Abstract: 1473338 Automatic exchange systems STANDARD TELEPHONES & CABLES Ltd 20 March 1975 [18 June 1974] 26931/74 Heading H4K A register selectively controls the insertion of an element into a transmission path at a peripheral circuit by simultaneously supplying markings to a control wire associated with the selected element and to a path established through the switching network between the register and the peripheral circuit. In the embodiment, the peripheral circuits are incoming and outgoing junctors 1JC, 0JC and the elements are attenuation pads, the exchange being a TXE4 exchange, NB Specifications 1,057,218 and 1,165,526. For a tandem call, an incoming junction 1J is coupled via junctor 1JC and the switching network to a register REG, which on recept of digits indicating a tandem call causes a path to be set up to a suitable outgoing junction 0J over which the routing digits are sent on. The register connections to the two junctors 1JC, 0JC are then dropped and the connection switched via an intermediate junctor ThL3. However before the register is dropped a central control unit causes selectors SA, SB to step to mark wires AP, BP or CP, and DP, EP or FP associated with attenuation pads in the junctors 1JC, 0JC. This action causes a repetitive pulse train applied at SP to periodically supply a marking to each of the two selected control wires, and the attenuation pads are then switched in when a pulse supply PS supplies a pulse on the P wires of the register to junctor connections. The pulse supplied to the calling side junctor P wire is also effective to switch through the final path via junctor ThL3 in the usual manner for TXE4. The value of the attenuation pad switched in is determined from the identity of the outgoing junction, e.g. from the routing digits. The peripheral circuits could be line circuits and the elements could be associated with metering equipment.

Patent GB-468025-A (GB)
Title: Process for the manufacture of reduction products derived from dehydroandrosterone
Filed: 1936-10-06
Abstract: Pure dehydroandrosterone is subjected to a process to give a saturated reduction product which comprises the replacement of the hydroxyl group at position -3 by a halogen followed by a reduction treatment, whereupon the halogen atom is reconverted into the hydroxyl group.  The preferred halogenating agent is thionyl chloride, and the preferred method of reduction is a catalytic reduction using a noble metal catalyst such as platinum or palladium. The reduction may be either allowed to proceed to its full extent so that 4 atoms of hydrogen are added to one molecule of the unsaturated halogen ketone with the formation of a saturated halogen alcohol, or the reduction may be stopped when 2 atoms of hydrogen have been taken up with the formation of the corresponding saturated ketone. Additional halogenating agents are hydrochloric acid and also the agents which are mentioned in Houben-Weyl Methods of Organic Chemistry, page 1115.  The replacement of the halogen by hydroxyl may be carried out by causing the halogen to react with salts of carboxylic or sulphonic acids whereupon the esters so formed are hydrolyzed.  The conversion may however take place directly, or other substituents may intermediately be introduced into the reduction product, such as the amino group.  In examples: (1) Thionyl chloride is added to an ether solution of dehydroandrosterone in the presence of precipitated calcium carbonate to give the corresponding unsaturated chlorketone.  This is hydrogenated in alcoholic or glacial acetic acid solution in the presence of a palladium catalyst such as palladium black, palladiumbarium sulphate or palladium-calcium carbonate.  The hydrogenation may be interrupted after two atoms of hydrogen per mol. of chlorketone have been taken up to yield the corresponding saturated chlorketone which can be separated by means of its semi-carbazide, or the hydrogenation can proceed until 4 atoms of hydrogen have been taken up, in which case the corresponding saturated chlor-alcohol is formed.  The chlorketone thus obtained is heated with potassium acetate and the ester saponified with methyl alcoholic potash to give androsterone; (2) Dehydroandrosterone is halogenated with hydrogen chloride in methyl alcoholic solution and the product separated from any unconverted starting material by means of digitonine.  The pure chlorketone so obtained is hydrogenated and converted into the free hydroxy compound as in example (1).
Patent GB-698631-A (GB)
Title: Improvements in or relating to oxo alcohol treatment
IPC: C07C29/74
Filed: 1950-11-07
Abstract: A process for the treatment of an impure alcohol produced by the Oxo process comprises contacting the Oxo alcohol with a copper or cobalt salt.  Many copper salts and cobalt oleate are mentioned as suitable. Some metallic salts may be used in conjunction with another agent, e.g. cuprous sulphate may be employed in the presence of ammonia, cupric chloride and cupric oleate may be used with added air and metallic copper may be used in conjunction with the metallic salt. Water soluble, water-insoluble and oil-soluble salts such as copper salts of fatty acids may be employed.  Air blowing with the salt treatment may be useful.  In some cases the solid treating material may be employed as a fixed bed and an inert support may be used.  The process may be carried out as a distillation in the presence of the salt or the latter may be dissolved or suspended in the alcohol or in a suitable solvent.  The process may be conducted batchwise or continuously and is preferably carried out under neutral conditions. The alcohol may be washed after the treatment and before distillation. Ordinary or elevated temperatures may be used.  In examples: Crude iso-octyl alcohols prepared by the Oxo process are contacted at room temperature with cuprous chloride, washed with water and fractionated (I); refluxed with cuprous chloride solution, separated and distilled (II); treated with cupric phosphate during distillation (III); crude and finished alcohols are contacted with copper oleate (IV) and a C8 or iso-octyl Oxo alcohol is distilled in the presence of copper oleate (V-VII). The colour of phthalate esters, prepared in contact with stainless steel and sulphur contents of the products are compared with those of the corresponding untreated alcohols.  Olefinic compounds mentioned as starting materials in the oxonation step include aliphatic olefines and diolefines, cyclo-olefines, aromatics with olefinic side chains and oxygenated compounds having double bonds.

