Patent CA-2195358-C (CA)
Inventor: SCHNEIDER MARK C
IPC: B05C17/01
Filed: 1997-01-17
Granted: 2000-06-27
Abstract: A high thrust drive system usable in a variety of devices, e.g.,  fluid dispensing,  article clamping,  article lifting and article jacking, includes a driving rod member, an actuating member movable through a driving stroke and a return stroke, and a gripping plate having a passage therein through which the driving rod extends for gripping the driving rod and moving the rod in a thrust-applying direction during the driving stroke of the actuating member.  The actuating member imposes a high thrust on the driving member through the gripping plate during the driving stroke, and the gripping plate imposes a torque on the driving rod in a first rotational direction as the actuating member is moved through the driving stroke.  A recoil plate is oriented to grip the driving rod during the return stroke of the actuating member and impose a torque on the driving rod in the same first rotational direction as the gripping plate to precule movement of the driving rod in a direction opposite the thrust-applying direction, whereby applying a torque on the driving rod in the same rotational direction during the driving and return strokes of the actuating membrer imparts a smooth, linear motion to the driving rod as the driving rod is moved in the thrust-applying direction.

Title: Scrap melting process
Inventor: SHIKADA TSUTOMU
IPC: C21B5/00
Filed: 1996-04-30
Granted: 2004-03-23
Abstract: Disclosed herein is a scrap melting process for the production of molten iron from scrap (as the source of iron) and of high-calorie exhaust gas (as a valuable fuel gas) from pulverized coal (as the principal source of heat and a partial source of high-calorie exhaust gas) and waste plastics (as the principal source of high-calorie exhaust gas and a partial source of heat). The process comprises charging a shaft furnace (equipped with a burner at the tuyere) with scrap (as the iron source) and coke and optional waste plastics from the furnace top and injecting pulverized coal (or pulverized coal plus waste plastics) and oxygen through the burner under specific conditions, so as to mix together pulverized coal (or pulverized coal plus waste plastics) and oxygen, thereby achieving rapid combustion of pulverized coal etc., thereby causing the sensible heat of the combustion gas to melt the scrap and produce molten iron therefrom and recovering the combustion gas as a fuel gas without intentional secondary combustion in the furnace.

Abstract: An internal combustion engine includes a mechanism for releasing compression from the cylinder during starting. That mechanism has an actuator attached to the engine camshaft for sliding between first and second positions. In first position the actuator is engaged by a lifter to open the engine exhaust valve during the compression phase of the combustion cycle. At the second position, the valve lifter does not engage the actuator and the exhaust valve remains closed during the compression phase. A weight lever is pivotally attached to the camshaft and drives the actuator between the first and second positions in response to engine speed. At slow speeds occurring while before the engine starts, the actuator is held the first position so that the compression is relieved. After the engine starts, centrifugal force causes the weight lever to drive the actuator into the second position at which normal compression occurs.

Abstract: A fibrous sheet coated with a water-soluble binder of polyvinyl alcohol is impregnated with an aqueous solution dissolved with water-soluble carboxylate, so as to produce a water-disintegratable fibrous sheet. Salting. out of the polyvinyl alcohol with the carboxylate maintains wet strength of the water-disintegratable fibrous sheet even in a wet state, which is easily disintegrated when immersed in a large amount of water after use. Furthermore, it does not suffer from deterioration in water-disintegratability and wet strength if it is left at high temperatures, and is good in water-disintegratability in cold water.

Abstract: To separate ink particles from pulp, composed of a wide variety of used paper materials for recycling, the pulp flow (E2,S2;E3,S3) is subjected to at least one current of air bubbles (C). A counter current of water (E1) is in the flow of air bubbles (C) to detach the ink particles, after they have passed through the pulp and carry the ink particles with them. The counter water current detaches the carried particle matter and any fibers, and carries them off in the water flow.
