Title: Versatile cost effective Bowden cable - has outer spiral tube of steel sheet hot press bonded to pref. fibre-reinforced low friction plastic film with per-fluoro-alkoxy adhesive
Inventor: WOELKI PETER DIPL ING
IPC: F16C1/26
Filed: 1990-11-29
Abstract: A Bowden cable system consists of an outer spiral tube, inner coaxial cable, and intermediate low friction polymer layer; the tube itself consists of a substrate and outer coating in the form of a low friction plastic film. This latter film is preferably PTFE bonded to its substrate with a perfluoroalkoxy adhesive, and preferably has fibre reinforcement(s).       ADVANTAGE - The product saves material and operations in its production. It is versatile, it enables a wide variety of filling materials to be used, reinforcements can be used, and the substrates chosen to suit the applications concerned. In an example, a laminate is used for the spiral tube, consisting of 0.5 mm etched stainless steel sheet bonded to a 0.15 mm film of PTFE emulsion polymer with 25 wt.% aromatic polyester filler, using heat and pressure plus a thin film of perfluoralkoxy as adhesive. The laminate is cut into strips 2.75 mm wide and then made into spiral tubing of i.d. 3.3 mm. The finished Bowden cable was tested at -40 -/+ 150 deg.C under loads of 120-800 N, with amplitude +/- 50 mm, frequency 1 Hz and at least 1,000,000 cycles. After 3,000,000 cycles the test showed 91.2% effectiveness over the complete path, with 0.82 mm stroke in tension and pressure.       (Dwg.3/3)

Abstract: Pyridine-free titration agent for Karl-Fischer determn. of water contains a base, SO2, I2 as titrand and a solvent. It is in the form of a 2-component system. It contains Na acetate as base in a base/SO2 molar ratio of 1:0.5 and a stabiliser, which is a metal chelating agent, pref. EDIA.Na2 in concns. of 0.060-0.600 g/l, a substance displacing MeOH sterically, pref.  ethylene glycol monomethyl ether is concns. of 1.0-10.0 ml/l and/or an acetic ester capable of favouring the chemical equilibrium in the direction of the starting materials, pref.  methyl acetate in concns. of 1.0-10.0 ml/l. The titrand contains 0.3 mole I2/l MeOH. USE/ADVANTAGE - The reagent is used for determining the water content of pharmaceuticals of various types, suppository compsns. polyacrylate films and membranes, serulates and vaccines, fillers for phosphor prodn. (Al fluorides) and in catalysts (Al hydroxyfluorides) to determine their catalytic activity. The stabiliser inhibits the decomposition reaction (ester exchange of the acetate with MeOH) in the Karl-Fischer soln. The reagent is produced on the industrial scale and kept for long periods (at least a year at room temp.). Eliminates the drawback of analytical inaccuracy caused by too high a consumption of titrand in the blank test and low stability under the conditions of transport and storage.

Patent DE-4118523-A1 (DE)
Inventor: GOETSCHMANN NORBERT DIPL ING
IPC: G02B7/00
Filed: 1991-06-06
Abstract: A joint (1, 3, 2) consists of at least three joint parts preferably made of different materials and therefore having different coefficients of thermal expansion,  alpha . To ensure optimal compensation of the mainly radial differences in deformation induced by changes in temperature, it is proposed that at least a second joint part in the form of an intermediate ring (3) be provided between a first joint part - for example an optical lens (1) - and a second joint part - for example a lens mount (2). The thickness and material (coefficient of thermal expansion  DOLLAR (a)R) of the ring are chosen so that the above-mentioned deformation phenomena specific to the material and induced by temperature changes in the joint (1, 3, 2) cancel each other out, thus allowing stress-free or low-stress mounting of microoptical systems (1) for use in optical polarization devices.

Title: Electronic reproduction colour contrast increasing circuit - corrects colour signals exceeding threshold to threshold value and varies other signals to maintain constant colour relationship
Inventor: TATARI MEHMET SEHRAN DR ING
IPC: H04N1/58
Filed: 1992-08-01
Abstract: Colour signal (ROR'GOR'BOR) representing the pixel colour distribution are obtained by pixel and line-wise optoelectronic scanning of a master picture. Field signals (RTP'GTP'BTP) are generated which represent the colour distribution of the pixel surroundings. Colour difference signals (r', G', B') are formed from differences between the original signals and the field signals. The difference signals are weighted and added to the original signals to obtain contrast corrected signals (RST'GST'BST). To reduce errors in improving contrast the corrected signals of individual channels (1,2,3) are checked to see if they exceed a given threshold (14). If at least one signal exceeds the threshold (14) permissible difference signals are set as the distance between the original signal and the threshold (14). New difference signals (ARneuAGneuABneu) are provided from the permissible and the normal difference signals to maintain the ratio between the latter and the new difference signals. The latter and the original signals (ROR,..) are combined to provide new corrected colour signals (RK,GK,BK). ADVANTAGE - Allows optimal contrast correction without interfering colour errors.
