Title: Improvements in or relating to pressure exchangers
Inventor: KENTFIELD JOHN ALAN CHARLES
IPC: F04F13/00
Filed: 1961-05-02
Abstract: 936,427. Rotary motors. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. April 6, 1962 [May 2, 1961], No. 15858/61. Class 110 (2). [Also in Group XXVIII] The cells of a pressure exchanger adapted for the production of useful shaft power are rendered variable in volume by mounting the hub 21, Fig. 3, from which the cell walls 20 radiate so as to rotate about an axis 22 offset from the central axis 24 of the cylindrical shroud 23 surrounding the cell rotor. The volume of each cell thus varies between a minimum value which may be zero at position 26 to a maximum value at position 25. Radial walls 23, Fig. 9, are slidably mounted in hub slots and bear against a shroud 75 which is rotated at the same speed as the hub 74 and is supported by rollers 81 within a fixed outer casing 80. In a modification, blades 64, Fig. 8, radiating from an eccentrically mounted hub 65 are surrounded by a cylindrical shroud 67 having inwardly extending end flanges 69 and radial vanes 70 in direct abutment with blades 64 to effect shroud rotation and the spaces bounded by said vanes 70, flanges 69 and shroud 67 are occupied by liquid urged thereto by centrifugal force. The radial variation of the volume of cells 38, Fig. 5, is indicated diagrammatically by axial variation of the length of the cell walls between end plates 39, 40 depicted as having a curved form. Thus, gas in each cell moving from the lowermost position becomes progressively compressed by virtue of the reduction in volume. In operation, hot high-pressure gas is admitted through a port 41 and is exhausted through a port 43 whilst low pressure gas is admitted through a port 42 and is exhausted through a port 44; the port 43 being of less diameter and coaxial with port 41. In a further modification the eccentricity of hub 83, Fig. 11, is such that at one position the volume of each cell is reduced to zero at a position where the hub contacts a sealing black 98 mounted in a recess of a stationary cylindrical shroud 85. The cells defined by walls 82, hub 83 and shroud 85 are open-ended and have flat end plates 88, 89, Fig. 10, provided with high and low pressure inlet ports 90, 91 and high and low pressure exhaust ports 92, 93, each connected to suitable ducting 94 ... 97. In all constructions the high pressure inlet gas is heated in a combustion chamber (not shown).

Title: Improvements in or relating to zero setting mechanism for indicating instruments
IPC: G01D5/04
Filed: 1942-11-11
Abstract: 562,182. Indicating; altimeters. K. D. G. INSTRUMENTS, Ltd., and MACK, F. Nov. 11, 1942, No. 15968. [Classes 106 (ii) and 106 (iv)] In an indicating instrument of the kind in which toothed gear trains whose axes of rotation are fixed, drive a pointer over a scale, zero adjusting means are provided for moving an arm moved by the responsive element, bodily around the fixed axis of a transmission member, while maintaining the driving relationship of the arm with the transmission element without imparting responsive movement to the responsive element, but imparting movement to the transmission member relative to the responsive element. As shown, a sensitive altimeter comprises a battery of capsules 20 actuating a layshaft 21 through a link 24. A sector plate 13 secured to the layshaft drives a gear train, which actuates pointers 15, 16, 17 to indicate the altitude in tens of thousands, thousands a.nd hundreds of feet respectively. Barometric pressure at ground level is indicated by a circular scale 26 through a window in the dial 18. The scale 26 is rotatable by an adjusting knob 42 through shaft 3, and pinions 32, 31, 30 and 28. The pinion 32 also drives pinions 37, 38 and 41 to rotate a secondary frame 19, carrying the capsules, about the axis of the lay-shaft to adjust the zero setting. Normally the shaft 3 is held against axial movement by a grub screw 39, but for adjusting the barometric pressure scale without adjusting the zero setting of the altimeter, the grub screw is released and the shaft is slid upwards to release the pinion 37. The lay-shaft 21 is subjected to the influence of a spiral spring 6 secured to the secondary frame 19. In the modification shown in Fig. 3, the capsule 43 is stationary and actuates an arm 45 on a lay-shaft 46 having a further arm 56 actuating a gear sector 47 driving a pointer 50. The lay-shaft is carried by a secondary frame 54 rotatable in a horizontal plane by the knob 42, so that the arm 56 is moved round the pivot in the gear sector 47 for zero adjustment.
