Abstract: 936,824. Jib cranes on fishing boats. HYDROCONIC Ltd. Oct. 7, 1959 [Oct. 10, 1958 ; Nov. 7, 1958], Nos. 32488/58 and 35831/58. Class 78(4). [Also in Group XXXIII] A gantry 15 is pivoted at 16 at the stern of the fishing boat shown and is reciprocated fore and aft by rams 21 to lift the trawl on to the ship. Thus, the two trawl ropes pass over pulleys 22, 23 to winch drums, which haul in the ropes till the other boards thereof reach pulleys 22. The rams are then operated to swing the gantry inwards, i.e. to the right so that the other boards may be secured to stanchions 26 and are then operated to swing the gantry back outward to the left. The winch drums continued to haul in the trawl ropes till the trawl is close to the stern. A bag rope is then attached. The trawl is then elevated by means of the winch drums, and the elevated trawl (with gantry) is then swung inwards and over bulwark 28 by means of rams 21 to land the net with fish on to the working deck 29.

Title: Valve
IPC: F16K31/42
Filed: 1955-11-14
Abstract: 817,473. Fluid-actuated valves. INTERNATIONAL BASIC ECONOMY CORPORATION. Nov. 14, 1955 [Nov. 9, 1955], No. 32493/55. Class 135. A plunger valve has an internal bore 19 with end chambers 47, 47a having plunger stop means 23, 24, the bore containing a horizontallydisplaceable plunger 25 with its piston ends in the respective chambers, a pair of solenoidactuated fluid control valves connected respectively to each of the chambers for supplying when de-energized and exhausting when energized, pressurized fluid for moving the plunger, the control valves co-operating when both are de-energized to maintain the plunger with one end against its stop under the action of the fluid on the other end. The plunger slides through packing rings positioned by spacers to control the supply of pressure fluid at 39, Fig. 3, to one of two cylinder feed ports 41, 42 and exhaust from the other through a port 40. With the solenoid valve C energized to lift its plunger 53a and the solenoid valve B deenergized to keep its plunger 53 in its lower position, fluid pressure from 39 passes to an annular passage 65, through the open valve 60, the open solenoid valve 69 and passages 71, 72 to the left-hand chamber 47. The right-hand chamber 47a is open to exhaust via passage 72a, open solenoid valve 75a and passage 78a. The plunger valve is therefore moved to its right end position. Alternate energization and de-energization of the solenoid valves B and C will cause reciprocation of the plunger valve. If the electric supply fails or manual control is required for a full cycle operation, the plunger valve may be moved by alternately opening valve 60 and closing valve 60a, pressure fluid then exhausting via the loose stems 59, 59a of the override valves 60, 60a. The stops act as shock pads to reduce the impact of the plunger.

Title: Process for producing a clad reinforced composite
IPC: B22F7/04
Filed: 1971-07-14
Abstract: 1309519 Composite metallic sheet material PFIZER INC 14 July 1971 [17 March 1971] 33145/71 Heading E1K [Also in Division B3] A method of making a clad reinforced composite comprises distributing reinforcing material between matrix metal sheets 14 to form a core, enclosing the core between a pair of metal plates 18 to form an envelope, bonding the edges of the envelope, evacuating the envelope and applying heat and pressure to consolidate the reinforcing material, the matrix metal and at least one of the metal plates. Alternate layers of aluminium foil and boronon-tungsten filaments are enclosed in an envelope of stainless steel/aluminium alloy, which is closed and evacuated to a vacuum of a few millimeters of mercury. The composite is held under a pressure of 2000-4000 p.s.i. at 850‹-950‹F for 5-15 minutes and cooled slowly in a holding oven. Below 500‹F cooling is carried out more rapidly. Following this procedure, silicon carbide coated graphite ribbons are consolidated in an aluminium alloy matrix clad with a stainless steel/aluminium alloy envelope. In an alternative embodiment silicon carbide-on-tungsten filaments are embedded in a titanium alloy matrix in stainless steel/alumium cladding. This combination is heated to 1350‹-1450‹F at about 4,000- 6,000 p.s.i. for 10-15 minutes. The composite is then cooled slowly to below 750‹F. Other reinforcements comprise graphite, beryllium, boron, silicon carbide-on-boron, silicon carbide, aluminium silicate, boron nitride-on-boron boron nitride, silicon carbide-on-boron carbide, aluminium oxide, stainless steel, nickel alloyon-niobium, and tungsten. These reinforcements may be used with certain combinations of aluminium, copper, cobalt, magnesium, nickel, tantalum or titanium matrices with aluminium, copper, aluminium/chromium, niobium/tantalum alloy, tantalum alloy, titanium or brazing alloy cladding. When only one side of the reinforced composite is clad, one side of the envelope is made from mild steel plate suitably coated to prevent bonding to the matrix. The plate is subsequently stripped from the composite after cutting away the bonded edges of the envelope. The strippable plate may be pre-shaped to act as a former and the composite may be shaped by pressing, rolling, gas-pressure bonding and the like. The composite may be attached to other structures by welding, rivetting, friction or adhesive bonding, either by adhesives or brazing. It may also be protected by the application of a glassy coating or by electroplating, sputtering, anodic treatment or the like. The clad composite has a low mass and is suitable for use in moving machine parts. It may also be used in the construction of rocket nozzles, turbines, integral fuel tanks in aircraft wings, rocket fuel tanks, missile skins and in chemical plant where adaptability to high temperatures and/or large pressures in combination with either chemical inertness or catalysis is desired.
