IPC: B21K1/22
Filed: 1945-05-01
Abstract: 607,205. Making cased valves. EATON MANUFACTURING CO. May 1, 1945, No. 10988. Convention date, March 31, 1944. [Classes 83 (ii) and 83 (iv)] Jointing by forging.-A method of bonding dissimilar metallic members comprises providing a corrosion resisting member with a tapered cavity in one end inserting into the cavity in a non-oxidising atmosphere, the tapered end of the other member of high tensile strength and applying axial pressure to the assembly, which may then be heated and forged to the desired shape. The invention is described as applied to the manufacture of a hollow poppet valve. A member 10 comprising a cylindrical stem 12 and an upper tapered portion 14 is formed from a metal having high tensile strength at elevated temperatures. A cap member 22 having an interior opening slightly smaller than the tapering portion 14 is formed from a corrosion resistant alloy such as 80 per cent nickel and 20 per cent chromium. The two members are assembled under pressure as shown in Fig. 3, in a non-oxidising atmosphere, and the assembly is heated and forged to the form shown in Fig. 5 and finally forged and machined to the final form shown in Fig. 7. Should any defects occur at the line of join of the two materials, an annular portion including the defective part is cut away and a ring 42 of one of the materials is welded or otherwise inserted within the cut.

Title: A combined starting vaporizer and fuel economizer for internal combustion engines
IPC: F02N99/00
Filed: 1927-04-26
Abstract: 288,038. Stanaway, W. E. April 26, 1927. Vaporizers, external. - A combined starting vaporizer and extra-air admission device comprises a vaporizing chamber 10 with end caps 11, 12 of which 11 supports a rod 13 through insulation 14 and 12 is bored to receive two pipes 32, 27. The pipe 32 has a three-way valve 22 which can put a fuel container 30 in communication with a fuel supply 29 or with the vaporizing chamber 10. The pipe 27 has a valve 23, which can place a branch 26, which leads to the induction pipe, either in communication with the vaporizing chamber, to supply starting mixture, or through a pipe 28 with the atmosphere to supply air alone. The rod 13 supports a perforated disc 17, Fig. 1, to which are attached heating elements 18 earthed at 19 in the cap 11. Contact of the elements with the rod 13 or casing 10 is prevented by absorbent asbestos 20. Current from a battery is led to the elements through a wire 16 which is connected to a switch element 37, Figs. 5 and 6. The valve 22 is actuated through a link 24a and universal couplings, by a rod 24 having an actuating arm 25 and, keyed to it, a disc 35. The valve 23 is actuated by a push-bar 38, which, in one position of the disc, Fig. 5, can slide through a slot 42 therein. When the bar 38 is pushed in, the disc enters a notch 41 in the bar and is then capable of being rotated to the position shown in Fig. 6, when the switch element 36 carried by the disc engages the element 37 and completes the circuit through the heating elements 18. The bar 38 being in its inner position and the arm 25 in the position shown in Figs. 4 and 5, the valves are in the position shown in Fig. 1, and fuel from the container 30 enters the vaporizing chamber 10. If now the arm 25 be moved to the position shown in Fig. 6, the electric circuit is closed, the element 18 heated and the fuel is vaporized and admitted through pipe 26 to the engine manifold. At the same time, the container is cut off from the vaporizing chamber and placed in communication with the supply pipe 29. By rotating arm 25 and the disc 35 to the position shown in Fig. 5, the electric circuit is broken, and the bar 38 may be pulled out to move valve 23 so as to close the pipe 27 and connect the pipe 26 with the air inlet 28. The vaporizing chamber may be arranged horizontally.

