Title: A last remover
IPC: A43D3/10
Filed: 1950-02-25
Abstract: 691,971. Removing shoes from lasts. RALPHS, G. C. Feb. 26, 1951 [Feb. 25, 1950], No. 4893/50. Class 17 (i). Apparatus for removing a shoe from a last comprises a frustro-conical resilient pad 12 mounted on a piston rod 6 which may be raised and lowered by air or other non-liquid elastic fluid pressure acting on a piston and cylinder device 7, and an arm 14 which supports the last on a pin 16 carried by a head 15 on its upper end and which may be moved relatively to the pad 12 by air pressure acting on a piston and cylinder device 19. The apparatus is carried on a table 2 and bracket 3 both supported on a frame 1. Control of air supply under pressure to the devices 7, 19 is effected by a treadle lever 21 which controls a piston valve 20 having four ports and a pair of cup washers 35, 36 spaced apart and directed towards one another. The valve arrangement is such that, on initial depression of the treadle, the device 19 is operated to move a shoe on the last from a loading and unloading position towards the pad 12 and press the shoe counter against the pad which may have a grooved surface to increase the area of contact. In this position the pin 16 is inclined towards the pad at an angle and cannot readily be pushed off the last. The device 7 is then caused to move the pad 12 vertically to force the shoe off the last. Pressure on the treadle lever is then released to permit the head 15 to swing away from the pad which is then lowered. The pad 12 is held against rotation but may be turned on its axis to offset wear on a particular part of it.

Title: An improved method of, and apparatus for televising cinematograph films
Inventor: OKOLICSANYI FERENC
IPC: H04N3/38
Filed: 1953-02-23
Abstract: 777,443. Television. CHROMATIC TELEVISION LABORATORIES, Inc. Aug. 31, 1953 [Feb. 23, 1953], No. 4962/53. Class 40 (3). Relates to apparatus for televising a continuously-moving kinematrograph film 11 by means of a cathode-ray tube flying-spot scanner 13 and a photo-electric cell 17, the raster on the tube screen being produced under the control of frame and line time-bases 19 and 20 at a rate which is not equal to, or a simple multiple or submultiple of, the picture repetition frequency of the film. In accordance with the invention, an additional time-base 21 is provided which is synchronized with the movement of the film and functions to move the projected raster at the same speed and in the same direction as the film, the flyback of the additional time-base shifting the raster back so that it takes up a corresponding position on the next succeeding film picture and being synchronized with the time-bases 19 and 20 so as to occur during a blanking period. The operation is indicated in Fig. 2 where film pictures A, B and C are shown moving downwards through a gate 12 of twice the height p of a film picture. Both the frame and additional time-bases produce deflections equal to p, and it is assumed that the television raster frequency is greater than the film picture frequency. Thus, at the start of operations, as shown at (a), the raster commences scanning at Xa and moves down with the film, so that, at the end Za of the first raster scan, the film occupies a position as shown at (b). The normal frame time-base fly-back now returns the scanning spot to Xa and the raster proceeds to scan the same film picture, the raster continuing to move with the film under control of the additional time-base. At the moment (c) however when picture A reaches the bottom of the gate, the flyback of the additional time-base occurs. By this time the scanning spot will have reached some intermediate position, such as Ya (determined by the relative frequencies of the television raster and film pictures), but since the additional time-base has an amplitude p, the spot moves to the corresponding position Yb in picture B. Signals produced during the second raster scan thus correspond to complementary parts of pictures A and B. The cycle of operation now repeats, the third raster scan, for example, occupying complementary parts of pictures B and C. The synchronism between the film movement and additional time-base may be obtained by deriving the time-base voltage from a magnetic tape wound-round a drum or other member on one of the spindles of the transport mechanism. In another method, a synchronous motor for the film transport mechanism is driven from fly-back signals of the additional time-base. Reference is also made to a method in which the timing of operations is controlled from the line time-base.

