Abstract: A dialysis membrane of cellulose regenerated from cuprammonium solns. is in the form of a hollow fibre with a continuous empty space. The fibre surface shows periodic variations in the longitudinal direction (e.g. comprising longitudinal waves) and/or in the peripheral direction. Thus the cross-section, perpendicular to the fibre axis, varies periodically over the fibre length. The membrane can be 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 as usual. The membrane is used partic. in haemodialysis. The efficiency of dialysis is increased owing to an improved exchange surface.

Patent DE-2920825-A1 (DE)
Title: Plasticising installation preparing extrusion and moulding synthetics - generates heat by friction and thrust in melting chamber
Inventor: WITTROCK LUDWIG
IPC: B29C48/38
Filed: 1979-05-23
Abstract: Powder form or granular synthetic material to be plasticised or injected for moulding, has imposed upon it a swirling motion, by the pressure of the feeder positioned in front of the melting chamber. The friction and thrust set up by the swirling motion cause the majority of particles to be raised to the melting or plasticising temp. and the mass is delivered to the mould or extrusion tools. The required working pressure for the frictional and thrusting action in the rotating stream of raw material is dimensioned so highly that, directly after the plasticised-grains of raw material are combined into a compact mass, they are delivered to the moulding or injection channels of the tools under a pressure a little below the working pressure. The rotary velocity necessary for the frictional and thrusting work is dimensioned so that the working heat corresponds to the quantity of heat required for the melting of the size of the stream of the raw material concerned. It is possible to dispense with the outlet compression pump called for in earlier publications. Restriction of the build-up pressure in the melting chamber to 5 bar is unnecessary.
Patent DE-2922687-A1 (DE)
Title: Burglar deterrent for unoccupied building - has interval timer in form of electrical device which switches lights, radio etc. periodically on and off
Inventor: POSCHMANN HORST
IPC: G08B15/00
Filed: 1979-06-02
Abstract: To deter burglars from entering an unoccupied building, the lights, radio, etc., are turned ON and OFF at intervals by a time switch. The timing circuit is a capacitor, charged through a variable resistor and discharged by an integrated circuit on reaching a threshold voltage. Each discharge steps a X128 counter, also in the integrated circuit. The IC output is alternately ON and OFF for 128 discharges; a time of 10 to 30 min., depending on the variable resistor setting. The IC output is connected to the emitter of a transistor whose base is in a voltage divider containing a light-sensitive resistor. Thus the transistor is turned ON and OFF by the integrated circuit at night, but not during daylight. The transistor drives a power transistor which drives a relay which switches mains to a socket.

Patent DE-2943635-A1 (DE)
Inventor: WUILLEMIN MAURICE
IPC: E01H4/02
Filed: 1979-10-29
Abstract: The lateral sides (8) of the pool (9) in which the ice is produced are of low height, 2 cm for example. The drainage channels (10) extend along the sides (8), the wall (11) separating the latter from the channels forming overspills. The result of this arrangement is that it is possible to clean the ice by sending water over the surface of the latter, the impurities from the ice which are detached by this hot water being discharged at the same time as the excess water which runs into the overspills in order to be discharged by the channels (10). Moreover, the thickness of the ice never exceeds the height of the overspills (8-11), regardless of the number of regenerations. <IMAGE>

Title: Reading subscriber telephone number into memory - by keeping entry button continuously depressed whilst selecting digits in turn on keyboard
Inventor: SCHUERGER RUDOLF DIPL ING
IPC: H04M1/27495
Filed: 1980-01-12
Abstract: The application is to subscriber instruments with digital key board and memory register for storing frequently used numbers. To read a number into the memory (SP) a special key, or entry button (Ta) is pressed and held down. The digits of the number to be stored are then entered by pressing the relevant keys (T1...TO) in turn. Normally the first digit gives the register address and the rest the telephone number. A processor, or control unit, (SE) supervise the key board. When the entry key and one other is depressed the desire to store a number is noted, the entry key signal briefly interrupted, and the digit placed into the register. To select a stored number for transmission into the network the entry key (Ta) is depressed and released, and then the appropriate register number key pressed. The processor then reads out and transmits the number pulses into the system. The proposed procedure is simple to follow, being very little different from normal dialling.
