Abstract: 411,863. Boot - making machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., Union Works, Belgrave Road, Leicester.-(United Shoe Machinery Corporation; 140, Federal Street, Boston, U.S.A.) Dec. 10, 1932, No. 35052. [Classes 17 (i) and 89 (iii).] Lasting.-In the making of veldtschoen, the forepart of the upper is conformed to the shape of the last and secured by fastenings driven into the last at opposite sides outside but close to the bottom face of the last. The sole may then be secured to the last and the fastenings bent in a compound curve further to tighten the upper and simultaneously to lie substantially parallel with the out-turned margin of the upper. A pulling-over machine of the kind described in Specification 7005/00 may be used, with modified tack driving means comprising a reciprocating driver bar 36 provided with an arm 45 carrying a pin 46 engaging a slot in an arm 42 pivoted at 43 and carrying a clamp 44 for a driver 37. An upper clamping stop 49, wiper 48, and tack passage 47 are carried by a plate 38 urged towards the work by a spring 41 and guided by slots engaging bolts 39, 40 in the usual swinging arm 34. When the upper has been pulled over, arms 31 carrying pads 32, are swung to contact with the shoe to support it against the thrust of the drivers, the arms 34 also swinging inwardly and tripping the grippers as usual by contact with their fingers 35. The tacks are then driven into a bevelled surface at the edge of the last bottom. The work may then be transferred to a machine of the kind described in Specification 341,958, a sole being previously secured to the last. Wipers 54 are then forced inwardly and a sole support 52 is raised to bend the tacks in a compound curve to tighten the upper over the last and, at the portions near their heads close to lower surface of the wipers. So that the wipers may not stick to the upper as they are withdrawn their surfaces are highly polished or plated with chromium. The sole may then be stitched to the projecting margin of the upper in the machine described in Specification 392,580. Specifications 7005/00, [Class 17], and 341,958 also are referred to.

Patent GB-486322-A (GB)
Title: Process for the manufacture of unsaturated derivatives of compounds of the cyclopentano polyhydro phenanthrene series
Filed: 1936-12-22
Abstract: Unsaturated compounds of the cyclopentanopolyhydrophenanthrene series are prepared by subjecting compounds of the above series which contain a tertiary hydroxyl group and a hydrocarbon substituent on position 17, and a free hydrogen atom adjacent to the tertiary hydroxyl group to a treatment in which water is split off under such relatively mild conditions of temperature and pressure that wandering of the methyl group adjacent the tertiary hydroxyl group is reduced or prevented.  Suitable water elimination treatments which are described are the heating of the starting material in a high vacuum, boiling with acetic acid, and heating with metal salts such as copper sulphate and stannous chloride.  The reaction products in which no wandering of the methyl group has taken place are isolated by fractional vacuum distillation or sublimation, or by fractional crystallization. Suitable starting materials for the process of the present invention may be prepared by the processes described in Specifications 434,390 and 446,501.  The double band produced according to the process of the present invention may be situated between carbon atoms 16 and 17 or 17 and 20.  If the starting materials for the present process contain other hydroxyl groups besides the tertiary hydroxyl group on position 17, it is preferred that such other hydroxyl groups should be protected by esterification or etherification.  The protecting group may be removed after the reaction if desired.  On the other hand reaction products which contain a free hydroxyl group may be esterified or etherified. Starting materials mentioned are 17-methyl-dihydrofollicle hormone, 17-ethyl androstendiol-3 : 17, and 17-isopropyl-androstandiol-3 : 17. In an example: 17-methyl dihydro follicle hormone is boiled with glacial acetic acid under reflux for five hours.  Samples have been furnished under Sect. 2 (5) of (1) the dehydration product of 17-ethyl androstenol-17-one-3 obtained by distillation in a high vacuum; (2) the dehydration product of 17-methyl-androstendiol-3 : 17 obtained by boiling with dilute sulphuric acid; (3) the dehydration product of 17-ethyl-androstendiol-3 : 17 obtained by boiling with a glacial acetic acid solution of zinc chloride.

