Patent DE-3418599-A1 (DE)
Title: Lifting pump drive, especially petroleum rod pump
Inventor: HOCHSATTEL SIEGMAR-J
IPC: F04B47/08
Filed: 1984-05-18
Abstract: In order to drive a rod pump, especially a petroleum lifting pump, a secondary power-control drive system is provided according to the invention, which comprises at least one hydrostatic machine working as a motor or as a pump for driving the pump cylinder and a further hydrostatic machine, which is linked to the first machine and which has an adjustable absorbing volume or output volume and is connected to a hydraulic accumulator and a driven pump. By means of setting the angle of traverse of the adjustable machine, the lifting and lowering movement of the pump is effected, pressure medium being withdrawn, for the purpose of lifting, from the accumulator in addition to the pressure medium quantity supplied by the driven pump, while during lowering, pressure medium is conveyed into the accumulator. Thus provision is made for recovering pump drive energy. As the driven pump runs continuously, conveying pressure medium into the adjustable machine during lifting and conveying pressure medium into the accumulator during lowering, the power input is reduced considerably.

Title: Method for determining the provision value of electrical energy and means for carrying out the method
Inventor: LEVACHER FRIEDRICH KARL DR
IPC: G01R11/64
Filed: 1984-06-19
Abstract: To determine the provision/chargeable price, the electricity supply undertakings currently use non-electrical values. Efforts are being made to change this and to use the consumed electrical energy or, for example, the maximum 100-hour value of the energy consumption registered within an annual reading period as a measure. To carry out the method, a mechanical version is provided in which the electrical measuring pulses coming from a standard meter (1) are used for controlling a recording instrument (7). In an electronic version, these measuring pulses are output to a microprocessor (21) where they are processed further in such a manner that the maximum value of the energy of the individual measuring periods consumed during a reading period can be read on a digital meter (22). <IMAGE>

Title: Welding press for body parts
Inventor: BAUST HANS
IPC: B23K11/31
Filed: 1984-09-20
Abstract: The invention relates to a welding press for body parts or similar sheet-metal components, having a transport slide which executes a reciprocating motion in accordance with a defined time law and can be driven hydraulically by way of a hydraulic motor. The latter is supplied with fluid via a proportional valve. The proportional valve, for its part, is controlled from an electronic control system which contains a computationally optimised control curve which is stored in a memory component and is read out as a function of travel. The proportional valves are thus controlled as a function of travel in accordance with a non-linear control law. A considerably better configuration of the sequence of motions in terms of time and as regards its dynamics and the ability to change it at the control panel is possible as a result.

Title: Satellite radio wave receiving device
Inventor: SAKURAI TAKASHI
IPC: H01Q1/32
Filed: 1985-06-26
Abstract: A satellite radio wave receiving device is described for a vehicle such as a motor vehicle. The signal with the maximum level is selected from output signals for a satellite radio wave which is received by a group of antennas with at least three directional antennas such as microstrip line antennas. Alternatively, the phases of the reception output signals of these antennas are set in such a way that a maximum output level of the receiving device is achieved. The direction of incidence of the satellite radio wave in relation to the direction of travel of the vehicle is determined from the combination of the levels or phases of the reception output signals of the antennas.
Patent DE-3530681-A1 (DE)
Inventor: BECKER GUENTER DIPL PHYS
IPC: B28B17/00
Filed: 1985-08-28
Abstract: The production of mouldings, for example concrete blocks, with uniform bulk density and accurate dimensions is achieved by measuring the block height and weight of the demoulded mouldings and by calculating the bulk density from these two values. If variations from the desired values occur, the filling level is immediately altered. Both measurements are carried out outside the vibration area so that precision measuring instruments can be used. To eliminate the influence of different board heights, the board upper side and the block surface is sensed and the difference determined. The procedure for determining block weight is such that the board with the blocks thereon is weighed and the known board weight is subtracted as the constant.

Patent DE-3539900-A1 (DE)
Inventor: KLOECKNER JUERGEN
IPC: B21C47/06
Filed: 1985-11-11
Abstract: The device serves to control the desired lifting and pressure-containing movements of strip pressure rolls for the reels which serve to store hot rolled strip. These reels have a rotating mandrel. The pressure rolls are actuated by piston and cylinder units for positioning the rolls electro-hydraulically in conformity with signals which indicate the relative position of the leading strip edge which rotates with the mandrel. The positioning of the roll, by the lifting and pressure-contacting movements, is effectd by position control with subordinated pressure control in a closed-circuit position control loop and a closed-circuit pressure control loop, by input of a setpoint position value which corresponds to the respectively prevailing pressure-contacting and lifting position of the pressure rolls, and by establishment of limited setpoint pressure values for both functions or directions of movement.

Title: Method of dividing plates into individual sizes by means of a plate-dividing unit as well as a device for carrying out the method
Inventor: JENKNER ERWIN
IPC: B27B5/06
Filed: 1985-11-14
Abstract: A method is described by means of which crude plates can be divided into a head part and a residual plate and one of these plate parts or both plate parts can be divided into strips or into a multiplicity of individual sizes by separating cuts made at right angles to one another. For the complete dividing of the head part already present in strips by separating cuts to be made at right angles to the longitudinal direction of the strips, manual turning of the head part through 90 DEG  in its supporting plane can be avoided here if the head part divided into strips is fed after its initial dividing into strips to a further saw in a direction parallel to the longitudinal direction of the strips and is again cut up at right angles to the longitudinal direction of the strip.
