Diese zweite Kratzkante (26) kommt beim Durchgang des Kratzers durch das geschlossene Untertrum zur Wirkung. Der erfindungsgemäße Kratzer wird außerdem vorzugsweise so profiliert, dass er bei gleichem Gewicht dasselbe Widerstandsmoment hat wie die bekannten Kratzer.
Patent DE-3151481-A1 (DE)
Title: Agricultural machine
Inventor: JAKOBI WILHELM
IPC: A01D34/66
Filed: 1981-12-24
Abstract: The agricultural machine shown has two supporting beams (1 and 2) which are arranged next to one another so as to be aligned transversely relative to the direction of travel and which are equipped with downwardly directed mowing drums (4, 4') supported on the ground via supporting shells (5) and having mowing cutters (13, 13') and, for adapting the machine to the ground, are connected to one another so as to be vertically pivotable within limits. The pivoting connection has two sliding joints (10, 15 and 11, 16) provided on adjacent supporting-beam ends (9, 14) and movable about a common ideal mid-axis (12), the mid-axis (12) extending in the direction of travel centrally between the adjacent supporting-beam ends (9 and 14) approximately level with the mowing cutters (13, 13'). By means of the pivoting connection according to the invention, when there is unevenness of the ground, the supporting beams (1 and 2) can pivot vertically relative to one another, without gaps or excessive cutter overlaps occurring in the working region between the two adjacent mowing drums (4 and 4'). Uniform mowing work is achieved thereby, and the absence of a physical pivot axle in the region of the stream of mown material guarantees uninterrupted mowing work. <IMAGE>

Title: Method for transformation of co-ordinates
Inventor: GIELEN HARALD DIPL ING
IPC: G06F7/548
Filed: 1982-02-04
Abstract: The invention relates to a method for transformation of UTM co-ordinates from a first grid zone into a second adjoining grid zone. This method can be used, in particular, in determining the position of vehicles by means of navigation systems. If the vehicle reaches the edge of a grid zone and if the position is to be specified thereafter with the co-ordinates of the adjoining grid zone, the angle of convergence at the zone boundary is calculated, after determination of the zone width ZB1 from a table, and this value is used for forming an approximate value for the north co-ordinate of the second grid zone NZ2 in accordance with the relation  NZZ = N1-2(E1-EZB1).sin gamma in which N1 designates the north co-ordinate of the first zone and E1 designates the east co-ordinates in the first zone. The east co-ordinate E2 in the second zone is calculated in accordance with the relation  E2 = E1-2(ZB1-500 km) To obtain even greater accuracy, a further calculation and an error correction calculation can be carried out using the first calculated values. <IMAGE>

Title: Clutch device between drive device and screw of the plastication unit of an injection moulding machine
Inventor: KREBSER RUDOLF
IPC: B29C45/50
Filed: 1982-08-05
Abstract: The output piston (10) of the drive device (6) is provided with a clutch housing (11), in which a clutch piston (16) which is spring-loaded in the direction of clutch engagement and can be loaded by a pressure medium in the direction of clutch disengagement is guided. The clutch piston (16) is connected by means of a tappet (18) to a tensioning cage (19). On account of the spring loading of the clutch piston (16) the tensioning cage (19), which is disposed in the radial direction between the clutch housing (11) and a head part (20a) of the screw shaft (21), is deformed in such a manner that it connects the clutch housing (11) and the screw shaft (21) by frictional connection in such a manner that both axial forces and torques can be transmitted from the drive device (6) to the screw (2). By applying pressure medium to the clutch piston (16) in opposition to the spring effect the tensioning cage relaxes and the frictional connection is released, so that the plastication unit (1) can be removed. The clutch device is especially suitable for fully automatic replacement of the plastication unit (1). <IMAGE>

Title: Method for bringing about ground contact by aircraft quickly and automatically
Inventor: RAAB PETER KLAUS DIPL ING
IPC: B64C25/42
Filed: 1982-08-21
Abstract: A method is proposed for bringing about ground contact of all the undercarriage parts, nose/tail wheel, and main undercarriage of aircraft quickly and automatically. In this case, the method relates to those aircraft which do not carry out a three-point landing. The intention of the method is to bring about the fastest possible use of the brakes and/or braking aids of the aircraft in order that emergency braking and short landings can be carried out in the shortest achievable landing runs. To this end, it is provided that the aircraft is aligned in a controlled manner to the undercarriage part which is not yet on the ground, but to this end, in sensor terms, the flight status data, pitch and yaw movement of the aircraft and the relative position of the undercarriage parts with respect to the ground are determined, and that the undercarriage brake and other braking aids are operated automatically, with the steering and anti-lock braking systems being switched on, in order that, because of the friction forces, the undercarriage part which is not yet on the ground is placed on the ground with the greatest possible load taking into account the specified strength limits. <IMAGE>

Title: Bathtub for delivering electroplating baths
Inventor: KRUST OTTOKAR
IPC: A61N1/44
Filed: 1982-09-01
Abstract: The bathtub has electrode plates which have a keyhole-like attachment opening for attachment near to the inside of the bathtub. The counter-piece attached to the tub for connection is a formed by a bolt in a mushroom-like shape, the head portion of which bolt can be passed through the somewhat larger plug opening of the attachment opening. This head portion reaches, by lateral displacement, the region of a slot with reduced internal width, so that the plate is then held. The electrode plate is then supported by its outer edge, onto which an edge profile is affixed, on the tub and the electrode plate springs in somewhat elastically in the bolt region due to the internal spacing of the head portion provided. The plate is on the one hand sufficiently fastened by this prestressing, and on the other hand can still be displaced into different positions, corresponding to the course of the slot.

Title: Holding device for a plurality of semiconductor wafers having identical dimensions
Inventor: WASSILL JOACHIM
IPC: H01L21/673
Filed: 1982-10-01
Abstract: As is known, so-called carrying trays on which a fairly large number of mutually identical semiconductor wafers are arranged in each case and which are then subjected to a common manufacturing process on the tray are used in the production of semiconductor devices. Since, however, trays made of different material are necessary for the various manufacturing processes carried out in succession, there is always the problem of transferring the semiconductor wafers held on a first tray to a second tray. The present invention now provides a mutually matched geometrical design of the two trays which is such that the semiconductor wafers on the first tray can be transferred to the second tray simultaneously without slewing.

Title: Method and device for controlling the brake pressure in a motor vehicle
Inventor: STUMPE WERNER
IPC: B60T8/26
Filed: 1983-04-12
Abstract: Method and device for controlling the brake pressure fed to wheel brake cylinders by a service brake valve in a motor vehicle, different response thresholds in the braking of the individual wheels or individual axles being equalled out in that the initial pressure level is switched from front to rear axle and vice versa. In the case of braking processes at low brake pressure this results in a controlled response of only certain wheel brake cylinders, preferably only of the front axle or only of the rear axle in a motor vehicle. In this way a uniform wear is obtained. For selective triggering a change-over device with adjustment valves triggered by the change-over device and arranged in the brake pressure lines to the front and rear axle is provided. The adjustment valves are designed as relief valves, so that in normal braking sequences all brakes can be used for deceleration. <IMAGE>
