Title: Improvements in or relating to pulling-over machines for use in the manufacture of boots and shoes
IPC: A43D21/16
Filed: 1926-09-11
Abstract: 281,780. Pochin, F. H., Pochin, H. S., and Bromley, J. H. Sept. 11, 1926. Lasting and pulling-over.-Relates to machines of the kind in which the tacks, by which the upper is secured in pulled-over condition, are supplied to a tack guiding block and fall therefrom into pockets in' a tack carrier, in which they are retained by the tack drivers while the carrier wipes the margin of the upper over the insole, the guide block meanwhile pressing against the side of the shoe to retain the stretched upper after the pincers have released their hold. The invention consists in means for automatically adjusting the carrier and guide block so that their median line is perpendicular to the part of the shoe with which the carrier contacts, so that the tacks are driven at equal distances from the edge of the last. The tack carrier 6 and guide member 21 are mounted on a vertical arm 8 which, in known manner, swings inwardly of the last for the wiping operation. The arm is provided with an arcuate slot 15 of inverted T shape engaging a corresponding bolt secured to the carrier 6. The tack guiding block 21 slides longitudinally of the carrier 6 and is normally retained in the position shown by a spring 24. At one side of the block 21 is a plunger 31 engaging an arm 33 on a rockshaft 34 mounted in the carrier 6 and provided with an arm 35 the end of which is connected by a spring 36 with one arm of a bell-crank lever 38 pivoted on the arm 8. The other end of the bell-crank lever is connected by a link 43 with the carrier 6, a light spring 44 connecting the pivot of the lever 38 and link 43 with an arm bolted to the arm 8. In operation, when the plunger 31 contacts with the shoe the carrier 6 is swung until its median line is perpendicular to the part being operated on. If desired, a second spring plunger may be provided on the other side of the guide block 21.

Title: Improvements in or relating to electric arc converters
IPC: H02M1/04
Filed: 1935-08-09
Abstract: 461,250. Converting. GENERAL ELECTRIC CO., Ltd., RYDE, J. W., and THOMPSON, W.G. Aug. 9, 1935, No. 22577. [Class 38 (ii)] In an arc converter of the kind in which a main arc is periodically initiated by an auxiliary arc extended between the main electrodes by a gas stream, e.g. as described in Specification 429,060, means are provided for prolonging the duration of the auxiliary arc so as to secure reliable ignition of the main arc without the need for increasing the gas velocity to a point which results in turbulence. In one arrangement, Fig. 1, in which the main electrodes 2, 3 are surrounded by screen electrodes 4, 5, the auxiliary arc is initiated between electrodes 2, 4 by the discharge of a condenser 6 through a rotary distributer 10, and is maintained by a back-up circuit fed by a condenser 12. The discharge circuit of the condenser 12 includes a variable resistance 17 by means of which its time constant may be adjusted to such value that the auxiliary arc is maintained for the necessary period to ensure ignition of the main arc. The auxiliary arc is extended by the gas stream admitted at 18 in the form of a loop on to the main electrode 3. In a modification, Fig. 2 (not shown), the condenser 12 is arranged to be charged by the maintaining current for the auxiliary arc and is shunted by a resistance for effecting its discharge after each ignition. In an alternative arrangement, Fig. 3, instead of increasing the time constant of the discharge circuit of the condenser 12, the fixed electrodes 22, 23 of the distributer 10 are increased in length so that repeated discharges of the condensers 6, 12 are effected each cycle. Inductances may replace the condensers as energy storage devices for the auxiliary arc circuits.

A continuous glass ribbon 128 inch wide (Fig. 1) is conveyed past inspection lines and cut transversely by a "Z" cutter and passes to an "S" marker where the sheets are marked more closely than, but in proportion to, desired longitudinal cutting lines.  Alternate sheets are then shunted sideways to one of two "S" cutters, passing through a photo-electric "S" mark detector the signals from which in conjunction with a stepping clock set up the cutters on the "S" cutter which then scores and cuts the sheets.  The "S" cutter apparatus (Fig. 2) comprises conveyer belts 32A-32F by means of which the "Z" lengths of glass are fed to the cutting table, a bridge 37 carrying a plurality of solenoid-operated scoring devices 38 which travel across the glass sheet to score it, and fulcrum elements 58 which act in conjunction with successively operated hydraulic snapping devices 50-R to 50-64 having heads 52. The sheets are then passed on to a further conveyer 36.  Defects in the glass are noted at the inspection lines and details of them are fed into a computer (not described) which determines the position of the "Z" and "S" cuts to produce the glass sheets, in sizes previously programmed, free from defects.  A circuit for the "S" mark detector apparatus and control apparatus is given.

