Title: Converter
Inventor: PIECHNICK JOHN J
IPC: H02M7/757
Filed: 1990-01-03
Abstract: ABSTRACT          The invention relates to a converter which can operate as a rectifier to rectify alternating current into direct current running in one direction  (for example to charge batteries) or a converter where DC (from the batteries) can be converted to AC and supplement AC power, for example to supplement an alternator output in peak load conditions.         The converter comprises a uni-directional electrical energy source (battery) and a bi-directional energy source (small battery bank connected for reverse direction current flow, capacitor or fuel cell) which is capable of initiating an alternating current when controlled by thyristors fired in sequence and with such periods that a sine wave can be simulated.  The switches are controlled by a thyristor trigger logic circuit control unit which may for example be a micro processor.

Title: Friction material and method of manufacturing such material
Inventor: NAKAGAWA MITSUHIKO
IPC: F16D69/00
Filed: 1990-08-31
Abstract: A friction material is so manufactured that a hygienic environment can be maintained while simultaneously reducing the brake noise without reducing the friction coefficient of the brake pads made of the present material. The friction material is granulated or agglomerated by a first binder which binds one or more inorganic substances having a plane netlike crystal structure into granules which are deformed so that the particles have a flat particle orientation in the resulting granules.  The flat particle  orientation  is  achieved  by  the  application pressure and/or heat during the formation.  The granules are then embedded in a second binder forming a fibrous matrix for forming the brake pad material.  The inorganic substance or substances forming the particles having the plane netlike crystal structure, promote a micro-separation in the friction surface in response to the application of a brake force.  The micro-separation effectively prevents brake noise.

Title: Getter structure for vacuum insulation panels
Inventor: KIRBY DAVID B
IPC: B32B7/02
Filed: 1990-11-22
Abstract: A Better structure is provided which can be handled for relatively short periods of time in open atmosphere and yet provides prolonged Bettering action over relatively long periods of time when utilized in a sealed compartment. The Better structure has a thin flexible substrate upon which a Better material is applied. A barrier layer is applied to the Better material to prevent rapid reaction by the Better material with the atmosphere. The substrate or barrier layer is semi-permeable and is selected to provide the desired degree of permeation of the layer to the Better material to result in the action described. Such a Better structure is useful in a vacuum insulation panel, particularly in a Better system in a multiple compartment panel where different Better materials are utilized in different compartments so as to maximize the effectiveness of the use of the Better materials, while minimizing the cost of the Better materials required to provide the desired degree of gas Bettering.

Abstract: Abstract PRODUCTION OF BIOLOGICALLY ACTIVE PLATELET-DERIVED GROWTH FACTOR FROM HIGH EXPRESSION HOST CELL SYSTEMS           A method for refolding recombinant platelet-derived growth factor from a high expression host cell system, such as E  coli, is provided in accordance with the present invention.  The recombinant platelet-derived growth factor is isolated from inclusion body proteins, after which the free sulfydryl groups of the reduced monomeric recombinant protein are blocked.  The blocked recombinant protein can then be brought into a biologically active conformation, without interference from the formation of incorrect disulfide bonds.  Once in a biologically active conformation, the recombinant platelet-derived growth factor may be unblocked to allow the desired disulfide bonds to form, thus locking the recombinant protein into a biologically active conformation.  The present invention also provides a novel mixed disulfide intermediate wherein the free sulfhydryl groups of reduced recombinant platelet-derived growth factor are derivatized to a disulfide blocking agent.

Filed: 1990-12-18
Abstract: Abstract A method for bracing a concrete form assembly by the inter-connection of a first beam member and a second beam member by an inclined beam member.  Each beam member is of a generally rectan-gular shape in transverse cross section and includes a pair of end plates.  An adaptor unit of a right isosceles triangular shape in side elevation is used to connect the inclined beam to the first and the second beam.  The hypotenuse section of a first adaptor unit is mounted on the first beam and the hypotenuse sec-tion of a second adaptor unit is mounted on the second beam.  The locations of attachment are selected such that the distance between oppositely facing side sections of the adaptor units is equal to the length of the inclined beam member, which is inserted therebetween.  Each end plate of the inclined beam mem-ber is bolted to the adjacent side section of an adaptor.
Patent CA-2036743-A1 (CA)
Title: Methods of and apparatus for making coated optical fiber
Inventor: PETISCE JAMES R
IPC: B01J19/12
Filed: 1991-02-20
Abstract: In the manufacture of coated optical fiber, fiber (21) is drawn from a preform (22) and coating with one or preferably two layers (42,44) of light curable coating materials. Afterwards, the coating materials are cured. Increases in manufacturing line speed may be achieved if the cure speed of the coating materials is increased. This is accomplished by the simultaneous application of a magneticfield during irradiation of the curable coating materials to enhance the crosslinking of the coating materials by a free radical polymerization mechanism.  Upon absorption of light, a photoinitiator in each composition cleaves to produce two free radical fragments in the spin paired or singlet state. The magnetic field has the effect of enhancing the production of spin parallel radicals which enhances the polymerization initiation of the coating material, thereby allowing an increase in the manufacturing line speed through drawing and coating apparatus.
