Abstract: 926,626. Moulding and attaching soles. BRITISH UNITED SHOE MACHINERY CO. Ltd. Sept. 10, 1959 [June 13, 1958], No. 18914/58. Class 17 (2). In the manufacture of a shoe wherein a last with a lasted upper thereon is positioned against a mould and mouldable material injected to form the sole and attach it to the upper, the inwardly facing edge of the lasting margin is covered by a sheet or continuous film of material to prevent the mouldable material from flowing between the shoe bottom and the lasting margin. The film may be applied by spraying, by adhesive, or by activation of the film itself, and may extend over the whole of the shoe bottom or may finish short of the feather line. The material forms a good bond between the shoe bottom and the sole, preferably the sole is of polyvinyl chloride polymer and the film a mixture of nitrile rubber and vinyl resin in a solvent. The sheet material may comprise a self-supporting homogeneous film, or a web, e.g. of bonded fibre fabric, impregnated with filmforming material as above, and the sole formed of polyamyl chloride polymer. It may extend beyond the shoe, the excess being torn off from the moulded sole, may be precut so that it lies within the periphery of the shoe and allows direct contact between the sole and part of the upper margin, or may be used in strip form. The upper may be lasted in conventional manner, e.g. by tack lasting to an insole, or may be string lasted. When a bottom filler is used, the film extends over the edge of the filler as well as the edge of the upper. Specifications 874,887 and 876,517 are referred to.

Title: Improvements in spool winding machines
IPC: B65H54/28
Filed: 1922-07-12
Abstract: 183,132. Tober, C. July 14, 1921, [Convention date]. Winding-machines; thread guides.- Relates to thread-winding machines of the kind having traverse-mechanism comprising discs provided with projecting pins or lugs arranged to act alternately on the thread, a thread guide being arranged between the spool and the discs. A vertical spool spindle 12, Figs. 1 and 3. is driven by a belt 20, and the rotating pin-discs 3, 5 are mounted on a pivoted frame 17 the position of which is determined by a thread guide 10 bearing on the spool 11. The discs 3, 5 are driven from a worm 25 on the spindle 12, the worm-wheel 26 being shaped to permit swinging of the frame 17. The guide 10, instead of bearing against the spool 11, may be maintained at a constant distance therefrom by means of a roller 37, Fig. 5. In a modified arrangement, Fig. 6. the spindle 12 is disposed horizontally, and the frame 17 is pivoted concentrically with the shaft 24 of a worm 25 arranged to drive the discs 3, 5. The pins on the discs 3. 5 may act indirectly on the thread, and the discs may both rotate in the same direction, the lower part of one disc and the upper part of the other disc acting alternately. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also the following modifications. The discs 3. 5 may be of different sizes and may have different circumferential speeds. In an arrangement for forming conical yarn masses, one disc has three short pins 3<b>, Fig. 22 (Cancelled) and the other disc 5 has three long projections 5<b> so arranged that the thread is first engaged by parts of the projections moving considerably slower than the tips of the projections. Three pin discs 3. 41, 5, Fig. 23 (Cancelled) may be used, the thread being moved from left to right by the discs 5, 41 and from right to left by the disc 3. The disc 5 carries the thread to a point 42 on the thread-guide 10, and the thread is then carried from the point 42 to the right-hand end of the yarn mass by the disc 41. Ir. some cases the thread-guiding pins, instead of acting directly upon the thread, act on a notched sliding or pivoted thread guide; in one such arrangement, a notched thread-guide 47, Fig. 29, (Cancelled), is pivoted on an axis 50 inclined to the common axis of the discs 3, 5, the parts being so arranged that as a pin on the disc 5 turns the guide 47, the latter gradually moves out of the path of this pin and into the path of a pin on the oppositely-rotating disc 3. This subject-matter does not appear in the Specification as accepted.

Title: Machine for grinding the inner surfaces of cylinders, or the like
IPC: B24B5/06
Filed: 1932-07-07
Abstract: 386,885. Grinding internal surfaces. JUNG, K., 48, K÷penickerstrasse, Berlin. July 7, 1932, No. 19219. Convention date, Nov. 21, 1931. [Class 60.] Relates to machines for grinding the interior of cylinders and the like, of the type in which the work is rotated and the grinding tool is carried on a swinging arm, and consists in a construction in which the tool holder is laterally traversed on a slide for coarse adjustment and is adjusted for fine adjustment by the swinging movement. As shown, the work 4 is supported in a chuck 3 mounted in a spindle box 2, carried on a slide 44, the spindle box being capable of being rotated about a vertical axis 45 for cone grinding. The tool 5 is mounted on a spindle 6, the bearings of which are mounted on an arm 15 pivoted on a shaft 16 and having a projection 35, to which is articulated a link 34, connected to an arm 33. The arm 33 is fixed to a shaft 32, which also carries an arm 31, shaped as shown, and serving both as a follower for a cam 30 and to raise a rod 36, which engages and frees driving gear for the cam. The cam is driven from bevel gears 29, which receive motion either from a hand-wheel 28, shaft 27, and bevel gearing 26, or from a constantly rotating shaft s driven by an electric or hydraulic motor. A stop 42 determines the position of the tool at the completion of the grinding operation, when, as shown, the follower 31 is about to drop down the step of the cam 30. When this latter action occurs the gear disengaging device 36 drops to stop the rotation of the gear 29 and thereby also the cam 30. At this instant also the swinging arm is pulled by a spring 24 into position against a stop 23, which determines the position of the swing at the commencement of an operation. The machine works as follows: The wheel 28 is rotated by hand and the cam 30 operated to raise the follower and the rod 36 for engaging the driving gear, the cam having a steep pitch corresponding to this part of the motion. When the gear is engaged the cam is slowly and automatically rotated until the step in the cam is reached, whereupon the disengaging device drops. The shaft 16 is eccentrically mounted for purposes of adjustment. The coarse adjustment of the feed is obtained by means of a laterally traversable slide 17 on which the swing is mounted.

