Title: Apparatus for measuring the force on a body due to fluid pressure
IPC: G01L9/00
Filed: 1965-12-16
Abstract: 1,125,448. Measuring fluid-pressure electrically. C.M.R. PALLIS. Dec. 12, 1966 [Dec. 16, 1965; March 8, 1966], Nos.53360/65 and 10002/66. Heading G1N. The component of force in a selected direction on a body due to variable fluid-pressure is measured by capacitative transducers in a bridge circuit and may be applied to the measurement of the mass of liquid or granulated material in a tank or the force on an aerofoil in a fluid stream. In one embodiment, Fig. 1, the mass of liquid in an enclosed tank 10 subject to variable acceleration (vector G) is measured by lining both the floor and the roof of the tank with a capacitor web comprising a pair of metal foil electrodes 12 and 13, spaced apart by a rubber matrix 14 and enclosed in a flexible insulating film 15. The interiors of the rubber matrices are linked together and to the interior of the tank by vent pipes 16, 17. The pipe 17 is closed by a zero-stiffness diaphragm or bladder 18. The two capacitor webs from adjacent arms of a bridge circuit, Fig. 4 (not shown), having fixed capacitors in the other two arms. The bridge is energized by an alternating voltage proportional to the reciprocal of the vertical component of the acceleration to which the tank is subjected. Acceleration is measured by an accelerometer 24 of unspecified type. It It is shown that the resultant output signal from the bridge is proportional to the mass of the liquid in the tank. Compensation for changes in flow gradient may be made by cutting holes in the foil electrodes so as to locally grade the capacitor web. Similarly, compensation for openings in the tank which cannot be lined with the capacitor web may be made by surrounding the area with an annular capacitor of increased effectivness Fig. 3 (not shown). In a first modification, applicable when the roof of the tank is not wetted, the capacitor web on the roof is replaced by either a device responsive to the external pressure acting on the liquid or by a manually pre-set signal device. In a second modification, applicable when the acceleration is due solely to gravity, the accelerometer 24 may be replaced by a device providing a signal proportional to the angle of tilt of the tank, or if the tank is fixed the accelerometer is omitted altogether. In a second embodiment, Fig. 5 (not shown), the floor of the tank is lined with strip shaped capacitors connected in parallel. Each capacitor comprises a compressible oval tube forming one electrode 2 within which is mounted an elongated, cruciform structure the horizontal arms of which form the other electrode. In another embodiment, Fig. 6 (not shown) the pressure on an aerofoil due to a stream of fluid is measured by covering the upper and lower surfaces with capacitor webs and comparing their values.

Filed: 1967-11-30
Abstract: 1,176,738. Controlling reactors. NUCLEAR POWER GROUP Ltd. 28 Nov., 1968 [30 Nov., 1967], No. 54568/67. Heading G6C. A control rod actuating system comprises means for inserting one or more rods of neutron absorbing material into a reactor core by means of an external force produced by a falling weight or weights, the force being transmitted to the rod or rods by a pulley and endless rope or chain system. In the embodiment described, the control rod (not shown) rests on a shock absorber 12, e.g. a roll of dimpled metal sheet, which in the fully withdrawn position, rests in turn on a stepped portion 11a of a vertical liner tube 11 which passes through the floor 4 of a concrete pressure vessel. The control rod actuating system comprises falling weights 13, 14 which act through a pulley and endless chain system to exert an upward force on the control rod. The pulley and endless chain system comprises two endless chains 15 and pulleys 16, 17, 18, 19. The drive to the pulleys is through a bevel and wheel drive 20, 21, wheel 21 driving pulley 17 directly and pulley 16 through a gear-wheel 22. In contact with the shock absorber 12 is a push rod 23 the lower end of which is supported on the endless chains 15 by a link 24. The drive to the bevel 20 is through a magnetic clutch and when as a result of a fault condition the clutch is deenergized, the bevel becomes disconnected from the drive motor and is free to rotate independently of the motor. The weights 13, 14 then fall under the action of gravity and accelerate the control rod into the reactor core. The chains 15 pass through both the weights 13, 14 and are secured to the lower weight 14. When the weight 13 reaches a step A in the tube 11 its fall is arrested and the control rod continues to move upwards under the influence of the smaller weight 14 until this is arrested by a further step B in the tube 11. The weight 14 may be such that it just overcomes friction and the weight of the control rod, the push rod 23 and the shock absorber 12 so that the control rod moves at uniform speed after the weight 14 is arrested. The actuating mechanism can be sealed off from the reactor by raising the weights 13, 14 to a position such that the push rod 23 is below a valve 25 which is then closed and the lower part of the tube 11 depressurized. The actuating system can then be removed for maintenance or other purposes. The control rod is removed from the reactor by a charge machine operating above the reactor core.

Abstract: 561,127. Liquid pressure engines; soot blowers. AUTOMOTIVE PRODUCTS CO., Ltd., and BROWNLEE, R., I. Dec. 14, 1942, No. 17773. [Class 69 (ii)] [Also in Group XXVIII] In a liquid pressure remote control system in which a motor 10 operates trip valves 24, 25 to effect reversal, short strokes are obtained by feeding small predetermined quantities of liquid to the motor through a measuring device 110. The motor may operate a retractable soot blower which can be caused to effect a full approach movement a predetermined number of short reciprocations and a full retracting stroke for normal operation. A pump 32, Fig. 1, supplies pressure liquid through a normally open valve 35, change-over valve 37a, reversing valve 39a and line 29a to cylinder 20. At the end of the stroke, valve 25 is tripped and pressure liquid byepassed through line 26a to actuate a piston 72, thereby moving reversing valve 84 to the left and connecting line 29a to the reservoir. Pressure now passes through line 28a and motor 10 is reversed until it trips valve 24 and again actuates valve 84 in the opposite direction. Each movement to the right of this valve moves a pivoted portion 51 of the change-over valve to the right through ratchet and pawl mechanism 101, 102. After a predetermined number of movements the portion 51 is moved bodily, thereby reversing the positions of valves 61 ... 64 and connecting the pressure supply to the change-over valve of the next blower, motor 10 being then connected to reservoir. To effect short strokes, a valve 35, connecting the ends of a measuring cylinder 110, is closed and pressure liquid then moves a piston 112 to the left and delivers a measured volume of liquid to the line 36a thus moving the motor about one-third stroke. At the end of the movement of piston 112 a valve 118 is tripped and pressure liquid supplied to piston 72, thereby reversing valve 84. The valve 35 is normally held open by a spring- loaded bar 124 which is withdrawn by a linkage carried by the valve 84 when a fulcrum carried by the member 51 is in the path of the linkage. This fulcrum is withdrawn from its operative position after the desired number of short strokes by a stop on the ratchet mechanism 100. A number of measuring cylinders may be connected in series with the last one only carrying a valve 118. Hence, by cutting out one or more of the cylinders, the volume of 'liquid supplied to the motor may be. varied. A number of byepass valves 35 may be connected in series, each coupled with one or more change-over valves so arranged that when any one closes, liquid flows into the measuring cylinder. Rotary motors may replace the reciprocating motors. Specifications 538,659, [Group XXVIII], 538,879 and 538,882 are referred to.
