Title: Parity error recovery in computers
IPC: G06F12/16
Filed: 1973-07-16
Abstract: 1389500 Recovery routines SPERRY RAND CORP 16 July 1973 [17 July 1972] 33679/73 Heading G4A A data processing system having independently accessible storage segments in a store 49 (Fig. 3), effects a first parity error recovery rountine held in one of the storage segments when a parity error is detected in data or addresses relating to a storage segment in which the first parity error rountine is not stored and a second parity error recovery rountine held in a different segment of storage if the erroneous information relates to the storage segment in which the first routine is stored. Data read from a storage segment in response to an address entered into register 24 is fed to an input data register 48, a parity generator 27 deriving a parity bit for each half word of this data for comparison in error logic 26 with parity bits read from the store. Circuitry 30 performs a parity check on read or write data supplied to the stores and feeds its output to the error logic 26 which is connected to interrupt priority logic 23. A comparity 21 compares the most significant bits of the address in register 24 with the address in register 25 of the first parity recovery routine and if coincidence does not exist the priority logic 23 transfers the contents of register 25 to interrupt address register 22 together with a pointer to give the absolute address. Otherwise the contents of auxiliary parity routine register 20 are fed to the register 22 together with a pointer.

Title: Improvements in or relating to radio receivers
IPC: H03F1/36
Filed: 1935-12-10
Abstract: 468,784. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and RUST, N. M. Dec. 10, 1935, No. 34217. [Class 40 (v)] In a radio - receiver the first tunable circuit is preceded by a valve having a semi-aperiodic input circuit and employing negative reaction applied by a semi-aperiodic impedance of the same nature as the input circuit, so that the first tunable circuit is disassociated from the aerial and may be gang tuned. The provision of negative reaction by the impedance 5 common to the input and output circuits prevents cross-modulation and if the impedance is such as to increase at frequencies outside the tuning range interference at these frequencies is minimized. Fig. 3 shows an arrangement in which the aerial is tapped down on an aperiodic input circuit 10 with a similar circuit 5 provided to give negative reaction. The circuits 5, 10 comprise inductance and capacity resonant to the middle of the desired tuning range shunted by a resistance of such a valve as to give a flat topped impedance-frequency curve for the tuning range. The output circuit 7 is tuned and if a high-frequency pentode valve or an electron beam valve as described in Specification 403,973 or other valve of high internal impedance is used appreciable gain may be obtained from the stage. The aperiodic circuits 5, 10 may be arranged to give a double humped characteristic and the first tuned circuit a peak between the humps in a superheterodyne receiver so that if the intermediate frequency amplifier gives a double humped characteristic the overall characteristic is a substantially flat-topped band pass curve.