Title: Treatment of petroleum oils by contact with water
IPC: C10G31/08
Filed: 1950-11-07
Abstract: <PICT:0705267/III/1> A petroleum gas oil fraction boiling in the range between 400 and 850 DEG F. and contaminated with water-soluble metallic salts is washed with an amount of water (of pH5.0-7.3 and at a temperature of 160-212 DEG F.) corresponding to 10-20 per cent. of the volume of the gas oil fraction and then freed from water. Water-soluble salts which may be removed in this manner include those of iron, sodium, nickel, aluminium, vanadium, silicon, calcium and chromium.  The purified gas oil may be used as a feed stock to a catalytic cracking operation.  In Fig. 1, the gas oil is introduced through line 11, water of the correct pH is introduced through line 12, and the gas oil and water are mixed in mixer 13. The mixture passes to settling zone 15, where an oil phase, a water phase and an emulsion phase separate.  The oil phase is withdrawn through line 16 and passes, either directly or via filter zone 24, to catalytic cracking zone 26.  Filter zone 24 removes the last traces of water and may contain a bed of activated alumina, adsorptive resin for removing anions and cations, or a natural or synthetic zeolite.  The water phase from settling zone 15 is withdrawn through line 18 and may be recycled. The emulsion phase from settling zone 15 is withdrawn through line 17 and passes to separation zone 29 wherein the emulsion is broken (for example electrically or by settling). Water which separates from the broken emulsion is withdrawn through line 30, while the oil phase is withdrawn through line 32.  This oil may join the main oil stream in line 16, either before or after the filter zone 24, or may be discharged through valve 36.

Title: Improvements in washing machines

Abstract: 971,451. Variable-ratio gearing; clutches. M. DELZENNE, and F. DELZENNE. July 10, 1963 [Oct. 31, 1962], No. 27294/63. Headings F2C and F2D. [Also in Division D1] A change-speed arrangement for a rotary drum washing machine comprises a motor driving (via two coaxial V-pulleys 2, 3 and belts 4, 5) V-pulleys 6, 7 which are mounted freely rotatably one on each side of a pulley 12 on a hollow shaft 23, and which can move axially relative to the shaft so that one only is engaged with pulley 12 which is also freely rotatable but is fixed against axial motion and drives the rotary drum by a belt 13 and a pulley. The flanges of pulleys 7, 12 have clutch linings 31, 30, and a plate 18 loosely mounted on shaft 23 has a clutch lining 34 facing pulley 7. The pulleys 6, 7 are interconnected by pins 29, 32 which engage the pulleys, respectively and pass through slots 42 in the hollow shaft 23 and are mounted in a rod 24 which is mounted for axial motion within the shaft 23. The drive is usually held in its low speed (washing) position with pulley 6 driving pulley 12 by means of a spring 40. To change to high speed (spin-drying) a lever 39 is depressed which moves plate 18 so that its clutch lining 34 engages pulley 7. The plate 18 is thus caused to rotate and bring into operation centrifugal devices comprising weights 36 which are thrown outwards causing the devices to pivot about 44 and bring pads 35 into contact with the flange of pulley 7. The drive to plate 18 is now via the pads 35 instead of the clutch lining 34 and the plate 18 is pushed back to its original position. As the centrifugal devices move further they push pulley 7 to the left thus causing the pulley 6 also to move to the left. Thus pulley 6 is disengaged from pulley 12 and pulley 7 is engaged with pulley 12. When the machine is stopped the original position is attained by all the parts. The belt tensions may be adjusted by relative motion between the motor shaft and the shaft 23 and also by the pulley 3 which has a spring-loaded flange 8.
