Title: Vehicle seat
Inventor: CREMER HEINZ P
IPC: B60N2/90
Filed: 1987-10-20
Abstract: The invention relates to a vehicle seat with at least one pneumatic seat-shaping element (4) which has at least two chambers (5, 6) which are arranged between the cushion (3) and the cushion support (2), can be deformed elastically, can be filled with a selectable air pressure and are each in the form of a flexible tube closed at its two ends. The chambers (5, 6) are arranged in such a manner that one chamber (6) transmits the force which is exerted on it by the cushion (3) to the other chamber (5) which is supported against the cushion support (2). The two chambers (5, 6) are connected to an adjusting element (7) which engages between them and is arranged such that it can move between the cushion (3) and the cushion support (2) in a direction running transversely to the longitudinal axis of the chambers (5, 6) connected to it, this movement causing the chambers (5, 6) to uncoil.   <IMAGE>

Patent DE-3809741-A1 (DE)
Title: Computer system for mining equipment of an underground operation
Inventor: HELBING HUGO DIPL ING
IPC: G05B15/02
Filed: 1988-03-23
Abstract: Mining equipment, such as shearer loaders and selective-cut heading machines, is equipped with a large number of transmitters, sensors, relays and solenoid valves, the measured values of which are recorded and displayed by a computer, or which are controlled by a program of the computer. The number of these components, which are distributed over the whole machine, makes the installation of such computers difficult because of the lines which are required, and costs building space, which is only available to a limited extent in mining machinery which is used underground and therefore of compact construction. A computer system which is equipped with a central computer (1), which contains the whole program for control and data transmission of such machines, is proposed. It is connected via serial data bus lines (3) to a number of remotely programmable satellite computers (2, 2a), which each independently monitor and/or control one of the mining items of equipment, or a part or parts of it. <IMAGE>

Title: Process for filling a manually-operated pipetting device and apparatus for carrying out the process
Inventor: WANNER JUERGEN
IPC: B01L3/02
Filed: 1989-02-03
Abstract: A process for filling a manually-operated pipetting device in which a piston provided to be able to slide in a cylinder of the device is first manually pushed against the force of a return spring into a filling starter position for reducing the volume of the cylinder and is returned by the force of the return spring to a noncompressed pipetting start position to fill the pipette tip applied to the pipetting device is to be improved in such a manner that contamination of the piston seal by pipetting liquid is avoided. For this purpose the filling return movement of the piston initiated by the spring force is retarded and damped over the first piston stroke return section in comparison with the remaining piston stroke in the region of the filling starter position.
Patent DE-3903579-A1 (DE)
Title: Device for detecting changes in rotational speed
Inventor: WAGNER FRIEDRICH ERNST DR ING
IPC: G01P3/40
Filed: 1989-02-07
Abstract: In order to measure changes in rotational speed of rotating parts (2), marks (3) are applied to the latter and are illuminated intermittently by means of a light source (4) at a frequency of (f). The image of the marks (3) impinges on two photodetectors (10; 10') which are connected in a differential connection. The light source (4), the photodetectors (10, 10'), a signal processing unit (11), a controller (12) and a square wave generator (13) together form a control loop. The frequency (f) is controlled in such a way that a permanent image of the marks (3) impinges on the photodetectors (10; 10'). An evaluation device (15) measures the frequency (f) at fixed time intervals and stores the measured values. The current value of the frequency (f) is compared in this case continuously with the last measured value. The difference in the frequencies (f) between two measurements is displayed in a display unit (16) as a change in rotational speed. In the case of a drive with a constant torque, a change in rotational speed is equivalent to a change in friction. The device is used, in particular, to measure friction at roller registers of electricity meters. <IMAGE>

Title: Service-installation-floor system
Inventor: WAGNER HANS
IPC: E04F15/024
Filed: 1989-02-14
Abstract: Up until now, in the case of service-installation-floor systems of the generic type, the positionally correct fitting and fixing of the load-bearing supports (20) of the substructure on the basic floor (14) has been high in terms of outlay, and time-consuming. The object of the invention is to design a service-installation-floor system of the generic type such that shorter assembly times and simpler handling during assembly are obtained. This object is achieved by using mounting rails (32, 34) which are provided with cutouts (36) which are arranged at unit spacings from one another and through which the feet (22, 24) of the load-bearing supports (20) pass with a fit clearance and which fix the load-bearing supports (20) at the predetermined unit-space locations.   A preferred application area is constituted by service-installation-floor systems for offices. <IMAGE>
