Title: Apparatus for checking the user of card in card-actuated machines
IPC: G06Q20/40
Filed: 1975-02-27
Abstract: 1457397 User verification OMRON TATEISI ELECTRONICS CO 27 Feb 1975 [7 March 1974] 8274/75 Heading G4H A system for checking the user of a card having recorded thereon coded information including at least a first and a second code, comprises : means for reading the codes; means for receiving at least the first code read by the reading means to produce a third code; means operated by the user to enter a card owner code; means for receiving at least the second and third codes and the card owner code to check correspondence between the codes; and means for changing the first and second codes. In a first embodiment, the card carries the number n of times the card will have been used just after the next use, and an auxiliary card number equal to a card owner number minus the sum of the squares of the integers from 1 to n. The use number n is used to obtain (n+ 1), its square, and the sum of squares mentioned, by addressing a stored table or using function generators. The sum of squares is added to the auxiliary card number and the result is compared with the card owner number entered on a keyboard, cash being dispensed (or &c.) on equality provided a check using a bank number, account number and balance of account information also read from the card and the requested amount entered on the keyboard is satisfactory. The square of (n+1) is subtracted from the auxiliary card number, the result and (n+1) being recorded on the card as the new values of the auxiliary card number and the use number. On the other hand, if the comparison or check is not satisfactory, the card is returned to the user. A second embodiment uses a sum of random numbers in place of the sum of squares, and the use number is stored on the card in alphabetic form with conversion to and from a number for use in the system. Excess use can be prevented using the use number. Date or time can be used instead of the use number.

Title: Process for extracting gallium oxide from aluminous substances
IPC: C22B58/00
Filed: 1947-03-27
Abstract: Materials containing gallium and aluminium are dissolved in caustic soda and the greater part of the alumina precipitated therefrom.  The remaining solution is treated with an acid, preferably carbon dioxide to precipitate the remainder of the alumina which is much enriched in gallium oxide.  The starting material is preferably recycled aluminate liquors from the Bayer process of obtaining alumina from bauxite or from the anode of aluminium refining cells.  The gallium oxide-containing alumina may be redissolved in caustic soda and the process repeated.  The product may be further enriched by treatment with an acid which dissolves out more alumina and may finally be treated to produce pure gallium oxide by known methods, e.g. by dissolving in hydrochloric acid and extraction from the solution by ether.

Abstract: 589,776. Delivering newspapers &c. in counted batches. IGRANIC ELECTRIC CO., Ltd., and RAPLEY, H. H. April 4, 1945, No. 8300. [Class 100 (i)] In a conveyer for carrying newspapers or the like in a continuous overlapping stream, the newspapers are separated into batches by a stop device which is normally held clear of the stream and is periodically moved to a position where it engages the front edge of one of the papers and thereby checks the movement of this pamper. The device comprises two arms 3 pivoted to a shaft 4 and provided with shoulders 5 which in the lowered position of the arms engage one of the copies and checks its movement on the conveyer 1 without tilting it. The arms 3 are operated by links 7 pivoted to levers 8 mounted on a shaft 9 and carrying a roller 14 engaging a rotary cam 15. The downward movement of the arms 3 is limited by the engagement of a pin 18 on an arm 17 fixed to the levers 8 with a stop 19 pivoted about the shaft 9 and adjusted by rotation of an eccentric 22 connected thereto by a link 21. The drive of the cam-shaft 16 from a shaft 32 can either be through gearwheels 33, 36, 30 or through gearwheels 34, 37, 31 so as to vary the count, the gearwheels 36, 37 being carried by a bracket 35 pivoted on the shaft 32 and adjusted by an arm 41 to bring either the wheel 36 or the wheel 37 into mesh with the corresponding gear on the cylinder. To prevent the copy preceding the count copy from being drawn back with the count copy, it is engaged as the arms 3 drop by rollers 25 carried by spring-pressed levers 26 pivoted to the arms 3. The levers 26 serve also to remove the count copy from the notches 5 as the arms 3 are raised. If the cam 15 is replaced by one with a longer depression, a gap will be formed between the batches on the conveyer.

