Filed: 1929-05-29
Abstract: 334,217. British Celanese, Ltd., and Miller, B. E. M. May 29, 1929. 2, 4, 6-Tribromaniline and its acidyl derivatives. - Pure 2, 4, 6-tribromaniline is prepared by subjecting the crude material to sublimation, preferably at a temperature of 160‹-165‹ C. By the action of acidylating agents such as acetyl chloride or other acetyl halide, or acetic anhydride, acidyl-2, 4, 6-tribromanilides are readily obtainable in substantially pure form. The preparation of 2, 4, 6-tribrommonoacetanilide and 2, 4, 6-tribromdiacetanilide are given by way of example. When incorporated in compositions of matter containing cellulose acetate or other cellulose derivatives, the purified tribromdiacetanilide produces practically no discoloration, and when employed in quantities of as much as 10 per cent of the cellulose derivative, to reduce inflammability, shows no signs of freezing out even after exposure to temperatures below 0‹ C. Specification 319,073, [Class 2 (ii), Cellulose &c.], is referred to.

Title: Improvements relating to change-speed mechanism for driving machine tools
IPC: B23Q5/14
Filed: 1939-06-09
Abstract: 530,324. Variable-speed gearing. WARNER & SWASEY CO. June 9, 1939, No. 16919. Convention date, June 16, 1938. [Class 80 (ii)] Change-speed mechanism for driving machine tools comprises spur gearing as shown in Fig. 2 arranged between a drive shaft 24 and the work spindle 22, as of a lathe, changing of the gears being facilitated by clutching in a slow speed drive, comprising, for example, bevel gears 51, 52 and worm gearing 54, 55, before effecting the change. The main drive is effected through a clutch member 27 movable axially to engage clutch members 25 or 26 for forward and reverse driving through gears 28, 29, 30 or 32, 33 respectively. The gears 30 and 33 are on a lay shaft 31 .on which are slidable three gears 34, 35, 36 co-operating with three other gears 37, 38, 39 on a shaft 40. The gear 39 engages a gear 41 on a sleeve 42 rotatable on the work spindle 22, the gear 41 and a second gear 43 on the sleeve cooperating with two-speed gears 44, 45 on another lay shaft 46, which carries two further speed gears 47, 48 co-operating with gears 49, 50 fixed to the work spindle 22. Twelve speeds for both forward and reverse driving are thus obtainable. Before changing the gears, the main clutch 27 is moved out of action, and an auxiliary clutch 56, 57 for the slow drive is brought into action, the main clutch being re-engaged and the auxiliary clutch disengaged when the change has been effected. The clutches are operated by a lever N, Fig. 4, connected to a shaft 58 which carries an arm 60 operating the clutch member 27. A double-armed lever 65 on the shaft 58 operates the clutch member 57 through the arms 76 of two bell cranks 73, 74, which together with links 71, 72, form a double toggle mechanism connected to the clutch member 57, the lever 65 having claw-shaped ends 66 engaging the arms 76. When the lever N is in the position shown in full lines, both clutches are disengaged. With the lever in position C shown in dotted lines, the clutch 56, 57 is engaged so that the speed gears, operated by levers 83, 89, 90. may be changed. The lever is then moved to position F to release clutch 56, 57 and engage clutch 26, 27 for the forward drive. When changes of speed are desired, the lever is first moved back to position C, and then again to position F after the change has been made. Similar positions shown at CR and R give the corresponding operation for reversed drives. In a modification, the lever arms 60, 65 are replaced by a three-armed lever as shown in Fig. 12, one arm 92 actuating the main clutch, and the other arms 93, 94 being connected to the auxiliary clutch member 57 through slotted toggle arms 95, 97.

Title: Photographic silver halide colour material
Inventor: GROET NICHOLAS HERMAN
IPC: G03C7/305
Filed: 1969-04-01
Abstract: 1,269,075. Photographic silver halide colour material. EASTMAN KODAK CO. April 1, 1969 [April 1, 1968], No. 16984/69. Heading G2C. A photographic emulsion comprising lightsensitive silver halide grains dispersed in a hydrophilic colloid binder contains three non- diffusible coupling compounds which react with the oxidation products of a primary aromatic amine colour developing agent to form a non-diffusible dye, one coupling compound being a colourless coupler, one being a coloured coupler and the third being a development-inhibitor-releasing coupler having a monothio group in its coupling position which, when the coupler reacts with the oxidation products of a primary aromatic amine colour developing agent, forms a diffusible mercaptan development inhibitor. The coupling compounds may be incorporated in the emulsion as a solution in finely divided particles of a waterinsoluble coupler solvent (e.g. tricresyl phosphate, 2, 4-di-t-amylphenol and di-butylphthalate). Many examples of the various couplers are listed. The coloured coupler corrects the colour of the dye image formed by the colourless coupler and the development-inhibitor-releasing coupler improves sharpness, promotes desirable interimage effects and reduces fog caused by release of the azo group from the coloured coupler.