Title: Improvements in or relating to separation of gamma benzene hexachloride
IPC: C07C17/38
Filed: 1952-07-30
Abstract: Benzene hexachloride containing above 96 per cent of the gamma isomer is obtained by extracting the crude product of additive chlorination of benzene with an amount of cold methanol not less than half the weight of the isomer mixture, but such as to leave a substantial part of the mixture undissolved, concentrating the extract by removing 50 to 75 per cent of the methanol, cooling to 0 DEG  to 30 DEG  C. to crystallize a gamma fraction containing 80 to 90 per cent of the desired isomer, dissolving this fraction in at least 3 times, preferably 3 to 5 times, its weight of methanol, concentrating to give a methanol/benzene hexachloride ratio of between 1.25 : 1 and 2.5 : 1, preferably about 1.5 : 1, and cooling to a temperature of 0 DEG  C. to 30 DEG  C. to crystallize a p  second high gamma isomer fraction having a purity of above 96 per cent.  A preferred process giving a product containing over 99 per cent of gamma isomer comprises making the original extract using two parts by weight of methanol to one of benzene hexachloride, concentrating by removing 70 per cent of the methanol, cooling to 15 DEG  C. to crystallize a fraction containing 80 to 85 per cent of gamma isomer, dissolving this fraction in methanol and concentrating as previously described, and finally cooling to 15 DEG  to 30 DEG  C.  Examples are given. Specification 573,693 is referred to.

Title: Improvements in or relating to acrylic acid production
Inventor: BROWN CHRISTOPHER JOHN
IPC: C07C57/07
Filed: 1963-05-16
Abstract: Acrylic acid is recovered from aqueous solutions, especially those obtained by cooling effluent gases with water from the catalytic vapour phase oxidation of propylene, optionally also containing acetic acid, by extraction with ethyl acrylate or acetate, fractionally distilling the separated ester phase to recover the ester fraction overhead as an azeotrope, with substantially all of the water, recovering dry acrylic acid from the base of the distilling column while maintaining sufficient ester in the column to ensure that substantially all the water is removed overhead, e.g. by reflux of ester or condensation of the overhead, phase separation of the ester and return of part of the ester as reflux, the remainder being recycled to the extraction stage.  This is preferably carried out counter current.  The example is described with reference to a flow sheet (not shown) in the Provisional Specification, and employs a rotating disc continuous extractor and a packed distillation column operating at subatmospheric pressure.

Title: Improvements in or relating to devices for producing and controlling the sweeping fire of fire arms such as machine guns
IPC: F41A27/04
Filed: 1920-07-08
Abstract: 147,494. Rauchfuss, K. von, and Jaeschke, E. July 8, 1920. Mounts for machine guns.- Relates to devices whereby the recoil of a machine gun is caused to impart an automatic and self - reversing traverse to the gun. According to the invention, two ratchetwheels are rotated alternately in opposite directions to drive a worm which gears with a toothed training - arc. The ratchet-wheels are mounted on a spindle 36 carried at the lower end of a frame 31 which swings upon pivots 30. The ratchet pawls, one of which 41 is shown, are carried by members pivoted to and laterally adjustable in the frame 31. The frame 31 is movable by a rod 19, operated by a pinion 15 and rack 16, to engage a worm 33, carried by the ratchet-wheel spindle 36, with the toothed arc 69 of a non-traversing slide-bar 75, this movement also causing a rod 8 to actuate the firing-safety catch. The lateral adjustment of the ratchet pawls, effected by a transverselyslidable bar 57 through suitable connexions, brings one of the pawl members beneath one of two vertical spring plungers 4, 5; these plungers are depressed by lugs 2, 3 on a' recoiling member when the gun is fired. The worm 33 is thus rotated and traverses the gun step by step in one direction until the bar 57 engages a limit stop and is moved sideways thereby, to shift the other ratchet pawl into operation and reverse the direction of traverse. Means are provided to regulate the strokes of the ratchet pawls and thus vary the amount of dispersion between successive rounds.
