Filed: 1947-12-02
Abstract: 652,626. Calculating-apparatus. BELL PUNCH CO., Ltd., and WEBB, C. F. Dec. 2, 1947, No. 31863. [Class 106 (i)] In a calculating machine having keys separately operable to move a rack distances which correspond to the numbers allocated to the keys and thereafter to cause the said rack to be moved into engagement with a pinion and move the same a corresponding distance to actuate a totalizer wheel, means associated with each pinion normally locks the same positively against rotation and, prior to a pinion being set in motion as the result of the actuation of a key, automatically releases the said pinion. Depression of a key 1 depresses a key-bar 2 which, through links 3, 4, 5, 6 and 7 raises a rack 8. When the key is fully depressed, a known mechanism moves the rack 8 forwardly into contact with a totalizer pinion 9 and a spring 18 connected with this mechanism rocks a lever 12 counter-clockwise about a pivot 17, the pivot connecting the links 6 and 7 having moved from the path of the end of the lever 12. The latter carries at its other end a lug which is thus moved from the highest part of a cam surface 19 formed on a pawl 11 to enable a spring to withdraw the pawl from its normal position in which it locks the pinion 9. When a disc 13 of the transfer mechanism rotates, pins 13a therein co-operate with projections 12a of the lever 12 to rock it clockwise, thus allowing the pawl 11 to be withdrawn. In a zeroizing operation, the pawls 11 are moved axially of the pinions 9, by means not shown, on operation of a hand lever. Specifications 514,289, 514,290, 514,291, 516,535, 522,721 and 652,627 are referred to.

Abstract: 761,878. Digital electric calculating-apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 17, 1954 [Nov. 17, 1953], No. 31877/53. Class 106 (1). In a digital computing machine binary numbers are stored in an interlaced manner on a drum, the binary words ARTIST, BUFFER, CONVOY, and DECIDE being stored as shown in Fig. 2, reading anti-clockwise, and a combined binary counter and shifting register is provided for adding at least two-of the numbers as they are read from the drum. For the addition of two numbers as shown, gates G<SP>1</SP>, G<SP>2</SP> and G3 are suitably controlled by control pulses read from the drum by a head 23, so that only the digits of the selected words pass through the gates G<SP>1</SP> and G<SP>2</SP> from the reading head 22 and so that the digits of the sum, each of which is stored by a flip-flop ST for one sector time, are recorded in a selected position on the drum. As the lowest order (2‹) digits of the selected words to be added are read they are passed to a binary counter AD, the contents of which are shifted one stage in the direction of decreasing significance at the end of each sector time, the least significant digit being passed to the flip-flop ST and the remaining digits (if any) . acting as carry digits. In this way addition of two or more numbers takes only one revolution of the drum and no auxiliary storage devices are needed.

Title: Apparatus for use in displaying advertisements, notices, pictures, and the like
IPC: G09F11/23
Filed: 1923-12-20
Abstract: 226,040. Johnson, P. L. Dec. 20, 1923. Coloured and opaque liquids, utilizing; reel and endless-web apparatus.-In advertising &c. devices in which words, letters, pictures, signs, &c. are carried on levers, bars, bands, &c. immersed in an opaque liquid contained in a tank having a transparent window to and from which the letters &c. are moved to render them visible and invisible, several sets of levers, &c. 12 are provided each operated independently by a member d journaled in the sides f of the tank and furnished with an inclined or helical surface. The letters 16 are on plates 15 ball-jointed on the levers 12 and embracing them with projections 17. The levers 12 hang loosely from rods 10 and have projections 18 which ride on the surface of a hollow cylinder 1 secured to the shaft d, or fall into a slot the walls 3, 4 of which are respectively parallel to the shaft d and helically disposed thereto. Instead of the slot, bars may be secured to the surface of the cylinder 1. Fixed at each end of the shaft d is a cam 5 which engages a nose 25 on a lever 23 pivoted at 24 and carrying a projection 22 which forces round an extension 21 of a lever 19 pivoted one at each end of the rod 10. A rod 20 connecting the levers 19 is thus pressed against all the levers 12 in a row to withdraw them from the window c. The simultaneous or consecutive advance, of the levers 12 of one row towards the window depends on whether this is effected by the parallel edge 3 or the helical edge 4, and this is dependent on the direction in which the shaft d rotates. Each shaft d has at one end a crank pin i engaged by a slot k in a plate m vertically reciprocated by a cam s rotated by a motor r. The shape of the slits k determines the sequence and manner of operation of the rows of levers 12. The letters 16 mounted on the levers 12, or on a flexible band pressed forward by a cam, or sliding on bars, may be retracted by springs. The rods 10 with vertical bars 9 form a frame which may be removed bodily from the tank through the lid e. The letters &c. are of a thickness greater than the distance visible through the liquid. The Provisional Specification describes a form in which the letters &c. are arranged between rods mounted on a pair of endless chains actuated by liquid-pressed pistons.

Patent GB-820435-A (GB)
Title: Improvements relating to processes for the recovery of cyclohexanol and cyclohexanone
Filed: 1957-10-21
Abstract: The invention comprises a process for the recovery of cyclohexanol and cyclohexanone from the reaction mixture obtained when cyclohexane is oxidized with oxygen, in which the reaction p  mixture is extracted in a first stage with a solvent which dissolves cyclohexanone and cyclohexanol but not cyclohexane, and in a second stage the solution containing cyclohexanol and cyclohexanone is extracted with a further solvent which also dissolves cyclohexanone and cyclohexanol but not cyclohexane, and is immiscible with the first solvent, whereupon the mixture of cyclohexanol and cyclohexanone is removed from the second solvent by distillation. Prior to carrying out these extractions it is preferable to submit the reaction mixture to alkali extraction; the acids so obtained may then be removed by acidification or by means of ion exchangers. Examples of solvents which may be used in the first stage extraction are aqueous solutions of alkyl ammonium salts, and ammonium and alkali metal salts of alkyl-aryl and aryl sulphonic acids such as the sodium salt of toluene sulphonic acid or xylene sulphonic acid or the ethanolamine salt. The second extraction is preferably carried out with solvents having a higher boiling point than the cyclohexanol or cyclohexanone mixture, e.g. esters of phthalic acid, or the esters which are obtained by the oxidation of cyclohexane, and the extraction is preferably carried out with the counter flow principle. Any esters or unchanged cyclohexane which remain after the cyclohexanol and cyclohexanone have been recovered by the distillation of the second solvent may be returned to the oxidation process, or separated by treating with e.g. 80% solution of sulphuric acid.  Alkaline saponification may be carried out after the extraction, followed by acidification in order to obtain more cyclohexanol.  Any water present in the initial reaction mixture must be removed prior to the extraction process.  Examples are given, in which the solvent used in the second extraction is dibutylphthalate and tricresylphosphate.
