IPC: A61F13/534
Filed: 1994-11-18
Abstract: An absorbent structure having both osmotic and capillary absorbing capabilities. The absorbent structure comprises a capillary absorbent substrate, such as paper. The substrate has regions of relatively high and relatively low densities. The osmotic absorbent structure may include superabsorbents and is preferentially applied to the low density regions of the substrate.

Title: An inexpensive and easy-to-use mechanically operated bite force gauge
Inventor: HAMILTON PETER WORTHINGTON
IPC: A61B5/22
Filed: 1995-01-10
Abstract: In accordance with the present invention there is provided an easy-to-use mechanically operated bite force gauge for measuring the bite force at which a patient's dentures will begin to slip or dislodge within their mouth. The bite force gauge has two opposing beams each of which extends longitudinally between back and front ends. The beams are joined together by a back support column and by a bending support column. The bending support column defines, on each beam, a yielding member located between the two support columns and an extension member located between the bending support column and the front end. Thereafter, when biting forces are applied to the yielding members so that the two yielding members move towards each other, the extension members will move away from each other. The bite force gauge includes a force detector to measure the amount of force being applied to the yielding members by measuring the distance that the extension members move away from each other when the biting forces are applied.

Title: Axial-mounted high flow valve
Inventor: BURGESS ROBERT K
IPC: E03B9/02
Filed: 1997-04-16
Abstract: The invention includes an axial-mounted high flow rate valve by fixedly mounting a rotatable valve sealing element so that it pivots on an axis which is substantially parallel to a central axis of the pipe or conduit to which the valve is connected. The rotatable valve sealing element can be not only circular, but non-circular as well, having an extended length along the pivot axis for even greater flow rates and may be particularly suited for installations in sprinkler systems which require greater flow than a normal valve of the same diameter and may even be used as a combination valve for hydrant and sprinkler system use, such as in residential applications. The present invention also may include a purge port to purge residual fluid remaining in the valve, downstream of the valve sealing element, to assist in preventing freezing of the valve and it may include an air port to allow air to enter the valve to alleviate a possible vacuum created by the purging and to enable more effective purging.
