Title: Improvements in roundabouts
IPC: A63G1/24
Filed: 1923-02-21
Abstract: 212,087. Jofeh, J. Feb. 21, 1923. Roundabouts.-The cars of a roundabout are given an upward movement by means of an inclined plane, the downward movement being effected by gravity after the car has left the incline. As shown in Fig. 2, a shaft 9, driven by belt and worm gearing from a motor 17, carries a frame built up of members 2, 4, 5. An extension 24 of the frame is hingedly connected to a frame 22, which carries a car or cars 21. Wheels 18 running on a track 20 support the main frame and a wheel 27 carried by the frame 22 runs on a second track 28. One or more hinged members 29, which may be raised by hand or by suitable mechanism operated by the rotation of the roundabout, engage the car wheel 27 to raise the cars 21, which then fall by gravity against the action of a dash-pot or similar cushioning device 30 placed between the car support and a second extension 24 of the main frame. The cars 21 rest on cross-bars 4 of the frame 22 and are connected to the frame by links 34, 37. According to the Provisional Specification the radial arms 2 may be hinged to the hub-member 3, the vertical movement being controlled by a dash-pot.

Title: Hanger tab ready-made for application to e.g. a garment without the use of needle and cotton
Inventor: WALLENHOLM IRENE DOROTHY
IPC: A41D27/22
Filed: 1968-02-01
Abstract: 1,221,991. Garment hanger. I. D. WALLENHOLM. 1 Feb., 1968, No. 5220/68. Heading A3V. [Also in Division E2] A garment hanger tab, Fig. 2, comprises a strip 1 of plastics or other resilient material with a barb 2a at each end which is passed through the garment material 3 at two points and engaged in an opening 6 in an end stop 5. An upstanding portion 6a of the end stop prevents withdrawal of the barb. In alternative embodiments initially separate barb devices are secured to the strip by screw threaded means or by a ring on the device through which the strip is threaded. In a further embodiment, Fig. 10, the end stop 11 is integral with the strip 10 and the barb 9a is on a member 9 formed with an enlargement 9b to prevent it passing completely through the garment material.

Title: Improvements in methods of applying ferrules to steel hawsers and the like
IPC: B25B25/00
Filed: 1938-02-19
Abstract: 507,517. Pliers. SWAYNE, E. M. Feb. 19, 1938, No. 5266. [Class 61 (ii)] [Also in Group XXV] A tool for fixing metal bands on steel cables &c. comprising two levers 1, 2 pivoted at 3. The lever 1 is provided with a piece B by which it maybe gripped in a vice, a block D which supports two plungers 4, and slotted guides C for the pins C<1> of a toggle 5. The toggle is pivoted to the lever 1 and to links 6 jointed to the plungers 4 and is operated by the lever 2. To fix a band, a hooked blank G is placed in a half-round notch in the lever 1, so that its slot H is positioned by a snug F. The cable is then inserted and the lever 2 brought down. The band is thus bent until lugs J engage slots of lugs K and are bent over by the action of the plungers 4. The lever 2 is hollowed out at E to make it somewhat springy. The lugs J are clinched by use of a suitable tool. The cable and band can then be severed at the slot H, leaving a ferrule on each cut cable end.

Title: Improvements in the process of peeling willows and apparatus therefor
IPC: B27J3/00
Filed: 1925-02-26
Abstract: 245,631. Heaton, A. Feb. 26, 1925. Willows, treating.-The first operation consists in holding the willow thick end first on a travelling belt B, Fig. 3, which leads them under iron plates A. This effects a loosening of the bark at the thick ends. Still thick end first, they are fed between feed rollers L which lead them to one or other pair of the stripping-rolls F<1>, F<2>, F<3>. These rolls are loose on their spindle S but can rotate in the direction of feed only, under the action of springs E<2>, Figs. 2, 4, which limit the amount of rotation. From the stripping-rolls the willows pass between rollers H, I, J which assist in drawing them through the stripping- rolls. Rolls L, H, I, J are fixed to their spindles and are driven from a suitable engine by belts passing over pulleys X to X<3> the arrangement being such that the rolls H, I, J rotate at progressively increasing speeds. After the passage of a willow through a pair of the stripping.rolls the spring causes a partial backward rotation thereof, throwing off the peeled bark. The rolls may be further backwardly revolved by pulling on an endless rope K wrapped around a projecting sleeve V and passing over pulleys M. Each spring E<2> is attached to an arm of a ratchet E which engages the roll by means of a pawl R. The rolls are preferably covered with indiarubber, which may be ribbed or roughened, and the pairs of rolls are kept pressed together by springs controlled by hand-screws D.

