Abstract: This invention relates to erodable agglomerates containing abrasive grains and to abrasive products containing these agglomerates. 
<??>Conventional coated abrasives typically consist of a single layer of abrasive grain adhered to a backing. It has been found that only up to about 15% of the grains in the layer are actually utilized in removing any of the workpiece. It follows then that about 85% of the grains in the layer are wasted. Furthermore, the backing, one of the more expensive components of the coated abrasive, must also be disposed of before the end of its useful life. 
<??>This invention provides erodable agglomerates containing individual abrasive grains, a binder and matrix material selected from the group consisting of pulp suitable for making paper and derivatives thereof, wood flour, and vermiculite. The agglomerates are useful for coated abrasives and bonded abrasives. Abrasive products containing the agglomerates provide higher stock removal than abrasive products bearing a single layer of abrasive grains, since the erodable character of the agglomerates allows the sloughing off of spent individual abrasive grains during abrading operations and the exposing of new abrasive grains to the workpiece. The invention also provides a method of preparing the agglomerates of this invention.

Date Dec. 17, 1987.In a method and a device for the widespread fine-bubble aeration of liquids, resilient, perforated membranes, which are preferably in the form of aeration hoses, are arranged in a liquid receptacle and are maintained horizontal by means of holding and guiding devices and are stretched, relative to their rest states, preferably by means of tensioning devices. Because of the stretching, the passage of the gas is improved and a uniform, finely dispersed gas bubble formation is produced. For clearing the perforated membranes of blockages of the perforations, the streteched state of the membranes is briefly released and subsequently again reproduced. For strong impurities, the gas supply is interrupted, the membranes are exhausted of gas and water, the stretched state is subsequently released and, after a predetermined time, gas is again fed into the perforated membranes and then the stretched state is reproduced.

Abstract: The invention relates to a catch device against undesired rolling of a roller door. A first worm wheel (2), which is connected to the roller door shaft (4) in a rotationally fixed manner, and a second worm wheel (5), which is mounted rotationally movably with respect to the first worm wheel (2) and the roller door shaft (4), mesh with the driving worm (1). The second worm wheel bears driver elements (7), which displace the blocking bodies (8) within a frictional locking mechanism (6-10) between the supporting surfaces (9, 10). During normal operation, the blocking bodies (8) are located approximately in the region of the centre of the supporting surface (9), so that the roller door shaft (4) runs freely within the stop (6) fixed to the housing. In the event of disturbance, for example wear of the teeth of the first worm wheel (2), a rotation of the two worm wheels (2, 5) relative to each other leads to a positional change of the driver elements (7) and thus of the blocking bodies (8) so that the roller door shaft (4) is blocked by means of the blocking bodies (8) directly against the stop (6) which is fixed to the housing, without the blocking force having to be transferred from the second worm wheel (5).
