Title: Improvements in percussive fuze devices for projectiles
IPC: F42C1/02
Filed: 1938-12-12
Abstract: 522,484. Projectile fuzes. REMONDY, L. E Dec. 12, 1938, No. 36126. Convention date, Dec. 20. 1937. [Class 9 (i)]  A direct-action projectile fuze comprises a member forming a closing member for the fuze body and sensitive to the action of even a very slight pressure, a light striker sliding freely in an axial channel in the fuze body and finally a fixed percussion cap simply protected by its own end or by an equivalent baffle against the light shocks or rubbing of the striker, the latter being of a length less than the minimum distance existing between said percussion cap and said front member and the ignition being effected owing to the fact that, upon impact, the shock or the pressure exerted on the front member and transmitted thereby to the striker nullifies the momentum of the latter, or even changes the direction thereof, which enables the striker to encounter the percussion cap which, being connected to the projectile, continues its movement therewith. As shown in Fig. 1, the cylindrical striker 1 is free to move in the cylindrical recess 5a between the percussion cap 2 and a diaphragm 4 closing the front of the fuze and behind which is a cavity 5. The fulminating composition of the cap 2 is normally protected from the impact of the striker either by the end 6 of the cap if the latter is placed as shown with its orifice directed towards the interior of the fuze, or by a light plate of suitable thickness and strength. The fuze body 3 is formed with an air escape passage 7 closed by a light air-tight plug 8. In operation, on discharge of the projectile, the striker is ,applied without violent shock against the percussion cap, as shown. As soon as the projectile leaves the gunbarrel, however, the striker creeps forward until its front end bears against the diaphragm 4 so that when, on impact, the diaphragm is deformed, the striker is driven violently rearwards against the percussion cap and causes the ignition thereof. The air forced back by the diaphragm and striker escapes through the passage 7. If desired,' the striker may be of truncated conical form, Fig. 4 (not shown), or may have an enlarged front portion, Fig. 5 (not shown). Fig. 6 shows a modification in which a safety washer 9, adapted to break up very rapidly either under the action of centrifugal force or of heating due to the friction of the air is provided between the striker 1 and diaphragm 4. According to modifications, thediaphragm 4 may be replaced by a capsule 13, which, as shown in Fig. 9, is normally held in position by a pin 14 and is provided in its' upper part with an air-tight joint 15, or, as shown in Fig. 10, is maintained in an advanced position by a light spring 18, the forward movement of the striker being limited by a collar 19 thereon adapted to be arrested by flange 21.

Filed: 1958-11-14
Abstract: Pigments contain titanium dioxide in its rutile modification as the basic component and, as addition components, on the one hand tungsten oxide or a mixture of tungsten oxide and the oxide of antimony, bismuth, vanadium and/or uranium, and on the other hand the oxide of lithium, magnesium, zinc, divalent manganese, iron, cobalt, nickel or copper, aluminium, gallium, copper, trivalent titanium, chromium, manganese and/or iron or mixtures of two or more of these oxides, the amounts of said additional components used being such that the total average statistical valency of the cations is about four.  Mixtures of the components may be converted into the mixed crystals at elevated temperatures particularly at red heat.  Instead of the oxide components there can be used compounds of the various metals which are converted by heating into the oxides.  Thus for example instead of titanium dioxide, titanium hydroxide can be used; and instead of the oxides of manganese or zinc there can be used the hydroxides, carbonates, acetates, nitrates or formates.  Small amounts of a fluidizing agent such as lithium or sodium fluoride may also be added.  In a typical example the oxide components are mixed together, calcined for half an hour at 800 DEG C., and then pulverized and calcined for a further half hour at 1000 DEG C.  Numerous examples using various mixtures of oxides are given.
