Title: Method and apparatus for connecting branch circuits to cores of a live electrical cable
IPC: H01R9/03
Filed: 1983-06-07
Abstract: Method and apparatus for connecting branch circuits to cores of a live electrical cable include placing a plurality of contact pieces individually in position in a common predetermined cable cross-sectional plane. The branch circuits may be connected to the contact pieces before or after such placement. The contact pieces each have contact feet which include contact blades or like arrangements. The contact feet can be inserted into a dual trough-like spacer piece placed between the cable cores. A multi-piece clamping ring maintained in an assembled condition by tension bolts is positioned to enclose or envelop the contact pieces. During the process of tightening the tension bolts, pressure pieces exert pressure on the cable cores so that the cores are pressed against the adjacent contact pieces. This results in the contact blades penetrating the core insulation to establish physical contact with the cable.

Title: Recording and reproducing system for color video signal
IPC: H04N9/83
Filed: 1970-12-31
Abstract: A composite color video signal may be magnetically recorded by separating the luminance and chrominance signals, and frequency modulating the former on a carrier, and frequency shifting the latter such that the bands of the frequency-modulated luminance signal and the frequency-converted chrominance signal are substantially not overlapping. The two signals are then combined and magnetically recorded with the frequency-converted chrominance signal added to the frequency-modulated luminance signal. To avoid a beat interference between the second harmonic of the carrier of the frequency-converted chrominance signal and the luminance signal, the system is designed to interleave the second harmonic of the carrier of the frequency-converted chrominance signal with the luminance signal. By avoiding the beat interference the amplitude of the frequency-converted chrominance signal relative to the amplitude of the frequency-modulated luminance signal can be made large with resulting good signal-to-noise ratio of the chrominance signal.

Title: Electrical contact in semiconductor devices
IPC: H01L21/3205
Filed: 1985-08-29
Abstract: Contacting an underlying region (e.g., doped silicon) through an access hole in an overlying dielectric layer (e.g., p-glass) formerly required flowing the dielectric to smooth the edges of the hole, so that aluminum would deposit smoothly into the hole. The present technique smoothes the side of the hole by forming a smoothing region on the sidewall. Improved aluminum coverage results, as well as allowing a smaller contact head, if desired. Improved contact resistance can be optionally provided by depositing a more conductive layer on the underlying layer prior to forming the sidewall.

Abstract: PURPOSE:To produce the objective product in high yield, in the chemical dehydration reaction to produce a high-boiling compound having higher boiling point than an organic solvent, by carrying out the reaction while disilling out the produced water together with the organic solvent by the vapor-recompression process. CONSTITUTION:A reaction for producing a high-boiling compound having higher boiling point than the organic solvent used in the reaction and accompanying the by-production of water, e.g. ketalization, esterification, alcoholate-formation reaction, etc., is carried out while distilling out the produced water together with the organic solvent by the vapor-recompression process. In the above process, the reaction raw materials containing the organic solvent are charged to the reactor 1 and circulated with the circulation pump 2 through the evaporator 3. The reaction is initiated by supplying steam, etc. to the jacket of the evaporator 3, thereby raising the temperature of the circulating liquid. The organic solvent and a part of the produced water are evaporated and separated into gas and liquid with a demister 4. The vapor is compressed with the compressor 5, sent to the jacket of the evaporator 3 to transfer the heat to the evaporator, and treated with the dehydrator 6. The separated organic solvent is reused.
