Title: Improvements in the heating of furnaces
IPC: F23D14/00
Filed: 1947-08-27
Abstract: 646,805. Burners. BLANCHARD, P. Aug. 27, 1947, No. 23753. Convention date, March 10, 1942. [Class 75(i)] [Also in Group XII] A method of heating a furnace consists in projecting within the furnace a sheet of fuel substantially parallel to and close to one of the furnace walls and bringing primary air into contact with the sheet of fuel on the wall side and secondary air on the side remote from the wall, the primary air being caused to follow a helical path and the secondary air being given a radial velocity substantially greater than its axial velocity. As shown in Fig. 1 fuel is supplied from conduit 5 and emerges from the burner by holes 6, secondary air with or without the addition of oxygen being supplied under pressure through conduit 10 and issuing through holes 11. Primary air enters an annular chamber 8 provided with blades 9 which impart a helical motion to the stream which then flows along an annular passage 3 to the furnace. The Specification as open to inspection under Sect. 91 also describes a modified form of burner, Fig. 3 (Cancelled), provided with three concentric tubes 21, 22, 23. Secondary air is supplied through a conduit 24 to tube 21, the position of which is adjustable by means of handle 28, and emerges through longitudinal holes 47 and between members 41 and 45 at the end of the burner. Pulverulent fuel may be introduced at inlet 30 and gaseous fuel at inlet 32. Adjustment of handle 28 regulates the annular aperture, between members 57 and 41, through which the pulverulent fuel passes. Liquid fuel may be introduced into the gaseous fuel at 53. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to the electrolytic purification of titanium
Inventor: BOCKRIS JOHN O'MARA
IPC: C25C3/28
Filed: 1956-08-02
Abstract: 825,951. Electrolytic purification of titanium. MINISTER OF SUPPLY. Nov. 4, 1957 [Aug. 2, 1956], No. 23827/56. Drawings to Specification. Class 41. Titanium is purified by electrolytically decomposing under a rigorously purified inert atmosphere an anode of impure titanium in an electrolyte consisting of a mixture of fused halides of alkali and/or alkaline earth metals which is rigorously purified by removal of metals, hydrogen, oxygen and other titaniumhardening impurities. Typically the fused halides are purified in the same cell as is used for purifying the titanium, first by bubbling hydrogen chloride through the melts then electrolytically, the graphite anode and molybdenum cathode used in the electrolytic purification being replaced for the titanium purification by the impure titanium anode and a pure titanium cathode, which prior to insertion is etched in aqueous hydrofluoric acid and prior to the refining of the titanium is subjected to an anodizing treatment. The process may be performed in a silica crucible supported in a stainless steel shell surrounded by an electric heater. The upper portion of the shell and the removable cover are water-cooled and copper tubes brazed to and passing through the cover and fitted with releasable glands and rubber ring gaskets permit the insertion and removal of electrodes without contamination of the cell atmosphere and provide access for vacuum and inert gas, e.g. argon, lines.

Title: Anti-theft device for automobile vehicles
IPC: B60R25/02
Filed: 1975-06-03
Abstract: 1473614 Anti-theft device ANTIVOLS SIMPLEX SA 3 June 1975 [4 June 1974] 23912/75 Heading E2A An anti-theft device comprises a barrel lock 2, rotation of which effects the longitudinal movement and fastening of bolt 6. In the locked position shown in Fig. 1 bolt 6 is fully extended and, barrel 2 is prevented from rotating by a radial push member 4. Insertion of a key into the lock forces a key-sensor 3 outwards until the member 4 disengages the barrel.  Rotation of the barrel 2 by the key forces the stem 7 to the right by action of the cam 13 on tongue 11 and thus withdraws bolt 6. As shown in Fig. 5 the cam 13 is composed of four portions. As the key is turned tongue 11 leaves portion "a" and engages helical portion "b" to withdraw the bolt. Further rotation moves the nose 9 of stem 7 over the shoulder 8"' of projection 8. At this point tongue 11 is engaged with plateau "d". When rotation brings the ramp "c" into contact with tongue 11 the stem portion is forced down to hook nose 9 over shoulder 8"' and so hold the bolt in the withdrawn position. When the key rotates the barrel back to the locking position the nose 9 prevents the bolt sliding back until the recess in the barrel is in line with push member 4. Then when the key is removed spring 5 urges member 4 into the recess, toe 4" lifts the nose 9 upwards to disengage it and spring 12 sends the bolt into the locked position.
