Title: Improvements in the rapid heating of lubricating oil in internal combustion engines
IPC: F01M5/00
Filed: 1937-03-24
Abstract: 477,939. Heating lubricant for internal-combustion engines. MORTIER, H. March 24, 1937, No. 8706. Convention date, July 22, 1936. [Class 12 (iii)] To permit of the rapid heating of the lubricating-oil for internal-combustion engines, the oil reservoir A is traversed by a tube B having orifices C, D, at opposite ends. Above the orifices D is a throttle E controlled by a thermal element F. An oil return pipe G from the engine extends into the tube B and has orifices I at the level of the orifices C. The oil lead J, O, to the engine includes a heater K. The temperature of the oil at R, Q, is indicated by a double-reading thermometer P. A filter L is included in the heater K. At low temperatures, as at starting, the throttle E is open and a small quantity only of lubricant is circulated. The returned oil does not mix with that in the reservoir A but passes directly through the tube G and throttle E back to the engine. When the oil reaches a certain minimum operating temperature, as indicated by the thermometer P, the heating is cut off manually or automatically. Thereafter, as the oil warms up, the throttle E gradually closes so that some of the returned oil passes through the orifices I, C, to the reservoir A, and fresh oil passes from the latter through orifices D to the outlet J. When the oil reaches the temperature for proper working of the engine, the throttle E is completely closed and all the returned oil passes into the reservoir A. Should the oil temperature fall, the throttle E opens.
Patent GB-332267-A (GB)
Title: Improvements in and apparatus for the manufacture and production of esters
IPC: C11C3/02
Filed: 1929-03-18
Abstract: 332,267. Johnson, J. V., (1. G. Farbenindustrie Akt.-Ges.). March 18, 1929. Esters of higher fatty acids with glycerol are produced by causing the acid and the alcohol to flow in the liquid phase and in a continuous manner, over solid bodies possessing a large superficial area, while heating, and at a pressure below atmospheric pressure, if desired in the presence of known esterification catalysts. The temperature of the reacting liquids may be increased in the direction of flow of the liquids under treatment, and the component of lower boiling point may be initially employed in excess. Esterification catalysts, as for example alumina, active carbon, salts of the higher fatty acids as described in Specification 302,411, zinc chloride, or mineral acids may be present. In one form of the apparatus shown in the drawings for conveying out the process tower T is provided with two inlet pipes J<1> and J<2>, of which J<2> reaches down to the bottom of the middle zone 2 of the tower. The tower is charged with bodies F' possessing large superficial area, such as rings, balls or lumps of glass, porcelain, coke, or pumice. The heating means H, which may be internal or external, divide the tower into zones. The tower is also provided near its top with an outdet C which may be connected with a source of vacuum, and an outlet D near the bottom. In an example, olive oil fatty acid containing 0.1 per cent of tin oleate and glycerol are introduced into a tower filled with granular coke and heated to a temperature of from 180-200‹ C. at 10 to 20 mm. pressure. The ester is withdrawn from the lower part of the tower. In a further example, olive oil fatty acid is esterified with glycerol in a tower in which the top zone is heated to 160‹ C., the second zone is heated to 190‹ C., and the bottom zone is heated to 220‹ C. The olive oil fattv acid is introduced into the top zone and the glycerol into the middle zone. The pressure prevailing is 15 mm. of mercury, and tho excess of glycerol is removed together with the water formed from the top of the tower. The reaction product is free from glycerol and consists of 96 per cent of neutral oil.
