Patent CA-2294369-A1 (CA)
Inventor: OSBORN THOMAS WARD III
IPC: A61L15/26
Filed: 1998-06-09
Abstract: Absorbent devices, and more particularly toilet-disposable absorbent devices that are worn interlabially by female wearers for catamenial purposes, incontinence protection, or both, are disclosed. The absorbent interlabial device of the present invention comprises a central absorbent portion and preferably a pair of flexible extensions joined to the central absorbent portion. The main absorbent portion comprises an upper portion, and a lower portion opposed to the upper portion. In use, the upper portion is positioned furthest inward into the space between the wearer's labia majora. The pair of flexible extensions extends downwardly and laterally outward from the upper portion of the main absorbent portion, and preferably is capable of maintaining contact with the inside surfaces of the wearer's labia majora when the wearer's body goes through a range of motions, including squatting. Additionally, the flexible extensions are preferably capable of covering the fingertips of the wearer as the absorbent device is inserted into the interlabial space. The components of the absorbent device are preferably biodegradable. The device disperses into a plurality of fragments when exposed to mildly agitated room temperature water. The small size of the device contributes to its flushability. The dispersibility, flushability, and biodegradability of the device all contribute to the ability of the device to be effectively and reliably disposed of in a toilet.

Patent CA-2306166-A1 (CA)
Inventor: ROBINSON DANE Q
IPC: A61C17/22
Filed: 1998-10-08
Abstract: This invention is an apparatus (10) for cleaning the surface of teeth in a human mouth having a flexible, resilient central flossing filament (34), and a plurality of flexible side flossing filaments (42) fixedly attached to a central filament intermediate portion (40). The central filament intermediate (40), and free end portions with the side flossing filaments (42) attached thereto are sized to be received between adjacent teeth without traversing any contact areas between the adjacent teeth from at least the front of the mouth.  The central filament (34) has sufficient flexibility, and the resiliency to effect a first flossing action between the adjacent teeth by imparting a first flossing motion to the central filament. The side filaments have sufficient flexibility to effect a second flossing action between the adjacent teeth at the forward, and rearward surfaces thereof to impart a second flossing motion to the side filaments. An electric motor (24) is coupled to the central filament base portion to provide a rotational or an oscillatory drive to the central filament base portion to impart the first, and second flossing motions. The central filament (34) has greater resiliency than the side filaments (42). The side filaments (42) have greater flexibility than the central filament (34), and are sufficiently flexible to bend back adjacent the central filament upon insertion between the adjacent teeth. Upon a drive force being applied thereto through the central filament the side filaments whip or flail about, and in one embodiment are rotated to spin about the longitudinal driven axis of the central filament.

Abstract: A method for selecting a drilling parameter is disclosed. The method includes determining a loading displacement relationship for samples of earth formations. The loading displacement measurements are made by an indenter. The drilling parameter is selected from the loading displacement relationship. In one embodiment of the invention, the loading displacement relationship is determined from cuttings made during drilling of a wellbore. The loading displacement relationship determined during drilling is used to select at least one drilling parameter during drilling to improve drilling performance. Drilling parameters which can be selected include mill tooth and/or insert bit type; type of gauge protection to be used on the bit; type, size and orientation of jet nozzles on the bit; and blade structure, cutter type and density as well as the cutter impact resistance for fixed cutter bits. Other drilling parameters include weight on bit, drill bit rotation rate, and drilling fluid flow rate.
