Title: Improvements in or relating to sound reproducing machines
Inventor: CHURCHILL JOHN ADRIAN
IPC: G11B17/16
Filed: 1959-06-15
Abstract: 909,859. Automatic gramophones. FOSTERMALLARD Ltd. June 15, 1960 [June 15, 1959], No. 20454/59. Class 40 (2). In an automatic gramophone for playing both sides of records, as described in Specifications 909,855 and 909,860, the setting down position of the pick-up is determined by a pair of feeler members moving outwards horizontally as one against the underside of the next record, but movable relatively to each other in a vertical direction whereby the diameter of the next record to be played is detected and a sizing stop is set accordingly. When an automatic cycle by a cam-disc 58 is initiated at the end of a record, or when the machine is first started, a feeler-carrying arm 99 is moved from the position shown in Fig. 5 by links 109, 117, controlled by the cam-disc 58, to the position shown in Fig. 7. Continued rotation of the cam-disc causes the link 117 to move the arm 99 outwardly so that the pair of feeler members 134, 135 trail outwardly across the lower surface of the bottom record of the stack. During such movement, a latch member 93, Fig. 3, engaging a solenoid plunger 88, is drawing a stop member 79 counterclockwise about a pivot 81 into the path of a plate 62 fixed to the pick-up arm shaft and having teeth 64, 65, 66 corresponding to the setting down positions for various size records. When the feeler members 134, 135 reach the edge of a record, as in Fig. 8, the tilting thereby produced causes a shorting contact 142 between conductors 136 and 137 to be removed so that the circuit of solenoid 86 is broken, the latch member 93 is freed and stop 79 is left in the path of the appropriate tooth 64, 65 or 66. During a later part of the automatic cycle an arm 68, having leaf springs 77 with pips 78 thereon, is swung counterclockwise about a pivot 69 until the pips 78 engage radial grooves 67, Fig. 3, in plate 62, swings the pick-up first outwardly, and then inwardly until one or other of the teeth 64, 65, 66 engage the stop 79. At this point the pips 78 are forced out of the grooves 67, leaving the pick-up in the correct setting down position.

Title: Improvements in or relating to machines for grinding cylindrical bodies
IPC: B24B5/04
Filed: 1926-08-20
Abstract: 280,997. B.S.A. Tools, Ltd., and Ogilvie, W. Aug. 20, 1926. Centreless grinding; gauges. - A centreless grinding machine having peripherally opposed grinding and governing wheels, has means, which are employed when grinding tapered or shouldered work, for automatically feeding the grinding-wheel up to the operative position and for withdrawing it, and also has means for adjustment of the movement of the wheel and means for ejecting finished work. The grinding- wheel 4 is carried by a slide 3 moved by a screw 1 upon which is loosely mounted a sleave 6 having thereon clutch teeth 26 and having also an arm 8 engaged by a link 15. The link is reciprocated, to oscillate the sleeve, by a lever 10 actuated by a crank or a cam driven through a clutch 12 from the main drive of the machine, and the link is made in two parts 15, 16 having between them an adjustable spring 20, whereby, when the rotation of the sleeve 6 is stopped by an arm 22 thereon and a stop 21 to arrest the inward feed of the grinding-wheel, the link mechanism may overrun slightly. The screw 1 has slidably keyed thereon a capstan wheel 5 movable by a nut 29 to engage clutch teeth 24 with the teeth 26 on the sleeve, whereby the automatic feeding of the wheel operates. The work is ejected on the reverse movement of the sleeve 6 by a rod 39 actuated, through a link 35 and an arm 34 carried by a rod 31, by an abutment 30 on the sleeve 6, which engages a spring pawl 33 carried on the rod 31; a spring 40 retracts the rod 39. The rod 39 is adjustably carried by a bar 38 and a fine adjustment is effected by a nut 41 which engages a screwed part of a block 42 carrying a roller 37 engaging the link 35. A projection 46 of the block serves, by abutment against adjustable nuts 45 on a rod 44, to limit the rearward movement of the ejector.

Title: A method and apparatus for the thermal fission of hydrocarbons
IPC: C10G9/36
Filed: 1958-06-27
Abstract: <PICT:0828772/IV (b)/1> Unsaturated hydrocarbons, particularly ethylene, propylene or acetylene, are produced by the pyrolysis of paraffinic hydrocarbons by (1) burning hydrogen produced in the process with a stoichiometric proportion or less of a carbon compound-free oxygen-containing gas to produce superheated steam, (2) contacting the hydrocarbon to be pyrolysed with the superheated steam whereby the hydrocarbon is converted as desired, (3) separating the desired unsaturated hydrocarbons, and (4) subjecting the remaining gas to further thermal fission to produce carbon and hydrogen which latter is recycled to step (1).  The conversion in the pyrolysis step (2) is preferably limited to 60-70% whereby sufficient hydrocarbon material remains to pass to the cracking step (4) to provide sufficient hydrogen to give by combustion all the necessary heat for the pyrolysis.  The conditions in the pyrolysis vary according to the end product, e.g. 800-1000 DEG  C. and 4-0.01 sec. for ethylene or 1000-1400 DEG  C. and 0.05-0.005 sec. for acetylene.  The product is quenched, e.g. by injecting water.  The cracking step (4) may be effected in conventional cracking ovens at temperatures above 1000 DEG  C., the heat necessary being produced by burning the carbon also formed in the process. Any remaining hydrocarbons need not be removed before recycle provided sufficient oxygen is used only to burn the hydrogen which is preferentially burned, so that carbon oxides are not formed. The combustion and pyrolysis steps (1) and (2) are preferably carried out in the apparatus shown in Fig. 1.  Oxygen is introduced by inlet 1 and hydrogen by inlet 2 and together reacted in the combustion chamber 3.  The products pass through the narrow space 4 at high velocity where they are mixed with the starting hydrocarbon introduced by inlets 5.  The pyrolysis occurs in the chamber 6 which surrounds the combustion chamber and absorbs heat radiated therefrom. The reaction products leave by exit 9 to quenching and separation.

