Abstract: 1,159,609. Detecting radiation. COMMISSARIAT A L'ENERGIE ATOMIQUE. 16 Nov., 1966 [27 Nov., 1965], No. 51368/66. Heading H5R. A gas-filled radiation detector is operated so that instead of an incident particle or photon of radiation producing a spark, the voltage between the electrodes is reduced to a level such that the incident photon produces an avalanche of electrons without the spark, and the slight luminosity of these phenomena are intensified via a standard photo - electric image intensifier, and the resulting image recorded, e.g. with a photographic camera. In a preferred embodiment (Fig. 2) a radioactive source 16 shielded by a plate 18 is placed in front of a detector A which consists of a sealed chamber containing a thin metallic cathode 6, e.g. a strip of Al foil, an auxiliary electrode 12, in the form of a metallic grid, and a transparent anode 14 having a conductive surface, e.g. a mesh or a conductive glass, all these electrodes being parallel to each other, the chamber being gas-filled, e.g. with a mixture of xenon and methylol having partial pressures of 730 and 30 torr respectively. The cathode 6 is supported by a metal plate 10, having perforations which effectively collimate the beam from source 16, and the chamber has a transparent top closure so the interior is visible. The cathode and plate 10 are at ground potential, whilst auxiliary electrode 12 and anode 14 are respectively coupled to a low voltage source and a high voltage source B.T. and H.T. through resistors 20 and 22. A photon from source 16 incident on cathode 6 gives rise to electrons which pass through grid 12 to initiate avalanche phenomena in the gap, given a suitable potential. The slight luminosity of these phenomena is amplified in an image intensifier being focused on the photo-cathode thereof by lens 30. The resulting intense image on screen 32 may be photographed with camera 24.

Abstract: 1505832 Welding by pressure WELDING INSTITUTE 27 Nov 1975 [2 Dec 1974] 52126/74 Heading B3R [Also in Division F2] In a method of friction welding coaxially nested first and second members, such as 24, 23, presenting circular joint interfaces, relative rotation is imparted about their common axis, and at least one of the members is subjected to uniformly distributed pressure which is perpendicular to the axis and directed to move the members into frictional contact. The method can be applied to welding two pipes 2, 3 and a ring 1 (Fig. 1) by rotating the ring 1 and applying inwardly directed pressure (Fig. 1) or outwardly directed pressure (Fig. 7, not shown), welding gudgeon pin bushes, pistonrings and a Cu-alloy combustion chamber ring to an Al piston (Fig. 9, not shown), and welding a ring inside a pipe using a reaction annulus (Fig. 6). In apparatus (Fig. 3) for joining the two pipes 2, 3 (Fig. 1), the pipes are gripped by collets 4, 5 and the ring is gripped by twelve jaws 9. Each jaw 9 is mounted on a guide 10 and can be moved radially of the pipes 2, 3 by an oil-actuated piston 11, a tapered inner surface of the piston acting on the tapered outer surface of actuating members 12 attached to the jaws. The jaws rotate relative to the pipes and inward pressure is applied to the ring to provide frictional heating. On cessation of the rotation, the inward pressure is maintained or increased to a larger forging pressure and an axial load may be applied to the pipes. An expanding mandrel 18, 19 supports the pipes during welding. External flash may be removed by serrations on the jaws 9 (Fig. 5, not shown). Internal flash may be removed by axial movement of an internal plug having an annular groove (Fig. 8, not shown) Contrarotation of the workpieces, inertia friction welding and the use of an Al ring to join steel pipes are referred to.
