Title: Improvements in or relating to data processing systems
IPC: G06F13/16
Filed: 1970-06-15
Abstract: 1276590 Digital data storage BURROUGHS CORP 15 June 1970 [30 June, 1969] 28809/70 Heading G4C A digital electric data processing system comprises a sequential access data storage device (e.g. one or more magnetic discs), and first and second multi-word stores 220, 240, wherein access request words for the device are entered in the first store 220, are transferred to the second store 240 as the corresponding device addresses are about to be available for access, and are transmitted from the second store to the device as the corresponding device addresses become available for access. Prior art systems used a single store whereas the present system uses a cheap, high capacity, slow access time, first store 220 and a low capacity, quick access time, second store 240, which latter store can be completely scanned before the current address of the disc is incremented by 1. When a certain address of the device is about to be available for access as determined by comparator 260 the request(s) is forwarded to the second store 240. For each address of the disc the store 240 is scanned and if a request has that address the request transaction is performed or if the device is unavailable for some reason the request is transferred back to the first store. The first store also has an input data buffer area controlled by logic 225. Comparison of addresses may only use the more significant address parts and a more detailed circuit is described (Fig. 3, not shown). A disc file controller using the above system is also described, Figs. 4 and 5 (not shown), include a binary to BCD converter. Further storage devices may also be provided and the format of various request words is described (Fig. 6, not shown).

Title: Data storage arrangements
IPC: H01L41/00
Filed: 1975-07-10
Abstract: 1515547 Controlling light INTERNATIONAL BUSINESS MACHINES CORP 10 July 1975 [22 July 1974] 28995/75 Heading G2F [Also in Divisions G4 and H3] A data storage device includes a material con-  taining defect sites on which electrons can be trapped, a means (lamp 16) to fill the electron traps, and means to produce in the crystal r.f. acoustic and r.f. electric pulses which interact to record data as a spatial pattern of trapped electrons. The crystal may be Piezo-electric CdS doped to provide electron traps which are filled by illuminating the crystal with visible light. A first r.f. pulse 12 is then applied which, by virtue of the Piezo-electric nature of the crystal, induces an acoustic wave in the crystal. The application of an electric r.f. pulse 14 causes the acoustic and electric fields to interact to store a charge pattern, in the form of distributed trapped electrons, representing the correlation (see USA Specification 3760172) of the two signals. By applying an r.f. pulse 18 an output pulse 12' constituting the convolution of the stored charge pattern and pulse 18 is obtained. The frequencies used range from 5 MHz to GHz. The storage effect is said to be temperature dependent, ie 2 milliseconds at 200K and months at 4K. In a further embodiment a pulse is applied to a transducer which generates an acoustic pulse in the crystal to which a short intense electric pulse is applied to store the acoustic signal. As an autocorrelator a single pulse generates acoustic and electric fields to store the autocorrelation of the pulse. When a short delta pulse is applied the autocorrelator signal is read out. If an object is located between the transducer and the crystal the acoustic signal is diffracted and a hologram is stored. Associated with the stored charge pattern is a variation of refractive index to enable the hologram to be read using a laser beam and a suitable detector. If the frequency of the acoustic signal is W 1 and of the electric signal W 2  then storage occurs with W 2 =W 1 /2n-1. If a D.C. pulse is applied with the electric signal then W 2 =W 1 /n, n= 1,2,3, ..... etc.

Class 100 (1) Sheet-registering devices:- In front lay mechanism for sheet-feeding apparatus, the front stops, means for operating them, and a front lay catch of an associated unlatching mechanism are mounted on the front lay shaft. The front stops 9 (not shown) are secured to a shaft 3 mounted in the feed table 1 and provided with a stop lever. A lever 7, freely mounted on the shaft 3, has a runner 12 which is urged by a spring 10 against a cam 13 secured to the drive shaft 2, and a boss 14 on the lever is urged into contact with a similar boss 15 on a lever 6 by a spring and pin arrangement 16, 17, the pin 17 being secured to the boss 15. The lever 6 is freely mounted on the shaft 3, and has an abutment 18, on the opposite side of the shaft 3, provided with a stop-screw 19 engaging an abutment 20 formed on a lever 8 secured to the shaft 3. Thus, when the shaft 2 is rotated, the shaft 3 is rocked through the resilient connection 14-17. The boss 21 of the lever 6 is formed with a catch 22 adapted to be engaged by a lever 23, pivoted to the table 1 at 24, urged upwardly by a spring 25. This lever 23 is engaged by a stop 27 depending from an arm 28 fixed to a detector shaft 4 which is controlled by sheet-detectors. In operation, when a sheet is correctly positioned against the front stops 9, the latter can be lowered to allow the registered sheet to be fed, since the sheet-detector shaft 4 will have been rocked and the stops 27 will nave released the lever 23 from the catch 22 on the lever 6. If a sheet is incorrectly positioned on the feed table 1, the shaft 3 cannot be rocked, and the lever 7 merely compresses the spring 16.
