Filed: 1968-06-24
Abstract: 1,220,515. Pipe stoppers; pipe joints. PNEUMATIQUES, CAOUTCHOUC MFR. ET PLASTIQUES KLEBER COLOMBES. 24 June, 1968 [23 June, 1967; 12 Oct., 1967], No. 30110/68. Headings F2G and F2P. A closure member for obturating the open end of a pipe 12 and which will allow the connection thereto of a pipe 15 of smaller diameter, comprises a plug 10 having axial movement limiting means, such as a flange 13, to limit the depth of insertion of the plug into the pipe and resilient lateral sealing means 16 for application to the internal wall of the pipe. The plug has at least two regions 27 defining circles of reduced axial thickness of different diameter from one another and is of a material which is cuttable, the closure member including a respective sealing lip for sealing the plug to a pipe 15 when the latter is passed through a hole formed by cutting the plug around one of the said regions 27. In modifications, (a) the plug has a peripheral groove for the reception of a radially inward flange on the pipe 12 (b) the joint 16 comprises a sealing washer provided with a metal flange and a tapered internal bore which is engaged by a tapered external surface of the plug, (c) the joint 16 is formed in two parts one of which is of a harder rubber than the supple sealing part and has an external groove for the reception of a pipe flange, (d) the plug has integrally moulded sealing lips 28, Fig. 9, of a diameter smaller than the notches 27 and for sealing against the pipe or pipes 15, (e) the plug 10, Fig. 11, is of cast iron or hard plastics material and has a number of holes each closed by a sleeve 32 of rubber, the central part of which forms a diaphragm 33; sealing lips 35 engage the pipes 15, and (f) the joint 16, Fig. 18, is constituted by a lip which is concentric with a skirt 40 forming therewith an annular space 41 in which the pipe 12 is received.

Title: Improvements in or relating to the shaping of shoe uppers
IPC: A43D21/02
Filed: 1926-07-15
Abstract: 284,185. British United Shoe Machinery. Co., Ltd., (United Shoe Machinery Corporation). July 15, 1926. Lasting and pulling-over.-In a step-by-step gripper lasting machine, the upper materials are separated from the side of the last during updraw, to prevent the edge of the insole being raised, and, during overdraw, the grippers move about an axis so arranged that they have a substantial component of movement toward the shoe bottom, without relaxation of the tension of the' updraw spring. The updraw lever is in two parts, pivoted together and connected for movement together by a spring provided with quick adjusting means. The invention is described as applied to the machines described . in Specifications 228,578 and 236,566. The updraw lever is in two parts 218, 224 pivoted together at 222 and normally moving as a whole about a fixed pivot 220. The two parts are connected for movement together by an updraw spring 240 mounted between adjusting nuts and a collar 242 on a spindle 232 passing through a sleeve on the member 218 and pivoted to the member 224. For quick adjustment of the strength of the spring 240 an arm 260 operates a crank pin linked to a lever 248, stops being provided so that on the crankpin being pushed beyond the dead centre position, the spring 240 is compressed a further definite amount. To the end of the updraw lever is pivoted the gripper casing, to which over-draw is given by a cam-operated slide 210. The updraw and overdraw cams are so designed that on the updraw the upper is separated from the side of the last, Fig. 3, to avoid lifting the edge of the insole. On the overdraw the gripper moves about its pivot at the end of the updraw lever, with the effect that the grippers move substantially towards the shoe bottom and avoid undesired increase of updraw force on the upper. Specifications 283,978 and 284,179 also are referred to.

To accommodate bending of the tube 40 the rod 42 may be of reduced cross-section between the portions in contact with the tube, and the opening in plate 36 may be undercut as at 41. As shown, a snap-acting disc 18 covered by a limp diaphragm 16 actuates the switch 34 when the fluid pressure differential between inlets 30 and 32 exceeds a predetermined amount. The tube 40 is, for example, of stainless steel and the rod 42 of tungsten. The tube 40 (as shown) or the rod 42 may be initially curved to provide a bias.

[Also in Division H2] A remote control sign display device comprises a board composed of juxtaposed elements, each of the elements comprising a mobile surface provided with a succession of signs, and means for displacing the surface, each means being a motor comprising an electromagnet having a single coil or a plurality of coils with their axes parallel, and a core or armature having an axis parallel to that of the coil or coils and arranged to rotate through a predetermined angle on application of an electrical impulse to, or reversal of current in the coil or coils, thus displacing the associated mobile surface. The movable surface may be an endless flexible band or film moved by two rollers or may have two ends wound on reels, or may be carried by a rotatable drum. In the embodiment shown, signs are inscribed on a band carried by crown 63 of drum 62. Drum 62 is secured to core or rotor 58. Between coil 56 and rotor 58 is a plurality of polepieces 57, 57<SP>1</SP> alternately mounted on side-walls 61, 61<SP>1</SP> of frame 60. On reversing the current in coil 56, the polarity of field pieces 57, 57<SP>1</SP> is reversed and rotor 58 moves to bring opposite poles of rotor and field into coincidence. Lamp 23 and lens 21 produce an image of the sign on screen 24. In the embodiment of Figs. 2 and 3 (not shown) the signs are arranged on a film (7) moved past window (6) by drum (8). When current flows in coil (9), core (10) is attracted towards the coil and slides in against spring (11) with a turning motion imparted by helical grooves in the mating surfaces. The timing motion is transmitted to drum (8) by means of pawls (16). In the embodiment of Figs. 5, 6 (not shown) movement of drum (17) on which transparent signs are mounted is obtained by means of ratchet wheel (18) mounted on core (10) and pawl spring (19) which is integral with the drum. In the embodiment of Figs. 12 to 14 (not shown), drum (28) which carries a film bearing signs is integral with ratchet wheel (29) to which are attached springs (33), (33<SP>1</SP>) operating on ratchet wheel (30) and armature (31). On impulse activation of coils (34), (34<SP>1</SP>) etc; their cores (39), (39<SP>1</SP>) &c. move armature (31) in rotary reciprocating motion, each impulse effecting one step rotation of drum (28). The colour of the sign can be changed by interposing between the sign and the window coloured transparent filters carried on a rotatable disc operated by an electric motor (Figs. 14, 15, not shown).