Title: Improvements in or relating to talking machines
Filed: 1947-02-20
Abstract: 628,642. Automatic gramophones. PAILLARD & CIE, SOC. ANON., E. Feb. 20, 1947, No. 4972. Convention date, April 10, 1946. [Class 40 (ii)] In an automatic gramophone, in which initiation of the automatic mechanism is effected at the end of a record by means of a friction-driven tap-tap lever 25 which is coupled to the pick-up arm 19 and engages a rotatable stop member 15 on the turntable shaft 30, the said stop member 15 is provided with ramps 14 on a toothed sleeve 7 which is forced downwardly against an internal spring when the stop member 15 engages the surface 45 on the lever 25 during the accelerated movement of the pick-up arm 19 at the end of a record, so that the teeth 12 mesh with the teeth 42 of a recessed portion 41 of a cycling disc 38. When the said disc 38 has revolved sufficiently for the teeth on the other part of the disc 38 to be engaged, the pin 46 releases the tap-tap lever 25 from the stop ,member 15 so that the sleeve 7 is restored to its normal position, and ceases to drive the disc 38 when the recessed portion 41 is again reached. The construction may be modified to accommodate records with eccentric run-off grooves by the provision of two stop-members 15 displaced from each other by 180 degrees, or the plate 23 may be loose on the shaft 21 and driven inwardly by means of a pin projecting downwardly from the pick-up arm 19. A pin 34 coupled to the sleeve 7 is provided to initiate the automatic mechanism manually when it is desired to reject a record before the end of the playing.

Abstract: 1,215,452. Hydrostatic extrusion. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 24 Jan., 1968 [2 Feb., 1967], No. 5149/67. Heading B3P. A hydrostatic extrusion apparatus has means for bleeding high-pressure liquid from the eextrusion chamber 1, comprising a leak path 23 formed between two contacting members 20, 22 which are loaded to provide a controllable pressure between the contacting surfaces. Member 20 is the extrusion plunger actuated by a main ram 5 and passing through a bleed ring 22 which has a conical surface 24 and is compressed axially by hydraulic pressure in a secondary cylinder 3. This causes radial contraction of the ring 22 on to the plunger 20. Ram 5 is carried by an axially movable crosshead 10 containing a cylinder 8 for a main actuating ram 13. For extruding a billet 29 through die 16, ram 13 is moved to the left to pressurize liquid 30 in cylinders 8, 3 and move the ram 5. Movement of the crosshead 10 and ram 5 is initially restrained by cylinder 14 until the plunger has built up hydrostatic pressure in chamber 1. The crosshead 10 is then released whereby plunger 20 moves into engagement with the billet which is thus extruded by combined hydrostatic and direct pressure. During extrusion liquid is bled along path 23 into cylinder 3. In another embodiment, Fig. 2 (not shown), the extrusion chamber 1 is formed by segments (31) and has a liner (32) whose rear end (34) is contracted on to the plunger 20 to provide the bleed path. In a further embodiment, Fig. 3 (not shown), the bleed ring (42) surrounds the extrusion die 16. In another embodiment, Fig. 4a, the extrusion plunger 127 has an enlarged rear head 128 with an annular surface 131 contacting the end of the main ram 104. The bleed path is provided by duct 134, contacting surface 131, outer chamber 133, and passageway 135 leading to atmosphere. The extrusion chamber is formed by segments 113, Fig. 5 (not shown), having an inner liner 118 and an outer sleeve 116 which is pressurized during extrusion of the billet 137 by the liquid 138 in chamber 102 which is itself pressurized by forward movement of the ram 104. In a modification, Fig. 6 (not shown), a continuous billet (147) is used and passes through the ram 104. (For Figures see next page.)

Abstract: 545,212. Cutting washers. UNITED STATES RUBBER CO. April 22, 1941, No. 5163. Convention date, May 4, 1940. [Classes 31 (i) and 31 (ii)] Washers &c. of uniform volume are cut from a strip 32 of plastic material by mechanism comprising a plunger 34 moved down by a cam 15 to a pre-determined position relative to the cutting bed 66 so as to compress the material under the plunger to a definite thickness prior to severing and punching the washer by means of. the cutting die 30 and punch 45 carried by the sliding cross head 18 actuated by the eccentrics 11, 12. A striker 69 on the sliding cross head assembly actuates a valve 68 of an air supply pipe 48 admitting air to bores in the plunger and punch to eject the punching 77 through the tapered bore 65 in the cutting-bed, whilst the washer 75 adhering to the end of the plunger 34 is projected down a shoot 76 by a jet of combined air and water from a nozzle 72 supplied by a water pipe 74 and air pipe 71 with valve 70 actuated by another striker on the cross head assembly. In a modification the plunger instead of being positively actuated is forced down on to the material by a heavy spring interposed between the plunger and cutting die. The material 32 is advanced intermittently by endless conveyer belts 59 and rollers 60, the former actuated by a ratchet 57 and pawl 56.
