Title: Improvements relating to apparatus for detecting leaks in gas flow ducts
Inventor: JAMESON GEORGE ROBERT KENNETH
IPC: G01M3/28
Filed: 1958-10-14
Abstract: 859,490. Detecting leaks. A.E.I.-J. THOMPSON NUCLEAR ENERGY CO. Ltd. Oct. 1, 1959 [Oct. 14, 1958], No. 32786/58. Class 99(2). An apparatus for detecting leaks in a gas flow duct 2 comprises a Venturi tube 4 mounted in the duct in alignment with the gas flow, a restriction 3 on the downstream side of the Venturi, and warning means responsive to the ratio of the pressure P2 in the Venturi throat 5 relative to the pressure P1 on the upstream side of the Venturi, which indicates a leak when this ratio varies from its initial value. As shown in Fig. 2, the warning means consists of a piston with ends 7, 8 and biased by a spring 9. When the pressure ratio becomes low due to a leak in the duct the piston moves so as to close electrical contacts 15 to thereby operate apparatus serving to cut off gas feed to the pressurised vessel 1 connected to the duct or in other cases closing a supply valve at the duct entrance. For preventing spurious trips of the apparatus when P1 is high, a bellows 19, connected to the outer contact increases the gap between the contacts at high pressures. The Venturi tube may form part of the duct. As shown in Fig. 4, a leak port in which needle 20, operated by bellows 21, is located provides a means for keeping the ratio of the pressure in cylinder 12 to the pressure P2 linear.

Title: Improvements in or relating to electron discharge apparatus
IPC: H01J31/04
Filed: 1947-12-12
Abstract: 663,837. Cathode-ray tubes. WESTERN ELECTRIC CO., Inc. Dec. 12, 1947 [Dec. 13, 1946], No. 32803/47. Addition to 637,820. Class 39 (i). [Also in Groups XXXV and XL (c)] In a signalling system as claimed in the parent Specification in which the amplitude of a complex wave is sampled at recurrent intervals, an electron beam of a cathode-ray tube is deflected in one direction by plates 33, Fig. 1, to an extent in accordance with the amplitude of each sample to select a path and is swept along that path by sweep circuit 34, and a coding element 26 comprising a plate with rows of apertures formed therein produces pulses at the target 25 representing by a permutation code the sampled signal wave amplitude, a grid electrode 28 is arranged in front of the coding element 26 and is connected by a feed-back path comprising amplifier 44 to the deflecting plates 33 so that as a result of current flowing to grid electrode 28 a feed-back voltage is applied to plates 33 to hold the beam in the selected path. The coding element 26 may have five parallel rows I ... V of apertures 27 therein, as shown in Fig. 2, and the grid 28 comprises a number of parallel wires aligned with the apertures in the coding element and secured to a frame 28. Members 26, 28 are secured together by insulating studs 32. The signal sample is applied to plates 33 via condenser 42 and leaks slowly away through resistor 43 so that the beam, deflected initially to a point between two grid wires 31, moves to contact a wire 31 so that the feed-back to plates 33 is varied and consequently the beam is held against the grid wire for the duration of the sweep. The beam is thus held in its correct path during a sweep despite slight variations in the input signal or misalignment of the grid wires with the direction of the beam sweep or disturbances in the beam sweep system. To avoid coding errors, the beam may be blanked and the feed-back circuit closed or the feed-back circuit opened and the beam left on until the plates 33 are energized. In a modification (not shown) a seven-digit coding element may be used. Specifications 630,094, [Group XL (c)], and 633,838 are referred to.

Title: Improvements in or relating to swash-plate mechanism for engines, pumps and the like
IPC: F01B3/00
Filed: 1921-12-15
Abstract: 184,740. Pettingill, V. I. P. M. Dec. 15, 1921. Driving-gear; engines with main shaft parallel to cylinders.-A driving mechanism for fluid-pressure engines and pumps, but particularly adapted for internal-combustion engines, comprises a swash-plate which is adjusted, to vary the piston clearance, by selective means including a differ. ential gear carrying brake drums. The engine has oppositely-moving pistons 7, connected to rings 9 mounted on swash plates 14 adjustably secured to a central shaft 6. Each swash-plate carries a trunnion block 15 free to slide in an inclined groove 16 provided in a guide block 17 fixed to the central shaft. Extending through the shaft is a right and left hand screw threaded rod 20 engaging nuts 21 sliding in slots 22 the nuts being secured to the swash-plates. Movement of the screwed rod relatively to the shaft alters the axial positions of the swash-plates the inclination of which is simultaneously varied by the trunnion blocks sliding in the slots 16. Mounted at one end of the shaft 6 is a differential gear comprising wheels 24 secured to and rotating with the shaft, and a pair of loose wheels 26, 27 one of which, 27, is fixed to the central rod 20. The wheels 26, 27, carry brake drums adapted to be engaged by shoes 30 pivoted to a bracket 28. The arm 36 supporting the shoes its secured at 35 to the lower end of a hand lever 32 connected by a rod, not shown, to one of the parts of the swashplate mechanism. Movement of the lever 32 holds stationary one or other of the wheels 26, 27 and the relative motion thus obtained between the shaft and the central rod adjusts the swashplates in a direction dependent upon the wheel selected to be held by its adjacent shoe. When a swash-plate is moved into either of its extreme positions the rod connecting the hand lever automatically releases the brake shoes thus leaving the screw 20 free to rotate with the shaft. To prevent rotation of the ring 9 upon the swashplate the ring is secured to a second outer ring 40 mounted to turn about trunnions 44. The swash-plates have heavy rims for balancing.
