Patent GB-1433952-A (GB)
Title: Control apparatus in an assembling machine
IPC: F15B11/20
Filed: 1973-07-03
Abstract: 1433952 Machines for setting buttons TEXTRON INC 3 July 1973 [11 July 1972 3 May 1973] 31742/73 Heading A3H [Also in Divisions B3 B4 and G3] A fluid control apparatus in a machine having a ram 10 and anvil 12 for assembling two component fasteners e.g. buttons, rivets, snap fasteners in a piece of material e.g. a garment, comprises a fluid motor 93 for moving the ram 10, a fluid motor 103 for moving the anvil 12, a valve 55 for controlling the motors 93, 103 and a pressure responsive device 130 for causing separation of the ram 10 and anvil 12 when the pressure in the anvil motor 103 reaches a predetermined value. When a plunger 61 in a valve 48 is depressed, air from a source 32 passes through the valve 48 to a valve 52 from which it passes by a conduit 56 through a valve 57, a conduit 58 and into a valve 60. A rod 88 in the valve 60 is moved to the left to allow a main conduit 68, connected to the source 32 through a reservoir 44, to be connected to an inlet conduit 76 of a cylinder 75 whose piston 74 is thereby moved to the right causing fastener elements to be moved adjacent the ram 10 and anvil 12. An end chamber of a valve 72 is exhausted to atmosphere through a passage 84 and port 86 allowing a rod 90 to be moved to the right by a spring 92 to cause the main conduit 68 to be connected to a passage 87 so that the rod 88 is returned to its initial position. Subsequently the valve 72 and fastener feed motor 73 are returned to their initial positions, due to connection between the main conduit 68 and a passage 84 and a conduit 78. When air is supplied through the inlet conduit 76 of the cylinder 75, pressure is applied through a conduit 79 to lower a rod 78 in the valve 57 against a spring 180 to disconnect the conduits 56, 58 until the motor 73 has returned to its initial position. When the plunger 61 is depressed, air pressure is also supplied into the control valve 55 via a conduit 53 to lift a rod 118 causing the main conduit 68 to be connected via a port 69 to inlet conduits 100, 112 of the motors 93, 103 which are operated to move the ram 10 and anvil 12 towards each other. The piston 104 in the anvil motor 103 is moved down at a slower rate due to an adjustable constriction 114 in the inlet conduit 112. When the lever 26 connected to the anvil 12 is pivoted by the piston rod 108, a plunger 64 in a valve 52 is lowered to connect the conduit 53 to atmosphere. When the pressure in the anvil motor 103 reaches a predetermined value due to the contact pressure of the ram and anvil 10, 12, a diaphragm 158 and an attached valve member 160 of the device 130 are raised against the bias of a spring 168 to cause the rod 118 to be forced down and the motors 93, 103 to be returned to their initial positions. The predetermined pressure may be set by an adjusting screw 164 which adjusts the force of the spring 168.

Title: Improvements in or relating to methods of bonding metallic bodies to non-metallic bodies and articles produced thereby
Inventor: HEAP HARRY RODNEY
IPC: B23K35/00
Filed: 1962-08-22
Abstract: In a method of bonding a metallic body to a non-metallic body in which the bodies are heated at a predetermined temperature for a predetermined time with at least one metallic layer between the bodies, to form a single article, the article is stress relieved, the layer is of at least one metal chosen from titanium, zirconium and hafnium, the time is longer than the minimum time required to bond the bodies or the heating is carried out in argon.  In an example a mild steel body is bonded to devitrified glass ceramic by placing a titanium foil next the ceramic and a foil of silver-copper eutectic next the metal, clamping the assembly in a jig of lower expansion coefficient than the assembly to exert pressure on the assembly during heating, and heating the assembly at 825 DEG  C. for 30 minutes longer than the minimum time required to bond the bodies. The cooled article is stress relieved by heating to 650 DEG  C. for 30 minutes and then cooling.  The bonding may be carried out in argon, helium, hydrogen, argon/hydrogen mixture or in a vacuum. Argon/nitrogen is also mentioned.  It is stated that butt or conical joints may be formed.

Title: Method of Diffusion Bonding Sheets together
IPC: B23K20/18
Filed: 1966-07-18
Abstract: 1,157,893. Making honeycomb core and bellows; welding by pressure. HEXCEL CORP. 18 July, 1966 [23 July, 1965], No. 32256/66. Headings B3A and B3R. In diffusion bonding together sheets at predetermined positions over their faces, a stack of sheets is formed with adjacent sheets separated by one or more members of a pressure transmitting material which is different from the material of the adjacent sheets and with the members offset so that no two members are directly above each other and separated by only one sheet and the stack is subjected to pressure normal to the sheets and heat to directly bond together adjacent sheets only at places above and below the members. A number of metal foils 12, Fig. 1, are arranged in a stack 11 with strips 13 between the foils in staggered relationship. The stack is arranged in an enclosure 61, Fig. 4, which may be evacuated or contain inert gas, between a press bed 62 and a movable press platen 63 which have raised portions 62<SP>1</SP>, 63<SP>1</SP> for applying pressure to the stack in the regions of the strips. Flat surfaces may alternatively be used. The platen 63 is forced downwardly by hydraulic rams 64 and while under pressure the stack is heated to diffusion welding temperature by passing current through the stack from one end to the other by clamps 67 attached to a current source. This method of heating is employed when the foils have high resistance, e.g. of stainless steel, but when the foils are of copper resistance element strip heaters are applied to the top and bottom of the stack. The regions of the foils above and below the strips are thus diffusion welded together and the welded stack is expanded to form an open cell honeycomb structure. The strips are then removed by high-pressure water or air or by etching. In one example aluminium sheets are spaced by zirconium strips and are heated in vacuo by strip heaters at the top and bottom of the stack, a pressure of 7500 p.s.i. and a temperature of 800‹ F. for 20 minutes being used and the stack being pulled apart by pins inserted into the stack edges. In another example sheets of 50% iron-50% nickel are spaced by strips of an inorganic powder in an inorganic solution and are heated in vacuo by passing current through the sheets. A pressure of 2400 p.s.i., and a temperature of 1050-1100‹ F. for 10 minutes are employed and then reduced. The strips are removed by acid. Strips may be left in the honeycomb. A number of annular sheets are similarly bonded using rings of stop weld material to provide on expansion a bellows. Sheets of titanium alloys may be welded.
