Roller inking-arrangements.-Multicolour inking-apparatus comprises inking-rollers movable into the paths of the types and shiftable for colour selection. The apparatus shown in Figs. 1 and 3 is a modification of that described in Specification 153,898 and comprises fountains 3a, 3<b> containing inks of different colour, a knife, ductor rollers 4, distributing- cylinders 8, and type-inking rollers 15, which run on the distributing- cylinders, and travel to and from the ductor rollers, and into and out of the paths of the types. The frame F of the apparatus is mounted on a track 58 and can be shifted laterally for colour selection by rocking a key-arm 43 carried by a shaft 40 which is connected by a link 38 to the frame. The inking-rollers 15 are mounted on a shaft 19 carried by spring-urged arms 18 pivoted to carrier-arms 17 on a shaft 17<v>, the arrangement enabling the inking-rollers to yield in meeting the types. The carrier-arms are reciprocated by means of a rack 6 which engages a pinion 6<c> on the shaft 17<v> and is coupled by a link 6<a> to an arm 5 on a shaft 22. The inking-rollers are reciprocated endways to distribute the ink by means of a collar 16, Fig. 1. which is splined on the shaft 19 and is provided with a pin engaging a cam-groove 10 formed in an extension of the distributing-cylinders. One of the carrier-arms is formed with teeth 17<c>, Fig. 3, for driving a pinion 4<a> in connection with the ductor rollers. The distributing-cylinders are provided with a pinion 12 engaging a driving-pinion on a shaft 36. The shafts 36, 22 have sliding-box connections 34, 24, Fig. 1, with shafts 33, 20 respectively, the shaft 33 having a pinion 32 gearing with a pinion 31 on a shaft 28, and the shaft 20 having a pinion 26 gearing with a pinion 30 on the shaft 28. The box connections enable the inking-apparatus to be shifted while maintaining connection with the shaft 28. An alternative arrangement for this purpose consists in providing pinions 30, 32 of sufficient width to remain in mesh with the pinions 26, 31 when the apparatus is shifted. The pinion 30 is driven by a rack 49 connected by linkage 50, 51, 52 to a spring-urged lever which is released and restored in the manner described in the above-mentioned Specification. The apparatus can be rendered inoperative for stencil-cutting, by blocking the spring-urged lever by means of a hook formed on an arm 61, Fig. 1, carried by a shaft 54 which can be rocked by a key-arm 55. The apparatus may be applied to the type-lever machine described in Specification 153,324.

Title: Process for the manufacture of saccharosonic acids and their salts
IPC: G03C5/30
Filed: 1933-12-27
Abstract: Saccharosonic acids are obtained by treating esters of osonic acids, such as glucosonic acid and similar acids (such as are obtained by the cleavage of osazones of reducing sugars and oxidizing the osones) or their lactones with salts of weak acids, fixed alkalies, or alcoholates, the reaction medium in the case of using fixed alkalies being kept as neutral as possible to suppress normal saponification. Instead of the isolated esters of osonic acids there may be used the crude alcoholic solutions formed in their preparation or the crude potassium salt of diacetone glucosonic acid as obtained by the oxidation of b -diacetone fructose.  In examples: (1) glucosonic acid methyl ester is treated with sodium bicarbonate at 60--70 DEG  C., the sodium salt of saccharosonic acid crystallizing on cooling, and the free acid may be obtained by treating this with sulphuric acid; (2) the sodium salt of glucosonic acid is boiled in methanol and the equivalent quantity of sulphuric acid is added; the equivalent quantity of a solution of sodium carbonate or hydroxide is added gradually, and the sodium salt of saccharosonic acid separates; (3) the potassium salt of diacetone glucosonic acid is heated to 50 DEG C. with methanol and sulphuric acid and the potassium sulphate is separated; the solution is diluted and barium or calcium carbonate is added at 60--70 DEG  C.; the barium or calcium is then removed with the equivalent quantity of sulphuric acid, and the solution is concentrated to crystallization; (4) d-glucosonic acid methyl ester is added to a solution of sodium in methyl alcohol and heated at 50--60 DEG  C.; a crystalline precipitate is removed, and the filtrate is diluted with water which precipitates the sodium salt of d-glucosaccharosonic acid; the first crystalline precipitate is dissolved in water and a further quantity of the saccharosonic acid salt crystallizes on standing.  The products are antiscorbutics, ascorbic acid being of the same class.  They may be used as carbohydrate substitutes in diabetes, as disinfectants, and as photographic developers.  The Specification as open to inspection under Sect. 91 includes the use of acylated lactones of osonic acids as starting materials and two further examples in which glucosonic acid methyl ester is heated with pyridine and triacetyl glucosonic acid lactone is heated with a solution of sodium in methyl alcohol. This subject-matter does not appear in the Specification as accepted.

