Title: Improvements relating to electrical apparatus for adding numbers and registering thetotal
Inventor: SPENCER ROLF EDMUND
IPC: G06F7/50
Filed: 1950-03-23
Abstract: 693,909. Digital electric calculating apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 14, 1951 [March 23, 1950], No. 7266/50. Class 106 (i). Apparatus for adding numbers and registering the total in a scale of radix M comprises n trigger devices, each having two states of equilibrium between which they alternate on the application of triggering pulses, means coupling the devices in cascade to produce a series counter chain having 2<SP>n</SP> states, 2<SP>n</SP>>M and the values 0 to M-1 being assigned to M states of the chain, means for applying triggering pulses individually to the devices in the chain so that the addition of numbers equal to or greater than unity can be represented, the coupling means being so arranged that on the application of pulses representing a number less than M the chain initially changes to the correspondingly higher one of the 2<SP>n</SP> states, and means so arranged that when the initial changes produce a state other than that whose assigned value represents the resultant total a further change is produced to the last-mentioned state. A quinary adder is described which may follow a binary stage so as to provide a decade unit. The entry points 13, 14 and 15 are for the digits 20, 2<SP>1</SP> and 2<SP>2</SP>, respectively, but the highest digit which will be entered this way is 2<SP>2</SP> or 001. For additions giving a total not greater than 4 the adder operates as a normal binary chain, but when the total is 5 (101), 6 (011) or 7 (111) a gate 22 operates to feed a pulse in parallel to the inputs 13 and 14 (equivalent to adding in 3 (110)), and so carry the counter through the " forbidden " states. This operation is effected by a gate 21 which feeds out a pulse if a pulse appears on either connection 19 or 20 or both, and the gate 22 of threshold two. When the total is 8 (000 and carry) the correcting pulses on inputs 13 and 14 are derived from the carry pulse via a line 23. An inhibitor connection through a delay device 25 to a gate 24 of threshold one, prevents feed-back through line 23 to the first two stages when the carry is a direct result of the stimulation of gate 22. An alternative inhibitor connection 26 is shown dotted. Other arrangements providing for the corrective feed-back are also described.

Title: Improvements in and relating to colour forming developers and process of colour development
IPC: G03C7/333
Filed: 1939-03-09
Abstract: 527,493. Photographic colour development. KODAK, Ltd. (Eastman Kodak Co.). March 9, 1939, Nos. 7639/39 and 1015/40. Addition to 503,826. Drawings to Specification. [Class 98 (ii)] [Also in Group IV] In a modification of the invention claimed in Specification 503,826, one or more of the emulsions is developed with an alkaline coupling developer containing in solution a coupling component consisting of a derivative of a dye or lenco dye having an attached but removable group containing a coupling function and the resulting coupled dye is either left as such in the emulsion or decomposed to remove the entire group containing the coupling function so as to leave the original dye. The attached group may contain one or more solubilizing groups, such as sulphonic or carboxylic acid groups. The attached group may be removed by hydrolysis, with oxidation if necessary, to produce the dye. Precipitating agents for the dye or leuco dye may be present. Derivatives of azo, vat. and anthraquinone dyes may be used. The coupling developer may be of the usual aromatic amino type. Examples of suitable compounds are p-azophenylacetoacetanilide, 2-acetylacetaminoanthraquinone and 2-dimethyl amino - meso-salicylanthrone. If the first example is used with the developer p-aminodiethylaniline or the second with the developer 2:6-diiodo-4- aminophenol stable yellow dyes are formed. Anthraquinone derivatives giving different colours, which may be substituted with a cyanacetyl- or cyanacetylamino group in the case of magenta derivatives or with a phenolic group in the case of blue-green derivatives, may be used to give stable dyes. The process may be applied to the formation of coloured images on plates, films or papers carrying differently sensitized mixed grain emulsions or differently sensitized emulsion layers superposed on one or both sides of the support. A sound track may be provided. Specifications 440,032, 440,089, 503,827 and 512,559 also are referred to. p-Azophenylacetoacetanilide is prepared by the condensation of p-aminoazobenzene and ethyl acetoacetate. 2-Acetylacetaminoanthraquinone is prepared similarly from 2-aminoanthraquinone. 2-Dimethylamino-meso-salicylanthrone is prepared by reducing 2-dimethylaminoanthraquinone and condensing with salicylic aldehyde.

Filed: 1962-02-27
Abstract: 931,274. Work-feeding arrangements. LEIPZIGER BUCHBINDEREIMASCHINENWERKE VEB. Feb. 27, 1962, No. 7697/62. Class 31 (1). [Also in Groups XXII and XXXVIII] A method of controlling adjustable machine parts, e.g. slides or carriages, comprises storing measurement information, coded as coarse, medium and fine measurements, and effecting a relative displacement, corresponding to the fine measurement values stored, between a medium measurement pulse transmitter and a pulse reader. The measurement information is stored on a magnetic tape, punched tape or a punched card A, Fig. 1, in the form of coarse, medium, and fine measurements. The latter values are fed into fine measurements stores B1, B2 which via a displacing mechanism C bring about displacement of the reading element in a medium measurement pulse transmitter D until the position of the reader corresponds to the stored fine measurement values. Machine carriage E is switched on by store B2, and a coarse measurement pulse transmitter F supplies a pulse to a store G after each coarse measurement unit moved through by the carriage. When the value in store G equals the value in store A transmitter D transmits to medium pulse store H until this value equals the value in store A. Upon the penultimate pulse, carriage E is slowed down via a change-over device J and is then stopped on the final pulse. The carriage displacement mechanism comprises a spring-urged tape spool 2, Fig. 2, a magnetic tape 3, a magnetic head 4, adjustably secured to machine frame 1, and a cam 10 for adjusting the tape relative to the head when taking up the fine measurement values. Tape 3 is connected to carriage 9 by a slidable bracket 6 and the latter is moved, when cam 10 is rotated by a pawl 13 actuated by an electromagnet 15. Cam 10 has a lift equal to a medium measurement unit and the rotation produced by each ratchet tooth 12 equals a fine measurement unit. Carriage 9 is moved mechanically and is brought to a standstill in accordance with stored positions on tape 3 but only the medium and coarse pulses are counted, as the fine measurement values are added to the former by relative movement between tape 3 and head 4 produced by fine measurement pulses supplied to electromagnet 15. In a modification, head 4 may be displaced by cam 10 with tape 3 secured to carriage 9. In a further modification, the step-by-step motion of cam 10 may be provided by a motor driven in conjunction with motor selectors.
