Abstract: 1491804 Diagnosis system COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE C11-HONEYWELL BULL 27 Jan 1975 [25 Jan 1974] 3495/75 Heading G4A In a data processing system St comprising processing units U1, U2, U3, Ut, transmitter members, e.g. member OE and receiving members, e.g. member OR, each including checking circuits CU1-CUt, COE, COR, one of the transmitting members OE includes diagnosis programs (on for example tape) for the units and members, in response to an error detected by one of the checking circuits the associated diagnosis program being fed to processing unit U2 where it is effected, one of the receiver members OR recording the result of the test on for example a display screen. If an error is detected in a processing unit, e.g. U3, means TU2 gains access to the test data and instructions forming the diagnosis program for this unit and held in a store SP in the member OE interface I tE . The unit U3 is then tested using interface I d2 , circuits ESD and interface I d3 . If check circuit CU3 in unit U3 detects an error the fault symptoms are fed to the unit TU2 via interfaces I d3 , I d2  and recorded in the member OR. If an error is detected in a transmitting/receiving member, e.g. Ot, the test information is transmitted from unit U2 via interface I d2  to unit Ut, processing in the unit Ut being interrupted if necessary so that means TU t  may perform the test. Processing unit U2 may be initialized, either as a result of a command signal CD or as a result of an error signal being transmitted to unit U2 over interface It during initialization of U1. If initialization of unit U2 occurs without an error the other members of the diagnosis system OE, OR are initialized in turn and the diagnosis program for U1 is loaded and performed after which U1 is initialized before operating programs for the system St are loaded and the unit U2 and the other units are initialized again before the system St becomes operational. If an error occurs in unit U2 during initialization of the unit or during operation of the system St a self-diagnosis routine is effected. If an error in a unit other than the units U1, U2 is detected either during initialization or during use the diagnosis program for this unit is fetched and performed, after repair a signal indicating satisfactory operation of the unit being transmitted from the diagnostic system to St. If there is a fault in the accessing of the diagnosis program or in the transferring of the results of a test the diagnostic system is stopped.

Abstract: 850,821. Nuclear fission reactors. SPITZER, L. Feb. 4, 1957, No. 3846/57. Class 39(4). Apparatus for raising a gas to high temperature, comprises a continuous magnetically permeable tube, a magnetic system for producing within the tube a unidirectional magnetic field parallel to the axis of the tube substantially throughout its length, and means for introducing atoms within the tube. The tube may be in the form of a figure of eight, the end hooks of which need not be coplanar but should preferably be in parallel planes, and is surrounded by a cooling jacket containing heavy water or lithium to slow down and absorb emitted neutrons. The tube is surrounded by a coil producing a unidirectional magnetic field, and may be surrounded by a further coil producing an alternating magnetic field, the coils being cooled by water, liquid air, or liquid hydrogen. As shown in Fig. 4 the tube 10 may be interrupted by an iron yoke 26 through which extend conical tubes 28 surrounded by coils 30 which divert part of the magnetic field through them. Thus charged particles approaching the walls of tube 10 are diverted into tubes 28 and strike the end caps 32 of these tubes when they are neutralised and pumped off through tubes 35.

Abstract: 490,051. Endless-belt conveyers; feeding and delivering sheets. JONES, K. W. Feb. 10, 1937, No. 3900. [Class 78 (i)] [Also in Group XVI] A conveyer for feeding to, carrying through, or delivering from, a machine, paper sheets, cards, or other articles, and simultaneously bringing each article into correct register with a side-lay, comprises a plurality of endless flexible belts each consisting of a plurality of strands which, between selected points spaced longitudinally of the conveyer, are twisted together to form a helical member, means being provided to engage the belts at each of said points and separate the strands whilst permitting forward travel of the belts, thereby effecting rotation about their axes of the portions of the belts between the said strand-separating means. In the embodiment shown in Fig. 1 in which sheets 4 are to be positioned against an adjustable side-lay 5, the conveyer comprises endless belts 1 passing round rollers 2, 3 and each consisting of two strands which are twisted together at the carrying side of the conveyer and separated at the rollers by engaging in grooves 2a, 3a. Alternatively, the strands may be separated by means of combs placed adjacent the rollers, by discs mounted on the rollers or by belts of another conveyer section engaging around the rollers. The rollers are synchronously driven by a chain 10 engaging sprockets 8, 9. The side-lay 5 may comprise an endless band driven through bevel and sprocket gearing by the driving gear of the conveyer. In the embodiment shown in Fig. 8 in which the conveyer carries sheets through a printing or numbering machine, the belts 1 are arranged in groups spaced apart to enable the underside of the sheets to be exposed to the appropriate parts 17, 18 of the machine, and belts 1a passing round intermediate rollers 23, 24 are arranged between these groups. In another arrangement, Fig. 12, the conveyer comprises two sets of belts 1, 101 having their strands wound in opposite directions whereby a sheet is first brought to register with a side-lay 5 and then into register with a side-lay 38 so as to be correctly positioned over machine elements 17, 18. In a modification, Fig. 13, the sheets are brought over these elements by the use of a single set of belts passing over intermediate rollers 37, 39, 40, 41, the strands of the portions of the belts between rollers 2, 37 and 39, 3 being wound in opposite directions. In an alternative arrangement for effecting reversal of side-register within the length of a single set of belts, the strands are separated by pulleys 43, 44, Fig. 14, whereby the strands rearwardly and forwardly of these pulleys provide oppositely-handed helices. According to the Provisional Specification, the belts may each comprise a twisted length of india rubber or like material of triangular, rectangular or of any other cross-section which when twisted will provide angles or ribs.
