Title: A process for the production of Halo-Alkenes
IPC: C07C17/093
Filed: 1967-05-15
Abstract: 1,181,873. Production of halo-alkenes. SOC. NATIONALE DES PETROLES D'AQUITAINE. 15 May, 1967 [18 May, 1966; 3 May, 1967], No. 22477/67. Heading C2C. Halo-alkenes, in which the molecule contains at least two halogen atoms, are obtained by treating with a halogen, an alkenyl thioester which satisfies at least one of the following two conditions: (a) the end carbon atom of the alkenyl chain, which is double-bonded, is substituted with one or two elements or groups which are donors of electrons; (b) the second carbon atom of the alkenyl chain, to which the said double bond extends, carries a group which is an attracter of electrons. The electrondonating element or group in the starting material may be halogen or an alkyl radical, or an aryl radical substituted in the ortho and/or para positions with a hydroxy, methoxy, carboxy, halo, phenyl, alkyl, alkylcarboxy or amido group, the electron-attracting group in the starting material may be an aryl group substituted in the meta-position with an electronegative group, e.g. nitro, cyano, sulphonic, acyl, carboxy or amido group, and the thioacid from which the thioester starting material is derived may be an aliphatic, alicyclic or aromatic thioacid. The reaction may be effected in an inert solvent at a temperature of- 30‹ C. to 100‹ C. and, when a mixture of tetrachloroproprene isomers is the product of the reaction they may be isomerized, e.g. in the presence of a Friedel-Crafts catalyst, to yield 1,1,3,3-tetrachloroproprene. In specific examples the products obtained are 1,3,3- and 1,1,3-trichloropropene, 1,2,3,3-, 1,3,3,3- and 1,1,3,3-tetrachloropropene, and 1,2,3,3,3-pentachloropropene, some pentachloropropane also being formed.

Abstract: 519,064. Dyes. DAVIES, J. S. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 29, .1938, No. 22688. [Class 2 (iii)] 1:11- Di-arylamino-3:3<1>-bis-isoindolenylidenes, which are new coloured compounds, are prepared by interacting 1:1<1>-di-(alkylmereapto) 3:3<1>-bis-isoindolenylidenes with primary aro-' matic amines, which may carry substituents other than nitro, sulpho and hydroxy groups. The products can be sulphonated. The reaction with the amines may be effected by heating the reactants together in the presence of tertiary aromatic amine or an excess of the primary amine or other liquid solvent or diluent. The products may be used as pigment colouring matters, or, when carrying suitable substituents, as lake-making intermediates or as dyestuffs for wool or acetate artificial silk. The sulphonation of the products can be carried out by stirring with concentrated sulphuric acid, or oleum, if necessary with heating. The sulphonated products may be used in lake-making or in dyeing animal fibres. The 1:1<1>-di-(alkylimercapto) 3:31- bis-isoindolenylidenes, which are used as starting materials may be made by treating the mercapto compound described in Specification 516,342 with alkylating agents. In the examples : (1). a mixture of 1:1<1>-di-(methylmercapto)-3:3<1>-bis-isoindolenylidehe (obtained, by treating the product of Ex. 1 of Specification 516,342 with dimethyl sulphate and alkali) and aniline heated to give 1:1<1>-dianilino-3-3<1>-bisisoindolenylidene; the aniline may be replaced by p-toluidine, o-chloraniline or p-phenetidine ; (2) 1:1<1>-di-(methylmercapto)-3:3<1>-bis-isoindolenylidene is heated with p-phenylenediamine and dimethylaniline to give the diamino derivative of the product of Ex. (1) ; (3) 1:1<1>-di- (methylmercapto)-3:3<1>-bis-isoindolenylidene is heated with anthranilic acid and dimethylaniline ; the sodium salt may be used for lakemaking and for dyeing acetate artificial silk in orange shades ; (4) as in (3), except that m-amino-benzoic acid is used instead of anthranilic acid ; the sodium salt dyes acetate artificial silk yellow shades; (5) the same as Ex. (3) except that p-aminobenzoic acid is used instead of anthranilic acid ; (6) the products from aniline, o-chloraniline and p-phenetidine are sulphonated, the sodium salts dye wool in orange shades ; (7) di-(p-amino-phenyl) ether, 1:1<1>- di - (ethylmercapto)" 3:3<1>-bis-isoindolenylidene (made in a similar way to the corresponding methyl compound but using diethyl sulphate instead of dimethyl sulphate) and dimethylaniline are heated together ; the corresponding dipropyl ether can also be used as a starting material (8) the product of Ex. (7) is sulphonated and gives a sulphonic acid suitable for making lakes and which dyes wool and silk in brown shades ; (9) 1:1<1>-di-(methylmercapto)- 3:3<1>-bis-isoindolenylidene, 2-amino-3-naphthoic acid and dimethylaniline are heated together ; the product, when sulphonated, dyes wool yellowish-scarlet shades.

Title: Sterilizing process and apparatus
IPC: A23L3/32
Filed: 1944-11-17
Abstract: A method of sterilizing a product having substantial thickness comprises bringing the product to sterilizing temperature by high frequency inductive heating means effective to heat all parts of the product uniformly and substantially simultaneously and thereafter maintaining the product at sterilizing temperature by subjecting it to an external application of heat for a sufficient time to ensure complete sterilization of the product.  Thus a continuous process for sterilizing surgical dressings is carried out in an apparatus comprising a high frequency generator for delivering the necessary current to a pair of electrodes, a heating oven or chamber adapted to receive products from between electrodes and a conveyer for receiving and carrying the products through the oven.  Specification 475,631, [Group XI], is referred to.ALSO:A method of sterilizing a product having substantial thickness comprises bringing the product to sterilizing temperature by high frequency inductive heating means effective to heat all parts of the product uniformly and substantially simultaneously and thereafter maintaining the product at sterilizing temperatures by subjecting it to an external application of heat for a sufficient time to ensure complete sterilization of the product.

Title: High-load bearing for bridges and similar structures
IPC: F16C33/22
Filed: 1978-05-26
Abstract: The bearing which can be subjected to high loading and is intended for bridges and other structures comprises an upper and a lower slab (2, 3) and an elastomeric cushion (4) which receives the load and is located between the slabs. The cushion (4) has a constricted portion on its periphery. The bearing is provided with means which prevent a translatory movement between the upper and lower slabs (2, 3), but permit a tilting movement between them. The invention provides a device (15, 16) to delimit or to prevent a lateral expansion of the base and top surfaces of the cushion (4) without preventing its periphery from bulging outwards. A bearing of this type permits, with the same dimensions, greater loading and ensures better stability. <IMAGE>
