Abstract: For carrying out a self-test on a dual-port memory (CSP) which is arranged on a chip with other units and contains operating data for the operation of the units, the memory (SP) is designed in such a way that the self-test can be carried out without loss of operating data stored in the memory and without these operating data having to be read out from the memory. For this purpose, the dual-port memory is constructed as two single-port memory modules (SPE1, SPE2), which in operation have identical contents, but in the case of a test can be differently selected and can be tested separately from each other. The memory module which is not being tested then holds the operating data, which after testing the other memory module are written to it. The memory also includes a signature register (S-RG) for forming a signature from the test response signals emitted from the memory modules and a comparator circuit (VGL) with the set signature. <IMAGE>

Abstract: This invention relates to an abrasive granule, and, in particular, one which comprises an agglomerate having individual abrasive grains coated on the periphery thereof. 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. To overcome this problem of waste, many attempts have been made to distribute the abrasive grains on the backing in such a manner so that a higher percentage of abrasive grains can be utilized, thus leading to extended life of the abrasive product. This invention provides an erodable abrasive granule comprising a plurality of first abrasive grains bonded together by a first binder to form an erodable base agglomerate and at least a partial coating of second abrasive grains bonded to the periphery of the base agglomerate by means of a second binder. These abrasive granules can be incorporated into a wide variety of abrasive articles such as grinding wheels, coated abrasives, and non-woven abrasives. The addition of these second abrasive grains dramatically increases the grinding performance over the base agglomerate by itself.

Abstract: A coin escrow includes a storage chamber (2) having a side wall (3) and a base (5). In use, coins are stacked edge to edge in the storage chamber (2). The escrow includes one or more projections (10) which are moveable in the chamber (2) in the sideways direction. The projections (10) are biased towards the side wall (3) and engage one face of a coin stored in the storage chamber (2). Wide and consequently heavier coins displace the projections as they run along the base (5) of the storage chamber (2) but narrow and consequently lighter coins do not displace the projections (10). The projections hence prevent narrow coins from overlapping one another in the sideways direction in the storage chamber (2). 
     In one example, the projections (10) are provided by balls projecting through a side wall opposing the one side wall (3). The balls are gravity-biased.

Abstract: The angioplasty light guide catheter has a dilatation balloon (1) which is to be introduced into the vessel to be treated. The inside of the balloon is connected via a shaft to a suction and forcing pump and can therefore be regulated precisely in diameter. Light guides (6) extend over the entire length of the shaft and are coupled to a laser device via a connection piece at the proximal end of the catheter. At the distal end the light guides are embedded in the wall of the dilatation balloon (1). For stenosis ablation using laser light energy, the outlet points of the light guides can be moved radially outwards and inwards by changing the pressure in the dilatation balloon. The distance of the outlet points (6a) from the centre line of the balloon is thus a function of the pressure of the balloon fluid. This distance can thus be altered and controlled in a simple manner.
