Title: Improvements relating to electric rack striking mechanisms for clocks
IPC: G04C21/08
Filed: 1929-05-11
Abstract: 311,423. Bulle, M. P. Favre-. May 11, 1929. [A Specification was laid open to inspection under, Sect. 91 of the Acts, May 12, 1929]. Striking-mechanism- In striking mechanism of the rack type the rack is returned tooth by tooth during striking by a pawl pivoted eccentrically and driven by an electromotor, means being provided for stopping the motor at the moment the striking is completed. The hour wheel 1 carries the striking snail 2: and a wheel 3 of the minute hand mechanism rotating once per hour, carries two pins 4, 5 for the half-hours and hours respectively. This wheel 3 rotates clockwise, Fig. 1, and the pins on it co-act with the bevelled end of a lever 6 pivoted at 7 and carrying pins 9, 10, 11 which operate lever 12 and pawls 22, 24 respectively. A spring 16 pulls lever 12 counterclockwise of its pivot 13 so that a shoulder 14 on it is held against pin 9. An electrically conducting pin 15 on lever 12 co-acts with an insulated conducting face 18<1> on the striking rack 18 pivoted at 17. Pawl 22 co-operates with a special tooth 19 longer than the outer teeth acting with pawl 24. When the hour pin 5 reaches lever 6 is depresses the end 8 so that pin 9 rocks lever 12 clockwise to withdraw pin 15; shortly afterwards pin 11 removes pawl 24 from the rack teeth and subsequently pawl 22 is withdrawn so that the arm 20 moves up to meet the cam 2, moving a differential distance according to the hour, in the usual way. Shortly afterwards pin 5 wipes past end 8, the pawls 22, 24 return to the rack and pin 15 makes electric contact with face 18<1> to start the motor 29. At the same time a pawl 31 on an arm 32 of lever 6 positively rotates a ratchet wheel 30 on the motor shaft 28 to start the motor in rotation. Pawl 22 is pivoted at 23 and spring connected at 55 with pawl 24 which is eccentrically pivoted at 25 to a wheel 26 driven by worm 27 from the motor 29 so that as the latter is running the pawl 24 is reciprocated up and down to return the rack 18 downwards tooth by tooth to its normal lowest position. At the same time a pin 35 on the wheel 26 (or an opposite cam) actuates the bell mechanism 39, 41, 40, 42 (the latter being the bell) once for each tooth the rack is moved down. As the rack reaches its lowest position the pin 15 moves to the position of Fig, 1, so that an arm 33, moving with lever 12 about pivot 13. moves a bell-crank 34 into the path of pin 35 so that the bell-crank is rocked and its upper end positively arrests the motor 29 by being in the path of a pin 36 on the wheel 30. Modifications for arresting the motor at this moment are (1) a spring on the motor shaft co-operating with an arm on lever 12 and (2) a dog clutch between the motor shaft and the wheel 26, which clutch is thrown out when a pin on or rigid with lever 12 throws out the dog. For the half-hour pin 4 a cam 36<1> prevents the complete raising of arm 20.

Abstract: 966,122. Hydrogen diffusion elements. JOHNSON, MATTHEY & CO. Ltd. March 8, 1963 [April 17, 1962], No. 14810/62. Heading B1L. [Also in Division F2] A hydrogen diffusion element comprises a tube of hydrogen-permeable material in which is located so as to extend along the bore thereof, at least one stiffener whose lateral rigidity is retained under stress of temperature and pressure thus preventing deformation of the tube but permitting passage of hydrogen. The tube may be made of Pd or Pd alloy, e.g. 25% Ag-Pd. The stiffener which may be made of stainless steel or nickel, may be an elongated coil spring, a twisted metal tape, a perforated tube, a plurality of metallic or ceramic rods, a multiplicity of small diameter metal shot or a plurality of intertwined or consecutively arranged wires or tapes. A pervious ceramic rod or tube may also be used as a stiffener and the rod may have a diameter less than the internal diameter of the diffusion tube and be carried by a header mounted in the open end of the diffusion tube. A hydrogen diffusion apparatus, Fig. 2, is constructed out of a number of these diffusion elements 1 closed at one end 2 and containing stiffener springs 3. The tubes are mounted in the base 6 of a cup 5. Gaseous mixtures containing hydrogen enter under pressure at 4d and pass along the tube 4b and into the casing 4. Hydrogen diffuses into the interior of the tubes 1 and passes out through 8. The remaning gas passes out from the apparatus at 4e. In specific embodiments, various temperatures and pressures are exemplified in relation to a stainless steel coil, the highest values being 700 ‹C. and 800 p.s.i.g. respectively. The Provisional Specification discloses the use of glass beads as stiffeners.

