Title: Method of growing single crystals
IPC: C30B11/00
Filed: 1973-06-26
Abstract: 1414087 Monocrystalline rods PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd (Philips Gloeilampenfabrieken NV) 26 June 1973 30178/73 Heading B1S Elongated rod-like single crystals are made by passing a solidification front through a molten, or partially molten in the case of zone melting, elongated body wherein the heating is effected by individually energisable heating elements positioned transversally asymmetric relative to the elongated body and the heating element is at least partly trough shaped to ensure uniform heating of the lower side and upright sides of the longitudinal part of the body. If desired another heating element may be present. Both heating elements may operate independently. The method may be used for forming single crystals of III-V type compounds including arsenic-containing compounds and the starting material prior to melting may be in the form of lumps or loose powder or the material of the single crystal may be formed in situ by adding one of the components e.g. arsenic in the gaseous phase to a melt of the other ingredient of the crystal-forming composition. A solvent and/or dopant may also be present. A monocrystalline rod of gallium arsenide is exemplified. As shown in the Figures a furnace jacket 1 contains trough shaped heating elements 2 comprising heaters 3. The enclosure in the form of a chamber 6 contains a body 4 of starting material in a vessel 5. The trough shaped screens 7 support the chamber and aid uniform distribution of heat. The furnace is closed by a cover 9 comprising a heating element 11 and being seated on observation window rods 12. The heater 3 is shown in Fig. 3 in the form of a resistance heater constructed of half turns connected in series. The half turns 21 have vertical extensions 22 and 23 and the ends 24 of the heater serve for connection purposes.

Abstract: 1,271,011. Firearms; projectiles. P. A. JONEAUX, P. E. F. TELLIE, and M. MANERO. 19 June, 1969 [19 June, 1968], No. 31191/69. Headings F3A and F3C. A firearm comprises a cannon tube A closed at one end and having a rifled bore, a carrier tube B slidably receiving the tube A and a trigger mechanism C mounted on the carrier tube B the cannon tube having a static firing position at the exit end of the carrier tube so that, on firing a projectile the cannon tube will move rearwardly in the carrier tube. In the construction shown the bore of tube A is stepped, the forward, larger diameter part A, receiving the warhead of a projectile P and the rear smaller diameter part A 2  which is the rifled part of the tube A receiving the propulsive device D of the projectile P. The tube A at its closed end carries a spring held firing pin 2 and a fuse bearing nipple 5, the nipple 5 having a flexible arming cable 6 attached thereto. The trigger mechanism C includes a spring loaded slidable seer 25 which, in the mechanism cocked position holds a striker 29 against its spring loading (Fig. 6, not shown). On actuation of the seer 25 by a trigger button 23, the striker pivots to engage the firing pin 2 and at the same time engages a safety catch 27 which normally holds the tube A in its forward firing position to releaes the tube A for rearward movement in the tube B under the action of the propellent gases. A front stop 34 is provided at the forward end of the tube B to limit forward movement of the tube A. For carrying the firearm-projectile combination the tube A is retracted to the rear of tube B and held therein by a key which projects through the tube B and is held in position by a piece of adhesive tape (Fig. 3, not shown). A screen 16 is pivoted to the forward end of the tube B and acts as a closure cap for the firearm during transportation. The propulsive device D of the projectile comprises a partly rifled girdle 10 surrounding a housing 8 which contains blocks of propulsive powder 11, a detonator 12 and an ignition charge 14. The housing 8 carries a plurality of nozzles the axes of which converge towards the centre of gravity of the projectile. The inner periphary of the housing 8 is closed by a thin light alloy tube 9 and is fitted thereto by crimping. The tube is also crimped to the warhead of the projectile and thus forms the connecting between the propulsive device D and the warhead.
