Title: Process for making antimicrobial agents in aqueous dispersion form containing 2-(4-thiazolyl)-benzimidazole alone or in combination with 1,2-dibromo-2,4-dicyanobutane
Inventor: BIALOSKY DAVID H
IPC: A01N25/30
Filed: 1996-07-23
Abstract: Aqueous dispersions of 2-(4-thiazolyl)-benzimidazole (TBZ), alone or in combination with 1,2-dibromo-2,4-dicyanobutane (DBDCB), and processes for making the same, are disclosed. These processes generally comprise mixing a xanthan gum with water, adding TBZ and mixing until uniform. DBDCB dispersions are prepared by mixing xanthan gum with water, adding DBDCB, maintaining the mixture at a temperature below about 40°C, grinding the mixture and mixing until uniform. The TBZ and DBDCB dispersions are then blended to prepare a dispersion containing both active ingredients. A method for inhibiting microbial growth utilizing these dispersions is also claimed.
Patent CA-2183756-A1 (CA)
Inventor: RENTSCH RUDOLF A
IPC: B65D43/16
Filed: 1995-02-23
Abstract: A hinge, preferably made of plastics material, has two connecting arms (5.1, 5.2) arranged at a distance (k1, k2) apart which connect a closure part (1) and a closure body (2). Each connecting arm has at least one relatively rigid intermediate part (4) and a coupling element (7) which executes a relieving movement. The coupling element (7) protrudes movably from the corresponding hinge part (1, 2). Two bending regions (9.1, 10.1; 9.2, 10.2) which form an angle with each other delimit the intermediate part (4). The connecting arms (5.1, 5.2) may be parallel or non-parallel to each other or be bent in one plane. When folded out, the connecting arms snap into the shape of the arch of a bridge, without large material elongations, a compensating movement deviating the excess stress laterally in the dead centre. As a result of an additional bending region (11.1, 11.2, 12.1, 12.2), with or without a snapeffect, in each connecting arm, the opening angle is substantially increased andtri-stable or multi-stable opening or closing, as desired, is achieved.

Patent CA-2197015-A1 (CA)
Inventor: VAN DEN SYPE JAAK STEFAAN
IPC: C21D3/04
Filed: 1997-02-07
Abstract: A closed-loop control system controls introduction of either water or hydrogen into a furnace region where a part is subjected to an elevated temperature to accomplish a heat treatment process.  The heat treatment process causes the part to participate in reduction and/or oxidation reactions which remain in balance at the elevated temperature so long as a hydrogen/water ratio set point is maintained.  The system includes an oxygen probe in communication with the furnace region for providing (i) an oxygen output indicative of sensed oxygen concentration within furnace region, and (ii) a temperature output indicative of temperature therein. A controller determines from the oxygen output and temperature output, a measured ratio of hydrogen to water within the furnace region and compares the measured ratio with the hydrogen/water ratio set point, and provides a correction signal output in accordance with a determined difference between the measured ratio and the ratio set point. A flow controller is responsive to the correction signal output to provide a flow of at least one of hydrogen and water to the furnace region to move the hydrogen/water ratio towards said ratio set point.