Title: Process for the separation of organic compounds
IPC: B01D53/02
Filed: 1956-08-23
Abstract: <PICT:0871495/III/1> Mixtures of organic compounds are separated into their components by treatment in two columns A, B, arranged in series and may be inclined or vertical, through which an eluent gas is admitted to the bottom of column A and rises to the top and then flows upwards through column B; simultaneously there flows in counter current with the gas a solvent liquid which is admitted to the top of column B and flows downwards to the bottom from which it then passes downwards through column A.  The mixture to be separated is admitted at any point in column A or B, and the rates of flow of eluent gas and solvent liquid, and/or the temperature are adjusted so that at least one component passes to the top of column B and another to the bottom of column A.  The two columns may be combined to form a single unit and are packed with inert material to present a large surface to the flowing liquids.  The mixture may comprise a close boiling range mixture, e.g. hydrocarbons, an azeotropic mixture, petroleum ethers or essential oils.  As eluent gas there may be used hydrogen, methane, air, steam or carbon dioxide.  As solvent liquid, ketones, paraffins, ethers, esters, nitriles, glycols, or silicones.  In the Figure, two packed zones SC SH are arranged in series and the temperature of SH is higher than that of SC; eluent gas is fed in at line 1, and solvent liquid at line 3; the liquid mixture is admitted through a line 5 where the two zones meet.  One component passes out at the top with the eluent gas at 2, and a second component in the liquid solvent at the bottom through line 4.  The liquid and gas flow slowly through the column.  In examples, mixture of isopentane and n-pentane are separated using air and kerosene. Specification 871,494 also is referred to.

Abstract: 833,384. Controlling vehicles. PERFECT CIRCLE CORPORATION. Nov. 25, 1957 [Dec. 11, 1956], No. 36633/57. Class 79(5) [Also in Group XXXV] In a speed control arrangement for an automotive vehicle having a driver-operated throttle control member, electric driving means for producing "feel" in the control member or maintaining the vehicle speed constant are energized through an auxiliary member movable with the control member in response to the speed of the vehicle and to the movement of the auxiliary member to a position corresponding to a predetermined speed. The housing 34 of the control unit 20, Fig. 1, is mounted on a bracket 21 from the fire-wall 23 of an automobile and has a lever 46 engaging throttle rod 47, the latter being operable by a pedal 26 against the action of a spring 28. Motor 51, the circuit of which is in Fig. 8 (not shown) is arranged when contacts 66, 67, Figs. 3, 5, 6 are closed by the depression of a pedal 26 to a point corresponding to a predetermined speed to apply a torque to lever 46 to oppose the manual depression force through a gear chain 52, 53, 55, 56, and a pin 61 on a rotatable member 41 engaging the end of a slot 60 in gear sector 52, the member 41 being secured to a rotatable shaft 42 to which the lever 46 is secured. Contact 67 is positioned by a lever 100 in response to the action of the bog-weights 81 of a spring controlled governor, the position for a predetermined speed being manually preset by a bowden cable 85, 113, acting on the governor spring through a slide 107 which is mounted between rollers 111, 112. The contacts are operated through springs 102, 104 to prevent damage when the pedal is pushed past the point at which resistance is provided. Under these conditions the motor is stalled and provides maximum opposing torque, and spring 50 on the operating rod is compressed. The slot 60 allows the pedal (when released) to return under the action of spring 28. The motor armature 51 is connected to a tapping in the field winding so that rotation in opposite directions may be obtained by differentially energizing the two field portions. For automatic speed control of the vehicle, gear sector 52 is solidly coupled to lever 41 by an electromagnet 120 the circuit being manually operated by a switch 133 on the steering column and self holding through contacts 134, 135. The throttle lever is then held in a position to give the desired vehicle speed irrespective of gradient by the motor 59 which drives the rod one way when the governor, which is coupled to the speedometer, operates contacts 66, 67, due to overspeed and in the reverse direction when the speed falls to a value below the desired speed and contacts 150, 151 are closed. The speed control circuit is deenergized by a switch operated by actuation of the brake pedal.

Title: Improvements in or relating to the production of substantially oil-free wax and dewaxed oil from wax-bearing lubricating oil stock
Inventor: GROSS HOWARD HALCOMB
IPC: C10G73/06
Filed: 1954-12-21
Abstract: Wax-bearing lubricating oil is dewaxed by treating with a liquid which is a solvent for oil but not for wax at dewaxing temperatures and in which water is partially miscible, filtering to obtain dewaxed oil dissolved in solvent and primary wax containing some solvent and oil; mixing the primary wax with wet solvent, filtering to obtain secondary wax of low oil content and a filtrate comprising solvent and a little oil, at such a temperature that the moisture in the solvent is crystallized and separated as ice with the wax; and recycling the dry filtrate to the first dewaxing step.  The secondary wax may be heated to, for example, 130 DEG F. and the liquid wax separated from the water.  The solvent recovered from the primary dewaxed oil may be separated by steam stripping and may be recycled to the secondary dewaxing zone.  Solvents referred to are mixtures of aromatic hydrocarbons such as benzene and toluene with ketones such as acetone, methylethyl ketone, methylisobutyl ketone, methyl normal butyl ketone and methyl normal propyl ketone, aldehydes, chlorinated hydrocarbons, such as methylene chloride, esters, such as propyl and amyl acetate and low boiling paraffins such as pentane and hexane; single solvents may also be used.  An example is given of dewaxing a wax distillate oil with methylethyl ketone and toluene; a dewaxing temperature of -10 DEG F. is used in both dewaxingsteps and the wet solvent contained 1 per cent of water.
