Title: Improvements in locks, latches and like fastening devices
IPC: E05B65/22
Filed: 1947-08-27
Abstract: 633,024. Latches. DIMMOCK, I. Aug. 27, 1947, No. 23764. [Class 44] In a door or like latch as in Specification 511,158 wherein a catch in the form of a bellcrank lever pivoted about an axis parallel with and near to the edge of one of the door members so that at either extreme position one arm will lie within the body of that member and the other will project outwardly, a spring-urged movable abutment is held retracted from the bell-crank lever, and on pivotal movement of the latter during closing of the door the abutment is released, attains momentum, and then strikes one arm of the bell-crank to force it against the retaining stop on the other door member. A pair of supports 27, 28, Fig. 1, near the edge of the door, form the mounting for a bell-crank lever 24, Fig. 7, and a detent 39. An abutment in the form of a main bolt 29, urged into the shot position by a number of parallel tension springs 38, is housed between two metal strips 30, which being screwed to a connecting bar 31, move as a unit and constitute a security latch bolt. When the door is open, a tension spring 66 forces the arm 26 of the bell-crank to project, a spring 42 urges a claw 40 on the detent into a recess in the main bolt 29 to keep the latter withdrawn, and a compression spring 33 housed between an abutment 34 on the back plate, and a member 35 on the upper strip 30, projects the security latch. On closing side door the security latch rides over and snaps behind a pair of wedge-shaped members 62, Fig. 8, the arm 26 strikes a trip member 64, located between members 62, causing the bellcrank to rotate clockwise, and a comer contacts a projection 44 on the detent 39. The detent is consequently rotated to release the main bolt, which attains considerable momentum before striking the second arm 25 of the bell-crank, to force it against its retaining stop 63. To release the lock, a handle 50 on spindle 49 is rotated, and a follower 47 engages a projection 46 on the security latch 30. This releases the main bolt 29, which has extensions 32 contacting the security latch. A wedge 68 attached to the door, engages a wedge-shaped recess 69 in the door post, to locate the lock correctly with respect to the retaining stop. In a modification, Fig. 3, the bellcrank and detent are integral thus avoiding -lost motion between them. A pin 72, in a slot 73 in the main bolt, is engaged by a claw until the bellcrank is rotated into the position shown in chain lines. In a further modification, Fig. 14 (not shown), the bell-crank and detent are connected by gears. A modified method of projecting the bolt is described, in which a coil spring housed in a slot in the bolt acts between an end of the slot and a fixed abutment.

Title: Process for removing mercaptans and other sulphur compounds from hydrocarbon oils by treatment with hydrofluoric acid
IPC: C10G29/24
Filed: 1955-08-18
Abstract: Mercaptans and other sulphur compounds are removed from hydrocarbon oils by treating with hydrofluoric acid in the presence of a saturated ketone, or a ketone in which the only unsaturation is present in aromatic radicals.  Ketones referred to are aliphatic ketones having 3-8 carbon atoms, e.g. acetone and butanone, and ketones having a cyclic radical, e.g. acetophenone. The ketones react with mercaptans to form thioacetals which dissolve in hydrofluoric acid.  At least one mole of ketone / gm. atom of mercaptan sulphur is preferably used.  The ketone may be added to the oil before or after contacting with hydrofluoric acid; the process may be effected in the liquid phase, or the oil may be treated with ketone in the gas phase and then with liquid hydrofluoric acid.  Boron trifluoride may be dissolved in the hydrofluoric acid as described in U.S.A. Specification 2,343,841. The process may be operated batchwise, or continuously, as by countercurrent extraction.  The oil and acid phases formed in the treatment may be separated by decanting or centrifuging; hydrofluoric acid remaining in the oil may be removed by evaporation, washing with water with or without an alkaline substance such as an alkali metal hydroxide or ammonium hydroxide, or by adding a light hydrocarbon which may be removed with the acid as an azeotropic mixture.  Hydrocarbon oils containing less than 0.1 per cent of unsaturated components may be treated, e.g. hydrocarbon oils obtained by straight distillation of a crude petroleum oil; gasoline, kerosine, gas oil and lubricating oil are referred to.

Patent GB-702011-A (GB)
Title: Improvements in the processing of nickel-copper matte
IPC: C22B15/00
Filed: 1951-10-17
Abstract: Nickel carbonyl is recovered from nickel-copper matters having insufficient sulphur to bind the nickel and copper as sulphides, e.g. 20 per cent. sulphur or less, by comminuting the matte, preferably after annealing, separating the metallic copper and nickel fraction from the copper and nickel sulphide fraction, and treating the metallic fraction with carbon monoxide at pressures above 50 atmospheres and temperatures of 200 to 230 DEG C. to remove the nickel as carbonyl, which may then be reduced to metallic nickel. The copper residue is enriched in noble metals if present.  Cobalt or iron, if present in the matte may be carbonylated simultaneously with the nickel and separated by distillation or selective carbonylation of the nickel may be effected.  According to an example a nickel copper matte containing 19.4 per cent. sulphur is heated at 500 DEG C. for 72 hours, comminuted and the metallic nickel/copper fraction separated from the sulphide fraction.  The metallic fraction is treated with carbon monoxide at 200 atmospheres pressure and between 130 to 200 DEG C. whereby, after 6 hours the nickel is substantially converted to carbonyl.