IPC: F01D13/02
Filed: 1962-06-13
Abstract: 961,507. Labyrinth seals; rotary joints. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 15, 1963 [June 13, 1962], No. 22709/62. Headings F2B and F2G. An inlet gland for the supply of cooling water from a fixed supply pipe 5 to a water cooled rotor (not shown) via the bore 3 of the rotor shaft 1 comprises a first labyrinth seal comprising rotatable cylindrical members 33 interleaved with fixed cylindrical members 29 and a series of blades or vanes formed by partitions between radial holes 45 in a part 41 rotatable with the shaft and arranged in the flow path of water leaking past the labyrinth to produce, when the shaft is rotating, an hydraulic pressure opposing such leakage. The members 29 and 33 are integral with a radial flange 27 on a tube 9 and a shell 35 fixed to the shaft 1 respectively. The tube 9 is secured to an end plate 11 of a shell 17 which is partly closed at its other end by a plate 19 and has a drain pipe 21. The part 41 projects from a plate 37 fixed to the shell 35. A second labyrinth seal is formed by co-operating cylindrical members 31 and 43 on the flange 31 and the part 41 respectively and a projection 55 on the shell 35 extends between projections 57 on the plate 19 to form another labyrinth seal. When the rotor is at rest, water leaking radially outward through the first labyrinth seal flows inwardly from the space 51 to the space 53 through the second labyrinth seal and the holes 45 and drains through the pipe 21. When the rotor is rotating, the water in the holes 45 creates, due to centrifugal force, a back pressure opposing leakage through the first labyrinth seal.

Abstract: 464,736. Moulding buttons; counting- apparatus. EPSTEIN, S. Aug. 18, 1936, No. 22721. Convention date, Aug. 19. 1935. [Class 87 (ii)] [Also in Group XIX] Buttons are made from artificial resin by pressing powdered resin into button-like bodies and then bringing the bodies into the final form by pressure and heat. The buttons are made in a two or more stage press, buttonlike bodies and buttons being made simultaneously at each working operation. The button-like bodies M1, Fig. 4, are made by applying powder through a perforated plate L into matrices in a plate 3. The plates 3, L are transferred to a press where they are acted upon by dies 7. The plates 3, L are removed, and the plate 3 with the button-like bodies is applied to another stage of the press which is heated electrically and is provided with upper dies for giving the final form to the buttons. Burrs are removed from the edges of the buttons and from their perforations by passing the buttons M, Fig. 8, on matrices 21 mounted on the links 15 of chains passing over toothed wheels 19, beneath reciprocating punches 22, 27. The plunger part 27 is slidable in the sleeve 22, is urged outwardly by a spring 25 against a stop 26, and carries pins 28 for clearing the holes in the buttons. The finished buttons are counted by transferring them to tubular members 33, Fig. 9, closed at their lower ends by a perforated plate 36 or by a perforated slide 35. When the slide 35 is moved to the right, a button from each member 33 is transferred over a perforation 37 in the plate 36 and falls into a container R, the number of buttons in the container being computed from the number of reciprocations of the slide.

Title: Improvements in or relating to moulds for applying soles and heels to footwear
Inventor: BARKER GEORGE EDMUND
IPC: B29D35/14
Filed: 1956-07-24
Abstract: 859,142. Moulding soles on to footwear. PIRELLI Ltd. July 15, 1957 [July 24, 1956], No. 22911/56. Class 87(2). A rigid, one-piece cavity mould for forming soles and/or heels of rubber or thermosetting resin and attaching the same to uppers comprises a rigid base plate 1 in which the cavity mould 4 is formed and a last 2 mounted for movement about a pivot in an arc relatively to the base plate, the construction being such that it is possible to extract the completed footwear solely as a result of the movement of the last 2. In the embodiment shown, the last 2 is carried by an arm 3 pivotally mounted upon the base of the machine. If the sides of the mould 4 are disposed at such an angle as not to fall within an arc about the pivotal axis of the arm 3 and of radius equal to the distance between the axis and the edge of the mould, the sole and heel unit 7 will be extracted without obstruction merely by the arm 3 being swung upwardly. When a lip 5 is formed on the mould 4 and the sides of the mould are slightly curved, Fig. 2, the above does not apply and it is necessary for the material of the sole and heel unit 7 to have sufficient compressibility to allow its extraction without damage. If required, an outersole of e.g. leather, prevulcanised rubber or plastic may be incorporated by making it slightly smaller than the mould bottom so that the material of the sole and heel unit 7 may flow downwardly during vulcanisation and embed the entire edge of the outersole.

IPC: G21C15/02
Filed: 1958-07-18
Abstract: 897,862. Stud and socket fastenings. GENERAL ELECTRIC CO. Ltd. July 7, 1959 [July 18, 1958], No. 23093/58. Class 44. [Also in Group XL(a)] Baffle members are inserted in channels of a nuclear reactor and the channels are arranged to prevent insertion of a baffle of the wrong size. Fig. 1 shows a nuclear fuel support 5 carrying a baffle in the form of orifice plate 6. The support 5 is held in place by levers 7 which engage spigot 8. The height to which the support can be inserted is limited by steel liner 10; this height varies between channels, and the lengths of the arms of the levers depend on the size of the associated orifice, so that if too small an orifice is inserted in a channel the arms will not clear the top of the spigot and the support will not be locked in place. Each lever carries a horn 12 so that retraction of the lever is impossible if the orifice is too small. A support, once in place, can be released by tool 9 which retracts the levers. Specifications 791,011 and 844,764 are referred to.
