Filed: 1928-08-02
Abstract: 313,481. Soc. L'Auxiliaire des Chemins de Fer et de l'Industrie. June 12,1928, [Convention date]. Feedwater, heating.-water to be heated is mixed in a chamber 20 with steam entering at 22 and is passed into a following chamber 21, through a water seal 25, both chambers being substantially closed and adapted to contain steam under pressure. Compartment 30 is under atmospheric pressure and is connected by a pipe 9 with the suction side of the feed pump. Hot water is delivered from chamber 21 to compartment 30 through a discharge tube 2 with a valve or other device 5 so disposed in the tube that one face is subjected to a pressure which depends on the steam pressure and the heads of water in the tube while the other is subjected to a substantially constant pressure added to the steam pressure. As shown, the constant pressure is that of the column of water in the tube 3, but it may be provided by a spring. By this means water is discharged without loss of steam. Specification 290,598 is referred to.

Title: Improvements in or relating to linear dimension gauges
IPC: G01B5/00
Filed: 1946-07-30
Abstract: 635,122. Linear-dimension gauges. BROWN & SHARPE MANUFACTURING CO. July 30, 1946, No. 22659. Convention date, Aug. 1, 1945. [Class 106 (ii)] [Also in Group XXXVIII] In a linear dimension gauge movement of the gauging member varies the strain in an element correspondingly, the element having electrical resistance type strain gauges bonded thereto and connected in a circuit for indicating the strain and hence the gauging member movement. As shown, the element to be gauged is supported on an anvil 12 and contacted by a feeler 16 slidable in an overarm support 14 mounted for vertical adjustment relative to the base 10, by means of a screw 22 and nut 26. Vertical movement of the feeler 16 in the support 14 is limited by a set-screw 36, and a spring 32 biasses the feeler downwardly, the spring pressure being adjustable at 40. Rigid with the support 14 is a block 56 having an arm 64 to whidh an arm 60 is pivoted by means of a leaf-spring 62. A flat plate 50 carrying two resistance-strain gauges on each face is held in jaws 52, 54, in the block 56 and arm 60 respectively. The arm 60 is biassed upwardly by a compression spring 68 and bolt 70 and its lefthand end engages within and moves with a U-shaped portion 34 of the feeler. The upward movement of arm 60 is limited by an adjustable stop 76, and a further adjustment is provided by a knob (not shown) by which a shaft 94 may be rocked between limits determined by a radial shaft projection 98 co-operating with an adjustable stop-plate 100 and a fixed stop 99. The shaft 94 carries an eccentric co-operating with a screw-stop 92 whereby the arm 64 may be strained downwardly relative to the block 56 to move the pivotal point of arm 60. The limited movement of the feeler 16 is such that the plate 50 always remains substantially strained, as shown, whereby the pressure exerted on the work by feeler 16 remains substantially constant. The four strain resistors are connected in the arms of an A.C. bridge, Fig. 6, an adjustable portion of the out-ofbalance voltage across R3 being amplified at A and fed through a transformer T3,1 and rectifier ring RX to a centre zero instrument M. The rectifier ring is also fed with a reference potential,. from the oscillator supplying the bridge, through a transformer T2,2 so that the meter M, in known manner, indicates both the magnitude and sense of the bridge unbalance. The gauge is used as a comparator, the various adjustments being made to produce zero deflection of meter M with a standard piece in the gauge, the meter then indicating deviation from the standard plus or minus, of test pieces subsequently gauged. In a modification, Fig. 4 (not shown), the plate carrying the strain resistors is mounted as a vertical cantilever, the free end of which is deflected by a spring to urge the gauging feeler into contact with the work. In another modification, Fig. 5 (not shown), the plate is tensioned longitudinally by a Bellville spring which biasses the feeler into contact with the work.

Filed: 1937-08-18
Abstract: 483,958. Aerating liquids ; pressureregulating valves. COHEN, W. Aug. 18, 1937, No. 22684. [Class 14 (i)] [Also in Group XXIX] An apparatus for whipping and dispensing cream and the like comprises a gas reservoir, a cream container, and a gas-control valve which is adapted to close automatically when a certain pressure has been established in the container. The gas reservoir 5 containing nitrous oxide, is connected, by a valve 9 and a pipe 34 with a check valve 42, to the cream container 40 which includes a siphon tube 45, spout 48, and manual valve 50. The valve 9 comprises a manual valve 8, a passage 13 never wholly closed by a valve 15, and a passage 27 connected to the pipe 34, to a safety valve 30, and to the space below a piston 22 in a chamber 21. Normally, a spring 20 presses the piston downwardly, so that its stem 18 holds the valve 15 downwardly against the pressure of a spring 16. When the valve 8 is opened, gas passes, by the passages 13 and 27, to the container 40 to whip the cream and establish a discharge pressure. As the pressure rises, the piston 22 is raised, allowing the valve 15 to rise until it engages a seat 62 and closes the passage 27. At the same time, the projection of the piston stem 18 above the valve casing indicates to an operator that the desired pressure has been attained.

Abstract: 803,548. Combustion apparatus. THOMPSON WATER TUBE BOILERS, Ltd., J. Feb. 2, 1955 [Aug. 9, 1954], No. 23120/54. Class 51 (1). [Also in Group XIII] In a steam power installation in which steam is supplied from a boiler (see Group XIII) to the turbine of a turbo-alternator, oil burners are provided for heating the superheater when starting up the boiler after a temporary shut-down to boost the steam temperature and thus avoid a flow of cooler steam into the turbine which may still be near normal operating temperature. As shown in Fig. 1, each burner consists of oil nozzle 1 contained in a tubular combustion chamber 2 at the apex of a perforated conical element 3, the wall of the chamber 2 being provided with holes 4, 5 respectively located behind and in front of the element 3. The combustion chamber 2 is surrounded by an annular casing 6 having an inlet 7 for combustion air. The casing 6 has an internal baffle 8 around which air entering at 7 must flow before passing into the chamber 2 through holes 4, 5. The combustion chamber is formed with a forward extension 9 which is perforated at 11 and outwardly flared at 10, the extension being surrounded by a casing 12 having an inlet 13 for gas or air under pressure. Circulation of the gas or air in the casing 12 is caused by a baffle 14 placed opposite the inlet 13. In operation, oil under pressure is atomized at the nozzle 1 and mixes with combustion air in the chamber 2 where it burns with a flame the outer extremity 16 of which has a temperature of about 3000 ‹ F. To avoid damage to the superheater tubes by overheating, the high-temperature combustion gas produced is tempered by admixture in the extension tube 9 with air or cool flue gas withdrawn from the boiler outlet flue and pumped through the inlet 13, the temperature of the gas mixture leaving the outlet 10 being about 1000‹ F.
