Title: Improvements in or relating to cold-gas refrigerators
IPC: F02G1/043
Filed: 1961-06-23
Abstract: 988,241. Valves. PHILIPS GLOEILAMPENFABRIEKEN N.V. June 23, 1961 [June 27, 1960], No. 22837/61. Heading F2V. [Also in Division F4] A valve for controlling the supply of gas from the expansion chamber of a cold-gas refrigerator (see Division F4) in which the pressure varies sinusoidally comprises a housing 41 connected by a duct 42 to said chamber, and a plug 43 which is screwed into the housing and has a bore 44. The latter communicates with a chamber 47 in which a helical spring 48 is arranged between an adjustable piston 49 and a valve body 51 having a seating 52 formed on the plug 43. The body 51 is guided by means of a pin 53 in a bore of a head 54 which is screwed on to the plug 43 and has further bores 55 communicating with the duct 42. When the pressure in the expansion chamber drops the spring 48 urges the valve body 51 into an open position and gas from the duct 42 is supplied to duct 44. Rising pressure in the expansion chamber causes the valve to close.

Abstract: 361,950. Boot making machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., Union Works, Belgrave Road, Leicester. July 31, 1930, No. 23058. [Classes 17 (i) and 112.] Trimming; boot-sole sewing-machines.-Relates to shoe manufacture bv machines wherein an operation is performed progressively along the sole margin of a jacked shoe during the relative traverse of a tool and the shoe, the relative tipping of the shoe and tool being mechanically controlled during such traverse, and consists in guiding the work by a templet in predetermined position with respect to the shoe, positioning means being provided at predetermined locations on the shoe. The operation may be trimming, in which case the trimmed edge may serve as a guide for the seam securing the outsole to the welt. An appliance is described for marking the sole for positioning the templet. This appliance comprises a plate 32, Fig. 11, secured to a fixed support 38 and formed with a guideway for a sole pricking pin 40 actuated by a lever 42 slotted at its free end to engage a pin 24 engaging a hole in the last as described in Specification 206,176, [Class 17 (i), Boots and shoes, Apparatus for making &c.]. The shoe is engaged at the sides of the toe by rolls 46 on arms pivoted to the plate 32, geared together and urged together by a spring. An adjustable toe gauge 44 is provided, and a spring plate 56. The templet 20, Fig. 4, has a locating pin at its forward end to engage the depression formed by the pin 40, and a slot at its rear end to engage the pin 24. The shoe is mounted on a jack of the kind described in Specification 324,367, [Class 17 (i), Boots and shoes, Apparatus for making &c.], provided with an arm 90 pivoted to the lower portion of the heel support 60 and carrying a clamp for the templet. This comprises a ball-jointed presser foot 86 on a plunger having a pin 96 engaging a cam track in a clamping lever 92. The jack is actuated and controlled as described in Specification 324,367, and, as the shoe is unclamped at the conclusion of the cycle the slight downward movement of the shoe releases the pressure of the foot 86 and allows the lever 90 to fall away from the shoe. The templet 20 is engaged by a guide 108, Fig. 4, secured to the exhaust nozzle 112 for removing chips and apertured for the passage of the cutter 100, which is mounted on the shaft of an electric motor 106. A gauge and guard plate 104 is secured to the cutter shaft and engages the crease between the upper and welt to determine the vertical position of the shoe. The trimmed edge may be used to guide the shoe in an automatic outsole sewing-machine of the kind described in Specifications 114,842 or 292,193, [both in Class 112, Sewing &c.]. The work table 120, Fig. 15, entering the crease is provided with an edge gauge 124. The shoe sole edge may then be finally trimmed in a machine of the kind used for the rough rounding, fitted with the same or a different templet.

Title: Automatic exposure regulator for photographic cameras
IPC: G03B7/083
Filed: 1959-07-06
Abstract: 922,615. Photographic cameras. DURST A.G. BOZEN FABRIK PHOTOTECHNISCHE APPARATE, and J. DURST. July 6, 1959 [July 7, 1958], No. 23160/59. Class 98 (1). A combination comprises a photographic shutter, a diaphragm, a photo-electric exposure meter including a moving-coil galvanometer, and a fluid-operated control device separately connected both to the shutter and to the diaphragm for controlling the same during running down of the shutter, in accordance with the position of the galvanometer coil, the arrange. ment being such that retardation of shutter movement resulting in lower shutter speed is accompanied by increase of diaphragm aperture. The embodiment shown operates as follows. When by means of a lever 3 a shutter 2 is released, an operating element 4 connected to the shutter master member (not shown) rotates counter clockwise and carries with it by means of a pin 6 on a lever 5 a double-armed lever 9. This lever 9 is connected to a pneumatic retarding mechanism comprising a piston 12 having a number of inlet openings 13. The speed of movement of element 4 and of the shutter itself depends on the extent to which apertures 13 are covered by a valve vane 28, carried by a spindle 27 of an exposure meter galvanometer 25. Reduction of pressure in the main cylinder 11 during movement of piston 12 is transmitted through a passage 14 to a second cylinder, thus tending to cause a piston 20 to rise. Such movement rotates a diaphragm control ring 16, which rotation is resisted by the springs 21-24 as they successively come into operation. The galvanometer spindle 27 also carries a pointer 29 for co-operation with a light value scale visible through a window 30. Specification 748,406 is referred to.

Abstract: 642,504. Automatic control systems for cathode-ray tubes. COSSOR RADAR, Ltd., and LEVIN, A. Sept. 3, 1948, No. 23303. [Class 38 (iv)] To maintain constant the current in the electromagnetic focusing coil FC of a cathoderay tube (not shown), irrespective of small variations in the E.H.T. voltage applied to the electrodes of the tube, the major portion of the current passes through the arm 8, 5 of a Wheatstone bridge and the voltage drop across the part of the adjustable resistance VR1 included in the arm, is compared with the voltage across arm 4, 5 derived partly from a constant voltage source 7, e.g. a neon tube, and partly from the E.H.T. voltage via an adjustable resistance VR2. Unbalance due to variations of the focusing current is detected by the valve 9 which controls the valve 1 so as to restore balance. The constant voltage device 7 may be fed from a separate source so as to reduce drain on the E.H.T. source.
