Title: Improvements in or relating to the measurement of fluid currents
IPC: G01P5/02
Filed: 1960-11-25
Abstract: 923,418. Measuring electrically. PECHINEY COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES. Nov. 25, 1960 [Nov. 27, 1959], No. 40579/60. Class 40 (1). [Also in Groups XX and XXIX] In a system for measuring the speed and direction of flow of a fluid current, a hollow sphere 1, Fig. 1, is mounted by support member 3 on a gimbal suspension 5, the support member being maintained in a vertical position in the absence of fluid currents by counterweight 8 which is adjustable in order to vary the sensitivity of the device. The motion of the sphere under the influence of fluid currents is determined by measuring the displacements of points 9 and 10 of the gimbal suspension by means of pointers 13 and 14 and their co-operating scales. Alternatively, the pointer and scale may be replaced by a core moving relative to a coil in order that the measurements may be electrically signalled to remote indicating apparatus. In such a case the readings of a compass built into the apparatus may also be transmitted, if the orientation of the detector is not known or is liable to alteration. In the electrical signalling system of the described embodiment the positions of the cores in the coils determines the frequencies of two oscillators to signal the displacement of the detector in two co-ordinate directions whilst a mask attached to the compass co-operates with a lamp and photo-cell arrangement which controls the frequency of a third oscillator to signal the orientation of the device.

Filed: 1972-09-04
Abstract: 1447617 Expandable mandrels; friction clutches KODAK Ltd 18 Oct 1973 [4 Sept 1972] 40986/72 Headings F2U and F2C A fluid operated expanding mandrel, for supporting and driving a web rewind core (not shown), while permitting relative slip, has friction pads 7, each comprising a segment 9 of friction material bonded to a metal member 10 with flanges engaged within a T-shaped slot 6, thereby limiting the radial travel, and at the inward limit ensuring that the friction face of pad 7 remains proud of the surface of shaft 1, so that the core cannot come into direct contact with the shaft. Operating fluid is conveyed by an axial bore 2 to intersecting radial bores 4, in which there are plungers 3, each with a seal ring 5. Spacer plate members 8, shaped to prevent their radial movement, are located in the T-slot 6 between the pads 7. A closure member 12, in a widened slot region 11, facilitates assembly of items into the T-slot 6. In operation, the fluid pressure and the speed of rotation of the mandrel may be controlled in relation to the rate of web feed in such a manner that continual relative slipping occurs between the mandrel and the bore of the rewind core as the web builds up on the core. An electrical system which may be used for effecting such control is disclosed in Specification 1,447,618. In alternative embodiments, the mandrel may be used as a clutch or a brake on the core of a web supply roll.

Title: Fuel systems for gas turbine engines
Inventor: WARNE EUGENE HAROLD
Filed: 1966-09-16
Abstract: 1,206,944. 944. Gas turbine engine fuel systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Dec.14, 1967 [Sept. 16, 1966], No. 41474/66. Heading F1G. A gas turbine engine fuel system comprises an engine-driven positive displacement pump, an outlet passage from the pump, a throttle in the outlet passage for controlling fuel flow to the engine a further engine-driven pump in the outlet passage arranged between the first pump and the throttle, the further pump being of a kind in which its delivery pressure is a function of its speed, a device which is responsive to changes in the pressure drop across the throttle, the device being arranged to control the rate of spill of fuel from the outlet passage at a position downstream of the first pump but upstream of the further pump, and means responsive to air pressure changes in the compressor of the engine for varying the response of the device and a manually operable control for the throttle. The fuel system shown comprises a gear pump 10 followed by a centrifugal pump 14, both driven by the engine, supplying fuel to the burners via a throttle 13 and a shut-off cock 15 which are actuated by an electric motor 25 under the control of an apparatus 26 having a manual control lever 27 and into which are fed electrical signals related to engine speed and engine temperature. Fuel is spilt from a passage 29 to a drain 36 via a valve 35 controlled by diaphragms 31, 32 subjected to the pressures upstream and downstream respectively of the throttle 13. Before being applied to the diaphragm 31, the upstream pressure is modified by being applied to a fluid potentiometer comprising an adjustable restrictor 47a and a knife edge 46 under the control of opposed capsules 39, 40. Capsule 40 is evacuated while capsule 39 is connected to a fluid potentiometer 42, 43 which is connected between the upstream and downstream sides of the engine compressor. When the maximum allowable value of the compressor downstream pressure is reached, it acts through a capsule 51 to open an air escape valve 50 to reduce the pressure applied to the capsule 39, whereby the valve 35 reduces the fuel delivery to prevent further increase of the downstream pressure. When the engine reaches a predetermined speed, the pressure developed by the pump 12 becomes sufficient to open a valve 55 in parallel with the knife edge 46 to permit an additional spilling of fuel.

Abstract: 1483207 Suction collection system SORENSON RESEARCH CO INC 27 Sept 1974 [23 Oct 1973] 42158/74 Heading A5R An aseptic suction collection system comprises a cannister 20 containing two flexible plastics reservoirs, a first reservoir 34 for collecting liquid and a second reservoir 44 communicating with the first, a rigid plastics cover 26, with an engaging flange 28, which forms one end of the first reservoir and has an inlet 32 connected to a collecting tube 82, an outlet 30 connected to a vacuum line 80 and a filter 36. The communication between the two reservoirs is by two sleeves 42, 46 in telescopic relationship, with a plug 50, Fig. 1, or 51, Fig. 3, fitted into sleeve 42, the plug having a larger diameter cylinder, an intermediate diameter cylinder 62 and diametrically placed extension 58 having small projections 60 at its end adjacent the intermediate cylinder 62 to prevent contact of sleeve 42 with said cylinder, maintaining thus a fluid flow channel, and projections 59 at its other end for engaging the inner surface ,of sleeve 42. In use blood is sucked in through tube 82, filtered by filter 36 and collected in the first reservoir, the air in the second reservoir being simultaneously sucked out, preventing inflow of blood; when the tube 82 starts to suck in air the pressure in reservoir 34 will increase and start to force liquid 86 into the second reservoir where it is then aseptically contained. When the two reservoirs are pulled apart the plug, 50 or 51, is pulled up into sleeve 46 to automatically seal the second reservoir 44. Inlet 22 in the side of cannister 20 creates a vacuum around the reservoirs preventing their collapse. There is a sealed inlet 64 in reservoir 44 to allow subsequent transfusion of the collected blood. In a modification to the plug 51, Fig. 4 (not shown), the extension 58 is replaced by a smaller diameter cylinder and inlet holes 48, Fig. 1, are provided in sleeve 42 adjacent its end.
