Title: Electric timepiece with an oscillating regulator
IPC: G04C3/06
Filed: 1964-04-29
Abstract: 1,055,295. Clocks and watches. EBAUCHES S.A. April 29, 1964 [May 9, 1963], No.17805/64. Heading G3T. In a timepiece, Figs. 1 to 8 (not shown) a balance 4, 5 carries angularly spaced pairs of opposed magnets 1, 1<SP>1</SP> and 2, 2 which swing either side of a mean position occupied by a pair of coaxial coils 6, 7. Alternating pulses C<SP>1</SP> ,  C, C<SP>1</SP> are induced if a maximum amplitude corresponding to the mid position, Fig.4. These pulses are flanked by secondary pulses A<SP>1</SP>, B<SP>1</SP> and B, A of opposite sign corresponding to the offset positions, Figs. 3 and 5. The balance is maintained by a circuit, Fig. 7 comprising D. C. source 8, 13 of which-ve pole 8 goes to emitter 9 of n-p-n type transistor T, the collector 10 being connected through coil 6 to the + ve pole 13. The base 14 is also connected to + ve pole 13 through coil 7 and a condenser 17 of capacity C.A resistor 18 of valve R is paralleled from pole 13 across the coil 7 and condenser 17. A second condenser 19 of valve C<SP>1</SP> is interposed between collector 10 and base 14 to suppress unwanted oscillations arising from mutual inductance of the coils. The oscillations of the balance are self-starting. The -ve pulses shown chain-dotted on Fig. 6 do not unblock the transistor. Also, the secondary + ve pulses A<SP>1</SP>, B<SP>1</SP>, Fig. 6, are rendered inoperative in normal operation. To achieve this, the valves of R and C are so chosen that the time constant T = CR is large with respect to the period of the pulses to be amplified. Thus at each pulse crossing collector 10, the base current charges condenser 17 to a voltage close to the supply voltage. Between pulses, condenser 17 is discharged and the residual voltage across it is sufficient compared with the secondary pulses A<SP>1</SP>, B<SP>1</SP> to prevent unblocking the transistor. Fig. 8 shows the voltage between emitter and base, the chain-dotted + ve ordinate showing the conduction threshold which is reached only by the voltage corresponding to the main + ve peak C, Fig. 6, thus causing a maintaining pulse through coil 6 at the same time as condenser 17 is charged afresh. The time constant T may be 3À5 times the period of the balance and may be from 1 to 6 secs. The maintaining pulse therefore occurs normally when the field intersecting the coils 6, 7 is a maximum, whereas, when the timepiece is being started, a charging current for the capacitor is supplied from the source and produces a starting pulse. Before the capacitor is charged to its normally maintained variable value, the secondary pulses make the transistor conductive to assist in starting. The timepiece may be regulated by displacement of the pulse relative to the mid position of the balance.

Delivery of articles stored in bulk. - A combined coin-freed vending machine and game comprises ball-releasing mechanism coin-controlled article - delivery apparatus operation of which causes a ball to be released and allowed to fall, a manually operable cup for catching the ball. and means whereby if f the ball is caught, the articledelivering apparatus may be actuated to deliver a second article. After prepayment, one arm 18<a> Fig. 2. of a lever 18 is depressed, and the other arm 18<b> through a link 22 and lever 23<a> raises a slide 27 to rock a bell-crank lever 28, which embraces a pin 80 on a pivoted feeder or escapement 31. When the escapement is rocked, it allows a ball 34 of candv to roll out through a shoot 40 to a delivery tray 35, Fig. 4. The balls of candy are stored in bulk in a hopper 35<1> and pass through a tube 36 and shoot 39 to the escapement. They are agitated and fed to the tube 36 each time the machine is actuated by a collar 37 which is provided with wings 38 and is moved up into the hopper by being connected through a link 41 to the arm 18<b> of the lever 18. The link 41 is pivoted to a lug 42 on the collar. Coin action, mechanical-connection.-A coin in a shoot 13 drops down to rest on the arm 18<a> of the lever 18 moving aside a, swinging latch 16 by engagement with a bevelled arm 16<b> thereon, the latch being pivoted on a. pin 15 projecting back from a sliding coin pusher. The arm 16b returns over the coin and pushes it down to rock the lever 18 when the coin pusher is depressed. The arm 18a is held down by a latch 60 until the coin pusher is returned to normal position. Tivoli billiards and the Like.-A finger 52 on the lever 23<a> raises a column of balls 51 in. a tube 50, the bottom ball being raised above a supporting latch 54 and the top ball being caused to slide down a runaway 53 by a latch 56. It is held by a wire 59 connected to the lever 23<a> until the coin-pusher is returned to normal position allowing the lever 18 to be returned under the action of a spring 63. The ball escapes through an opecing 70 to a balanced trough 71 from which it falls between pins 75 to be caught in a cup 77 slidable on a wire 78. The cup is actuated by a rotary knob 79 through an arm 80, link 81 and lever 82. If the ball is caught, it is carried by the cup to an opening 91 and drops to a trough 92. The cup is then moved back to the right and a depending portion 93 forces the ball along the trough causing it to engage and depress a cam-shaped lever 94. This lever has an arm 96 which raises the slide 27 to deliver a second article. A full stroke of the lever 94 is ensured by a pawl 101 engaging teeth 100 on the lever. The ball escapes through a hole 110 and runs down a track 90 to enter the tube 50 below the latch 54. If a ball misses the cup 77, it is returned to the tube by the track 90.

