Patent DE-3810250-A1 (DE)
Inventor: BRACKER GERD-PETER DR ING
IPC: C12M1/00
Filed: 1988-03-23
Abstract: A process for the two-stage anaerobic treatment of liquid substrates with a high organic content in a reactor (1) with two inter-connected chambers (3,4), in the first of which the hydrolysis and acid fermentation (fermentation chamber) takes place and in the second of which the methane digestion (digestion chamber) takes place, the substrate being introduced into the lower region of the digestion chamber (5) and the sludge arising from the decomposed organic materials being discharged separately from the waste water element of the treated substrate (6, 12) and the fermentation gas and the biogas which have been formed being drawn off above the liquid level (8, 13). In order to further develop a process of the generic type in such a way that the whole process of substrate treatment is accelerated and, furthermore, to create equipment for the carrying out of this process which is constructed as simply as possible and, with respect to the optimum capacities of the fermentation and digestion chambers, can be easily adapted to existing circumstances, that is to say, the degree to which the substrate to be treated is loaded with organic matter, it is proposed that the substrate is fed to the two chambers in accordance with the discharge principle at about one third of the height of the relevant liquid level or lower and that the substrate is withdrawn from the fermentation chamber from above (14). <IMAGE>

Title: Injection device with drug depot
Inventor: LINSS WALTER DIPL ING
IPC: A61M5/315
Filed: 1988-04-26
Abstract: The invention relates to an injection device with drug depot, especially for insulin, on the ball point pen principle, with which two insulin units can in each instance be injected by pressure on a button. A tubular piston rod that moves the syringe piston is arranged so as to be longitudinally movable in the rear part of the cylindrical housing and has several circumferential grooves, which correspond to the number of metering steps, with profiles representing isosceles triangles. The follower sleeve provided with bores uniformly distributed over the circumference can be displaced longitudinally on the piston rod. Pins whose end facing the piston rod represents a truncated cone with an apex angle corresponding to the basic angle of the grooves are inserted in the bores. In the top region of the push-tube there is a conical bore which engages with the pins during the metering process and has an angle of inclination that is slightly larger than the flank angle of the grooves on the piston rod.

Title: Boring machine with a turning tool fastened in a holder rotating about an axis, and method of operating this boring machine
Inventor: BATHEN ROLAND
IPC: B23B29/034
Filed: 1988-06-03
Abstract: It is sometimes desired to produce bores with any polar and/or axial generating-line profiles, it being possible to restrict the generating-line deviations within relatively narrow limits of a maximum of up to about 0.5 mm in diameter. Non-circular bores of this type can be made with a precision boring machine in which the holder (4) or the work spindle (1) or a special holding device (10) arranged between turning tool (5) and work spindle (1) is designed to be articulated in the infeed direction of the turning tool (5). The articulated action can start from a material constriction (6) in the holder (4) or in the work spindle (1) or can be obtained by a pivot joint (11). The requisite deflection of the turning tool (5) is effected by electromagnets (7, 8). The magnitude of the infeed force of the magnets produces a position-control circuit in which the actual values, measured by an acceleration transducer (9), of the respective position of the turning tool (5) are utilised together with preset desired values by a corresponding comparison. <IMAGE>

Abstract: Machine for the discharge of granular material, which has a supply container equipped with outlet orifices and metering wheels of adjustable rotational speed, divided into groups, drivable in rotation via drive shafts and to be rendered ineffective in groups by an interruption of the drive, for conveying the material streaming out of the outlet orifices into pipelines connected to a blower and provided with outflow orifices, the material being fed from the metering wheels of each group to at least two pipelines for producing a spreading strip, and a spreading width of a spreading fan produced by the material flowing out of the pipelines amounting to a multiple of the width of the supply container, the metering wheels being divided into groups and the drive of the metering-wheel groups being disconnectable separately via couplings. In order substantially to improve field-edge spreading, provision is made for the metering-wheel groups disconnectable separately from the drive to be divided in such a way that one of the separately disconnectable metering-wheel groups is assigned solely to the outlet orifices located in the width region of the supply container or of the middle part of the machine and to the region spreading over the region of the machine, whilst the remaining separately disconnectable metering-wheel groups are assigned solely to the region not spreading over the region of the machine.

Patent DE-3903930-A1 (DE)
Title: Vehicle brake system for towing vehicles
Inventor: SCHLICHENMAIER ANDREAS DIPL IN
IPC: B60T8/17
Filed: 1989-02-10
Abstract: The brake system has an anti-lock device with an electronic control unit (3) for monitoring the road adhesion of the vehicle wheels. It is also equipped with a yaw-moment attenuator (9) which is controlled by the control unit and which prevents an excessively large difference in the brake pressure on the two sides of the vehicle in the case of widely differing adhesion values. When driven on their own, towing vehicles, particularly semi-trailer tractors, are difficult to control during braking on a differing road surface because of the large yaw and steering moments. The towing vehicle is therefore equipped with a trailer recognition unit (7), the signal of which can be evaluated in the control unit (3) and fed to the yaw-moment attenuator (9) as a controlled variable. When the towing vehicle is driven on its own, this signal allows the yaw-moment attenuator (9) to be controlled in such a way as to reduce the difference in brake pressure. <IMAGE>

Filed: 1989-10-25
Abstract: An adjustment circuit (17) positions the clutch driver (17) in accordance with the deviation of the actual value (n) of engine speed from its desired value (n). The output of a porportional-integral controller (25) is modified by a perturbation signal (sn) dependent on the temporal variation of the actual-value signal (n) to counteract speed changes. The desired value (n) is derived from a characteristic converter   contg. a nonlinear relationship (33) to the position (alpha) of the accelerator pedal (9), or alternatively from a device (35) differentiating this position. ADVANTAGE - Comfort of clutch engagement is increased without oscillations in control system.

Patent DE-4009304-A1 (DE)
Inventor: MEINDERS HORST DIPL PHYS
IPC: H03K17/08
Filed: 1990-03-23
Abstract: A short-circuit resistant transistor final stage, in particular an ignition final stage for motor vehicles, has a power transistor (10) connected in series to a consumer (12) and a blocking device that disconnects the power transistor (10) when a short-circuit occurs at the consumer. Means (23') for detecting a voltage drop at the consumer are connected to the consumer (12). A switch transistor (27) controllable through these means and linked to the base of the power transistor (10) applies to the base of the power transistor a potential that blocks the switching section of the power transistor below a predeterminable, very low voltage drop at the consumer that defines the occurrence of a short-circuit. The power transistor (10) is thus reliably disconnected in the event of a short-circuit and reliably remains in the disconnected state.
