Title: Circuit component
IPC: G11C11/44
Filed: 1963-12-31
Abstract: 1,076,194. Superconductor devices. FORD MOTOR CO. Dec. 31, 1963 [Dec. 31, 1962], No. 51420/63. Heading H1K.  A persistent current is established in a superconductive thin film ring, characterized by a critical electron velocity (i.e. the greatest electron velocity at which the film is superconducting) which represents a current less than that necessary to produce the critical magnetic field, by applying to the ring a magnetic field substantially greater in intensity than that required to induce the critical electron velocity therein and then decreasing the applied magnetic field to decrease the electron velocity to a value algebraically less than the critical electron velocity and establish a persistent current in the superconductive film. As shown, Fig. 4, a computer memory element 10 comprises a glass or quartz rod 11 having a thin superconductive film 12 plated round its circumference. A pulsing coil 13 produces a magnetic field at least twice that required to induce a current having a critical electron velocity in the superconductive film 12. This causes a current of the critical electron velocity, but no larger, to flow in the film 12 which remains superconductive, leaving some uncancelled magnetic flux which penetrates the superconductive film 12. The applied magnetic field is then reduced and the induced current decreases accordingly until, when the field has been reduced to zero, a current of the critical electron velocity but flowing in the opposite direction remains stored in the element. The stored information is read out by applying a pulse to the coil 13, the nature and time of the consequent change in the magnetic field being dependent upon the size and direction of the stored current. This change in the magnetic field is detected by means of a sensing coil 15 connected to an amplifier 16. A modified element, Fig. 5, employs three coaxial superconductive films 22, 24, 26, different magnetic field intensities being required to induce currents in (and read out from) the different films.

A document reader 2 is connected to a computer 1 through a switching device 3 which passes data to the computer immediately it has been read over an input/output channel, and causes the computer to issue a control word SW for the nth document after the (n + 1)th document has been read. The control word directs the corresponding document to one of a number of sorting receptacles or it may control a printer. A character register 5 produces a pulse zd for each character read, and in response thereto, device 3 produces character gating signals tzi to transfer the data to the computer via gates S1, S4. Similarly, when register 6 issues a signal bez signifying the end of a document, device 3 opens gate S2 to transfer an end of document character to the computer 1, this character including debit/credit and checking information. A series of document detectors 8 is arranged downstream of reader 2, these controlling the entry of the sort control word into that one of registers E1-E4 which corresponds to the position of the document when the control word SW is issued in response to the end of document character for the following document. The control word SW also includes a feed instruction BA for a free-running document feeder 4, 14. If a document reaches the first detector 8 without any following document being read, a simulated end of document character is generated from line pb. A control 9 can generate a stop signal in the event of a machine malfunction and this is signalled to the computer over gate S3. A stop withdrawal command to unit 4 may be issued over BA from the computer.