Title: Improvements in or relating to tapping machines
IPC: B23G1/18
Filed: 1958-06-27
Abstract: 868,803. Tapping. ATELIERS J. HANREZ S. A. June 27, 1958 [Sept. 7, 1957], No. 20719/58. Class 83 (3). In a curved-shank nut &c. tapping machine .in which the tap 5 is rotated and fed and has a rearward extension rod 6 with a bent end for discharging tapped nuts by centrifugal force during withdrawal of the tap, the tap is fed to the work and withdrawn by means independent of the means for rotating the tap. As shown, the machine spindle 3, splined to a pulley 4 driven by an electric motor (not shown), rotates in an annular piston 9 operative to withdraw the tap, which is fed by gravity assisted by a spring 12 and/or electromagnetic force. Alternatively, the tap may be withdrawn electrically. The feedstroke is terminated by an adjustable abutment 25 on the holder which preferably opens a switch 26, thus de-energizing an electromagnet 29 which re-sets a valve to effect withdrawal of the tap. The valve, in a box 18, delivers pressure liquid from a pump 20 to cylinder 10 through a pipe 11. At the end of the withdrawal stroke an abutment 24 closes switch 26, re-setting the valve and allowing the liquid in cylinder 10 to return to a tank 22. A gating device 31 is reciprocated, in a shoot 16 between a hopper 17 and a guide 14 in which the nuts are tapped, by a double-acting piston 32 fed by a valve operated by an electromagnet 37 controlled by a switch which is operated by adjustable abutments 40, 41 moving with the piston. Flowadjusting valves 34a, 35a are located between the valve and piston 32, the operation of which is preferably synchronized with the movements of the tap. A switch 42 in series with switch 38 is arranged to be closed by abutment 24 when the tap is just clear of guide 14. Electromagnet 37 is immediately energized to change the setting of the gating valve and advance device 31, which is returned upon de-energization of the electromagnet by abutment 41 opening switch 38. Known means may stop rotation of the tap if a defective nut enters guide 14.

Title: Improvements relating to the synchronising of alternating voltage sources
IPC: G01R25/00
Filed: 1944-10-25
Abstract: 591,791. Synchronising. GENERAL ELECTRIC CO., Ltd., WALTER, D. O., and ESPLEY, D. C. Oct. 25, 1944, No. 20742. [Class 38 (iv)] [Also in Group XXXVI] A system for synchronising two alternating voltage sources comprises two pulse-generators which generate trains of voltage pulses having a constant phase relationship with the oscillations supplied by the two sources respectively and a common indicating device which responds to variations of their phase relationship. Switches which operate only when the pulses of one generator are synchronized with the pulses of the other generator may also be provided. Two plates 6, Fig. 1., of a cathode ray oscillograph 5, which are energized by a circuit 6A fed by the A,C, mains 3, deflect the beam of the oscillograph along a circular time trace in synchronism with the mains. Two pulse-generators 1, 2 fed by the mains 3 and an alternator 4 whose frequency is the same or an integral multiple of the mains frequency, generate 'pulse trains having a length of 10 electrical degrees. The pulse train generated at 1 is applied in a positive sense to the grid 7 and the cathode 8 and modulates the beam so that a fixed arc 11, Fig. 2, of the trace is brighter than the rest of the trace. The pulse train from generator 2 causes the potential difference between the cathode 8 and the accelerating electrodes 9, 10 to vary thereby the velocity of the beam so that the radius of the beam changes over a small arc 12. When the pulses are not in phase but their frequencies are equal, the bright arc 11 and the arc of changing radius 12 are stationary, Fig. 2(a). When the pulses are in synchronism the appearance of the screen is as shown in Fig. 2(b). The pulses from generators 1, 2 are also applied to devices 13, 14 which, when the pulses are in synchronism, supply current to a relay 15 which, closes its contacts 16, thus connecting terminals 17 of the alternator to the mains. The circuit, Fig. 3, represented by the rectangles 13, 14 includes normally conducting valves 18, 19. The pulse trains from generators 1, 2 are applied in a negative sense to the grids of valves 18, 19 so that when they are in synchronism potential applied to the grid of valve 22 increases and valve 22 becomes conductive. Relay A thus operates and opens its contact A1. A negative bias is thus removed from the grid of valve 23 which, after a time lag determined by a Miller feed back arrangement, becomes conductive, thereby operating relay B which closes switch 16, The response of valve 22 may be subject to a short delay by associating it with a Miller feed back arrangement and relay A may be used to close the switch 16.
