Abstract: 348,507. Colour photography. DEGENHARDT, A. F., 37, Mortimer Street, London. Nov. 12, 1929, No. 34480. [Class 98 (ii).] In a process for colouring the images on a film having an emulsion coating on each side, the images on one side are treated by floating the film over bleaching and dye baths, the bleaching bath being so composed that the dye images produced are unaffected by another bleacher, and the film is then immersed in a second bleaching bath and a dye bath to colour the images on the other side. In an example the first bleacher comprises potassium ferricyanide, potassium iodide, potassium bromide, acetic acid and ferric ammonium sulphate, the images on this side being dyed blue or blue-green. The second bleacher may comprise potassium iodide, iodine and citric acid, the images being dyed orangered. Ammonium bichromate may be added to the first bleacher. It is stated that the first bleacher has a slight toning effect on the silver images.

Filed: 1920-12-08
Abstract: 176,514. Lanchester, F. W. Dec. 8, 1920. Change-speed gearing; disconnectible gearing; transmission gear of invariable ratio.-Comprises friction driving-gear in which the road wheels are driven through rollers which engage the periphery of the wheels and through which the weight of the vehicle is transmitted to the wheels, the rollers being provided with concave rims to maintain the relative lateral positions of the wheels and the body of the vehicle. The load is transmitted to the wheels through rollers D, E which bear on the wheels, the rollers D being mounted on the engine or driving shaft S. Push-bars M are connected to the axle A and a pedal R so that when the pedal, or a hand-lerver N, is operated the bars are pushed backward and move the road wheels away from the driving rollers D thus disengaging the drive. Further operation of the pedal forces the road wheels against fixed brakeblocks P. The bars M may be detachably connected to the axle, so that when the body is raised it is free from the road wheels and the axle. In a 'modification, the idle rollers E are replaced by links pivoted to the body and to the axle, and the rollers D drive either through friction rings encircling the rollers or through bands passing round the driving-rollers and other rollers, so that slip may take place between the bands or rings and the rollers, instead of between the rollers and the road wheels. According to the Provisional Specification an additional pair of smaller driving- rollers may be provided to give a lower speed ratio..

Abstract: 1,201,219. Electric selective signalling. HONEYWELL Inc. 22 July, 1968 [24 July, 19671. No. 34786/68. Heading G4H. To effect a coarse and fine digital measurement of the phase difference between two cyclic signals A, B the cycle of each of which includes a period when a carrier is modulated by a continuous wave component followed by a period of silence followed by a pulse of unmodulated carrier the A and B wave components are fed by a wave synchronizer pulsed by a clock source 56 (Fig. 1) to a sine wave counter control 16 which enables a fine wave counter 20 to accumulate clock pulses during the time interval between a B and A wave, the result of the previous measurement being held in an output fine register 56. Similarly a fine pulse counter 32 accumulates pulses between two pulse component signals, overflow pulses being accumulated in a coarse pulse counter 30. If a pulse valid signal is received the contents of coarse pulse counter 30 are transferred to coarse wave counter 38 and at the end of the cycle the contents of fine pulse counter 32 are compared with fine wave counter 20 to increment or decrement counter 38 when counter 32 has a large count and counter 20 a small count or vice versa. If a pulse valid signal is not received the contents of coarse wave counter 38 are adjusted if necessary by comparing the previous fine measurement stored in register 56 with the new measurement in counter 20 the count in counter 38 being incremented or decremented by one when the counts differ substantially depending on the relative values of the contents of counter 20 and register 56. The fine pulse counter 52 accumulates its count positively or negatively depending on whether a B or A pulse is received first. The apparatus may be used for measuring the direction of travel of acoustic waves received by three hydrophones, the hydrophones being connected in pairs to the described apparatus.

Title: Improvements in or relating to the distillation of solid carbonaceous or oil bearingmaterials
IPC: C10G1/02
Filed: 1927-12-23
Abstract: 306,654. Nielsen, H., and Laing, B. Dec. 23, 1927. Coking processes. - Oil-bearing solids such as coal-tar sands, oil shales, or the like, are distilled in a current of hot gas, and are first preheated to a temperature above that at which the heaviest oil fractions in the vapours are liable to condense, for example 100‹ to 250‹ C., according to the volume of gas passing through the retort, said temperature being an inverse proportion to the quantity of oxygen containing constituents in the charge. When the distillation takes place in a controlled volume of hot inert gas of 45,000 cubic feet per ton and the volume of oil recovered is about 20 gallons per ton, the material is preheated to 200‹ to 250‹ C. When the volume of gas used is 100,000 cubic feet, the preheating temperature is 150‹ C. The temperatures of the retort dust extractor &c. do not fall below 100‹ to 150‹ C. until actual condensation of the oil vapour is desired. Specification 287,381 is referred to, and Specification 287,037 also is referred to in the Provisional Specification.

