Title: Method for the defined abrasive surface-treatment of bodies
Inventor: GAWORZEWSKI PETER
IPC: B24B7/16
Filed: 1993-05-19
Abstract: The invention relates to an apparatus for the defined abrasive surface-treatment of bodies, in particular for bodies consisting of specimen materials, for material-analytical tests to be carried out subsequently, with the aim of producing ground surfaces, in particular angular (bevelled) ground surfaces, free from curvature. The object of the invention is to guarantee in a very simple manner that at the very beginning of the grinding process, at the moment of contact of the test specimen, which is to be worked abrasively, with the grinding tool, only one degree of freedom of translation for the material which is to be worked abrasively is allowed. This is acheived in that the body which is to be worked abrasively is connected via a shaped piece which embeds it to a body slidingly fitted in a mounting, and thus only the mounting can be pressed onto the tool immediately at the beginning of the grinding process, with the result that parallelism between end face of the mounting, surface of the test specimen and surface of the tool is provided at the very beginning of the abrasive working process of the test specimen. <IMAGE>

Patent DE-4412630-A1 (DE)
Title: Bagatelle game
Inventor: LAWLOR PATRICK M
IPC: A63F7/32
Filed: 1994-04-13
Abstract: A ball of non-ferromagnetic material, such as for example plastic or ceramic, is included with ferromagnetic balls. When the microprocessor of the game detects that the non-ferromagnetic ball is in play, the game can be changed by point scores and scoring sequences being changed, different elements of the playing area being activated, etc. In order to signal to the microprocessor that the non-ferromagnetic ball is in play, an eddy current sensor (12) is arranged in the movement path (2) of the bagatelle balls. The eddy current sensor generates a signal when its magnetic field is changed by the presence of a magnetic material. As a result of the ball running past the eddy current sensor at a predetermined time, and recording of the signals of the eddy current sensor, the microprocessor can thus detect whether the ball is ferromagnetic or non-ferromagnetic, and can change the game accordingly. The use of a non-ferromagnetic ball and of a sensor allows ferromagnetic and non-ferromagnetic balls to be mixed in a multiple ball game, special play elements being imposed when the non-ferromagnetic ball is in play. <IMAGE>
