Patent CA-2422161-A1 (CA)
Inventor: ROMANUFA KERILEY K
IPC: G06F17/30
Filed: 2003-03-14
Abstract: The use of a centralized version table allows for efficient object switching. Rather than synchronizing all database agents to recognize a newly created file as containing the most recent version of a given object, database agents requiring access to the given object need only consult the centralized version table to learn file identity information. That is, the database agents consult the centralized version table to determine which of the files associated with a given object contain the most recent version of the given object. Mechanisms associated with the use of the centralized version table also provide for efficient recovery from a failure that has occurred during an object switching transaction.

Title: Multi-layer security mat for playground surface
Inventor: PHAN PATRICK
IPC: E01C13/06
Filed: 2003-06-13
Abstract: The present invention relates to a multi-layer security mat for covering a playground surface, comprising a top abrasion layer, an intermediate charge-distributing layer and a bottom shock-absorbing layer. The intermediate charge-distributing layer is interposed between the top abrasion layer and the bottom shock-absorbing layer for distributing charges applied to the top surface of the top abrasion layer on the bottom shock-absorbing layer. The bottom layer absorbs shocks applied to the top surface of the top abrasion layer. The top abrasion layer, the intermediate charge-distributing layer, and the bottom shock-absorbing layer increase in thickness while they reduce in density. To manufacture the multi-layer security mat, a prefabricated panel of expanded polypropylene is disposed generally horizontally to form the bottom shock-absorbing layer. A first mixture of (a) granules of rubber material and (b) polyurethane is poured on the top surface of the prefabricated panel of expanded polypropylene and, then, is cured to form the intermediate charge-distributing layer. A second mixture of (a) granules of rubber material and (b) polyurethane is finally poured on the top surface of the intermediate charge-distributing layer and then cured to form the top abrasion layer.

Title: Vacuum sweeping system for automatic scrubber
Inventor: FIELDS WILLIAM A
IPC: A47L11/30
Filed: 2003-10-02
Abstract: A vacuum sweeper is cantilevered to a hinged bracket mounted to the front of a conventional automatic floor scrubber. The sweeper includes a vacuum head, an overlying debris ramp, and two vertically rotating, conical brushes having their base ends in contact with the floor. The base end of the conical brushes sweep a path at the edge of the vacuum sweeper in excess of the width of the scrubber. The entire vacuum sweeper apparatus is mounted for vertical excursion relative to the cantilevered mount to the hinge bracket to enable up and down excursion of the sweeper and vacuum responsive to either scrubber motion or inevitable floor irregularities encountered during floor scrubbing. Where vacuuming is not required in advance of scrubbing, such as during double scrubbing or floor stripping cycles, provision is made to hinge the vacuum sweeper upwardly away from floor engagement. A ramp is used in conjunction with the vacuum for collecting large debris.

IPC: A41D1/00
Filed: 2002-05-03
Abstract: A bi-stable hook component (20) of a touch fastener can bend into, and remai n in, a stable concave position. Another stable position enables initial engagement with a mating component (e.g., a loop component 22). The concave position applies engagement-enhancing tension to the engaged loops (28), and in some cases forces end portions (38) of the hooks (24) into close proximit y with one another to secure the fastening and to produce a curved touch fastener that, as engaged, can better conform to an underlying curved surfac e, such as the contour of a wearer's body. Absorbent articles are provided with such a bi-stable fastening system (48).
