Title: Improved method and means for detecting alterations in checks or other documents
IPC: B42D15/00
Filed: 1931-06-30
Abstract: 379,450. Cheques &c. DEHN, F. B., 103, Kingsway, London.-(Sagmeister, J. ; 2570, Madison Road, Hyde Park, Cincinnati, Ohio, U.S.A.) June 30, 1931, No. 18881. [Class 16.] In a method for preventing the fraudulent alteration of cheques, or for the identification of articles or persons by means of perforations applied to the document in a certain arrangement, and adapted to be interpreted by means of a key chart, the position at which the perforations are to be made is determined by means of a locater-frame, which is placed on the chart in a prearranged position. The chart 1, Fig. 1, is ruled into squares, which contain numbers arranged arbitrarily but in such a manner that all of the numbers 0 to 9 occur in any consecutive ten squares taken horizontally. The chart also has co-ordinate markings 3, 4 on two sides, which may consist of the days of the month and the letters of the alphabet. The locaterframe 5, Fig. 2, is of rectangular form, and has its edges divided into numbered sections. The frame 5 is placed on the chart in a position determined, say, by the day of the month and the first letter of the payee's name. The amount of the cheque is read off from the numbers inside the frame, and holes 6, Fig. 3, are punched in corresponding positions in the cheque 7 by means of a punching-machine. The cheque is tested by placing it on the chart in the same position as that occupied by the frame, and observing the numbers visible through the perforations, which should agree with the amount of the cheque. To prevent the possibility of the payee's name being altered, an identification number may be used, determined, for example, by the third letter of the name. The frame is placed on the chart in the new position so indicated, and the numbers occurring within the frame in the same relative positions as the perforations in the cheque, or the sum of those numbers, serves as the identification number.

In a rubber-lined fire hose, the woven textile jacket, e.g. of cotton or flax fibres, of the hose is proofed with a fungicide and carries an elastomeric deposit derived from a latex which is film-forming when dried in air, the deposit consisting substantially of a modified polyvinylidine chloride which has been internally plasticized by copolymerization. The weight of the deposit, which may be a latex of approximately 55 per cent by weight of resin content, is at least 2.5 per cent, but preferably is between 5 and 25 per cent, of the weight of the hose. The latex may be that known as " Geon 652 " (Registered Trade Mark). Preferably, the fungicide is lauryl pentachlorphenol applied in a quantity of 1 per cent of the weight of the hose, or zinc chloride. The latex may be applied to the jacket after proofing of the latter with fungicide and prior to the introduction of the lining into the jacket, the lining preferably being reinforced by a textile carrier and introduced into the jacket by the method described in Specification 538,455; alternatively, the fungicide is mixed with the latex and the jacket is impregnated with the resulting admixture, or the fungicide is applied to the yarn before weaving the jacket. In examples described, the jacket has cotton warps and nylon wefts. To eliminate uneven darkening of the stored, coiled hose when the latex is exposed to light, the latex is pretinted by dispersion in " Vulcafor " Fast Brown B (Registered Trade Mark).

To register the setting, the teeth of the wheels 23 co-operate with perforations 21 in a driving ring 20 rotatable on the corresponding drum 13 ... 16 of the totalizer. Each totalizer drum is freely mounted on a shaft 10 and is formed with ratchet teeth 18 that co-operate with a spring-pawl 28 on the driving ring. Integral with each drum is a disc 19 with pins 38 corresponding in number with the numerals on the drum. The drums may bear two sets of numerals arranged in opposite directions for subtraction as well as addition. Transfer mechanism. In accordance with the invention the transfer mechanism is of the pawl-lever type, but in certain denominations a travelling pawl may be provided as shown for the lower denominations in Figs. 3 and 4. The right-hand drum carries a pivoted pawl 40 that co-operates with a cam 39 secured to the spindle 10 and is pushed outwardly thereby to engage one of the pins 38 on the next higher drum. The transfer arrangement for the higher denominations is shown in Figs. 6 and 7 ; each drum from the shillings drum upwards carries a cam disc 47 which when transfer is to be effected releases a holding detent 51 and permits a spring-controlled pawl 44 to engage a notch 49 in the cam disc and to bring the end of the pawl into engagement with one of the pins 41 on the next higher drum. Further rotation of the cam disc rocks the pawl carrying lever 42 to complete the transfer. The lever 42 is counterbalanced for return to normal position after transfer. In a modified form, the lever is formed as a bell-crank carrying two pawls, one engaging the cam disc and the other the pins on the adjacent wheel. Zeroizing-mechanism. To reset the indicator discs 2 ... 5 each sleeve 6 has secured thereto a pulley 29 to which is attached one end of a wire or cord 30 carrying a weight 31. Each sleeve is also provided with a double flange 32 between which is arranged the bifurcated end of an arm 33 secured to a rod 34. The rod 34 is rocked by pressing in a push-button 35 so as to slide the sleeves 6 forwardly to disengage pins 37 on the pulleys 29 from holes in the discs 25. In the disengaged position the weights 31 are effective to rotate the indicator discs to their zero position.
