Abstract: A weft knitted double-jersey fabric is knitted in a construction of repeating groups of courses in which some courses have loops pulled to both fabric faces and some courses have loops pulled to one fabric face and are transversed by yarn regions which extend across at least two wales and up to seven or more wales.   The yarn feed to the needle beds of the knitting machine is limited to no more than 4.0 cm/cm of bed length over which the fabric is knitted in courses in which loops are pulled to both faces of the fabric and to no more than 2.0 cm/cm of bed length, preferable no more than 1.8 cm/cm, in courses in which loops are pulled to one face of the fabric.   The fabric has an extensibility of no more than 12% in wale and course directions. It is knitted with a high count yarn of 550 to 850 decitex which may be an air-textured polyester yarn.   It is suitable for use as upholstery fabric particularly in the form of a vehicle seat upholstery cover which may be shaped to fit the seat in the knitting process.

Patent CA-2064868-C (CA)
Title: Combustion apparatus
Inventor: MORITA SHIGEKI
IPC: F23D17/00
Filed: 1991-06-27
Granted: 1996-04-09
Abstract: A combustion apparatus comprises a mixture feeding pipe through which a mixture of pulverized coal and combustion air flows.  The mixture is injected into a furnace through the mixture feeding pipe and then ignited.  A radial outwardly flared flame maintaining ring is provided at the tip end of the mixture feeding pipe.  The flame maintaining ring is under a reduction atmosphere and exposed to high temperatures due to radiant heat from the furnace.  Therefore, there is a possibility of burnout of the flame maintaining ring or growth of slag on the flame maintaining ring.  In order to prevent this, a projection is disposed to extend into the furnace beyond the flame maintaining ring so as to shut off radiation from the inside of the furnace to the flame maintaining ring adequately, thereby suppressing an excessive temperature rise.  Combustion air flows along the surface of the projection so as to locate the projection under an oxidation atmosphere.  A pulverized coal/air separating member extends through within the mixture feeding pipe.  A portion where separation of the flow is forcibly occurred is formed locally in a conical end portion of the pulverized coal/air separating member.  It is therefore possible to effect a combustion in a stabilized manner as a whole regardless of the unit capacity and load of the combustion apparatus.

Title: Center sill with short yoke member
Inventor: KAUFHOLD HORST T
IPC: B61G5/02
Filed: 1992-12-09
Granted: 1994-09-06
Abstract: The present invention relates to a railway car coupler arrangement whereby a standard yoke, follower, and draft gear are removed from the center sill and replaced with a short yoke member, a spacer block member and slackless drawbar arrangement, namely, a pocket casting wedge shim, and follower, easily converting the coupler arrangement to a drawbar arrangement without modifying the center sill.  The short yoke member, spacer block and slackless arrangement fit exactly within the space formerly occupied by the draft gear pocket casting.  The drawbar arrangement maintains the same degrees of angling freedom as the coupler since the drawbar is connected and pivoted from the same pin location as when the coupler was installed.  The short yoke member is also designed to more uniformly distribute draft loads to the center sill by transferring forces from the connecting pin into the short yoke member, which in turn transfers those forces into abutting center sill front stops, left intact from the coupler arrangement.  The present invention further provides a quick method for converting a broken coupler to a drawbar arrangement for towing hack to a repair shop.

Compressive forces exerted against the tubular-shaped body when positioned against the electrically-conductive cover (392) causes seating of the tubular-shaped body against the electrical-ly-conductive cover. First and second claw arms (148, 154) extend beyond a side surface positioned in opposi-tion to the seating surface (136) of the tubular-shaped body. The claw arms are affixed about an edge portion of the substrate (398). The side surface (142) positioned in opposition to the seating surface abuts against the electrically-conductive edge portion of the substrate to be electrically connected therewith.