Title: Method and apparatus for producing refractory metal compacts
IPC: C22B34/12
Filed: 1957-06-05
Abstract: 800,311. Extracting refractory metals. NATIONAL LEAD CO. June 5, 1957 [June 22, 1956], No. 17940/57. Addition to 758,763. Class 82(1): In a process for the production of a refractory metal compact by reacting a halide of the refractory metal and a reducing metal in a fused salt bath, employing a ram-type reactor as described in the parent Specification, the seal of frozen salt which surrounds the compact and retains it in the. reactor is melted sufficiently to enable the compact to be removed from the reactor. As shown, the compact is formed at the lower end 12 of the reaction vessel by pressure exerted by an upper ram and by ram 13 at the exit of the vessel. During the reaction, a seal of frozen salt is maintained between the compact and the vessel by cooling coil 30 and by coolant circulated through the coil of copper tubing 26. For removal of the compact, an alternating current from alternator 27 causes the coil 26 to act as an induction heater and the salt seal is melted thereby enabling the compact to be removed by lowering ram 13. The coil 26; which comprises a number of turns of soft copper tubing 28, is wound on an insulating material, such as a moulded mica composition 32 mounted on asbestos paper 31 wound on to the surface of the reaction vessel, and the outside of the coil is protected by an insulated sleeve 33.

Title: Improvements in and relating to electromechanical control mechanisms
IPC: F16K31/05
Filed: 1955-06-22
Abstract: 770.145. Control of motors. COMPAGNIE DE PONT-A-MOUSSON. June 22, 1955 [June 24, 1954], No. 18087/55. Class 38(3) [Also in Groups XXIV and XXIX] Relates to control mechanism comprising a reversible electric motor and a worm and worm wheel, this mechanism being adapted to shift alternately in opposite directions a driven member, such as the gate of a valve, between two extreme positions. As shown, the motor M drives a worm 30 slidably keyed to a shaft 31 and held against a shoulder 34 by means of spring 35. The worm engages a worm wheel 21, and in one position of a control lever 29, dogs 20 on the worm wheel engage with dogs 19 on a slidable member 13 which is keyed to the load shaft 5. A spring 23 normally holds the dogs 19, 20, in engagement. When the gate of the valve enters into contact with its seat at the end of the valve-closing operation, or meets another obstruction, the wheel 21 stops rotating, the worm 30 urges the gate against its seat, and, incontinuing to screw against the wheel, travels along the shaft 31 and compresses the spring 35. A lever 59 is then pivoted about its axis so that cam 58 is moved to operate switch 50 and to interrupt the motor circuit. To open the valve the motor is reversed, and, initially, the worm 30 screws in the opposite direction until it abuts the shoulder 34. Teeth 55 on a plate 24 fixed to the shaft 5 drive a gear 54 and a pointer 56 for indicating the opening of the valve. A cam 51 rotates with shaft 52 so that, when the gate is opened, a switch 49 interrupts the motor circuit. If no electricity supply is available, the lever 29 permits operation of the gate by means of handwheel 18, shifting of the lever causing fork 27 to slide the member 13 upwardly against the action of spring 23 so as to separate the dogs 19, 20, and engage toothed ring 14 with gear 15. The member 15 is locked in its upper position by means of nose 36 which is adapted to engage hooks 37 or 38 disposed on spring-biased retaining pawls 39, 40; having a common pivot pin 41. The pawlsco-operate with lugs 44, 45, fixed on the driving shaft 31. If, at the beginning of manual operation, one of the lugs 44 or 45 is positioned in line with the pawl 39 or 40, this pawl being therefore retracted, the locking of the member 13 in its upper position is undertaken by the other pawl. When the motor M is started with the member 13 locked in its upper position, the lugs 44, 45, engage the pawls 39, 40, and release the member 13 which is spring-returned into the position in which the dogs 19, 20, are engaged.

Title: Process for the removal of sulphur trioxide from hot gases
IPC: C01B17/60
Filed: 1959-05-29
Abstract: <PICT:0872984/III/1> Sulphur trioxide is removed from a hot gas by bringing the gas, at a temperature in the range 150 DEG C. to 250 DEG C., into contact with a free carbon-containing adsorption agent, which may have initially low surface activity (e.g. charcoal, peat coke, semi-coke, or lignitic carbonisation coke) or may be active charcoal, for the adsorption of SO3 as such, and subsequently heating the adsorption agent in the range of 300 DEG C. to 600 DEG C. to convert the SO3 to SO2 and regenerate the agent by driving off the SO2 produced.  Where the gas also contains SO2, this may be removed by contacting with more of the adsorption agent below 200 DEG C., and such adsorption agent may be subsequently used in the SO3 adsorption stage.  Heat may be removed from the gas in a heat exchanger between the stages.  As shown, SO3-containing gas enters the adsorber 1 through the inlet 2 and leaves by an outlet 3 to pass to a heat exchanger 4, finally leaving at 7, cold air passing into the heat exchanger 4 at 5 and leaving for use as combustion gas at 6.  The used adsorbent passes to a regenerator 9 where it is heated in the range 300-600 DEG C., the SO2 produced issuing at 10 and the regenerated adsorbent passing into a separating screen 11 where adsorbent fines and ash carried by the gas are removed.  Where both SO3 and SO2 are to be removed, the adsorber is divided into upper and lower sections, the hot gas being introduced into the lower section, where SO3 is removed, and the exit gas being led back, after passage through a heat exchanger, into the upper section, where SO2 is removed.  In both cases the regenerated adsorbent is recycled to the top of the adsorber. Steam, metal salts, or other catalytic materials promoting oxidation by free oxygen may be added.  A hot scavenging gas, e.g. part of the gas produced by regeneration and appropriately heated, may be used in the regenerator, and the sulphur dioxide may be recovered from the regenerator or scavenging gas by washing with an aqueous solution and/or organic solvent or by adsorption on solid material, and the heat contained in the regenerated adsorbent may be used to redistill the sulphur dioxide from the washing agent or solid material.  Specification 824,517 is referred to.
