The synchronizer further comprises a plurality of circumferentially spaced struts that are disposed between the guide hub and the shift sleeve so that the struts slide axially with respect to the guide hub and the shift sleeve, and detents operatively connecting the struts to the shift sleeve when the shift sleeve is in the central neutral position so that struts follow the shift sleeve when it slides axially with respect to the guide hub until forces applied to the struts exceed a predetermined limit.  The synchronizer further includes an output member and a blocker ring that is disposed between the guide hub and clutch teeth of the output member.  The blocker ring has axial drive slots for indexing the blocker ring circumferentially with respect to the output member.  The struts have depending tabs at one end that are disposed in the drive slots.  The depending tabs have a dual function acting as drive lugs for indexing the blocker ring circumferentially with respect to the output member and also as stops that engage the input member to limit axial translation of the struts with respect to the guide hub when the shift sleeve is retracted from the extended engaged position.

Title: Disk drive array memory system using nonuniform disk drives
Inventor: WALSH ROBERT
IPC: G06F3/06
Filed: 1992-02-04
Abstract: The data storage subsystem (100) is implemented using an array of data storage elements (122-* to 125-*) which vary in data storage characteristics and/or data storage capacity. Control apparatus (101) automatically compensates for any nonuniformity among the data storage elements (122-* to 125-*) by selecting a set of physical characteristics that define a common data storage element format. The selected set of physical characteristics may not match any of the disk drives (122-1 to 122-n+m) but each disk drive (122-1 to 122-n+m) can emulate these selected characteristics. This capability enables the disk drives (122-* to 125-*) in the data storage subsystem (100) to be replaced by nonidentical disk drives in a nondisruptive manner to provide continuous data availability.

Title: Method for Hydrophilizing Absorbent Foam Materials
Inventor: DESMARAIS THOMAS A
IPC: C08J9/40
Filed: 1992-08-07
Abstract: Normally hydrophobic foams, such as polyurethane foams and polymerized water-in-oil emulsion foams, are rendered hydrophilic by means of treatment with sorbitan monolaurate.  Thus, a polymeric foam can be prepared or treated with sorbitan monolaurate and thereafter dried to leave a substantially uniformly distributed residue of sorbitan monolaurate on the internal foam surfaces. The resulting treated foams are rendered hydrophilic and are thus suitable for use in absorbent devices, including diapers, sanitary napkins, bandages, and the like.

Patent CA-2117259-A1 (CA)
Title: Adjustable coupling
Inventor: VIEHBACHER KURT
IPC: B62K27/12
Filed: 1994-04-07
Abstract: This device joins a bicycle to a hitch mechanism, which in turn joins to a trailing carrier (trailer). The invention is a consequence of the unique design parameters of the trailer mentioned and the fact that no other product addresses the situation. The mechanism consists of two (2) steel v-blocks welded to studs which are threaded into an extending arm body such that the plot of the v-block integrates with various bicycle frames, specifically the left chainstay and left rearstay. This unit is clamped to the bicycle by means of two (2) bolts passing through the arm body, frame and into the lugs welded to a backing bar. Tightening of the bolts draws the backing bar towards the arm body, clamping the frame into the v-block. Both the v-block and backing bar have hard rubber pads bonded to the critical surfaces to protect the bicycle from abrasion and to prevent the transmission of shock from extreme motion. When installed the entire unit will be on the same vertical and horizontal plane as the bicycle.

Title: Ratcheting screwdriver
Inventor: THOMPSON CHRISTOPHER D
IPC: B25B13/46
Filed: 1994-10-13
Abstract: A ratcheting driver handle has a ratchet body press-fitted axially in one end thereof, the body defining a socket which receives a gear for rotation coaxially with the handle.  The socket also receives two pawls respectively disposed above and at opposite sides of the axis and spring-biased into engagement with the gear.  A selector cap rotates on the housing and carries a first pin for driving the pawls respectively out of engagement with the gear, depending upon the direction of rotation, to control the ratchet direction.  A second pin on the cap engages an over-center leaf spring mounted in the socket below the gear for resiliently retaining the mechanism in either of the forward or reverse conditions.  A driver bit has a flattened end which is received through an axial bore in the cap and into a complementarily shaped bore through the gear for rotation therewith, being frictionally retained in place by a retaining ring.
