IPC: A43D21/12
Filed: 1928-08-11
Abstract: 316,025. Gimson Shoe Machinery Co., Ltd., and Bagshaw, C. M. Aug. 11, 1928. Lasting.-The upstanding margin of the upper at the end and sides. of the end of a last is wiped over the last by two wiper-plates that are moved bodily towards each other whilst moving, longitudinally of the shoe. The movement of the plates is effected by a plurality of tack-inserting units, to which converging movements are imparted. The work support 10 is pressed upwards by a spring. The work is engaged by a locator 12, vertically adjustable, and provided with a scale for setting the adjustment. Three tack-inserting units are provided on each side, each mounted on a slide bar 30 carrying a roll 40 engaging a cam slot 41 in a segment plate 42, guided by arcuate ribs 43, 44 engaging between fixed rollers 46 and guide blocks 47. The segment plates are actuated by links 50 from levers 51 having a common fixed pivot 52 and operating links 53 connected to a. slide 54. A cam roll 61 is secured to a slide 58 for reciprocating the slide 54 for the wiping movement. For relatively adjusting the slides 54, 56 for size of shoe, one has a transverse groove 56 and the other an inclined groove 57. A slide block engages both grooves, and is moved transversely for the relative adjustment by a lever 67, a slot 63 allowing for the reciprocation of the slides. The bars 30 at the end of the work engage the wiper plate 17, 18 by pivots 81. The bars adjacent these engage the plates by slide blocks 82 engaging slots in the pla.tes. The bars 30 slide in radial grooves converging to the centre of the end of the shoe. The apertures 38 through which the tacks are driven are elongated to a greater degree as they are farther from the end of the work, to allow for the treatment of work of different sizes. For wiping over the toe end, the wipers may have lateral overlapping portions. The wiper plates are thin, and, to prevent flexing, are supported between lower plates 80 and the tackers. The remainder of the machine may be constructed as described in. Specification 191,477.

Patent GB-362955-A (GB)
Title: Improved process for the silicification of fibrous materials of vegetable origin
IPC: D06M16/00
Filed: 1930-08-06
Abstract: In the silicification of fibrous materials of vegetable origin, such as cotton waste, wood or cellulose fibres or straw, for the production of structural elements, the materials are opened up by the action of acid-forming bacteria until the materials are completely penetrated by acid, whereupon the growth of the bacteria is stopped and the fibrous materials are saturated with water-glass.  The bacteria preferred are those which form lactic, acetic, citric or tartaric acid.  In an example, chopped straw is added to a solution to which whey containing bacillus lactis aerogenes has been added and the mixture allowed to stand at 30-40 DEG  C. for 4-6 hours, after which the bacteriological process is stopped by brief heating to 85-100 DEG  C. or longer heating to 63-65 DEG  C. and a 5 per cent water-glass solution is added.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification of the process in which the fibrous materials are saturated with an organic acid, particularly a fruit acid, and the bacteria are then added.  This subject matter does not appear in the Specification as accepted.ALSO:In the silicification of fibrous materials of vegetable origin, such as cotton waste, wood or cellulose fibres or straw, for the production of structural elements, the materials are opened up by the action of acid-forming bacteria until the materials are completely penetrated by acid, whereupon the growth of the bacteria is stopped and the fibrous materials are saturated with waterglass.

Title: Process for the polymerisation of butadiene 1:3, homologues and analogues thereof
IPC: C08F36/04
Filed: 1929-08-02
Abstract: 337,460. Carpmael, A., (I. C. Farbenindustrie Akt.-Ces.). Aug. 2, 1929. Caoutchouc, synthetic.-In the polymerization of diolefines by means of alkali metals such as sodium, the metal is enclosed in a small container within the reaction vessel, the small container having openings. The diolefine first entering through the openings becomes polymerized rapidly and when the small container is completely filled with polymerizate, an excess pressure arises in the small container which forces the polymerizate containing alkali metal through the openings into the reaction vessel causing the contained diolefine to polymerize. The perforated container may be made of glass or metal, and some of the holes may be of comparatively large diameter, or they may have the form of slits. The process may be effected in two stages, the perforated container being placed in a small vessel containing diolefine and, when the polymerization is complete, the perforated container is then placed within the principal reaction vessel. The relatively small quantity of diolefine first polymerized may be a homologue or analogue of the main reaction charge. The polymerization may be effected in presence of a diluent, and, in addition to the alkali metal, other polymerizing agents may be added. Examples describe the use for containing the sodium of glass, nickel-plated brass, and iron tubes having openings and the use of diethylene dioxide as a diluent.