Patent GB-823180-A (GB)
Title: Improvements in the production of epoxidic compounds
IPC: C07D303/22
Filed: 1957-11-14
Abstract: Epoxidic compounds are produced by treating with peracetic acid an ester or ether of an unsaturated alcohol of the general formula <FORM:0823180/IV (a)/1> in which R represents hydrogen or an alkyl radical and R1 an alkyl radical.  Suitable alcohols for the formation of the ether and ester starting materials are those in which R represents hydrogen or methyl, and R1 is methyl, ethyl or propyl. They may be obtained by dehydration of the corresponding 1.3-diols or by partial hydrogenation of unsaturated 2-alkyl branched aldehyde. By pyrolysis of the diacetates which are formed by acetylation of the 2-alkyl branched 1,3-diols (readily accessible by aldol condensation and subsequent hydrogenation) there are obtained the mono-acetates of unsaturated 2-alkyl branched alcohols of the above formula.  These acetates may be readily re-esterified especially with methyl esters. After saponification, they may be esterified with monobasic or polybasic acids or acid anhydrides, for example acetic acid, adipic acid, phthalic acid, epoxytetrahydrophthalic acid, phosphoric acid, mono- or di-alkylphosphoric acid or sulphonic acids to esters, or reacted with alcohols, glycols, polyglycols, thioglycols, diethanolamine or diphenylolpropane to ethers.  These ethers and esters are then epoxidized by dripping into peracetic acid in glacial acetic acid or acetone at 30 DEG  to 35 DEG  C. and then stirring for 5 to 6 hours at the same temperature.

Abstract: 1,048,290. Ironing machines. SIEMENS ELECTROGERATE A.G. Sept. 9, 1963 [Sept. 10, 1962; Jan. 8, 1963; March 20, 1963; May 16, 1963; June 1, 1963], No. 35536/63. Heading D1A. In an ironing machine comprising a rotatable roller W and a heated shoe Mu movable towards and away from the roller, drive mechanism for the roller and shoe from a single reversible electric motor Mo includes counter running free-wheel devices F 1  and F 2  so that on rotation of the motor in one direction the roller is rotated whilst on rotation in the other direction the shoe is actuated through a crank and lever A. As shown the switch Sch is loaded by a spring F for roller rotation but on being depressed reverses the rotation of the motor for shoe actuation which is also controlled by limit switches to stop the shoe in its end positions for the insertion or pressing of the garments. In an alternative switching arrangement, Fig. 4 (not shown), switch 6 is actuated by a brief pressure at 10 on lever 7 to operate the shoe 5 through an eccentric 12 by reversing the motor Mo. The switch 6 is held in this actuated position by a cam disc 9 for about a half revolution thereof when it is released for roller actuation again with the shoe in the lifted position. On another brief operation of the lever 7 the shoe is re-applied to the roller and then the roller restarts. In another arrangement, Fig. 5 (not shown), a switch 16 must be continuously depressed for the ironing operation. If it is released the shoe is lifted after which a motor reversing switch is actuated to restart the roller. The switch 16 must be actuated again to apply the shoe. This ensures that the apparatus cannot be left with the heated shoe applied to the roller. The switch 16 may be released momentarily for a slight lifting of the shoe for adjustment of the work and then depressed for continuation of the ironing. In certain cases it may be necessary to provide a non-reversible drive from the motor or a motor braking device so that the motor stays stationary when switched off. The motor Mo may be mounted within the roller 1, Fig. 10 (not shown), and the gearing actuating the shoe 5 within arms 63, 64 supporting the roller.

