Title: A timing device for producing control signals spaced by accurately determined intervals
Inventor: BENNETT ALBERT EDWARD
IPC: G04F3/02
Filed: 1950-11-17
Abstract: 695,819. Time switches. MINISTER OF SUPPLY. Nov. 12, 1951 [Nov. 17, 1950; March 3, 1951], Nos. 28124/50 and 5195/51. Class 38(v) [Also in Group XVIII] Rotation by hand through a predetermined angle of a knob 12 on a shaft 13 winds up a spring 20, rotates an escapement wheel 16, and by means of a cam arm 18 closes the circuit to a synchronous motor 22; on release of the knob 12 the spring 20 slowly returns the wheel 16 at a rate determined by the oscillation of a pallet 45 engaging the wheel 16, the oscillation of the pallet 45 being caused by a snail cam 44 driven by the motor. The motor drives the shaft 41 carrying the cam 44 by means of a dog clutch 32, 33 and at the beginning of the movement a pin 34 on the shaft 41 moves past a weighted spring blade 35, the return movement of the latter operating a bell crank lever 40, 42 and releasing a spring contact 46 to operate a "start" signal. The motor continues to run releasing the escapement wheel 16 step by step until the original position of the wheel 16 and shaft 13 is reached whereupon an arm 17 on the shaft restores the contact blade 46 operating a "stop" signal and the cam arm 18 breaks the motor circuit. Time setting is effected by operation of a knob 8 which frees a member 9 from a fixed toothed wheel 10 and allows a ring 3 to be moved relative to a fixed dial 7. The ring 3 carries a stop 19 engagable by an arm 15 on the shaft 13 and so limiting the angular movement of the knob 12. Fig. 1 (5195/51) shows a modified form of escapement in which a pallet 45a operated in the same manner as the pallet 45 is carried by a lever 60 pivoted at 63. Normally the lever 60 is held pressed against a stop 68 by a spring 66, but it can be hand operated if desired to release the escapement wheel 16a at a greater rate than that provided by the automatically operated pallet 45a. In this case the tooth 62 of the pallet 45a and a tooth 64 co-operate to form an additional pallet, movement of which releases the wheel.

Title: Improvements in or relating to combined sound and colour motion picture film and methods of making the same
IPC: G03C7/24
Filed: 1934-10-03
Abstract: 449,749. Kinematograph colour-picture films bearing sound-records. BREWSTER, P. D., 28, Gillespie Avenue, Fair Haven, New Jersey, U.S.A. Oct. 3,1934, No. 28314. [Class 98 (ii)] A combined sound-record and kinematographic colour-picture record is produced on a film by printing a series of picture images and a sound track on the same side of the film, developing the film to produce the images and sound track in silver, covering the sound track with a water-soluble protective coating, converting the silver images into a dye mordant by treatment with an iodine-bearing solution and by gaseous or vaporous acid, dissolving the coating of the sound-track, and treating the film with appropriate dye. The protective coating may be applied to the sound track before the whole film is treated with the iodinebearing solution, but according to the preferred method, the application of the protective coating follows the saturation of the film with the iodine-bearing " soak." For example, after the silver images and sound track have been developed, and after fixing and drying, the film is treated with a " soak as described in Specification 449,679 ; the formula for a suitable solution containing potassium iodide and potassium iodate is given. The excess of this " soak " is blown from the film, and the wet sound track only is coated with corn syrup, honey, or the like, to which an alkali may be added. The film is then passed for a short time into a chamber containing gaseous acid (such as the vapour of glacial acetic acid), that liberates iodine and converts the silver into the gel of silver iodide. After clearing in sodium bisulphite solution and rinsing, the picture images are dyed, the protective coating having usually been dissolved out before the dyeing treatment. Numerous substances are specified as being suitable for the protective coating. They may be applied to either a dry or wet sound track, and in some cases the coating may be applied whilst hot and cooled before the bleaching operation. Among these substances is gelatine, preferably containing an alkali. It may be applied warm and then chilled or allowed to set, being afterwards dissolved in warm water.

Patent GB-285156-A (GB)
Title: Process for the preparation of vanillin and i-vanillin
IPC: C07C45/40
Filed: 1926-11-12
Abstract: 285,156. Boedecker, F. Nov. 12, 1926. Vanillin and isovanillin are prepared by treating safrol or isosafrol at a high temperature with an alcoholic alkali and methylating the product of reaction to form a mixture of the m- and palkoxymethyl ethers which are then heated with acids to form isoeugenol and isochavibetol, which are oxidized to the aldehydes and separated in known manner. Alternatively, the mixture of isoeugenol and isochavibetol may be separated before oxidation, or may be treated so as to convert it wholly into one or other of these cornpounds. In examples, (1) safrol is heated under pressure with methyl alcoholic notash and the product is methylated with dimethyl sulphate and saponified, giving a mixture of isochavibetol and isoeugenol which are oxidized to isovanillin and vanillin and separated. The mixture of isochavibetol and isoeugenol can also be worked up almost completely into isoeugenol or vanillin bv freezing out the isochavibetol and methylating it to produce propenyl-3.4-veratrol, which if heated with alkali forms a mixture of isoeugenol and isochavibetol, the latter being extracted and added to the next batch. The isoeugenol is obtained from the filtrate by forming the benzoyl or nitrobenzoyl compounds, the acidyl compounds of isoeugenol being less soluble than those of isochavibetol. If it is desired to produce isochavibetol or isovanillin alone, the isoeugenol instead of the isochavibetol is converted into propenyl-3.4-veratrol. (2) A mixture of isochavibetol and isoeugenol obtained as above is mixed with hexahydrotoluene, and on standing in the cold isochavibetol crystallizes out; the mother liquor freed from solvent is distilled in vacuo giving mainly isoeugenol, and on treating this with benzoyl chloride isoeugenol benzoate is obtained. The isochavibetol is converted by boiling in alcoholic lye with halogen methyl into propenyl- 3.4-veratrol and this on heating with alcohol and alkali under pressure gives a mixture of isoeugenol and isochavibetol which is worked up as before. The isoeugenol may be purified by means of its sodium salt.
