Title: Plough appliance for making a seedbed
Inventor: BUCHTA JOHANNES
IPC: A01B9/00
Filed: 1988-05-21
Abstract: The invention "Plough appliance for making a seedbed" relates to a plough appliance having preferably a plurality of ploughshares, arranged in an upper bearing frame on a vertically adjustable, movable, self-supporting plough structure, in the form of implement rotors which allow the seedbed to be ploughed directly. The plough appliance is drawn by a traction machine, the ploughshares being drivable via the power take-off shaft of the latter and bearing shafts. Since this is possible with a lower expenditure of force than in ploughshares mounted fixedly in terms of rotation, the dead weight and pulling force of the traction machine can be selected lower. The ploughshares are arranged with their bearing shaft respectively between the front and the rear bearing arm in a manner offset laterally and in succession downwards relative to the rolling plane. The ploughshares jointly rotatable in the same direction to the right and left have the form of rotationally symmetrical rotor housings with a front circular cutter wing and a central shaft stub, from which ploughshare blades respectively extend radially outwards and in the longitudinal direction. The bearing shafts of the ploughshares of equal size are oriented in a common horizontal plane parallel to the rolling plane of the plough appliance.

Title: Device for the neatly arranged retention and invalidation of order slips in restaurants
Inventor: GEISSLER HUBERT
IPC: A47G1/21
Filed: 1988-10-21
Abstract: A device for the neatly arranged retention and invalidation of order slips in restaurants consists of a small plastic injection-moulded part (10, 14) which is open at the bottom, has an insertion slot (26) for the order slip and a pivoting detent (16) which is provided with a spike (20) which, in its holding position, penetrates through the insertion slot (26). When an order slip is pushed into the insertion slot (26), the pivoting detent (16) pivots upwards until the spike (20) gets onto the front of the order slip. The order slip can then be pushed up to the upper boundary edge of the insertion slot (26), while the spike (20) slides along the front of the order slip. The order slip cannot drop out of the insertion slot (26), since it is prevented from doing so by the steep-angled spike (20). When the order slip is pulled downwards, the spike (20) penetrates into the slip and tears it. The order slip is thus invalidated. <IMAGE>

Title: Hydrostatic/mechanical power-shift transmission with a continuously variable effect and with toothed selector clutches for shifts proprietary to gear changes and multi-plate clutches for the gear changes
Inventor: JARCHOW FRIEDRICH PROF DR ING
IPC: E02F9/20
Filed: 1988-05-09
Abstract: The transmission consists of a four-shaft planetary gear mechanism, a continuously variable hydrostatic transmission, rear-mounted gear stages and selector clutches. The hydrostatic transmission includes two positive displacement machines. In the planetary mechanism, one shaft forms the input shaft, to which one positive displacement machine is connected. A second shaft of the planetary mechanism is connected to the other positive displacement machine. The third and fourth shafts of the planetary mechanism are coupler shafts, the speeds of which are infinitely variable and which, when rear-mounted stages are connected to the output shaft, form gears, a gear change being associated with a change of the coupler shafts. In the extreme positions of the hydrostatic transmission, selector clutches effect the gear changes at synchronous speeds of rotation, in a manner free from load and without interruption of the tractive effort, and do this without a jerk, i.e. provide a very smooth gear change. In addition, such transmissions have good efficiencies and a wide transmission-ratio adjustment range. They are therefore advantageously suitable for motor vehicles.
