Patent DE-3726764-A1 (DE)
Title: Hydraulic air cushion suspension with lateral and height stabilisation for loading
Inventor: FOERG GEORG
IPC: B60G17/04
Filed: 1987-08-12
Abstract: The suspension, side tilt and height stability in motor vehicles and especially in tractors is often very deficient. The tilt when cornering or on an incline is prevented by means of a pendulum (1), which stops the oil feed. A piston connected to the power lift can also largely prevent compression of the suspension. The height stability can be achieved automatically by a control valve or by an electrical unit. <IMAGE>
Patent DE-3731531-A1 (DE)
Title: Method for extending the resolution of a line camera or matrix camera
Inventor: PFEIFER TILO
IPC: G01B11/02
Filed: 1987-09-18
Abstract: The present invention relates to a method and a device for extending the resolution of a line camera or matrix camera having an electronic evaluation circuit. When the transmitted-light method is used to image a non-transparent object onto the semiconductor image recorder of such a camera and the grey values on a shadow edge are digitised, interpolation is carried out between the two pixels participating directly at this edge transition. Use is made for this purpose of an electronic evaluation circuit which consists of at least two parallel shift registers, a hardware processor (computing) circuit having storage (memory) locations and a clock generator. The result is an extension of resolution of a semiconductor camera by means of interpolation between those two pixels of the shadow edge transition of which the first is above a defined threshold value and the second is below, or vice versa. This interpolation is used to announce on the position of a shadow structure or on an arbitrary bright/dark distribution in a resolution which is above the spatial frequency of the image recorder. This calculation is carried out by means of a read-only memory in which a result is already filed for each possible input combination, so that then an interpolation can be performed in pixel phase.

Title: Hermetic refrigerant compressor in lifting-piston embodiment
Inventor: GUENTHER EBERHARD DIPL ING
IPC: F04B39/12
Filed: 1988-02-02
Abstract: The invention relates to hermetic refrigerant compressors and can be used in the construction thereof, in particular of those with relatively small capacity. Using the invention, a hermetic refrigerant compressor for domestic refrigerators is produced, which has a base part, in which a column is pressed in, on which the rotating parts are mounted. The crankpin for bringing about the lift is introduced directly in the rotor of the drive motor. The stator is mounted on the base part and at the same time is also used for resilient supporting bearing of the compressor block. The structure thus achieved according to the invention of the hermetic refrigerant compressor makes possible a low construction height which has previously not been achieved for comparable capacities. <IMAGE>

Patent DE-3921703-A1 (DE)
Inventor: HERMANN KLAUS-DIETER
IPC: G09F3/14
Filed: 1989-07-01
Abstract: The invention concerns a device for printing labels in a hand-held labelling appliance with a printing mechanism. The strip of labels passes over a guide edge at the dispensing point, at which point the label becomes detached from its carrier band and the carrier band is subsequently fed into a transport device for advancing the label strip. The invention consists in the fact that the label strip (12) used has individual labels (16), made of cardboard or a similar material, which are stuck to the carrier band (15) by means of an adhesive which, following separation of the label from the carrier band, remains on the band, or the adhesive residue remaining on the label after separation of the label from its support band (16) is not considered sufficient to cause any interference, or the adhesive loses its adhesiveness after separation from the carrier band. The labels can also be held on the carrier band by embossing.
