IPC: C08F8/46
Filed: 1967-12-21
Abstract: 1,148,855. Treating olefin copolymers. FARBWERKE HOECHST A.G. 1 Jan., 1968 [31 Dec., 1966], No. 48/68. Heading C3P. Halogen and free or functionally modified carboxylic acid groups are introduced into a copolymer produced by low pressure copolymerization of at least two aliphatic or cycloaliphatic mono- or di-olefins, preferably containing 2 to 10 carbon atoms, by reacting the copolymer with halogen and an aliphatic or cyclo-aliphatic carboxylic acid anhydride unsaturated in α-position, or a functional derivative of such an acid. The reaction may be effected in the presence of 0À05 to 5À0 per cent by weight of the copolymer of a free radical liberating agent, or while irradiating with ultraviolet or high energy radiation. The copolymer may be derived from ethylene, propylene, butene-1,2-methylpentene, vinyl cylcohexene, dicyclopentadiene, isoprene and butadiene. The acid compound may be maleic or aconitic anhydride, maleimide, an ester of maleic or fumaric acid or an acid chloride. The radical liberating agent may be azodiisobutyronitrile, dibenzoyl peroxide or di t-butyl peroxide. The reaction may be effected in an inert solvent, e.g. chlorobenzene, o-dichlorobenzene, choloroform and carbon tetrachloride. Examples describe the reaction of ethylene/ propylene with chlorine and (1 and 2) maleic anhydride in chlorobenzene, (3) maleic anhydride in carbon tetrachloride, (4) diethyl maleate in chlorobenzene and (5) cis-anhydro-aconitic acid in chlorobenzene, all in the presence of ultraviolet light. The products of (1) and (5) are cross-linked with ethylene diamine.

Patent NL-7705619-A (NL)
Title: Aeration of effluent in a treatment basin - which includes a flotation device for inspection and maintenance
IPC: B01F7/00
Filed: 1977-05-20
Abstract: Effluent is aerated and the aerated effluent is circulated through a treatment tank. The aerating and circulating device consists of a propellor mounted on a vertical shaft driving the effluent upwards through the rotors and thence through a series of ducts which direct the flow upwards and outwards. On the suction of the propellor is a basket mounted on the same shaft which is connected to an air compressor. The air issuing from the basket is entrained in the upward flowing stream of effluent passes through the propellor blades where a certain proportion of the bubbles is broken into smaller bubbles and is then carried with the stream of effluent up into the treatment basis. At the surface, the coarser bubbles pass into the atmosphere, but the finer bubbles are carried back with the circulation of the effluent down the outer wall of the basin and back into the suction of the propellor. The entire appratus is attached to a flotation chamber so that it can be floated to the surface for inspection and maintenance purposes. Existing processes for aerating treatment basis consist either of surface agitators which entrain surface air by means of mechanical agitation, a process which is noisy inefficient and cannot operate when the surface is frozen or of air distribution systems immersed in the basin which are liable to blockage and are difficult to maintain. The above system overcomes the disadvantages of the traditional equipment.

The lamp consists of a cylindrical discharge tube (4) housed concentrically in an outer cylinder (6). The space between them is filled with a gaseous heat conducting medium to conduct heat away from the discharge to the outer air. To control the direction of emission of light, the outer envelope is covered with a diffusely reflecting layer (18) and a longitudinal slit along which the light issues.
Patent NL-7902504-A (NL)
Title: Frame with grid-like shelves for mushroom propagating beds - has inverted channels extending between inverted tee profile members
IPC: A01G1/04
Filed: 1979-03-30
Abstract: The long members extending between the cross-members of a frame and forming a grid for supporting mushroom propagating beds, are "U"-profiles. They have their open sides facing downwards and their length corresponds to the distance between the cross-members in the frames. Plates at suitable spacing project horizontally from the cross-members and ribs on the inside of the legs of the "U" rest of these. The cross-members are hollow profiles with the cross-section of an inverted "T", and are bolted to angle brackets on the rectangular tubular uprights. Erection of the grids is simplified considerably, as compared with designs using ten-metre-long tubes, whilst the interruption of the uniformity of the flow of air caused by these tubes is eliminated. The inverted channels trap the air currents set up so that uncontrolled swirling around the grids is prevented.

Title: The irradiation of povidone and povidone-iodine
IPC: A61L2/08
Filed: 1983-05-26
Abstract: Povidone is sterilized by irradiation in the presence of iodine and iodide ions. In particular solutions of povidone are sterilized by gamma-irradiating the povidone in the presence of iodine and iodide ions, which are present in an amount which prevents gelation at that dose of gamma radiation which would cause gelation in the absence of the iodine and iodide ions. The gamma irradiation of povidone may be effected in the presence of iodine with both iodide and iodate ions or as povidone-iodine in the presence of iodide and/or iodate ions. Sterilization thus effected by gamma radiation while preventing gelation of the povidone and degradation of the povidone-iodine.
