Title: Improvements in or relating to tie, trouser and like presses
IPC: A47G25/72
Filed: 1929-02-27
Abstract: 326,647. Cutler, E. N. Feb. 27, 1929. Presses.-Trouser, necktie, and like presses are made with the press boards hinged together in such a. manner as will allow when the boards are folded together a certain freedom of movement at the hinged connection. This enables an even distribution of pressure to be transmitted to the garments. In the case of multiple presses the hingeing occurs alternately at either side " zigzag " fashion to enable the press to be opened at any layer without disturbing other parts. In a modification, the hingeing is obtained by the use of flexible or elastic strips for the hinges. As shown, upper and lower press boards a, bare provided in addition to intermediate boards c. The pressure element may consist of upstanding screws h, fly-nuts h<1> and the usual reinforcing straps i to which the pressure is transmitted. The boards a, b and the intermediate boards c are each hinged to its adjacent boards The upper press board has straps f attached to its edges by screws e and the boards c corresponding straps d similarly secured. The strap f is hinged to the uppermost strap d by means of a pin d<3> capable of a limited movement in a slot d<2> in a downwardly projecting extension f<1> of the strap f. Similar articulation occurs between the succeeding straps d and between the lowermost straps d and the straps attached to the bottom press board. The hingeing occurs, as shown in Fig. 2, alternately on one side and the other. In a modification, the articulation is carried out with the aid of flexible or elastic strips. Any suitable pressure applying means may be employed. The members of the multiple press may be hinged together in the manner of the leaves of a book.

Title: Improvements relating to the manufacture of pads of fibrous material
IPC: A61F13/15
Filed: 1932-03-03
Abstract: 397,920. Making pads for surgical purposes or for use in sanitary towels. ROBINSON, V. 0., Wheat Bridge Mills, and HEATH, F., 22, Wheatbridge Road, both in Chesterfield, Derbyshire. March 3, 1932, No. 6471. (Class 81 (ii).] A method and apparatus for forming surgical and like pads from fibrous material such as that made from layers of very thin cellulose, involves rolling the material in a space surrounded by said rollers rotating in the same sense and subsequently ejecting and flattening the roll by the reversal of the direction of rotation of one of the rollers. The reversed roller may be displaced to form the necessary space for flattening and ejection. A further feature of the invention involves feeding a web of material and by the reversal of certain of the feed rollers rupturing the web to produce the necessary amount of material for producing a. pad. As shown in elevation in Fig. 1, and diagrammatically in Figs. 4 and 5, material is fed from a roll Z by a conveyer 4 to rollers A .. D. After the required amount of material is fed, rollers A, B which have previously been raised, are lowered to grip the material, and the roller C, conveyer 4, and roll Z, are reversed in direction of motion and the web is torn as indicated at X in Fig. 4. Subsequently the severed portion passes along a conveyer 3 to the pad-forming rollers E .. H, which are rotating in the direction indicated by the arrows in Fig. 4. On reversal of motion of the roller G the pad is flattened and ejected, the rollers G, H separating to effect this, as shown in Fig. 5.

Title: Improvements in cross-bar switches for use in automatic telephone systems
IPC: H01H67/26
Filed: 1949-03-11
Abstract: 658,210. Cross-bar switches. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 11, 1949, No. 6738. Convention date, March 15, 1948. Addition to 647,506. [Class 40 (iv)] A cross-bar switch according to the parent Specification is modified in that the movable contact wires are originally formed in the shape shown in Fig. 4 so that the tightening bows 4 are wide enough to slide on to their supports 6 without friction. On mounting in the switch, which is effected by placing successive tightening bows in turn on their respective supports, the movable contact wire is deformed into the shape shown in Fig. 1, so that the strain in the contact bows 1 causes the tightening bows 4 to grip their supports 6. Each actuating-comb or catch 3 carries triangular projections 13 which force the fixed contact wires 10 apart when the catch 3 is operated, thus cleaning the points of contact by friction between the contact bows 1 and the fixed contact wires 10 sliding over them.

Title: Improvements in and relating to the manufacture of bolting cloth, grit gauze and the like
IPC: D06M15/51
Filed: 1942-05-19
Abstract: 557,486. Treating textiles with liquids &c. COURTAULDS, Ltd., and McFARLANE, R. A. May 19, 1942, No. 6773. [Class 15 (ii)] Bolting cloth, grit gauze and the like is obtained by weaving in a leno weave artificial thread containing one or more continuous filaments, and causing the warp and weft threads to adhere at their crossings and thus prevent them from slipping over one another by treating them with a non-aqueous solution of a resin-like condensation product of a polyhydric alcohol with a polybasic acid. The condensation product may be modified by heating with an oil or urea or urea-formaldehyde condensation products. When weaving in a leno weave, all or only some of the warp threads may be crossed over one another between successive insertions of the weft thread, i.e. a "full leno" or "half leno" fabric may be obtained. Artificial threads of regenerated cellulose, cellulose acetate, nylon, or synthetic resins may be used. The amount of resin applied to the cloth may be 20 per cent. or less of the weight of cloth. It is sufficient to give stability to the weave and stiffness to the cloth but not so great as to diminish the sieving properties. To remove any film which may be formed over the interstices, the cloth may be passed, while wet with the solution of resin, over a rod or series of rods. In an example, a phthalic anhydride-glycerol resin modified by inclusion of castor oil is obtained and mixed with ethylene glycol ethyl ether. A fabric of high tenacity viscose rayon woven in half leno weave is padded with a solution of the resin in benzol and methylated spirits. The fabric is dried on a stenter or similar machine. Specifications 359,897 and 520,579 are referred to.

Abstract: 1382765 Toy aeroplanes; toy vehicles MATTEL INC 13 Feb 1973 [10 Oct 1972] 6965/73 Heading A6S [Also in Divisions Hl and H2] A toy vehicle, &c 11 comprises an electric motor 21 for propelling the vehicle, a rechargeable battery 144 for supplying power to the motor and an automatic system for disconnecting the battery from the motor when the battery has discharged to a predetermined level. The vehicle may be a toy aeroplane, as shown, or a toy vehicle with driven ground wheels. The motor 21 drives a propeller 61 via a gear train 35 and a shaft 59. A pair of small switches 111, (112), Fig. 6 (not shown), are mounted on a pivot plate 121 which is integral with a lever 119. When the lever is rotated in a clockwise direction, a fixed cam surface (84), Fig. 2 (not shown), engages the actuating button of the switch 112 to connect a battery 141 to a radio receiver receptacle 150. The radio receiver energises a coil 201 to rotate a remote control link 202. Rotation of the lever 119 also causes a surface (105) of a cam 97 fixed to a shaft 87 to engage the actuating button of the switch 111 thereby connecting the battery 144 to the motor 21. The rotation of the propeller causes axial movement of the cam 97 against the bias of a spring 109 and provided that the battery has not discharged beyond the predetermined level, the cam surface (105) holds the switch 111 closed. If the battery becomes discharged to the predetermined level, the motor does not displace the cam 97 sufficiently to enable the surface (105) to hold the switch 111 closed so that the battery 144 is disconnected from the motor 21. The radio receiver continues to be energised until -the lever 119 is rotated in an anti-clockwise direction to open the switch 112. A battery charging receptacle 148 is provided to enable re-charging of the batteries 141, 144.
