Title: Banking machine
IPC: G07G1/12
Filed: 1973-03-26
Abstract: 1407660 Automated banking system DOCUTEL CORP 26 March 1973 [12 April 1972] 14454/73 Heading G4H In an automated banking system, a customer presents his encoded banking card to a machine, which reads the card data and makes various checks concerning the card and the account(s) it represents, and if neither is found defective the machine allows the customer to select either withdrawal, deposit or transfer facilities and the cash amount concerned. Account(s) data magnetically encoded on the card is read and verified using the system's computer. A number read from the card is compared with the customer's personal identification number, which is entered via a keyboard. Checks are also made to ensure that the card has not expired and has not been used more than a first pre-determined number of times on that day and a second predetermined number of times during the card's valid period. A bank code read from the card is checked to ensure that it corresponds either to the home bank or to one of a number of other banks, which together with the home bank are included within the system. If, as a result of all these checks, it is found that the customer is (under the rules of the system) entitled to only withdrawal facilities, the programme moves to a withdrawal routine. Otherwise, i.e. if full banking facilities are offered, the type(s) of account (credit card account, savings account, cheque account) is determined from the card and up-dated features of such account(s), held in computer memory, are checked. Moreover, in the case of credit card or cheque accounts, a check is made to ensure that the account does not figure on a "bad accounts list". The transaction required is selected via a keyboard. A check is made to ensure that the checks already made entitle the customer to the transaction selected. The cash amount for withdrawal, deposit or transfer from one of the customer's accounts to another is then entered. For withdrawal, currency is dispensed and the banking card data is up-dated. For a deposit, the customer inserts a filled prepared deposit envelope into the machine, which marks the envelope with the current transaction number and stacks the envelope in sequence with others. For a transfer, the customer enters the two account numbers concerned as well as the cash amount. For each transaction a receipt is printed in duplicate, one copy being delivered to the customer and the other retained. The banking card is normally returned to the customer. If certain "error" conditions have been detected, the card is captured. At the end of each transaction, checks are made to ensure that each part of the system is conditioned ready for a new transaction. If a part is not or if, during the course of transaction, "error" conditions are detected, the system goes into a shutdown routine. The system then remains shut down until reset.  Instructions/information are given to the customer via a window display. The various routines of the system programme are described in detail with the aid of flow diagrams.

Title: Improvements in abrasive articles
IPC: B24D11/00
Filed: 1935-05-18
Abstract: 456,985. Grinding tools. TENNANT, W. J., 111, Hatton Garden, London.-(Carborundum Co.; Niagara Falls, New York, U.S.A.) May 18, 1935, No. 14614. [Class 60] Abrasive tools comprise a number of separate bonded abrasive elements individually attached to the surface of a layer of yieldable material, thin in comparison with the abrasive elements and secured to a flexible backing. In the production of abrasive bands or belts, the backing 1, which may be of paper, fabric, leather thin metal, &c., is first coated with a priming coat of adhesive, which may comprise rubber and sulphur dispersed in benzol, &c., or a colloidal dispersion of an isomer of rubber, and a layer 2 of soft, unvulcanized rubber 2 is then applied, and coated with the adhesive. The abrasive coating 3 is then applied and the article cured or vulcanized ; if the abrasive is applied in an unbroken form, it is cut before or after vulcanization or may be broken by flexing so as to obtain small independent elements. Alternatively the abrasive elements may be in the form of separately moulded pieces 5 and this construction may be applied to the manufacture of abrasive discs. Fig. 7 shows a yieldable polishing wheel wherein the abrasive elements either applied as separate elements or fractured as described above, are mounted by the yieldable layer 2 on a backing 1, which is secured to a fabric body 11 ; or the backing may be in the form of an endless belt mounted on a drum with or without a resilient layer, for example, of soft rubber, between the drum and the backing. In another construction of an abrasive disc, a metal disc has attached thereto on one face, by a yieldable cement, abrasive elements separated by gaps running obliquely to radii of the disc. Instead of the use of rubber as the yieldable layer, polyhydric alcohol polybasic acid condensation products or modified vinyl resins may be used. British Specifications 225,436, [Class 60], 351,082, [Group IV], and 397,160, and U.S.A. Specification 1,896,946 are referred to.

