Title: Oxygen/fuel firing of furnaces with massive, low velocity, turbulent flames
Inventor: SHAMP DONALD ELLSWORTH
IPC: C03B7/06
Filed: 1993-09-13
Abstract: An oxygen-fuel firing system for a furnace comprising separate, spread apart nozzles for introducing gaseous streams of oxygen and fuel into the furnace at spaced apart locations. The gaseous streams merge within the furnace away from the furnace walls and crown. Thus, the main combustion within the furnace takes place in the central portion of the furnace where a broad flame cloud is created. The broad flame cloud provides a more uniform temperature profile within the furnace for a more efficient processing of materials being melted in the furnace.
Patent CA-2124884-A1 (CA)
Inventor: DORMER MICHAEL WILLIAM
IPC: G05F1/565
Filed: 1994-06-01
Abstract: A voltage regulator apparatus for regulating an unregulated voltage supply to in turn provide a regulated voltage. The voltage regulator apparatus includes a pass device, which has a control port, passes a portion of an unregulated voltage through to the regulated voltage output. The apparatus also includes a DC amplifier which provides a large closed loop gain to the regulated voltage output which is fed back to the pass device control port.      The portion of the unregulated voltage passed to the regulated voltage output is a function of the output of the DC amplifier. The apparatus finally includes a voltage reference which provides a reference voltage to the DC amplifier. The DC amplifier voltage reference and pass device control port all draw the same operating current from the unregulated voltage supply. Thus, creating a sharp low-drop out characteristic for the voltage regulator apparatus.

Title: Tufted carpeting having an improved backing and process of making same
Inventor: BOVA PATRICK
IPC: D05C17/02
Filed: 1994-08-29
Abstract: A method for making tufted carpet, as well as the tufted carpet made by this method, are provided.  Pile yarn fibers are tufted into a tufting backing, which is composed of a primary backing, a secondary backing, and an elastomer sandwiched between the primary and secondary backings.  In another embodiment, the tufting backing comprises a primary backing and an elastomer applied to the primary backing, but does not include a secondary backing.  In a preferred embodiment, the elastomer is applied to the primary backing in a non-contiguous form whereby voids are provided within the arrangement for the tufting backing to be tufted without the primary backing fibers being immobilized.  After the pile yarn fibers are tufted into the tufting backing, the elastomer is heated such that it softens, allowing the elastomer to flow in and around the pile yarn fibers.  The elastomer may then be cooled, thereby hardening the elastomer and bonding the pile yarn fibers to the primary backing.

Title: Process for preparing high-molecular-weight polyesters
Inventor: HOMANN WALTER K
IPC: C08G63/54
Filed: 1994-09-02
Abstract: ABSTRACT:         A process for preparing high-molecular-weight polyesters is disclosed.  The process comprises reacting an aromatic dicarboxylic acid with a mixture of alkanediols and alkenediols, with substantial exclusion of oxygen and in the presence of a catalyst.  According to the invention, the polycondensation step is continued until a viscosity number in the range from 50 to 140 cm3/g is achieved and the polyester so obtained is subsequently subjected to a solid-phase postcondensation step, until the required viscosity number is achieved.  The process of the invention makes it possible to obtain quickly and economically small amounts of high molecular weight polyesters, from which films, profiles, hollow articles, shaped parts etc. can be produced by injection moulding.

Title: Method for rendering waste substances harmless
Inventor: RITTER ROBERT A
IPC: B09B3/00
Filed: 1995-03-21
Abstract: A method is provided for the treatment of hydrocarbon-contaminated soil by chemical hydrolysis and/or oxidation of the hydrocarbons in the hydrocarbon-contaminated soil. The method includes conditioning lime with a particularly-recited liquid mixture of fatty acids hydrophobizing agent. Such lime, either before the conditioning treatment, or after such treatment, is preheated to a temperature of 50°C to 80°C to provide conditioned lime.  Such conditioned lime is  intimately  blended  with  physically-preconditioned, moist, hydrocarbon-contaminated soil, under conditions of high shear, the degree of blending being at least near microscopic level.  A charge of such blended conditioned lime/soil mixture  is  conveyed to an enclosed reaction vessel and hydration of the lime in the blended conditioned lime/soil charge is carried out by the addition of water and/or steam and, substantially simultaneously, air and/or oxygen-enriched air, thereby to effect a flameless, inter-mediate-temperature oxidation of the hydrocarbons or of their hydrolysed degradation products.   The heat of the hydration reaction is retained within the vessel.   The oxidized products are passed through the blended condi-tioned lime/soil charge at a progressively increasing tem-perature.  Decontaminated soil product is discharged from the reaction vessel and may be cooled to a temperature below 100°C, and then passed through a zone where it may be sprayed with a surfactant.  The decontaminated soil product is passed to a blender where it is mixed with sufficient water to provide a substantially dust-free product.

IPC: B60T1/00
Filed: 1995-07-05
Abstract: A parking lock mechanism for use in a vehicle drivetrain subassembly having an electric motor coupled to a reduction gear set with the gear set including a rotatable output member having a plurality of circumferentially spaced locking holes. The mechanism comprises a locking pin movably mounted in an end cover structure of the drivetrain subassembly and a cam rotatably mounted in the end cover structure and having an inner portion in contacting engagement with the locking pin. An actuator assembly is provided for applying a torsional load to the cam which urges the locking pin into contacting engagement with the output member when the locking holes are circumferentially misaligned with the locking pin and causes a predetermined rotation of the cam about its longitudinal axis from a released position to an actuated position when one of the locking holes is circumferentially aligned with the pin. The rotation of the cam to the actuated position forces the pin into a releasable locking engagement with the aligned one of the locking holes so as to prevent rotation of the output member of the vehicle drivetrain gear set.
