Patent DE-3832416-A1 (DE)
Inventor: CSOEKOER CSABA
IPC: B01D53/22
Filed: 1988-09-23
Abstract: The invention concerns apparatus for the separation of the constituent components of liquid solutions and gaseous mixtures, comprising a cylindrical housing 2 open at both ends and provided with a lateral inlet and/or outlet coupling 1. A capillary membrane bundle 4 is arranged in the housing 2 by being journalled in resin fittings 5, 6 which sealingly close the open ends of the housing 2. In order to realise more simply the orderly fixing of the membranes 4 and to enable a used-up capillary membrane bundle 4 to be readily exchanged the resin fittings of the construction according to the invention consist of a securing fitting 5 which gathers the ends of the capillary membranes 4 into an orderly bundle and a closing fitting 6 formed around the securing fitting 5 at the end of the housing 2. The closing fitting 6 is formed in a shape-locking manner with the internal wall of the housing 2 while at the same time being axially relatively displaceable in relation to the housing 2. The sealed closure of the housing is assured by a sealing ring 3 seated in an annular groove 11 formed in the internal wall of the housing 2 between the closing fitting 6 and the internal wall of the housing 2.   <IMAGE>

Title: Method for controlling the program for washing machines and program control for carrying out the method
Inventor: LUTHE WINFRIED
IPC: D06F34/28
Filed: 1988-12-24
Abstract: In drum-type washing machines, essentially two different machine types, the so-called front loaders and the so-called top loaders, are in use at the present time in the European sector. These washing-machine types have an electronic program control with a microcomputer. Depending on whether a top loader or front loader is used, a different program sequence is required. So that the program control can be used for both washing machines without appreciable changes, the program-control device possesses at least one machine-specific signal input, the activation of which is monitored by the microcomputer. As a result, the program-control device can be programmed automatically for the respective program sequence as a front-loader or top-loader machine.
