Title: Feedthrough coaxial cable connector
Inventor: MCMILLS COREY
IPC: H01R24/38
Filed: 1990-06-08
Granted: 1998-09-15
Abstract: A feedthrough coaxial cable connector includes a tubular mandrel body dimensioned to be pressed between a foil-bonded dielectric core and other elements of an outer conductor of the prepared end of the cable. The body has cable engagement surface which defines a knife edge projection therearound for engaging an outer conductor of the cable by creating shear stresses therein without actually shearing the outer conductor. A tubular shank portion extends from the cable engagement surface portion to a radial wall portion, and a jack engagement portion is coaxial about the exposed central conductor. The jack engagement portion achieves a tight friction fit upon a jack and may be formed as an inside compression collet. A radial compression providing structure causes an inside surface region of the outer conductor to bear directly against and bend over the knife edge portion. Preferably, a slideable shell is slideably positionable generally away from a connector end facing the outer surface of the jack to enable the jack engagement portion of the connector to slide over the outer surface of the jack, and slideably positionable toward the connector end so as to radially compress the radially diverging jack engagement portion against the outer surface of the jack to secure the connector thereto. A kit of parts including an expandable installation tool enables proper assembly of the cable connector without special skills or tools.

Abstract: A belt for use on a long nip press for dewatering a fibrous web includes a base fabric, woven from machine-direction and cross-machine directions yarns and taking the form of an endless loop. The base fabric many be woven from monofilaments yarns of a synthetic polymeric resin in either a single- or a multi-layer weave. At least one side of the base fabric, namely, that side which will be on the inside of the belt in its endless loop form, and which slides over the arcuate pressure shoe component of the long nip press during its operation, is coated with a polymeric resin, such as polyurethane, to render it impervious to liquids, especially lubricating oil. The coating is reinforced with a flexible layer of reinforcing fiber which may take the form of a woven sheet or may be in single filament form in single or multiple layers thereof. When in single filament form, each layer includes filaments disposed adjacent and substantially parallel to one another. The reinforcing fiber may be of a synthetic polymeric resin or of metal. In either case, the reinforcement renders the coating less susceptible to cracking and to damage from foreign objects while the belt is in use on the long nip press. <IMAGE>

Abstract: Compounds of formula (I): <CHEM> [in which: R<1> is hydrogen or a hydroxy-protecting group; R<2> is alkyl, alkoxy, halogen, optionally substituted phenyl or optionally substituted phenoxy; R<3> is optionally substituted pyridyl, optionally substituted quinolyl or phenyl group which has a substituent of formula -CYNR<5>R<6>, where Y is oxygen or sulphur, and R<5> and R<6> are each alkyl, aryl or aralkyl, or R<5> and R<6> and the nitrogen to which they are attached together form a heterocyclic group; R<4> is hydrogen or an amino-protecting group; and Z is sulphur or oxygen]; are valuable intermediates in the preparation of carbapenem compounds and retain a desirable configuration during conversion to such carbapenem compounds.

Title: Dynamic focusing electron gun
Inventor: SON WAN-JAE
IPC: H01J29/48
Filed: 1992-08-12
Granted: 1995-06-19
Abstract: The electron gun has a cathode and gratings forming a triode, together with a pair of quadruple pole lenses of opposite polarities. These are associated with three focussing electrodes followed by an acceleration electrode. A dynamic focussing voltage, synchronised with the deflection control signal, is applied to the first and second focussing electrodes. A static focussing voltage is applied to the second focussing electrode. The arrangement operates to alternate the beam between vertically and horizontally stretched forms. The electron gun improves quality of focussed beam as regards vertical Moire effect and horizontal expansion of electron beam spot to produce circular spot over all the display screen including the periphery.
