Abstract: 840,001. Circuits for reproducing sound. SANDERS (ELECTRONICS) Ltd., W. B. Sept. 22, 1958 [Jan. 21, 1957], No. 19526/57. Class 40 (4). A tone-correcting circuit for a magnetized tape or wire reproducing-head 1 feeding a transistor amplifier 3 consists of a circuit shunted across the head and comprising a resistance 6, a condenser 7 and a parallel-tuned circuit 10, 11 arranged in series. The resistance 6 is effective to shunt the output of the head at the middle range of frequencies, but at the lower frequencies the shunt effect is decreased by the increase of impedance of the condenser 7 which ultimately resonates with the inductance of the pick-up head. At the upper frequencies the tuned circuit 10, 11 resonates to increase the shunt impedance so decreasing the shunting effect of the resistance 6. Switching means may be provided together with a transistor oscillator 13 to enable the head to be used for recording a microphone or radio signal, as well as for reproduction.

Title: Method of refluelling reactor
IPC: G21C13/02
Filed: 1971-06-09
Abstract: 1337090 Fuelling reactors WESTING- HOUSE ELECTRIC CORP 9 June 1971 [8 July 1970] 19705/71 Heading G6C In a method of refuelling a nuclear reactor having a lower package including, within a pressure vessel, a core having fuel assemblies to be replaced and lower internals, and an upper package including the head of the pressure vessel, the upper internals, control rod drive mechanisms and housings, and electric cables, bolts locking the head to the pressure vessel are released, the upper package with all equipment attached is moved in a single lifting operation to a prepared location away from the lower package affording access to the core, and the fuel assemblies are replaced. The upper package also includes a missile shield and it is to a lug on this shield that a lifting device is connected for removal of the upper package. The removal of the control rods from the core with the upper package is compensated for by an increase in the concentration of neutron absorber, e.g. boron 10, in the reactor coolant. Typically, the refuelling can take place in a few days, at intervals of three to six months. During refuelling, a portion of the fuel assemblies is replaced. Because of the facility for rapid refuelling and the consequent lower time cycle, the fuel can be of lower enrichments and the concentration of neutron absorber in the reactor coolant reduced. All replacement fuel assemblies can be moved in a cart into the reactor containment in a single operation and replaced from the cart, or the assemblies can be moved individually into the containment. The invention is described with particular reference to a pressurized water reactor.

Title: Improvements in devices for storing and selectively displaying time-tables, index cards and the like
IPC: G09F11/32
Filed: 1936-07-16
Abstract: 483,723. Changing signs. STEFFEN, O., and MATTES, F. July 16, 1936, No. 19795. Void. Convention date, July 16, 1935. [Class 3 (i)] [Also in Group XV] An apparatus for storing and selectively displaying time-tables, index cards, or the like 6 comprises a number of compartments 5 for receiving the cards, and a conveyer 11 adapted by engagement with projections on the cards to convey selected individual cards into displaying position, operation of the conveyer being prevented when the selecting device is not set, and operation of the selecting device being prevented whilst a card is withdrawn from the compartments. The conveyer 11, which consists of steel bands, is mounted in a vertically movable frame set in certain positions according to the particular card it is desired to display by means of a spring-pressed plunger 36, Fig. 8, engaging one of a series of notches in a rack 35 on the frame and constituting the selecting device. Each card has a bar attached to one edge thereof and the conveyer 11 is provided with arms adapted to engage the projecting ends of the bar to convey the card to the displaying position at the upper part of the apparatus. A curved channel 23 is provided on the conveyer frame to guide the card into its compartment when it is returned thereto after being displayed. The ends of the conveyer 11 are attached to shafts 6, 18 driven by electric motors 19, 20 respectively put into operation alternatively according to the desired direction of motion of the conveyer. Each motor circuit is provided with a mercury switch which is tilted by the conveyer 11 when the card reaches either the display position or the storage position, so as to stop the motor. Adjustment of the convever frame for the withdrawal of anv card is effected by a hand wheel 29 on'an axially slidable shaft 26, which, however, is held in uncoupled position relatively to the conveyer frame when the main switch 21 controlling the motors 19, 20 is in operative position, by means of an arm on the switch shaft engaging a disc on the shaft 26. The circuit of the motor 19 which moves the cards into displaying position is provided with an additional switch 40, Fig. 8, connected to the plunger 36 so that if the plunger is not properly in engagement with a notch of the rack 35, the motor will not operate. In a modification, movement of the conveyer frame is prevented by a spring-pressed pin while either motor is operating, the pin being withdrawn when a card reaches either extreme position by an electromagnet, the circuit of which is closed by a mercury switch actuated by the card-engaging arms on the conveyer. In a further modification, the conveyer frame is fixed and the cards are stored in radial compartments of a rotary container.

