Patent GB-567213-A (GB)
Title: Improvements in portable photometers
IPC: G01J1/08
Filed: 1943-05-28
Abstract: 567,213. Photometers. GENERAL ELECTRIC CO., Ltd., and JESTY, L. C. May 28, 1943, No. 8579. [Class 97 (i)] [Also in Group XL] A photometer for measuring the brightness of a surface comprises a surface of luminescent material, an artificial source of radiation for exciting it, means for stopping the excitation at an observed time and means for enabling the decaying brightness of the luminescent surface to be compared with that of the surface under test, so that the moment at which equality of brightness occurs can be ascertained. The luminescent material is such, and it is excited to such an extent, that its brightness is a function only of the time which has elapsed since excitation, for all values of this time greater than a certain minimum. The time interval necessary to attain equality of brightness with that of the surface under test is therefore a measure of the brightness of the latter. The luminescent surface may be formed on a ring, through which the surface under test is observed, the ring being mounted in a box containing also an electric lamp for exciting it. Alternatively, two photo-electric cells may be used, each co-operating with one of the surfaces. The preparation of a suitable luminescent material consisting of a. zinc-cadmium sulphide matrix activated with copper is described. Specification 368,105 is referred to.
Patent GB-348291-A (GB)
Title: Improvements relating to the manufacture of glass sheets
IPC: C03B13/12
Filed: 1930-03-18
Abstract: 348,291. Making wire sheet glass. CHANCE BROS. & CO., Ltd. and FORSTER, A. L., Glasgow Glass Works, Firhill, Glasgow. March 18, 1930, No. 8637. [Class 56.] Relates to the manufacture of wire sheet glass and consists in providing means for feeding lengths of wire mesh to the sheet-making machine at a speed which is slightly less than that at which the sheets are formed, the feeding-mechanism being so arranged that the wire mesh moves with the same velocity as the glass sheet after it becomes engaged with the glass. The successive lengths of wire thus become separated by a convenient space which facilitates the subsequent cutting of the continuous glass sheet into lengths as described in Specification 339,764, [Class 56, Glass]. The wire mesh c is fed from a coil a by rollers b, d over a suitable horizontal support and between shearing-blades l or other suitable cutting-device, such as a flame. Other feedrollers i, j, k assist in carrying the wire to the rollers e, f, g of a machine for rolling molten glass 19 into a continuous sheet h. The mechanism for controlling automatically the operation of the cutting-device l comprises an endless horizontal chain q parallel with the run of the wire mesh and passing around end pulleys r. The chain carries a contact arm t which moves a pair of adjustable stops u, v carried by an horizontally movable bar w. The bar is connected to a lever x coaxial with another lever y, and the two levers are connected to one another by a spring 3. The lever y operates a clutch and reversing-device 2 through which the chain q is driven. The lever y also operates a bell-crank lever 8 which releases a valve 14 controlling a cylinder p that operates the cutting-device l. During the movement of the wire mesh, the arm t on the chain q approaches one of the stops u or v. As soon as it moves the stops it operates the levers x, y and causes the cutters t to make a rapid stroke and sever the wire mesh. The clutch 2 also reverses the direction of movement of the chain. The severed length of wire travels through a guide 18, and as soon as it becomes engaged with the molten glass 19, its speed is increased slightly, the increase being allowed by connecting the feed rollers i, j, k to their driving-shafts through free-wheel clutches. An electrically operated device may also be used for operating the cutting-device, the contact arm t then serving to control an electric circuit or circuits.

Abstract: 906,855. Making pistons; destructible cores; casting composite articles. SCHMIDT G.m.b.H., KARL. March 10, 1961 [March 11, 1960], No. 8912/61. Classes 83 (1), 83 (2) and 83 (4). A light metal piston with an annular cavity is made by providing a cylindrical casting of light metal, such as aluminium alloy, with an annular body cast therein, pressing the casting to the required shape and etching away the body. The annular body may be of iron or copper and is preferably evacuated and filled with paraffin during casting. The ratio of the volume of its wall section to the volume of its overall section is the same as that of the specific gravities of the light metal casting to the metal of the hollow body. During pressing the body is filled with colophony or zinc which is later melted out. The body is then etched away using nitric acid.

Title: A device for determining the speed and height of aeroplanes, or the speed and distance of land or sea craft relative to points on the ground, or for determining the speed, range or height of flying and other objectives
Filed: 1939-03-23
Abstract: 539,103. Measuring speed and distance by telescopic observation. SAVONA, J. S. E. March 23, 1939, No. 9122. [Classes 106 (iii) and 106 (iv)] [Also in Group XX] An apparatus for measuring the relative speed and distance between moving objects and the apparatus comprises a number of telescopes constrained by linkwork to move parallel with each other when swinging about pivots at their upper ends and also having an apertured belt driven at adjustable speed over their objectives. The rays from each telescope are directed each by mirrors 1b and 1g to a common image screen 1h. A pilot telescope is connected in the linkwork to enable the object to be maintained in the fields of telescopes 1. The speed of the apertured belt is adjusted until the image on screen 1h is steady in which case it will be seen that the rate of movement of the apertures over the telescope objective must be equal to or a multiple of the speed of the distant object. A speedometer on the driving motor of the belt may thus be graduated in terms of this speed. In order to determine the distance of the object a further speedometer is provided which measures the angular speed of the telescopes. A cam 10g driven by the ground speed indicator moves a logarithmic scale an amount according to the velocity V. A similar arrangement moves an R scale in accordance with the angular speed w of the telescopes. A further scale is moved according to the logarithm of the sine of the angle of elevation # of the object. As log V - log # + log sin # = log height of objective these scales furnish a ready means of calculating the height of the object as well as its range.
