Title: Control for a travelling crane
Inventor: BONNAURE PIERRE
IPC: G21C19/02
Filed: 1966-03-29
Abstract: 1,140,125. Controlling overhead cranes. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). 29 March, 1966, No. 13906/66. Heading B8B. A control system for an overhead travelling crane from which a load 1 is suspended includes a frame 4, the orientation of which is controlled by linkages 19, which is moved by a handle 11 in the direction in which it is desired to move the load. The reaction of the load against one or more of spring-loaded rollers 8 causes the latter to pivot and in so doing to close contacts controlling the crane traversing motors. The frame is split so that it can be closed round the load, a portion 5 being pivoted about a hinge 6. A push-button 12 controls hoisting movements. All controls may be either "on/off" or progressive. Oscillations of the load are damped by pneumatic dashpots connected one to each roller. The number of rollers provided need not be four. The frame may encircle the suspension cable 2 or a vertical pin or stud attached to the load rather than the load itself.

Title: Improvements in or relating to fuel elements for gas cooled nuclear reactors
Inventor: BARR PETER
IPC: G21C1/12
Filed: 1963-04-08
Abstract: 1,010,268. Fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 7, 1964 [April 8, 1963], No. 13995/63. Heading G6C. A nuclear fuel element comprises an outer container enclosing an annular fuel body and resilient means for urging into intimate contact the surfaces of the fuel and container, to improve heat transfer therebetween. The outer container 18 is of graphite; seven such tubes are mounted between an upper graphite grid 16 and a lower grid 17 to form a fuel assembly. Coolant gas enters the container 18 through a vent 22 in its upper metal cap 19, and passes through reactive graphite 24 and an orifice 25 to the fuel, and thence through porous material 34, 35 to a small bore pipe. The fuel is in the form of annular rings, each ring formed by a number of segments and urged radially outward by a helical graphite member 26c or by a tubular spine 26a having a longitudinal split 26b. The fuel assembly is provided with a ring of electrical contacts 39, e.g. for thermocouple leads. A gas cooled reactor in which the fuel elements described can be used is helium cooled and utilizes a reflector of graphite blocks which are cooled by incoming coolant; moderation is by the graphite fuel element casings. Capillary tubes for each fuel element of each fuel assembly pass through coupling, pressure measuring and filtering devices and thence to the reactor coolant inlet; by this means the integrity of the fuel tubes may be monitored since a failure in a fuel tube will give rise to a marked purge line pressure increase.

Abstract: 657,938. Liquid-fuel burners. MASCHINENFABRIK OERLIKON. May 27, 1949, No. 14276. Convention date, Nov. 6, 1948. [Class 75(i)] A fluid fuel burner, applicable for gas turbine plants, has the atomizing air divided into partial streams which are directed eccentrically of the fuel jet and in an oblique manner whereby the air jets interweave with each partial air jet passing underneath a preceding air jet and above a succeeding air jet and each air jet impinges on a corresponding circumferential portion of the fuel jet. The apparatus comprises a housing- 8 formed with air passages 9 in a conical surface of its end wall, and a fuel nozzle 10. Air passing through the annular space formed between fuel nozzle 10 and housing 8 and passing thence to the passages 9 in the conical end wall is split into a number of streams 13, 14, 15 and 16, Figs. 5 and 6, which are directed obliquely and eccentrically of the fluid fuel stream 17 issuing from passage 11 and each of which impinges on a circumferential portion of the fuel stream in such a manner that each air stream, for example 13, passes behind the preceding air stream 16 and in front of the succeeding air stream 14 when impinging on a corresponding sector of the fuel stream. Regulation of the burner and alteration in the shape of the resultant jet is effected by retracting the nozzle 10 thus causing the atomizing air flow to change into a more central axial flow and restricting the fuel flow by pressure alteration at the nozzle.

Convention date, May 27, 1930. Drawings to Specification. [Class 96.] The transparency of paper is enhanced by subjecting it while moist to compression between hard rolls, which reduce the moisture content but not sufficiently to cause injury thereto during an ensuing compression between soft rolls, and finally to pressure between hard rolls which reduce the moisture content to the percentage requisite to maintain the strength of the paper. The first series of hard rolls reduces an initial moisture content of about 30 per cent to one of about 12 per cent for the pass age through the series of soft rolls, the final series of hard rolls reducing it to about 6 per cent. Fly rolls may co-operate with the main rolls, each of which is frictionally driven by the next roll in the series and any or all of the hard or fly rolls may be heated internally.