Title: Improvements relating to dry-pipe fire-extinguishing sprinkler systems
IPC: A62C35/64
Filed: 1928-12-03
Abstract: 327,436. Woosnam, A., (Automatic Sprinkler Co. of America). Dec. 3, 1928. Sprinklers, automatic.-A dry pipe sprinkler system in which the main valve opens as usual in case of a fall of pressure in the distributing pipes consequent upon the opening of a sprinkler head, is provided with means whereby a rise of pressure in the air pipes, or in a supplemental piping in the fire zone, due to heating thereof. will also cause the main valve to open in advance of the opening permitted by the fusion of a sprinkler head. As shown, the casing 3 for the dry-pipe differential valve 4, 5 has a neutral chamber 3<1>, and the air pipe 7 is connected by a pipe 9 to a casing. This consists of two chambers 10, 11 separated by a diaphragm 13 and normally maintained at the same pressure by a " bleeder " device 12. The chamber 3<1> is connected to the chamber 10 by a pipe 20 closed by a valve 19. If the air pipes, such as 7, are heated by a fire before the fusible heads 8 open, the pressure in chamber 10 rises and the diaphragm. is lifted. This opens the valve 19 through a rocker arm 16 and weighted lever 17, allowing air under pressure to pass to the chamber 3<1>, causing the main valve 4, 5 to open. If a head 8 opens first, the pressure in chamber 10 falls and the diaphragm 13 moves down, again opening the valve 19. The air entering chamber 3<1> will now accelerate the normal opening of the main valve. An air pump 22 used for replenishing the pressure in the air pipe system is connected by a pipe 25 to a chamber 26 separated from the chamber 10 by a diaphragm 27 and a valve 31. When the diaphragm 27 is distended by pressure in the chamber 26, it carries forward a rod 28 which opens' the valve 31 by means of a bellcrank 30. The rod 28 also serves to lock the rocker 16 against movement, so that increased pressure at this time in the chamber 10 cannot cause the diaphragm 13 to open the valve 19. An extension 34 carried by the diaphragm 13 serves to prevent the retreat of the rod 28 until the diaphragm is in its normal, central, position. Specifications 326,141, 326,142, and 330,254 are referred to.

Abstract: 1504900 Steering vehicles by engagement with guide rails TRANSPORTS - RECHERCHES ETUDES ET GROUPEMENT D'INTERET ECONOMIQUE 28 Aug 1975 [13 Sept 1974] 35554/75 Headings B7H and B7L A transport system comprises a guidance member 3 for engagement by a follower 6 carried on a vehicle to be guided therealong, the member 3 being of substantially circular crosssection and being mounted in a channel 26 at a track fork. At the fork, the member 3 broadens and then divides into respective guidance members for each branch track, the broadened member being of reduced height as shown in Fig. 5 so that one side 12 of the follower 6 rides over the broadened member at the fork, the follower having been tilted to select a route at the fork. The internal surface of the follower is part-circular and complementary to the circular section of member 3, the tilting being effected by an actuator 20 which pivots the follower about the axis of the circular surface. In the fork region, Fig. 5, the lowered side 13 of the follower engages a peripheral portion 28a of the broadened member 3, lateral portions 28a and 29a of which are curved to form parts of respective circles having the same diameter as the circular section of member 3. At the same time, external surfaces 22 and 23 of the follower engage the side wall 24 and base 25 of the channel 26, respectively, so that the tilted follower is securely retained on the guidance member throughout the passage of the vehicle through the fork.

Title: Improvements in or relating to a method of testing for lead-210
Inventor: LOVERIDGE BRIAN ARTHUR
IPC: G01T1/16
Filed: 1961-10-03
Abstract: A process for testing for lead-210 comprises precipitating the lead as sulphate, dissolving the lead as chloride, separating the lead by an ion exchange process, and, after a known delay counting the beta particles from the daughter bismuth-210 through a shield stopping beta particles from lead-210 and alpha particles from polonium-210. To test an effluent from radio-chemical laboratories or processing plants, a sample of the effluent is treated with sodium sulphate in the presence of lead and strontium carriers; the sulphate precipitate is treated with sodium carbonate, dissolved in hydrochloric acid, and the solution passed through an ion exchange column; lead is eluted from the column with water and precipitated as chromate.  After five days the bismuth-210 formed is counted through an aluminium absorber. In order to purify the bismuth-210 further, the precipitate is disolved in hydrochloric acid with a bismuth carrier, the solution passed through another ion exchange column, and the lead is removed by washing with water.  Bismuth is eluted with sulphuric acid, precipitated as phosphate, and counted.
