Abstract: 652,547. Turning. WARD & CO., Ltd., H. W., and HOOSON, G. C. Aug. 25, 1948, No. 22423. [Class 83 (iii)] In a lathe, particularly a capstan lathe, in which a slide such as a capstan slide is manually movable through rack- and-pinion gearing the latter is combined with a locking device in the form of a unidirectional clutch adapted to prevent undesired return movement of the slide. A capstan slide carries a rack c, Fig. 1, with which meshes a pinion b carried at the end of a shaft a journalled in the machine bed. A hand-operated member e is keyed to a sleeve g which is freely rotatable on the other end of shaft a. The sleeve is provided with projections h which engage in recesses j in a member i keyed to the shaft a. Rollers n, Fig. 2, are spring-pressed into wedging relation between the member i and a surrounding stationary ring o and these prevent a force on the slide from moving it in reverse direction after adjustment. Rotation of the hand-member e through the projections h, pushes the rollers out of wedgeengagement and enables the slide to be operated reversely by the hand levers f. On forward adjustment of the slide by the hand levers the projections h engage the free ends of the recesses j and the wedge-pieces are inoperative in this direction. The sleeve g and complementary clutch-member i may be locked together by a bolt p.

Title: Improvements in or relating to instruments for the automatic integration, evaluationor analysis of graphs
Inventor: HAMBLETON JAMES
IPC: G06K11/02
Filed: 1957-07-16
Abstract: 861,228. Photo-electric indicating-apparatus. JOYCE, LOBEL & CO. Ltd. July 15, 1958 [July 16, 1957], No. 22445/57. Class 40 (3). [Also in Group XIX] A double-beam automatic recording reflectance densitometer suitable for use in electrophoresis, chromatography and spot test analysis comprises a source 10 of light which is split into two beams 11, 12. The beam 11 passes through a collimating lens 13 and is reflected by a mirror 14 across the path of a rotating shutter 15, driven by a synchronous motor 15a, which interrupts the beam at short intervals. The beam then passes through a slit 16 in a plate 17 on to a specimen strip S and light scattered normal to the strip by reflection falls upon the cathode of a photo-cell 18. The strip S is mounted on a table T driven at constant speed so that the whole length of the strip is scanned by the beam 11. The beam 12 passes through an iris control 19 and then through an optical wedge 20 which is rotatably mounted. The beam 12 is then bent by a prism 21, is interrupted at short intervals by the shutter 15, passes through a slit 22 in the plate 17 and is reflected by a mirror 23 on to the cathode of the photo-cell 18. The intensity difference between the two beams acting alternately on the photo-cell 18 produces an alternating current, which is amplified and fed to a servomotor 27 causing it to rotate and drive the shaft 20a of the optical wedge 20 in a direction to reduce the intensity difference between the beams 11, 12 to zero and so stop the motor 27. The system is thus balanced continuously as the specimen moves and the degree of movement of the optical wedge 20 provides a measure of the colour density of the strip which may thereafter be recorded and integrated (see Group XIX). Apparatus for tracking a graph, Fig. 5 (not shown), comprises a light source whose beam tracks the graph and is then directed on to a pair of photodiodes or photocells 10, 11. Any deviation from the graph would cause a difference of light intensity to be registered to produce a signal, which, when amplified would drive a servomotor in a direction to bring the tracking arrangement back - on the graph to cancel the error signal.
