Patent DE-3149700-A1 (DE)
Title: Coupling connection between a towing vehicle and a trailer, preferably single-axis trailer
Inventor: KOBER KURT
IPC: B60D1/173
Filed: 1981-12-15
Abstract: In normal towing vehicle-trailer combinations consisting of a towing vehicle (1) and for example a caravan (4), the so-called swinging movements of the trailer (4) have a disturbing effect on the driving behaviour of the towing vehicle-trailer combination (1, 4). With the invention, it has been recognised that this influence can be substantially reduced by displacing the effective coupling point (14) in the direction of the centre of gravity (29) of the towing vehicle (1) without changing the distance between the trailer (4) and the towing vehicle (1). However, since this position of the effective coupling point (14) is not accessible for constructional reasons, the invention proposes bridging by means of gearing the previously customary spherical head coupling (6) located at the rear of the towing vehicle (1) by connecting two joints (8, 9), which are associated with the towing vehicle (1), to two joints (10, 11), which are associated with the trailer (4), via links (12, 13) in order to form a four-link chain (8 to 14), the links (8 to 11) being arranged in such a way that the straight lines running through the links (8, 10 and 9, 11 respectively) in the longitudinal direction intersect at the desired effective coupling point (14). <IMAGE>

Title: Process for self-cleaning of a surface filter and self-cleaning filter device
Inventor: STUEBLE HELMUT ING GRAD
IPC: B01D46/24
Filed: 1982-04-06
Abstract: A process for self-cleaning of a rotatable surface filter and a filter device for carrying out the process are described. In order to be able to clean the surface filter in a simple manner with the lowest possible operating costs, it passes through a chamber in which the filter cake is mechanically scraped off the dirty side of the surface filter and falls downwards. In order to enable the filter cake to fall off, to equalise the pressure with the dirty space, a bypass gas flow passes from the dirty space through the chamber into the clean space.
Patent DE-3215695-A1 (DE)
Title: Electronic yarn monitor for monitoring the yarn run in textile machines
Inventor: SCHOELLER EUGEN ING GRAD
IPC: B65H63/032
Filed: 1982-04-27
Abstract: The invention relates to an electronic yarn monitor for monitoring the yarn run in textile machines. The yarn monitor is equipped with an electronic sensor which senses the movement of the yarn and the output signal of which is applied by way of a junction cable to an electronic evaluation circuit arranged spatially at a distance from the sensor. The sensor is followed by an impedance converter, at the output of which there is a low-impedance signal which is insensitive to disturbing influences, such as, for example, the mains frequency. Simple, non-shielded junction cables can therefore be used between the sensor and evaluation circuit.

IPC: D06F43/08
Filed: 1982-10-28
Abstract: A cleaning apparatus for the chemical cleaning of articles made of cloth contains a treatment space (3), in which the articles are first washed with a solvent and are subsequently dried and, if appropriate, aired. For this, the treatment space (3) is connected to a solvent circuit and to a hot-air circuit. The former contains a dirt-filter device (8), and contained in the latter is an air cooler (17) having a condensate separator as well as an air heater (18) following this. For drying the dirt in the filter device (8), there branches off from the hot-air circuit after the air heater (18) a first air line (25), by way of which some of the hot-air stream flows into the filter device during the drying of the articles. On the outlet side, a second air line leads back from the filter device (8) to the hot-air circuit. If appropriate, circulating air can be made to flow into the filter device (8) after the hot-air stream and is returned to the treatment space (3) after the filter device. A blower (43) is inserted in the bypass formed by the two air lines, in order to increase the air throughput through the filter device. <IMAGE>

Title: Walking system for conveying at floor level, having fixed and movable devices, their design and their interaction
Inventor: EGGENMUELLER ALFRED DR ING
IPC: B65G25/02
Filed: 1983-08-23
Abstract: The invention relates to the design of walking mechanisms and their use as fixed devices and as moving vehicles. Here, solutions are proposed which permit a space-saving design, principally in terms of height, so that the constructional height is not substantially greater than the height of the walking boards 2, 3, 4 and 5 which is necessary as a result of their loading. The design is effected essentially by means of two troughs 6 and 7 in which in each case one pair of walking boards are mounted. The gear systems 13 and 14 and the engine 16 are flanged onto one of the troughs 6. The two troughs are connected to one another with transverse struts 15. Proposals for the operation and interlinking of walking devices in walking systems are given for their use when connected one behind the other. In this case, the problems of the transition and of the optional connection of two walking systems are solved. <IMAGE>
