Title: Improvements in or relating to information storage apparatus and methods of making record mediums
IPC: G06K7/06
Filed: 1961-03-27
Abstract: 922,256. Statistical record members. M. MONDSCHEIN. March 27, 1961, No. 11159/61. Class 106 (1). A record card or tape has a number of conductive areas arranged in pairs and connected by a conductive link of low current carrying capacity which may be destroyed by application of a recording current to record data. In the form of Fig. 1 a record strip 20 has five conductive tracks; 22A, 22B, 22C, 22D being data tracks and 22E being a clock track. Each track is engaged by a pair of contacts 16A, 18A to 16E, 18E. As the strip moves the contacts engage successive pairs of wide conductive portions in each track and in the clock track the contacts engage adjacent teeth. The tracks may be of a conductive ink, e.g. silver ink, printed on the paper or of aluminium foil bonded to the paper. The contacts 18A- 18D are connected to earth and contacts 16A- 16D are connected via ganged two-position switches 30 to switches 37A-37D or to relays 40A-40D. To make a recording, the switches 30 are in the position shown connecting the switches 37A-37D to the contacts 16A-16D. A source of current 50 is connected through the contacts 16E, 18E of the clock track to the other side of the switches 37A-37D. This ensures that current is applied only when the tracks are properly indexed with the contacts. If a switch, say 37C is closed the current passing between contacts 16C and 18C fuses the narrow link of conductive material between the wide areas 24C and 26C. This open-circuit stores one data bit and it is detected by moving switch 30 to the sensing position so that the relays 40A-40D are connected to the contacts 16A-16D. The source 50 is connected to the other sides of the relays 40A-40D through contacts 16E, 18E and resistances 44A-44D so that all relays operate except relay 40C associated with the fused link. In the form of Fig. 2 the contacts are in the form of rollers co-operating with two independent tracks, each having wide areas 64A, 66A in the form of teeth connected by fusible links 68A. The teeth intermesh. In the form of Fig. 3 the pairs of wide conductive areas are all separate, the connecting links being removed where necessary.

[Also in Division G1] A rotating magnetic drum is associated with a writing head which magnetizes the drum surface with N or S polarity, and an angularly adjustable reading head which senses a change in magnetic polarity to produce an output signal and cause the writing head to change polarity. Thus the number of output signals per revolution depends on the angular relationship between the two heads, and the signal rate is also dependent on the speed of revolution of the drum. As used to control the rate of feed of a lathe in accordance with the rotational speed of a cutting tool (Fig. 2), a first magnetic drum 11 is driven with the headstock 22, and a second magnetic drum 16 is driven by a motor 25 driving the lead screw 24. Each drum has a writing and reading head spaced so that when the headstock speed and the lead screw speed are in the correct ratio, the pulse trains from the two reading heads have the same frequency. Any difference is established at 17 and used to adjust the speed of motor 25.
