Abstract: A constant phase diode limiter has a pair of oppositely poled diodes in series between the primary of an output transformer and an input terminal. The junction of the diodes is connected to a voltage source through a resistor and inductor. A capacitor having the same value as the capacitance of each of the diodes when nonconducting is connected between the input and the secondary winding of the output transformer. The secondary winding of the output transformer is connected in series between the output terminal and the latter capacitor.

Abstract: A downlink dish receives television signals from a remote location transmitted by satellite. Satellite receivers demodulate these received signals and normally transmit them through a switch to modulators which modulate respective carrier signals to retransmit the remote program video signals over a cable to subscribers. The switch also transmits the demodulated signals to tone monitors that detect a tone indicating the beginning of a spot message interval. A computer control responds to these detected signals to enable one or more video tape machines to deliver recorded spot messages to a time base corrector that also receives portions of the program video signal adjacent the spot message interval from the switch. The time base corrector delivers the time-base-corrected video signals through the switch to the modulators for modulating a selected carrier signal with program video signals and spot message signals without flicker.

Abstract: The subject invention is directed to a coaxial connector or interseries adapter comprising of at least one metallic center conductor, an insulating captivation bead surrounding said center conductor and at least one metallic coaxial sheath disposed in coaxial relationship to said at least one center conductor. The captivation bead imparts a dramatic increase in mechanical strength to the connector or adapter preventing axial or radial movement of the center contact, in relation to the outer contact, when differential forces are applied between the center and outer contact. The captivation bead in the coaxial connector or adapter can be matched to achieve a low VSWR. Surprisingly the captivation bead allows a dramatic increase in power handling capability.

Abstract: A cable television system includes a minicomputer that responds to signals from viewers desiring to see particular television program material to provide a schedule video signal that is broadcast over a program schedule channel carrying a video signal representative of television programs to be broadcast, the time of broadcast and the channel where broadcast. The computer also provides selecting control signals that causes a particular television signal source, such as on a video tape cassette, disc or film, to provide a video signal that is coupled by a video switch controlled by switching control signals from the computer for modulating a television transmitter associated with a channel selected for broadcasting the selected television program material. A television signal combiner combines the signals from the different television transmitters for broadcast over a cable to the remote receiving locations.

Abstract: A diode modulator type electrical mixer network has at least two hybrids of transmission line construction, interconnected by means of two sets of four or more diodes arranged in bridge circuit configurations. The interconnecting configuration provides a novel means of local oscillator injection that allows the mixer to operate in a mode that substantially reduces the mixer's susceptability to effects caused by reflective external source and load termination impedances differing from an ideal 50 ohm nonreflective condition.

Abstract: A component carrier for supporting a small precision electronic component with fine leads includes a pair of like generally J-shaped thin plates for mating relationship with each other in slightly overlapping relationship to define an opening accommodating the component with a number of parallel channels from the opening to the outside for protectively accommodating the component leads. These channels are formed by a series of partially overlapping staggered openings from opposed sides of the thin surface that define parallel channels between the closely adjacent opposed surfaces that snugly accommodate the component leads.

Abstract: A horn for radiating circularly polarized energy includes a rear launcher section commencing with a double-ridged cross section and ending at the horn flare with a square cross section with the plane of polarization so that the wave excited in the square cross section is along a diagonal of the square. The horn flare section opens up to a dimension of approximately 70% larger than the square throat dimension to narrow the elevation beam. A dielectric slab oriented in the horizontal plane is seated in the flare section for introducing a frequency-varying differential phase shift between orthogonal modes for effectively compensating for the inherent phase shift in the flare. Refracting lenses that are half-cylinders having a diameter of about 25% of the horizontal aperture dimension with their axes aligned vertically are located close to the vertical aperture edges for refracting the energy at the horn edges into the region between 30.degree. and 60.degree. from the horn axis.
