Patent DE-3801895-A1 (DE)
Title: Device on the front end of a farm tractor for raising an additional weight carrier into a transportation position
Inventor: RATHKE GERD
IPC: B62D49/08
Filed: 1988-01-23
Abstract: For receiving additional weights to be carried along on the front end of a farm tractor use was hitherto made of conventional mounting devices for working implements, comprising two lower links and one upper link. For farm tractors which are not intended for use with front-mounted working implements, the known mounting devices appear disproportionally expensive. Accordingly, the novel device is to be used on a farm tractor specifically for receiving, carrying along and putting down additional weights and is to be of the simplest possible design. In order to achieve this, two links (5) are articulated on the tractor body (front axle block (3)) far to the rear at the bottom, catch hooks (6) are arranged on the links (5) in a manner known per se as receptacles for the additional weight carrier (14), the additional weight carrier (14) has above its bottom bearing surface, at a distance from the catch hooks (6), two laterally protruding coupling bolts (19) with a circular cross-section, and attached to the additional weight carrier (14) is at least one cantilever (15) which below the coupling bolts (19) reaches under a stop (tie-bar (13)) which is fixed onto the link and is situated in the path of movement of the cantilever (15). The device is suitable for receiving heavy loads at the front end of farm tractors. <IMAGE>

The plug socket (3) and the communication insert (5) are surrounded on the access side by a covering frame (6) which is held detachably on the upper part (2). The mains current region (7), which accommodates the plug socket (3) or plug sockets (3) and the plug connector (4), of the housing (1, 2) is electrically screened from that housing region (8) which accommodates the communication insert or inserts (5) by a partition part (9) which is inserted detachably into the housing (1, 2), is fixed in position therein and is made of insulating material. <IMAGE>

Patent DE-3814564-A1 (DE)
Title: Pivoting and/or sliding door for motor vehicles
Inventor: EBERWEIN HANS FRIEDRICH
IPC: E05D15/58
Filed: 1988-04-29
Abstract: Motor vehicles with only pivoting doors have disadvantages. They take up too much space in stationary traffic as a result of parking operations. Parking operations are often not without risk. More and more motor vehicles are coming onto the market. Available parking spaces are limited, expensive and no longer viable. (Z1). My invention affords an alternative. It becomes possible to get into and out of a vehicle in the most confined parking space. An improvement of 20 to 30 % to the parking possibilities existing at the present time is afforded. A change-over phase of 10 to 15 years would bring enormous advantages in economic and traffic terms. (Z1).  Technical solution: Sliding pressure cylinders are attached to the vehicle-frame part in place of the angular holding hinges. These cylinders press the vehicle-body door out by the amount of a door thickness. Two sliding rails are mounted on the interior door side of the vehicle at a distance from one another which is appropriate for the total weight. Rollers with sliding rods run therein. The sliding rods can be pushed into sliding rails which are mounted externally on the chassis. The mountings of the vehicle door on the sliding pressure cylinders are opened and released. The door can be pushed rearwards by means of a handle. The door is closed again by means of a reverse operation. Attention is drawn to subclaim S 3/6 - Z10 1f of the patent application. <IMAGE>

Title: Micromechanical acceleration sensor with capacitive signal transformation, and method for producing it
Inventor: BENECKE WOLFGANG DIPL PHYS DR
IPC: G01P15/125
Filed: 1988-07-20
Abstract: Micromechanical acceleration sensors are suitable for many applications, e.g. in air traffic, in space flight, robotics and in road traffic. The sensor is to be constructed as simply as possible for production in large batch-quantities. A description is given of an acceleration sensor having a torsion member and a differential capacitor arrangement which is assembled from only two elements. It is possible to dispense with a third element, which is otherwise customary, because the capacitors of the differential capacitor arrangement are arranged in one plane. This is achieved by attaching the movable electrodes to a surface of the torsion member in such a way that the capacitance of one capacitor is increased during acceleration while that of the other becomes smaller. The acceleration sensor is simple to produce using the methods of microstructure technology. <IMAGE>

Inventor: RIEDERER RUDOLF
IPC: B60J10/02
Filed: 1989-02-25
Abstract: In a window or windscreen arrangement on a vehicle body (11), the opening for the window or the windscreen (18) has a mounting flange (12) which is stepped towards the inside of the vehicle. The pane (18) is bonded in an edge region to a mounting flange component (13). Along the edge, facing away from the window opening or windscreen opening, of the mounting flange component (13), a slit seal (15) is bonded securely in position. The latter is formed by an elastically deformable hollow profile body which is continuous or of specific length, essentially corresponds to the circumference of the pane (18) to be bonded in, can be bonded securely to the mounting flange (12) and is enclosed on all sides. In addition to other technical and optical advantages, the use of the proposed slit seal (15) is substantially cheaper than conventional sealing or covering designs and covers the slit from below between pane (18) and mounting flange (12) reliably even given the presence of all the constructionally conditioned size tolerances.

Abstract: An etching installation contains an etching machine (1) in which the etching agent is enriched with metal that has been etched away during the etching process. The etching agent is regenerated in an electrolytic cell (11) by electrolytic enrichment in metal. The electrolysis inside the electrolytic cell (11) is controlled by a densimeter (26) which monitors the density of the etching agent leaving the electrolytic cell (11). If this density falls below a given value, the electrolytic cell (11) is deactivated, so that the current supplied by a direct current source (13) falls from an operating value to a low resting value at which the electrolytic deposition of the metal on the electrodes (12) is equal to or slightly greater than the chemical back-etching of the metal from the electrodes (12).
