Title: Process for improved sulfoxidation products
IPC: C07C303/14
Filed: 1965-10-27
Abstract: Sulphonic acids are obtained by continuously supplying a substantially straight-chain, C10-C30, saturated hydrocarbon feed containing less than 10 moles per cent of molecules containing tertiary carbon atoms and less than 10 moles per cent of mono-olefins, to a first-stage, stirred reactor, continuously supplying SO2 and oxygen in a molar ratio of at least 2:1 to the reactor, reacting the mixture at 90 DEG  to 150 DEG  F., and 0 to 1000 p.s.i.g. to a hydrocarbon conversion of at least 1%, the reaction being initiated either by high-energy radiation or chemical initiators supplied to the first-stage reactor or by persulphonic acids introduced thereto from another reactor, continuously withdrawing from the first-stage reactor a portion of the reaction mixture and supplying it to a second-stage, stirred reactor, supplying oxygen and SO2 to the second-stage reactor, reacting the mixture at 90-150 DEG  F., and 0 to 1000 p.s.i.g., continuously withdrawing a portion of the reaction mixture from the second-stage reactor, after a residence time in both reactors to obtain conversions to sulphonic acids of 2-9%, quenching and reducing the withdrawn mixture with an aqueous reducing agent and recovering sulphonic acid from the said quenched mixture.  The process may be carried out under substantially anhydrous conditions, e.g. with less than 500 p.p.m. of water being present in the reaction mixture.  The hydrocarbon feed may be fed directly to the first-stage reactor or some of it or a different feed of the same type may be passed through a separate small seed reactor, to which oxygen and SO2 and either gamma radiation or a chemical initiator are continuously fed, to obtain a vigorously reacting sulphoxidation mixture containing persulphonic acids which kindle the sulphoxidation reaction and react with and remove impurities.  In the former case radiation or chemical initiation is supplied directly to the first-stage reactor. Specified sources of radiation are X-ray and beta-ray machines, waste materials from nuclear reactors, e.g. spent fuel elements or portions thereof, neutron reactors and artificially produced isotopes, e.g. cobalt 60, and specified chemical initiators are diacyl peroxides, e.g. lauroyl peroxides and benzoyl peroxide, azo compounds, e.g. azo bis isobutyronitrile, peroxides, e.g. t.-butyl perbenzoate, and leat tetra-acetate.  In addition to the reactants specified, liquid or gaseous diluents, e.g. chloroform, carbon tetrachloride and/or nitrogen may also be used.  The quenching process may be effected by SO2 and water and the quenched product is separated into an aqueous phase from which the sulphonic acids are recovered, e.g. by neutralization, deoiling, desalting, evaporating, drying &c., and an oil phase which after drying is recycled to the first-stage reactor.

A priority circuit 22 grants access to a common data and address in-bus 14 by one of requesting I10 channels 11, 12, the data and address supplied by the selected channel being loaded in a buffer dedicated to that channel. Each channel is allocated a group of buffers consisting of 2 sections in the channel-in buffers and 2 sections in the channel-out buffers. Storage priority circuit 32 (detailed in Fig. 5) forms buffer queues for the different storage areas in order of channel priority, the highest priority requesting channel being granted access to the required storage area when that area becomes available. If data transfer is requested from storage to channel, data is transferred to a buffer-out 34 which is unloaded in the same sequence that requests from a particular channel were received, and access to the bus-out 16 is controlled by a priority circuit 36. Each channel places a first request in one of the sections of the associated buffer group, the next request in the other section of that buffer group, and subsequent requests in whichever section first becomes non- busy.

Abstract: 1534702 Anchoring plugs in bores A FISCHER 7 Nov 1975 [14 Nov 1974 26 May 1975 6 June 1975 7 June 1975 14 June 1975 21 June 1975] 46198/75 Heading F2H A method of anchoring a plug 1 in bore 16 comprises positioning the plug 'substantially centrally within the bore by means of a bush 6 having at least one air vent 17 which substantially closes the gap between the plug and the mouth of the bore, and introducing a fixing agent 9 into space 5 via a hole in the bush or plug. The insertion end of the plug may be squashed flat and bent in the manner of a barb. A thread 3 for a screw or anchor bolt may be tapped in the bore at the outer end of the plug. The bush may be provided with a flange 8 and a hole 11 through which fixing agent may be injected into the hollow space. A funnel 12 may be formed around the hole 11. After the fixing agent has set, the hole may be stopped by stopper 14, which is knocked in grooves 17, see Figs. 1 and 2, may be formed beneath flange 8 and on the outer sleeve surface, and one of the grooves may be associated with a part-tubular extension 18, so that when the bore 16 is filled with fixing agent, air may be displaced via the channels formed by the grooves and extension. In a modification (Figs. 3, 4, not shown) the hole 11 in the bush is closed by a rotatable disc segment having a cylindrical stub which fits into the bore of the plug. Instead of introducing the fixing agent through a hole in the bush, it may be injected into the hollow space surrounding the plug via an aperture in the insertion end of the plug (Figs. 5-12, not shown). To prevent the fixing agent from completely filling the bore of the plug, a stopper having a filling hole provided with a valve closure (Fig. 5, not shown) may be located therein; or an appropriate nozzle may be mounted on the nozzle of the injection device for insertion in the aperture in the insertion end of the plug (Fig. 6, not shown). The bush may be provided with a tapering sealing lip to seal the mouth of the bore in the masonry in the event that it may have broken away (Figs. 7-12, not shown). After the fixing agent has set, a plastics plug having an external thread matching the internal thread of the plug may be screwed into the plug until a limiting flange thereon meets the end of the plug. The bore of the plastics insert may be provided with longitudinal ribs (Fig. 9, not shown). The plastics insert may also be provided with a longitudinal slit. An annular groove may be formed in the inner surface of the bush so that fixing agent may set therein to form a solid core (Fig. 10, not shown).
