Patent DE-4139998-A1 (DE)
IPC: H01H1/023
Filed: 1991-12-04
Abstract: There are various processes for making such silver contact bases which, however, are either very laborious in the manipulation of the silver contact base and intermediate layer, the contact plate and the contact bearer and their soldering or are based on strip material of suitable composition, rolling these strips on one another and cutting the edges. In the latter process, noble metal is wasted. To avoid these drawbacks, according to the invention the solder is applied in the form of a platelet (6) before the actual process on the intermediate silver layer (4). Here it is especially advantageous if this application is made by ultrasonic soldering. The invention is applicable to all silver contacts.

Title: Mercerisation of textile material e.g. cotton cloth - utilises aerosol impregnation to spray the lye under steam pressure, satn. and stabilisation, to reduce time and space
Inventor: MEISEN KLAUS
IPC: D06B7/08
Filed: 1992-01-21
Abstract: Mercerisation for textile material includes use of an impregnating zone for the caustic, which is then allowed to saturate and stabilise, followed by at least partial extraction of the lye. The impregnation is by an aerosol process with a saturation time of half that of the stabilisation. The cotton fabric (1) is pref. guided by rollers through the equipment (2) in which the caustic lye is projected under steam pressure into the cloth by an aerosol process (A). The second stage (B) is pref. to regain width on the rollers (4) and in stage (C) the cloth is allowed to relax in a saturated state, for a relatively short time. The cloth can opt. be taken along the stenter (5) with grips or pins (22) to draw the cloth into shape as it is stabilised in stage (D). ADVANTAGE - The impregnation is more reliable and thorough by the aerosol injection process than in steeping. Both time and space are saved, resulting in a more economical process
