Patent GB-1113207-A (GB)
Title: A measuring device which enables correction factors to be incorporated in measurements
IPC: G01B3/18
Filed: 1965-09-13
Abstract: 1,113,207. Micrometers. A. L. WOOLDRIDGE. Sept. 13, 1966 [Sept. 13, 1965], No. 39076/65. Heading G1M. Measuring apparatus for incorporating a compensating factor into length measurements comprises a frame 11, a threaded portion 13 mating with the threaded portion 15 of a thimble 17, such that rotation of the thimble 17 moves axially a barrel 19 and associated aligning tube 21 coupled thereto by a nut 30. A key 22 slides in slot 23 of frame 11 to prevent rotation of tube 21 and barrel 19 but permit axial movement thereof. A spindle 25 extends through the aligning tube 21 to provide at one end a work engaging surface 27, the key 22 engaging a helix 29 on spindle 25 such that the spindle 25 rotates less than one revolution during its axial range of movement. To provide the compensating factor a cam 37 is mounted at the other end of spindle 25 a ball 35 being constrained between helical groove 36 on the curved surface 34 of cam 37 and the diametrical slot 33 of a retainer 41. Thus rotation of the cam 37 relative to barrel 19 adjusts radially the position of ball 35 to provide a measurement correction. In a modification, the cam surface 34 has a flat portion so that the apparatus may operate as a conventional micrometer.

Title: Manufacture of metal matrices having surface patterns thereon
Inventor: HOOLAHAN MICHAEL JOHN
IPC: B41C3/00
Filed: 1964-09-25
Abstract: 1,049,297. Making patterned metal matrices. MODERN ENGRAVING & MACHINE CO. Sept. 25, 1964, No. 39098/64. Heading B3A. In a method of making a metal matrix a piece of burlap, for example, is sprayed with a non-eutectic alloy of bismuth, lead, tin and cadmium which expands on solidifying. The patterned side of the metal negative is sprayed, preferably with vinyl plastisol, which cures at a relatively low temperature and the plastic positive is then formed into a sleeve 19 with the pattern inside. A steel plating tube 20 is centrifugally coated with wax 24 and the wax and sleeve 19 are coated with a pressuresensitive adhesive 25. The sleeve is then placed on metal rods 26, 28 and inserted in the tube 20 with its jointing seam 17 resting on the wax. The rods are rotated in opposite directions while a roller 30 is swung in a progressively larger arc to both sides of the seam 17. When the roller begins to touch the rods 26, 28, the tube is turned 180 degrees and the non-adhered arc of the sleeve is gradually rolled down from its outer edges. The interior of the tube is sprayed with silver nitrate by the use of nitrogen. The tube 20 is stood on a sealing pad 40 of a stand 38 (Fig. 6, not shown), and concentrically of a plating fluid dispenser 42 and an anode 46. The plating solution is forced upwards from the dispenser 42 and deposited on the sleeve 19 to form a shell. The plating may comprise copper, nickel, iron, gold, silver, brass, chromium or any combination thereof. The sleeve-shell combination is removed from the tube 20 by melting the wax and the sleeve 19 is removed from the shell, which is preferably of copper. The inside of the shell is tinned before being soldered to a tinned steel cylinder and finally journals on the cylinder are machined concentric with the patterned peripheral surface, which may be chromium plated after machining.

Title: Vibration energy transfer devices and methods for testing
IPC: G01H1/00
Filed: 1962-10-18
Abstract: 1,009,267. Vibration testing. BOEING CO. Oct.18, 1962 [Aug.13, 1962], No. 39499/62. Heading G1S [Also in Division H4] In an energy transfer system or testing device a test specimen T supported at its nodes by members 60 is vibrated e.g. by an audio speaker 80 with a horn 86, at its resonant frequency. Vibrations from the test specimen T are imparted to a line element L which is in point contact with the specimen T and has a low contact pressure. The tension in the element L is adjustable by means of weights 22 and is chosen so that the resonant frequency of the element L is not close to that specimen T. The element L is mounted on pulleys 10, 12 and padding members 16 are provided so that only travelling waves are produced in the element L. Vibrations of the element L are detected by a piezoelectric crystal 40. The "Q" value of a material i.e. the reciprocal of its damping qualities due to internal friction may be used as a measure of various characteristics of a material e.g. strength and fatigue. The Q value can be found by measuring the number of vibrations above a given amplitude transmitted to the element L after the audio speaker 80 has been switched off. This is determined by a digital counter 124 controlled from the piezoelectric crystal 40 by an electric circuit (Fig. 5). The position of the line element L is adjusted to give the maximum value of Q. In other embodiments non-symmetrical test specimens are used. The specimen can be vibrated in a flexural or torsional mode. An additional line element may be used instead of the audio speaker 80 as the exciting means.

Abstract: 1442627 Target-seeking missiles MESSERSCHMITT - BOLKOW - BLOHM GmbH 28 Aug 1973 [5 Sept 1972] 40433/73 Heading F3A [Also in Divisions H3-H5 and G3]  If a self propelled, active on passive guided missile has a fixed acquisition field of view 3 or 6, Fig. 1 (e.g. antenna lobes) targets on paths 4 or 5 will be respectively missed. To overcome this, the angle α of the field of view is increased as the missile nears the target, according to the equation: (C#=αmin.Rmax. R MT =missile to target distance. ¢###2). Fig. 2 shows plots of the equation for α=À5, 1, 1À5 and 2 together with five possible evasive paths of the target, 11, 12, 13, 14, 15. It is seen for example that the angle variation according to α=C#.R MT -<SP>.5</SP>, will only acquire a target on path 11 and then only at large values of R MT , whereas with the angle variation of α=C#.R MT <SP>-2</SP> only the path 15 is totally non-acquired. The angle variation may be according to a stepped approximation 16 to the equation. Once the target has been acquired, the angle α can be reduced to increase tracking accuracy. To maintain the stability of the guidance loop however, the angle α, after acquisition can continue according to the equation.
