Title: Outline following apparatus
Inventor: MOSS BRIAN YOXALL
IPC: B23Q35/128
Filed: 1968-05-09
Abstract: 1,248,586. Template followers. MORFAX Ltd. May 2, 1969 [May 9, 1968], No.22027/68. Heading G3N. [Also in Division G1] In a photo-electric line (outline, template or pattern) follower, besides the main reciprocably mounted photo-sensitive device for providing the line following function, an additional photo-electric device is mounted on the reciprocating mount and is arranged to sense lateral markings at one side of the line being followed so as to provide an additional control function e.g. slowing down or stopping of the follower. The mount 42 carrying the main photo-resistor 101 and additional photo-resistor 103 which is oriented at right angles to the photo-resistor 101, is attached to a block 49 which is moved by eccentric pin 48. Since the block 49 has an arm 51 which projects through the forked part of downwardly projecting member 52, the block 49 reciprocates in such a way that arm 51 reciprocates linearly while the opposite side of block 49, and therefore mounts 42, oscillates in an ellipse. Photo-resistors 101 and 102 therefore execute elliptical scans across the line D, photo-resistor 102 serving as a forward-seeking element, to aid the main following function. For the main line following operation, the output of photo-resistor 101 is amplified, filtered of components at twice the oscillation frequency and fed to servo-amplifier (SA) Fig.1 (not shown) to drive motor M so as to rotate the follower head as a whole to align the reciprocating arm 51 with the line. Rotation of the head is sensed by potentiometer 59 which controls the X and Y drive motors. Photo-resistor 102 operates only to respond to sharp changes in direction of the line and in these cases opens a relay to introduce a slow-down resistor (SR) Fig. (not shown) into the potentiometer 59 supply. The laterally mounted photo-resistor 103 may provide a number of subsidiary functions and responds to marks such as 43, Fig.3, to slow down, or stop the follower (e.g. by short circuiting the supply to the potentiometer 59) via a relay. Alternatively it may switch a solid state switch to produce a reverse drive to prevent over-run. A further additional photo-resistor may be provided on the other side of the mount 42 to respond to lateral marks on the other side of the line. These marks may be coloured and the additional photo-resistors be provided with filters. The lower part of the head carries a lens 41 mounted in a transversely movable slide 38 and a marker pencil beam producing light source.

Title: Coupling means for the detachable assembly of component parts of apparatus, especially photographic cameras
IPC: G03B3/02
Filed: 1957-07-16
Abstract: 851,451. Photographic cameras; lens mounts. AGFA A. G. July 16, 1957 [Sept. 14, 1956], No. 22567/57. Classes 97(1) and 98(1) [Also in Group XXV] In coupling means for the detachable assembly of parts of apparatus, wherein one part has a ring resilient in its own plane, which engages a conical surface on a second part which is thereby caused to seat on the first part, the angle between the generator of the conical surface and the plane of the ring being greater than zero but smaller than the angle at which a force pulling the first component away from the second will provide a component acting on the ring in excess of the friction between the ring and the conical surface, and between the ring and one part; and a release member is movable to deform the ring to allow a separation of the parts. As shown in Fig. 1 and 2, a ring 3 is secured to the camera body 1 by means of screws 2. The gapped resilient ring 7 is located between the ring 3 and a second ring 5 which is trapped between the ring 3 and the mount 1. Spring ring 7 engages a conical surface 4a formed on the objective mount 4. The angle of the generator of the conical surface 4a with the plane of the ring is made sufficiently small that if the objective mount is pulled axially, the friction between ring 7 and the conical surface 4a and the surface of the ring 3 prevents the ring from being moved outwards by camming action on the conical surface 4a, the ring 7, therefore, being strongly resilient. To release the objective the ring 7 may be opened by action of a slidable wedge 9. To reduce local wear on the ring, the parts 7c, where great pressure would otherwise be exerted on the conical surface 4a, are cut away. A further conical surface 4c is formed on the objective mount, with the angle between its generator and the plane of the ring 7 much greater than the maximum angle of the conical surface 4a, so that the objective may be pressed into place. To locate the objective against rotation, a resilient tongue 5b is formed on the ring 5. On insertion of the objective mount, the tongue will in general be depressed, but on rotation it will snap into a corresponding recess on the objective mount. In modifications: (1) the objective mount is formed with pins which bear on recesses mounted in the camera body; (2) the ring 3 has an oblique surface on which the spring ring tends to climb when the objective mount is rotated.

Abstract: 688,977. Automatic gramophones. OAK MANUFACTURING CO. Sept. 14, 1950 [Sept. 14, 1949], No. 22626/50. Class 40 (ii). A tone arm 82 particularly for use in an automatic gramophone of the kind described in Specification 688,972, is pivotally mounted on a horizontal pin 76. The pin passes through slots 67, 68 in a mounting 55 clamped to a sleeve 46 by a bolt 62. Springs 78 or one central spring retain the pin at one end of the slots and allow the tone arm to yield in a horizontal plane relatively to its mounting. One end of the pin passes through a hole 83 in the tone arm while the other end is secured in a plate 85 adjustably mounted on the arm, to allow the arm to be adjusted relatively to the mounting. The tone arm is moved across the record by rotation of the sleeve 46. To lift the tone arm from the record, a pin 95 in the sleeve 46 is raised by a cam and it lifts one end of a lever 72 pivoted on the mounting 55. The other end 88 of the lever moves down against an adjustable stop 90 to force the end of the tone arm down and raise the other end. The stop 90 also acts as counterweight. A spring may be placed between the mounting and the end 88 of the lever to reduce the needle pressure. A general outline of the driving mechanism is described with reference to Fig. 1 (not shown).

Filed: 1974-05-22
Abstract: 1452231 Classifying nucleic acid containing particles BLOCK ENG Inc 22 May 1974 [2 July 1973] 22790/74 Heading G1A Particles containing nucleic acid and treated with a fluorescent dye are classified in a fluid in apparatus which illuminates the specimen with excitation radiation and views the fluorescence and which spatially filters at least one of the illuminating and fluorescent radiation. Classification by size is obtained by analyzing the fluorescent radiation for modulation at different low frequencies due to Brownian movement. By using suitable dyes and detectors responsive to a single frequency RNA and DNA containing particles e.g. viruses can be distinguished. The percentage of DNA and the particle shapes can be derived from polarization measurements on scattered radiation.  As shown, light from source 12 which may be a laser passes through wavelength filter 14 and spatial filter 18 which may comprise a grating, grid or annuli. The filter is focused on to sample 20 by optics 16. The fluorescent and transmitted radiation passes through optics 22 and is separated by splitter 24 on to detectors 26, 28, 30 which may be frequency sensitive or have associated filters 32, 34. Detector 30 has a mask 48 to block out direct light and the mask may be associated with a polarization detector. The detected signals are amplified, analyzed by frequency analyzers 42- 46 and recorded on strip charts or fed to a computer.
