IPC: C10G27/04
Filed: 1953-07-14
Abstract: A sweetening process comprises sweetening a virgin petroleum fraction with air in the presence of a petroleum fraction containing olefin unsaturates.  The fraction containing unsaturates is one obtained by thermally or catalytically cracking a petroleum fraction.  The virgin fraction may be an extract from solvent extraction of kerosine e.g. with sulphur dioxide, and may be caustic alkali washed.  The air sweetening is preferably conducted in the presence of an accelerator, which may be an oxidation inhibitor such as disec. butyl p phenylene diamine, and is carried out either by blowing with air or by standing with exposure to air.  The olefinic fraction may consist in whole or in part of a sour fraction which readily air sweetens, or a sour virging naphtha which easily sweetens may be added to the kerosine extract.  It is preferred to use betwen 9 and 100 per cent by volume of the olefinic fraction based on the virgin fraction.

Title: Improvements in the electro-deposition of metals
IPC: C25D7/06
Filed: 1944-12-27
Abstract: 573,422. Electroplating strip material. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., CALLENDER-SUCHY DEVELOPMENTS, Ltd., RICHARDSON, A. B. F. G., and SUCHY, C. T. Dec. 27, 1944, No. 19618/43. [Class 41] Strip material, particularly non-conductive material, is given an electrodeposited coating by a process in which the material is passed continuously through a washing and cleaning bath and then through the plating bath in direct contact with positively-driven cathode rollers. Preferably an impregnating bath is inserted in the process before the plating, for rendering the material preliminarily conductive by chemical impregnation of its structure with particles. Fig. 1 shows diagrammatically a process for metallizing textile fabrics or other non-conductive strip materials, which is taken from a reel 1, washed and de-greased at W and given an airdry before passing into the impregnating tank I, where it is treated with, for example, silver cyanide solution. A further air-dry is followed by washing at W<1>, passing through a drying duct 16, and removing surface metal particles by brushes 18. The strip then enters the plating bath E, is given a final washing at W<2> and drying at 19, and is finally coiled on to reel 20. Driving rollers 8, 8a, 8b for the strip are all actuated by suitable belting from a motor, Fig 4 (not shown), which drives the rollers 8b through a pair of change-speed pulleys 27, 29 and belt 28, a further pulley on the axle of 29 driving through belt 20b a pulley 20c on the reel 20. The latter is connected to the shaft 57 of pulley 20c through a friction clutch in order to allow for the slowing up of the reel as filling proceeds, Fig. 10 (not shown). The cathode rollers 30 are all rotated by a belt 32, Fig. 2, passing from a pulley coaxial with 29, over guide pulley 33, support rollers 35a, guide pulley 34 and then over and under the cathode rollers to guide pulley 33a. The rollers 30 are insulatingly carried on axles 30a supported in open slots 40 in angle-irons 41, forming part of an open frame F, the upper members of which rest on the top of the vat and carry angle bars 31b insulatingly supporting the cathode busbar 31. The latter supports the cathode rollers by means of hooks 36 secured by nuts 39 in an insulating plug 37 threaded into a tube 38. A slip ring 47 on an insulating sleeve 48 on shaft 30a is connected by screw 50 to the roller 30, and is engaged by brush 46 supported from an insulating plug 45 in the bottom of tube 38 and connected at 42 to hook 36. A pair of anode plates 52 are supported on rods 54 inserted in appropriate holes 56 in vertical brackets 55 on the angle-irons 41. For thin deposits, some of the cathodes may be bypassed, and in the case of deposits on conductive strips the impregnating step would be omitted. A modified construction of connection to the cathode rollers is also described, using a flexible lead sealed into the roller and making sliding connection to the supply at a point above the electrolyte level.

Filed: 1927-07-25
Abstract: 275,601. Krupp Akt.-Ges. Friedrich- Alfred-H³tte, F. Aug. 6, 1926, [Convention date]. Blast and cupola furnaces.-In a method of operating shaft, and especially blast furnaces, involving the utilization in the furnaces of a portion of the waste gases, the blast is delivered at a higher temperature than usual in order to supply sufficient heat to heat up the waste gas to furnace temperature, whilst the coke charge is correspondingly reduced, and changes in the thermal and chemical equilibrium of the process are compensated for by varying the quantity of waste gas supplied. Loss of working temperature may be compensated for by heating the waste gas or by adding oxygen. As an additional means of control coal dust is supplied, with waste gas close above the tuyeres. Waste gas alone may be introduced above tuyere level to act as a local cooling agent.

