Patent NL-7705600-A (NL)
IPC: C25B13/06
Filed: 1977-05-20
Abstract: A method is disclosed forming a membrane over a standard diaphragm cell foraminous electrode and may comprise the steps of suspending a matting material in a liquid medium, inserting a foraminous electrode into the suspension, vacuum forming a layer of the suspended matting material over the surface of the foraminous electrode so as to substantially reduce the porosity of the foraminous electrode material, applying to the surface of the foraminous electrode with the matting material thereon; a layer of thermoplastic material which includes particles of perfluorosulfonic acid resin in the sulfonyl fluoride form, baking the foraminous electrode with the layers in place until the thermoplastic material is fused into a thin and uniform film on the surface of the matting material which is substantially permeable to hydraulic flow and hydrolyzing the perfluorosulfonic acid resin to change the sulfonyl fluoride form to the cation exchange sulfonic acid form. The forming of the membrane over a standard diaphragm cell electrode assembly eliminates substantial cathode costs involved currently for converting the diaphragm electrolytic cell to a membrane electrolytic cell.

Title: Compsn. for controlled release of trace elements - into water, esp. for optimised nutrition of animals
IPC: A23K1/175
Filed: 1981-07-20
Abstract: Compsn. comprises a relatively insoluble trace-element cpd. (A), pref. together with a binder, such that addn. to water results in a controlled level of dissolved trace element. Pref. (A) is a cpd. of Cu, Co, Mg, Mn, Zn, Se, Fe, Ni, As, Cr, V, iodine or F, and the binder is a cpd. which (a) gives a compsn. with a different solubility prod. from (A) alone; (b) forms a mouldable, hardenable compsn.; and (c) is non-toxic and stable with respect to lime, heat and water; specifically calcium sulphate hemihydrate.S Opt. the compsn. also contains a blocking-complexing agent to prevent fixation of trace element onto impurities, e.g. in the case of copper, 0.75-1 wt.% hexametaphosphate. It can also include cpds. which retard (e.g. silicone or stearic acid) or accelerate (e.g. ligno-sulphonate, reducing sugar, ethylene glycol or a basic cpd.) dissolution of (A). Compsns. are esp. used to introduce trace elements to animals, drinking water and allow the content of trace metal to be maintained at a constant optimum level without risk of toxicity. Since Cu is toxic to mollusis and algae, the compsns. can also be used to kill snails and trematodes (e.g. in trout or oyster breeding) and to clear out algae from waterways.

Title: Process for isolating a specific nucleotide sequence containg genetic information and transfer to a microorganism
Inventor: RUTTER WILLIAM J
IPC: C12N1/16
Filed: 1978-05-24
Abstract: New DNA transfer vector contains in its nucleotide sequence a sub-sequence having the structure of and transcribes from, a gene of a higher organism. Specifically the sub-sequence is the code for human insulin A or B chain (or both), or human growth hormone (the nucleotide sequences of these codes are given). Also new are microorganisms including in their nucleotide structure such as a sub-structure. - The microorganisms are made by first isolating an appropriate messenger-RNA; purifying it, then using it to elaborate a double-strand complementary DNA (c-DNA) contg. the required code. This is then reacted with a DNA-transfer vector having reactive end-groups able to react with itself or with the c-DNA. - The modified microorganisms can be used to produce insulin or growth hormone by fermentation, which is easier and quicker than cultivation of cell lines and gives better yields.

IPC: B29B11/16
Filed: 1989-11-03
Abstract: It is known to use small, light weight mesh pieces having high flexural recovery, to strengthen a matrix. Such mesh pieces are very difficult to handle and package. In order to provide a suitable packaging system, mesh pieces 11 are deposited across the width of a moving run of flexible wrapping material 13 and are deposited in longitudinally overlapping relationship along the length of the wrapping material, by feeding the mesh pieces 11 on a belt 10 which moves more quickly than the wrapping material 13; the mesh pieces 11 are ejected from the end of the belt 10 onto the wrapping material 13. The direction of movement of the wrapping material 13 is inclined downwards so that the trailing ends of the mesh pieces 11 contact the wrapping material 13 before the leading ends contact the preceding mesh piece 11. The wrapping material 13, with the mesh pieces 11 on it, is then rolled up under tension into a spiral bale so that the overlapping edges curl down and prevent the mesh pieces 11 slipping out.
