[Also in Groups XX and XL(a)] In analysis apparatus of the type in which a specimen emits X-rays under the influence of a focused electron beam and these X-rays are reflected from a crystal at a measured angle to determine the nature of the specimen, the latter is mounted in an adjustable holder so that it can be examined visually in one position and bombarded with electrons in another position. In Fig. 2 the specimen can occupy two alternative positions 18 and 25, one for examination through a microscope 17 and the other to receive electrons from the gun 26 and focusing lenses 29, 31 (e.g. as in Specification 847,266). The rod 16 can be moved axially and rotated to bring any desired part of the specimen under the cross wires of the microscope (Fig. 3, not shown) and then rotated by a predetermined amount to bring the same part into the electron beam. The holder 15 can carry a number of specimens at different angular positions for successive examination, and one of these may be a standard. By moving the rod 16 synchronously with a recording chart (Fig. 4, not shown) the whole area of a specimen can be scanned. The apparatus is mounted on a table 1 (Fig. 1) which carries two arms 5, 7 and associated linkwork so that the angular movement of arm 7 is always double that of arm 5. The X-rays emitted by the specimen, 2 are reflected by a crystal at 3 and received in a Geiger counter or other detector at 4.

Abstract: 650,616. Flexible ladders. HUDSON, A. N., STUDD, S. D., and WILLIAMS, W. Oct. 29, 1947, Nos. 28848 and 32409. [Class 20(ii)] A flexible ladder, e.g. a fireescape, has side members, formed of alternate main links 10, Fig. 1, and U-section short links 11, alternate links 11 in each side member being all oppositely disposed to the other links 11 so that the ladder is constrained by rule-joint action to fold in zig-zag formation with its main links 10 superposed as shown in Fig. 3. The rungs 14, Fig. 1, which are channel-shaped with folded-over edges, are welded to the links 11 and W-shaped wallengaging members 16 are secured to the links 11 and rungs 14. The uppermost links 10 are connected to a pair of plate-link chains 9 extending across a window sill 20 and secured to anchorage brackets 21 within the building. A curved tube 25, detachably mounted at the window serves as a guide for the ladder when extending it. In a modification shown in Fig. 4, the main links 10 are about half the length of those shown in Figs. 1, 3 and alternate U- shaped links 11 only are connected by rungs 14 and wall-engaging members 16: In the collapsed ladder in this case, all the superposed members 16 are disposed within the stack which, for a given length of ladder, is approximately twice the height and half the depth of the stack shown in Fig. 3. Where a projecting ledge causes the ladder to hang clear of the wall means may be permanently mounted on the wall for securing the ladder. Thus a pair of toggle links 31, 32, Fig. 5, the link 31 being hooked at 33 for engagement with a rung 14, is actuated by a lever 36 which is locked by a pin 38. The lower end of the ladder may be anchored to the ground as shown in Fig. 7 and may be extended as a chair or provided with a harness or cradle. The attachments of the side members within the building may be provided with spring shock-absorbers. According to the first Provisional Specification the ladder may be housed in a casing on the outside of the building and may be raised by cords in the manner of a venetian blind.
