Title: Improvements in or relating to flow control devices for regulating the flow of liquid through a tanker vehicle discharge hose
IPC: B64F1/28
Filed: 1959-10-19
Abstract: 938,222. Fluid-pressure servomotor control systems; valves. AD. STRUVER G.m.b.H. Oct. 19, 1959 [Oct. 18, 1958], No. 35410/59. Class 135. A device for controlling the flow of fluid supplied under pressure to a hose so as to maintain a predetermined pressure at the hose outlet comprises a throttle valve closure member 32, Fig. 1, secured to a piston 31 slidable in a cylinder 29 which forms an annular path for the fluid flow upstream of the throttle valve seat 38. The valve member 32 is loaded by a spring 36 and its position is governed by a control device 41 in accordance with the hose outlet pressure as measured at the throat 27 of a Venturi 25, which measurement allows for the pressure drop along the hose 26. The control device 41, Fig. 2, comprises a tubular double valve member 46, loaded by a spring 52, having a valve closure member 49 at one end controlling exhaust of fluid from the cylinder 29 and a hollow spindle 50 whose end forms a seat for a second valve member 47 which controls the supply of fluid to the cylinder 29. A diaphragm 76, loaded by an adjustable spring 88, is subjected to the regulated pressure at the Venturi throat fed to an inlet 78 and actuates the valves 46, 47 to control supply and exhaust of fluid pressure to the cylinder 29 to position the throttle valve member 32 to maintain the predetermined regulated pressure. A pressure relief valve is also provided to relieve excess pressure in the hose, for example when the hose outlet is closed. For this purpose, the opposite end of the valve member 47 co-operates with a seat 87 on the end of tubular member 48, secured to the diaphragm 76. If the pressure acting on the diaphragm rises sufficiently, movement of the valve member 47 is arrested by a stop 72 and the tubular member 48 moves to allow fluid in the pipe line to flow through inlet 69 and the tubular member 48 to a drain outlet 84. In a modification, the cylinder 29 is provided with the seat for a tubular throttle valve member which carries an annular piston subject on one side to the pressure in the pipe line and on its other side to pressure under the control of a device similar to 41 except that the lower valve on the tubular valve member controls fluid supply to the piston and the upper end of the tubular part controls the fluid exhaust. The pressure relief valve may comprise a diaphragm subjected on opposite sides to fluid in the pipe and at the Venturi throat.

In a method of making a blade ring assembly comprising a member 4 e.g. a rotor or stator for a steam turbine, and rings of blades 7, the blade roots 8 are fused to the walls of a peripheral groove 1 formed in the member 4 by using a high energy beam e.g. laser, or electron beam. Each blade root has two pairs 9, 10 of opposed surfaces, the surfaces 9 being at an angle to the blade equivalent to the required setting angle of the blade and with a dimension between them such that the blade root is a tight fit in the groove walls 2, and the dimension between the surfaces 10 being such that either the surfaces 10 of adjacent blades abut or are spaced at determined distance according to the required pitch of the blades. The energy of the beam is selected so as to penetrate substantially over the depth of the joint and any excess energy in the beam is absorbed by loose wires 6 extending below the joints, or by a portion (16) (Fig. 3, not shown), of the blade root. Each joint between the groove wall and blade roots may be fused in turn using a single beam, the work being rotated to form the peripheral weld. Slots 11 are provided in the blade roots 8 to give them resilience and to prevent cracking during fusing. Radially extending relieving holes 14 may also be provided. The welds of Fig. 1 may be ultrasonically inspected.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1931-12-31
Abstract: 381,793. Refrigerating. ELECTROLUX, Ltd., 153, Regent Street, London.- (Assignees of Platen-Munters Refrigerating System Aktiebolag ; 2, Norrmalmstorg, Stockholm.) Dec. 31, 1931, No. 36078. Convention date, Jan. 5. [Class 29.] Absorption systems.-A long column of liquid in a combined generator and rectifier vessel 1 is heated at its lower end, as by an element 25, and cooled at its upper end, as by a water jacket 20 or by air or an independent condensation-evaporation cooling system, whereby solvent vapour bubbles generated at the lower part are condensed in the middle part of the column, and refrigerant vapour bubbles are either condensed or absorbed at the cooled upper part, from which a conduit 7 leads the condensate or rich solution to the evaporator or to a re-absorber. The generator preferably contains small glass beads, shot, &c., as described in Specification 342,655, to prevent eddying of the liquid. In the system shown in Fig. 1, rich solution flows from the absorber 5 through a pipe 11 and a " pumping " pipe 2 to a chamber 13 at the top of the generator, and then downwards through a pipe 4 to a point in the column in the generator where the concentration is about the same as that of the inflowing solution. The chamber 13 is in gas connection with the top of the generator and also, by a vent pipe 14, with some part of an inert gas system between the absorber and an evaporator 8. The weak solution flows from the bottom of the generator through a pipe 6 to the top of the absorber. With low cooling-water temperatures almost pure condensate will flow through the pipe 7 to the evaporator, whereas with higher temperatures the liquid will be a more or less concentrated solution. Unevaporated refrigerant or solution in the evaporator is led by a pipe 9 to the pipe 11 and " pumping " pipe 2. In a similar system the evaporator and absorber are formed as pipe coils, and the pipe 11 passes downwards and the pipe 6 upwards through the liquid column in the generator to effect a better heat exchange. In a further system shown in Fig. 3 rich solution formed at the top of the liquid column in the generator 1 is led by the pipe 7 to a reabsorber 27 located below and receiving rich solution from the absorber 5, and the rich solution flows on to the evaporator. The gas mixture conduit 12 passes upwardly through the generator to be heated and is cooled by a jacket 29 in a descending limb.