Abstract: 131,754. Koster, G. M. A. Sept. 12, 1918. Foot cycles or scooters having a platform suspended between, and below, the axles of a steering and a driving wheel, are provided with treadle driving-mechanism comprising a two-armed lever H, H<1>, which is pivoted to the platform A and provided at one end with a treadle J and at the other end with a toothed arc K<1> engaging with the outer or rear side of a pinion L on the driving-wheel. The pinion is fitted with a oneway clutch and the plane of engagement of the arc and the pinion is different from but parallel to the plane of the foot-lever. To prevent relative lateral displacement between the arc and the pinion, the side member F of the fork of the platform may be extended and provided with a projection M to engage with a channel or slot N in the toothed arc, the channel being closed at each end and furnished with wood, rubber, or other buffers to act as stops limiting the movement of the arc. The channel may, however, be dispensed with, and the stops may be arranged on the sector arms K. A spring Q disposed between a hole, hook, notch, or lug R in or on the arm H<1> of the lever and a hole, hook, lug, or notch Q<1> in or on the member F tends to hold the lever arm H in its highest position. In order to accommodate a large rear wheel, instead of mounting the side members F on a single near transverse belt passing through the bracket I, two short rear bolts may be used and the foot-board gapped to take the front of the wheel. The mechanism is applicable to the forms of scooter described in Specification 127,101.

Title: Improvements in or relating to continuous polymerization processes and resulting products
IPC: C08F2/06
Filed: 1951-06-22
Abstract: In polymerizing unsaturated organic compounds the monomer, a catalyst, and an inert hydrocarbon liquid which is a solvent for the monomer, but a non-solvent and non-swelling medium for the polymers, are continuously added to a slurry of a polymeric material obtained by polymerizing the monomer in the same hydrocarbon liquid, while maintaining the temperature of the slurry between 40 DEG  and 150 DEG C., and continuously removing a minor portion of the slurry.  Styrene and maleic anhydride copolymers are exemplified but vinyl acetate, vinyl ethers, di-vinyl benzene, p-chloro styrene, p-methyl styrene, or gaseous vinyl chloride (under pressure) may wholly or partially replace the styrene, and itaconic, citraconic, acrylic or methacrylic anhydrides or the alkyl half esters of maleic acid, may replace the maleic anhydride.  Terpolymers of styrene or vinyl acetate with maleic anhydride and acrylic or methacrylic acid, or acrylonitrile may be prepared.  Acrylic and methacrylic acids, acrylamide, acrylonitrile and other unsaturated compounds containing carbonyl, carboxylic anhydride, amide and nitrile groups may also be polymerized.  The inert hydrocarbon liquid includes their chlorinated derivatives and examples are benzene, toluene, xylene, chlorobenzene, dichlorobenzene, chlorotoluene, heptane, hexane, octane and nonane, cyclo-hexane and pentane, ethylene dichloride and carbon tetrachloride.  The catalysts may be selected from diamyl sulphide, ditertiary dodecyl disulphide, a , a 1-azobis isobutyl nitrile, ditertiary-butyl perbenzoate or peroxide, ditertiary-amyl peroxide, diethyl peroxide, lauroyl and benzoyl peroxides and t-butyl and cumene hydroperoxides.  Cross-linking and chain transfer agents such as maleic or fumaric esters of polyhydric alcohols, diisopropenyl or divinyl benzene, dodecyl mercaptan and carbon tetrachloride may be present.  The initial polymer slurry may be prepared by a batch process and additional quantities of monomer, hydrocarbon liquid and catalyst are then added continuously, preferably under reflux conditions and at an equivalent rate to that at which the slurry is removed.  The polymer is separated by filtration or by centrifuging and treated with hot air and steam.  The product is in the form of free-flowing particles of 8 to 80 microns diameter and of apparent density between 28 and 40 lbs. per cubic foot. Examples describe the copolymerization of styrene and maleic anhydride, alone or with methyl acid maleate, divinyl benzene and acrylic acid.  Organic solvent solutions of the product may be used to coat fabrics, metal or wood and aqueous solutions of the alkali metal or ammonium salts used to size nylon yarn. Specification 459,947 is referred to.