Title: Improvements in or relating to pneumatic gauges
IPC: G01B13/02
Filed: 1960-03-14
Abstract: 903,120. Pneumatic gauges. ZAUSZNICA, A. March 14, 1960 [March 19, 1959], No. 8864/60. Class 106 (2). [Also in Group XXIX] A pneumatic gauge comprises two separate conduit systems connected to a common supply of air under pressure and each provided with one of two valves 5, 10 (see Group XXIX), which allow regulated escapes of air to atmosphere, and a gauge tube 6 responsive to differences in the two systems, the valve 10 being a measuring valve and the arrangement being such that the gauge provides an indication related to a dimension of a workpiece as the latter is gauged, the measuring valve comprising a body 18 with a bore communicating with an inlet 16 and provided with an air outlet opening 22, and a piston 24 axially slidable in the bore and connected to a sensing member 26 which engages a workpiece 12 being gauged, the piston assuming a position partly to obturate the outlet 22 and so regulate the escape of air in dependence upon the relevant dimension of the workpiece. The air is directed from a distributing chamber 3 to the upper end of the gauge tube 6 and to atmosphere via the throttle valve 5, and the valve 10. A branch from the line leading to the valve 10 leads to one side of a diaphragm 9 in a housing 8, the other side of the diaphragm being in communication with a column of liquid in the gauge 2. In operation, when the workpiece 12 is moved under the plunger 26 connected to the piston 24, the piston is raised thereby throttling the flow of air through the outlet 22 and thus causes an increase in the pressure which acts on the diaphragm 9 and lifts the column of liquid in the gauge tube 6; a zero-graduation 13 is provided on the gauge tube. In order to vary the operating characteristics of the valve 10, i.e. to vary the travel of the plunger 26 in relation to the lift of the column of liquid, a bore 21 in a nozzle 20 of the valve may be varied and/or the shape of the outlet opening 22.

Title: Improvements relating to grinding wheel truing devices for grinding or abrading machines
IPC: B24B53/08
Filed: 1937-03-31
Abstract: 489,519. Trueing grinding wheels. CHURCHILL MACHINE TOOL CO., Ltd., and ASBRIDGE, H. H. March 31, 1937, No. 9126. [Class 60] A profiled grinding-wheel d is trued by a diamond tool o carried by a bracket n which is pivoted about a vertical axis in a carriage m slidable, longitudinally of the machine, on a bracket k which is adjustable, transversely of the machine, on a carriage h which is slidable transversely of the machine, in one direction by a hydraulic plunger i and in the other by a spring w, on a member f which is adjustable, longitudinally of the machine, on the work table a, which latter slides on the machine bed to carry the work piece e, such as a ball race, up to the wheel d. A pinion p on the bracket n, coaxial with the pivotal axis of the latter, meshes with a rack q on the bracket k, and the carriage m is urged towards an abutment s on the grinding head by a spring r. In operation, as the table a approaches the wheel-trueing position, the carriage h is moved forward by the plunger i to engage a micrometer stop u on the member f, and the carriage m is arrested by the abutment s. The continued movement of the bracket k with the table a produces, through the rack- and-pinion gear, a turning of the bracket n. When trueing is completed, the carriage h is moved rearwards, thus also disengaging the carriage m from the abutment s. As shown in Figs. 1 and 2, the tool o is carried rigidly by the bracket n, and thus trues the wheel d to a circular profile. As shown in Figs. 4 and 5, however, the tool o is mounted in a holder n<2> which is pivoted about a horizontal pin 2 in the bracket n and which is urged by a spring 3 against a former 5 secured on the carriage m. Thus the tool o receives from the former 5 an additional movement towards or away from the wheel d so as to true the latter to a profile other than circular. According to the Provisional Specification, the tool o may be slidable against spring pressure in the bracket n and engage at its rear end with a former. Specification 424,261 is referred to.
