Title: Improved means for stopping the clocks of electric clock installations
IPC: G04C13/04
Filed: 1929-11-22
Abstract: 335,445. Landis et Gyr Soc. Anon. Nov. 26, 1928, [Convention date]. E l e c t r i c clocks; hand-setting apparatus. - In a stopping device for an electric clock system the master clock movement is disconnected for a definite period at any desired time from the means controlling the production of an e.m.f. in the secondary clocks, these means being operatively connected to the master clock hands. This prevents an e.m.f. in the secondary clocks during the stoppage. The master clock movement, not shown, drives (through a friction coupling 4) wheels 3 to a setting-back hand 1. This hand bears in its rotation clockwise on a pin 9 fixed to a ratchet wheel 8 which is loose on the arbor of hand 1 but is rigid with the first wheel of a train 7 leading to the usual master clock hands 5, 6. Teeth on the ratchet coact with a pin 10 on bell-crank 11 pivoted at 12 so that this bell-crank is oscillated by the teeth and by a spring 13; lugs 14, 15 at one end intermittently releasing a weight-driven fly 16 coupled to an indicator 17 supplying timed alternating current impulses to the secondary clocks 18. Thus normally, hands 5, 6 and the secondaries are driven through hand 1 and pin 9. To set the clock system back, say ten minutes, pointer 1 is swung counterclockwise ten minutes. Thus hands 5, 6 and the secondaries are not driven until at the end of ten minutes the setting-back hand 1 again drives pin 9. A part 21 on ratchet 8 coacts with a wheel 20 coupled to shaft of hand 1 through a friction coupling 19. In a modification a gear wheel corresponding to ratchet 8 drives a commutator which periodically couples the secondary clocks to a battery; in this construction the wheel driving the commutator carries a loosely mounted cam, which, when the setting hand 1 is moved backwards, is actuated by this hand to lock the commutator drive. In a further modification, means are provided which prevent locking of the commutator drive whilst an, impulse is being transmitted to the secondary clocks.

Title: Improvements in or relating to rotary pumps of the outwardly-sliding vane type
IPC: F04C14/22
Filed: 1956-11-22
Abstract: 820,648. Rotary pumps. DESCHAMPS, D. J. Nov. 22, 1956 [Nov. 29, 1955], No. 35801/56. Class 110 (2). In a variable-capacity multiple pump unit of the outwardly-sliding vane type wherein the vanes are disposed radially or in planes parallel to radii, the central rotor is equal in width to the combined widths of the end rotors and the central stator 76 is spring-biased about a common pivot 90 in a direction opposite to that of the end stators 66, 86 thereabout. The stator 76 is rigidly mounted on the pivot 90 whilst the stators 66, 86 are mounted thereon with a small degree of angular play. The outlet port of the central pump is offset 180 degrees from the outlet ports 67 of the end pumps and the vanes 115 of the central rotor are offset relative to the vanes of the end rotors which are in phase with one another. Fuel is discharged from the pump through passages 96, 97, 98 in the pivot 90 and thence to an outlet port 37, part of the fuel being fed through a chamber 91, a filter and an adjustable pressure-reducing valve (see Fig. 11, not shown), to the shaft bearings 41, 42. The capacity of the pump is varied by a valve 160 which is adapted to control the supply of pressure fluid from a conduit 173 to an outlet conduit 191 communicating with a piston-andcylinder unit, see Fig. 6 (not shown), and is adapted to unload said unit through passages 192, 184, 178, 201, as desired, the passage 201 communicating with the inlet side of the pump. The piston varies the eccentricity of the pumps by acting on a shaft 100 which has a limited rotation in any one direction of 45 degrees and is geared to a ported sleeve 180 surrounding the valve 160. The sleeve has a limited rotation of 60 degrees in either direction and the relative movement between the sleeve and shaft 100 automatically permits re-setting of the valve to the desired position necessitated by leakage in the system. Leakage along the valve 160 is recirculated to the inlet side of the pump through conduits 193, 201. Reference has been directed by the Comptroller to Specification 743,088.

Title: Method and apparatus for gas analysis
IPC: G01N7/04
Filed: 1960-10-20
Abstract: 963,197. Gas analysis. E. H. COLEMAN, and G. H. J. ELKINS. Nov. 15, 1961 [Oct. 20, 1960], No. 35931/60. Heading G1B. In an apparatus for continuously analysing a gaseous mixture comprising a number of treatment vessels connected in series with a continuous passage of a stream of gas, different treatment vessels being for removal of different components of the gas mixture whereby the change in volume caused by the removal of the component in the mixture is a measure of the amount of component, the gas stream is initially heated to vaporise any entrained liquid and the first removal stage is for removing vapour from the gas. A katharometer may be connected to the outlet of the last measuring device. A gas mixture from a sampling point is passed through a pipe line, which is heated to prevent condensation therein, to a flow measuring device 11. The device has a vertical conical tube of narrow angle which contains a light bob. The vertical position of the bob in the tube is a measure of the rate of passage of gas. The flow measuring device 11 is enclosed in an insulated cabinet 12 which is maintained thermostatically at a temperature sufficient to vaporize any water contained in the gas, say 105‹C. From the device 11 the gas passes to a treatment column 13. It passes up this column in counterflow to a stream of water for condensing water vapour in the gas, the water running down from a reservoir on top of the apparatus. The gas leaving column 13 passes to flow measuring device 11a. The difference in reading between flow measuring devices 11 and 11a then gives a measure of the water content of the gas mixture expressed as volume of vapour. In calculating the initial water content of the gas mixture, allowance must be made for the water vapour content of the gas leaving the column 13 which is at a known value dependent on the temperature. The gas then passes to the next column, 13a, which removes another component of the mixture, carbon dioxide for example. The content of that component will be measured by the difference in reading between flow measuring devices 11a and 11b. Further components are removed by succeeding columns, each preceded and followed by a flow measuring device. In each of said succeeding columns the gas passes'in counterflow to an aqueous solution of an absorbent or reagent for removing one component of the mixture. Liquid U-trap seals 16, 16a &c. are provided in the liquid outlets from the columns. The movement of gas through the system is maintained by an aspirator or low pressure pump.
