Title: Data reading system
IPC: G06Q20/34
Filed: 1976-06-02
Abstract: 1520594 Security card NCR CORP 2 June 1976 [20 June 1975] 22760/76 Heading B6A [Also in Division G4] A data reading system has a record medium such as a credit or identity card carrying diffraction gratings 12 forming first machine readable data and carrying machine readable data in a form other than diffraction gratings and a reader which in operation compares the first and second data and produces a signal indicating whether a predetermined relationship exists. The diffraction gratings are embossed on a strip using an embossing head (Fig. 4, not shown) carrying parallel lines. The embossing head is rotated so that the lines lie at one of a preselected set of angles to the longitudinal axis of the strip and an area of the strip is embossed. The strip is then advanced and a further area is embossed. The strip has a control grating at each end and alternating space and data gratings. The strip is situated on a body portion 18 of the card and is covered on both sides by a layer 20 of transparent plastics material which is sealed to the body portion. The body portion 18 can carry printing on either side. The second data is preferably recorded on a magnetic strip which may be located on the transparent layer on either side of the card. A reader for the card has a light proof housing 88 having a slot 90 allowing passage of the card. The housing has supports 92, 94 with guiding slots 96, 98 for the card. The card is driven by wheel 102. An opaque support 106 has a pin hole 108 allowing light from a light emitting diode 110 to pass. The light passes through   collimating lens 114 to a diffraction grating on the card. The diffraction grating produces two first order diffracted rays at equal angles on opposite sides of the reflected ray. The diffracted rays pass through the collimating lens and are detected by photodetectors 118, 120, 122, 124, 126 mounted on support 106. The second data on the card which is preferably on the reverse face to the gratings is read by a conventional magnetic reader 128. Data from the gratings and the stripe are compared to produce a validity signal if predetermined criteria are valid. The card may control a cash dispenser or a gate or door.

Title: Method and apparatus for the electrolytic treatment of metals
IPC: B23H3/04
Filed: 1929-07-24
Abstract: 335,003. Gusseff, W. July 24, 1929. Metals, removing; electrolytes, circulating; supporting electrodes.-Apertures or cavities are formed in metal bodies by local electrolytic solution of the metal while connected as anode; metals may be cut by step-by-step formation of narrow apertures. The apparatus shown in Fig. 1 comprises a tube 3 of non-corrodible metal connected as cathode provided with insulating feet m and an insulating covering 1. Electrolyte is supplied through the tube 3 and withdrawn through the annular space surrounding it. In the modification shown in Fig. 12, the cathode 3 is mounted in a member A so as to be surrounded by and spaced from an insulating tube 1. Electrolyte is supplied by a pipe 25 through the cathode 3 and withdrawn through the space between the cathode and tube 1 leaving the member A by a pipe 19 ; it passes to a tank provided with filtering means and is returned to the apparatus by a pump. The circulation is maintained until the electrolyte has a predetermined content of the metallic salt. The end of the tube 1 abutting on the work passes through a packing-ring 2 pressed down by an implement 13. As the cavity 4 extends the tube 1 and the cathode are pushed through the packing ring. The member A is provided with a two-part ring 26 acting as cathode connection and a cap 22 connected to an insulated handle. The cross-section of the aperture formed is the same as that of the tube 1. The various parts of the member A are provided with screwed connections to facilitate removal and replacement of the cathode. The cross-section of the cathode should be the same as that of the tube but for cavities of triangular or polygonal section, the angles of the cathode section should be more accentuated than those of the cavity. By use of a cathode disposed between two insulating tubes an annular cavity may be made; by extending this completely through the metal a large aperture may be made, the core falling out on completion of the operation. A metal plate may be cut continuously by means of a cathode enclosed in a flat insulating tube provided with a cut on one of the narrow sides. The tube is inserted through an aperture in the metal and packing rings are mounted on both sides. The aperture is gradually extended on the side provided with the cut, the tube being moved accordingly. The electrolyte may be a 3-8 per cent solution of hydrochloric acid, the current density 150-300 amps per sq. cm. at 110 volts, and the velocity of the electrolyte 300-600 metres per min.

Title: Process of preparing resinous condensation products having ion sorbing properties and products obtained thereby
IPC: C08G12/12
Filed: 1944-11-21
Abstract: A cation-active synthetic resin is prepared by heating a solution of a synthetic resinous condensate prepared from an aldehyde and an amino compound in presence of a bisulphite according to the process of Specification 595,366 in a solvent which is present during the reaction until a gel is formed, heating the gel at a temperature and for a time sufficient to form an infusible, porous mass and comminuting said mass.  The preferred solvent is water.  Alcohols, e.g. methanol, ketones, e.g. acetone or aqueous mixtures of these may be used.  The heating may take place at 85-135 DEG  C., e.g. 100 DEG C. for a few hours.  If desired, the condensate may be spray-dried and the powder heated to cure it.  The condensation products may be applied to supports such as cloth, asbestos or clay and cured thereon.  The resins may be used intermittently or continuously for exchanging cations in solutions, e.g. by passing the solution through a bed of the resin or by stirring the resin in the solution. Regeneration of spent resin may be effected by treatment with aqueous solutions of salts, e.g. sodium or potassium chloride, followed by washing.  Examples describe the preparation of resins from (1) melamine, aqueous formaldehyde and sodium sulphite, the initial condensate being heated at 105 DEG  C. for 5 hours, comminuted and screened to yield particles of 0.3 to 0.4 mm. diameter with good cation-exchange properties; (2) urea, aqueous formaldehyde and sodium metabisulphite; (3) urea aqueous acetaldehyde and sodium metabisulphite; (4) melamine, urea, aqueous formaldehyde and sodium sulphite.ALSO:A synthetic resin prepared by heating a solution of a condensation product of an aldehyde, an amino compound and a bisulphite (see Group IV) in a solvent, preferably water, until a gel is formed, heating the gel to form an infusible porous mass and comminuting said mass, is used for absorbing cations such as magnesium, zinc, calcium, iron, manganese and lead from solutions. The ion exchange may be effected by passing the cation containing fluid through a bed of synthetic resin of suitable particle size or a batch of the synthetic resin may be stirred in the cation-containing liquid.  Revivification of spent resin may be accomplished by treatment with a liquid containing desired cations, e.g. aqueous solutions of sodium or potassium chloride followed by washing with soft water.  The resins may be used over a wide range of pH and do not impart colour to the treated liquids.
