Title: Improvements in or relating to length measurements by interferometer
IPC: G01B9/02
Filed: 1930-11-26
Abstract: 367,859. Optical interferometers. TWYMAN, F. and DOWELL, J. H., 24, Rochester Place, Camden Road, London. Nov. 26, 1930, No. 35614. [Class 97 (i).] In an interferometer apparatus for measuring in terms of wave lengths of light the length between two surfaces or between predetermined points thereon, the test object carrying the said points or surfaces, and a standard object carrying points or surfaces separated by a known length are adjusted so that the lengths to be compared are truly parallel, the distance in the longitudinal direction between the point or surface at one end of the test object and that at one end of the standard object is measured or adjusted to a measured value, which may be zero, by means of interference fringes, and the corresponding distance relating to the other ends is measured by similar means. The Figure shows a form of apparatus using two interferometer light-dividing systems, but forms are also described in which a single system only is used. In the form shown a collimator tube has at one end an illuminated apertured diaphragm 11 and at the other end a collimating lens 14 whereby parallel light is incident on the light-dividing plate 31, the second surface of which is lightly silvered so as to be partly reflecting. The light transmitted by the plate 31 passes through a compensating plate 32, identical as regards thickness and kind of glass with the plate 31, and falls on the surfaces 62, 72 of the standard object 61 and test object 71 by which it is reflected back along its own path. The light reflected by the plate 31 is reflected by a reference mirror 41 back to the plate. The returned separated beams are recombined at the silvered surface and enter a viewing telescope 85. A second system identical with that above described and comprising dividing and compensating plates 33, 34 and reference mirror 42 is arranged on the opposite sides of the test and standard objects 71, 61 so that light reflected from the surfaces 62, 73, and from the mirror 42, is received in a telescope 185. When the mirrors and the objects 61, 71 are properly adjusted and the instrument is illuminated by white light, an observer sees in the telescope 85 interference bands by means of which the surfaces 62, 72 can be adjusted so as to be in one and the same plane. The second interferometer system then enables the observer to see to what extent the surfaces 63, 73 deviate from being in the same plane. The method of adjusting the several parts of the apparatus is fully described in the Specification. The apparatus may be arranged to be illuminated by monochromatic light of any desired wave length, which may be obtained, for instance, by means of a constant deviation prism.

Abstract: 783,080. Magnetrons. M-O VALVE CO., Ltd. Dec. 9, 1955 [Dec. 9, 1954], No. 35736/54. Addition to 744,788. Class 39(1). In a multi-cavity magnetron with ring straps broken at specific points as described in the parent Specification, and designed for pulse operation, the end space geometry is adjusted so as to increase the amplitude of the #+1) spatial harmonic of the #-mode relative to that of the (#-1) mode at the beginning of a pulse. Transition from the (#+1) harmonic which has a lower threshold voltage than the (#-1) mode, to the fundamental #-mode then occurs more readily and stable #-mode operation is ensured. The end space geometry is adjusted by forming annular grooves 43, 44 in the walls of the end spaces. Coupling loops 11, 12 in the output cavity are oppositely orientated and are interconnected at their outer ends by an adjustable bridge 15 to form an output loop. The cathode 22 has enlarged ends each covered with a skin 24 of a metal of high thermal emissivity. Annular inserts 33, 34 of magnetic material in the cathode improve the uniformity of the magnetic field. The anode block 1 has cooling channels. Specification 783,079 is referred to.

