Title: Casing for projection television receiver and screen mounting method
Inventor: SHIMATANI TSUYOSHI
IPC: H04N5/74
Filed: 1992-06-29
Granted: 1997-12-16
Abstract: The present invention is directed to a method for installing a screen to a projection television receiver that uses a transmission-type screen such that the screen can be easily installed to and removed from the projection television receiver when multiple projection television receivers are combined to form a single large-scale multiple display system in which the receivers are stacked vertically and horizontally in an M x N rectangular configuration.  Screen holding brackets installed in the cabinet body and screen clamping frames are used to secure the screen in place by inserting the screen clamping frames into a slight gap formed between the cabinet body and the screen holding brackets.  Even when the screen clamping frames are inserted into the gap and adjusted to secure the screen, all movement of the clamping frames occurs within the dimensions of the cabinet body, thus making it easy to remove and install the screen even when multiple projection television receivers are combined in a single large-scale display system.

Title: Desensitizing anti-tartar dentifrice
Inventor: NORFLEET JAMES
IPC: A61Q11/00
Filed: 1992-09-17
Granted: 2003-01-28
Abstract: An oral composition, such as a toothpaste, includes an anti-tartar proportion of a polyphosphate anti-tartar agent (preferably with synthetic anionic polymeric polycarboxylate or equivalent, and fluoride) and a desensitizing proportion of a tooth pain inhibiting potassium salt which passes through exposed dentin tubules to tooth nerves or neurons, which salt can be potassium nitrate, potassium citrate or potassium oxalate, so that it helps to prevent tartar from forming on the teeth and also lessens any pain experienced by persons contacting their sensitive teeth with the oral composition. Preferably the oral composition is a desensi-tizing anti-tartar toothpaste or gel which, when the teeth are brushed with it, aids in removal of at least some tartar and prevents its reappearance, and at the same time diminishes any tooth pain that the brusher would otherwise experience due to such brushing. In preferred toothpastes the anti-tartar agent and the desensitizing agent are both potassium compounds and other components of the toothpaste, such as the detergent or surfactant, thickener, water soluble fluoride, anionic polymeric polycarboxylate, sweetener and any anti-calculus agent present, when they may be present as salts, will also be potassium salts. In place of the mentioned anti-tartar agents there may be employed other anti-calculus compounds, such as AHP (azacycloheptane-2-2-diphosphonic acid) or corresponding alkali metal salt, preferably the potassium salt, and in such case it is very desirable for other components of the toothpaste to be in the forms of their potassium salts.

Inventor: NASH THOMAS P
IPC: B65C9/18
Filed: 1993-05-17
Granted: 2004-02-03
Abstract: Linerless labels are produced by feeding a tape having a release coated face and an adhesive face to a hardened anvil vacuum cylinder, utilizing a non-stick circumferential surface feed roll. A knife blade on a cutting cylinder is rotated into contact with the tape at the anvil cylinder to cut the tape into linerless labels, and release liquid is applied to the blade after each cut. From the anvil cylinder the labels are deposited on a plurality of spaced conveyor tapes of circular cross section with the adhesive faces contacting the conveyor tapes. A vacuum chamber assists in holding the labels on the conveyor tapes. The release coat faces of the labels conveyed by the conveyor tapes may be heated and then printed with hot melt ink from an ink jet printer.      The labels are separated from the conveyor tapes using a peeler roll and non-stick stripper rings, and then immediately contact a moving web or other elements to which they are to be applied, with the label and web passing through nip rolls to activate the pressure sensitive adhesive.

Abstract: Paper sheets, such as creped tissue sheets used for converting into tissue products such as facial tissue and bath tissue, can be softened with by passing the sheets through one or more fixed-gap noncompactive straining nips formed between two engraved rolls having partially-engaged small straining elements of a shape which strains the sheet in all directions. The straining treatment substantially reduces the rigidity of the tissue sheet by increasing the internal bulk without substantially reducing the tensile strength. The method provides a means for making a throughdried-like tissue sheet from a wet-pressed tissue sheet.

Title: Bi-fold lid for container
Inventor: JAMISON BARRY
IPC: B65D43/04
Filed: 1994-03-28
Granted: 1999-08-10
Abstract: Abstract of the Disclosure A pair of bi-fold lids covers a container having a depth dimension that is less than half the width dimension of the container.  Each bi-fold lid has front and rear sections that are hinged together along a hinge axis.  The hinge axis is reinforced by adjacent flanges that overlap one another when the lids are in their closed position.  When the lids are open, the front and rear sections fold over on one another to reduce the extent to which they hang down adjacent the sidewall of the container.  This permits a container of short height or shallow depth to have lids.