Title: Improvements in or relating to automatic release devices
IPC: B64D17/38
Filed: 1953-06-12
Abstract: 716,296. Parachutes for retarding aircraft. FLIGHT REFUELLING Ltd., and MACGREGOR, P. S. June 12, 1953 [June 12, 1952], No. 14863/52. Class 4 [Also in Group XXV] An automatic' overload release device comprises a member 14 to which the load is applied, connected by latch means to a piston 11 which acts on liquid in a cylinder 8, pressure of which is controlled by a relief valve 36, relative movement of the piston and cylinder under action of the releasing load acting to release the latch means. The latch means comprises a socket 13 on the piston rod having a ring of holes 26. A ball 25 disposed in each hole 26 is also partly disposed in a groove 24 in the member 14. The balls 25 are retained in the holes 26 by the rib 19 of a sleeve 18. In operation, when applied to the connection of a parachute (connected at 15 to the member 14) to an aircraft, on the occurrence of a predetermined load acting rightwards on the member 14, the valve 36 is lifted by pressure developed on the liquid by the piston 11. Movement of the piston 11 to the right is thus permitted, and the balls 25 are moved out of register with the rib 19. The member 14 is thereby released. The other side of the valve 36 is connected by a pipe 32 with an air-loaded liquid reservoir 33. A lightly-loaded valve 37 permits flow from the reservoir 33 to the cylinder 8. A slide valve 38 may be operated by a solenoid 39 (under the control of the pilot of the aircraft) to provide unrestricted communication between the cylinder 8 and the reservoir 33. By pushing the sleeve 18 manually inwards against a spring 23, the member 14 may be released without relative movement of the piston 11 and cylinder 8. The piston 11 may alternatively be fixed, and the cylinder secured to the socket 13. The device is universally jointed in an outer member 2 in order that the parachute may align itself correctly in a cross wind. A ball detent 42 however holds the device in its normal position.

The enclosure is exhausted by a tube 6 and may be filled with nitrogen. Coils 7, 8, 9 respectively surround the rods 1, 1<SP>1</SP>, 2, 2<SP>1</SP> and 3, 3<SP>1</SP> of the two contact sets, the magnetic circuits being completed by yokes 10, 11 having bent-over flanges 12, 14 entering the coils and insulated from the rods by low reluctance spacers 13, 15. The coil 9 serves to polarize the armatures and the coils 7, 8 are energized to produce fluxes which assist each other whereby the armatures are held against the rods 1, 1<SP>1</SP> or 2, 2<SP>1</SP> depending on the polarity of the coils 7, 8, the armatures being changedover by reversing the current in the coils 7, 8. In another construction, Figs. 4, 7, the rods 1, 1<SP>1</SP> are embraced by a pair of coils 16, 17 and the rods 2, 2<SP>1</SP> by a coil 18, and a pair of yokes 19, 20 magnetically link the rods 3, 3<SP>1</SP> with the rods 1, 1<SP>1</SP> and 2, 21. In one condition of the relay only the polarizing winding 16 is energized and the armatures are held against the rods 1, 1<SP>1</SP>, the armatures being changed over by energizing the coils 17, 18 to produce fluxes denoted by arrows in Fig. 7. In the construction, Fig. 8, the magnetic circuits between the rods 3 and rods 1, 2 of a number of units 4 are completed by yokes 25, 26. When only the polarizing coil 27 is energized the armatures 5 engage the rods 1, energization of the coil 28 in the same sense as the coil 27 causing the flux from the coil 27 to be diverted from the rods 3 to the yoke 26, and the armatures changeover. According to Fig. 11 a single housing 33 accommodates two change-over contact sets 1,.2, 5 spaced in a direction perpendicular to the plane of the Fig. and situated at either side of a common E-shaped yoke 35, the pairs of rods 1, 2 and 3 being respectively surrounded by coils 36, 37, 38 which also embrace appropriate limbs of the yoke, the relay functioning as described with reference to Fig. 3. The polarizing windings may be replaced by permanent magnets. Specification 631,713 is referred to.

Filed: 1919-06-13
Abstract: 147,334. Kelvin, Bottomley, & Baird, and Field, M. B. June 13, 1919. Indicators actuated by pressure of head of liquid.-Apparatus is provided whereby the plane of demarcation between two non-miscible liquids in a tank, e.g., oil and sea-water in a fuel-tank of a ship, is indicated at a distance. The tank 5 is assumed to contain oil in its upper portion, which is displaced by sea-water entering by the pipe P. Two tubes 3 and 4 are connected at one end with gauge glasses 1, 2 and at the other end with the sea and with the oil in the tank 5 respectively; preferably the pipes are kept adjacent to one another to equalize the temperature conditions. The upper ends of the gauge glasses are provided with valves C', C<2> whereby they may be connected together or to a closed chamber 6. The chamber 6 is provided with a cock 7 communicating with the atmosphere, and is connected to a supply of air under pressure by means of the valved pipe 8. Seawater is first admitted to the chamber 6 through the pipe 3, and is then driven out through the pipe 4 by admitting air under pressure. The gauge glasses 1, 2 are then put into communication with one another at the top, a quantity of air being trapped above the liquid. The difference in level in the two gauge glasses then indicates the difference in head of a column of sea water between the bottom of the tank and the end of the tube 4, and the corresponding column of water and oil actually existing in the tank. A movable graduated scale 10 may be used to measure the difference in level. The scale may be marked to indicate not only the position of the plane of demarcation in the tank, but also the weight or volume of the oil or water or both, in the tank. A single indicating-instrument may be made to serve for a number of similar tanks, or separate instruments with a common chamber 6 may be used if the tanks are dissimilar.
