In a computer system in which a plurality of input-output channels communicate with a main memory by way of a central control unit allocating accesses to the main memory by the input-output channels, and a plurality of inputoutput lines are selectively coupled to the channels by means of a multi-line control means, an address memory stores two addresses for each input-output line and whenever an input-output channel gains access to the main memory the corresponding first address is utilized for addressing purposes, is incremented by a predetermined amount, is compared with the corresponding second address and is rewritten into the address memory, a signal being presented to the central control unit when an equality comparison result is obtained. The invention is applied to the time-sharing computer system described in Specification 1,172,494, in which control code characters in transmitted data are detected by the line control unit concerned to effect necessary control functions, for example, ending transmission. The present invention provides so-called transparent input-output commands in which response to the detection of said control codes is suppressed, e.g. for transmitting complete programmes from one computer to another, and provides alternative means for ending the transmission. For this purpose, address memory 58 contains two address locations for each device communicating with the main memory 11 and a compare circuit 68 is provided for comparing the incremented address in address register 41 with the corresponding second address in memory 58, a line 70 being utilized for informing central control unit 12 when equality is obtained. The unit 15 may comprise a second computer with which a complete programme is to be exchanged. The invention may be applied to single-line control units 20, 26 also.

Abstract: 726,022. Electric tests. SOCONY-VACUUM OIL CO., Inc. May 28, 1953, No. 14913/53. Class 37. [Also in Group XXXVIII] The invention relates to the calibration of apparatus for investigating the earth formation adjacent to a well bore wherein the changes in the impedance of a coil located in the well are split into resistive and reactive components representing conductive and magnetic earth formations. As shown, a solenoid 10 located in the well bore forms one arm of a bridge network 11, fed from an A.C. source 14, whose output is taken through an amplifier 18 to phase-sensitive measuring circuits 21, 23, also fed with reference signals from the A.C. source 14 through a phaseadjusting circuit 26, the reference signal to circuit 23 being adjusted by a circuit 29 to be 90 degrees out of phase with the reference signal to circuit 21. A four-position switch 36 is provided at the surface, whereby in position 1 a battery 37 energizes a relay 44 through rectifier 43 to connect a condenser 46 to a coil 47 coupling with the test coil 10, so that the output of bridge 11 contains an additional reactive component. In position 2 of switch 36 the condenser 46 is removed and circuit 26 is adjusted to give the same reading on meter 24. In position 3 of switch 36 a resistor 45 is added to coupling coil 47, and circuit 29 is adjusted to produce no change on meter 25. Finally in position 4 of switch 36, the amplifier 18 is fed from a network 54 which simulates the signal from the bridge 11 obtained when coil 10 is in air, thus giving the zero indications on meters 24. 25. The calibration method described may be used with acoustic well-logging apparatus wherein the search coil is located inside a magneto-strictive nickel cylinder which produces acoustic waves, the nature of the surrounding earth formations producing impedance changes in the search coil which may be analysed as above. The test resistor 45 and condenser 46 in this apparatus may alternatively be selectable electro-mechanical loading devices for the magneto-strictive cylinder.

Title: Curing of rubber latex and the productionof articles therefrom
Inventor: POUNDER DONALD WHITWORTH
IPC: C08J3/28
Filed: 1956-05-15
Abstract: Natural or synthetic rubber latex is cured by subjecting it in the form of an aqueous dispersion to irradiation by high energy electrons, X-rays, alpha, beta, or gamma rays, protons, deuterons, or neutrons.  The latex may be of Hevea brasiliensis, kok-saghyz, gutta-percha, bata, a polymer of a diene hydrocarbon, e.g.polybutadiene, or a copolymer of a diene with another compound, e.g. butadiene-acrylonitrile or butadiene-styrene copolymer, or a polymer of a substituted conjugated diene containing the group CH2 : C.Cl, e.g. polychloroprene.  The prefered sources of radiation are linear accelerators and radioactive cobalt, and the preferred dosage of radiation is 3 X 106 to 1 X 108 Roentgens.  The cured latex may be used for producing rubber articles without the addition of sulphur or other curing agent.  Articles may be formed by dipping with or without the use of coagulant.  Foam rubber may be prepared by whipping the latex to a froth after addition of a soap and then gelling the froth, and rubber threads may be prepared by extruding the cured latex through jets into a coagulant.  In all cases the product is dried either at room temperature or at about 40 DEG C. Examples are described in which (1) natural rubber latex is exposed to gamma radiation from radioactive cobalt, (2) natural rubber latex is exposed to a beam of high energy electrons from a linear accelerator, and (3) a latex produced by the emulsion copolymerization of butadiene and styrene is exposed to gamma radiation from radioactive cobalt.
