Patent GB-645639-A (GB)
Title: Torque meter
IPC: G01L3/06
Filed: 1948-07-17
Abstract: 645,639. Rotary transmission dynamometers. ARMSTRONG SIDDELEY MOTORS, Ltd., and VIALE, S. M. July 17, 1948, No. 19244. [Class 106 (ii)] A dynamometer for measuring the torque in a torsionally flexible driving shaft, for example, an aircraft propeller drive shaft 12, comprises a pair of coaxial three-element epicyclic gearings of equal ratios, 40, 41, having a common planet carrier 39. One of the epicyclic gearings 41 is driven by an internally-toothed ring 33 from the driving end of the shaft 12 and the other 40 is driven by an internally-toothed ring 30 attached to a shaft 26 passing through the centre of the main drive shaft 12 to the driven end where it is keyed to the main shaft 12. Both epicyclic sets of gears are thus driven in unison around sun wheels 43, 45, one of which 45, is held fast to the frame, the other being keyed to a shaft 44 passing through the frame and having a quadrant 50 with a clamp 52 for securing a cable 51 actuating the torque indicator. With no load on the shaft 12 the epicyclic gear sets run in unison and in step with no reaction produced at the quadrant 50. When the shaft is loaded the torsion produced causes the driven end and therefore the shaft 26 and wheel 30 to lag behind the driving end set, causing the quadrant 50 to rotate partially proportional to the torque set up. Under conditions of over-drive, e.g. windmilling of the propeller, a movement of the quadrant 50 takes place in the reverse direction and can be indicated on the same instrument. The movement of the quadrant 50 may be utilized to drive electrical or other means for remote indication or to control the power source or operate a switch in conditions of reverse torque. Specification 632,609 is referred to.

Title: An improved manufacture of fuel gas
IPC: C10J3/46
Filed: 1949-07-21
Abstract: 665,781. Generating and enriching water gas; gaseous mixtures. ARNOLD, J. C., (Standard Oil Development Co.). July 12, 1950 [July 21, 1949], No. 19258/49. Classes 55 (i) and 55 (ii). Fuel gases of high thermal value are continuously generated by contacting water gas in a fluidized bed at high temperature and pressure, with powdered carbonaceous material to which has been added an iron oxide catalyst, methane being formed in the bed by combination of a proportion of the carbon monoxide and hydrogen in the water gas, the latter being generated by gasifying the powdered carbonaceous material from the methane synthesis zone in the form of a fluidized bed in a second zone by a gasifying agent including steam. The apparatus consists of a methane synthesis chamber 1 connected to a water gas generating chamber 2 by a gas transfer pipe 9 and coke transfer line 5. Finely ground coal or coke with an admixture of from 0.1 to 5 per cent of an iron ore catalyst, is fed to chamber 1 from a hopper 3 which can be pressurized to 100 to 600 pounds per square inch, the pressure in chambers 1 and 2. The material is fluidized at from 1100- 1300‹ F. by water gas generated in chamber 2 and flowing up through pipe 9, the water gas, with an increased content of methane, discharging through line 15. If coal is the raw material, carbonization occurs in chamber 1, the distilled volatile matter mixing with the outlet gas. Coke is withdrawn through line 5 and passed into chamber 2 where it is converted into water gas by admission of fluidizing steam from a line 7. To supply the heat requirements, oxygen for partial combustion is admitted through a line 8. Ash is withdrawn from chamber 2 through a line 10, a portion being recirculated through line 11 to be mixed with the raw fuel since it still contains the catalyst. Instead of using oxygen, the heat required for the water gas reaction may be supplied by withdrawing coke from chamber 1, partially burning it in a separate combuster and returning the thus heated material to chamber 2, Fig. 2 (not shown). In an example, a water gas composed of 45 per cent carbon monoxide and 55 per cent hydrogen was passed through a fluidized bed of coke containing 2.2 per cent of hematite, at 250 pounds per square inch and 1200‹ F. The product gas contained 10.2 per cent carbon dioxide, 36.8 per cent carbon monoxide, 36.8 per cent hydrogen and 16.2 per cent methane.

Title: Pressure relief means
IPC: H01H33/56
Filed: 1964-05-11
Abstract: 1,026,435. Valves. S. & C. ELECTRIC CO. May 11, 1964 [March 9, 1964], No. 19518/64. Heading F2V. [Also in Division H2] A pressure relief means suitable for use in circuit breakers comprises, in the embodiment shown in Fig. 2, a rupturable copper diaphragm 63 located at its outer periphery between a support ring 70 and an exhaust tube 61, the diaphragm being normally maintained in the position shown by means of strain wires 85 located between lugs 88 and a connecting member 89, and acting on the diaphragm via an adjusting plate 78, a ball 76, a jack screw 74 and a pressure plate 73. Secured to the diaphragm is a head 99 of a bolt 98, which bolt carries a diaphragm piercing means 93 and a piston 103. The outlet from the housing 53 is close d by a cover 108 held in place by a spring 111. The pressure within the housing acts via the diaphragm on the strain wires and on reaching a predetermined value causes the latter to break, thereby allowing the diaphragm to evert and also allowing the diaphragm piercing means to pierce the diaphragm, thus permitting the escape of gas, which escape results in a pressure difference across the piston, thereby causing it and the cutter to be ejected through the diaphragm and, along with the other separated parts, through the outlet of the housing 53. In the alternative embodiment shown in Fig. 9, excess pressure causes the diaphragm 41 to enter the recess 116 and this in turn causes the tube 123 to move, along with the disc 125. The movement of the disc fractures the strain-sensitive portion 131 of a bolt 133 and thereby releases a diaphragm cutter 136 which is urged to the right by a spring 137 to puncture the diaphragm.
