Patent DE-3402694-A1 (DE)
Title: Method and device for movably supporting a load on a level surface
Inventor: KIPFER HUGO
IPC: B65G7/02
Filed: 1984-01-26
Abstract: The load is supported on a soft and/or sensitive floor (1), e.g. a workshop floor, by means of a device which has a runner (4) on its underside. A section of a belt (5) which can be moved in relation to the runner (4) in the longitudinal direction of the belt is situated between the level underside of the runner (4) and the floor (1). When the load is displaced, the runner (4) slides on the said belt section, which remains stationary in relation to the floor (1). The floor (1) is therefore not subject to wear. The weight to be borne by the device is evenly distributed over the entire surface of the level underside of the runner (4). The surface load on the floor (1) is kept small by these means. <IMAGE>

Title: Screeding bar
Inventor: CARL HEINZ ING GRAD
IPC: E04G11/36
Filed: 1984-02-14
Abstract: A description is given of a screeding bar for use when producing concreted surfaces, which has a three-dimensional grid body and a screeding surface running along its upper edge, and which is cost-effective and uncomplicated to handle. For this purpose, the screeding surface is formed by the surface of a concrete screed which encloses the upper edge of the grid body and leaves the lower edge of the grid body free. This screeding bar can be simply designed for various purposes. In one preferred exemplary embodiment, for example, the screeding bar contains a shuttering, the upper edge of which is likewise embedded in the concrete screed. The shuttering rests on the grid body on a side directed away from the concrete and comprises a grid strip, on both sides of which a plastic film has been shrunk on. In another exemplary embodiment, additional reinforcements are embedded in the concrete screed which, in the transporting state, bear against the grid body and, before casting, can be bent up in the concrete. Furthermore, specific application possibilities are described, for example for producing an expansion joint or as shuttering for casting foundation beams.

Patent DE-3442499-A1 (DE)
Title: Rotary-chamber vibration grinding mill
Inventor: GOCK EBERHARD
IPC: B02C17/14
Filed: 1984-11-22
Abstract: The invention relates to a rotary-chamber vibration grinding mill whose vibrations are circular or form similar paths and whose milling pipes are equipped, parallel to their axes, with one or more freely movable chamber wheels which carry out movements which are synchronous with the rotating filling of the mill. By means of a diameter of the chamber wheels which is substantially smaller than the difference between the inner diameter of the milling space and the maximum customary vibration amplitude of 12 mm in vibration grinding mills, changing of the milling bodies in the vibration plane and over the entire length of the milling space is ensured. The technical progress which this constructional measure constitutes with regard to conventional vibration grinding mills lies in the fact that a compensation of concentration of the material for milling is obtained over the entire volume of the mill, that local wear zones on the armouring of the mill are eliminated and thus the service life is increased, that weakly stressed zones in the centre of the milling space are eliminated, and that a narrow energy distribution spectrum is obtained so that classifying measures are dispensed with, and also lies in the resulting condition for the use of previously unachievable mill sizes with milling-pipe diameters greater than 700 mm, in the manifold increase of the throughput with the same comminution objective and the same milling volume, and in the significantly reduced expenditure of energy per tonne of material for milling.
