Abstract: 1304083 Ignition systems HITACHI Ltd 14 Aug 1970 [22 Aug 1969] 39374/70 Heading F1B A battery powered ignition circuit for a multicylinder internal-combustion engine comprises an ignition coil 14 and breaker contacts 16 for interrupting the series connection of the coil primary winding 142 to the battery 10 and an additional inductance 32 connected in series with the primary winding in such manner that the mutual inductance between the additional inductance on the one hand and the primary winding 142 and the secondary winding 144 of the ignition coil on the other hand is substantially zero. The induced voltage of the additional inductance at the instant of ignition of each of the spark plugs 24, 26, 28, 30 is superposed on the induced voltage of the primary winding. The value of the additional inductance is such as to restrike the arc between the contacts of the breaker.

Abstract: <PICT:0903872/III/1> <PICT:0903872/III/2> Carbon black is produced by injecting an axial stream of liquid make hydrocarbon in vaporized or atomized form and a rapid turbulent surrounding longitudinal stream of fuel gas and air from a cylindrical inlet chamber to an enlarged cylindrical combustion chamber.  As shown in Fig. 2, oil is injected through a flame holder ring 10 from a pipe 44 and spray nozzle 22 in an inlet chamber 7 into a combustion chamber 6 where it is decomposed by the simultaneous combustion therein of a mixture of fuel gas and air formed by countercurrent injection of fuel gas from a series of nozzles 15 in a ring 14 into a stream of air passing through chamber 7 to chamber 6.  As shown in Fig. 3, the fuel gas passes through a pipe 40 surrounding pipe 44 and is injected outwardly from a series of nozzles 42 behind a flame holder disc 41 carried by pipe 40.

IPC: C22C1/02
Filed: 1959-12-08
Abstract: A metal boride such as aluminium boride can be produced in the one-step process of preparing a refractory metal alloy (see Group II) by reacting an oxide of at least one refractory metal which includes the element boron with a reducing metal such as aluminium or magnesium, the reaction being performed in the presence of a non-reacting metal such as copper or by using excess reducing metal; and in the presence of a molten salt capable of dissolving the slag-forming oxide of the reducing metal, the temperature being above the melting-point of the metal or metals.  For example, in preparing aluminium boride contained in an alloy of boron and aluminium, an intimate mixture of boron oxide B2O3, and cryolite is added to excess molten aluminium at 970 DEG C. contained in a crucible under an argon atmosphere whereby, after the reaction in which the Al2O3 slag formed dissolves in the molten cryolite, the melt is heated to 1120 DEG C. and the metal phase separated.  The ratio of Al2O3 to cryolite may be between 1:2,2 and 1:8,0.ALSO:A refractory metal alloy is prepared in a one-step process by reacting an oxide of at least one refractory metal of the group titanium, molybdenium, chromium, zirconiumin maniganese, vanadium, thorium, beryllium idium, tungsten, uranium, and including the element boron (see Group III), with a reducing metal such as aluminium or magnesium, the reaction being performed in the presence of a non-reacting metal such as copper or by using excess of the equivalent amount of reducing metal, both being capable of alloying with the refractory metal, and at a temperature above the melting-point of the metal or metals, e.g. between 900 DEG  and 1600 DEG  C., whereby the refractory metal oxide is reduced to the metal and a slag-forming oxide of the reducing metal is formed, and in the presence of a molten salt capable of dissolving the slag.  Other oxides may be included such as Fe2O3 for alloying.  The molten salt preferably consists of a Group I to III metal chloride and/or fluoride having a boiling-point above 700 DEG  C., e.g. cryolite with or without ZnCl2, NaCl and CaF2, AlCl3, CaCl2, or KCl.  The ratio of oxide slag formed to the salt may be between 1 : 2.2 and 1 : 8.0. The molten salt and oxide slag may be separated from the alloy formed and electrolysed to recover the reducing metal, e.g. Al, and salt, e.g. cryolite, for recycling.

Abstract: A shoe upper is mulled by subjecting the upper to an atmosphere of saturated water vapour at from 55 DEG C. to 75 DEG C. and, at least one minute before removing the upper from the atmosphere, spraying the upper with cold water.  Preferably the upper is subjected to an atmosphere of between 60 and 65 DEG C. for about five minutes and is given two fifteen-second atomized sprays which deliver about 9 gms of water on to each upper, the first shortly after entering the atmosphere and the second after about two minutes.  A suitable apparatus consists of a cylindrical chamber which has a 30 degrees open sector and a closed sector which is closed by curtains.  The uppers are carried by four horizontal, vertically spaced circular supports which are rotated once every five minutes in increments of 30 degrees.  Atomizers are provided above each support, one just inside the entry region of the chamber and one diametrically opposite the open sector.  The uppers are supported on grids and each upper may be subjected to a blast of cold air just before it leaves the sector to remove any excess moisture on the surface of the upper.
