Title: Hot-gas-filtering fabric of spaced uncrimped support strands and crimped lofty fill yarns
Inventor: FISCHER EDWARD M
IPC: B01D39/08
Filed: 1992-12-14
Abstract: A fabric for filtering particulate matter from a stream of hot gases, e.g., from a diesel engine, has an unknotted weave of flexible, incompressible, uncrimped, spaced support yarns and flexible, lofty, fully crimped, fill yarns. During the weaving process, the fill yarns are pulled tightly against the support yarns so that they do not slip or shift. For greater assurance of good filtering, a filter employs multiple layers of the fabric, with the support yarns of each layer extending orthogonally to those of adjacent layers. For uses involving prolonged exposure to high temperature, both the support yarns and fill yarns can be continuous-filament ceramic yarns such as alumina-boria-silica yarns. For lower temperatures, the yarns can be primarily glass.
Patent CA-2128445-A1 (CA)
Title: Two-way clutch
Inventor: ROBINSON ALLEN C
IPC: F16D41/067
Filed: 1994-07-20
Abstract: A two-way free-wheeling clutch is formed between a drive shaft and a driven shaft concentric with and encircling at least a portion of the drive shaft that is formed by axially extending substantially chord forming portions. The chord forming portions cooperate with circular bearings interposed between the portions and a circumferential surface of the encircling portion of the driven shaft to drive the driven shaft from the drive shaft. Drive of the driven shaft by the drive shaft is obtained by relatively positioning the bearings and the portions so the bearings are toward the radial extremities of their respective chord portions a driving wedge is formed with the inner circumferential surface of the driven shaft. When the portions and the bearings are shifted to relatively position the bearings closer to the centre of the chord forming portions i.e. minimum radial position on the chord free rotation of the driven shaft freewheeling of the driven shaft is permitted.  Circumferential movement of the circular bearings is impeded so that the relative positions of the circular bearings and their respective portions automatically change with a change in direction of rotation of the drive shaft or by simply stopping rotation of the drive shaft.

IPC: B65H29/18
Filed: 1994-08-05
Abstract: ABSTRACT                 COUPON SORTER             A system for sorting coupons according to information contained within bar codes or similar markings printed thereon.  The system includes a storage bin in which the coupons are received and from which they are removed one at a time.  A coupon picker removes the coupon from the storage bin and deposits it upon a conveyor belt at a loading station.  The information contained on the coupon is read by an appropriate scanner which ascertains through the use of an appropriate data processing system the address of a receiving bin in which the coupon is to be deposited. The position of the coupon on the conveyor belt is tracked and when the coupon arrives at the address of the receiving bin an air jet is activated to propel the coupon from the conveyor belt into the receiving bin.

Abstract: A fast response weld head (2) and a control system (60) allows user control of critical welding parameters such as speed, force, position, and duration. In one embodiment, the control system (60) includes a position servo loop (64, 66, 16, 50, 70) attached to a motor driven output shaft (36) on which a welding electrode (38) is mounted utilizing a follow-up spring assembly (44). During a weld cycle, the control system (60) moves the welding electrode (38) toward a workpiece (46) at a rapid user-defined rate. Just prior to contact this rate is reduced to prevent damage to the parts. When contact is made, the force exerted by the electrode (38) on the workpiece (46) is measured until the measured force equals a user-defined optimum welding force.  When the weld is complete, the welding electrode (38) is automatically raised by the control system (60) releasing all pressure on the workpiece (46).

Title: Method of producing coke for the iron and steel industry
Inventor: MECKEL JOACHIM F
IPC: C10B57/06
Filed: 1994-02-25
Abstract: Proposed is a method of producing coke for use in the manufacture of iron and steel, in particular foundry coke, by mixing charge coal and about 0.5 to 10 %, relative to the coal in the water-free and ash-free state, of a binder, and then coking the mixture. The aim is to produce coke with a relatively low reactivity, the highest possible unit density, the highest possible carbon content and the largest possible lump size. Used as the binder is a vacuum-hydrogenation residue produced in the vacuum distillation stage of the hydrogenation of short residues or heavy oils derived from crude oil, with the addition of an additive consisting of porous carbon bodies made, in particular, of material derived from coal.

Title: Method and apparatus for controlling the stroke of a hydraulic hammering device
Inventor: COMARMOND JEAN SYLVAIN
IPC: B25C1/04
Filed: 1995-11-23
Abstract: The regulator consists of a piston (1) which moves inside a cylinder between upper (8) and lower (9) chambers which are fed in sequence with a high-pressure fluid by a distributor (4) linked to a control member allowing the piston stroke to be varied. The regulator incorporates a slide valve (13) with a return spring (9), located inside a cylinder with one of its faces capable of being subjected to a fluid pressure. The regulator is able, during the piston rebound phase following an impact, to establish the presence of an instantaneous flow of fluid from the upper chamber (8) to the feed circuit (5) at a pressure determined from the pressure differential between the two circuits. In the event of a flow being detected, fluid is fed under pressure to the slide valve so that the stroke of the piston is increased.
