Title: Characterisation of Radioactive Waste
Inventor: ORR CHRISTOPHER HENRY
IPC: G01T1/16
Filed: 2009-07-24
Abstract: Methods and apparatus are provided for improved screening of containers of radioactive waste so as to classify them according to certain grades of waste, e.g. LLW, PCM. The approach uses detectors sensitive at a first energy range to detect higher energy radiation. This may be from plutonium within the waste or from a separate source, when the waste is located in between source and detector. A threshold value is provided on the basis of which waste is classified as clearly or possibly containing plutonium. Detectors sensitive at a lower energy corresponding to plutonium decay products are also used to provide a second threshold value for classification.

Filed: 1920-04-12
Abstract: 167,535. Spence, W. L. April 12, 1920. Steering-gear; deflectable axle-ends and intermediate connections therefor.-Comprises a method of applying leaf springs in place of cranked levers for effecting controlling movements. (1) In one form of the invention, applied to vehicle steering-gears, a tubular steering-pillar B has secured to its lower end a spindle A screwed with intersecting right and left-hand threads, with which engage two half-nuts C, D, threaded right and left respectively and non-rotatably sliding in an oil-bath casing E broached to a square or hexagonal cross-section. Extensions C', D' cf the half-nuts carry oil-pads L where they bear on the pillar B and have secured to them leaf springs G, H, the free ends of which are rigidly united by a head K carrying a lug J so inclined that its ball-and-socket connection to the draglink of the steering-gear depends substantially vertically, whereby retention of oil in the joint cup is facilitated. Rotation of the steering-pillar, by traversing the parts C, D in opposite directions, causes flexure of the springs, as shown diagrammatically in Fig. 4. The springs G, H may be locally strengthened by short leaves P, Q, and may be backed, where they are to be rigid, by further leaves R, preferably corrugated. They may be guided, as shown in Fig. 4, by rollers T and held together by auxiliary springs V. The casing E isclosed by a cap F, which grips a ring M, itself gripped between two thrust washers N by the pressure of a coned spring-washer O. The spindle A is drilled up for increased oil space. (2) In another form, the usual steering-linkage is dispensed with and the front-wheel axles or bearing- hubs are directly attached to blocks, each uniting the free outer ends of a pair of leaf springs, their inner ends being connected in fore and aft pairs across the vehicle by stiff rack or other bars, which slide on roller chains in the axle casing, and can be simultaneously traversed in opposite directions for steering.
