Title: Omega-alkylmercuricthio fatty acids, derivatives thereof and process for their preparation
IPC: C07F3/10
Filed: 1959-01-23
Abstract: The invention comprises omega-alkylmercuric thio-fatty acids of formula:  <FORM:0855699/IV(b)/1> wherein R is C2-C4 alkyl, and n is 4 to 12 inclusive, and esters and metal salts thereof.  They may be prepared by reacting the corresponding omegamercapto fatty acid or an ester or salt thereof with an alkyl mercuric compound of formula RHgX when R is C2-C4 alkyl and X is a halogen atom, a hydroxyl group or the residue of an inorganic acid or fatty acid. Specified are the alkyl mercuric hydroxides, chlorides, bromides, phosphates, sulphates, acetates and propionates.  A solvent such as water, or a lower aliphatic alcohol or ketone is preferably used.  The compounds of the invention have anti-bacterial and germicidal properties.  The following compounds are prepared in the examples: omegaethylmercuric thio-undecanoic acid; (2) sodium omega-n-butylmercuric thio-undecanoate; (3) omega-ethyl mercuricthio tridecanoic acid; (4) omega-ethyl mercuricthio-n-valeric acid and (5) omega-ethyl mercuricthiocaproic acid.  Omega-mercapto fatty acids may be prepared by addition of thioacetic acid to an unsaturated fatty acid having a double bond at the omega position, and hydrolysis of the so-formed omegaacetylthio fatty acids.  Example 1 describes the addition of thio-acetic acid to molten undercylenic acid to form omega-acetylthioundecanoic acid, and the hydrolysis of this acid with sodium hydroxide to give omega-mercapto undecanoic acid.

Title: Coupling union for filter elements
IPC: B01D29/41
Filed: 1964-01-22
Abstract: A coupling union, e.g. of a plastics material, for spacing apart the inner peripheries of the two portions of a leaf filter element, e.g. as disclosed in the parent Specification, is made so as to permit adjacent elements to be fitted together and, preferably, interlocked, so that a stack of elements of indefinite extent may be assembled. The union consists of two annular sections 10, 10a, Fig. 2a (not shown), aligned coaxially. The meeting rims which are located within an element have interengaging teeth and recesses so arranged that these may be snap-fitted in one (angular) juxta-position.  The rims of the union which face outwards towards adjacent elements have spikes on their surfaces to engage and hold the two positions of sheet filter material constituting the element.  In addition, the inner periphery of section 10a has an upstanding collar 30 with an out-turned lip 32 at its top, and the inner periphery of section 10 has an in-turned lip 16.  Thus, adjacent elements may be snap-fitted together in any angular juxta-position.  The inwardly-facing rims of a union have further, opposing, recesses which on assembly form port-holes for flow of filtered liquid to the interior of the stack. As in the parent Specification the stack may be surrounded by a slotted sheet of paperboard bent and stapled into a tube to form a cartridge, which may be located in a casing.  Again, as in the parent Specification, the stack may be arranged about a perforate outlet pipe in a casing.  The snap-fitting (but not the inter-engaging) of the meeting rims located within an element may be omitted, and/or the snap-fitting (but not the inter-engaging) of the outwardly-facing rims may be omitted.

