Title: Electrochemical oxidn. of alkyl-pyridine(s) to carboxylic acids - in cell with anion exchange membrane, acid anolyte and more dilute acid catholyte
IPC: C25B3/23
Filed: 1985-09-11
Abstract: Electrochemical oxidn. of an alkylpyridine of formula (I) is effected in an acid medium at a Pb-contg. anode of an electrolytic cell, with anode and cathode compartments sepd. by an anion-exchange membrane. As catholyte, an aq. soln. of the same acid as used for the anolyte but in relatively dilute form is used. The prod. is recovered from the anolyte. R=1-6C alkyl; n=1, 2 or 3. The acid used is pref. H2SO4, with 10-50 wt.% acid in the anolyte and 0.1-5 wt.% in the catholyte. The anion-exchange membrane is pref. non-porous, and has a high degree of selectivity for the transfer of monovalent anions. (I) is typically alpha- or beta-picolines, 2,3- or 2,6-lutidines or 2-ethyl-5-methylpyridine to give respectively, picolinic, nicotinic, 2,3-, 2,6- or 2,5-pyridinedicarboxylic acids.

Title: Beam tracking system for optical record player - controls tracking by moving coil movement on focus lens mounting
IPC: G11B7/09
Filed: 1988-02-22
Abstract: A beam of coherent light from a laser (13) passes through a diverging lens (14) to a fixed angled mirror (15). The reflected beam is focussed by a converging lens (16) onto the track on the rotating record e.g. video disc, (11). The light which passes through the record falls onto a photodetector (17). The photodetector output is fed to a signal processor (18). The processor produces two signals: the replayed recorded data (V) and a tracking control signal (C). The tracking control signal (C) is converted to a coil drive signal (M) by another circuit (19). The coil is at right angles to the beam path and is in the field of a permanent magnet. The signal causes the lens to move sideways and thus keeps on track.

Title: Polymerisation of olefin using Ziegler catalysts - and activators giving extended activity and reduced gel formation (NL 9.1.78)
IPC: C08F10/02
Filed: 1989-01-27
Abstract: Prepn. of polyolefins comprises polymerisation of ethylene opt. together with an alpha-olefin CH2=CH4 (in which R is 1-6C alkyl), and a linear or cyclic diene or polyene ter-monomer, in presence of a catalysts system of (1) an organic Al cpd., (2) a 3-5 valent V cpd. soluble in inert organic solvent, and (3) an activator consisting of either (A) an ester of formula CX3COOR' (in which R' is a linear or cyclic gp with an ether bond, and X is halogen), or (B) a reaction product of PCl5 with a alcohol. Pref. (1) is of formula R"nAlX3-n, (in which R" is an 1-20C hydrocarbon gp.; X is halogen; n is 1-3). (2) is a V halide, oxyhalide, complex with O-contg. cpd. or a vanadyl ester. Used for prodn. of thermoplastics and synthetic rubbers of known types. Addn. of activator (3) to the Ziegler catalyst system gives increased activity which is maintained over longer reaction times, and allows use of much less V cpd. (2). No gel formation occurs when a polyene termonomer is used, in contrast to known activators such as alkyl esters of trichloro-or tribomo-acetic acid.

Title: Urinal with attachment bracket
IPC: E03D11/16
Filed: 1991-11-29
Abstract: A urinal is provided with an attachment bracket for attaching the urinal to a wall. The attachment bracket comprises an elongate plate which can be attached substantially flat against the wall and fits into the concave rear side, which is to be attached to the wall, of the urinal. Holes are formed in the side walls of the urinal in order to receive bolts which are able to interact with the ends of the attachment bracket. These ends are bent away from the wall in such a manner that the urinal can be clamped against the wall by tightening of the bolts. For this purpose, at least one end of the attachment bracket is provided with a threaded hole in which the relevant bolt engages, with the result that there is no longer any need for separate nuts. During tightening of the bolt, the end bends elastically towards the wall, about a rotation line or zone, over a certain distance within the hollow rear side of the urinal.

Title: Method for sequestering ecologically harmful substances from material contaminated with such substances
IPC: B01J20/12
Filed: 1993-05-27
Abstract: A method is described for sequestering ecologically harmful substances, both organic and inorganic, by absorbing these substances on a swellable, layered clay modified with hydroxyaluminium to form a pillared clay having pillars of aluminium hydroxide complexes, said clay prior to absorption having been treated with a salt of an inorganic acid, preferably with a phosphate. If the treatment is carried out with a salt of a rare earth element, superpillars are formed in the clay, thus affording a clay having great absorbency as well as a high rate of flow through it. As a result of the pillared clay being treated with a quaternary ammonium compound, a doubly modified clay is formed which is eminently suitable for treating material which is contaminated with a combination of organic and inorganic ecologically harmful substances.

Inventor: SPAECK HELMUT
IPC: H01H33/64
Filed: 1990-05-11
Abstract: A metal-encapsulated and gas-insulated load switching device has a three-position switch (4) for the 'on', 'off' and 'earthed' positions and a vacuum power switch. Here, with the three-position switch (4) in its 'on' position, there is a series connection with the vacuum power switch (11) such that the three-position switch (4) is connected to the busbar side and the vacuum power switch (11) to the output side. The output side is directly earthed with the three-position switch (4) in the 'earthed' position. In this circuit, short-circuit currents are contolled without any additional interlocks as there is a three-position switch designed as a load separating and earthing switch which is also capable of switch-on on a short circuit. The space provided for the vacuum switching tubes (12) can be of such a size that fuse chambers can also be used for HCBC fuse inserts. It is thus possible to create modular units of the same size with different switchgear for the most common switching purposes.
