Title: Improvements in or relating to water tap
IPC: F16K21/04
Filed: 1934-12-24
Abstract: 449,261. Manually - operated valves. SMYTH, A. D. D., Sidi Gaber, York Road, Woking, Surrey. Dec. 24, 1934, No. 36907. [Class 135] A self-closing push tap comprises a horizontal tubular casing A having a seat B for a valve member C located on the inlet or high-pressure side and carried by a push spindle C<2> supported at both ends of the casing, and an outlet in the form of a grating or a series of openings A<6> remote from the valve and its seating so that the valve cannot be damaged by the insertion of a tool therein. The outer end of the spindle C<2> has a tapered or conical knob C<3>. The casing A is threaded internally to receive the seat B and a ported disc A<3>. The latter forms one end of the casing, and also serves as an abutment for a spring D which aids the water pressure in closing the valve. The valve C, which is of the mitre type, has flats on its sides. In a modification, the valve member has a plane closure surface engaging a similar surface in a multi-ported seat.

Title: Improvements in or relating to hydro-pneumatic pressure intensifiers
Inventor: ALEXANDER ROBERT LAWSON
IPC: F15B11/032
Filed: 1964-09-10
Abstract: 1,025,419. Hydraulic intensifiers. CHARLES S. MADAN & CO. Ltd. March 8, 1965 [Sept. 10, 1964], No. 37044/64. Heading F1P. In a hydraulic intensifier, a pneumatically operated piston 2 carries a plunger 15 extending into a cavity 20 in a work-ram 19 slidably mounted in a cylinder 8 filled with liquid. The end of the plunger carries a non-return valve 22 which is in the form of a piston slidable on the walls of the cavity and having a central aperture which is opened by hydraulic pressure on the downstroke of the plunger (into the ram cavity) and closed by a disc 24, carried on the end of the plunger on the upstroke. On the upstroke therefore, the ram, which has at the top a closure member 21 through which the plunger passes, is raised by the plunger acting through liquid trapped between the valve and the closure member. The valve 22 has axially extending grooves in its periphery to provide a leakage path for this trapped liquid. The ram cavity communicates with the cylinder chamber surrounding it by holes 28, 35 and an annular space between the ram and a sleeve surrounding it. Alternatively, the ram walls may be made thicker, the sleeve dispensed with, and holes may be drilled diagonally from the outer end of the ram cavity to a part of the outer wall of the ram which does not extend out of the cylinder. Alternatively, the cylinder and ram may have extensions so that radial holes from the outer end of the cavity always communicates with the cylinder chamber.

Abstract: 342,447. Oil gas generation. CHILOWSKY, C., 15, Rue du Lunain, Paris. Dec. 4, 1929, No. 37186. Convention date, Dec. 5, 1928. [Class 55 (ii).] In vaporizing oil to be subsequently gasified the oil is projected in atomized form together with air and steam or water over a wall exposed to the action of hot gases leaving the gas generator, the gas consuming apparatus, or other heat source. A vaporizing tube 1 may be formed of U-shaped members welded together at their outer edges which constitute the tube wall, the fins 5 thus formed extending into a space enclosed by a heat-insulated tube 2 through which hot gases circulate from an inlet 3 to an outlet 4. Oil fed through a pipe 9 may be atomized by air and steam entering through a pipe 8, or water may be introduced through a pipe 10, a groove 11 in the atomizer 7 producing a rotating jet. A member may be inserted in the tube 1 to confine the vaporized oil passage to an annular duct adjacent the tube wall which may have helicoidal fins for causing unvaporized oil to be flung against the wall. The Specification as open to inspection under Sect. 91 (3) (a) includes also the vaporizing and gasifying processes conducted in the absence of air and steam. This subject-matter does not appear in the Specification as accepted.

The knit articles are sequentially discharged from the machine 10, having a pattern drum 12, and are transferred by an air blast in timed sequence with the discharge through tubes 14, 16 into a heat assembly 18 for a prescribed period and are subsequently removed through a tube 20 to a container (not shown). The assembly 18 comprises a glasslined brass tube 22, Fig. 2, having small openings 24 and encompassed by an aluminium tube 26 having polytetrafluoroethylene end plates 27. An outer housing 28 is provided and an additional tubular member 32 may be provided. A heating unit 34 is mounted adjacent the tube 26 and is controlled by a thermostat 38, e.g. to a temperature of 190-250‹F. Water is directed onto the inner surface of the tube 26 by a jet 40 and steam or vapour passes through the openings 24. Excess steam escapes through a conduit 42 normally closed by a cap 44. Air blast jets 46, 48, 50, 52, or suction control the movement of the article. Doors 54, 56 close the housing 28 and each is movable about a pin 58, Fig. 3, by a cylinder 60 so that an opening 68 is aligned or misaligned with the tubes 16, 20, 22.  In operation, the flow of air through the jets 46, 48, 50, 52, the injection of water into the tube 22 and the opening and closing of the doors 54, 56 are controlled by cams on an extension 70, Figs. 1, 5 and 6 (the latter two not shown) of the pattern drum 12. Prior to the completion of knitting of an article the door 54 is opened and the door 56 closed (and, upon discharge of an article from the machine 10, the air jets are actuated to feed the article into the tube 22. The door 54 is closed and water is supplied through the jet 40, the amount of water being controlled by a timer (80), Fig. 6 (not shown). Prior to completion of the second article, the doors 54, 56 are opened and the first article is removed by the air blasts. Both doors 54, 56 are closed and the cycle is repeated.

Abstract: 1,143,319. Fluid-pressure servomotor systems. TELEDYNE INDUSTRIES Inc. Aug. 17, 1967 [Dec. 9, 1966], No.37866/67. Heading G3P. Apparatus for controlling the depth, d, Fig. 1, of a seismic streamer S towed behind a vessel V comprises a hollow cable C connected to the vessel at its leading end and to the streamer at its trailing end and having means H, Fig. 3, for admitting water at the latter end, means D for weighting the cable to have negative buoyancy when at least partially filled with water, a source 16, Fig. 2, of compressed gas, and valve means 26 connected between the leading end of the hollow cable and the source and adjustable to control the gas pressure and thereby the buoyancy of the cable to maintain its trailing end at a desired depth. The pressure in a depth measuring tube 18 is applied through a transducer 36 to a differential servo 30 which compares it with the pressure from a source 32 manually set to correspond to the desired depth of operation. If the depth decreases, the valve 26 is closed by the servo and pressure is slowly bled off from the cable through a valve 42 while an increase in depth opens the valve 26 to raise the pressure. A valve 28 may be left open slightly to flush the tube 18 continuously with air from the tank 16 or the tube may be blown free of water prior to each measurement. The streamer S, containing hydrophone transducers E, is filled with oil and is weighted by a copper cable while the cable C may consist of garden hose weighted by a further length of copper cable flexible enough to permit coiling on a drum. A regulator 20 provides a supply pressure of about 20 p. s. i. from the tank 16 which is filled with CO2. A gauge 34 indicates cable depth.
