Patent GB-147109-A (GB)
Abstract: 147,109. Zeiss, C., [Firm of]. March 2, 1918, [Convention date]. Sights.-Relates to apparatus for determining the data for firing at aircraft, of the kind embodying the triangle formed by the present and future lines of sight and the line of flight of the target, and consists in making the length of one of the unknown sides of the triangle a constant, or otherwise independent of the position of the target. In the triangle A B C, Fig. 1, A is the observer's position, B the present position of the target, and C the future position after a time T + t where T is the time of flight of the projectile and t a constant lost time. The present and future ranges are E, and E2 respectively, and the Length of B C is vg (T + t) where vg is the speed of the target. In the apparatus shown in Fig. 3, an arm e' representing A C is made of constant length, an arm m<3> set in direction by a telescope m<1> represents the side A B and the distance between the pivotal axes of these arms represents B C which is assumed to be horizontal. The arm e' travels over a vertical chart e<9> on which are marked height lines, fuse times in chain lines, trajectories in dotted lines, and curves in black lines dividing the chart into areas of equal values of the fraction (T+t)/E,. The lower end of the arm e' is mounted on a slide e<1> movable along a guide d' which can be set parallel to the line of flight of the target. The slide e' is adjusted by the rotation of a knob h<5> which is connected to a drum h<2> marked with curves corresponding to the areas defined by the black curves on the chart e<9>. The knob h<5> is rotated until a selected curve on the drum registers with a pointer g<4> which has previously been adjusted in accordance with the ground speed of the target. The future position of the target is indicated by the intersection of the top edge of the arm e' with the height line corresponding to the known height of the target. If this point does not lie in the area of the chart corresponding to the curve on the drum h<2> in contact with the pointer g<4> a further fine adjustment of the drum is necessary. A modification is described in which the length of B C is made dependent on the velocity vg of the target, the setting of the length of the sighting-arm being made by means of a cam plate; and other modifications are indicated in which, respectively, the length of B C is made constant, and the length of A C is made dependent on the velocity of the target. Specification 28398/09 is referred to.

A gear wheel 4 to be measured is rotated through a dog clutch 19 and spindle 3 by means of an electric motor M1, and a second spindle 3<SP>1</SP> is driven by a belt 9 in alternating directions so that a carriage 10 moves to and fro along a line r-r. This carriage 10, Fig. 1 carries a pivot 11 and draws a slide block 12 to and fro in the direction r-r as in Fig.2, and as the block 12 slidingly surrounds a bar 13 adjustably mounted on a carriage 17 then the sideways movement given by the belt 9 to the bar 13 is passed on to the carriage 17. A further carriage 7 is mounted on the carriage 17 so that rotation of the spindle 3 in one direction or the other causes a left or right displacement of the carriage 7 and a feeler 5 mounted thereon. The angle B of inclination of the bar 13 can be read by an optical device 16 and this angle determines the left to right movement of the feeler 5 which may correspond to the lead of the gear being checked. When angle B is >45 degrees the motion to shift carriage 17 is supplied by a motor M2. A motor M3 controls the movement of the feeler along its guide 18 and if the feeler is correctly angled by an optical arrangement 6 see also Fig. 3 (not shown) and motor M3 is actuated, then the flank of a gear tooth of 4 may be inspected. Carriage 14 may also be moved vertically in guide 20. In Fig.5 a block 26 fixed to the machine base forms a guide for a carriage 17 which is fixed to carriage 27 and operates driving bands 28 to rotate a belt 25 and a spindle 29a in alternate directions. The belt 25 moves a carriage 24 vertically and a slider 32 carries the feeler 5.

Patent GB-724223-A (GB)
Title: Improvements in and relating to phosphorescent materials
IPC: C09K11/58
Filed: 1952-06-18
Abstract: A phosphorescent material for use in the detection and measurement of thermal neutrons comprises a sintered mixture of an alkali borate and silver-activated zinc sulphide in approximately equal parts by weight.  The alkali borate can be sodium tetraborate or lithium tetraborate.  The material can be prepared by mixing the alkali borate with silver-activated zinc sulphide in approximately equal parts by weight and sintering the mixture by heating at a temperature in excess of the melting point of the borate but not greater than the melting point of the zinc sulphide.  The mixture can be sintered in air, an inert atmosphere or vacuo for approximately 10 to 20 minutes at a temperature between 800 DEG  C. and 1000 DEG  C.  After cooling, the material appears in large chunks which can be reduced in size to large granules having a greatest dimension of the order of one-eighth of an inch. Greater efficiencies per unit volume of the phosphor can be obtained by using sodium tetraborate enriched in the isotope B10 or lithium tetraborate enriched in the isotope B10 and/or Li6.  A thermal neutron flux can be detected by pulverizing the phosphorescent material and mixing it with oxygenated tetraethylene glycol dimethacrylate prepared in accordance with Specification 724,188.  The mixture is coated on a sheet of polymeric methyl methacrylate and air excluded therefrom to produce hardening.  The resulting article will produce light when exposed to a thermal neutron flux and can be utilized with any light sensitive devices or media for detecting neutrons, for example a photographic plate positioned adjacent the article. Specification 473,715, [Group III], also is referred to.