Title: Improvements relating to slicing machines
IPC: B26D7/06
Filed: 1927-12-30
Abstract: 282,825. Berkel, C. F. M. van. Dec. 30. 1926, [Convention date]. Cutting slices in succession.-The feed-screw of a disc-knife reciprocating table machine is operated by two actuated devices, one of which rotates the screw at the end of the return stroke and the other rotates the screw in the same direction at the beginning of the slicing stroke. As shown in Fig. 2, the feed-screw 3 is journaled in brackets 2 on the carriage 1 and is actuated in succession by pawls 20, 16. A lever 5 is journaled on an extension of the screw 3 and carries a roller 6 running along a cam-guideway 7 which extends longitudinally of the machine to the end of the slicing-stroke. The spring-pressed pawl 20 is pivoted at 21 to the lever 5, and, at the end of the return stroke, the roller 6 is depressed by the curved part of the guide 7, and rotates the lever 5, pawl 20 and the ratchet wheel 18 in the counter-clockwise direction. At the beginning of the slicing-stroke the lever 5 is rotated clockwise and the pawl 20 rides over the ratchet teeth. The toothed segment 8, attached to the lever 5, rotates the pinion 9 clockwise and the pinion 11 is thus rotated counter-clockwise. The pimon 11 carries two strikers 12, 13 which contact with a pin 14 on an arm 15 carrying the spring-pressed pawl 17. The pinion 11 is thus coupled through a lost-motion device to the pawl 17 which thereby imparts the second counterclockwise rotation to the feed-screw 3. The guideway 7 is longitudinally adjustable for slice-thickness regulation by a member 25. Other adjustment means may be provided, e.g. the strikers 12, 13 and the sector 8 may be adjustable. The Specification as open to inspection under Sect. 91 (3) (a) states that the pawl 16 may be adjustable with respect to the pawl 20. This subject-matter does not appear in the Specification as accepted.

Abstract: 761,216. Centrifugal and axial-flow compressors. SULZER FRERES SOC. ANON. Dec. 9, 1954 [Dec. 12, 1953], No. 35723/54. Class 110 (1). A casing for the outflow of gas from a compressor comprises an annular inlet passage 8 through which gas coming from the compressor is introduced tangentially into a toroidal chamber 9, and two discharge passages 2 leading from the toroidal chamber through which the gas flows away in two separate streams rotating helically in opposite directions as indicated by the arrows 10, 11. The casing is shown with part, including one of the discharge passages 2, cut away; each half of the casing on either side of the plane I-I is a mirror image of the other half. The gas discharged by an axial-flow compressor divides at the arrow 5 and also at the arrow 7 to form two pairs of helical streams flowing towards opposite discharge passages 2 and uniting to form the two oppositely rotating helical streams indicated by the arrows 10, 11. Passage 8 is separated from the toroidal chamber 9 by a wall 12 and increases in crosssectional area from inlet to outlet to act as a diffuser; it deflects the gas from its original axial direction through 150-180 degrees. The maximum cross-sectional dimension AB of the toroidal chamber 9 should not exceed 1.5 times the minimum cross-sectional dimension CD; the smallest radius of curvature r should be at least 25 per cent of the dimension CD. In the case of a radial-flow compressor, the gas may enter the chamber 9 tangentially at the position indicated at B, and the rotation may be in the directions of the arrows 10, 11 or in the opposite directions.

Abstract: 826,997. Packaging-machines. MEAD PACKAGING, Inc. [formerly MEAD ATLANTIC PAPER CO], Nov. 22, 1956 [June. 15, 1956], No. 35802/56. Class 94(1). A machine to facilitate hand wrapping of groups of cans in wrappers which are laid on top of a group, folded down each side and then overlapped and secured beneath includes guides to support the group for initial wrapping and to direct the package to a position where tongue and slot means are automatically engaged to join the overlapped portions. The machine is fully adjustable and may be adapted for groups of one or two rows. Cans C are placed on a guideway formed by rails 104, 105, Figs. 3, 9, and a blank W, which may be substantially as described in Specification 790,815, from a magazine 103, is placed on the group arid folded down the sides of the cans, round the outside of the rails 105, and overlapped beneath the rail 104, this folding occurring with the cans on the more unsupported section 101 of the rails. Parts 108, 109 on the rails act as a positioning gauge for the wrapper and cans. The package is pushed forward manually onto further rails 106, Fig. 1, over a pivoted stop 119, Fig. 14 (not shown), which rises behind the package, the package then being pulled back against it for correct positioning above the locking devices. Prior to locking, the wrapper is tightened across the package base by fingers 143, Figs. 1, 17, which enter apertures 26, 28 in the overlapped portions 14, 16, Figs. 4, 7 (not shown) and apply tension to them. The fingers are mounted on frames formed by rods 160 extending longitudinally of the machine and links 139, the links 139 being mounted for movement to the right as shown in Fig. 24, when levers 132 are pulled downwards by a foot pedal operated crank means 127, 130, 131, Fig. 19. Such movement is obtained by fixed cams 136 and rollers 135, and an initial upward movement of the fingers to cause them to enter the apertures is produced by cam surfaces 141 and rollers 140. When the wrapper is tightened, arms 148, swung upwards by the same foot pedal movement, cause members 151 to push tongues through apertures formed by cut out retaining flaps to secure the wrapper. The tightening and locking means are returned by springs and the package is ejected by entry of the next to be completed. When two rows are packaged, two bottom supporting rails, one having a surface raised above the other may support them so that the chines of opposite cans overlap in the completed package as described in Specification 822,412.
