Abstract: 1,182,247. Detergent composition. J. J. LORANT. 1 June, 1967 [1 July, 1966], No. 29619/66. Heading C5D. [Also in Division C7] Metal surfaces are cleaned, cleared of corrosion products and prepared for painting by application of a preferably aqueous solution comprising a hydroxy or polyhydroxy carboxylic acid containing one or more carboxyl groups, or a lactone of such an acid, a non-ionic wetting agent selected from alkyl-phenol polyethoxylates and a salt of a sulpho-dibasic fatty acid half ester of a fatty alcohol polyglycol ether. A dry powder containing the above ingredients may be mixed with water when required. Alkali metal phosphates, such as trisodium phosphate and/or sodium tripolyphosphate, may be included in the solution, whose pH may be adjusted and/or controlled by inclusion of a buffer system, such as sodium phosphate and phosphoric acid and which may contain sodium nitrite or nitro-guanidine as an oxidizing accelerator and a soluble salt of a derivative of N- methyl-glycine to reduce "smut", for example the sodium salt of an N-acyl derivative of N- methyl glycine. Preferably the solution contains, as the salt of the dibasic sulpho-acid derivative, the disodium salt of the half ester of sulpho-succinic acid and an aliphatic (e.g. lauryl) alcohol polyglycol ether, and the carboxylic acid or lactone may be selected from malic acid and the gamma and/or delta lactones of gluconic and heptonic acids. The invention may be employed to treat surfaces of ferrous metals, or of aluminium and its alloys, and may be used to degrease the surfaces, clean them of corrosion products and passivate them by immersion in a single bath, or two baths may be employed successively and the first tank replenished from the second, which is maintained at the preferred strength by addition of fresh solution. The optimum concentrations of the components of the composition in the aqueous working solution are:- Main components Glucono-delta-lactone and/ or heptone-delta-lactone (if present) . . . . 10 to 30 g./l. Malic acid (if present) . . 7À5 to 30 g./l. Wetting agent . . . . 2À5 to 10 g./l. Salt of a sulpho-dibase half ester of a fatty alcohol polyglycol ether .. 2À5 to 10 g./l.

Title: Improvements relating to the control of data tape movement
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: G06K19/06
Filed: 1964-07-24
Abstract: 1,062,907. Statistical apparatus. STANDARD TELEPHONES & CABLES Ltd. July 24, 1964, No. 29758/64. Heading G4C and G4M. Each of a series of groups of digits is recorded together with one of a series of regularly repeated characteristics, and on read-out of the digit groups, means is responsive to an interruption or disorder in the regular series of characteristics to indicate a malfunction in the read-out process. The digit groups may be recorded, for example, on paper or magnetic tape, or in a ferrite core store. The Figure shows a tape in which each digit group is punched in tracks 3-7 in 2-out-of-5 code, and alternate digit groups have an additional hole punched in track 8. In reading such a tape, a bi-stable circuit is switched between its two states as successive digit groups are read, and its state is compared with the output of a device sensing track 8, an unequal comparison signifying a read-out error, due for example to one digit group being omitted or read twice. An alternative method of detecting read-out errors is to record alternate odd and even parity bits with successive digit groups, and to check that successive digit groups read from the store have opposite parity.
