Title: Improvements in or relating to Apparatus for Cooling Chocolate, Cocoa Butter, or other Materials which Coagulate when Cold.
Inventor: SAVY EMILE LOUIS ALFRED
IPC: A23G7/02
Filed: 1919-02-18
Abstract: 124,196. Savy, E. L. A. March 13, 1918, [Convention date]. Cooling-chambers.-In a machine for cooling chocolate, cocoa butter, or other materials which coagulate when cold, two or more endless conveyers 1, 1<1>, made of laths of wood or metal, are arranged on brackets 3 in a cooling chamber 2, and are adapted to be driven at different speeds by motors. Arranged above and between the surfaces 10, 11, of the conveyers is a series of fans 7, 9 mounted on vertical shafts 6 driven through gearing from a shaft 31. The shafts 6 may be placed at a distance apart, or arranged so that the blades of the fans overlap, and the air is caused to circulate right and left by means of a central fan. In order that the temperature of the moulds may be adjusted to that of the room before they leave the machine, a partition 18 forms a second chamber 17 in continuation of the cold chamber 2, and the passage of the conveyers is permitted by flexible brushes 19. In this second chamber, fans 16 are mounted in the roof and are adapted to draw in the surrounding air of the room, passing it over the moulds; the air is finally expelled, by lower fans 16<1>, through openings 25 leading to the room. The moulds are removed through openings 22, 23. The above described machine is combined with the usual conveyers 34 for evacuating full and empty moulds.

Patent GB-847861-A (GB)
Title: Flow meter
Inventor: BRAND ALFRED THOMAS
IPC: G01F15/00
Filed: 1958-02-07
Abstract: 847,861. Flow-meters. BRITISH OXYGEN RESEARCH & DEVELOPMENT Ltd. Feb. 5, 1959 [Feb. 7, 1958], No. 4066/58. Class 40 (1). [Also in Groups XXVI and XXXIV] In a flow-meter of the type wherein a liquid flows through a working chamber and so causes cyclic movements of a flow-responsive member, the latter is made of polytetrafluoroethylene (or of a metal impregnated therewith) and is not connected mechanically with the recording equipment; the flowmeter is thus suitable for liquds having boiling-points substantially below atmospheric temperatures, e.g. liquid oxygen. In Fig. 1 the liquid enters at 11 and passes through an aperture 16 into the working chamber 13 where it acts on the radial diaphragm of a rotary piston 18 and causes the central pin 19 of the latter to travel in a circle around studs 23, 25 attached respectively to the bottom and top of the chamber. The piston itself is made of polytetrafluoroethylene, or of aluminium, brass or bronze impregnated therewith, and the central pin, which is of magnetized steel, is prevented from rubbing directly on the studs by providing the latter with an exterior lining 27 of polytetrafluoroethylene. An iron pin 29 projects through the top of the casing and forms the core of an inductance coil 30 so that a voltage pulse is induced in the coil once per revolution of the piston. This pulse is amplified, squared and fed to a unit (not shown) which measures the amount or rate of flow. In a modification (Figs. 2 and 3, not shown), the pick-up is by means of a mild steel pin sunk in the peripheral wall of the piston co-operating with a permanent magnet via a pin around which the coil is wound. The pulses can be generated photo-electrically or capacitatively instead of inductively.

Patent GB-623114-A (GB)
Title: The production of 2-hydroxy-4-aminobenzoic acid
Filed: 1947-02-17
Abstract: 2-Hydroxy-4-amino-benzoic acid is prepared by diazotizing 2-amino-4-nitrobenzoic acid by treating with nitrous acid in concentrated sulphuric acid with cooling, diluting the resultant solution with water and boiling in the presence of a copper salt (preferably copper sulphate) to form 2-hydroxy-4-nitrobenzoic acid, which is reduced to 2-hydroxy-4-amino-benzoic acid. Preferably, the boiling stage is carried out by pouring the diazotized solution into warm water in which copper sulphate is dissolved and heating rapidly to 110 DEG  to 120 DEG  C.  In an example, 2-amino-4-nitrobenzoic acid is dissolved in sulphuric acid, treated with sodium nitrite, the resultant solution is poured into warm copper sulphate solution and is boiled, giving 2-hydroxy-4-nitrobenzoic acid which is reduced to 2-hydroxy-4-aminobenzoic acid by treating with hydrogen in alcohol in the presence of platinum oxide or by means of tin and concentrated hydrochloric acid.  The Specification as open to inspection under Sect. 91 comprises also the preparation of derivatives of 2-hydroxy-4-amino-benzoic acid such as 2-hydroxy-3-methyl-4-aminobenzoic acid, 4-hydroxy-6-aminoisophthalic acid and 2-amino-4-nitro-x-sulphobenzoic acid by the process described above.
