Title: A random access data store
IPC: G11B5/55
Filed: 1967-07-11
Abstract: 1,129,415. Random-access stores. NATIONAL CASH REGISTER CO. 11 July, 1967 [18 Aug., 1966], No. 31757/67. Heading G4M. A magnetic card selected from a magazine is fed past an array of transducing heads 30, a pair of solenoids 56, 58 being selectively energizable to move the array of heads 30 transversely to the data tracks on the card whereby the array of heads co-operates with a selected combination of tracks on the card. The extent of movement effected by solenoid 56 is twice that effected by solenoid 58 owing to the off-centre pivoting of member 50 with shaft 46 carrying assembly 30. Damping of the head-shifting assembly is effected by springs 61, 67 and fluid introduced into chambers 59, 60, a flexible membrane 63 allowing for thermal expansion of the fluid. The store co-operates with a computer which produces binary coded commands designating cards to be selected and tracks on selected cards which are to be operated on. Each track may commence with an identifying label so that, on a first pass of the card past heads 30, correct track selection may be checked. In a'specific example, there may be 144 tracks on a card, and 36 heads in the assembly 30, the track selection command being decoded into a 2-bit signal for controlling solenoids 56, 58, and a 4 x 9 matrix signal for selecting the appropriate one of the 36 heads. A lamp/photo-cell arrangement initiates a read/write operation by way of an AND gate which is enabled when the same head assembly position is in use during successive passes, but which is enabled after a delay, sufficient to allow positioning of the head assembly to take place, when different positions are to be used in successive passes. Preferably the computer is programmed to select successive tracks from the same group as far as possible so that a maximum of four head assembly positions would be required to process an entire card.

Title: Servo system
IPC: H02P23/00
Filed: 1967-07-12
Abstract: 1,149,684. Automatic speed control. RADIO CORPORATION OF AMERICA. July 12, 1967 [Aug.2, 1966], No.32166/67. Heading G3R. A mangetic tape 10, upon which colour television signals are recorded, is associated with a head-wheel 16 driven by motor 15 which is also coupled to a tone wheel 22 producing a pulse for each revolution. A velocity error detector 24 compares the tone wheel pulse period which is the same as that derived from generator 42, with the fixed period signal generated by multi-vibrators 40, 41, and the error signal causes modulator 25 to apply appropriate power to each of the three phases of the motor 15. A generator 44 produces signals of the same period as the tone wheel pulses and is connected to phase error detector 45 which has little influence on the head-wheel modulator 25 until the motor 15 approaches standard speed. The input phase reference is a reference vertical signal from a local source and is fed to the detector 45 through a variable delay generator 50 which is set for a nominal delay corresponding to one revolution of the head-wheel when at proper speed. As the motor approaches the phase-locked condition so provided, another phase comparator 60 compares the reference vertical signal with a tape vertical signal and develops an error signal which modulates the delay of generator 50 so as to phase-lock these two vertical signals. A coincidence gate 64 then operates relay 65 to connect generator 50 to network 66 which provides a signal proportional to the phase error between reference horizontal and tape horizontal signals. When vertical locking is achieved, a horizontal rate sawtooth generator 67 is turned on and activates one input of comparator 68, the other input being derived from generator 69 in response to timing information from the tape. The output of the comparator 68 is supplied to network 66 and, in order to provide stable control, is also differentiated in unit 72 whose output, which is proportional to speed, is fed through stabilizing network 73 and adder 27 to the modulator 25. If the motor 15 is so disturbed as to cause the gate 64 to unlock, relay 65 switches back to reconnect comparator 60 to generator 50 and to turn off the generator 67. The whole reframing cycle is then initiated.

Drawings to Specification. [Classes 72 and 82 (i)] In the production of steel at suitable casting temperature which has been produced in a converter, dephosphorisation is carried out by known means either in the converter if it is a basic converter or in a ladle if the converter is either a basic or acid one and the molten steel transferred to an acid converter in which such a quantity of a reducing agent, such as silicon, whose oxide has a high heat of formation, is caused to act on the charge that by blowing for a very short time, e.g., 15 seconds, such a quantity of heat is evolved as to bring the steel to the necessary high temperature for casting. Before casting the steel may be deoxidised, e.g., by the process described in Specification 404,300. If the first treatment is carried out in an acid converter and dephosphorised in a ladle, which process may be carried out as described in Specification 405,633, the steel may be returned to the same converter for the reheating step The silicon may be used in the form of ferrosilicon and a protective substance such as manganese may be added, preferably simultaneously with the silicon and in the form of silicomanganese.
