Abstract: ABSTRACT          This invention relates generally to electrical connectors and more particularly to improved modular inter-face connectors and connector assemblies incorporating such modular connectors. A continuing problem with present con-nectors and connector assemblies is that a wide variety of assembly component parts are necessary to meet different connection requirements inasmuch as different connector assemblies, such as adapters, bridging assemblies, data sets, junction assemblies, and the like, having non-inter-changeable components are required for various different connection purposes.  The present invention is designed to provide a slidingly mountable modular connector capable of easy installation and replacement coupled with reliable operation.  The modular connectors of the invention include improved mounting structures which permit each connector to be slidably mounted on a support member in at least two alternate orientations and to be retained at any position between two spaced shoulders of the support member.  In addition, the modular connector is preferably an integrally molded plastic unit configured to permit its fabrication in a single-action mold.  In one embodiment, the interface con-nector further includes a removable comb member which separates and aligns the active portions of the connector contact elements and prevents access through the entrance aperture of the connector to the free ends of the contact elements.  In another embodiment, the interface connector includes an integral comb structure and embossments disposed on the connector housing for engaging and mounting at least one bus bar member to the housing adjacent the comb structure.

Abstract: Abstract of the Disclosure A solution  process  for  the preparation  of  high molecular weight homopolymers of ethylene and copolymers of ethylene and C3 - C12  .alpha.-olefins is disclosed.   The process involves feeding monomer,  a particular coordination catalyst and hydrocarbon solvent to a reactor, polymerizing the mono-mer at a temperature of 105-320'C and recovering the polymer. The catalyst is obtained by combining solutions of titanium tetrahalide and of organoaluminum compound at a temperature of  less  than  30°C,  heating  the  resulting  admixture  to  a temperature of 150-300°C  for a period of 10 seconds to  10 minutes and combining the thus heat-treated mixture with  a solution of an organoaluminum compound.

Abstract: ABSTRACT           A T-carrier digital test system which actively moni-tors each T-carrier wire pair on a time division multiplexing basis while either live communications or test signals are on the line, and determines from the monitored data whether an incipient or hard failure of the line exists.  It achieves this result by utilization of interacting devices called Scanners and Scanner Controllers.  Each Scanner is housed in a repeater case and is connected to and monitors the output of each regenerative repeater in that case.  The Scanner also connects to a fault line which runs in parallel to the T Carrier wire pair and acts as the communications media and power path between several Scanners and the telecommunications facilities at each end of the cable pair.  The Scanner Controller is housed in one of the telecommunications facilities and controls and determines what tests the Scanners should perform, synchron-izes the Scanners, interprets the types of errors detected by the Scanners and patterns the errors to locate a defective T-Carrier wire section and/or marginal or defective regenerative' repeater.  Test results may be displayed on a cathode ray tube and/or printer.

Abstract: ABSTRACT OF THE DISCLOSURE       The heat accumulating material of this invention comprising the three components calcium chloride (CaCl2), urea [CO(NH2)2] and water (H2O) can have varied temperatures of heat accumulation and heat release between 15°C and 29.5°C by varying the relative proportions of said three components, and also has a large latent heat.  Hence, it is advantageous for use as a heat accumulating material for air conditioning.  Moreover, by adding BaFeO3-x (0?x?0.53) as a nucleating agent to the above-mentioned composition, supercooling can be greatly decreased and wider application of this heat accumulating material becomes possible.

Abstract: Abstract The present invention provides a mechanism for cen-tering the screw base of an incandescent lamp in the socket of a porcelain base having thread segments molded directly onto the inner wall of the socket.  A bias contact is provided at the inner wall of the socket for centering the base of the lamp by biasing it in two lateral planes along two planar faces, the pressures from the two faces being perpendicular to the faces and thus directed toward the axis of rotation of the screw base.          Thus, the base is continuously centered, so that its center contact makes electrical contact with a centrally located bias contact mounted in a pocket formed in the center of the closed end of the socket.  The bias contact and the centrally located contact are in turn connected to electrical leads which extend through the closed end of the socket.

Title: Adjustable coring circuit permitting coring extinction
Inventor: SHANLEY ROBERT L IIUS
IPC: H04N5/44
Filed: 1983-03-07
Granted: 1985-08-06
Abstract: ABSTRACT Adjustable coring circuit includes linear amplifier and multistage limiting amplifier responsive to input signals from a common source. Limiting amplifier includes an input stage receiving operating current from a first current source transistor, in cascade with an output stage receiving operating current from a second current source transistor. Cored signal, corresponding to the difference between a linearly translated version of the input signals and a doubly clipped version thereof, is developed by a signal combiner responsive to outputs of both amplifiers. Base-emitter paths of the two current source transistors are connected in series across a common bias source. The base electrodes of two control transistors, of mutually opposite conductivity types, respond to variations of common coring level control voltage. Collector-emitter path of one control transistor shunts base-emitter path of first current source transistor. Emitter-collector path of other control transistor, which shunts the common bias source, is nonconducting over major portion of variation range of coring level control voltage.

Abstract: Abstract Production of ammonia by the sequence of steam hydro-carbon primary reforming, secondary reforming with air, carbon monoxide shift conversion, carbon oxides removal and catalytic ammonia synthesis is improved by using oxygen enriched air at secondary reforming and/or by operating the reforming steps so that 5 - 15% by carbon atoms of the starting hydrocarbon is not reformed but is purged from the synthesis.  The oxygen enriched air can be the by-product of a simple air separation plant producing nitrogen, and the nitrogen can be used to air start-up or shut-down of the process or to keep the process plant in a hot stand-by condition.
