Abstract: 688,854. Cigarettes and cigarette-making machines. GAMBLE, H. July 24, 1951 [July 31, 1950], No. 19029/50. Class 130. Double mouthpiece cigarettes each containing both a formed plug 8 at the mouth end and a cotton wool or other soft wad 1a adjacent the plug have the wads cut from a length of material 1, Fig. 1, as by scissors 2, pressed into a shaping device 6 and thereafter inserted into the paper tubes 7 of the respective cigarettes. In Fig. 1 tubes 7 having previously inserted plugs 8 are brought in turn on a flat or revolving disc conveyer 9 into line with a reciprocating shaping device 6 having a spoon portion 4 which enters an aligned tube 7 after a reciprocating hollow pusher 3 has forced a wad 1a into the device 6, the wad being then blown along the tube into firm contact with the corresponding plug 8 by compressed air passed through the pusher 3. In Fig. 9 wads 16 cut by scissors 12 from a length of material 1 forwarded by a roller 11 are pressed by a pusher 13 into a circumferentially spaced series of shaping holes 14 in an intermittently rotated disc 15, and when the holes during rotation coincide with similarly spaced holes in a further intermittently rotated disc 17 and containing plugs 20 inserted by a pusher 19, the plugs and wads are ejected together by a pusher 21 into a reciprocating spoon 22 from which they are transferred in known manner, with the aid of a stripper claw or wire (not shown) passing through a slot in the spoon 22, into cigarette tubes 23 successively located on the spoon. An oscillatory pricker 27 may pierce each wad in turn and drive it partly into the mating plug. Alternatively, the wad may be caused to adhere to the plug by wetting the adjacent plug face, during transit on the disc 17, with glue applied by a rotating star wheel co-acting with a transfer wheel running in a reservoir.

Abstract: 967,154. Vacuum melting furnaces. BALZERS PATENT-UND LIZENZ-ANSTALT. May 15, 1963, No. 19260/63. Heading F4B. [Also in Division B3] A vacuum melting furnace and casting machine comprises a main chamber 1 separated from an air-lock chamber 8 by a wall 7 and door 10, chamber 8 being openable to the atmosphere by a lid 8a and a platform 22 rotatable by a hollow shaft 26 to transfer one or more moulds 23 between the two chambers into line with the tilting crucible having an induction heating coil 4. Door 10 is removed from its seating by lever 12 and rotated by lever 13 through linkage 11. Preheated moulds placed on the platform are kept hot by a heating coil 24 having leads 25 passing through the shaft 26. The latter is rotated by hand wheel 27 and moved vertically by lever 28. During casting, the mould may be rotated by a plate 47 on motor-driven shaft 46 which is raised and lowered by a lever 48. The platform 22 may be rotated by a motor through bevel gearing and a drive shaft inside the shaft 26, Fig. 2 (not shown). Instead of the device for rotating the mould during casting, a shaft 51, Fig. 3, extends through the furnace wall 50 supporting a plate 52 having a connection 55 to a vacuum pump 57 and carrying a precision mould 54 on a spacer ring 53, the mould having a porous bottom. In this case, the furnace chamber 1 may be filled with a neutral gas, e.g. argon, so that the combined pressure of the gas and the suction of pump 57 ensures a clean casting.

Title: Improvements in or relating to the refining of steels
IPC: C21C1/00
Filed: 1932-07-07
Abstract: In a process for refining iron, pig iron, or steel, such as basic steel, molten iron is poured simultaneously with a suitable slag superheated to a temperature above its melting point into a ladle without the application of heat, whereby the metal and the p  slag is mixed intimately before settling in the ladle.  The slag contains in addition to lime, silica or calcium fluoride and may also contain calcium carbide or reducing substances such as carbon in blocks or in suspension, and metals or alloys such as silicon, ferro-silicon, aluminium, aluminium-silicon, calcium silicide, manganese ferro-manganese or pig iron which may be employed for deoxidizing purposes or may constitute a permanent addition to the steel.  These additions may be melted and poured into the ladle before the slag, and the metal, are poured in.  Before melting the slag in an electric furnace, a small amount of iron &c. which may be part of the metal under treatment which serves as a conductor at the bottom of the furnace may be converted into deoxidizing alloys by the addition of reducing agents such as silica, aluminium, manganese or titanium and metals or alloys which eliminate nitrogen contained in the metal under treatment or serve as permanent additions such as chromium or nickel may be added to the steel &c. in the furnace.

The lever 46 is bimetallic to compensate for the temperature of the fuel in the housing. The bell-crank 41 has an arm 43 engaged by the fulcrum 44 and an arm 42 fixed to a control valve 67 which is moved by centrifugal weights 64, on a shaft 60 rotated by the engine, to provide a force responsive to the square of the rotational speed of the engine. The valve 67 controls the supply and exhaust of fluid to the opposite side of a piston 80, the movement of which rotates a lever 85 and through links and linkage 90, 91, 92 causes rotation of a cam 93 to adjust the force of a spring 100, through lever 96, which acts on the bell-crank 41 through lever 103.

Title: Improving wheat and flour
IPC: A21D6/00
Filed: 1963-05-16
Abstract: In improving a cereal product, namely wheat or flour, the product having a moisture content between 14 and 21%, by weight, is heated, as by live steam, to a temperature within the range 99 DEG  to 101 DEG C., preferably 100 DEG  C., for a period within the range 3 to 5 minutes, preferably 4 minutes.  Loss of moisture is prevented during the heating.  Treatment according to the invention inactivates liquefying enzymes, such as alpha amylase, and coagulates or denatures gluten, but does not gelatinize starch sufficiently to make the treated product sticky.  Treated wheat, e.g. after being dried, may be milled to yield flour.
