Title: Data processing systems
IPC: G06F11/22
Filed: 1975-05-07
Abstract: 1509805 Data transmission: master and slave systems SIEMENS AG 7 May 1975 [14 May 1974] 19076/75 Heading H4P [Also in Division G4] In a data processing system comprising a group of addressable peripherals connected to a central unit via a common bus, addressing faults, e.g. double addressing faults where more than one peripheral responds to a given address, are checked by causing the central unit to emit an address and a checking command which causes any responding peripheral to emit its address to compare the received address with the transmitted address, if the comparison is positive, to repeat the process but with the addresses inverted, and in the event that either comparison was not positive, logically to link the received addresses and the true and inverted transmitted addresses to produce the address of the faulty peripheral which caused the double addressing. The common bus operates to link messages from two or more peripherals in a Boolean AND manner, i.e. a logic 0 from any peripheral clamps the bus to logic zero. As described the transmitted and received addresses and the commands from the central unit are fed in parallel over respective ones of three sets of lines forming the bus. Assuming a first peripheral A has an address 00111 and a second peripheral B an address 01111 and that peripheral B has a double addressing fault in respect of peripheral A, the first received (true) address Q will be (00111 and 01111), i.e. 00111, which is correct. However with inverted addresses the received address R is 10000 instead of 11000. When either comparison fails the inverse address of peripheral A is ORed with Q which in this case gives 11111. A is then ORed with R which gives 10111. If both operations give all 1's then the fault F can not be determined and operations cease. If either operation gives any 0's as is the case here A is ORed with Q which gives 11111 and a preliminary result DA/F (double addressing or indeterminate fault) is made. If any 0's appeared in the previous result A is ORed with R and if all 1's causes the preliminary result DA/F to be made. Otherwise the result F (indeterminate fault) is reached and checking is stopped. From the preliminary result DA/F the value Q OR(R OR A) is calculated if both Q and R exist and is compared with the addresses of all the peripherals except A, a comparison, in this case 01111, (the address of B) indicating the double address faulty peripheral. However if the initial comparison of the true returned address(es) failed R is not available and no calculation of the address of the faulty peripheral can be made.

Title: Method of and apparatus for the transmission of heat from one gas to another
IPC: F25J3/06
Filed: 1926-08-03
Abstract: 256,271. Ges. fur Linde's Eismaschinen Akt.-Ges. July 31, 1925,. [Convention date]. Cooling gases by direct contact with cooling-medium.-In a process for the liquefaction or purification of gases heat is exchanged between the compressed gas and the expanded gas by means of a liquid circulating in a closed cycle. Compressed gas, e.g. ethylene, at the temperature of cooling-water enters a cooler A at a, and is then passed through an expansion valve V. The gas is in part liquefied and the unliquefied part passes into the column B. Toluol is supplied from a tank E to a pump P and thence to the column A where it cools the compressed ethylene. The toluol then passes, still as liquid, through a throttle valve D to the top of the column B, where it is re-cooled by the out-flowing low-pressure ethylene, and flows back to the pump P. A modified system is described in which part of the liquid is interrupted at an intermediate point in the column A and returned to an intermediate point in the column B. The application of the process to the separation of air into oxygen and nitrogen is described. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also the applcation of the process to the exchange of heat between gases generally. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to fuel materials for nuclear reactors

IPC: G21C3/62
Filed: 1966-05-02
Abstract: 1,130,972. Uranium/niobium carbide. GENERAL ELECTRIC CO. Ltd. 19 April, 1967 [2 May, 1966], No. 19220/66. Heading C1A. [Also in Division G6] A nuclear fuel material is composed of U, Nb and C in relative atomic proportions in the range(51-x)%U; x%Nb 49%Cto(48-x)%U: x% Nb 52% C, where x is in the range o.1 to 8.o atomic per cent, and consists wholly or mainly of a (U, Nb) monocarbide solid solution. In a modification, the U is partly or wholly replaced by Pu. The fuel material may be manufactured by arc melting a mixture of U, C and Nb, in the required relative proportions. It is possible to introduce the Nb by using a Nb electrode for the arc melting of a U-C mixture; however, it is preferred to use a graphite electrode and to include the required amount of Nb in the initial mixture. As an alternative to using a U-C mixture, preformed UC can be used as a starting material. Alternatively, the fuel material may be manufactured by pressing a powdered mixture of U, C and Nb, or of UC and Nb, in the required relative proportions, to form a compact of a desired shape and size, and sintering the compact. The partial replacement of U (or Pu) by Nb in the fuel material results in a marked improvement in its creep resistance.
