Title: Improvements in and relating to the preparation of optically active esters of isopropylidenepenicillamine and of penicillamine
IPC: C07D277/06
Filed: 1945-07-30
Abstract: Optically active isopropylidenepenicillamine esters are produced by the hydrolysis and esterification of N-formylisopropylidene penicillamine simultaneously by the action of anhydrous hydrogen chloride in an anhydrous alcohol or successively by treating with a diazohydrocarbon, e.g. diazomethane, and the corresponding alcoholic hydrogen chloride, e.g. hydrogen chloride in methyl alcohol.  The dextro compounds are of interest in the preparation of penicillin - like substances.  a  - Isopropylidine - penicillamine methyl ester is obtained in examples by (1) treatment with dry hydrogen chloride in anhydrous methyl alcohol; (2) esterification with diazomethane followed by hydrolysis with dry hydrogen chloride in dry methyl alcohol.  The optically active penicillamine ester is obtained from the ester hydrochloride produced in example (1) above by treatment with mercuric chloride or alternatively by boiling with water and treatment with alkali.  Specifications 585,250 and 585,413 are referred to.

Abstract: 1307422 Continuous casting GENERAL MOTORS CORP 2 3  April 1970 [26 May 1969 (2)] 19482/70 Heading B3F Low-carbon ferrous metals, and cobalt-based and nickel-based alloys are continuously cast in an open-ended mould 12 attached to a melt reservoir (not shown) by a plug 18 at the mould inlet end. The reservoir may be heated. In operation, three zones are formed within the mould, the first zone comprising a nozzle 32 of boron nitride backed up by a zirconia ring 34, in which zone the melt is completely liquid. A second zone 36, of a higher heat transfer characteristic than the first zone, is of beryllium-copper and is water-cooled. In the second zone, a thin solid skin is formed about the melt. The third zone 38 in which solidification of the melt is completed is water-cooled, 52, and graphitelined, 40. In the second zone 36 the mould is tapered towards the up-stream end of the mould to prevent the thin solid skin tearing, whilst the third zone 38 tapers non-uniformly towards the downstream end of the mould to adapt the contraction of the casting upon cooling. The casting is withdrawn incrementally in lengths equal to that of the second zone.

Title: Improvements in and relating to tobacco feeding mechanisms for cigarette making machines
IPC: A24C5/39
Filed: 1936-07-14
Abstract: 478,310. Cigarette-making &c. machines. AMERICAN MACHINE & FOUNDRY CO. July 14, 1936, No. 19518. Convention date, Sept. 7, 1935. [Class 130] [Also in Group XXX] In a tobacco-feeding mechanism for continuous-rod cigarette-making machines, in which tobacco is showered from a feed drum 12 by a picker roll 14 upon a wide flat conveying member 15 to form a sheet or layer and conveyed thereby in a direction transverse to the cigarette rod, a vibrating device is provided for imparting upward and downward vibratory movements to the member 15 at a frequency such as to render uniform the layer of tobacco conveyed thereby. As shown, the member 15 is supported by a bracket 16 connected to a vibrating device of the kind comprising a centre clamp 17, Fig. 2, secured to the middle of a group of vibrator bars 21 clamped at their ends in a fixed frame 22. An armature 20 carried by the clamp 17 is vibrated by an electromagnet 18 supported by the frame 22 and supplied with an alternating current or with a direct current superposed on an alternating current. The vibrations are imparted at an angle to the member 15, so that the tobacco travels upwards to the delivery end, at which it is showered into the shoot 27 on to a cigarette-paper web P. In modifications, the upper run of a conveyer belt travels over the member 15, which may engage the belt directly or by means of crossbars. In a further form, the upper rim of a conveyer belt is vibrated by mechanical means consisting of one or more polygonal cross-bars engaging the underside of the belt and rotated by sprocket gearing. The Specification as open to inspection under Sect. 91 mentions the application of the invention to conveyers for scrap tobacco in cigar-making machines, and conveyers for other disintegrated material. This subjectmatter does not appear in the Specification as accepted.

Abstract: 180,593. Taylor, A. July 25, 1921. Cutting-appliances.-The invention relates to the provision of a guide or distance-piece on manually-operated splicing-knives as used in preparing the splicing edges on coverings for rollers, such as are employed for example in textile machinery. A bar 1 has a groove 2 cut in one side to accommodate the blade 3 of the splicing- knife, which is held in position by set-screws 4. The opposite side of the bar is shaped with its surface inclined to that of the grooved side, and against this shaped side is clamped a guide-plate 5, held in position by screws 7 which pass through slots 6 in the plate, thus making it capable of adjustment. The angle of bevel of the splicing- edge is thus maintained for any number of cuts.

Title: A method of treating nickel-chromium-containing iron ores
IPC: C22B23/02
Filed: 1960-06-08
Abstract: Iron, nickel and chromium values are recovered from ores containing them, e.g. laterite, by subjecting the ore to a reducing roast, extracting the nickel with dilute sulphurous acid containing 0.5-3% SO2, followed after an optional vacuum distillation to remove some SO2 by blowing air through the solution at 70-100 DEG  C. thereby oxidizing the ferric sulphite to basic ferric sulphate which is precipitated and removed.  The solution before or after basic ferric sulphate removal may be further treated with gaseous oxygen at high temperature and pressure, e.g. a total pressure of 20 kg/cm.2, oxygen partial pressure of 5 kg/cm.2 and a temperature of 210 DEG  C.  The basic ferric sulphate may be calcined to drive off SO2 which may be recovered or recycled, and to form magnetite.  This may be mixed with 20% soda ash and 10% lime, pelletted and roasted at 1000 DEG  C. and the chromium extracted with warm water. If the basic ferric sulphate is subjected with the solution to the high temperature and pressure oxygenation, hydrated ferric oxide is formed and subsequently separated.

Abstract: 471,008. Deep-well pumps. PATTERSON, E. W. July 22, 1936, No. 20344. [Class 102 (i)] [Also in Group XXVI] In a beam-operated deep-well pump the beam 24 is connected at one end to the pump rods by a flexible connection 26 and at the other end is pivoted on a spindle 19 supported by beams 17. The latter at their lower ends carry a spindle 18, which is pivoted in a beam 13. The beams 17 are normally secured in the vertical position by tie-rods 20, but can be swung to the position shown in dotted lines, in order to leave the well-head clear. The beam 24 is oscillated by connecting-rods 45 from gear-wheels 40 on a spindle 41, which is carried by a bearing on the beam 13. The gear-wheels 40 are driven from an electric motor 28 through a belt 37, reduction gearing 36 and chains 44. The load on the beam 24 is balanced by air pressure in a cylinder 51, which is supplied with compressed air from a reservoir 68 through a pipe 69 and the hollow piston-rod 60 of the piston 59. The cylinder is pivoted to the beam while the piston-rod is attached to a cross-head 71 having trunnions supported in bearings on the bed-plate. A constant pressure is maintained in the reservoir 68 by a motor-driven compressor 78. The skirt of the piston has an internal groove 64 from which lubricant, picked up from an annular space 57 in the cylinder, passes through radial holes to a groove on the exterior of the piston.
