Abstract: 1,066,583. Electron beam apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 21, 1964 [May 1, 1963], No. 17231/63. Heading H1D. In apparatus wherein a specimen is bombarded with an electron beam and the result analysed, secondary electrons scattered from the specimen S are trapped by a shield comprising thin plates extending from positions near the point of impact of the main beam on the specimen, in directions which are at a small angle with the trajectories of the secondary electrons. As shown, the shield may comprise concentric sheet metal cones or pyramids, or a spiral conical metal sheet, and is closed at its rear end by which it is insulatingly secured to beam focusing lens L2. The shield may be coated with beryllium or carbon to ensure low secondary emission. A grid G, similarly coated, and suitably biased, may be provided between the specimen and shield to remove low energy electrons. The specimen may be analysed by means of an X-ray detector, or by measuring the fraction of incident current accepted by the specimen. The specimen is mounted for rotary and transverse movement, and if its surface is inclined to the beam axis, the grid and shield may be asymmetric, Fig. 6 (not shown).

[Also in Divisions F2 and H2] Quick release of a vehicle accelerator pedal 20 causes a spring 25 to pull plates 5 and 6 towards a plate 7 mounting contact springs 15a, 15b, of a stop-light switch such that a knob 17 on plate 6 closes the contact springs 15a, 15b, an adjustable pressure spring 29 retarding movement of the plate 7 which is ultimately movable through a lost-motion pin-and-slot linkage 34, 35 by plate 5. Bellows 9 between plates 5, 6 has vents 14 gradually allowing air to escape until the pressure of the spring 15a pushes knob 17 away and opens the stop-light switch again. By this time the brake pedal has been applied, actuating a switch 52, so the stop-lights 51 remain lit until the brake pedal is released. If pedal 20 is released slowly the pressure of spring 15a on bellows 9 is sufficient to maintain the spring 15a, 15b apart due to the gradual emptying of the bellows.

Title: Data transmission means

Filed: 1965-04-28
Abstract: 1,074,368. Electric measuring systems. DATA RESOLVED TOOLS Pty. Ltd. April 28, 1965 [April 29, 1964], No. 17794/65. Heading G1N. [Also in Division G3] A solid model is scanned by a feeler gauge connected to synchros which measure the x, y, z co-ordinates in one 3-dimensional system and converts them via resolvers to co-ordinates in another system displaced from the measuring system by known angles. The values are compared with a drawing being traced, and are recorded on punched tape for use on a copying machine. The model (not shown) is mounted on a table 13 (Fig. I) angularly adjustable about two axes by jack-screws 14. A feeler gauge 27 is mounted on a carriage 26 above the model and is capable of movement in the x, y, z directions. Movement in the x direction is transferred by a perforated steel tape 31 coupled to the carriage 26 to a resolver 43 (Fig. 7) which is angularly displaced by a required angle A, so that the rotations of the output shafts 44, 45 are x sin A and x cos A. Movement in the y direction is transferred by strip 35 to a resolver 43 to give the values of y sin A and y cos A. The angle A is the angular displacement between dimensional systems about the Z axis, and is fed into a synchro 61 which energizes motors 62, 63 driving the resolvers 43. Each of the component outputs is measured electrically by synchros 49-54 in coarse and fine units. Movement in the z direction is fed to coarse and fine synchros 59, 58 via a rack 37 and pinion 38. Thus, if the instantaneous dimensions sensed by the feeler 27 are x 1 , y 1 , z 1 , these are converted, in coarse and fine values, to (x, cos A + y 1  sin A), (- x, sin A + y 1  cos A), z representing the corresponding dimension z, when the system is rotated through an angle A about the Z axis. The dimensions of the model are to be recorded by two graphs representing the x, y and x, z relationships, traced out by two pencils 74 (Fig. 1) on a chart 76. The co-ordinates of each pencil are fed to resolvers 72, 73. An angle B, being the angular displacement between the dimensional systems about the Y axis is fed into a synchro 71 which energizes motors to drive the resolvers 72, 73. Hence, if the instantaneous dimensions sensed by the pencils 74 are x 0 , y 0 , z 0  these are converted in coarse and fine values, to (x 0  cos B - z 0  sin B), y 0 , (x 0  sin B + z 0  cos B) and these should agree with the converted dimensions from the model. These signals are compared electrically and any difference is fed via amplifiers 99 to motors 86, 87, 88 which correct the position of pencils 74. The co-ordinates of the pencils are also fed to visual read-out means 110, and a punched tape recorder 111, 112.