Filed: 1959-06-10
Abstract: 876,824. Magnetic recording &c. heads. SIEMENS & HALSKE A.G. June 10, 1959 [June 10, 1958], No. 19829/59. Class 40 (2). [Also in Group XXXVI] A magnetic head is formed by assembling two ferrite blocks 1, 2 about a Hall plate 4, typically of indium arsenide, deposited as a vapour film. Vapour-deposited metallic foil connections 5 for the Hall plate may emerge to the exterior of the head for convenient contact. The number of connections required may be reduced, Figs. 3, 3a, by sharing contacts between the polarizing current and the Hall output e.m.f. A very close magnetic gap is achieved by micro-polishing with iron carbonyl, the interstices 18 unavoidable with normal grinding of suitable ferrites being filled by the carbonyl. To increase sensitivity, the Hall plate may have a wedge form 20, maintaining a narrow transducing gap at the surface 21. A combined head, Fig. 7, records normally at the gap 30, by means of the coil 28, a Hall plate being used for playback at the gap 32. The polarizing current may be used additionally to provide a magnetic polarizing field as in Fig. 8, adjustment of a number of members such as conductor loop 36 enabling the sensitivity of the elements of a multi-track head, Figs. 6, 9 (not shown), to be equalized.

Abstract: 622,829. Vehicle suspensions; springs &c. LOCHER, H. NEIDHART-. July 3, 1946, No. 19910. Convention date, Aug. 28, 1945. [Classes 108 (ii) and 108 (iii)] [Also in Group XXXIV] in means for resiliently mounting one part upon another wherein one part is resiliently and flexibly attached to the other by means of helical springs which are substantially horizontal when the parts are in central position, the springs are each provided with pointed end portions which engage sockets provided one on each of the parts. Two half-axles 7, Fig. 2, pivotally-mounted on the vehicle frame each carry two discs 3 connected to carrier plates 11 by tension springs 4. If a continuous axle is used, the inner plates 3 and the corresponding springs are dispensed with. In Fig. 3, the central flange 15 of a double wheel rim 12 is connected by springs 4 to discs 16 secured to the axle 1 on either side of the flange. For a single-tyred wheel, the rim has two flanges connected by springs to a single disc attached to the axle. In a modified wheel construction, Fig. 7, a flanged wheel-rim 19 has inwardpointing projections 20, 23 formed alternately on each side. A hub attached to the axle 1 has corresponding projections 21, 22, which are connected by springs 4 to the corresponding axially-remote spokes on the rim. Stops limiting the tilting of the rim may be provided. To secure it to a wheel part, each spring end is formed into a hook to engage a cup which may be formed in a tapered plug inserted into a hole in the wheel part. The hook may be made as a separate part and screwed to the spring end. The hooks may be held in place on the wheel part 16, Fig. 13, by caps 33, of which a set may be replaced by a ring of suitable section; or by passing them, before engagement with the cups, through slots cut in the wheel part, the long axis of each slot being at right angles to the normal direction of the plane of the corresponding hook. Compression springs may replace the tension springs. The Specification as open to inspection under Sect. 91 comprises also a construction in which the springs terminate in balls instead of in points. This subject-matter does not appear in the Specification as accepted.

Filed: 1975-05-13
Abstract: 1501216 Time switches ETABS CARPANO & PONS 13 May 1975 [14 May 1974] 20182/75 Heading H1N A programmer for washing-machines, for example, comprises a time-driven rotatable programming means, such as a cam block 1, a selector cam 7 coupled for rotation with the main programme cam 1 by lugs 4 and 6 which allow relative axial movement, and a control element 12 manually rotatable by knob 35 to a desired programme starting position. The angular setting of control element 12 causes ramps 22, 23 thereon to leave arcuate slots (27, 28, Fig. 3, not shown) in selector cam 7, thereby depressing cam 7 axially against spring 9. This allows lever 51 to be moved by spring 49 and close contacts 57 which may be wired to produce rapid advance of cam block 1 and with it selector cam 7. When the arcuate slots (27, 28) in cam 7 align with the ramps 22, 23 the cam 7 is restored axially by spring 9 as soon as follower portion 53 of lever 51 drops into a recess 39, 40, 50, or 41 corresponding to the start of the selected programme, and the respective incline 60, 61, 62 or 63 will cam lever 51 to open contacts 57 and stop the rapid advance. Momentum ensures that lever 51 is cammed to close contacts 56 which may be wired to provide normal programming timed drive. Follower 53 then follows the periphery 38 of cam 7 until it drops to level 44, 45 or 46 of a succeeding recess, corresponding to the end of the set programme, and lever 51 reverts to the OFF condition shown. Recess 50 is not stepped like recesses 39, 40 and 41 but is bridged by periphery 38 such that the programme starting at notch 40 continues till follower 53 enters notch 41; the incline 62 of recess 50 can, however, act as a starting cam and, if chosen, then only the latter portion of this programme is performed. In an alternative embodiment (Fig. 10, not shown) the ramps on the control element (72) co-operate with slots (76) in an auxiliary member (77) to produce axial movement of the control element (72) and with it the selector cam (75), the auxiliary member being driven in unison with cam block 1 but not axially slidable. In a further embodiment (Fig. 11, not shown) the selector cam (81) and main cam block 1 are on an offset axis to that of the control element (82) and a twoarmed lever (89) urges selector cam (81) axially in response to axial movement of the control element (82). Instead of contacts 56 and 57 the lever 51 may actuate a gear change giving normal and rapid drives respectively.