Abstract: 589,593. Radiolocation. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Nov. 20, 1941, No. 14941. Convention date, March 8, 1940. [Class 40 (v)] In a pulse radiolocation system in which one or more oscilloscopes is employed to indicate the angular co-ordinates of an object, undesired signals are eliminated by causing the blackout on the cathode-ray oscilloscope to be removed by rectangular repetition frequency pulses of duration slightly greater than the duration of the reflected signals and of which the phase is adjustable relative to the signals under the control of a cursor in front of the rangeindicating oscilloscope. The angular coordinates of objects may be indicated by the maxima or minima of signals displayed as deflections of linear traces on oscilloscopes scanned in synchronism with the movement of the directive aerial, system, the scanning voltages preferably being obtained from resistance generators coupled to the moving systems. The Specification as open to inspection. under Sect. 91 also states that the difficulty of observing a maximum may be removed by differentiation of the applied signals. The phase of the signal selecting pulse S, which may be produced by a blocking oscillator, is controlled by the cursor C which is moved to follow the variations in range D of a desired reflection signal M displayed on the rangeindicating oscilloscope. The pulse S which overlaps the signal M when the cursor is correctly aligned, is fed to the grids of the angular co-ordinate oscilloscopes to permit only the selected signal M to be visible thereon. A transmitter A also controlled by the cursor C may be employed to provide a remote indication of the range D. This subject-matter does not appear in the Specification as accepted.

Abstract: 604,449. Typewriters &c. RANDALL, J. W., and DICKINSON & CO., Ltd., J. June 14, 1945, No. 15097. [Class 100(iv)] Duplicating arrangements.-In a typewriter or like machine wherein relatively continuous paper webs are interleaved with a set of carbon sheets for duplicating copies, an attachment therefor is provided comprising a supporting-frame 1 having yielding catches 5 which in their normal position are engaged by the carbon-sheet holder 25 to prevent forward movement of the sheets when the webs are being fed forward for severing the typed copies. The catches 5 are pivotally mounted on blocks 6 adjustable lengthwise of the frame 1 according to the length of the carbons, the catches being held in their normal positions by weights 7 or springs which can be adjusted to vary the resistance to tilting of the catches. The weights can be replaced by a bar joining the two catches situated at either side of the frame 1. Stops 31 on the blocks 6 limit the rearward movement of the holder 25. In use, after the sheets have been typed, the webs and carbons are fed backwardly until the holder 25 tilts the catches 5 which rise behind it, the carbons now being free from the platen 23 and feed rollers 22. The catches retain the carbons while the webs are being fed forward to detach the typed copies. The carbons are now interleaved with the succeeding sections of the webs and by applying finger pressure, are drawn forward by the webs when the rollers 22, 23 are operated, tilting the catches 5 against the action of the weights 7. The frame 1 is secured to the paper rest 21 by clamps 11 which may be adjustable transversely of the frame. In addition, a strut 20 engaging a part of the machine may be provided. Paper supports.-Adjustable side guides may comprise discs on a roller 3 mounted on a spindle 2 attached to the frame 1 or members 4 looped over the roller 3 and mounted on the edge of the frame 1. A central ridge on the frame 1 curves the papers to make them more rigid as they are fed rearwardly. Indicators.-A pointer 10 may be adjustably mounted on the edge of the frame to indicate when the webs have been fed forward the correct amount. Specification 604,450 is referred to.