Title: Shearing device for cutting a launching rack-to-missile umbilical cord
IPC: F41F3/055
Filed: 1972-02-04
Abstract: 1359573 Launching rockets FRANCE ARMED FORCES MINISTER OF 4 Feb 1972 [2 April 1971] 5385/72 Heading F3A [Also in Division B3] A cutter for shearing a cable 1 attaching a missile 2 to a launching-rack (not shown) comprises a disc 8 rotatable about a bearing 8a and having an eccentric aperture 9 through which the cable passes and a tensioning cable 11, one end of which is attached to the launching rack and the other end of which is attached to, and passes about half-way round, the disc so as to rotate it and thus cause the edge of aperture 9 to shear the cable on missile take-off. A portion 10 of the edge is bevelled to form a knife. Before take-off, the aperture is located in the half of the disc around which the tensioning cable does not pass so that on rotation the disc blanks off the cable passage opening in the cover 4. Rotation of the disc also shears a retaining pin 14, releases a spring-loaded bush 15 which presses a packing 17 against the underface of the disc and allows a spring-loaded pin to enter the aperture 9 and close a contact 19 for controlling an operation the start of which must precisely coincide with take-off.

Abstract: 652,289. Making tubes. FEDERAL MACHINE & WELDER CO. Feb. 24, 1948, No. 5464. Convention date, April 29, 1946. [Classes 83 (ii) and 83 (iv)] Drawing ; drawing- dies; electric welding.- In making welded tubing a cylindrical blank 3 with a longitudinal seam 7 is drawn through a long combined skelping and electric welding die 1 to upset the seam and then through a sizing die 2 for a final upsetting to relieve stresses due to the release of the blank 3 from the bell 1 and thermal contraction adjacent the seam. The resistance welding electrodes 4, Fig. 3, are inset over the full length of the bell 1. The sizing die 2 is profiled to accommodate the weld bead and may be combined with the bell and separated therefrom by insulation. The blanks are metal sheet rolled or pressed to cylindrical form and in a modification are pushed through the dies. A separator 14 engages between the blank edges to align it with the dies.

Filed: 1957-02-21
Abstract: 853,967. Levelled nickel electrodeposits. WILMOT-BREEDEN Ltd. Feb. 7, 1958 [Feb. 21, 1957], No. 5828/57. Class 41 Level nickel electrodeposits are produced by the addition to an acid aqueous nickel plating bath of a small dissolved proportion of one of the 6-sulphamido, 6-acetamido, 6-nitro, or 6-amino derivatives of coumarin, or of hydrocoumarin sulphonic or a salt thereof e.g. the sodium or potassium salt. The upper concentration given for the first three compounds is saturation and for the remaining compounds is 2À5 gms/litre. The nickel baths may be sulphate, chloride, or Watts type. 6-sulphamido and 6-acetamido coumarin give bright ductile deposits, the former compound having less good levelling properties and the latter a narrower bright plating range, 6-nitro- and 6-amino-coumarin give bright deposits which tend to crazing, while hydrocoumarin sulphonates give ductile semi-bright deposits. Any degradation products of the additives are removable by circulating the electrolyte by means of a pump through an external charcoal-loaded filter. The Provisional Specification refers also to the use of 6-hydroxycoumarin as a nickel plating bath additive. Specifications 622,671 and 622761 are referred to.
