Abstract: 1301144 Measuring strain; measuring creep UNITED KINGDOM ATOMIC ENERGY  AUTHORITY 19 April 1971 [20 Feb 1970 8393/70 Headings G1N G1M and G1S [Also in Division G4] In an extensometer, particularly for measuring the creep of a specimen 3 in a nuclear reactor core or other hostile environment, a probe 8 moves backwards and forwards between two datum positions A, B on the specimen and the distance  travelled by the probe is measured. The alignment of the gauge probe 8 with datum positions A, B may be indicated by abutment of the probe against shoulders 6, 7 or by a fluidic device (cf below). The probe may be moved by a solenoid 10 acting on rod 9, by the solenoid 10 upwardly and gravity downwardly, by a motor through worm or rack and pinion gearing by a fluid servomechanism or by a piston and cylinder arrangement, and the probe movement may be reversed automatically at datum positions A and B e.g. by means of a fluidic control circuit. The movement of the probe may be measured by a variable reluctance or inductance transducer comprising a coil 11 and a core 10. Alternatively the movement may be measured by a transducer producing a digital output or by a vernier scale arrangement. Fig.2 shows one form of fluidic device for indicating when the probe reaches a datum position. The probe includes a rectangular nozzle 13 to which air or helium pressure pulses are passed. A block 16 with ducts as shown is fitted at each datum position. When the nozzle 13 is just above the datum position as shown in Fig.2, the jet from nozzle 13 passes along channel 18 by wall effect and then along channel 14 in the probe. When the nozzle 13 passes to just below the datum position the jet from the nozzle 13 passes along channel 19 and then along channel 15 in the probe. The switch over of the jet is detected by a differential pressure device connected to channels 14 and 15. The fluidic output may be used to operate visual or audible indicating or recording devices or to control movement of the probe. The blocks 16 may be movable instead of or as well as the probe.

Filed: 1929-03-22
Abstract: 310,027. Servo-Frein Dewandre, (Assignees of Gauch, A. G.). April 21, 1928, [Convention, date]. Fluid-pressure.-In a brake actuated by pneumatic pressure under the control of a pedal connected to the mechanical transmission system of the brakes, the effort exerted on the pedal is transmitted hydraulically or pneumatically to a distributor which controls the communication of the brake-operating cylinder with the source of compressed air or vacuum and the atmosphere. As applied to a compressed air system, the pedal lever 1 mounted on the brake-operating shaft 2 and connected to the piston 16 carries in a casing 3 a series of deformable chambers 4 engaged by the slidable rod 6 of a pedal plate 2. The chambers 4 are connected by tubing 8, 9, 10 to a second series of deformable chambers 11 connected to a rod 18 subject to the action of a spring 19 and carrying arms 20, 21 adapted to engage the rods of valves 22, 23 which control communication of the brake cylinder 15 with a source of compressed air and with the atmosphere respectively. The chambers 11 are disposed in a chamber 13 which is open to the brake cylinder. When pressure is applied to the plate 7, the brakes are applied mechanically through the lever 1, and the simultaneous compression of the chambers 4 increases the pressure within the chambers 11, and when this pressure is sufficient to overcome the pressure of the spring 19 the exhaust valve 23 is closed and the supply valve 22 opened. When the pressure thus established in cylinder 15 and chamber 13 together with that of the spring 19 exceeds the pressure within the chambers 11, these chambers contract, permitting the closure of the valve 22 while the valve 23 remains closed. The pressure applied to the brakes may be graduated as desired by varying the pressure applied to the plate 7. An initial pressure may' be established in the chambers 4, 11. In a modified construction for a vacuum system, the pressure exerted to apply the brakes acts as a pull on a rod connected to chambers such as 4 which are thereby extended and thus create a vacuum in chambers such as 11 which are connected to a slide valve controlling the connection of the brake cylinder to the source of vacuum and atmosphere.

Abstract: 149,391. McNeil, P. E. April 12, 1919. Metal pipes and tubes.- A device for inspecting the interiors of condenser and like tubes to indicate the presence of pitting or other irregularities consists of a series of feelers b arranged preferably in three helical rows in a core a, Fig. 3, surrounded by a casing a<1> connected by a coupling a<2> and pipe c to a combined valve and ejector-device, which can be set to supply compressed air or other fluid to the interior of the casing a<1>, or to withdraw it from the same. The valve member is a rotary cock, or a slide-valve h which, when moved to its extreme left-hand position, connects a supply pipe j through a passage k to the core a. In its other extreme position, the pipe connects to an ejector l<1>, which is connected by passages k, m, and the valve h to the interior of the core a. The feelers k are arranged in holes bored diametrically through the core a, and helical fluid passages a<4> cause the fluid to act on the bases of the feelers to eject them through apertures in the casing a<1>, the outward motion of the feelers being limited by wires d engaging the shoulders of grooves b<1> in the feelers; or in a modified form, Fig. 4, in which a thick cylinder e.fitted with a liner f is bored to receive the feelers, the outward and inward motion of the feelers is limited by moving the liner f axially after all the feelers have been passed through openings in the liner, and the motion of the feelers is limited by the engagement of either end of the slot b<1> with the liner. The liner f is held in position by a screw-plug g. In operation the presence of pit holes, &c., will be detected by the resistance offered to the movement of the device, and an indication of the position and extent of the holes will be furnished.
