Title: Straightening rotationally symmetrical workpieces - by successively applying reducing forces to workpiece between two counter-bearings according to a specific formula
Inventor: FOERSTER JOACHIM
IPC: B21D3/10
Filed: 1987-03-28
Abstract: Method of straightening rotationally symmetrical workpieces consists of subjecting a length of the workpiece between two counter bearings (1) to a bending force (3). Starting from one end is individual sections, the radial distortion (M) at the mid-point between the berings (1) is measured and a bending force equal to M (l+k) is used with K being dependent on the distance between the bearings (1), the workpiece material its condition and temperature as well as its cross-section. After releasing this force, the residual distortion M2 is corrected by a force equal to M2 (l+k) where k' is given by kM1+M2, M1. Forces are repeatedly applied until the distortion is reduced to a tolerable amount. The workpiece is then moved so that the next section can be straightened. USE/ADVANTAGE - Bar straightening. Is inexpensive with regards to the apparatus used.
Patent DE-3711253-A1 (DE)
Title: Device for optical measurement of the oxygen saturation of blood in a living creature (organism)
Inventor: HATSCHEK RUDOLF A DR
IPC: A61B5/00
Filed: 1987-04-03
Abstract: The device has a holding device and two carriers, which are mounted detachably thereon and each have a measurement head (23). Each of the latter has an optoreceiver (33), light sources which serve to transmit light signals having different wavelengths, and at least one radiator (39) for the purpose of heating by the irradiation of waves the region of the body and, in particular of the skin where measurements are made during a measurement of the oxygen saturation of the blood. If the two measurement heads (23) are arranged during measurement on mutually averted sides of a body part (1), each optoreceiver (33) can pick up both reflected light backscattered in the body part (1) and transmitted light penetrating said part, and this gives a high accuracy of measurement. The power of the waves transmitted by the radiator (39) is regulated by a pulse width regulation in such a way that a magnitude which provides a measure for the changes, caused by the pulse, in the intensity of light which reaches at least one of the optoreceivers (33) from the said body region, has a prescribed desired value. This ensures adequate heating of the body region without giving rise to damage due to overheating. <IMAGE>

Title: Method for finishing valve needles for fuel-injection nozzles
IPC: F02M61/06
Filed: 1987-11-28
Abstract: In valve needles which are provided with a sealing cone (12) and a throttling pintle (18), the needle shape in the region of these portions has a great influence on flow tolerances of the fuel. To minimise the spread between units, i.e. to obtain greatest possible consistency of shape in large-scale production of valve needles, it is proposed to finish the said portions (12, 18) in a common operation by grinding using a shaped grinding wheel, in which the shape of the valve needle is produced by a diamond wheel. Preferred application area is injection nozzles for self-igniting internal combustion engines. <IMAGE>
Patent DE-3743760-A1 (DE)
Inventor: BORN HELMUT ING GRAD
IPC: E04F15/024
Filed: 1987-12-23
Abstract: Hitherto, sectional false floors have been produced from a trough- shaped body made of a material with high tensile strength and high modulus of elasticity and from a trough filling made of a material with low tensile strength and low modulus of elasticity, e.g. anhydrite. In the event of high point loading, the trough filling may be destroyed owing to its low tensile strength, whereas the trough is still able to carry load. The tensile, bending and edge strengths of the bearing slabs are to be increased and a method for their production which can be carried out in a small number of working steps without the previously required trough is to be provided. The bearing slab additionally contains a fibre material made of glass and/or steel, the fibre length being between 10 and 60 mm and the volume percent of the fibre material being 0.1 - 10 % by volume. The fibre material is added to the starting materials and this mixture is applied to the underside of a strong top covering. Used in the laying of service conduits. <IMAGE>

Title: Oxidic superconductor in wire form and process for its production
Inventor: KUMAGAI TERUO
IPC: H01L39/14
Filed: 1988-05-25
Abstract: The invention relates to a superconducting wire comprising a stabilised wire sheath of, for example, copper, aluminium or silver, which is filled with a superconducting oxidic material such as, for example, yttrium-barium-copper oxide. The sheath of the wire has microorifices which can allow gases and a cooling medium to pass through and thus to contact the oxidic material. The superconducting wire is produced by filling a metal sheath with a powder of a superconducting oxidic material, stretching the sheath to give a wire and subsequently heat treating the wire. The sheath is provided with the small orifices before or during the heat treatment step of the superconducting oxidic material. The wire thus gains an improved superconducting capacity. <IMAGE>

Title: Process for preparing a surface sizing agent
Inventor: GAIKOWSKI MANFRED DR
IPC: C08F8/32
Filed: 1988-06-11
Abstract: The preparation of the surface sizing agent for paper and board is effected by modifying 1.0 mol parts of an alternating alpha-methylstyrene-maleic anhydride copolymer which contains anhydride groups with from 0.7 to 1.0 mol parts of an aliphatic amine and from 0.9 to 1.2 mol parts of ammonia. According to the invention, a stirred vessel is charged with from 11 to 33 mol parts of water. At 10 to 80@C a 20 to 60% strength acetonic solution of alpha-methylstyrene copolymer as obtained by the free radical polymerisation of molar amounts of alpha-methylstyrene with maleic anhydride in acetone is stirred in. The acetone is then distilled off. Thereafter the aliphatic amine and ammonia are added as a mixture. After the dissolving of the polymer, the acetone still enclosed in the polymer is driven off. Thereafter the size is adjusted in a conventional manner with water to the desired size concentration. The advantage of the process is the avoidance of not only apparatus- but also labour-intensive powder technology.

Abstract: The invention relates to a rolling stand constructed without housings and without preloading. The invention is intended to improve the ability to function and increase reliability. The object is to create a rolling stand in which the chocks of the rolls are self-adjusting and cannot be displaced radially relative to one another but can be displaced axially and parallel to the rolling line in pairs, within certain limits. This is achieved by virtue of the fact that the chocks are connected in pairs and via flexible sealing elements and braced against the tie rods via articulation parts in a manner which has a weight-compensating effect by means of spring elements arranged at the ends of the said tie rods. <IMAGE>

Title: Setting device for the eyepiece of an endoscope
Inventor: UEDA HIROHISA
IPC: G02B23/24
Filed: 1989-03-10
Abstract: In a setting device for the eyepiece of an endoscope, which moves the optics 24 for dioptre adjustment along the optical axis, the optics 24 is automatically moved into a predetermined projection position inside the dioptre setting range when a supplementary device 200, e.g. a photographic recording device or an imaging device, is fitted on the eyepiece (22), irrespective of the present position of the optics 24 inside the dioptre setting range. The optics 24 is arranged in such a manner that it is opposite the emission surface 4a of a light guide 4 and that it can be moved forwards and backwards along the optical axis for dioptre setting. A setting device 28, 80 serves to move the optics 24 into the projection position and is actuated by fastening a supplementary device 200 to the eyepiece 22 so that the optics 24 is then brought into the projection position which is approximately in the middle of the dioptre setting range. This movement takes place from a position which can lie in front of or behind the projection position. A pre-setting device 106, 108 serves to bring the optics 24 before this setting movement in each case into one of these two positions which is defined as the starting position for the setting into the projection position which then follows. <IMAGE>
