Patent DE-3703019-A1 (DE)
Title: Safety device for a hydraulic regulating device for an aircraft part to be moved
Inventor: BEYER FRIEDER DIPL ING
IPC: B64C27/64
Filed: 1987-02-02
Abstract: A hydraulic regulating device of an aircraft has two independent fluid circuits, to which a separate piston/cylinder unit is allocated in each case as an actuator for one and the same part to be moved. Fluid under pressure is admitted to this unit in accordance with the position of an electromechanically actuated control slide. The control slide sits in a sleeve arrangement consisting of two sleeves spaced apart in the longitudinal direction. In normal operation each sleeve is held in a fixed position by an interlocking means. If the control slide jams in the one or the other sleeve, the relevant interlocking means is permanently released by instantaneously overcoming a predetermined force, so that the relevant sleeve together with the control slide is displaceable by a relatively small expenditure of force, and the fluid circuit allocated to the other sleeve is from now on the sole active component of the regulating device. At the same time as the release of the interlocking means, a bypass valve short- circuits the piston/cylinder unit of the circuit which is no longer active, so that this circuit sets no inhibiting forces against the regulating movements of the other circuit.

Patent DE-3710924-A1 (DE)
Title: Electronic device, intended in particular for installation in a vehicle, with a system for anti-theft protection
Inventor: BAUMGARTNER FRANZ XAVER
IPC: B60R16/02
Filed: 1987-04-01
Abstract: Previous electronic devices with systems for anti-theft protection have the disadvantage that, firstly, discharge times of capacitors with a high capacitance influence the response time of the anti-theft protection means and, secondly, servicing work on the vehicle which requires the vehicle battery to be disconnected can result in the device being inhibited. By means of the invention these disadvantages are to be avoided. In order to detect electrically the removal of the device from its place of installation, it is not the drop in the supply voltage but rather the difference in attenuation between when the power supply is connected and when it is disconnected which is evaluated. The field of application is high-quality entertainment electronics used in motor vehicles.

Title: Method for stopping an electrical drive at a specific angular position
Inventor: HOFSTAEDTER KURT DIPL ING
IPC: G05B19/23
Filed: 1987-10-07
Abstract: The electrical drive of a machine tool is kept at the operating rotation speed (UB) by correspondence between an actual rotation speed value (UI) and a predetermined required rotation speed value (US). If the command for stopping at a designation position (ZP) is given, then an idle base rotation speed (ULe) is specified (Position 0). The time is measured which it takes the actual rotation speed value (UI) to decrease by a specific percentage (Position 1), and the inertia of the loaded drive is calculated from the rate at which the rotation speed is reduced and the braking current (BS) used. This is used to calculate a load base rotation speed (ULa) and is immediately specified as the required rotation speed value (US). From this load base rotation speed (ULa), it is possible to stop the drive within 360@ in front of the destination position (ZP). Monitoring measurements of the inertia are carried out at Positions 2, 3 and 4. The idle base rotation speed (ULe) is defined in an analogous manner from the drive when it is loaded with the minimum possible inertia. This ensures that the system is driven to the destination position (ZP) at the maximum possible load base rotation speed (ULa), and that this position is reached in the shortest possible time. <IMAGE>

Title: Method for determining the luminescence of cell cultures, and device for carrying out the method
Inventor: WEIL WALTER DIPL BIOL
IPC: C12M1/34
Filed: 1987-11-06
Abstract: In a method for determining the luminescence of cell cultures, the latter are provided with a first substance which can luminesce and reinforces the natural luminescence and are subsequently treated by a second substance, which initiates luminescence, and the luminescence is detected photoelectronically. In this case, it is proposed to start by cultivating the cell culture to be inspected adhered to a carrier, and then to treat the carrier with a first substance capable of luminescence, to remove the first substance not absorbed by the cell culture adhering to the carrier, and to measure only the radiation emitted from the cell culture after the addition of the second substance, which initiates luminescence. The device for this purpose has a culture dish device, which can be screened from the environment and in which at least one carrier can be accommodated detachably under sterile conditions. In this arrangement, the at least one carrier which has been accommodated can be treated alternately with nutrient solution, washing solutions or substances capable of luminescence.

IPC: G06T11/60
Filed: 1988-05-04
Abstract: One of the most difficult problems in data processing is to subject the set of data to be processed, during input, processing and output, to an order, and to represent this order clearly. Representation of the data to be processed in table form is a usual way of achieving a certain clarity. In this case, the set of data to be processed is systematically assigned to the grid which is formed by the division and labelling of the table. Data items can be differentiated only by their respective positions within the table. The object of the invention is therefore to give a method and arrangement, by the use of which the data to be processed can be subjected to a much more detailed order, during input, processing and output. By the method according to the invention, the data to be processed is also shown in table form, but it is also possible to differentiate the data further and to show this on output. According to the invention, the data to be processed is divided into subsets, and membership of the various subsets can be recognised by assignment of different graphic symbols. Thus the user, during input and processing of the data as well as ... Original abstract incomplete.
