Patent DE-4129819-A1 (DE)
Title: Spring system for wheel support on motor vehicles
Inventor: RUNKEL WALTER
IPC: B60G11/26
Filed: 1991-09-07
Abstract: The hydraulic medium, during springing in and out, flows backwards and forwards via a hydraulic connection between the spring legs (2,4) and at least one hydro-pneumatic spring accumulator (22,20) contg. a compressible medium. The spring accumulator, by compression of the compressible medium, produces a hydraulic pressure, which affects the force of the spring legs via the piston activation (8).     During the springing out of the spring legs, two at least timewise varying hydraulic pressures prevail in the legs and in the spring accumulator, whereby the closure and opening of the connections (16,18) between the spring legs and the spring accumulator are automatically controlled by the difference in the hydraulic pressures (p1,p2) in the legs and the accumulator.

Patent DE-4137920-A1 (DE)
Title: Digital information transmission system with automatic data speed acquisition
Inventor: WILMOT STEPHEN B
IPC: H04L29/06
Filed: 1991-11-18
Abstract: Digital data are received in the input channel of a receiver, the validity of the data word is identified, and valid data are processed. When data are found to be invalid, a predefined cycle time interval is identified and an activity signal is checked. If the activity signal is identified as true, the momentary data speed status is identified and an opposite predetermined speed selected. If the activity signal is identified as false and the momentary data speed is low, the value of a low-speed timer is compared with a low-speed word-window. If the timer value lies outside the window, the momentary data speed status is changed to a higher speed.

Patent DE-4208578-A1 (DE)
Inventor: PARAMONOV VLADIMIR A
IPC: C23C2/00
Filed: 1992-03-13
Abstract: In a process for coating the surface of elongated materials, the materials go through a container for the molten coating material without reversing their direction. The container has a through channel surrounded by an electric field in which an electromagnetic force is generated and the dwelling time of the strip in the melt can be controlled independently from the strip advance speed. In order to improve the conventional strip coating process, so that favourable intermediate layers that ensure a good adherence and a good plasticity of the coating can be achieved, the molten coating material is continuously moved against the surface of the elongated material and is circulated in an atmosphere free from atmospheric oxygen while the hank-shaped goods so through the container. A device used therefor is characterized in that a pre-melting container (12) is associated to the coating container for the molten coating material (2), and that the melt (2) can circulate between the pre-melting container (12) and the coating container (1) in an atmosphere free from atmospheric oxygen.

Title: Device for measuring the mass of a flowing medium
Inventor: WOERSINGER JUERGEN
IPC: G01F1/684
Filed: 1993-04-01
Abstract: Known devices for measuring the mass of a flowing medium have two separate carrier apertures for receiving in each case a measuring resistor, in order to achieve the necessary minimum measuring wire length. However, this results in the disadvantage that the carrier body takes up a relatively large built-in length. According to the invention, two measuring wires (3, 4) connected to each other electrically are arranged inside a first carrier aperture (40) in a V-shape, behind each other in the flow direction (2) and offset transversely to the flow direction (2), in order to enable a relatively large measuring wire length, with the result that the device has a high measuring accuracy and takes up a low built-in length. The invention is provided for the measurement of the mass of a flowing medium, in particular for measuring the intake air mass of internal combustion engines (Figure 2). <IMAGE>
