Patent CA-2065852-C (CA)
Title: Pneumatic-electrical quick disconnect connector for a plasma arc torch
Inventor: GRATZIANI ISAAC
IPC: H05H1/34
Filed: 1990-07-20
Granted: 1996-03-26
Abstract: A quick disconnect connector for both electrical power and gas flow to a plasma arc torch has a plug that includes at least one pin contact and a mating receptacle that includes at least one socket contact that receives the pin contact axially.  Both contacts have a central axial passage that conducts the gas flow at a sufficient rate to cool the contacts when they are conducting a large heavy operating current, typically 20 to 1,000 amperes, D.C.  For high voltage operation, each contact is closely surrounded by a barrier sleeve of a dielectric material which is supported in an insulating body filling the plug or receptacle.  The sleeved contacts are mounted to pivot independently of one another about a central mouning boss for self-alignment on mating.  O-rings seal the sleeves to the insulator bodies to restrict the gas to a connection zone of the connector.  The sleeve barrier axial length and that of the insulating bodies exceed the minimum tracking distance at the high voltages (typically 5 KV) and high frequencies (typcially 2-3 mHz) associated with start-up of the torch.

Title: Fabric for airbag
Inventor: SWOBODA PETER
IPC: B60R21/16
Filed: 1992-04-14
Granted: 2003-02-18
Abstract: There is described a synthetic yarn fabric for the gas-releasing part of an airbag. The synthetic yarn is a syn-thetic high-tenacity multifilament yarn having a filament linear density of less than 4 dtex and a yarn count within the range from 250 to 550 dtex. The fabric itself is in a crepe or modified huckaback weave. In contradistinction to the conventional polyamide fabrics, it is uncoated and is preferably woven from unsized yarns. The fabric need not be calendered. It has been found that this fabric of fine-filament, high-tenacity polyester yarn, although uncoated, does meet the airbag fabric requirements such as readily preselectable air permeability, low fabric weight and low fabric thickness and also high fabric strength.

Abstract: A very high speed adiabatic face milling machine whose configuration and operation provide a highly efficient machining process suitable for production manufacturing conditions. The milling machine preferably operates at speeds of approximately 15,000 sfm and at efficiencies of approximately 7 cubic inches per minute per horsepower. The preferred milling operation is conducted without the use of cooling liquids, instead employing a chip removal system which enables the milling machine to operate truly adiabatically such that no heat is transferred to the workpiece or the cutter. The efficiency of the chip removal system is such that chip recutting is nearly eliminated and tool life is improved. The milling machine also includes an improved cutter structure, fixturing, and transfer devices.

Abstract: A method and apparatus for coating a metallic substrate with an oily substance.  Use is made of a support member having a ceramic coating comprising an oxide ceramic material, onto which is applied the oily substance  to  form  a  film  of  the  oily  substance uniformly covering the surface of the ceramic coating, the film of oily substance breaking down into micro-droplets having substantially uniform size and distribution.  The  micro-droplets of oily substance are thereafter transferred onto a surface of the metallic substrate without substantially altering the size and distribution of the micro-droplets, thereby coating the surface  of  the  metallic  substrate  with  the  oily substance.  The  invention  is  particularly useful  for coating  the  positive  electrode  of  a  high-speed electrocoagulation printing apparatus with an olefinic substance containing a metal oxide.

Abstract: A parts feeding apparatus includes a plurality of cassettes respectively holding therein rows of parts of different types and removably attached to a plurality of parts supply openings arranged at predetermined angular intervals along the peripheral edge of a rotating circular plate.  The circular plate is intermittently rotatable so that a selected one of the parts supply openings and the cassette attached thereto are positioned relative to the inlet opening of a parts delivery chute.  An open lower end of the cassette is opened and closed at predetermined time intervals by a reciprocating slide plate member disposed in a parts supply unit.  The parts feeding apparatus thus constructed is compact in size and simple in construction. Since the cassettes are arranged on the same circumference on the circular plate, the parts to be fed can be automatically and smoothly changed or switched from one type to another.  Thus, the apparatus is readily adaptable to the production of articles of different types to be manufactured in relatively small lots or in relatively large lots.
