Patent GB-595101-A (GB)
Title: A method of coating a surface with quartz
IPC: C03C17/245
Filed: 1945-06-22
Abstract: A surface is coated with quartz by covering the quartz with a metal, disposing the metal-coated quartz within an electrically heated filament in a high vacuum to heat the quartz to a high temperature and to evaporate said quartz and depositing the quartz on a support surface, the said metal having a melting point lower than the temperature to which the quartz is heated to effect its evaporation. Specified metals are aluminium, magnesium, calcium and barium, and a temperature of above 1,500 DEG C. is necessary to evaporate the quartz.  Referring to the drawings, Fig. 1 shows the apparatus for coating the quartz with metal.  Inside a bell-jar 11 resting on a base 10 is an electrically energised heating filament 13 supporting pieces of metal, while on the base rests pieces of quartz 16.  On energising the filament the metal particles evaporate and are deposited on to the quartz.  Fig. 8 shows a similar apparatus used for thermal evaporation of the metal-coated quartz shown here as a bar 18 surrounded by filament 20.  The surface to be coated 27 is supported on a base 26.  The chamber is evacuated (means not shown) and the filament energised when surface 27 (e.g., glass) is coated with quartz.  Fig. 10 shows a modification in which the bell jar 45 contains several coiled electrically heated tungsten filaments 20 supporting uncoated quartz rods 180 and filaments 20a supporting pieces of aluminium (or silver) 46, while a glass plate 127 is also supported <PICT:0595101/III/1> <PICT:0595101/III/2> <PICT:0595101/III/3> <PICT:0595101/III/4> inside the jar.  The jar is evacuated and the filaments carrying the aluminium (silver) energised, when the metal evaporates and is deposited both on the glass surface and on the quartz.  Then the filaments carrying the quartz are energised thus giving a glass surface coated with aluminium (silver) and then with quartz. Instead of using metal-coated quartz, the quartz in the form of a round bar 40, Fig. 7, may be provided with a close wrapping of a relatively thin wire 41 of the metal and used in the same manner.

IPC: F41A27/06
Filed: 1960-05-06
Abstract: 1,099,651. Ordnance mounting. MINISTRY OF DEFENCE. May 2, 1961 [May 6, 1960], No. 16207/60. Heading F3C. A gun control apparatus is provided, in addition to the normal elevating and transversing gear, with a mechanism for applying to the gun barrel small elevation and traverse movements relative to its cradle. The barrel 1 is carried in a cradle 2 by a pair of cylindrical bearings 3 and 4 in which the gun can recoil. The front bearing 4 has a bore with a minimum diameter at its centre so that the gun can pivot relative to the bearing, and the rear bearing 3 is hinged to the cradle 2 at its lowest point. The mechanism for applying the small elevation and traverse movements consists of two sets of pistons whose axes are perpendicular to each other. The first set (Fig. 2, not shown) comprises four pistons arranged in two coaxial pairs carried in cylinders which form part of the cradle 2. Each piston bears on a roller carried by an axle mounted longitudinally in the bearings 3. Extension or retraction of the upper pistons of each pair and retraction or extension of the lower pistons causes the bearings to move parallel to the piston axes to elevate or depress the gun barrel 1. The second set (Fig. 3, not shown) comprises two horizontal pistons so that extension or retraction of one piston with a similar retraction or extension of the opposed piston moves the bearing 3 in traverse by rotation about the hinge. The pistons are hydraulically operated through pipes 25. To avoid undesirable movement of the bearing 3, a locking wedge 33 is provided for retaining the bearing in its central position. The pressure pad 47 maintains the gun against the upper part of the bearing during aiming, but still allows a small amount of play between the gun and the bearing to enable the gun to recoil freely in the bearing.
