Title: Absorbent interlabial article
Inventor: OSBORN THOMAS WARD III
IPC: A61F13/82
Filed: 1998-11-25
Granted: 2005-07-26
Abstract: Absorbent devices, and more particularly absorbent devices that are worn interlabially by female wearers for catamenial puposes, incontinence protection, or both, are disclosed. The absorbent interlabial device of the present invention comprises a main absorbent portion with an upper portion, a lower portion opposed to the upper portion, and two ends. The upper portion faces toward the vestibule of the wearer during insertion of the device into the wearer's interlabial space and during use. The ends of the absorbent device are preferably taped so that the lower portion of the interlabial device is longer than the upper portion. The ends are also provided with at least one curvilinear segment, with the ends preferably having a sinusoidal or S-shape. The absorbent interlabial device preferably also has an arcuate pattern of discrete autogenous bonds. The combination of the preferred S-shaped ends and the arcuate bonding pattern provides greater product stiffness control for simultaneous improved comfort and handling characteristics.

Title: Beneficial agent delivery system with membrane plug
Inventor: HOM LAWTON
IPC: A61K9/00
Filed: 1998-07-24
Granted: 2007-09-25
Abstract: An osmotic delivery system for controlled delivery of a beneficial agent includes an implant capsule containing a beneficial agent and an osmotic agent which swells on contact with water causing the release of the beneficial agent over time. The osmotic delivery system has a membrane plug which allows water to pass through the plug from an exterior of the capsule while preventing the compositions within the capsule from passing out of the capsule. A delivery rate for delivery of the beneficial agent from the implant capsule is controlled by varying a core diameter of the membrane plug within a constant diameter capsule. The membrane plug has a variable water permeation rate depending on an extent to which the membrane plug is constrained by the capsule walls.

Granted: 2008-04-08
Abstract: Disclosed is a liquid phase adsorption process for removing and concentrating heteroatom compounds in hydrocarbons (HCH), comprising the steps of adsorption, copurging and regeneration. In the adsorption step, a liquid hydrocarbon stream is fed to an adsorber, which adsorbs HCH and returns adsorption effluent. In the copurging step, HCH, which are extracted from the previous regeneration, are applied to the adsorber, displacing copurging effluent. In the regeneration step, a polar solvent is flowed through the adsorber, purging HCH. Most of the HCH are then set aside for being used in the next copurging step while a small amount of the HCH are taken out from the process as HCH product. The present invention is economically advantageous in effectively removing HCH from the hydrocarbon stream and increasing HCH concentrations within HCH product.

Abstract: For use with an elongate conveyor belt designed to transport articles from one location to another, a novel pusher device mounted adjacent one long side of the belt. The pusher device utilizes an elongate, rotatably mounted arm having first and second ends, with the first end being pivotally affixed at a location relatively close to the belt, and arranged to rotate about the fixed pivot for less than 90°. The arm normally resides in an inactive position extending along the long side of the belt, with the second end of the arm being arranged to move outwardly, on occasion, from the inactive position and across at least a portion of the belt when an article is to be deflected off of the belt. An article-engaging paddle is pivotally mounted on the second end of the arm, and a novel actuating device causes selected rotation of the arm about the fixed pivot, such that upon the actuating means being activated to cause the arm to undertake rotation about the fixed pivot, the paddle will move in an outward stroke to briefly contact the selected article and to cause such article to be deflected off of the belt. The actuating device thereafter causes the arm to undertake a rapid return stroke and to resume its inactive position.
