Title: Improvements in or relating to displacement measuring devices
IPC: G01L1/22
Filed: 1966-08-01
Abstract: 1,088,219. Measuring displacement electrically. TRANSARC Inc. Aug.1, 1966 [Aug.6, 1965], No.34425/66. Heading G1N. Linear or angular displacement is measured by cementing a strain gauge to a thin steel tape which is moved over a pulley or other curved guide. In one embodiment, for measuring strain of a specimen undergoing tensile testing, movement of the specimen is transmitted by rod 51 to a steel tape 41 mounted on pulleys 33, 34. The tape carries two resistance strain gauges one of which is visible at 42, the other being on the far side of the tape so that as the rod 51 is moved downwards this strain gauge is pulled on to pulley 33 whilst gauge 42 moves off the pulley. The two strain gauges form two arms of a bridge to which a millivolt recorder or cathode ray oscilloscope is connected. In modifications, the tape may be moved by rack and pinion, Fig. 9 (not shown), may carry four strain gauges, Fig.4 (not shown); may have a spring return instead of being in a continuous loop. Figs. 12, 14 (not shown), may have a counter-weight and slide over a stationary, curved guide, Fig. 3A (not shown), or the tape may be moved by rotation of a pulley to which it is secured, Figs.10, 11 (not shown).

Filed: 1928-11-24
Abstract: 322,088. Petrie, D., and Conn, M., (trading as Petrie & Conn), and Pietkiewicz, Z. Nov. 24, 1928. Delivery of articles stored in piles. - In a machine of the kind in which articles are delivered by a recessed drum, an ejecting device arranged in the recess ejects the article when the drum is oscillated. As shown, a drum 5, Fig. 5, mounted on trunnions 6, 7 below the magazine 2 is formed with a diametral opening 12 on which is pivoted a tray 14 which supports the lowest article 3 and has a depending portion 16. When the drum is moved, by a handle 18, to delivery position, the portion 16 engages a lug 53 and rocks the tray to eject the article. In a modification, Fig. 9, the drum 5 has a diametral slot 55 at each side of which is fitted a lug 56 to support the article 3. A link 58 pivoted at 59 in a recess 57 in the drum carries a projection 65 and is guided by a pin and slot 61, 60. When the drum is oscillated, the link 58 is raised and the projection 65 enters the slot 55, ejecting the article. A spring 62 returns the link and drum to inoperative position. According to the Provisional Specification, the tray may consist of a counterweighted pivoted plate, or, in the modified form, the link may operate a block slidable in the diametral slot. Coin action, mechanical-connection and multiple-coin.-Tbe drum is locked by a pawl 21. Fig. 7, on a rock shaft 22 engaging a notch 20<2> in a wheel 20 on the trunnion 7. The pawl is normally held just clear of the notch by a screw 20', but engages it on initial oscillation of the drum. The shaft 22 extends behind the drum and carries at its other end a finger 30, Fig. 8. Coins, two in the case shown, fall from a shoot 29 edgewise into a pivoted carrier 25. When the drum is oscillated, a cam 24 on the trunnion 6 engages and rocks the carrier 25, so that the upper coin 51 engages the finger 30 and rocks the shaft 22, holding the pawl 21 clear of the notch 20<2>. The coins are released when the carrier clears a plate 28. A second notch 20<3> in the wheel 20 prevents partial return of the drum and fraudulent abstraction of an article. A plate 54 at the upper end of the carrier 25 prevents jamming of the machine should a coin be inserted while the carrier is out of the vertical position. The machine is provided with a coinselector device of known form. Coin-slit closing-devices.-When the magazine is nearly empty, the arm 44 of a bell-crank lever 46. Fig. 7, is allowed to move in under action of a spring. This moves a link 47, allowing an obstruction to move behind the entrance slit of the coin shoot.

Abstract: 851,754. Nuclear reactors. BABCOCK & WILCOX Ltd. Nov. 14, 1958 [Nov. 15, 1957], No. 35615/57. Class 39(4). [Also in Group XXIX] Steam generator feed-water system. The coolant from a nuclear reactor 10, Fig. 1, flows through superheaters 18, 19, evaporators 16, 17 and economisers 14, 15 and returns to the reactor by a conduit 12 in which is a circulating pump 13. The high-pressure economiser 15, which receives feed water from a pump 40, delivers hot water to a boiler drum 41 via valve means 43, the water from the drum passing through the high pressure evaporator 17 and the vapour in the latter returning to the drum 41. Vapour from which water has been separated in the boiler passes to the high-pressure section of a turbine 28 via the high-pressure superheater 19 and a conduit 47 ; a generator 30 is driven by the turbine and the exhaust expands in a lowpressure section of the turbine before entering a condenser 31 provided with a pump 32 by which condensate is supplied to the pump 40 whilst additional water is supplied to the system by a pipe 36. A similar low-pressure circuit comprising a pump 20, economiser 14, valve means 23, boiler drum 21, evaporator 17, conduit 27 and superheater 18, is also connected to the turbine 28. Feed water level and steam flow control. Feed water flows to the drum 41 through the valve means 43, which latter comprises of a valve 50, Fig. 2, actuated by a positioner 51, and a water level recorder 52 is connected to the drum and controls a valve 55 that determines a first air-pressure supplied through a conduit 58 to a differential relay 59. The pressure drop across an orifice 67 in the conduit 47 is conveyed to a steam flow-meter 60 connected to a valve 61 controlling a second air-pressure fed to the relay 59 by a conduit 64. The difference between the first and second pressures is led by pipes 69, 70 and a selector 71 to the positioner 51, the latter being operated by the difference between a constant air pressure supplied by a pipe 68 and that in pipe 70 ; the selector 71 provides for manual actuation of valve 50. Valve means 23 is similarly operated. Upon a sudden fall in steam flow from the superheater 19 such as may occur on " tripping out " of the generator 30, a pressure rise is experienced in drum 41 resulting in a collapse of steam bubbles with a consequent drop in water level which opens valve 55 and tends to cause an increased flow through valve 50 but such a fall in steam flow increases the opening of valve 61 so limiting the opening of valve 50 and preventing surging of the feed water. The converse occurs with a sudden increase in steam flow. In a modification valve means 43 is subject to control by both water level and temperature of the coolant at the reactor inlet as detected by thermocouples ; the valve means 23 may also be subjected to similar control characteristics or to water level only.
