Abstract: 901,319. Optical gauging apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 31, 1960 [April 8, 1959], No. 11891/59. Class 106 (2). Optical apparatus for gauging the distance between two points of an object 15 comprises two units 6, 7 (each consisting of a rhomboidal prism to one face of which is cemented a triangular prism, the interface being partially reflecting); means 3 for forming two normally coincident images of the object, means for moving the units 6, 7 relatively to one another and means for measuring the relative movement necessary to cause the images of end points of a diameter of the object to coincide. The units 6, 7 are relatively rotatable about an axis 14, preferably by two micrometer screws geared together, and the images are observed through an eyepiece 3, the whole device being fitted to the draw tube 2 of a microscope. Coincident images of the object 15 are first observed and the prisms are then rotated until opposite edges of the images are superimposed. The rotation required, measured by the micrometer screws, gives a measure of the diameter of the object 15. In addition, plane-parallel glass plates 16, 17 may be used, these being rotatable about a horizontal axis in the plane of the paper. This is particularly useful if the device is used as a comparator, the only measurements then required being the amount of rotation of the plates 16, 17.

Title: An electromagnetic indicator
Inventor: LANG ELLIOT RICHARD
IPC: G08B5/30
Filed: 1966-03-18
Abstract: 1,080,458. Selective signalling. PATENT BUTTON CO. March 18, 1966, No. 11908/66. Heading G4H. An indicator of the type in which a numeral drum, Fig. 2, is selectively positioned by energizing one of a plurality of stator coils, is characterized in that the numeral drum is attached to a magnet 66, Fig. 5, so proportioned that when one end is adjacent a stator coil the other end is between two coils. This avoids the zero initial torque that would be applied to the magnet when a 180-degree rotation is called for were the rotor magnet straight. To increase the stability of equilibrium of the rotor its centre of rotation is off-set with respect to the centre of the magnet. By connecting the stator coils so that a positive input pulse causes a pattern of alternately north and south poles and a negative pulse a pattern of alternately south and north holes around the stator, the device can be used to count alternately positive and negative input pulses.
