Abstract

515,183. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. May 26, 1938, No. 15810. Convention date, May 27, 1937. [Class 106 (i)] [Also in Groups VIII and XXXV] The data-representing positions on a record card for use in statistical machines, include magnetisable material and the actual representations are formed by locally magnetising this magnetisable material. The card may be of any type but. is illustrated as the Hollerith type. Instead of holes .the card includes a continuous sheet of metal Fig, 4 or an individual metallic spot at each data-representing position, Fig. 8 (not shown). One or both surfaces are provided with a covering receptive to visible recording e.g. printed characters corresponding to the.data locally magnetised on to the card. In Fig. 4, an iron wafer or foil 14 is cemented by glue 15 and 17, between a base 13, which may be of paper stock prepared from coniferous chemical pulp free from ground wood, and a layer of paper 16. In Fig. 5 paper 18 is impregnated with granular magnetic material, such .as iron filings 19, and covered with ink-retaining varnish 20. In another form, Fig. 6 (not shown), an.impregnated sheet has glued to each surface a layer of paper; In another construction, Fig. 7 (not shown), a layer of paper has a metallic coating over which is glued a second layer of paper. Colloidal iron may ' be sprayed to give the metallic coating. The coating may also be deposited electrolytically. Each spot on the card D, Fig. 1B, which is to represent data is locally magnetised by a recording magnet B giving a constant excitation field. The card is read by magnets C, Fig. 2 (not shown), in the input circuits of amplifying (thermionic) devices leading to link circuits. The impulses thus produced are used to control tabulating or sorting. machines of known form. To re-use a card it is subjected to an obliterating magnet A, Fig. 1 (not shown), fed with A.C. so that the alternating magnetic field destroys any local remanent magnetism in the card. New data may then be locally magnetised in the card. Specifications 288,327, [Class 106 (i)], and 464,682, are referred to.
