Title: Method and means of making valve bodies
IPC: F16K27/02
Filed: 1964-05-06
Abstract: 1,018,018. Producing valve bodies; tubeexpanders; stamping. GRINNELL CORPORATION. May 6, 1964 [May 6, 1963], No. 18917/64. Headings B3A, B3E, B3J and B3Q. In a method of forming a valve body from a metal cylinder, a piece of heated tubing 100 is held in die parts 110, 112, which may be heated, and plugs 120 are inserted in either end of the tubing (Figs. 10, 11, not shown). Between the plugs 120 lies a cylindrical member 128 positioned opposite a hole in the tubing wall. The member 128 is connected to a guide 136, which is connected to a press part capable of pulling the member 128 upwardly to form an enlarged hole having a lip 138 (Figs. 12 to 15, not shown). Simultaneously a die component 140 engages the tubing to form the weir 18 (Fig. 1). The guide 136, member 128 and guiding sleeve 126 therefor are withdrawn except for a loose split ring 146 at the bottom of the sleeve 126 (Fig. 16, not shown). A further tool 147 is inserted, the lower end part 148 of which fits over the formed weir. A sleeve 150 slides downwardly over the part 148 to form the flange 20 (Fig. 1). The tubing section is removed from the die parts 110, 112, the ends cut square and is placed in further die parts having an integral weir engaging part (Fig. 26, not shown). Plungers 120a are forced into the ends of the tubing to form the socket end connections 31, 32 and when the valve body is taken from the dies, the ring 146 is removed. In an alternative embodiment a valve body having no weir is formed from a tube 180 (Fig. 34, not shown) located in a pair of dies and filled with a fluid material, which material is compressed by a plunger 184 to form the tube (Fig. 35, not shown). The fluid material is removed and the tube trimmed (Fig. 36, not shown). Die components 198 are inserted at either end of the tube and in the side opening so that the entire inner surface thereof is supported and a flange formed from the walls 194 (Fig. 37, not shown). The underside of the flange is in contact with the outer wall of the tube and so no split ring is required.

Title: Improvements in or relating to apparatus for inspecting solid parts by supersonic shear waves
IPC: G01N29/04
Filed: 1946-06-26
Abstract: 615,578. Testing materials by supersonic vibrations. SPERRY PRODUCTS Inc. June 26, 1946, No. 19100. Convention date, June 28, 1945. [Class 118 (ii)] In supersonic apparatus for inspecting solid parts an intermediate solid member has a face in engagement with the solid part and a face for receiving generated longitudinal waves, this member also having a reflecting surface at such an angle with respect to the longitudinal waves transmitted from the generator that shear waves will be directed through the face that is in engagement with the solid part. As shown, a specimen 16 to be tested is placed in an oil or other liquid bath 12 in which are disposed a transmitter 10 and a receiver 40 of longitudinal waves. The face 18 of the specimen is inclined at an angle such that when struck by a longitudinal wave 17 the resultant reflected shear wave 21 has most energy and travels horizontally through the specimen to strike the face 25. The face 25 is inclined at such an angle that the reflected longitudinal wave 31 passes vertically downwards to the receiver 40. Any flaw 26 lying in the path of the shear wave 21 will cause a reduction in the reading of the indicator 42 in the amplifier 41. The crystal 10 may act as transmitter and receiver, the flaw 26 reflecting shear waves which are reconverted into longitudinal waves at the face 18. Test specimens not having inclined faces may be interposed between two members having inclined outer faces, such as by cutting a body shaped like the specimen 16 along the line 50 to form two members A, B. The oil bath may be dispensed with, and the crystals 10, 40 attached to the specimen by cement or through an oil film. In a further modification, used for intensive inspection of a small localized region of a specimen, the face 18 is curved so that a series of reflected shear wave beams converge to a focal point within the specimen. A flaw at this point will reflect the beams which upon further reflection at the face 18 will return longitudinal waves to the crystal 10. The opposite face 25 may be similarly curved and a second (receiver) crystal used as shown in Fig. 1.

Abstract: 247,307. Brandwood, J. Aug. 16, 1924. Alkali cellulose.-Apparatus for the treatment of wood pulp with alkaline liquids without handling and constituting a step in the manufacture of artificial silk, comprises a tank through which the pulp is carried by means of a conveyer and a press over which the conveyer passes and the press-plate of which is adapted to descend on to the layer of pulp at intervals at which times the motion of the conveyer is automatically stopped. A suitable apparatus comprises a tank 8, Figs. 1 and 3, through which passes a pair of conveyer bands 10, 11 between which the pulp is carried through the tank; the band 10 is supported by rollers 12 - - 16 and the band 11 by rollers 17 - - 19, 21 - - 24; certain of the rollers are adjustably mounted, for example, in the manner shown in connection with the roller 17, for the purpose of varying the tension on the bands, while others of the rollers can be differentially adjusted with respect to the edges of the bands for the purpose of ensuring their even travel. Rollers 46, 40 press against the rollers 14, 21 of the bands 10, 11 respectively, and the roller 40 is connected by spur gearing to the driving mechanism, and from this roller the drive is taken to roller 21, and from this by chain gearing 44 to the roller 46 associated with the band-carrying roller 14. The driver band 11 is arranged to project at the entering end of the tank so as to form a platform on which are placed the sheets of pulp, and at the other end it is carried across the table 20 by the press; beyond the latter, the band travels downwardly over the roller 21 for the purpose of discharging the treated material, a brush 77, or a doctor blade being provided for removing particles of pulp from the band. The roller 40 is driven from a shaft 64, Fig. 5, itself driven by suitable reduction gearing; for the purpose of securing the necessary intervals in the motion of the conveyer bands, the gear 66, Fig. 5, connecting the shaft 64 and roller 40 is without teeth on a portion of its periphery; at such times as the roller 40 is stationary, a cam 65, Figs. 5 and 6, carried by the shaft 64 is arranged to open the valve 70 of the hydraulic press 72 carrying the press-plate 26; alternatively, the cam may be arranged to operate directly the plate 26 of the press. The gearing may be arranged so that each portion of the pulp is subjected to several pressings in the press 20. Heating-pipes 74 are fitted in the tank 8. According to the Provisional Specification the intermittent driving of the conveyer bands may be obtained by means of clutch-mechanism.

