT ATMOSPHERE. EACH OF THE HEADERS INCLUDES A PLURALITY OF SWITCH MEMBERS HAVING A MAGNETIZABLE PORTION EXTENDING INTERIORLY OF THE ENVELOPE AND IN LONGITUDINALLY OVERLAPPING RELATIONSHIP WITH THE MAGNETIZABLE PORTION OF THE SWITCH MEMBERS OF THE OPPOSITE HEADER. THE LONGITUDINAL

OVERLAPPING MAGNETIZABLE PORTIONS OF THE MATCHING SWITCH MEMBERS OF THE OPPOSING HEADERS HAVE A DESIRED GAP THEREBETWEEN WHICH IS DEPENDENT UPON THE CIRCUMFERENTIAL DISPLACEMENT OF ONE HEADER WITH RESPECT TO THE OTHER.

摘要： The combination of a color television receiver and a display system for presenting slide transparencies, movies or other image mediums upon the color cathode ray tube of the television receiver. The slide or other medium is scanned by a flying spot cathode ray tube which, in conjunction with dichroic mirrors and suitable filters separates the information derived from the scan of the medium into its representative color components, translates the representative color components into processed electrical signals and couples the processed signals directly to appropriate electrodes of the color cathode ray tube. The flying spot cathode ray tube is provided with a fixed focus and has a screen comprised of an admixture of Y3A15012:Ce and Ca2A12SiO7:Ce phosphors in approximately the ratio of 3 to 1 by weight. Also disclosed as an alternate for Ca2A12SiO7:Ce is ZnS: Ag:Ni.
