Patent CA-2163340-A1 (CA)
Title: A drug delivery composition for alpha-adreno receptor blocking agents
Inventor: ILLUM LISBETH
IPC: A61K31/505
Filed: 1994-05-27
Abstract: The invention provides an oral drug delivery composition comprising an .alpha.-adreno receptor blocking drug characterised in that the composition is adapted to release a first portion of the drug in the upper gastrointestinal tract and to release a second portion of the drug by sustained release in the terminal ileum and/or the colon. This composition  provides a two phase release profile which maintains sufficient and steady plasma levels for therapeutic effect whilst minimising side effects by avoiding a high peak in plasma levels.  The sustained release of the second and optionally the first portion of the drug is achieved by a controlled release system such as a hydrophilic gel matrix. The specific release of the second portion of the drug in the colon can be achieved by coating tablets containing the second portion with a pH or redox sensitive coating such as a polymethylmethacrylate.
Patent CA-2163833-A1 (CA)
Title: Press blanket and method for producing the same
Inventor: AUFRECHT HARALD
IPC: D21F3/02
Filed: 1995-11-27
Abstract: A press blanket for a pressing device intended for extracting water from a web in the press nip of a papermaking machine comprises an elastomeric matrix, in which the outer area, facing the web, is subjected to a thermal treatment in order to increase the wear-resistance. Although the elastomeric matrix thus consists of the same material throughout, the outer area, which is subjected to greater stresses, therefore exhibits increased wear-resistance. The press blanket is made in a single operation, by casting a hot-casting elastomeric matrix onto a cylindrical casting mold, while at the same time reinforcing threads are wound into the material. The press blanket is selectively thermally treated in order to achieve increased wear-resistance at the outer surface facing the web.

Title: Film for cook-in applications with plural layers of nylon blends
Inventor: RAMESH RAM K
IPC: C08L77/00
Filed: 1995-11-29
Abstract: The present invention is a multilayer film having a first layer including a blend of a crystalline nylon and a material which disrupts the crystallinity of the crystalline nylon; a second layer also including this blend; and a third intervening layer, between the first and second layers, including a material having a modulus lower than the modulus of the crystalline nylon, and having a crystallinity of less than 60%. The nylon blend layers, which can be two or more in the film, add toughness and stiffness, but also elastic recovery to the final film. The intervening layer or layers of a material with relatively low modulus and crystallinity aid in orientation of the film during manufacture, permitting the use of more of the crystalline nylon than would be practical if only a single nylon layer was used.

Title: Ozone enriched process gas
Inventor: LANG HELMUT
IPC: C01B13/10
Filed: 1996-04-25
Abstract: In a method of producing an ozoniferous process gas in which oxygen or an oxygen-containing charge gas is enriched with ozone in an ozone producer, the process gas leaving the ozone producer and enriched with ozone is fed to a compressor or a compressor group consisting of a plurality of compressors connected in parallel and is brought in the latter to an essentially constant pressure increased relative to the pressure on the suction side of the compressor, and is then fed to a reaction vessel. The process gas delivery flow in this case  is  adjustable and/or controllable.          In  order  to  now  increase  the  delivery-flow control  range without  there  being  the  risk  of  ozone destruction,  a  gas-flow  control  member  is  arranged upstream of the compressor or the compressor group on the suction  side.  The  variable  mass  flow  is  adjusted essentially via a variable suction-gas density upstream of the compressor or the compressor group.

Filed: 1996-12-20
Abstract: A plug is used in welding a female-threaded boss into a hole through a part, the plug being installed in the boss prior to welding (preferably at the plant of the supplier of the bosses, so that they already have the plug installed when they arrive for welding).  The plug has a head and a cylindrical portion extending below the head, the cylindrical portion having male threads adapted to be received by the female threads of the boss.  The head has a minimum transverse dimension of at least the maximum transverse dimension of an upper surface of the boss so as to completely cover the upper surface.  The cylindrical threaded portion of the plug has thread-cutting edges defined therein, configured to re-tap the threads of the boss when an installed plug is rotated in the direction necessary to remove the plug from the boss.  The head of the plug has a recess therein, having two portions, namely an upper circular recess, and a lower hexagonal recess, the circular recess being configured to receive a tool to permit the plug to be held in place while the weld is effected, and the hexagonal recess permitting a tool to be inserted once the plug is no longer needed, so that it can be unthreaded from the boss.  Optionally, a copper cup washer may be used, the cup washer being configured to fit between the head and the boss, with the cup portion extending upwardly away from the boss, to isolate the head and the plug from the boss, thereby reducing any likelihood of the plug and the boss being accidentally welded together.
