Patent DE-4341428-A1 (DE)
Title: Textile dyeing process
Inventor: GRUENINGER GUNTER PROF DIPL CH
IPC: D06P1/653
Filed: 1993-12-04
Abstract: A textile dyeing process is claimed, in which the absorption and fixing of the dye takes place mainly at constant temp., using the extraction method with a time-dependent shift in the pH of the dye bath from a reaction-inhibiting initial value, and readjusting the used bath to the same initial pH (or a new value) so that the bath can be re-used. The time-dependent pH shift and readjustment of the pH of the used bath are both produced by contacting the bath with a controlled amt. of ion exchange material (I), and the salt(s) (II) required for prodn. of the necessary acid(s) or alkali(s) by ion exchange is/are added to the bath before the start.

Title: Minimising data loss when peripheral fault occurs - evaluating fault condition in peripheral, breaking off host computer command at peripheral, and interrupting internal operations of peripheral and reporting to host
Inventor: SHANNON CHARLES PATRICK
IPC: G11B19/02
Filed: 1993-12-09
Abstract: A data processing system has a host computer (6) and a peripheral (4) contg. a data buffer (8) for storing information to be transmitted or received over a bus (2). A wait loop routine unit (10) contains a list of instructions to control the read and write operations. When error functions are identified, the internal operations of the peripheral unit is interrupted. Data is saved into the buffer memory and the process recommences when the host computer generates the necessary signal. ADVANTAGE - Protects data within buffer when fault in peripheral occurs.

Title: Circuit to control speed of universal motor e.g for vehicle air conditioner
Inventor: HACKER KARL DIPL ING
IPC: B60R16/03
Filed: 1994-03-12
Abstract: A circuit to generate a PWM control signal for the speed of a universal motor uses a multivibrator made up from an inverting Schmitt trigger using a comparator (k1) and two resistances (r2, r3) coupled to a RC-circuit (r4,c).

Filed: 1994-04-19
Abstract: An electronically adjustable brake operating system for vehicles is proposed, with a brake master cylinder (2) which can be operated by means of an operating pedal (1), with brake pressure transducers (4-6) which can be actuated by an electronic control unit (3), wheel brakes (8, 10) being connected directly to the brake pressure transducers which can be connected, via hydraulic lines (11, 12) which can be closed off by valve devices (16, 17), to the brake master cylinder (2). There is also at least one sensor device (22, 23) to detect the driver's wish to slow down, and at least one simulator chamber (14, 15) which co-operates with the brake master cylinder (2). As an improvement to systems of this type, especially during anti-lock operation, it is proposed according to the invention that the valve units should take the form of solenoid valves (16, 17) which can be actuated by the electronic control unit (3), and that the pressure-volume uptake characteristics of the simulator chamber (14, 15) should be independent of the wheel brakes (7, 8, 9, 10).

Patent DE-4418120-A1 (DE)
Title: Vehicle pneumatic spring damper unit
Inventor: SCHNECKENBURGER REINHOLD DIPL
IPC: F16F9/02
Filed: 1994-05-24
Abstract: The unit comprises valves (14), between displacement chambers (5,6), which are controlled as a linear and/or non-linear function of the valve lift speed and/or spring travel. In this way, the valves open at low or decreasing pressure gradient at low valve fit speed but only under high pressure gradient at higher lifting speed. The valves open under a pressure gradient which increases with increasing distance from the centre position. The transfer channels (9) are controlled in part at least by valves, using magnetisable valve spring plates as shutoff. In this way, the plate co-operates with the contact surfaces (15,16) whose closing force depends on the variable electrical load applied to the magnet (17) whose flux (F) travels over the contact surfaces and valve plates (14). Otherwise, the valve closing force is controlled by a single electric magnet which works in parallel to a permanent magnet and sets up fields which are directed with or against those produced by the permanent magnet.

Title: Method for regulating a winding speed of thread-like material
Inventor: SCHEIBNER ACHIM
IPC: D01H13/10
Filed: 1994-07-13
Abstract: Method for regulating a constant winding speed of thread-like material. During the winding of thread-like material, the rotational speed of the spindle drive motor is to be lowered in dependence on the increasing package diameter, in such a way that the thread tension follows a predetermined value during the winding operation. For this purpose, the rotational-speed/torque characteristics of any number of different thread-tension curves and the idling/torque characteristic of the motor are filed in a microprocessor control. The microprocessor control calculates from the rotational-speed/torque characteristics of a specific selected thread-tension curve and the idling torque the total torque which is assigned to the respective rotational speed and which is imparted to the drive motor as a desired current value. The invention can be used on spinning, twisting or winding machines with an individual motor drive.

Title: Track-heating means (travel way-heating means) for transportation systems
IPC: E01H5/10

Inventor: KOTTENHAHN MATTHIAS
IPC: C07C215/02
Filed: 1994-09-03
Abstract: A process is disclosed for reducing amino acids and derivatives thereof. Compounds of formula (I), in which n = 0 or 1 and R<1>, R<2>, R<3>, R<4>, R<5> and R<6> have the meanings given in the description, are reduced to the corresponding amino alcohols of formula (II): the formula (I) compounds are converted in a first step, in at least one alcohol and with the addition of acid and heat, to an ester, this process producing a reaction mixture containing the ester; the ester is converted in a second reaction step with alkali or alkaline earth borohydride to compounds of formula II. By specifying that the second step be carried out without isolating the ester from the reaction mixture and by using alkali or alkaline earth borohydrides which are not activated, the invention facilitates the production from amino acids and their derivatives of the corresponding alcohols in a simple "single vessel" process, with high yields and in such a way as to preserve a given centre of chirality. Applications: synthesis components, preparation of optically active compounds, splitting of racemic compounds.

Title: Circuit voltage shifting method for e.g. analogue=to=digital converter
Inventor: DUONG PHUOC VAN DIPL ING
IPC: H03M1/12
Filed: 1994-11-07
Abstract: The method involves using a capacitor and a voltage supply different from the two voltages between which the voltage is to be shifted. The voltage value, e.g. the difference between two potentials, is shifted by coupling each potential to a pole of the capacitor with a given capacitance. The connection is interrupted after the capacitor has been charged up to a specified level, e.g. the charge equalling the difference between the two potentials multiplied by the capacitance. Then at least one capacitor pole is coupled to a further terminal at a third potential, and the voltage is tapped at both capacitor poles. Pref. the third potential is so chosen that the tapped voltage lies in a preset voltage region, especially in a working range of operational amplifier etc.
