Title: Magnetic memory arrays
IPC: G11C7/00
Filed: 1962-04-16
Abstract: Writing into a magnetic storage matrix is effected by coincident pulses of small amplitude, long duration, and slow time, while reading is carried out by high amplitude pulses of short duration, the write pulses being applied through low-pass filters, and the sense circuits incorporating high-pass filters so that the write pulses, due to their low-frequency harmonic content, are unable to block the sense amplifiers, and the read pulses, due to their high-frequency content, are unable to influence the write pulse generators. The arrangement enables a read operation to closely follow a write operation, or for reading and writing in the matrix to take place simultaneously. A matrix store of the " twistor " type as described in Specification 877,731 is shown in Fig. 1, the storage elements being constituted by discrete regions along magnetic conductors 10 having a helical flux paths 11, each region being defined by the intersection of a column conductor 9 with a magnetic conductor 10. A binary word is written into a selected magnetic conductor 10 by applying coincidence half-write pulses to one magnetic conductor 10 and selected column conductors 9. As the write pulses are essentially of low-frequency harmonic content, the column sense amplifiers 7 are each isolated by respective high pulse filters 8. Read out of a selected magnetic conductor is effected by a full switching pulse of opposite polarity which is applied by a read generator 14. As the read pulse is composed of high-frequency harmonics, the induced output in any column conductor due to field reversal of the adjacent portion of the energized magnetic conductor is able to pass to the associated sense amplifier 7 over a high-pass filter 8. The read pulse is without effect on the write pulse generators 5 and 12 due to the provision of lowpass filters 6 and 13. Annular cores 21 and a separate sense winding 20 are used in the second embodiment, Fig. 3. As previously described, half-write pulses are coincidently applied from write sources 26, 27 over low-pass filters 24 and 25 to record a bit in a selected core. Reading of any other core, even in a write-pulsed column or row, can take place simultaneously by applying coincidence half-read pulses having a highfrequency harmonic content from read source 28 and 29, since the sense amplifier 23 is connected by way of a high-pass filter 22 to the sense conductor and responds only to highfrequency stimulation.

Title: Nuclear reactor
IPC: G21C5/10
Filed: 1967-09-15
Abstract: In an integral nuclear reactor, the helium gas cooled core and the steam generating heat exchangers are mounted together in a prestressed concrete pressure vessel. The core support system and the interior system of the pressure vessel are cooled by the flow of gas prior to its entry into the core. The gas flows downwards through the core, the graphite blocks of which are thrust downwards into engagement with the core support plate. The exchangers may be removed through an access duct, in the vessel lower end wall, which is normally closed. The vessel is a vertical cylinder enclosing a cylindrical chamber, the lower region of which is occupied by the exchangers comprising evaporatoreconomizer, superheater and reheater, and coolant pumps, and the upper region of which encloses the core. The latter rests upon a horizontal bed which is supported, above the heat exchangers, upon vertical columns. The latter are hollow and are cooled internally by about 15% of the main coolant flow. The core is cylindrical and is formed of columns of graphite blocks in which fuel rods are embedded. Vertical passages are formed in the graphite to accommodate the gas flow and the control rods. Fixed orifices control the gas flow through the core. Reflector blocks surround the core and lateral restraint is provided by an enclosing steel cylinder. The core structure is carried on the horizontal bed by vertical graphite posts which have spherical ends to permit differential thermal dimension changes within the structure.

Title: Method for moving variable data during operation from a first store field to a second store field in the data store of a computer
IPC: G06F9/48
Filed: 1968-12-17
Abstract: The invention relates to a programmed computer. A computer for use in controlling a telephone exchange works on different priority levels, work in progress being interrupted to allow working at different priority levels commencing with the highest priority level. Occasionally a memory area storing data concerning for instance the condition of devices B must be increased as more devices are brought into use. This may involve transfer of the data to a new memory area the transfer taking place on the lowest priority level. Since the transfer can be interrupted it is possible that data that is in the process of being transferred is altered in the initial location and stored unaltered in the final location. The computer is programmed to overcome this. An instruction store IM holds an instruction at address A1 which causes a protection limit GS to store the initial and final addresses of the memory area FB to be transferred. The instruction in A2 causes GS to raise the priority level temporarily whenever an information item address is in the protected range. A3 starts the data transfer, program commencing: in address Ap and causes the instructions held in addresses Ap to Ap + 7 to be performed, the instruction in Ap + 2 as indicated by line 5 causing jump to Ar if the bit is the first of FB and to Ap + 3 otherwise. The bits of field FB are successively transferred to the field FB1 in data memory DM. If an interrupt causing change of data in the field FB occurs GS causes change of priority level control by altering the contents of register ILR to put a bit in level P (the highest priority level). All other interrupts occur only on lower levels S, A, B or C, the latter being the transfer level. As shown in Fig. 4 the interrupt was on level B at time T1 and at instruction address H. Hq causes, via line 12 and GS, the highest priority level to be set and storage of information required to continue the instructions on level B in field FU. An instruction at address C is obtained and causes writing of the required data at the address in FB and at the corresponding address in FB1. Then the level is lowered and the level B interruption continued. To ensure that all data is transferred an auxiliary control field FQ is also provided. When devices included in a connecting link are periodically sampled information regarding the busy condition arises without knowledge of the new address so the field FQ is set up with positions corresponding to the number of transferred items which positions are all set to 1 at the beginning of the transfer and are set to 0 when the positions are free.. At the end of the transfer the field is examined. If any positions are not zero then the remaining positions are updated.

Patent ES-427953-A1 (ES)
Title: Peak detector
IPC: G11B20/10
Filed: 1974-07-07
Abstract: A peak detector generates a signal representing the occurrence of a peak in an input signal waveform each time the slope of the input signal waveform reverses and travels through a dead zone defined by the difference between two different reference voltages. The dead zone which prevents short term reversals in the input signal waveform due to noise and other aberrations from generating signals representing valid peaks and which is defined by the difference between the two reference voltages is easily adjusted such as by varying the value of a single resistor in one embodiment to adapt the peak detector circuit to different input signal waveform situations. A common terminal which is coupled to the two different reference voltages through opposite voltage-responsive devices has a voltage which varies directly in response to the input signal waveform as applied thereto by a voltage coupling device such as a capacitor. The voltage-responsive devices maintain the voltage of the common junction within the range defined by the two different reference voltages by conducting whenever the common junction voltage equals either of the reference voltages. Alternate conductions of the voltage-responsive devices are used to trigger a bistable device which provides an accurate representation of the peaks of the input signal waveform.