Title: Hydraulic turbo couplings
IPC: F16D33/16
Filed: 1960-06-01
Abstract: 896.195. Hydraulic couplings. VOITH G.m.b.H., J. M. June 1, 1960 (June 2, 1959], No. 19458/60. Class 69 (2). An hydraulic coupling comprises an impeller 4 and runner 5 in a working circuit in unrestricted communication with a liquid chamber 8 rotatable with, and of substantially the same diameter as, the working circuit, a scoop tube or overflow device 9 adjustable within the range of the diameter of the working circuit, and a filling device 21 which is arranged to discharge liquid through a delivery pipe 20 into the working circuit, the scoop tube or overflow device 9 and the pipe 20 communicating with a common filling duct 18 which discharges into the working circuit. The impeller 4 is connected by gearing 2, 3 to a driving shaft 1 of an engine and the runner 5 is connected to an output shaft 6. The chamber 8 is formed by a casing 7 connected to the impeller and the scoop tube is secured to a shaft 12 and connected by a space 13 to a duct 14 which leads to a cooler 15 joined by a duct 16 to a valve 17, 23 in turn connected by the duct 18 to a filling space 19 and by the pipe 20 to the device 21 which may be of a two-stage centrifugal type pump. The movable part 23 of the valve is operated by a linkage joined to the shaft 12. In operation, the coupling is filled by liquid from the pump passing through the duct 18 and through the duct 16, cooler 15, duct 14 and scoop tube 9. When the orifice of the scoop tube is in its radially-innermost position, liquid withdrawn by the scoop tube passes through the duct 14, cooler 15, duct 16, valve 17, 23 and duct 18 to the filling space 19. Some of the liquid is by-passed to the sump 22 to utilize the cooling effect of the liquid therein, the pump 21 serving to replace the by-passed liquid and to replenish losses caused by leakage. The movable part 23 of the valve, may have a spring connection with the linkage so that when the scoop tube is moved rapidly outwards to empty the coupling, the pressure in the tube, and consequently in the duct 16, moves the valve to enable liquid to be returned to the sump through the pipe 20 against the delivery pressure of the pump. A manual or thermostatically-controlled valve may be included in the duct 18 to control the flow of liquid through the cooler. In other embodiments, the filling device may comprise an elevated tank or a gear-type pump which may be connected to the duct 14 between the scoop tube and cooler. A pressure-relief valve may be connected to the duct 14.

Class 110(3) The area of discharge of a jet propulsion nozzle is varied in part by movable members associated with the outlet of the discharge nozzle and in part by means of auxiliary jets issuing from the movable members. The exhaust nozzle 1, Fig. 2, of a gas turbine jet propulsion engine with reheating in the exhaust pipe, comprises two flaps 2 pivoted about axes 3 parallel and close to a diameter of the discharge nozzle. The flaps are operated by jacks 4 through connecting rods 5. The flaps 2 are provided with slots 7 to which a gas under pressure, for example compressed air from the compressor, is supplied through collectors 8. The gas is supplied through a control valve 11 and conduits 9, 10. For normal working the flaps are placed in the closed position shown and air supplied to the slots 7 to vary the effective area. When the afterburner is operated, the flaps 2 are also opened, thus giving the gases the maximum cross-section of discharge nozzle. The aerodynamic constriction jets may be put into operation in either of the two positions of the flaps 2 or may be applied alone when the flaps are open. In another modification, Fig. 3, having a pair of pivoted flaps 17, a discharge nozzle 13 is provided at the end of the nozzle 1 and further nozzles 22 provided close to the extremities of the flaps 17. The nozzles 13, 22 are separately connected to a source of compressed air through manifold 14, conduit 15 and control valve 16 and manifold 23, flexible connection 24, conduit 25 and control valve 26, respectively. During normal working without reheat, the flaps 17 are set in the closed position. The area of discharge may be varied by controlling the supply of air to the nozzles 22 by the valve 26. This valve may be controlled automatically in accordance with air-speed, altitude and temperature of ambient air. When the reheat is in operation, the flaps 17 arc fully opened and the area available is that of the orifice 12 which may be reduced by supplying air to the nozzle 13. The gases passing out of the nozzle 13 protect the flaps 17 from the action of the hot gases.

Abstract: 990, 811. Measuring tension in cables. JOHNSON & PHILLIPS Ltd. Aug. 31, 1961 [June 3, 1960], No. 19723/60. Heading G1W. For measuring the tension in a cable 12 being payed out or picked up by a cable-laying ship, the downward force on a sheave 16 is transmitted, via the axle 20 mounted on a lever 21 pivoted at 22, to a load-cell 23. This is connected to a Bourdon tube 24 the movement of which is transmitted via pneumatic bellows 25, diaphragm 27 and amplifying lever system 28, to a pointer 29 the scale markings for which are calibrated to give the cable tension. The pneumatic indicating system may be tapped off to pointers (including a pen-recorder) in various parts of the ship and may also provide a signal to control elements for varying the stroke of hydraulic motors on the main winding drum 15 or the hauling-off sheave 13 to vary the drive (in picking up cable) so as to maintain the tension constant. During pay-out of the cable the motors can act as pumps to give variable braking power. Specification 990,812 is referred to.
