Patent DE-3830119-A1 (DE)
Title: Optical coupling device
Inventor: SCHMID PETER DIPL PHYS
IPC: G02B6/42
Filed: 1988-09-05
Abstract: The optical coupling laser-waveguide or waveguide-waveguide, for example in transmitter modules, requires great outlay in terms of adjustment. A coupling device is here proposed, in which an aspheric plano-convex lens is fitted directly to the place where the light leaves a laser or a waveguide. The lens is either glued to the spot where the light leaves or is attached to the carrier element. A lens which is pressed from plastic or glass forms a particularly cost-advantageous solution. <IMAGE>

Abstract: The invention relates to an articulation body for a partition wall, having at least two partition-wall elements which are connected, at the vertical butt-joint locations, in alignment or at largely any angle. The articulation body is characterised by two articulation pieces which can be interconnected and moved relative to one another on an arc of a circle and of which one can be connected to the narrow side of the first partition-wall element and the other can be connected to the narrow side of the second partition-wall element such that the spacing of the arc of the circle from the front, non-spaced-apart side edges of the mutually facing narrow sides of the adjacent partition-wall elements is constant.
Patent DE-3900089-A1 (DE)
Inventor: MOECKESCH ERICH
IPC: B67D1/04
Filed: 1989-01-03
Abstract: A process for filling a tank (1) with carbonated beverages, particularly beer, which tank contains a film bag (5) to be filled with the beverage from below and is provided at the top with a connection fitting (3) which permits the escape and entry of a gas, the air situated between the outside of the film bag (5) and the tank wall (18) being expelled, when filling the film bag (5) with the beverage, via the connection fitting (3) due to the expanding film bag (5) until, for safety reasons, only a preset remaining space (17) remains between the film bag (5) and the tank wall (18), is to be developed further in such a way that it is possible, when filling conventional tanks (1) containing film bag (5), to fill the remaining space (17) only with CO2 or a CO2/air mixture, the oxygen content of which is negligible. This is achieved in that the air situated in the remaining space (17) is replaced by a gas, particularly carbon dioxide (CO2), which behaves neutrally with respect to the beverage or is mixed with the neutral gas to such an extent that the oxygen content, due to the air, in the mixture is less than a preset minimum value. The invention also includes devices for carrying out the process. <IMAGE>

Title: Method of controlling the movement of a car unit of a lift, and car unit
Inventor: NOUSIAINEN ILKKA
IPC: B66B7/04
Filed: 1989-03-28
Abstract: In a method with which the movement of a car unit along guide rails is controlled, the lateral movement transmitted from the floor of the car (37) to a user is reduced to a minimum. In the method according to the invention, the lift movements are controlled in such a way that the swing of the car, which is caused by a lateral displacement of the car unit or a part of the same, takes place about a rotation axis (A) which lies at the level of the car floor or near it. <IMAGE>

Patent DE-3926655-A1 (DE)
Inventor: PARK BUM-CHUL
IPC: H02J7/02
Filed: 1989-08-11
Abstract: Different focus voltages (VA1, VA2, VA3) are applied to respective electrodes (G3-G7) forming unipotential auxiliary lenses, in such a manner that they should have gradually diminishing potential differences in the electron travel direction. Focusings at the auxiliary lenses are attenuated, and therefore, the variations of the electric fields and the consequent variation of the characteristics of the beam spots due to the processing error of the electrodes are thereby lowered. <IMAGE>
Patent DE-3926859-A1 (DE)
Inventor: BEYER ECKHARD DR ING
IPC: B23K26/04
Filed: 1989-08-15
Abstract: In a process for machining workpieces (10) using a laser beam (11), in particular for cutting, perforating and removing material from metallic workpieces (10), the machining site (12) of the workpiece (10) is monitored by means of a beam detector (13) by means of which the intensity of the laser beam is reduced when an upper limit value (14) is reached and increased when a lower limit value (15) is reached. In order to obtain a simply controlled process without exceeding a critical temperature, e.g. the evaporation temperature, the beam detector (13) measures the radiant heat (16) emanating from the machining site (12). This radiant heat is controlled in function of a predetermined range of temperature, the upper temperature of which is the upper limit value (14) and the lower temperature of which is the lower limit value (15). The laser beam is switched off when the upper limit value (14) is reached and switched on again when the lower limit value (15) is reached.

Patent DE-3940850-A1 (DE)
Inventor: GOTTSCHALK KARL-HEINZ DIPL ING
IPC: D06C3/02
Filed: 1989-12-11
Abstract: The invention relates to a method for setting a uniform and specific tension in running material webs, such as textile webs or the like, guided with width stretching through a treatment space, especially a dryer, in which the material webs are first introduced without width stretching into tensioning elements which are arranged on tensioning chains guided in chain tracks, and are subsequently width-stretched by a width adjustment of the chain tracks, and is aimed at guaranteeing an always specific tension in all the parts of the material web. For this, it is proposed, according to the invention, to guide the material webs (10) through the treatment station so as to be held elastically flexibly in the width-stretching direction, for example in that the tensioning elements (14), such as needle bars or tenter clips, arranged on carriers (13) on the tensioning chains and held in an end position in the width-stretching direction of the material web, are mounted on the carriers in an elastically displaceable manner.

Title: Pigmentation of polyurethane or polyurea components - in which component is dipped into soln. of black pigment in acetone and then dried
Inventor: SCHAPER HERBERT DIPL CHEM DR
IPC: D06P3/24
Filed: 1990-05-03
Abstract: Process is for pigmenting polyurethane or polyurea components in a black colour and is suitable esp. with prods. mfd. from recycled materials of the type mentioned.

Title: Oil from polyurethane foam waste - produced by absorbing compressed waste in partially recycled hot oil
Inventor: SCHMID KARL
IPC: B29B17/00
Filed: 1990-09-10
Abstract: Polyurethane foam waste is liquified into monomer by stirring it into hot oil at 210-230 deg.C., the oil being the prod. of previously decomposed waste. The waste can first be chopped, stored and consolidated to prevent gas emissions. Polyurethane foam waste is chopped (1) to 10-20 mm size and stored (3). It is preheated and compressed (5) and then fed to stirred reactors (7,8) which are at slightly different levels so that the second reactor only contains oil. Part of the oil is recycled by a pump to the first reactor and the rest is fed to a store (16,17). The main atomising burner (14a) is fed via an oil filter (20). USE/ADVANTAGE - The process allows the high calorific value of waste to be utilised without contamination and polluting gas emissions. (10pp Dwg.No.2/6)

In an example, beta-alanine ethyl ester (18.8g) and NaHCO3 (25.2g) in MeCN (100 ml) were treated with a soln. of 5-methylisoxazole-4-carboxylic acid chloride (21.8 g) in MeCN (30 ml) at such a rate that the temp. did not rise over 50 deg.C. After stirring for 6 hrs. the mixt. was worked up chromatographically to give N-(2-ethoxycarbonylethyl) -5-methylisoxazol-4-carbaxamide, m.pt. 48-50 deg.C. N-(5-methyl-4-isoxazolyl carbonyl)-5-aminovaleric acid had an LD50 (i.v.) in rats of above 630 mg/kg, better than acetyl-salicylic acid (495 mg/kg).
