Title: Projectile percussion fuze
IPC: F42C15/26
Filed: 1936-09-30
Abstract: 467,392. Projectile fuzes. MATERIELS ET ARMEMENTS MODERNES. Sept. 30, 1936, No. 26533. Convention date, Sept. 30, 1935. [Class 9 (i)] Relates to a combined direct and momentum action percussion fuze employing centrifugal safety members to separate the striker from the percussion cap. According to the invention, the striker rests in its normal position on eccentrically pivoted safety leaves which are held together and abutting a pin or stop by means of a spring carried on said stop in such a manner that, when the projectile leaves the muzzle of the gun, the leaves open under centrifugal force against the action of the spring and release spring loaded latches which hold the leaves in the open position and allow the striker to be driven back along the axis of the fuze to meet the percussion cap precipitated forward by inertia at the moment of impact. As shown, the fuze body 1 encloses the inertia pellet 2 which carries the relay pellet 3 and percussion cap 4 and is held in place by the spring 5. The safety mechanism, which is carried by the threaded washer- 6, comprises a pair of spring loaded latches 7 which normally bear against the under side of safety leaves 9, 10 pivoted at 11 and held against a pin 12 by a spring 13 carried in a slot in the pin. The direct action striker 14, which is guided by the element 15 and held in place by the spring 16, rests-on the upper surface of the leaves 9, 10 which separate it from the cap 4. In operation, the leaves 9, 10, after opening under the action of centrifugal force, are held in the open position by the latches 7, so that, on impact, the striker 14 and pellet 2 approach one another and the striker pierces the cap 4. The cap burns and ignites the relay pellet 3 which, being brought back very close to its abutment 17 by expansion of the spring 5, more readily fires the detonator 18.

Title: Improvements in or relating to explosive mines
IPC: F42B22/24

Abstract: 278,738. Soc. Anon. Fonderia del Pignone. Oct. 8, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Mines, marine.-Mines< >a, b, Fig. 4, connected together by a cable c, are provided with means for causing the mines to move, away from each other when laid to extend the cable c, which when encountered by a passing ship brings the mines against the sides of the ship and fires them there. A brake is provided to prevent an accidental tension of the cable, due to waves, from firing the mines, while allowing firing by a continued pull due to a passing ship. As shown in Fig. 7, a drum g is arranged at one end of the mine a, and a weight i hangs from a rope h wound on the drum g, which is connected to a screw propeller k either directly or through gearing 6, 7. The drum is normally locked by a pawl m kept in engagement with a toothed wheel l on the drum under the influence of a spring o; but when the mine is laid, an electromagnet p is energized from a battery q and pulls the pawl away from the toothed wheel, thereby releasing the drum and allowing the weight i to fall and drive the propeller k. One end of the other mine b is fitted with a similar device, and the other ends of the two mines are normally kept tied together against struts, as shown in Fig. 6. A spring plunger u on the mine a is attached to the cable c, which is wound on a drum z attached to a spring plunger u<1> on the mine b. A sleeve y also attached to the plunger u<1> is locked to the plunger u by a transverse pin 3. When the mines are dropped into the sea, a soluble plug 5 is dissolved away, and a spring 4 withdraws the pin 3. The released plungers u, u<1> close switches s, .s' which start the propellers in action, whereupon the cable c is paid out of the drum z and extended while the mines move away from each other.

Abstract: 748,746. Alternate use of channels. STANDARD TELEPHONES & CABLES, Ltd. Sept. 21, 1954, No. 27266/54. Class 40 (4). [Also in Group XL (c)] The Figure shows a rectifier switching circuit in which in dependence upon the polarity of a D.C. control voltage applied across terminals 7, 8 a transmission line connected to coaxial jack 5 is switched either to that connected across input 4 or input 6 respectively. When terminal 7 is positive with respect to terminal 8 rectifiers 11-14 and 23-26 are conductive and rectifiers 19-22 and 15-18 blocked so that input 4 is connected to output 5 and the path from input 6 is blocked. When terminal 8 is positive with respect to 7 input 6 is connected to output 5 and the path from input 4 is blocked. If transformers 1, 2, 3 are designed to give a correct impedance match to their respective transmission lines this will not be appreciably upset by the switching circuits 9 and 10. The transformers should preferably have a high step-up ratio as seen from the transmission lines so that a large difference is obtained in the attenuation of the switch circuits 9, 10 in the blocked and unblocked conditions.

Inventor: DAVIES WILLIAM
IPC: C22B1/20
Filed: 1957-09-02
Abstract: A process for treating an iron bearing oxidic material comprises for a bed of the material with a solid fuel and sintering it by drawing air, with or without a gaseous fuel, through the bed which is maintained at a temperature of 1100 DEG C. to 1500 DEG C., the amount of air and fuel being sufficient to reduce the greater part of the reducible metallic oxides to metal and the bed composition being such that the slag is fluid enough to envelope the liberated metal and prevent re-oxidation.  In order that the slag may be fluid, lime may be added to give a base/acid ratio of 1 : 1 to 5 : 1 and a boron of calcium oxide, may be added to stabilize any dicalcium silicate formed.  The material and fuel may be formed into agglomerates which may be coated with lime.
