Filed: 1997-08-29
Abstract: A toilet flushing device has a body with an inlet and an outlet. There is a valve seat in the body in the flow path between the inlet and the outlet and a valve in the body movable toward and away from the valve seat to control water flow through the toilet flushing device. A handle assembly for causing movement of the valve toward and away from the valve seat includes a socket attached to the body and a handle mounted in the socket for pivotal movement. A plunger is positioned in part within the socket and is in contact with the handle. Pivotal movement of the handle causes axial movement of the plunger with a portion of the plunger being positioned for contact with valve for causing movement thereof. There is a spring for biasing the plunger toward the handle. A bushing is attached to the socket and has a central bore within which the plunger moves. A seal member is attached to the bushing and forms a seal therewith.      The seal member has a central passage with the plunger being positioned within this central passage. The seal member has a plurality of spaced inwardly extending circumferential seal lobes which are in sealing contact with the plunger at axially spaced locations thereon. The lobes define at least one recess therebetween and there is lubricant within the at least one recess.

Title: Improvement in the synthesis of tributyltin lithium
Inventor: BETHEA TRISTRAM W
IPC: C08F236/12
Filed: 1997-12-10
Abstract: Triorgano substituted-tin lithium initiators are made in a dimethyl ether solvent.  The substitution of dimethyl ether as the solvent for the traditional tetrahydrofuran solvent results in an initiator for anionic polymerizations that can produce less 1,2-vinyl repeat units.   The dimethyl ether is also easier to remove from the polymerization media because it has a boiling point at one atmosphere of minus 24.8°C and thus is a gas at 25°C.

Patent CA-2230721-A1 (CA)
Title: Side airbag substitute of seat for any vehicle
Inventor: GO GIOK DJIEN
IPC: B60N2/42
Filed: 1996-07-25
Abstract: As yet great intrusion of vehicle side into a passenger compartment of motor-vehicle in side collisions causes injury- and whiplash-related deaths linked to collapse of the totally deformed vehicle side and incapability of side airbags to absorb great lateral energy and prevent the intrusion thereof. In any side collision a side airbag-substitute removes a passenger, sitting on the seat rotating about an inboard and/or outboard floor rail, from an injury-prone area to a vehicle-centre during which lateral energy is lowered by work of fracture of sites of predetermined fracture of the outboard floor rail and the removal of the passenger and seat and the remaining energy is absorbed by at least one energy absorber, which in conjunction with a side impact member, longitudinally arranged between the vehicle side and seat, withstands the intrusion thereof, and transmitted into the vehicle floor.   In the second feature of invention, whiplash-related oscillations are dampened and lateral energy is substantially absorbed by the energy absorber.   In the third feature, the energy absorber is designed with a progressive spring rate to achieve a larger working area and minimize the depth of intrusion.   In the fourth feature, in order to save costs and avoid false deployments a front airbag is converted into a safety airbag which is inflated in the event of front and/or side collision. Owing to the features to withstand the intrusion thereof and to remove the passenger to the vehicle-centre in side collisions the deployment time can be prolonged.   In the fifth feature, in order to save costs all the transversely-assembled energy absorbers of the front and successive seats are connected to a single longitudinally-assembled energy absorber.
