Patent DE-3842379-A1 (DE)
Title: Electromagnetic arrangement in a measuring instrument of explosion-protected design
Inventor: BUSCHMANN HEINZ
IPC: G01D11/24
Filed: 1988-12-16
Abstract: In such electrical instruments, in which all parts are arranged in a protective housing, the interior space must be filled up with a fine-grain filling material. When maintenance work is to be performed, the filling material must then first be removed, but subsequently properly filled in again. If the coil formers are arranged in a relatively small separate chamber meeting the requirements of explosion protection regulations, all other intrinsically safe parts of the measuring instrument can be maintained without problems. The coil formers can be exchanged as an independent explosion-protected component. The maintenance work is facilitated since the cumbersome removal and refilling of the filling material is no longer necessary for the area of the intrinsically safe parts. <IMAGE>

Title: Support for a recording material, and a process for the production thereof
Inventor: GABRIEL GERHARD DIPL ING
IPC: G03F7/09
Filed: 1989-02-28
Abstract: The invention relates to a multilayer support as a base for the lamination of a recording material containing a photocurable polymer layer, where the support has a pigment-containing binder layer on the surface facing towards the photocurable polymer layer. The binder layer is a polyurethane layer, in particular a polyurethane layer applied from aqueous dispersion. The support built up in this way is distinguished by the fact that it enables natural reproduction of the original colour image since it very substantially excludes, in particular, light scattering effects, which result in dot enlargement and thus hue shifts. It can be produced particularly advantageously by applying an aqueous anionic polyurethane dispersion containing from about 6 to 100% by weight of polyurethane (dry substance) per 100 parts by weight of pigment to a support in a conventional manner in a dry application rate from about 3 to 30 g/m<2> and evaporating the aqueous component at elevated temperature.

Patent DE-3916833-A1 (DE)
Inventor: OVERKAMP HANS-THEO BRINGFRIED
IPC: G01N21/67
Filed: 1989-05-19
Abstract: In a procedure for optical spark-emission spectrometry in which a spark plasma of a sample is produced in a spark chamber and is evaluated by spectrum analysis using a spectral apparatus connected, in particular optically, to the spark chamber via a connection space, the connection space and the spark chamber having a protective gas continuously flowing through them during a spark process, a flushing pressure is built up in the gas system upstream of the spark chamber. The sudden release of this flushing pressure, for example, before the start of the subsequent spark process brings about a surge-like flow of the volume of flushing gas released in the spark chamber and, consequently, a complete removal of any burn-up residues or air components from the spark chamber. The gas flow can be interrrupted during the standby time. Equipment for carrying out the procedure comprises a spark chamber with an inlet for the flushing gas which can be sealed gastight by means of a shut-off device which can be opened suddenly. <IMAGE>

Patent DE-3943237-A1 (DE)
Inventor: KUEMMLEE HORST DR
IPC: H02K1/27
Filed: 1989-12-22
Abstract: In permanent-magnet-excited electric machines, the permanent magnets (5) arranged on the stator body (3) of the rotor and spacers (6) of non-magnetic material are held by a facing (7) of sturdy, fibre-reinforced plastic in the air gap (9). When the machine is running, this facing (7) expands to a greater extent than the stator body (3) of the rotor (1), even if it is prestressed, and hence imbalances may arise. According to the invention, in order to keep the arrangement centred, the outer surface (4) of the stator body (3) is divided up over its entire axial length by recesses (11) and the radial elasticity of the stator body (3) is approximately matched to that of the facing (7) with the permanent magnets (5) by special structural measures. The recesses (11) form slots (12) lying radially on the outside and have radially inwardly rounded enlarged sections (14, 15) to prevent stresses. For smaller radii further rounded recesses (16) may also be provided. Such a rotor of a permanent-magnet-excited electric machine is especially suitable for high rotation speeds.

Title: Generating tomographic image using short waves - of same amplitude but of different wavelengths to produce oscillating beats
Inventor: HECKMANN KARL PROF DR MED
IPC: A61B5/053
Filed: 1990-01-03
Abstract: A generator produces e.m. waves of equal amplitude but of different wavelength for electrodes for penetrating the body. Beats arise in the body,i.e. areas in which modulation of the waves attain a max amplitude. By sliding the electrodes and changing the wavelengths in the zone of beat max can be moved over the section to be imaged. A signal can be generated characterising the zone by measuring the intensity of the short wave radiation, which is dependent on the resistance the body exhibits in hte max zone.This electrical resistance is,in turn,dependent upon the nature,density of the tissue. A tomogram is produced fromt he characteristic signal by usual measuring techniques. (4ppDwg.No.1/2) (Printed in week 9132)

Inventor: BRAUN HANS-JOCHEN DR ING
IPC: B29C48/07
Filed: 1990-06-23
Abstract: The invention relates to a process for producing moulded components from cross-linked reaction plastics, especially polyurethane, distinguished by the following process stages: the reaction components of the plastics are mixed in the fluid state; the reaction mixture thus produced is applied in the fluid state to a moving conveyor thus forming a continuous layer, and at least partially cured along a moving section of the conveyor to form a semi-finished product; the semi-finished product is formed without cutting by the effect of a pressure of 150 of 400 bar at a temperature of 120 to 350 DEG C until obtaining the moulding. It is possible with this process, using relatively simple moulding tools, to manufacture large-area and thin-walled mouldings which have constant mechanical properties and outstanding surface quality over their entire length.

Title: Simulation of glass fibre bobbin take-off - uses jet assembly with gas flow to carry material with it
Inventor: HUBRICHT GERHARD DIPL PHYS DR
IPC: B65H51/16
Filed: 1990-11-22
Abstract: To simulate the take-off of glass fibre material (4) from a bobbin (1), and determine the behaviour of fibre optic lightwave guides, a gas (90) is blown in a jet (8). The push tension action on the glass fibre material (4) through the surrounding gas layer (15), carries the material (4) with it. The method gives a simple simulation of the take-off action on glass fibre optic material, at acceleration speeds of 100 m/s2, without damage to the lightwave guide effect. Compressed air is the pref. gas (90). The gas (90) speed at the central section (14) of the jet (8) is less than the sound speed of the gas. The jet (8) has a central section (14) with a dia. (D) of a sufficient size so that the layer of gas (90) at the jet wall (13) in the central zone (14) has no significant effect on the layer of gas (15) round the glass fibre material (4). The dia. (D) of the central (14) section of the jet (8) is exactly double the dia. (d) of the glass fibre material (4). The air stream has to generate sufficient force to overcome the take-off resistance of the glass fibre (such as 5-10 cN) and to accelerate a given material length at, say, 10 g, to a final speed of 200 m/s, for example. The length (11) of the central jet section and the difference in speed between the air speed and the fibre speed have to be taken into account to give the force transfer of about 0.1 N for a given type of glass fibre. The air speed has to be limited to the sound speed, to prevent compression beatings at the jet outlet. To give a force transfer of 0.1 N, the jet dia. (D) is 8mm, the length of the central (11) section of the jet is 3.4m, the difference speed u = umax - v = 150 m/s, and the air throughput is 21.8 kg/s.
