Title: Improvements in or relating to climbing toys
IPC: A63H11/04
Filed: 1948-06-18
Abstract: 639,108. Climbing monkeys etc.; race games. MEDLER, F. G., and MEDLER, L. J. June 18, 1948, No. 16506. [Classes 132 (ii) and 132 (iii)] In a toy monkey &c. climbing on a stick by tightening and slackening a cord passing through the legs, the feet and hands are urged towards each other by a spring or rubber band 16. The monkey, &c. climbs on a stick 5 by a cord 7 when the bight 7a is tightened (by a hand lever 2, not shown), around the legconnecting pins 12, 13 to move up the legs 11 and the body 9. The body thus elevates the shoulder end 9 of the arms 10 whereby the frictional engagement of the stick 5 in a hole in a locking plate 10a between the arms is released, and the arms become free to slide up the stick. On release of the cord the body sinks a little to restore the friction grip of the locking plate 10a but the sinking is limited by the plate 10a coming to rest against a stop 9a on the body. The arms and legs are urged towards the body and each other by an elastic band 16 so that the pins 12 and 13 of the legs slide up on the bight on release ready for the next lift. At the top a coconut 17 may be dropped to the ground by or received by a projection or cup 18 on the arms. The cup 18 first raises the coconut whereby a bent shoulder 23 of a safety pin device becomes free to spring within its hole 22, thus pulling its outer end 20 out of the loop or eye at the top of the coconut to free it. The weight of the coconut in the cup releases the friction grip of the arms and allows the monkey to descend when the cord 7 is slackened. The coconut may be magnetized to hold on to the cup 18 when made of magnetic material. The device may be operated by a clockwork or electric motor with stopping contact 21 at the top when the coconut is released. Alternatively the arms 10 may be rigid with the body. There may be a number of monkeys on sticks to constitute a race game, the cords then being connected to a single actuating lever.

Abstract: 842,462. Automatic bobbin changing looms. DRAPER CORPORATION. May 30, 1957 [Oct. 15, 1956], No. 17167/57. Class 142(2). [Also in Group XXXII] A bunch of weft wound on the tip of the bobbin is drawn off by a suction device before the bobbin is transferred into the shuttle. Weft ends, holding and removing. The tip of the bobbin (not shown) lying in readiness under the transfer hammer is enclosed by an extractor head 87, Fig. 6, on a piston rod 88, the head being urged on to the bobbin by a spring acting on the piston in a pneumatic cylinder 89. When bobbin changing is initiated, air pressure is admitted through a conduit 96 and suction is applied through a conduit 112 leading through the piston rod to the extractor head; the head is thereby moved to the right, taking with it the bunch of weft from the tip of the bobbin. At first, the head occupies an extreme position 87b but, when air pressure is cut off, returns to an intermediate position 87a, where it is held by a latch 100; on the next beat-up movement, a striker 105 on the slay encounters a lug 108 to disengage the latch, whereupon the head returns fully to the left on to the tip of the next bobbin, which has meanwhile arrived under the transfer hammer. Suction is maintained in the extractor head for several picks after transfer so that when the weft is cut at the selvedge the end is drawn completely into the head and through the conduit 112. The suction is produced by injector action of a nozzle 115, Fig. 12, which also acts to blow the weft arriving from the conduit 112 through an outlet 113 into a receptacle. The weft end from the exhausted bobbin is similarly disposed, of by suction generated in a conduit 119.  Magazine. The magazine 421, Fig. 14, contains columns of bobbins 21 which are discharged by gravity into a shoot 20 leading to the transfer hammer; when a column is empty, the magazine slides along sloping rails to bring the next column into register with the shoot. As the magazine slides, a rod 59, supporting the column of bobbins, rides up a ramp 48 and is thereby caused to move along a slot 60 in the magazine. to release the bobbins. The magazine is halted with the bobbins in line with the shoot by a latch 50 engaging the rod 59; when the column is empty, a weighted flap (not shown), previously kept deflected by the bobbins, swings about its pivot 43, causing a finger 44 to raise an arm 57 to disengage the latch 50.

Abstract: 1,65,548. Photographic materials and processes. BELL & HOWELL CO. April 27, 1964 [May 6, 1963], No. 17328/64. Heading G2C. A photo-sensitive composition which may be coated on to a support to provide a photographic film or paper comprises discrete particles dispersed in a water-soluble dispersion medium in which the particles are substantially insoluble, the particles consisting of a combination of two components, (1) an organic halogen compound and (2) an aromatic N-vinyl compound, which combination may be chemical combination, fusion, solid solution or an intimate association of the components. An element coated with the composition gives a negative colour image when exposed image-wise to light and a positive colour image when exposed image-wise to light and then overall to ultraviolet radiation, both images being more fully developed after heating. The imaged elements obtained may be desensitized by treatment with ammonia vapour. Organic halogen compounds used include carbon tetrabromide, iodoform, hexachlorethane and pentabromoethane; N-vinyl compounds include N-vinyl carbazole, N-vinyl indole and N-vinyl derivatives of benzothiazolines, benzoxazolines, benzoxazolones and benzotriazoles; and dispersion media include gelatine, polyvinyl alcohol, hydroxypropylcellulose, starch, starch ethers and water-soluble resins and proteins. The compositions may also contain amines such as hexamethylene tetramine, phenols such as hydroquinone, toluhydroquinone, mono- and di-tertiarybutylhydroquinone, and hydroquinone methyl ether, formamide, dimethylformamide, acetamide and thiourea as stabilizers, beeswax and C12 - C26 fatty acids such as myristic, palmitic and stearic acids and alkyl esters thereof such as spermaceti and isopropyl myristate, colloidal silica, zinc sulphide, morpholine, ammonium alginate, formalin and sensitizing dyes such as pinacyanol. The compositions are made by mechanically dispersing the components and dispersion medium in a high-speed blender or ballmill to obtain rounded, fused particles or a uniform emulsion of liquid globules which solidify on cooling. The components may be combined before dispersing or may be mixed with a solvent such as acetone, benzene, toluene or xylene to assist in the combination. Examples are given of materials yielding negative images. In Example 19 an element containing N-vinylcarbazole and hexachloroethane dispersed in a starch ether is image-wise exposed to ultraviolet, heated and then overall exposed to ultraviolet to give a positive image. Apparatus for using the photo-sensitive material to provide a positive image is described.
