Patent DE-4138256-A1 (DE)
Inventor: KETTELER KARL-HERMANN DR
IPC: B60L9/30
Filed: 1991-11-21
Abstract: Rail vehicles which are used internationally must obtain their drive energy from d.c. (1) and a.c. voltage systems with a different system voltage. A multi-system concept is disclosed which, with the fewest possible critical change-over operations and without power losses of the drive power is suitable both for a predeterminable a.c. voltage of for example 15 kV and for d.c. voltages of 1.5 kV and 3 kV customary for railways. For this purpose, the stator windings of an electric machine (11) are separated via a third switch (S3) into 2 current-conducting windings (MW1, MW2) with the same number of windings. A first sub-winding (MW1) can be connected via a second switch (S2) to alternating current terminals of a first power converter (2) which, when fed with 1.5 kV d.c. voltage, is connected in parallel on the d.c. voltage side with a second power converter (8). The second power converter (8) is connected on the a.c. voltage side to two sub-windings (MW2). When fed with 3 kV d.c. voltage, the two power converters (2, 8) are connected in series on the d.c. side via switches (S5, S6). When fed from an a.c. voltage system, the third switch (S3) is closed, the second switch (S2) opened and the first power converter (2) is connected on the alternating current side via a first switch (S1) to first and second secondary windings (SW1, SW2) of a power transformer (Tr1). <IMAGE>

Patent DE-4206748-A1 (DE)
Title: Used paper recycling
Inventor: DOERFLINGER HANS-DIETER
IPC: D21F1/70
Filed: 1992-03-04
Abstract: To process used paper, for recycling, a selective flotation is used for ink removal followed by at least one further cleaning flotation stage, using a multistage flotation for the selective flotation. The collected flotation foam is gathered together at the laest after the third flotation and cleaned in a total flotation through pressure relaxation. The foam, carrying impurities, is sepd. from the clear water and removed after further thicknening if required. The foam or sludge from the final first to third flotation stages or the second stage in a double flotation, is sepd. from the coarse dirt and fibres in one or two washing stages, and the fibres are further sepd. from the dirt. The fraction with a low fibre content is given a pressure redn. flotation to separate out the fine dirt. The fraction with a fibre content, and the clear water from the total flotation, are returned to a point in front of the flotation assembly.      With a double-stage sieve action, the coarse particles in the first fraction are mostly retained. The material with a fibre content is sepd. as a third fraction at the second stage and returned to a point in front of the selective flotation. The material contd. in the fourth fraction, together with the first fraction, is passed to the total flotation.

Title: Gas pressure regulation system, esp. for heating system - controls electromagnetically driven proportional valve according to actual load pressure using electronic controller
Inventor: HAERTEL GUENTER
IPC: G05D16/20
Filed: 1992-03-05
Abstract: The system includes an electromagnetically driven proportional valve (9) in a gas line and a load gas pressure sensor (16) downstream of the valve.  The sensor detects the actual load gas pressure. The corresp. signal is processed by an electronic controller (18) into a drive signal for the valve. A blocking valve (6) in the gas line (6,7) upstream of the proportional valve responds to the signal from the controller.  The proportional valve has a closure body (15) with a contour giving  an approximately linear increase in open cross-section with valve stroke. ADVANTAGE - Use of conventional electronic controller allows reduction in mechanical costs. Gives flexibility is setting control pressures.
Patent DE-4210216-A1 (DE)
Inventor: DUNGS JUN KARL DIPL ING
IPC: H01H47/00
Filed: 1992-03-28
Abstract: The invention relates to a monitoring circuit for computer-controlled safety devices. The monitoring circuit described here is an arrangement which initially holds safety-relevant loads switched off by means of a safety relay (K) until a self-test of the controlling computer has been completed within required time conditions. A holding capacitor (C1) is connected in parallel with the drive path of the safety relay (K), which holding capacitor (C1) can be charged via a charging circuit (R1, V1) when the safety relay (K) is in the quiescent position (Nc), and, after charging has been completed, moves the relay into the operating position, subject to simultaneous application of a drive signal from the microprocessor, only when specified connection conditions for the safety-relevant loads are met. A remanence relay can be used as the safety relay (K) for defect locking. The monitoring circuit according to the invention uses the difference between the pull-in voltage and the tripping voltage of the safety relay (K). <IMAGE>

Title: Synthetic peptides for neutralising the infectiosity of the AIDS VIRUS (HIV)
Inventor: PRIETO SANTIAGO ISIDRO
IPC: A61K38/00
Filed: 1993-06-22
Abstract: The invention relates to phenylalanine-containing peptides with the brief formula:  R1-aa1-Tyr-Ile-aa4-aa5-Val-aa7-aa8-aa9-R2, where the radical R1 corresponds either to a hydrogen atom or R3. The radical R2 corresponds to a hydrogen group or a group which is the same as or different from R3, where R3 is an oligopeptide which contains 2 to 10 amino acid residues; aa1 is Tyr or Phe, aa4 is Cys or Phe, aa5 is Glu or Phe, aa7 is Glu or Phe, aa8 is Asp or Phe and aa9 is Gln, Glu or a single bond between aa8 and R2, with at least one of the groups aa1, aa4, aa5, aa7 and aa8 being Phe. The preferred structures are those in which R1 = H and R2 = OH and in which the peptide is readily soluble in water. These peptides can be used for inhibition of the infectiosity of the AIDS Virus. These peptides have possible therapeutic uses, not only for the actual AIDS disorder but also for disturbing concomitant manifestations of AIDS. They could be useful for bringing to a standstill the advance of the disorder in asymptomatic HIV-seropositive people. Accordingly, they may be effective for prophylaxis of infection in people in risk groups who may possibly come into contact with the virus, and in the newborn children of seropositive mothers. These peptides can be prepared synthetically by the solid-phase method of Merrifield or by genetic engineering methods.

A coupling piece (13) is used to facilitate the coupling of the hose from the bath to the toilet cistern, with a connection for an alternative water supply. ADVANTAGE - Flushing system is economically and ecologically sound. It can be produced relatively simply, and shut off valve can be turned so that pumps can readily be removed. With defective electronic system, water can be taken from normal water supply line.

Filed: 1993-12-08
Abstract: In an air-curtain apparatus for doors, two circulating-air currents (14,15) rotating in opposite directions are produced with the aid of two blower devices (7,8).
