Title: Dialysis membrane comprising hollow cellulose fibre - with improved exchange surface, extruded from cuprammonium soln. of cellulose
Inventor: BANDEL WERNER DR
IPC: D01D5/24
Filed: 1978-11-09
Abstract: A dialysis membrane of cellulose regenerated from cuprammonium solns. is in the form of a hollow fibre with a continuous empty space and a closed lateral surface. In a cross-section perpendicular to the fibre axis the difference of the distances of the lateral surface and of the boundary of the aperture varies each time from the centre of the fibre, over the circumference of the lateral surface. The membrane is mfd. by extrusion of a cuprammonium soln. of cellulose into an aq. caustic soda soln. through the annular slit of a hollow fibre die immersed in the aq. caustic soda soln. A liq. which will shape the empty space is extruded through the inner passage of the die. The ratio of the speed of drawing of the hollow fibre over the first drawing roller to the speed of extrusion of the cuprammonium soln. of cellulose from the annular slit is 1-1.05. The direction the fibre follows from the die to the first drawing roller forms an acute angle, pref. 15-70 degrees, with the axis of the die apertures. Subsequent treatment of the fibre is conventional. The membrane is used partic. in hemodialysis. The efficiency of dialysis is increased owing to an improved exchange surface.

Title: Time interval marker for telephone system data processor - transmits pulses on one cable core to the processor store in system evaluation
Inventor: BREKER KARL-HEINZ
IPC: H04M3/36
Filed: 1980-03-29
Abstract: The interval or timing marker is used in a telephone system data processor as set out in Patent 2321124. Such a processor is used in system investigation into peak loading and allied parameters. The purpose of the time interval marker is to assist in evaluating system performance and loading over discrete short time intervals. The marker pulse generator (E) is connected to one core (c) of a telephone line. It simulates the line engaged condition for a set interval which is timed such that the data processor recognises this pulse as a time marker and not a legitimate call. The generator is driven by an oscillator and counter (TG,Z) which, trough a suitable programme (PF) controls the state of a flip flop (FF) which gives the engaged pulses. The unit (E) may be incorporated in the processor. By knowing the instant of starting the pulses, the time at which various systems loading occur can be determined by counting marker pulses from the known start pulse.

Title: Identifying receiver lifted condition of subscriber instrument - by measuring increase in direct current and filtering out tone frequencies in subscriber circuit
Inventor: ALBERS RAYMUND DIPL ING
IPC: H04M3/22
Filed: 1980-04-23
Abstract: The d.c. source (UB) is connected to the subscriber lines (a,b) through two equally sized resistors (R1,R2). To the subscriber appts. (T) side of one resistor (R2) a voltage divider (R3,R4) is connected. From its tapping point connections are taken to a summing junction (A); one directly and one through a phase inverting filter (F). The summed output of these signals is applied to a level detector (E) whose output in turn is passed to the telephone exchange control circuits (A,St). The filter (F) passes operational tone frequencies, e.g. calling tones and frequencies associated with dialling, and phase inverts these to give a cancelling effect in the summing junction. By eliminating these alternating components superimposed upon the d.c. in the subscriber line the recognition of the receiver lifted condition is made more certain.

IPC: F02M61/20
Filed: 1981-02-21
Abstract: A fuel injection valve contains a first compression spring (7) and a second compression spring (11) in its nozzle holder (1). Injection is performed in two stages: lifting of the nozzle needle (4) by the initial injection stroke causes compression of the first compression spring (7) alone and subsequent lifting of the nozzle needle (4) in the main injection lift causes compression of the second and the first compression spring (11 and 7). The first compression spring (7) is supported on a first movable spring seating element (6), which is connected to the nozzle needle (4). The second compression spring (11) is supported on a second movable spring seating element (9), which engages with a stroke adjusting element (10) which is provided with a thread and screwed by this into the nozzle holder (1) in order to permit axial adjustment relative to the latter, and this axial adjustment causes a corresponding axial adjustment of the second movable spring seating element (9). This makes it possible to adjust the gap ( DELTA @) between first and second spring seating element (6 and 9) in a range which lies between zero and a predetermined value which determines the abovementioned initial injection stroke. <IMAGE>
