Title: Capillary pore membrane based on hydrophilic polymer film
Inventor: LUECK HANS B DR SC NAT
IPC: B01D67/00
Filed: 1995-09-28
Abstract: Capillary pore membrane (CPM), consists of a hydrophilic polymer film (HPF) in which the pores are the etched-out tracks formed by irradiation with high-energy particles, and in which the outer surface of the membrane and the walls of the pores are coated with a hydrophobic coating (HC) which is thinner than the pore radius. Also claimed is a process for the prodn. of the CPM by (a) irradiation of HPF with high-energy particles, (b) widening the particle tracks with a suitable etchant to form continuous pores, (c) neutralising the etching agent and (d) washing and drying the membrane obtd.   Before or after drying, the washed membrane is treated with an emulsion of waterproofing agent until this penetrates completely into the pores, and is then dried, formed and fixed on a thermostatically heated forming surface.

Patent DE-19602363-A1 (DE)
Inventor: KOHL ANDRES
IPC: B60T8/40
Filed: 1996-01-24
Abstract: A brake pressure control system is proposed which works on the fluid-return principle. This system contains a low pressure accumulator (9) which must be emptied at the end of a braking action with brake pressure control. For this purpose the pump (12) is controlled for a certain time. In this emptying phase, the motor (13) is controlled by pulse-width modulation. During the phases of the control signal during which no voltage is applied to the motor (13), a measurement of the electromotive counterforce is performed. This counterforce is a measure of the speed of the motor (13) or the speed of the connected pump (12). If the speed or the change is speed exceeds a given value, then this can be accepted as an indication that the low pressure accumulator is empty. As soon as such a signal appears, the emptying phase is ended by switching off the motor (13). In this way the emptying phase is kept as short as possible.