Abstract: 1299177 Laminated resin-fibre composites CIBA GEIGY (UK) Ltd 2 Jan 1970 [17 Jan 1969] 2880/69 Heading B5N [Also in Division D1] A reinforced composite is made by contacting a solid film of a thermosettable resin composition with strands of unidirectional reinforcing material comprising glass, boron or carbon fibres under such conditions that the resin flows around the strands, e.g. by applying heat and/or pressure. The resin may be subsequently cured by further heating. The reinforcement may be in mat or bundle form. A strippable polyethylene or paper backing may be provided for the resin film at the face opposite the strands, and the film may be given a tacky surface by coating with a curable substance, e.g. phenolic resin, which is tacky at room temperature. Further layers of resin and strands may be present. In batch operation, the reinforcing strands may be laid under tension on one film and a second film is then applied prior to pressing with heat. In continuous operation, either (i) a resin film is contacted with reinforcing strands which are supported on a strippable backing, the backing is removed, and a second resin film is applied, or (ii) supported films are simultaneously applied to each face of a reinforcing strand layer. The thermosetting resin may include particles of thermoplastic resin; specified compositions are: (a) phenolformaldehyde resole and polyvinylacetal or nylon, (b) phenol-formaldehyde novolak with neoprene or acrylonitrile rubbers, (c) epoxy resin with phenoxy resin, polysulphone or α-olefincarboxylic ester copolymer. The resin may contain powdered silica and dicyandiamide or hexamethylene tetramine, and may be cured to the B-stage to permit shaping of the article before final cure to the C-stage. Other sheet materials can be included as reinforcements, aluminium foils and honeycombs and resinimpregnated glass fibre mats and fabrics being used in examples; sheets of steel, titanium, nylon, polyimide, polysulphone, polycarbonate, natural rubber, neoprene and acrylonitrile rubber are also mentioned.

Patent GB-770707-A (GB)
Title: Process for the production of aluminium trialkyls and alkyl aluminium hydrides
IPC: C07F5/06
Filed: 1955-02-01
Abstract: Activated aluminium is reacted with olefins and hydrogen under pressure to give aluminium trialkyls and alkyl aluminium hydrides. The aluminium may be activated by grinding or comminution in the absence of moisture and air in a dry inert gas, e.g. nitrogen or argon, in order to prevent formation of a passive oxide layer on the surface.  The surface of the aluminium may be wetted during grinding with a nonoxidizing liquid such as a hydrocarbon solvent or the olefin to be used in the reaction.  It may also be comminuted under the aluminium trialkyl or dialkyl aluminium hydride to be produced in the synthesis reaction, or under a mixture of the aluminium trialkyl to be produced and the olefin to be used.  The ground aluminium may be conveniently reacted with a zinc alkyl or alkyl magnesium halide or other compound more sensitive to air than aluminium and which is compatible with the final reaction product prior to reaction with the olefin and hydrogen.  If desired, the aluminium may be melted and atomized in an inert gas stream.  Alternatively it may be activated by catalysts, for example, alkyl aluminium halides, preferably the sesquihalides.  The alkyl aluminium hydrides may be converted to the aluminium trialkyl by further addition of olefin.  Any hydrocarbons present in the reaction mixture may be removed by distillation under atmospheric pressure or under vacuum.  Iodinecontaining catalysts may be removed by distillation, but those containing chlorine or bromine can only be distilled from the product by high vacuum distillation. Those containing chlorine may be removed by heating and stirring with metallic sodium.  In the preparation of aluminium alkyls other than triisobutyl aluminium, the reaction products may be recovered by heating with potassium chloride or bromide equivalent to the halogen content of the reaction mixture.  Complexes are produced which form an oily layer beneath the required aluminium alkyls. In the preparation of triisobutyl aluminium, the reaction mixture may be cooled to 0 DEG C. or lower, the catalyst remaining liquid and the triisobutyl aluminium crystallizing out.  Suitable olefins are a -olefins such as propylene, a -octylene, and assymetrically-substituted ethylenes of formula R1R2C=CH2 such as isobutylene and 2-methyl-pentene-1.  In an example aluminium powder is ground with triisobutyl aluminium in a ball-mill filled with nitrogen, the suspension transferred to an autoclave and allowed to settle. After the clear supernatant triisobutyl aluminium is drawn off, isobutene and hydrogen are passed in under a pressure of 200 atmospheres.  The autoclave is rotated and heated to 110 DEG  to 120 DEG  C. until reaction is complete, as shown by a marked drop in pressure.  After cooling the gaseous products are vented, triisobutyl aluminium remaining behind.  Specifications 713,081, 742,642 and 763,824 are referred to.
