Patent CA-2008044-C (CA)
Title: Webbing lock device for webbing retractor
Inventor: MORI SHINJI
IPC: B60R22/38
Filed: 1990-01-18
Granted: 1998-06-23
Abstract: A webbing lock device for a webbing retractor in which a takeup shaft is locked and prevented from rotating in a webbing drawing-out direction when the takeup shaft has rotated by a predetermined amount in the webbing drawing-out direction after meshing engagement between a lock wheel and a pawl lever.  The webbing lock device is provided with a ratchet wheel which is disposed coaxially with the takeup shaft and has around an outer peripheral portion thereof external ratchet teeth capable of meshing with the pawl lever.  The ratchet wheel is adapted to receive a rotating force of the takeup shaft in the webbing drawing-out direction via a frictional force when the takeup shaft rotates in the webbing drawing-out direction, while the ratchet wheel is rotated integrally with the takeup shaft by engaging with the takeup shaft when the takeup shaft rotates in a webbing taking-up direction.  The pawl lever is spaced apart from the lock wheel by the external ratchet tooth when an amount of rotation of the takeup shaft in the webbing taking-up direction with the lock wheel meshing with the pawl lever is less than the predetermined amount.          As a result, since the pawl lever is forcedly spaced apart from the lock wheel by the ratchet wheel when the takeup shaft rotates in the webbing taking-up direction, an increase in the tension of the webbing is prevented when the vehicle is run on a rough road.

Title: Relief valve for liquid filter
Inventor: VANDENBERK THEODORUS ARNOLDUS
IPC: B01D27/00
Filed: 1990-07-09
Granted: 2001-01-30
Abstract: A liquid filter as disclosed which includes a housing in which a filtering media is disposed. A relief valve permits the liquid filtrate to bypass the media when the pressure differential across the media exceeds a predetermined level. The relief valve includes a valve member consisting of a valve disc from which four legs extend. The valve closure spring engages the legs to maintain the valve closed until the pressure differential attains a predetermined level. The legs are designed so that only two of the legs engage the spring during normal operation of the valve. Accordingly, the other two legs remain unstressed by the valve spring, but can engage the edge of the valve aperture in case of failure of one or both of the other legs to prevent the valve member from falling into the liquid filtrate, thus blocking the flow of liquid filtrate to the engine, causing catastrophic failure of the engine.

Title: Bi-directional snap-action register display mechanism
Inventor: MARSHALL JOHN D
IPC: G06M1/24
Filed: 1990-11-08
Granted: 2000-01-25
Abstract: A bi-directional snap-action register mechanism for an odometer-type mechanical register display. The mechanism includes at least one register display wheel and a bi-directional cam mounted coaxially along a common shaft with the register display wheel. The bi-directional cam engages a helical groove formed along the shaft to allow lateral displacement of the bi-directional cam in a direction parallel to a rotational axis of the shaft. A pin is biased by a spring into contact with the bi-directional cam. Rotation of the shaft causes the bi-directional cam to be moved with respect to the pin. The cam abruptly rotates through a predetermined angular distance when the point of contact of the biased pin with the cam moved from a smooth portion to a step transition portion of the cam. The abrupt rotation of the cam is communicated to the register display wheel to cause a new display position to be moved into view.

Title: Asynchronous resynchronization of a commit procedure
Inventor: BRITTON KATHRYN H
IPC: G06F9/46
Filed: 1991-04-12
Granted: 1995-10-10
Abstract: A computer system and process efficiently provides resource  recovery  for  a  failure  during  a  commit procedure.   An application is run on a processor and requests a work operation involving a resource such as a protected  conversation with  another  application  in  a different real machine.  A commit procedure is begun for the  work  request,  and  if  the  commit procedure  fails before  completion,  the  following  steps  are  taken  to optimize the use of one or both of the applications.  At some time after the commit procedure fails, a return code is sent to at least the application that initiated the commit indicating the result of the application commit order and that the application can continue to run and does not have to wait for resynchronization (recovery). Then, while the initiating application continues to run and   do   other   useful   work,   resynchronization   is implemented in parallel, asynchronously.

Title: Flow system disconnect and method
Inventor: NIMBERGER SPENCER
IPC: F16L55/10
Filed: 1992-12-15
Granted: 1999-04-27
Abstract: An improved system and method are provided for normally interconnecting a stationary flow line and a flexible flow line, and for automatically separating the flow lines in response to movement of the flexible flow line in excess of a preselected limit. A connection comprises a socket housing sealed to one flow line and a ball housing sealed to another flow line. The housings are separated automatically when a lateral force is transmitted through the flexible flow line to cause excess pivoting movement of one housing related to the other housing. The connection of the present invention is particularly useful for preventing rupture of a flow line during an intermittent pullaway of a portable vessel with respect to a stationary holding tank. In one embodiment, the connection includes at least three ball swivel surfaces for mating engagement with a socket swivel surface. Valve members in each of the housings are held out of engagement with respective seating surfaces when the housings are mated, and automatically close to prevent fluid loss when the housings separate. A seal is provided for maintaining sealed engagement between the ball housing and socket housing when the ball housing normally pivots within a preselected arc limit with respect to the socket housing. The elastomeric seal preferably engages a seating surface forming a portion of an imaginary sphere having a center coincident with a sphere which defines the ball swivel surface and socket swivel surface.
