Title: Method of use for a fertiliser broadcaster which can be mounted onto a farm tractor
Inventor: DREYER HEINZ DIPL ING
IPC: A01C17/00
Filed: 1988-03-24
Abstract: Method of use for a fertiliser broadcaster which can be mounted onto a farm tractor and has at least two centrifugal discs which are driven in a rotating manner and on which throwing blades are secured, which centrifugal discs can be driven by the power take-off shaft of the farm tractor at normal speed and at a clearly reduced speed relative to the normal speed of the power take-off shaft, measures being provided for compensating for the disadvantageous changes in the scattering pattern resulting from the change in speed. In order to provide a method of use in which a uniform scattering pattern is maintained but the centrifugal discs can be driven at a clearly reduced speed in order, in this manner, to be able to use large farm tractors in a manner which saves fuel, and to provide a corresponding fertiliser broadcaster for carrying out the method of use, it is provided that the changes in the scattering pattern which result from the change in speed of the speed of the centrifugal discs because of the reduction in the speed of the power take-off shaft, are compensated for by changing the angular position of the throwing blades (14, 14', 15, 15') in the plane of the discs so that a uniform distribution of fertiliser is produced and maintained (Fig. 3). <IMAGE>

Title: Loading shovel, for example for a selective-cut heading machine
Inventor: WAGNER HUBERT DIPL ING
IPC: E02F3/40
Filed: 1988-08-31
Abstract: Loading shovels are very often arranged in a vertically adjustable manner on the machine frame of a selective-cut heading machine and lie with their front loading edge, facing the heading face, on the roadway floor. Consequently, excavated material cannot be prevented from passing laterally, from the roadway sides, under the loading shovel and thus into the area of the machine travel way. During its driving work, the selective-cut heading machine runs with its crawler chains onto this excavated material, climbs and thus leaves its predetermined working level. The climbing of the selective-cut heading machine is to be prevented by means of the loading shovel. It is proposed to fit a deflector plate (13) on both sides of the loading shovel (7). The deflector plate (13) extends over the length of the shovel side wall and its height is dimensioned in such a way that it laterally covers the free space (15) located under the loading shovel (7). In addition, it is mounted in a vertically movable manner on the shovel side wall (12) in such a way that it rests under its own weight over its entire length on the roadway floor (10). <IMAGE>

Title: Device for the removal of soil samples with a soil auger from three soil depths for soil investigations
Inventor: BEHRINGER PAUL DR
IPC: E21B7/02
Filed: 1988-11-18
Abstract: The device, which is mounted on a tractor, has a soil auger which rotates vertically in the manner of a screw into the soil. By interrupting the downward movement while the soil auger rotates further, a cylindrical shaft is produced in the soil, while the earth expelled by the soil auger is pressed firmly between the threads of the soil auger. After raising the soil auger out of the cylindrical shaft, the earth is automatically removed from the threads by means of a wiping-off device and falls separately (0-30 cm, 30-60 cm, 60-90 cm) into the bucket arranged in stages. In the case of a frozen soil surface, at the position at which the soil auger will later be rotated into the soil, the soil is first drilled into with an earth boring drill.

Title: Lifting-roller retractor for vehicle safety belts
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/36
Filed: 1989-03-14
Abstract: A description is given of a so-called second-generation lifting-roller retractor. Its basic feature is a double locking bar 2 in the front upper quarters of the housing leg 7, of which the teeth 6, on both sides, that is to say on the mechanism side and the spring side, produce, with the shaft teeth 3, a synchronised pre-blocking of the shaft 1. Due to this pre-blocking on both sides, the shaft 1 then pivots, on a positively controlled path predetermined by the design, into the load-bearing blocking position. This controlled movement of the shaft 1 is ensured 100% on both sides. Due to the supporting moment by the double locking bar 2 and the shaft 1, in the event of blocking, for a predetermined position of the blocking toothing arrangement, a relatively large belt-extension range Fa to Fz of approximately 120@ is possible. The solution according to the invention permits universal usage of the apparatus with respect to the belt-extension directions and absolutely reliable (i.e. positively controlled) pivoting of the shaft 1 into the blocking position without any negative impairment due to disruptive influences (e.g. oblique belt extension, uncontrolled accelerations. <IMAGE>
