Title: Improvements in or relating to data storage devices
IPC: F16T1/16
Filed: 1950-08-09
Abstract: 677,684. Data storage devices. BRITISH TABULATING MACHINE CO., Ltd. Aug. 9, 1950 [Aug. 12, 1949], No. 19800/50. Class 106 (i). A data storage device comprises a plurality of flexible wires rigidly mounted at one end and free at the other to flex in and out of engagement with latches whereby electrical contact is made in a latched position but not in the unlatched position. The apparatus is adapted to receive and store information from punched cards, whereby the data may be entered concurrently or column by column, and read out in either fashion. A plurality of wires 22 are mounted between an insulated block 40, Fig. 4, which has a series of spaced grooves for the purpose, and a bus-bar and clamp 41. At the upper end of the wires an insulating guide-block 48 is fixed to the base-plate 38. The outer face of the block 48 has a guide channel 50 in whihc is mounted for reciprocating movement a storage comb 52. The free edge of the comb is notched to accommodate separately the storage wires 22 so that when the comb 52 is reciprocated the wires will be flexed in a lateral direction in equally-spaced relation to one another. The comb 52 is rocked by movement of the tail 60 of a member pivoted at 58 by actuation of the electromagnet 64 and its associated armature 62. Traversing the storage wires in perpendicular intersecting relation are a plurality of reading bars 24. These have formed thereon projections 30 which are normally spaced a short distance from the storage wires, when the wires are flexed laterally they are in the path of the projections 30, so that on reciprocation of the reading bars, the projections 30 will engage the flexed wires and move them beyond the latch heads. A storage wire in latched position is shown in Fig. 1 at 22a. When wires are latched in stored position representative of either numerical or alphabetic values they are retained for subsequent read-out upon reciprocation of the reading bars which are energized through leads 32 and constitute part of a control circuit which is completed through a reading projection 30 and a latched wire 22a. A resetting magnet 36 which operates a resetting bar 34 is provided to clear the stored data when required. When the reset magnet 36 is energized levers 56 of each of the storage plates will be moved to bring the upwardly-projecting fingers into contact with their respective latchplates 28. Thereafter, as each storage plate magnet is energized the armature 62 will rock lever 56 about its axis, and thereby shift the latch plate 28 to the right as viewed in Fig. 3, thus releasing any wires that may have been latched.

Patent GB-809730-A (GB)
Title: Method of preparing diesters of phthalic acids
IPC: A23L29/212
Filed: 1957-06-25
Abstract: The invention comprises a process for the preparation of phthalic acid diesters by the oxidation, possibly under pressure of a mixture of xylene and an ester of toluic acid with a monovalent saturated aliphatic alcohol containing 1-4 C atoms, the proportions by weight of xylene to the ester being from 1 : 3 to 1 : 1, in the presence of oxygen or gases containing free oxygen, between 80 DEG  and 250 DEG C., in the presence of an oxidation catalyst, and carrying out the reaction for at least 4 hours until the xylene has been completely converted into toluic acid, and then continuing the oxidation until substantially, the same quantity of toluic acid ester has been oxidized as toluic acid has been formed by the oxidation of the xylene, esterifying the resulting oxidation mixture with the monohydric saturated aliphatic alcohol corresponding to the ester group of the toluic acid ester used as starting material, and separating the phthalic acid diester thus formed from the remaining toluic acid ester. The remaining toluic acid ester may be subjected to further oxidation together with fresh xylene.  Among suitable oxidation catalysts are metal compounds which are soluble in the reaction mixture, e.g. cobalt or manganese salts of fatty acids containing 6-12 C atoms, such as first run fatty acids or cobalt hexanate, or cobalt salts of toluic or benzoic acids.  The process may be carried out batchwise or continuously.  In the latter case the oxidation is preferably carried out in several aggregate stages, and the oxidation should be started in a phase containing xylene and then continued in a phase-free from xylene.  Major quantities of unreacted toluic acid esters should be present at the end of the oxidation, to act as solvents or dispersing agents for the oxidation products obtained.  The diesters thus prepared may be separated from the other reaction products by distillation or crystallization.  Dif ferent isomers of xylene or toluic acid esters or mixtures thereof may be used as starting materials. Examples are given of the preparation of dimethyl terephthalate from p-xylene and methyl p-toluate, dimethyl isophthalate from m-xylene and methyl-m-toluate, the three dimethyl phthalate isomers from a commercial xylene mixture and the mixture of toluic acid methyl esters, prepared by the esterification of that mixture.  Methyl benzoate is also formed as a by-product.