Patent GB-541335-A (GB)
Title: Improvements relating to photographic layers containing dyes
IPC: G03C1/835
Filed: 1940-05-17
Abstract: 541,335. Coloured photographic layers. KODAK, Ltd., and BEILENSON, B. May 17, 1940, No. 8824. [Class 98 (ii)] Photographic material has a layer comprising a dye-salt formed by combination of a triphenylmethane carbinol or a diphenylmethane carbinol with a colloid binder having acidic groups in the molecule. The dye-salt may form the continuous phase, or may, when the colloid binder is waterinsoluble, and particularly when it is also waterpermeable, be uniformly dispersed as a discontinuous phase in another water-soluble binder, such as gelatine. The dye-salt may be dispersed as a discontinuous phase in a light-sensitive gelatino-silver-halide emulsion, or may be used to form an antihalation layer, an intermediate filter layer in a multi-layer film, a light-filter for lenses, or a safe-light. The dye-salt may be formed by adding a solution of the carbinol of a triphenylmethane dye to a solution of the colloid binder, or may be formed by treating a coating formed from the colloid binder. Examples are given of dye-salts formed from (a) Malachite Green carbinol , and polyvinyl phthalate, (b) Malachite Green carbinol and rosin-maleic anhydride resin, (c) Brilliant Green carbinol and polyvinyl phthalate, (d) Magenta carbinol and polyvinyl phthalate, (e) and a methoxy derivative of Malachite Green and hydrolysed soft lac. The formation of anti-halation layers from (a) and (f) is described. A gelatinosilver-halide emulsion containing the dye-salt may be used in the dye-destruction process. The pH of the emulsion may be adjusted by the addition of borax. The dye-salt should retain some free acidic groups if an antihalation layer formed therefrom is to dissolve rapidly in alkaline developing solutions. More than, one carbinol, or a carbinol and a dye-base may be used in the same layer, combined either with the same or with different colloid binders. With dispersed particles, the different dye-salts may be in the same or different particles. An anti-halation layer for panchromatic material may comprise salts of both Malachite Green (or a derivative thereof) and Magenta, and for orthochromatic material may comprise salts of both Chrysoidine and Magenta. The dye-salt may be applied to a support either by coating a solution thereof and allowing solvent to evaporate, or by moulding. Specifications 482,979, 482,995, [Group IV], 492,162, 492,257, 511,180, 520,157, 529,035, and 530,618 are referred to.

Title: Method of and means for forming cigar bunches
IPC: A24C1/10
Filed: 1928-03-23
Abstract: 314,118. M³ller, J. C., (trading as M³ller, J. C., [Firm of]), and Stelzer, F. H. B. March 23, 1928. Cigar-making machines. -In a bunching device having an apron 1 in which the bunch W is rolled by a cylindrical roller 5 over a table 4, pressure is exerted on the ends of the bunch in such a manner that the tip and head respectively are formed at opposite ends in successive bunches. In one form, Figs. 1 and 3, the roller 5 is carried by a pair of levers 7 mounted on a spindle 8 and actuated by a crank pin 10 on a crank disc 11 driven from the shaft 15. The tip and head of the bunch are formed by the inclined faces 37 of blocks 20 adjustably mounted on a rod 19, the ends of which pass through slots 18 in extensions 16 of the levers 7 and are connected to the extensions 16 by springs 38. The inclination of the rod 19 is altered, after each swing of the levers 7, by bell-cranks 22 pivoted at 23 on the levers 7 and bearing against the ends of the rod 19. Rollers 24 on the bell-cranks 22 run over cams 25 pivoted at 26 and actuated through bell-cranks 28 from grooved cams 32 driven from the shaft 15. The cam tracks 31 are such that one end of the rod 19 is at the right-hand end of its slot 18 when the other is at the left-hand end, and vice versa. In a modification, the rod 19 carrying the blocks 20 is not inclined but is moved axially after each swing of the levers 7 by a crank, cam, or the like, and the cams 25 are fixed. In a further modification, Figs. 11 and 13, the blocks 20 are provided with rollers 39 for engagement with the cigar bunch W and are formed as nuts mounted on oppositely threaded sleeves 41, the rotation of which about a shaft 42 moves the blocks 20 axially apart along a guide rod 45. The rotation of the spindles is effected by forming on their ends pinions 43 engaging with racks 50 on the table 4. The shaft 42 and guide rod 45 are carried by bearing blocks 44, each engaging a recess 47 on the end of a lever 48 pivoted at 61 to the lever 7 and having a roller 60 at its free end in engagement with a toothed cam disc 54. The two cam discs 54 are rotatably mounted near the ends of the spindle 8 and are each rotated step by step by a pawl 52 on the adjacent lever 7, check pawls 53 being provided. The teeth of the cam discs are alternately shaped as at 56, 57, the teeth 56 of one cam disc being opposite to the teeth 57 of the other. The shaft 42 and sleeves 41 are thereby tilted, first one way and then the other, during their forward movement, in order to form the tip of the bunch first at one end and then at the other.
