Patent CA-2027503-A1 (CA)
Inventor: SPELTA ANGELO L
IPC: C08K5/3492
Filed: 1990-10-11
Abstract: ACRYLIC ELASTOMER-BASED POLYMER COMPOSITIONS WITH HIGH FLAME RESISTANCE     ABSTRACT Acrylic elastomer-based polymer compositions characterised by flame retardation and low fume emission are obtained by adding organic or inorganic melamine salts such as melamine cyanurate and melamine phosphate, used singularly or mixed together. These formulations are compatible with the other additives usually used in acrylic rubbers. The flame retardant additives used are effective at low levels of addition, so that the resultant flame resistant elastomer formulations, which are of low fume emission, maintain the main basic elastomer properties, which represent an optimum compromise between elastic properties, mechanical properties and oil resistance under severe service conditions.

Title: Method of making polarization retaining fiber
Inventor: BERKEY GEORGE E
IPC: C03B37/02
Filed: 1991-01-07
Abstract: Abstract of the Disclosure A method of making an optical fiber having an oblong core comprising the steps of depositing layers of core glass particles and cladding glass particles on an enlarged mandrel, removing the mandrel to form a tubular porous preform, consolidating the porous preform to form a dense glass preform, evacuating the central hole of the dense glass preform while stretching that preform to collapse the central hole thereof and form a flattened rod, applying cladding material to the rod, and drawing the resultant composite to form an optical fiber.  To facilitate the flat collapse of the central hole of the dense glass preform and to cause the core to have a large aspect ratio, the inside diameter-to-outside diameter ratio of the dense glass preform should be within the range of 0.3 to 0.9.  For preferred core and cladding glasses, this ratio should be between 0.5 and 0.6.  Also, the mandrel diameter should be at least 12 mm, and it is preferably between 25 mm and 50 mm.

Title: Extrudable polyvinyl alcohol compositions containing thermoplastic polyurethane
Inventor: FAMILI AMIR
IPC: C08K5/05
Filed: 1991-07-05
Abstract: PATENT - 184PUS04287 ABSTRACT An extrudable polyvinyl alcohol composition useful for packaging and molding applications is prepared by melt blending polyvinyl alcohol and thermoplastic polyurethane to provide a product which has low water absorptivity improved impact resistance, and improved low temperature/low humidity tensile properties. Useful extruded articles prepared from such compositions include films and bottles. A method for extruding the polyvinyl alcohol composition comprises: adding sufficient energy to the polyvinyl alcohol composition to both melt it and essentially eliminate the polyvinyl alcohol crystallinlty in the melt, and simultaneously removing energy from the melt at a rate sufficient to avoid decomposition of the polyvinyl alcohol. The thermoplastic polyurethane may be added to the polyvinyl alcohol before the polyvinyl alcohol is melted and its crystallinity eliminated or blended with the thus treated polyvinyl alcohol and then melt extruding the polyvinyl alcohol/polyurethane blend.

Abstract: A housing assembly (100) which uses substantially spherical pieces (rubber balls) (106) for supports (feet). The balls (106) drop into the bottom housing member (104) which has apertures (202) which allow the balls (106) to rest. Each of the balls (106) protrude from the bottom portion of the housing.

Title: Shifted pole single phase variable reluctance motor
Inventor: HORST GARY E
IPC: H02K29/08
Filed: 1992-03-25
Abstract: A hybrid single-phase variable reluctance motor (31) comprises a stator (33) having a plurality of inwardly salient teeth (41A-41D)  terminating at a central bore (37).  The teeth are arranged in generally diametrically opposed pairs of teeth and are generally evenly spaced around the bore.  A phase winding (43) is operatively associated with one pair of the stator teeth.  The winding, when energized, causes a temporary magnetization of the stator teeth.  A rotor (35) is disposed for rotation in the bore and has outwardly salient teeth (45A, 45B) generally diametrically opposed to each other.  A permanent magnet (53) is disposed adjacent the bore at the end of one tooth (41D) of a second pair (41C, 41D) of stator teeth.  One tooth (41D) of the second pair of stator teeth is offset with respect to a longitudinal axis (A1) of the second pair of teeth.  This offset acts to eliminate a stable detent position in which the rotor could otherwise "park" itself when it stops running.  Parking in such a position makes it difficult to restart the motor.