Title: Totalizing counter mechanism for a maximum demand meter
IPC: G01R11/60
Filed: 1953-07-16
Abstract: 737,523. Counting-apparatus. LANDIS & GYR AKT.-GES. July 16, 1953 [July 26, 1952], No. 19800/53. Class 106 (1). In an electricity or other meter having a maximum demand indicator 11 which is periodically reset by (spring) power under manual control and its settings transferred, through a friction coupling 30, 31, to a totalizing counter 23, engagement and disengagement of the coupling is effected automatically by the resetting mechanism, and is independent of the manual control. The indicator 11 drives the coupling member 30 through gearing 16-19, a resetting wheel 20 and a pinion 26 fast with the coupling member 30. The pinion 26 and coupling member 30 are normally freely rotatable on a shaft connected by gears 27-29 with the counter 23, the complementary coupling member, 31, which rotates with the shaft, being held clear against the action of a spring 33 by means of a bell-crank 65. During resetting, a lever arm 62 releases the bell-crank so that the coupling is engaged to transmit the resetting movement of the indicator 11 to the counter 23. Resetting is effected by turning a knob 38 which rotates a spur wheel 37 and winds a spring 34 adapted to drive a shaft 35 to which is secured a cam disc 50. Rotation of the cam disc is normally prevented by engagement.of one of a pair of escapement pins 48, 49 on the disc with a lug 46 on a lever 44, 45. As the knob 38 is turned, cams 41, 42 secured to the spur wheel 37 rock the lever 44, 45 so releasing the cam disc after rotation through one revolution by means of the spring 34 and under control of a retarding mechanism 69, 70. As the cam disc rotates, it rocks an arm 61 fast with the arm 62 to engage the coupling 30, 31 for driving the counter 23. At the same time, the tip 57 of a bell-crank 52 picks up a stud 22 on the resetting wheel 20, carrying the stud up to a fixed stop 59 and itself then rocking clear, so resetting the indicator 11 and driving the counter 23. A further arm 66, rockable with the arms 61 and 62, disengages the meter drive from the indicator 11 during resetting.

Abstract: 394,144. Claw clutches; facilitating changing speed. PULSOMETER ENGINEERING CO., Ltd. and WARREN, R., Nine Elms Iron Works, Reading. July 13, 1932, No. 19823. [Class 80 (ii).] In a claw clutch 14, 15 between the gear box 7 and propeller shaft of a motor vehicle, a balking ring 19 arranged for limited rotation on the driven element 15 has dogs corresponding to those on that element and is surrounded by a two-part friction ring 17 which is encircled by a spring ring 18 and which is caused to rotate with the driving element 14 by reason of slotted arms 16 on the latter engaging projections on the ring 17. The element 14 has a conical part 13 adapted to coact with a fixed brake ring 12 and is moved axially by a fork 21 coupled to a spring-loaded block 26 on an actuating rod 25 coupled to the engine clutch pedal 22. The arrangement is such that the clutch 14, 15 is disengaged after disengagement of the engine clutch and the gear-box shaft 6 is braked. On release of the pedal 22, the brake 12, 13 is released and the member 14 is resiliently advanced towards the member 15, the balking ring preventing engagement of the members 14, 15 until the shaft 6 slightly overruns the propeller shaft, the dogs 14 meanwhile riding smoothly over the plane surface presented by the relatively-displaced dogs of the members 15, 17 under the pressure of a spring 6a. Alternatively, the clutch 14, 15 may be operated independently. The Provisional Specification also states that the balking ring may be operated by free-wheel means instead of frictionally.

Title: Automatic drifting valve for locomotives
IPC: F01B25/00
Filed: 1933-07-17
Abstract: 422,707. Fluid - actuated valves. WOOD, H., 68, Nether Street, Finchley, and TOMLINSON, J., 48, St. John's Park, Blackheath, both in London. July 17, 1933, Nos. 20108 and 29024. [Class 135] [See also Group XXXI] Drifting steam control primarily governed by the motion of a locomotive comprises a valve chamber or casing having inlet and outlet connections for drifting steam, a piston valve having opposed ram areas slidable in said chamber for controlling the passage of drifting steam between said connections, the valve being actuated in the opening direction by an accumulated pressure built up in accordance with the motion of the locomotive and acting on one of the said ram areas, and in the closing direction by steam chest pressure, with or without the assistance of auxiliary spring means, acting on the other ram area, and means for continuously venting the accumulated pressure. In the construction shown in Fig. 9 steam pressure from pipe 14 leading to the engine cylinders acts on piston 5 of valve a<2>, and oil from a pump (not shown) driven by a moving part of the locomotive is supplied through a pipe 3 to the space behind a plunger 4 which it keeps in the position shown. A spring 9 between the plunger and the valve tends to keep the valve in the position shown in which a boiler steam pipe 11 admits steam through an annular passage 13 and past the valve to pipe 14. If the regulator is opened the pressure in pipe 14 acts on piston 5 and closes the valve a2, the spring 9 being compressed. If the locomotive stops, the pressure on the plunger 4 drops, and the pressure of drifting steam on the piston 5 will move the valve and the plunger bodily to the left, and the valve will be closed. The oil pump delivers oil past a non-return valve to the pipe 3 and a spring-loaded byepass valve is provided which delivers to the oil reservoir. When the locomotive stops the oil leaks back to the reservoir past a leak in the byepass valve.
