A stationary pressure clamp (20) is provided above a stacking table plate (2) in the vehicle advance position, and the pressure board (23) of the pressure clamp (20) can be swung out sideways onto the front end of the transport vehicle to take hold of the piece goods resting thereupon, retain them during the subsequent return movement of the transport vehicle and lay them on the stacking table plate and/or the already existing pile. <IMAGE>
Patent DE-3303773-A1 (DE)
Title: Connection of the ends of conveyor belts
Inventor: HAMMEL KLAUS
IPC: F16G3/10
Filed: 1983-02-04
Abstract: For making the endless connections in conveyor belts having two fabric reinforcing inserts, DIN 22121 is legally binding. To satisfy the demands, increased with the use of especially low-stretch two-ply belts, as regards the bending behaviour of the connection points, along with a high tensile strength and a uniform belt thickness, the invention provides a novel overlap design of the fabric plies assigned to the two belt ends, the intermediate rubber being completely removed in the connection region and the fabric ends butting flush against one another being laid onto one another in the middle of the belt. The butt joints offset relative to one another in the longitudinal direction are advantageously covered with additional stretchable fabric strips. The invention prevents the occurrence of stress peaks, otherwise leading to premature detachment, in the respective outer fabric ply when the connection points run round the driving and deflecting pulleys of the conveyor installations, and therefore results in substantially longer service lives.

Patent DE-3308707-A1 (DE)
Title: Collum washer
Inventor: IMHOF RAINER DR
IPC: B03B5/06
Filed: 1983-03-11
Abstract: Collum washers with mechanical drives are used for the preparation of minerals, especially for very fine-grained minerals. Due to the transverse forces acting on the dead plate during operation of the Collum washer and due to the relatively small stroke length of the dead plate, a sharp separation, especially of fine-grained minerals of less than 100  mu , is impossible to achieve in many cases. According to the invention, a sufficiently sharp separation is, however, obtained for mixtures of minerals with a grain size even below 100  mu , by the table plate (1) being slidingly guided on several supports (2). <IMAGE>

Title: Rail wheel with rubber suspension
Inventor: RITTINGHAUS ROLF DIPL ING
IPC: B60B17/00
Filed: 1983-04-28
Abstract: The rail wheel with rubber suspension consists of the wheel tyre, the rubber elements, two rim rings and a wheel disc element. The rim rings can be pushed over the wheel disc element from one end side and one rim ring is pushed on until it stops against one end side of the wheel disc element and is fixed. The other rim ring is slotted and has, in the direction of the wheel hub, a circumferential stop with bores for tensioning screws. When changing the wheel tyre and/or the wheel element, the assembly consisting of wheel tyre, rubber elements and the rim ring having the circumferential stop is pulled off from the wheel disc element. The overhauled assembly is subsequently remounted. In this process, the wheel disc element remains on the axle. This constructional design permits rail wheels with rubber suspension, a wheel tyre, rubber elements and a wheel disc to be converted to rail wheels with rubber suspension having these features. Wheel tyres with the original dimensions are used so that retrofitting is readily possible.

Title: Method for regulating the volumetric flow rate of dosing pumps
Inventor: NEUMANN BERND
IPC: F04B49/12
Filed: 1983-10-28
Abstract: The object of the invention is to increase substantially the dosing accuracy of dosing pumps in continuous operation with constant rotational speed of the drive and using the stroke length as the manipulator variable. This is to be achieved by providing a method which eliminates the effect of fluctuations in the rotational speed of the drive, which are caused by the grid and the load, on dosing accuracy. The object is achieved by using the stroke length and the stroke time to calculate the flow rate, and by compensating for the flow rate changes at constant rotational drive speed by means of adjusting the stroke length.

Patent DE-3401802-A1 (DE)
Title: Hot mangle
Inventor: GEIGER FRIEDRICH DIPL ING
IPC: D06F65/08
Filed: 1984-01-19
Abstract: The invention, with a view to generating a uniform pressing pressure in conjunction with a considerable saving of weight and energy, is concerned with a special mounting and driving technique for the mangle roller (2) of hot mangles. Whereas, in the state of the art, the mangle roller (2) is driven via a toothed-belt drive located on the end face and extending along a lever (4) carrying the mangle roller (2), the invention provides for incorporating this lever (4) into a four-bar chain, the web (16) of which is formed by a vertical lever leg on which the lever (4) is mounted at (5). The link (17) located opposite the web (16) is formed by a gear case (18) having a lever part (19) connected rigidly to it. The gear case (18) is pivotable about the axis (3) of the mangle roller. A supporting lever (21) acting as a lower rocker is located opposite the lever (4). The toothed-belt drive (11, 22, 23) is guided along the supporting lever (21) as far as an output wheel which is located at a distance from the axis (3) of the mangle roller and from which the mangle roller (2) is driven via a gear located inside the case (18). The rotational torque occurring as a result of friction during the drive of the mangle roller (2) is introduced approximately horizontally into the rockers (20, 21) via the link (17), with the result that a negative influence of the drive on the pressing pressure is eliminated. <IMAGE>