Title: Improvements in or relating to flushing tanks
IPC: E03D1/07
Filed: 1920-08-16
Abstract: 168,769. Vazifdar, N. R. Aug. 16, 1920. Siphon-discharge water-waste preventers; dooraction water-waste preventers. - Two siphons 8 carried by a float 4 and sealed by cups 9 are adapted to discharge the contents of a compartment a into another b connected to a closet basin. When a cord 17 is pulled, a rod 12 is depressed and with it the float and siphons. A cup 6 placed on the top of the float is filled with water, the weight of which retards the rising of the float. The water in the cup 6 gradually escapes through a slit 7. The operation of the cord 17 may be effected by the door-action mechanism shown in Fig. 5. When the door 21 is closed a rod 26 is forced inwards against the pressure of a spring 32. The rod is connected to a lever 35 loose on a spindle 33 and fitted with a pawl adapted to engage quadrantal notches on a wheel 39 which moves with a toothed wheel 40 in mesh with a wheel 41 of half the size. The wheel 41 intermittently rotates a winding drum 47 through levers 44, 49. The effect of the two last motions is that every fourth movement of the door exerts a pull on the cord 17 and thus starts a flush.

Title: Apparatus and process for covering the links of a sliding-clasp fastener with fabricbands
IPC: A44B19/34
Filed: 1939-08-19
Abstract: 541,586. Sliding clasp fasteners ; sewing machines. RADO, L. Aug. 19, 1939, Nos. 23936/39, 31329/39, 32367/39, 4810/40 and 8285/40. [Class 44] [Also in Group VII] Covering strips for sliding-clasp fasteners are secured by loose stitches, between which the fastener members are inserted. In one form. a pair of super-posed covering tapes are secured by loose stitches near one edge. The stringer tape carrying the fastener members is then inserted between the strips with the members protruding. Another form, Fig. 3 shows the stringer tape 2a with beaded edge secured by loose stitches 3 to the middle region of a wide cover strip 1. When the fastener members have been applied to the beaded edge, the left portion of strip 1 is folded over the right portion along line 6, to hide the stitches, and the double thickness is then carried round to bring the stitches between the fastener members and super-pose the cover over the fastener members and stringer tape, as seen in Fig. 6, which shows the folding over process applied to a narrower tape 1 to which a separate additional cover strip 7 has been secured by stitches 8. The additional strip 7 may alternatively be secured by adhesive, or omitted as in Fig. 8, which shows the invention applied to a known form of fastener member disposed so that the cover strip lies on a flush o rflat surface, the upper plate of the slider, not shown, being correspondingly flat. The interengaging projection 27 and recesses are non-circular. The loose stitching may be effected with the use of any suitable spacing device between the parts being stitched, the first Provisional Specification suggesting a flat brush as suitable. Fig. 7 shows a sewing- machine arrangement in which the stringer tape with attached fastener members is fed between fixed upper and lower guide plates 18, 19 and an upper hinged flap 20, parts 19, 20 having registering grooves 22 to accommodate the fastener-members. The stringer tape 2a passes below a spacer foot 9 over which the cover strip 1 is fed under an adjustable guide 11 having a perforation for passage of the needle 12. The stitched tapes pass under a presser member 16. The lower face of foot 9 has a guide groove in line with groove 22. In a modification the fastener members are applied to the beaded edge of the stringer tape between member 9, 16, the latter being stated to serve for compressing the fastener members on to the tape. In this arrangement parts 18, 20 are omitted and the groove in member 9 is just of sufficient size to accommodate the bead on the tape. The subjectmatter of Specification 519,002 is disclaimed.

Patent GB-887964-A (GB)
Title: Improvements in eddy current couplings, clutches, brakes and dynamometers
IPC: G01L3/22
Filed: 1960-07-11
Abstract: 887,964. Eddy current apparatus. EATON MANUFACTURING CO. July 11, 1960 [Jan. 25, 1960], No. 24051/60. Class 35. In an eddy current coupling, clutch, brake or dynamometer comprising a magnetic field member spaced by a gap from a rotatable inductor, the latter has coolant passages through which coolant is axially directed by centrifugal force from a scoop with which is associated a spider which moves through the gap additional amounts of coolant which the passages may be unable to accommodate. Field member 33 carries a magnetic pole assembly 39, comprising a ring 41 supported by a non-magnetic ring 43, the members 33 and 41 carrying spaced interdigitated polar teeth 45. When the field coil 49 is excited, a toroidal loop of magnetic flux, a half-section of which is diagrammed by line L, interlinks the field member and the inductor 19, producing eddy currents upon relative rotation. The coolant, water, enters by inlet 27 and boss 25 to the scoop 14, and passes outside inductor drum 19 via passages 16 between fins 4, 6, before escaping under centrifugal force at outlets 53 into the casing 3. A tachometer generator 59, driven by shaft 11, supplies current to the exciting circuit of coil 49 so as to control excitation in accordance with the speed of the shaft. Excitation increases with decrease in shaft speed, and vice versa, thus controlling the speed of shaft 11. A temperature-sensing thermostat may be introduced at 20 and so arranged that increased coolant temperature causes more coolant to be admitted into inlet 27. From this cause, or from clogged passages, additional coolant builds up and overflows into gap G, giving " wet-gap " cooling. If poles 45 become immersed unsteady action gives a signal warning of excessive overload or clogged passages. In a further modification (Figs. 3-5, not shown), the inductor may be a pair of cylindrical sub-assemblies joined by a small ring, the cylinders having openings through them for coolant passage. The passages may be formed by axial fins engaging inner and outer cylindrical components or may be holes bored axially in a cylinder of integral form. Manual control of the water volume may be used, excessive temperature being observed at a thermometer in an opening such as 40.
