Patent GB-917931-A (GB)
Title: Selecting apparatus, for instance, for selecting portions of stored data
IPC: G11C11/06
Filed: 1959-12-31
Abstract: 917,931. Digital data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 31, 1959 [Dec. 31, 1958], No. 44360/59. Class 106 (1). The storage positions of a magnetic core matrix are sequentially scanned but only the contents of those cores between two marked cores in an axuiliary plane are read out. Cores of the auxiliary plane (Fig. 1) are marked by plugging windings 34 on the cores to a source of current 35 to counteract the effect of coincident current pulses from sources 23, 24 and inhibit an output pulse as the core is scanned. A timing device 38 produces pulses a to d (Fig. 2). Pulse a on line 39 sets a trigger 36 raising the potential of line 40 to gate 51. Pulse b opens gate 46 so that if the core being scanned is switched, producing a pulse on sense line 28, trigger 36 is reset by this signal. If the core is plugged so that coil 34 is effective, no signal appears on line 48 and trigger 36 remains set. This being so, pulse c on line 52 is gated to switch trigger 37 and open gate 56 to information from the storage positions being scanned concurrently with the auxiliary plane. Finally, pulse d on line 44 resets trigger 36. The unmarked cores then set and reset trigger 36 without affecting trigger 37 until a second marked core is reached. The lack of an output on line 28 then leaves trigger 36 set with the result that pulse c is again gated to trigger 37, switching it (curve f) and closing gate 57 to the passage of information from the store. The cores may be wound so that only a marked core produces a pulse, in which case these pulses may be applied directly to trigger 37.

Abstract: 969,869. Electric motors with both members rotating. C. H. BRUNT. Dec. 5,1962 [Dec. 16, 1961], No. 45159/61. Heading H2A. [Also in Division G3] The speed of the output shaft 34 of an induction motor is regulated by controlling the rate of rotation of the primary member 25 by means of a variable bond, e.g. in the form of a liquid pump 19 whose inlet and outlet valves 39 may be opened to various degrees. The pumped liquid is circulated between the pump and a reservoir 13 through two tubes 38. The liquid in the reservoir is cooled by air forced through tubes 36 by fan 33. The valves may be controlled directly by a centrifugal governor (Fig. 9, not shown), or, as shown, by a servomotor. The servomotor (not shown), which controls the valves, is controlled by a speed-sensitive device 42, which may be a permanent magnet tachogenerator (Fig. 4, not shown). The output of the tacho-generator may be applied at points A, B of control circuit, Fig. 5. It is rectified and smoothed, and compared at R 7  with a steady potential from S 1  whose value may be controlled to set the motor speed by a variable resistor R 6 . The output is amplified by transistors T 1 , T 2 , T 3  and T 4 , again compared with the fixed potential, and used to feed the servomotor through terminals G and H. As an alternative to this circuit, the rectified output of the generator may be fed, through a controlling resistance to a rotating moving-coil relay which selectively engages switch contacts controlling the motor. The pump may be replaced by an air-fan or by adjustable permanent magnets. The device may be used for the differential winding of bobbins.

Abstract: 1411549 Automatic typewriters DATAPLEX Ltd 18 Dec 1972 [1 Oct 1971] 45833/71 Heading G4H In an automatic typewriter the actuation of the type bars corresponding to any two successive characters to be printed is arranged to occur an interval of time a part which depends on their spatial separation in the type basket. Characters in an 8-bit code are input to a buffer store 16 from, e.g. a keyboard, a computer, a magnetic card or punched tape, each character in turn being transferred to an 8-bit shift register 20. The character in 20 is fed to a coding translator 24, then back to 20: it is now in the form of a 6-bit code indicating the sequential position of the type bar in the type basket plus an upper/lower case bit and a parity bit. This character is input to a further register 30 whence it is transferred to a decoder 12 and a control circuit 40 so that the type bar may be actuated; a sensor 14 provides a feedback signal to 40 when the type bar passes through a predetermined position. The output from 30 (representing the character currently being printed) and the next input thereto (the next character to be printed) are fed to a subtractor 34 which calculates the modulus of the difference in positions of the two type bars; if this is greater than three then the next type bar is actuated immediately upon receipt of the signal from 14, but if it is three or less then actuation is delayed so as to avoid interference between closely situated type bars. It is stated that this arrangement (distinguishing only between more than three and three or less) is the optimum one for obtaining increased speed of operation.
