Abstract: 1495928 Treatment of sulphur containing scrub liquors PEABODY HOLMES Ltd 2 Dec 1974 [25 Oct 1973 29 Jan 1974 16 July 1974] 49703/73 04094/74 and 31380/74 Heading C1A Effluent aqueous alkali liquor containing sulphur compounds obtained in the removal of sulphur compounds contained in a gas stream by scrubbing with an aqueous alkali wash liquor is thermally treated in a combustion chamber under a reducing atmosphere to produce a gaseous combustion product comprising hydrogen sulphide having finely divided particulate matter entrained therein which is quenched by passing through a scrubber to allow the particulate matter to pass into aqueous solution and form an alkali liquor suitable for recycle to the gas scrubbing circuit; the effluent liquor being concentrated prior to the thermal treatment by direct contact with the combustion product. The process is described as being used to treat the waste liquor obtained in a process for the removal of H 2 S and HCN from a gaseous medium in which process the H 2 S is oxidized in the scrubbing liquor to sulphur and the hydrogen cyanide is removed from the gas stream by reaction with a polysulphide in an aqueous alkali liquor to form a thiocyanate the solution then being treated as described above to form an aqueous alkali solution which is made up with polysulphide before being re-used in the gas scrubbing step. The evaporation, combustion and thermal treatment may be carried out in the same reaction vessel, the combustion products and evaporated vapour being combined and passed together into the scrubber.

Abstract: 1,069,513. Conveyers. A. C. COSSOR Ltd. Nov. 26, 1964 [Dec. 20, 1963], No. 50471/63. Heading B8A. [Also in Division G4] The identity of a station is signalled by connecting a rectifier or a combination of rectifiers across wires. A conveyer in a coal mine can be stopped from any one of a number of stations along its length by pressing a switch thereat which breaks a first circuit to stop the conveyer and also connects diodes across a set of wires in an arrangement characteristic of the station. A.C. applied to the set then passes along each of three of the wires only during positive or negative half-cycles or neither and this combination of currents is detected at a control station by circuits comprising oppositely-poled diodes connected in parallel to each of the three wires (Fig. 2, not shown). Each of these diodes is in series with a transformer primary. The transformer secondaries feed AND gates directly and through NOR gates present to recognise the " neither " instances. The AND gates produce a 1-out-of-n selection which is recoded by further AND gates to operate a decimal indicator. Short-circuit alarms are provided.

Title: Magnetic devices
IPC: G11C19/08
Filed: 1973-10-30
Abstract: 1449847 Magnetic storage arrangements WESTERN ELECTRIC CO Inc 30 Oct 1973 [3 Nov 1972] 50500/73 Heading H3B A magnetic bubble is generated in a magnetically biased layer by applying a nucleating pulse to an adjacent conductor of insufficientduration to enable the bubble to develop completely, the growth of the bubble being completed by either a further pulse of propagating intensity and longer duration, or an appropriate orientation of an in-plane rotating. magnetic field used for bubble propagation. Fig. 1 shows a magnetically biased anisotropic layer 11, with bubble support capability, in the form of an epitaxial film of Y 1  Gd 1  Tm 1  Ga 0.8  Fe 4.2  O 12 , for example. Bubble propagation is effected by the combination of a rotating in plane magnetic field and magnetically soft T and I bars, while bubble generation is. effected by the combination of a magnetically soft dot. 16 and a hairpin conductor 17. To generate a bubble domain, a short duration and high intensity nucleating pulse is applied to conductor 17 from a source 19 which causes development of an unstable bubble domain 31, Fig. 3, extending only partially through the-magnetic layer 11 and delimited by an internal domain wall 32. This pulse is immediately followed by a longer duration and lower intensity propagating pulse which extends the bubble to stable size by lateral expansion until the internal domain wall 32 reaches the layer surface. The same effect is obtained by using the rotating inplane magnetic field instead of the second pulse, Fig. 5, the hairpin conductor being partially overlaid by an arcuate strip of magnetically soft material 50. Protrusions S1, S2, S3 from the arcuate strip are so aligned as to avoid cancellation of the rotating field effect for any given in-plane orientation. The two-pulse arrangement may be applied to a bubble domain storage matrix, Fig. 6 (not shown), the high intensity and short duration nucleating pulse being applied to a selected row conductor and the immediately following lower intensity and longer duration propagating pulse being applied to a selected row conductor.