Title: Process of and apparatus for making high temperature-resistant materials
IPC: C04B33/32
Filed: 1957-04-05
Abstract: 822,083. Moulding refractory materials. KNAPF, S. G. April 5, 1957 [April 30, 1956], No. 11150/57. Classes 22 and 87(2). Refractory materials are made by compressing in a mould chamber a uniform finely-divided particle mixture composed of (i) a high melting temperature and relatively inert component, (ii) a reducing metal component, and (iii) a metallic compound component chemically-and: exothermically reducible by reaction with compone n t (ii) to form a high melting compound, namely a metal oxide, carbide or nitride ; passing electric current through the mixture while being compressed to heat it to a temperature at which the exothermic reduction will occur ; then further heating the mixture by current passage to at least maintain the temperature resulting from the exothermic heating ; and finally cooling the resulting integrated product. More specifically, component (i) is of the class consisting of metal oxides, carbides, and nitrides and carbon with a melting temperature in excess of 2000‹C. ; component (ii) is of the class consisting of zirconium, magnesium, and aluminium; and component (iii) is of the class consisting of the anhydrides of chromium, tungsten, molybdenum, and boron ; the carbonyles of chromium, tungsten and molybdenum ; and the cyanides of calcium, nickel and iron. The initial mixture, which contains by weight 20 to 70%, 10 to 40%, and 20 to 40% respectively of the three components and in which the particles are predominately within the 20 to 400 micron size, is heated under a pressure of 2 to 15 tons /sq. in. in a mould chamber 10 having a bottom removable plug 15, walls 11, 13 lined with ceramic 16, and an upper piston 17 to which the compressive force is applied. Cooling elements 22, 24 engage walls 11, 13 and plug 15 and piston 17 have cooling fluid circulated through passages 28. The temperature of the mixture is brought quickly up to 1200‹C. at which exothermic reaction of components (ii) and (iii) occurs, heating being continued and the temperature rising to 1200‹ to 1800‹C. Component (iii) is converted to one or more fluid constituents, gaseous or liquid, e.g. chromium, anhydride, carbon monoxide or nitrogen, which diffuse uniformly throughout the entire mass. Because of the high current passing through the mass and its high temperature, the diffused constituents are highly reactive and convert the metal component to one or more high melting temperature compounds, i.e. oxide, carbide, or nitride as a high temperature resistant binder in the final product. Such conversion is made to occur more completely by continuing the temperature rise to a level that may range as high as 2300‹C. by suitable adjustment of the current flow.

Abstract: 892,049. Reciprocating pumps. LUCAS (INDUSTRIES) Ltd., JOSEPH. July 4, 1958 [April 10, 1957], No. 11683/57. Class 102(1) [Also in Group XXIX] A hydraulic pump c for use in a hydraulic power transmission means for road vehicles has its swash-plate e or other displacement varying means adjusted by a servomotor g supplied with motive fluid from the pump, and an auxiliary pump p is provided for supplying motive fluid to the servomotor when the main pump c is at or near zero displacement. The servomotor g takes up a position corresponding to the position of a control valve i adjusted by a driver's lever o. When the lever is moved to a position corresponding to zero or near zero displacement of the pump a striker x on the lever engages a plunger w which depresses a plunger u to move a valve s to a position in which it interconnects the main conduits a, b of the pump c. The auxiliary pump b then discharges through spring loaded valves q into the conduits a, b so that pressure is available for operating the servomotor. This pressure passes to the servomotor through spring loaded valves m. When the main pump c is again operative one of the valves q, depending upon which of the conduits a, b is at higher pressure, closes whilst the other allows the auxiliary pump to maintain a minimum pressure in the system. Surplus flow from the pump p discharges through a spring loaded valve r. The valve s also serves as a safety valve to limit the pressure in either of the conduits a, b by moving against either of a pair of loading springs t to interconnect these conduits in the event of excessive pressure in either of them being applied to cylinders y.

Abstract: 695,237. Lathe details. ARON, E., and PULMAN, W. E. R. May 9, 1952 [May 18, 1951], No. 11721/51. Class 83 (iii). Work-feeding mechanism for an automatic lathe &c. comprises an operating member to apply feed to the work through an adjustable transmission which can yield against the action of a spring and is so arranged that the extent of movement applied to the work for a given movement of the operating member may be varied and which adjustment is arranged to vary the loading on said spring whereby yielding takes place at substantially the same load on work irrespective of the variation in mechanical advan. tage of the operating member over said work consequent upon the adjustment. The feed tube 12, Fig. 2, arranged within the hollow spindle 10 is secured to a reciprocable cylinder 17 by a latch 16. A collar on the cylinder is engaged by a pad 21, Fig. 3, connected by a pin 20 to the end of one arm 19 of an H-shaped lever 18. The lower end of this arm carries a follower 22 engaging a cam 23 on a "one revolution " cam-shaft 42, Fig. 4, which also controls the chuck opening and movements of a stock-stop. Vertical movement of the H- lever is prevented by a block 44 moving in a slotted guideway 24 fixed to the machine frame, a pin 26, Fig. 3, securing the block between the lower arms of the lever. The shorter vertical arm 25 of the latter is slotted on its side face and carries a block 28, a hole in which is engaged by a pin 34. This pin is carried by a second block 33 slidable along a slot in a lever 29 pivoted to the machine frame at 30. The block 33 is adjustable along the lever by a screw-and-nut device to vary the stroke of the work-feeding tube. A tension spring 34, Fig. 4, is secured between a fixed part of the machine and the adjacent end of the pin 34. A boss 40 on the upper end of the lever arm is normally held by the tension spring in engagement with an adjustable stop-screw 41. When the work meets an obstruction or engages the stock-stop during a forward feed, the H-lever pivots about the pin 21 and extends the spring 34, the lever 29 pivoting anticlockwise in the Figure. As the spring is moved nearer to the pivot of lever 29 its effectiveness is reduced correspondingly and the effectiveness of the leverage to operate the spring is reduced at the same time so that the thrust on the bar at overload remains constant.
