Patent DE-3937148-A1 (DE)
Inventor: MUELLER WOLFGANG HANS-GEORG DR
IPC: G01R33/385
Filed: 1989-11-08
Abstract: The invention concerns a system for the generation of magnetic gradient fields which intermittently overlap the static magnetic field of a nuclear-spin tomograph. The system has at least one pair of gradient coils which are fed from a mains-powered device, through which current flows in series when in operation and which generate, in a given volume of material under examination, a gradient magnetic field which varies at least approximately in linear fashion with position in one direction. The system is characterized by the fact that each gradient coil (A, B) has a set of windings with at least a first winding zone (S1) and a set of windings with at least a second winding zone (S2) which have separate connections (16, 17; 18, 19), such that the winding zones can be easily connected to each other, and disconnected in a different way. This enables the user to alter the properties of the gradient system.

IPC: G01D5/34
Filed: 1989-11-27
Abstract: In such a position measuring instrument for measuring the relative position of two objects, a division carrier (M1) connected to one object exhibits an incremental division (T1) and several identical reference marks (R1a, R1b, R1c) permanently allocated to the division (T1). The strips of the reference marks (R1a, R1b,R1c) are formed by the strips of the incremental division (T1). To distinguish between them, the strips of the reference marks (R1a, R1b, R1c) have a cross- polarising line pattern and the strips of the incremental division (T1) not used for the reference marks (R1a, R1b, R1c) have a longitudinally polarising line pattern. The scanning divisions (AT1a, AT1b) of a scanning plate (AP1) scan both the cross-polarising strips of the reference marks (R1a, R1b, R1c) and the longitudinally polarising strips of the incremental division (T1) for generating measurement values. The reference mark scanning division (RAT1) of the scanning plate (AP1), the cross-polarising strips of which are identical to the cross-polarising strips of the reference marks (R1a, R1b, R1c), only generate a reference signal (RS1) during the scanning of the reference marks (R1a, R1b, R1c). <IMAGE>

Title: Ceramic surface treatment - by applying flame fuelled by combustion gas and oxygen@ to roughen surface structure during mfr.
Inventor: VOCKE PETER DR ING
IPC: C04B41/00
Filed: 1990-11-20
Abstract: The surface design of ceramic workpieces is achieved, during the mfg. process by subjecting it to a flame which burns a mixture of fuel gas and oxygen or a gas containing oxygen. After the workpiece has been fired, it is heated to a temp. above 500 deg.C before the surface is treated with the flame. The burner, for the surface flame treatment, is located at the conveyor rails for the workpieces, where they travel through the whole mfg. process. The flame, fueled by an oxy-acetylene mixture, according to the proportions, delivers a flame heat of 2500-3200 deg.C and the burner head is moved over the ceramic workpiece at a gap of about 5mm from its surface, equally over the whole surface area, to give it a roughened and non-slip surface. USE/ADVANTAGE - The process is for mfg. tiles and plate material for floors and walls, with a structured surface roughness. The surface treatment gives the ceramic material a new surface character, without affecting the moulding or embossing processes on the ceramic mass.
