Abstract: 1,084,546. Boots &c. BRITISH UNITED SHOE MACHINERY Ltd. Sept. 10, 1964 [June 13, 1963; April 21, 1964], Nos. 23541/63 and 16422/64. Heading A3B. A vamp is prepared for lasting by clamping the vamp to leave unclamped two generally triangular portions of the vamp, which are arranged apex to apex across the instep of the vamp, and deforming the triangular portions of the vamp into partconical shapes 92, 94 (Fig. 6). The vamp U is clamped between a plate 4, which has an aperture 20 corresponding to the shape of the triangular portions, and two clamping plates 6, 8 having edges which match the aperture 20 and which are held in clamping engagement with the vamp by bolts 24, 28. At each side of the unclamped area of the vamp is a deforming member 10 having a conical portion 52 with a rounded apex 54. The deforming member 10 is mounted on arms 60, 62 which are pivoted, at the apex of the conical surface 52, to the plate 4 by pins 64, 65, and the member 10 can be raised, by links 82, 84 connected to a block 86 on a screw 88, to deform the vamp to the part conical shape 94 shown in Fig. 6. The base plate 4 and clamping plates 6, 8 also have an aperture 26 in the toe region through which a deforming member 14 can be raised, by treadle or pneumatic cylinder (not shown), to produce a dome shaped portion 97 at the toe of the upper and an aperture 30 through which deforming member 16 can be raised to produce a ridge 95, 96 at the throat of the vamp. The vamp U is mulled before being placed in the machine and the deforming members 10, 12, 14, 16 are heated to a temperature of 100 to 120‹C. so that the members initially assist in rendering the vamp deformable and subsequently dry it out to set the deformed shape in the leather. In a modification (not shown) the deforming members may be provided with a source of steam in which case the vamp need not be mulled. Steam is supplied only during the initial stages of the shaping operation so that the heated deforming members will dry the vamp to set the shape in the vamp.

Title: An object seeking and self-steering device
IPC: G01S3/783
Filed: 1939-08-16
Abstract: 546,488. Automatic control systems. THUNELL, K. H., CLAESSON, P. H. E., VIGREN, S. D., and ROST, H. F. Aug. 16, 1939, No. 23621. [Class 38 (iv)] [Also in Group XXI] Steering.-A torpedo, bomb, projectile, aeroplane, ship or other body carries means responsive to the difference in electromagnetic or sound waves reflected from an object and from its surroundings respectively and an electric receiving and reflecting device actuated thereby to steer the body towards the object. Means for emitting waves for reflection may be carried by the body. The steering apparatus may be automatically controlled so that the body is oscillated in two directions at right angles at different frequencies respectively to enable the wave responsive devices to scan an area until an object comes within that scope whereupon the body is steered towards it. Fig. 1 shows an aerial torpedo with a transmitter 7 of ultra-short waves in the focus of a parabolic reflector 8. Reflected waves are received in four tubes 2, 3, 4 provided with filters to pass only infra-red rays of the required wave length. The rays are directed by an apertured disc 25 driven by a propeller 23 in turn upon a receiving device, shown as a photo-electric cell 6. The amplified output of the cell may be connected by a commutator driven by the propeller to two motors in turn each actuating one of two pairs of rudders 11, 12 on axes at right angles. Fig. 5 shows an arrangement wherein two cams 61, 62, the disc 25, commutating means 69 ... 72 and a current generator 22 are driven by the propeller 23. The cam 61 operates periodically a reversing switch to cause relays R6, R7 to produce an oscillation of the body in one plane by servomotor actuation of rudders 11, 12 and the cam 62 similarly controls relays R8, R9 and rudders 107, 109 to oscillate the body at a slower rate in a plane at right angles. When an object comes within the field of the scanning tubes on the body the equality of opposed charges applied from the photo cell 6 to the condensers 81, 82 at each commutation is disturbed and a transformer 100 applies impulses to a relay R2 whereby relays R4, R5 are operated to energize a relay R3 which cuts out the oscillating means and connects the relays R6...R8 to the relays R 2 , R, and the body is steered to or away from the object according to the setting of a reversing switch 48.

Filed: 1923-09-21
Abstract: 217,809. Rotherham, K., and Eyles,. A. E. Sept. 21, 1923. Pencil-holders.-In a pencil-holder of the type in which the lead is fed forward by a plunger held against return movement by a clutch consisting of a ring of balls pressed by a spring against the Interior of a cone, the plunger slides in a reciprocable tube, a clutch is located between the plunger and tube so that the plunger and tube move together in one direction, and a second clutch is provided consisting of a cone and a spring-pressed ring of balls, segments, or wedges to prevent movement of the plunger in the other direction. The plunger G, Fig. 1, is mounted in a tube F which is split near the middle and is provided with a split cone H encircled by a spring E to cause the plunger to be held frictionally by the tube. The tube and plunger are moved forward against the action of the spring E by pressure on a knob D formed as. or mounted in, a closure, for the casing, the spring serving to retract the tube on release of the pressure. Return of the plunger is prevented by a rung of balls K pressed by a spring L. mounted in the removable nozzle B, against the interior coned surface of a sleeve J. By pressing in the knob D to its full extent, the end of the tube F is caused to bear on the balls K, so that the grip on the plunger is released to enable the lead to be returned into the casing. In another construction, the casing is formed from a metal tube, the mechanism being modified to facilitate insertion into the casing from the rear end. In order to obtain a positive feed of the lead, the plunger may be surrounded by a second ring of balls mounted in a cone which is pressed by a spring against a flange on the plunger tube, the balls being held in contact with the cone by a dished steel washer. According to another modification, the tube F, Fig. 4, is split at the front end and is provided with ratchet teeth adapted to engage with similar teeth on the plunger G, the teeth being normally held in engagement by the spring E encircling the coned end H of the tube. To allow the return movement of the tube relative to the plunger, the forward end of the tube F is bevelled and is adapted to engage, when pressed inwards, with the bevelled end of a tube N, to expand the tube and disengage the ratchet teeth. A receptacle Z for spare leads may be provided.
