Abstract: ABSTRACT OF THE DISCLOSURE           The basic module of a microwave Travelling-Wave Hybrid Junction amplifier (TWHJ) consists of a hybrid junction (0°, 180° or 90° hybrid) combined with an appropriate phase-shifting element (.pi./2 element is needed for 0° and 180° hybrids and no element is needed for a 90° hybrid) and three negative conductance circuits terminating three ports of the modified hybrid while the fourth port serves as an input-output port.  Because of proper stabilization and matching, the nega-tive conductance circuits are not oscillating but are acting as reflection type amplifiers.  Any RF energy applied to the input port of the hybrid is multiply reflected while travelling through the hybrid giving rise to amplified RF energy emerging from the input port of the hybrid junction.  Under ideal con-ditions, the power amplification of the TWHJ amplifier is the product of the power amplifications of individual negative conductance circuits and the saturated output power of the amplifier is equal to the saturated output powers of the circuits adjacent to the output port.  The TWHJ amplifier can be extended in a modular fashion to any number of negative con-ductance elements to achieve the desired power amplification and saturated output power.

Inventor: MARTIN PATRICK H

Granted: 1981-12-01
Abstract: ABSTRACT OF THE DISCLOSURE               Hydrophobic, thermoset resins having highly desirable properties in coatings applications can be prepared from water-thinnable base salts of novel acidic, polymeric esters made by reacting orthophos-phoric acid with hydrophobic, nominally-difunctional polyether epoxide compositions having average epoxide equivalent weights of from 172 to 5500.  The base salts are thermally decomposable to yield resins which are rapidly self-converting if methylol or alkoxymethyl substituted epoxides are included in said compositions.           The functional groups responsible for water solubili-sation are utilized in curing of the resins.  The inven-tion provides a method of utilizing hydrophobic, high performance polyether epoxide type polymers in aqueous coating systems having relatively high abilities to wet non-polar surfaces.  Wetting properties of the systems may be varied by choice of the organic radicals included in one or more of the epoxide components of the poly-ether epoxide composition employed.

Abstract: ELONGATE ELECTRICAL CONNECTOR RETAINING DEVICE       Abstract of the Disclosure An electrical connector retaining device for retaining the male and female members of an elongate electrical cable connector in their mated positions is disclosed. The retaining device includes a semi-resilient strap and a rigid frame. The strap includes a planar region and one or more anchoring prongs having bullet shaped ends integrally formed with the planar region and projecting outwardly from one edge thereof. Extending obliquely outwardly from the edge of the planar region opposed to the prong edge is a flange. The flange is integrally formed with the planar region and includes a plurality of ridges that lie parallel to the edge from which the flange extends. The rigid frame may be integrally formed in the housing or chassis of an electrical subsystem, or as a separate item. The rigid frame includes an aperture in which one element (e.g., male or female) of the connector is mounted. That element is attached to the rigid frame. Located in the rigid frame, along one of the longitudinal sides of the aperture are holes adapted to receive the anchoring prongs. On the opposite side of the aperture is a slot and one or more cross-bars adapted to receive and interact with the ridges formed in the strap flange when the strap is wrapped over the assembled connector. The cross-bars may be located in an integral flange lying transverse to the plane of the portion of the rigid frame supporting the connector element. A multitude of cross-bars form a ladder arrangement that interacts with a number of ridges, rather than a single ridge.
