Abstract: 1,143,863. Dimerizing alpha-olefins. BRITISH PETROLEUM CO. Ltd. 16 Nov., 1967 [10 Jan., 1967], No. 1244/67. Heading C5E. Alpha-olefins are dimerized to a product consisting predominantly of linear dimers having an internal double bond in the presence of a catalyst comprising a complex organic compound of a Group VIII metal (Mendeleef) and an activating agent at - 40‹ to +200‹ C. under such conditions of pressure that. the reactants are maintained in the liquid or partially condensed phase, the two catalyst components being mixed in the presence of the olefin to be dimerized. Several methods of achieving this are mentioned. The preferred complex organic compound is nickel acetyl acetonate. The activating agent may be a Grignard reagent, a metal alkyl, or another organo-metallic compound, particularly aluminium diethyl ethoxide or aluminium triethyl. A diluent may be present. Examples are directed to the dimerization of propylene.

Abstract: 1,225,252. Digital data processor. PLESSEY CO. Ltd. 7 March, 1968 [14 April, 1967], No. 17361/67. Heading G4A. Digital data processor communicating over a single channel with a plurality of external data handling devices has a memory arranged to store data transfer control words at locations representative of a device producing a demand condition, the control words including an address specifying the address in memory to be used for data involved in the transfer and an instruction codecontrolling the data processor in the execution of the transfer. A peripheral device requiring access to a store initiates an ADT demand signal ADTD which passes to a Buffer ADTDB. The Control logic PADTC is conditioned to inhibit the central processor unit at the completion of the current instruction and a demand accept signal ADS is returned to remove the original demand and cause the transfer of parameters and direction signals to be sent to the PADTC. A first set of locations in the store are reserved for the peripheral devices with address corresponding to the identification numbers of the devices, e.g. store 1 is reserved for device No. 1, 1, store 10 for device 10. Five instructions can be held in these locations, one controlling block transfer to or from the store, one controlling single transfer operations, one having an iteration count and creating a high priority interupt when the count reaches 0, a fourth specifying a store location into which or from which data is to be transferred and a fifth allowing a bit to be ORed into a data word stored at a specified address. The micro-command signals generated by the instructions are given. The peripherals communicate via an ADT input/output system which can be tiered, the tiers having the same equipment and allowing the connection of an expandible number of peripherals (Fig. 3, not shown). As described, an ADTI/P in level three communicates with eight ADTI/P in level two, each of which communicates with eight ADTI/P in level one, each of which communicates with eight peripheral units. Each tier produces a three-bit address, addresses from each level being attached together to produce a nine-bit address applied to the processor. Fig. 6 (not shown) illustrates gates providing demand sorting, providing an order of priority and supplying the peripheral unit number to an address generator.

Abstract: 1,226,495. Preparation of vinyl-containing polysiloxanes for cure to elastomers. WACKERCHEMIE G.m.b.H. 17 March, 1969 [18 March, 1968], No. 13872/69. Heading C3T. An organopolysiloxane elastomer is prepared by cross-linking a copolymer which has been prepared by equilibration of a dimethylpolysiloxane with a copolymer comprising 75-90 mol. per cent dimethylsiloxane units and 25-10 mol. per cent methylvinylsiloxane units. The dimethylpolysiloxane may contain up to 5 mol. per cent of units other than dimethylsiloxane units, and further other units may be introduced into the final copolymer by incorporating other organopolysiloxanes in the equilibration mixture. Conventional equilibration catalysts and solvents, and curing and cross-linking agents and fillers and other additives are listed. In examples, a dimethylpolysiloxane of 287 cSt./25‹ C. or a mixture thereof with an 80/20 (mol. per cent) dimethylsiloxane/methylphenylsiloxane copolymer is equilibrated with an 80/20 dimethylsiloxane / methylvinylsiloxane copolymer (prepared by cohydrolysis) in the presence of a phosphorus nitrile chloride and optionally a trimethylsiloxy-terminated dimethylpolysiloxane or a sym-tetramethyldivinyldisiloxane, to give products of molecular weight 600,000 to 2 million having one vinyl group per 500- 1000.Si atoms; these products are compounded with 7 p.b.w. hydroxy-terminated methylphenylpolysiloxane, 40 p.b.w. of pyrogenic silica and 1À2 p.b.w. of a bis-2: 4-dichlorobenzoyl peroxide/dimethylpolysiloxane paste per 100 p.b.w. of product, and cured to give elastomers.

Abstract: 1,227,092. Sulphur trioxide; sulphuric acid. RALPH M. PARSONS CO. 20 March, 1969 [21 March, 1968], No. 14667/69. Heading C1A. In the production of sulphur trioxide wherein the SO2 content of a gas stream is converted to S0 3  in a series of catalytic steps with an intermediate sulphur trioxide extraction step, the feed stream 14 to the converter 18 which is at a temperature higher than that required by the first catalytic step is cooled to the required catalytic conversion temperature by indirect heat exchange with the cool gas stream 22 returning to the converter from the intermediate S0 3  extraction step in absorber 20, and this return stream also serves to cool by indirect heat exchange the product stream 28 passing to a catalytic conversion step subsequent to the first but before the intermediate absorption step, but is not used to cool the product stream emanating from the catalytic step immediately before the absorption step, the said return stream thereby being heated to a suitable temperature for catalytic conversion in a further step. A plurality of catalytic conversion steps may be accomplished between the said first step and prior to the intermediate SO 3  extraction step and the product stream passing to each catalytic conversion step subsequent to the first and prior to the intermediate extraction step is cooled by indirect heat exchange with the return gas stream. Sulphuric acid may be produced by absorbing the SO 3  produced in an aqueous liquor. The SO 3  may be absorbed in sulphuric acid, and the S0 2  absorbed with the SO 3  in this acid may be stripped from it, e.g. using air in tower 60, and recycled via line 16 back to the converter inlet stream. The reaction product from the last catalytic conversion step before the intermediate extraction stage may be cooled by indirect heat exchange, e.g. with water in heat exchanger 39, to a temperature required by the extraction step. As shown in Fig. 1 the return gas stream may be split into two streams 24 and 32 one serving to cool the converter inlet stream 14 and the other cooling the reaction product stream 28. In alternative embodiments (Figs. 2 and 3, not shown) the return gas stream may cool these two gas streams successively either one of them being taken first. The reaction product stream emanating from the final catalytic stage is extracted in a final absorber 48 before the residual gas is passed to the stack.