Sheets are separated sequentially from the bottom of a stack 18 in a hopper by a rotating friction roller 14, arranged beneath a slot in the base-plate 10 of the hopper, and a rotating roller 20 which co-operates with two verticallyadjustable plates 26 to form a feed gap in the front of the hopper, the arrangement being such that the lowermost sheet is deflected downwardly to enter the feed gap. The roller 14 has a projecting insert 16 of rubber, the roller 20 has a precision ground facing 22 of hard rubber, and the lower ends of the plates 26 are tapered, and may be provided with rubber &c. inserts (27, Fig. 3). The base-plate 10 is pivoted at 40, and rests on a cam 42 which can be rotated to adjust the free end of the plate so that its upper surface is slightly above the periphery of the roller 20. The plates 26 are slidably mounted on the front wall 24 of the hopper, and are adjustable relatively to the wall, in a vertical direction, by screws 34 and compression springs 36. The plates 26 can also be urged upwardly away from the roller 20 and retained in that position by a lever (44, Fig. 2) and retainer plate (48), in the event of the feed gap being blocked by damaged sheets. Double feed of sheets through the feed gap is detected by a pair of rollers 52 on an arm 50 pivoted to a bracket on the wall 24, the arm having an adjustable abutment 54 at its upper end, facing a plunger 58 on a micro-switch 56. Thus, when two superposed sheets are separated, the rollers 52 are lifted, the arm 50 is rocked, and the switch 56 is operated to stop the drive of the rollers 14 and 20.

Title: Process for conditioning a substrate prior to electroless plating
IPC: C23C18/36
Filed: 1961-10-10
Abstract: A substrate of Pb, Sn, Cd and/or Bi, which is to be plated with another metal such as Ni or Co by applying an electroless plating bath comprising ions of the other metal and hypophosphite anions, is first conditioned by contacting the substrate with a solution containing Ni, Co or Fe ions and sufficient agent for selectively complexing ions of the metal(s) in the substrate, e.g. acetate and/or chloride ions, that on contact the substrate metal complexes with the agent so that the substrate surface exhibits a higher electrochemical potential than the Ni, Co or Fe ions.  The conditioning solution may also contain hypophosphite ions and is preferably maintained at between 90 and 95  DEG C. during contacing, e.g. for at least 10 minutes.  Prior to conditioning, the substrate is preferably cleaned by immersing successively in CH3OH, and KOH, HF, H2SO4 solutions, with intermediate rinsing in deionized water.  Examples of constituents in aqueous conditioning solutions are:  (a) nickel acetate at least 0.5 g./l., and acetic acid to reduce pH to 3; (b) NiCl2, NH4Cl, HCl, NaH2PO2, FeCl2, sodium acetate and acetic acid; (c) NiCl2, NH4Cl, ammonium acetate and acetic acid; (d) NiCl2, acetic acid, NaOH, and glycollic acid as a buffer; (e) CoCl2 at least 20 g./l., and acetic acid; (f) FeCl2, sodium acetate and acetic acid. Conventional electroless Ni plating solutions, e.g. containing NiCl2 or nickel ammonium sulphate and NH4Cl2, with glycollic acid, NaOH and NaH2PO2, may be converted into a conditioning solution by adding concentrated HCl with or without FeCl2.  After conditioning, the substrate may be plated with Ni from a conventional plating bath, e.g. containing NiCl2, acetic acid, sodium acetate, NaH2PO2, NH4Cl, or with Co from a bath containing CoCl2, NaH2PO2, NH4Cl, NH4OH, sodium citrate.  A second coating of gold may be plated from a bath containing KAu(CN)2, sodium succinate, NH4Cl, Na2H2PO2, nickel acetate, ammonium acetate and E.D.T.A.  The substrate may be the lead-tin solder plugs of an ultra-high frequency diode.  U.S.A. Specification 2,532,284 is referred to.