Filed: 1934-12-14
Abstract: 450,402. Ammunition hoists. VICKERSARMSTRONGS, Ltd., and PEARSON, E. C., Broadway, Westminster. Dec. 14, 1934, No. 35957. [Class 92 (i)] [See also Group XXX] An endless - chain convoyer for hoisting ammunition, and of the kind in which the rounds are pushed from a platform A<3> into the path of lifting heads A<1> on the chain A, is provided with a shutter B in front of the loading opening, the shutter being automatically controlled by the lifting heads so as to open shortly before a head arrives at the position for picking up a round, thereby allowing an interval for loading, the complete closing of the shutter taking place after this interval, but before the head reaches the round to be lifted. Fig. 2 shows the position in which the shutter B has been closed, by the action of a descending head Al on a rail D just before the ascending head A<1> reaches the level of the loading platform A<3>. The rail D, in moving parallel to itself, rotates a shaft D<5> and thereby through torsion spring D', Fig. 3, and lever mechanism E<1>, Fl moves the shutter elements B to closed position. When the descending head leaves the lower end of the rail D, the shutter automatically opens under the influence of a spring d6 acting on the shaft D<5> and the round can be pushed on to a supporting pawl ready for raising by the head as it ascends. As the ascending head reaches the position shown in Fig. 2, the next descending head engages the rail D to effect closing of the shutter. Specifications 227,148 and 229,980, [both in Class 92 (i)], are referred to.

Abstract: 1320583 Texturing yarns TORAY INDUSTRIES INC 27 July 1970 [27 Aug 1969 2 Feb 1970] 36255/70 Headings D1F and D1W In the manufacture of texturised yarn possessing latent crimp, releasable, for example, after the yarn has been made into fabric, a bundle of yarn componental fibres is subjected to the steps of crimping by false-twisting and steam setting under pressure, dry heating at a temperature higher e.g. by 10-70‹C, than the steam-setting temperature while stretched to an extent less than e.g. 75-95% of the maximum crimp elongation, and, during such heating, pressing at least once against a heater surface so that the transverse cross-section of the fibres e.g. round or trilobal, is deformed by depression (particularly at locations of fibre cross-over) at random portions along the length thereof. False-twisting may be performed in two stages of opposite twisting and an additional dry heat treatment (during which fibres may fuse together) may be performed with increased stretch still less than the maximum crimp elongation and at a temperature higher e.g. 0-80‹C, than the steam setting temperature. As shown in Fig. 1, non-crimped yarn 1a of thermoplastic synthetic e.g. polyacrylic, polyamide or polyester, fibres is withdrawn from package 2 and advanced through guide 3 to a heater 7, wherein saturated steam circulates, by a feed roller assembly 4 and guide roller 6. Then the yarn is false-twisted by spindle 8, passes through guide rollers 9 and the crimped yarn 1b is withdrawn by roller 11 to be processed by a heat pressing apparatus 12, which includes a heated drum 13 and press rollers 14a, 14b before take-up by rollers 15 and winding into a package 17. The surface speeds of rollers 11 and 15 and the drum 13 are correlated to effect the stretching of the yarn and thus remove part of the evident crimp. In another heat pressing apparatus, Fig. 18, yarn 1b is advanced and wound several turns around and in contact with heated drum 13, roller 22, heated plates 23 coacting with press roller 24, and emerges as a modified crimp yarn 1c. Texturised yarns may be plied.

Abstract: 1519871 Moulding press E KUSTERS 11 Sept 1975 [31 Oct 1974] 37501/75 Heading B5A A press in which two pressure plates are forced towards one another by fluid operated means associated with a stop which determines the minimum spacing of the plates, includes a pressure relieving system which, when a counterpressure generated by the material being pressed causes the fluid operated means to leave the stop, causes the pressure plates to move apart to relieve the pressure on the material. The press may be of the double belt type having belts 1, 2 urged towards each other by pairs of opposed members 19, 20 acting on pressure plates 26, 27; each pair is interconnected by a hydraulic piston and cylinder 13 supplied at 33 by a pump 31 and via a valve 32 with pressure fluid to force the members 19, 20, towards each other. In the moulding position an annular web on each piston abuts one end of its cylinder and acts as a stop, and a chamber 54 thereby formed is supplied with relatively low pressure fluid via a control pressure system 50 including a pump 51, supply line 55 and a switch 57. When the force between the pressure plates exceeds a predetermined value the pistons are forced from their abutments thereby lowering the pressure in the line 55 causing the switch 57 to operate a valve 42 to enable high pressure fluid from a pump 41 to be fed through a line 45 to the upper ends of the cylinders to thereby separate the plates. The valve 32 is simultaneously actuated to enable fluid in the cylinder chambers 34 to be vented.
