Patent number: 6563065Abstract: A method of adjusting an electrical switch arrangement comprising a pair of electrical contact members to a predetermined contact spacing is suggested. A first one of the contact members is associated with a first contact carrier and a second one of the contact members is associated with a second contact carrier. The first and second contact members are normally spaced from each other by the predetermined contact distance and are movable relative to each other across the contact distance. At least one of the contact members is displaceably held on the associated contact carrier. The contact carriers are moved towards each other across the predetermined contact distance. The one of the contact members is displaced relative to the associated contact carrier into physical contact with the other of the contact members. The one contact member is fixed in position on the associated contact member while physically contacting the other of the contact members.Type: GrantFiled: April 27, 1999Date of Patent: May 13, 2003Assignee: TRW Automotive Safety Systems GmbH & Co.

Patent number: 5108469Abstract: An exhaust-air purifying unit includes a housing, a first fan which is disposed in the housing and which draws exhaust air through the housing, and a heat exchanger which is disposed in the housing and which cools the exhaust air via heat transfer with a stream of cooling air which is drawn through the heat exchanger without contacting the exhaust air. A mechanical filter is disposed in the housing downstream of the heat exchanger, and a washing device is disposed in the housing upstream of the heat exchanger. The washing device sprays a washing liquid into the exhaust air as it enters the heat exchanger to remove harmful substances from the exhaust air.Type: GrantFiled: October 2, 1990Date of Patent: April 28, 1992Assignee: Behr GmbH & Co.Inventor: Michael Christ

Patent number: 5007180Abstract: In the case of a method of separating condensable harmful substances and solid particles from the process gas or used air from particularly a textile finishing plant such as for example a drier or a coating plant, for example in the paper or synthetic plastics industry, the used air is pre-filtered, cooled and passed through a mechanical final filtering apparatus. So that a considerable extent of separation from the used air is possible already at the pre-filtering stage, the warm used air is pre-filtered by being cooled to below the dewpoint of the condensable harmful substances and dispersed solid particles. The resultant condensate which contains impurities is extracted.Type: GrantFiled: June 12, 1989Date of Patent: April 16, 1991Assignee: Sueddeutsche Kuehlerfabrik Julius Fr. Behr GmbH & Co.
