Title: Process for producing secondary alkyl-substituted aromatic hydrocarbons
Inventor: HERVERT GEORGE LADISLAV
IPC: C07C5/27
Filed: 1958-04-01
Abstract: Secondary alkyl aromatic hydrocarbons are prepared by the isomerization of a tertiary alkyl aromatic hydrocarbon having at least five carbon atoms in the tertiary alkyl group by subjecting it to the action of 0.1 to 35% by weight of aluminium or zirconium chloride or bromide at 0-75 DEG  C. The catalyst may be promoted with a hydrogen halide, the halogen of which is the same as the halogen in the catalyst.  The tertiary alkyl group preferably contains 9-18 carbon atoms, as in the case of an alkyl aromatic prepared by the alkylation of an aromatic hydrocarbon with a monoolefine such as a propylene tetramer fraction. The aromatic nucleus may be benzene, napthalene or anthracene and may contain other alkyl substituents, including other tertiary alkyl groups.  An inert diluent is preferably present and this may be a normal paraffin or a naphthene boiling below the temperature of the feed and product, such as n-pentane, n-hexane, n-heptene or cyclohexane or an aromatic hydrocarbon such as benzene or toluene, preferably one which corresponds to the charge stock less any tertiary alkyl groups.  In such cases transalkylation may take place if more than one alkyl group is present in the feed. The diluent may be used in a molar ratio to the feed of 0.5-6:1 and preferably in an amount at least equal in volume to the feed.  The reactants are preferably maintained in the liquid phase by increasing the pressure if necessary up to 3.5 atmospheres.  The secondary alkyl-substituted product may be separated by distillation.

Patent GB-527520-A (GB)
Title: Improvements in the treatment of textile materials with synthetic resins
IPC: D06M15/51
Filed: 1939-04-13
Abstract: 527,520. Treating textiles with liquids ; resinous condensation &c. products ; cellulose derivative compositions. ROHM & HAAS CO. April 13, 1939, No. 11253. Convention date, June 1, 1938. [Classes 2 (ii), 2 (iii) and 15 (ii)] Aqueous dispersions of synthetic resins or cellulose ethers containing an addition of a non-hardenable alkyd resin are applied to textiles in processes for improving the appearance, feel, handle, body, crush-resistance and other properties. The textiles may be padded with a mixture containing a hardenable resin and a non-hardenable alkyd resin in aqueous suspension, the total resin content being less than 5 per cent. of the mixture. Non-hardening alkyd resins include those from long chain polycarboxylic acids such as sebacic acid, and those containing a sufficient quantity of a non-drying fatty oil chemically combined with the other constituents of the resin to impart softness. Resins from glycerine and sebacic acid, glycerine, diethylene glycol, castor oil and sebacic acid, glycerine, sebacic acid, and phthalic acid, glycerine, castor oil, and phthalic acid, and from castor oil, maleic acid, and pine oil, may be used. Adipic, pimelic, suberic, or azelaic acid may be used instead of sebacic acid in forming the non-hardenable resin. These resins may be used in conjunction with urea-formaldehyde, urea-formaldehyde alcohol, hardenable alkyd, acrylic and methacrylic resins, and cellulose ethers. The pH of the dispersion of soft resin is preferably at or about the neutral point. In an example, castor oilglycerol-sebacic acid resin is mixed with a solution of sodium di-isobutyl phenoxyethyl sulphate. Caustic soda solution and water are added and a stable emulsion is produced. This emulsion is mixed with an aqueous emulsion of urea-formaldehyde-butanol resin. Broadcloth is padded with the diluted emulsion, dried and heated. The fabric has a soft, full hand and silky touch. In another example, the emulsion of soft resin is mixed with an emulsion of a co-polymer of methyl and ethyl acrylate and the mixture is used for padding cotton fabric. In another example an emulsion of castor oil-glycerol-sebacic acid resin is mixed with an emulsion of urea-formaldehyde resin, or of an organic solvent-soluble ethyl cellulose plasticized with hydrogenated rosin ester. Spun rayon and cotton, or spun silk and cellulose acetate fabrics are padded with the mixture. Cotton fabric is padded with a mixture of phthalic anhydride-glycerol-sebacic acid resin emulsion and polyethylacrylate emulsion. Cotton suiting is treated with a mixture of drying oil-glycerol phthalate resin emulsion and terpineol-pine oil-glycerol-maleic anhydride resin. Specification 525,190 is referred to.

Title: A circuit for sequentially operating a series of devices connected to the circuit
IPC: G08B29/14
Filed: 1966-03-15
Abstract: 1,139,981. Electric selective signalling. E. W. BLISS CO. 15 March, 1966 [7 July, 1965], No. 11303/66. Heading G4H. An arrangement (A) for sequentially operating a series of remote stations (C,D,E), Fig. 1 (not shown), comprises a series of bi-stable relay units, each controlling one station. Each bistable is normally in one state, but when switched to the other state operates the associated remote station. The bi-stables are connected to a source of pulses of opposite polarity, and each successive bi-stable in the series is switched to the other state in response to alternate opposite polarity pulses applied through normally open contacts of the preceding bi-stables in the series. Each remote station transmits a distinctive coded signal by open-circuiting the loop upon closure of a switch (S) at the relevant station. A signal from the central station control F, Fig. 2, energizes in sequence each of a series of relays J,K,L, associated with the remote stations, causing the remote stations to be disconnected from the loop without breaking the loop, or to transmit their coded signals for test purposes. Each relay coil J,K,L of the series is connected to an associated control unit G,H,I. Operation of a switch S1 reverses the voltage fed to the first control unit G and sets a counter CI at the control station to 1. Subsequent operation of the switch S1 energizes the first relay J. After a delay, set by a thermistor, the circuit operates to reverse the voltage again, the counter is stepped to 2, the current in the first relay J ceases and the second control unit H is enabled, current then flowing in the second relay K. The sequence continues for the third control unit, and after a delay the complete circuit is returned to the quiescent state.
