Patent DE-4110903-A1 (DE)
Inventor: LANGER HANS J DR
IPC: B29C33/60
Filed: 1991-04-04
Abstract: In a device or process for producing an object by the successive securing of superimposed layers in a bath of fluid or powdered material by the action of electromagnetic radiation, there arises the problem of how to adjust the layer thickness of the material quickly and accurately before securing. To solve this problem it is proposed to adjust the distance between a base plate or the layer already secured and the top of the bath in such a way that it is greater than the thickness of the layer to be secured, to form a region at the point of action of the radiation in the bath with a surface reduced in suitable proportion to the thickness of the layer to be secured and to shift the region together with the position of the effect of the radiation to secure the object along the surface of the bath.

Patent DE-4137485-A1 (DE)
Inventor: FUNKE THOMAS
IPC: H01H13/18
Filed: 1991-11-14
Abstract: In order to obtain a largely wear-free, manually actuated dirt-insensitive switching device, useful in particular in areas where there is a danger of explosion, a system is disclosed using an inductive proximity switch (12) that is adjustably arranged in a housing (1) and that cooperates with a metallic plate secured at one end of a rod (13). Said rod (12) carries a button (8) at its end opposite to the plate (19). The button (8) is elastically retained in one of its extreme positions by means of a spring element (15) and is designed for sensing operation, so that when it is actuated the plate (19) is brought near to the proximity sensor (12) and causes its switching state to change. The proximity sensor (12) is a commercially available, intrinsically safe standard component. This switching device, which is largely made of plastic, is therefore particularly useful in areas where there is a danger of explosion.
