Patent DE-3739271-A1 (DE)
Inventor: UEBEL HELMUT DIPL ING
IPC: G01C22/02
Filed: 1987-11-20
Abstract: This device comprises a system evaluating the rotations of the wheels, a system operating contactlessly on the basis of the Doppler radar or in accordance with an optical correlation method and an inertial acceleration measuring system. The three systems mutually supplement and correct themselves. This makes it possible to measure distance and speed with sufficient accuracy even during operating conditions which cause wrong measurements of individual measuring systems, for example during sliding or spinning of the wheels, when travelling on an inclined path, with strong snowdrift or when driven with regulated wheel slip. For this purpose, the signal of the accelerometer (BM) is supplied to two evaluating channels (AK1, AK2) where it is corrected as a function of the operating state found by a slip detection circuit (SE1) or a detector (SE2) for wrong measurements, by the values derived from the measurement of the wheel-dependent system (RA) or of the contactlessly operating system (WG). After double integration, a computer (R) selects the evaluating channel from which the distance or speed signal is taken for further processing. <IMAGE>

Title: Electronically controlled piston dosing pump
Inventor: DIETER HAGEN W
IPC: F04B49/06
Filed: 1988-01-16
Abstract: In known piston dosing pumps, the piston is controlled or moved by means of mechanical lifting drives, such as cranks, cams, eccentrics etc. In the case of this kind of drives, only a few parameters are adjustable and even then only in an inconvenient and time-consuming manner. The purpose of this application is to provide a remedy in this respect. To this end, a combination is produced, consisting of a newly developed software package, electronics with a microprocessor, a positioning motor and a reversing motor, which is integrated with a system of input switches. As a result, necessary entries or modifications thereof can for the first time take place by means of simply pressing a button. Entries and adjustments, which previously often caused much time outlay, can now be carried out electronically in seconds. The profitability of the machine is thus increased considerably.

Title: Process and apparatus for filtering and percolating rainwater
Inventor: STAHN ROLF
IPC: E04D13/08
Filed: 1988-06-27
Abstract: In rainwater and/or combined-water ducts in residential-area water management, large duct cross-sections have to be made available for rainy weather. In order to achieve a reduction in the duct cross-sections, a process and an apparatus for filtering and percolating rainwater is presented here. In this arrangement, soiled rainwater is conducted into a filter, which retains coarse matter, before it passes, in a largely mechanically cleaned state, via water-permeable elements into the absorbant underlying surface (subsoil). In the event of the filter being overloaded or blocked, the water discharge takes place via an emergency overflow.

Title: Restrictor chamber discarding sabot
Inventor: BONGERS HERMANN DIPL ING
IPC: F42B14/08
Filed: 1988-07-26
Abstract: In order to achieve a minimum discarding sabot weight in the case of a predetermined load on a discarding sabot which is generally divided into three segments, the discarding sabot is designed as a hollow body. In order that the gas force which acts on the discarding sabot during firing is distributed over a large number of points, passage openings are incorporated in the rear wall of the discarding sabot, through which opening part of the powder gases flows into the interior of the discarding sabot, the restrictor chamber. If the discarding sabot is divided by one or more intermediate walls in the axial or longitudinal direction in order to increase stiffness, then the intermediate walls likewise have passage openings. On firing, the powder gases then flow through the intermediate walls to the region in front of the end wall of the discarding sabot. During firing, the gas force is transmitted from the end wall and rear wall of the discarding sabot to the projectile. In the case of discarding sabot designs having one or more intermediate walls, the gas force is further subdivided while being transferred to the projectile.

Patent DE-3929229-A1 (DE)
Inventor: KNEISEL DIETMAR
IPC: H01R13/66
Filed: 1989-09-02
Abstract: The invention relates to an electrical installation apparatus, especially a safety socket. This installation apparatus has a supporting ring with retaining webs which hold a base of insulating material. The electrical connecting contacts, the earth clip and, if applicable, mechanical retaining elements and the like, are accommodated thereon. A board having overvoltage protection elements is also allocated to the insulating material base. The effectiveness of the overvoltage protection elements is indicated by means of a signalling device. The electrical installation apparatus also includes an insulating material housing which at least partially surrounds the insulating material base. This insulating material housing, together with the parts located inside it, is accommodated in the interior of a retaining socket, especially a flush-mounted socket. While the signalling device for indicating the effectiveness has in the past always been constructed as an optical signalling device it is now proposed to use an accoustic signalling device. This may consist, for example, of accoustic signalling devices of the type known under the designation "buzzers". In order to facilitate economical production of the electrical installation apparatus, it is provided for the insulating material housing to be fixed to parts of a commercially available electrical installation apparatus, which exists in any case. This can take place, for example, in such a manner that the insulating material housing is attached to the retaining webs of the supporting ring of the installation apparatus. <IMAGE>
