Abstract: The three-sided dumper truck 5 is provided with a left-hand tipping cylinder 7 in the direction of travel 21 and a right-hand tipping cylinder 8 each of which is single-acting, the tipping taking place simultaneously by means of both tipping cylinders. In addition, a control device 21 for acting on the two tipping cylinders differently during the tipping of the loading surface 6, as a function of the distortion of the loading surface 6, about a rear tipping axis which runs transversely and horizontally with respect to the direction of travel 22. This control device 21 consists of a torsion shaft 24 with a transverse bar 27 and of electrical switches 28, 29 which are controlled by the latter. In the region of the rear tipping axis, the torsion shaft 24 is secured with its rear end and is always directed forwards in the direction of travel underneath the loading surface 6 and has at its other end a rigidly fixed transverse bar 27. In the region of each end of the transverse bar 27 there is in each case an electric switch which can be actuated by the respective end of the transverse bar, the two electric switches being secured in the front region of the loading surface 6 (Figure 2). <IMAGE>

Patent DE-3615600-A1 (DE)
Title: Agricultural tractor
Inventor: LELY CORNELIS VAN DER
IPC: B62D49/06
Filed: 1986-05-09
Abstract: The tractor has laterally adjustable wheels which can be set in such a way that the rear wheels run selectively in or outside the tracks of the front wheels. As a result, for example during seedbed preparation, an excessive compacting of the soil in the wheel tracks can be avoided, and although there are four wheel tracks for each distance of travel, these nevertheless have a smaller depth, in comparison with front and rear wheels aligned with one another. Moreover, in the offset setting of the wheels, asymmetric loads on the tractor and transverse forces originating from the ground, which otherwise occur when a machine is mounted on the tractor asymmetrically to its longitudinal axis, are eliminated.

Title: Device for controlling the temperature of a clean-air current
Inventor: KREYENBERG KARL HEINZ
IPC: A61G13/00
Filed: 1986-11-20
Abstract: The device for controlling the temperature of a clean-air current adjusts the temperature of the clean air largely without wear, quietly, and using little energy. It has at least one fan head from whose air outlet the current of clean air emerges and blows across a clean field. The temperature of the current of clean air is intended to differ from the ambient air temperature. A heat exchanger that controls the temperature of the clean-air current takes the form of one or more Peltier elements. Several Peltier elements, forming the heat exchanger, are connected together in series. The Peltier elements connected in series are preferably cascaded. The Peltier elements have both heat-absorbing and heat-emitting junctions. The junctions are mounted in cooling or heating plates.

Title: Method of applying conductor tracks to cutting attachments made of mechanically resistant materials
Inventor: KOENIG UDO DIPL PHYS DR RER NA
IPC: H05K3/04
Filed: 1987-01-10
Abstract: In a method of applying conductor tracks to cutting attachments made of mechanically resistant materials which comprises embedding a layer made of nonconducting mechanically resistant materials which has been applied to the parent body, parts of a surface layer made of electrically nonconducting material which are not to be provided with conductor tracks are masked in a first step with a substance which prevents the material to be applied in a second step as the conductor track from bonding to the material of the parent body. In a further step the material layer on this substance is then removed by abrasion. Boron nitride powder has proved particularly suitable as a masking layer.

Patent DE-3712761-A1 (DE)
Title: Winding machine
Inventor: SCHIPPERS HEINZ DR ING
IPC: B65H54/28
Filed: 1987-04-15
Abstract: In traversing devices with reversing-thread traversing, there is the problem, at high thread speeds, that the thread guide (8) guided in the reversing thread has to reverse its direction of movement at the stroke reversal points with very pronounced deceleration and acceleration. For this reason, it is proposed that the reversing thread (7) extend only over a part stroke in the middle traversing region. Flyer-traversing units (11) and (12) are provided for the end regions, with at least one pair of flyers (13, 14) rotating in opposition. Each flyer-traversing unit (12, 13) sweeps over a stroke-end distance (16). The total-stroke distance is an integral multiple of the stroke-end distance. <IMAGE>

Title: Arrangement of suction rings in sheet brakes of sheet deliverers
Inventor: ZIMMERMANN HANS
IPC: B65H29/24
Filed: 1987-04-21
Abstract: The invention relates to an arrangement of suction rings in sheet brakes of sheet deliverers in printing machines. The sheet brakes are arranged upstream of the delivery stack and consist of a suction-ring traverse, a squared shaft as drive, suction rings which are axially displaceable thereon and spaced from one another and a suction-air feed. The object of the invention is to provide an arrangement of suction rings in sheet brakes which makes possible an axial adjustment of the suction rings and ensures, in any setting, that the suction ring bears against the suction-ring bearing with a defined force. This is achieved according to the invention in that a torque-transmission element engaging in a rotationally fixed manner in the suction ring is provided on the drive shaft. The torque-transmission element is assigned, with spring loading, to a ball race rigidly connected to the suction-ring bearing and the suction ring is assigned, with spring loading, to a check ring rigidly connected to the suction-ring bearing. The torque-transmission element is arranged displaceably on the drive shaft. <IMAGE>

Patent DE-3718791-A1 (DE)
Title: Process and apparatus for distilling liquids
Inventor: PLOECHINGER HEINZ
IPC: B01D5/00
Filed: 1987-06-04
Abstract: The start of evaporation at the condenser (3) is determined by a first sensor (5). Thereupon, the pressure decrease is continued with the vacuum pump (4) until the presence of vapour is also established at a second sensor (6). Thereupon the system pressure is kept constant in such a manner that the condensation front in the condenser (3) always remains in the desired range. This permits an optimisation of the distillation process and an exploitation of the maximum cooling performance independently of the cooling medium temperature and independently of the absolute pressure and the absolute temperature. <IMAGE>
