IPC: F42C15/24
Filed: 1916-01-25
Abstract: 124,483. Petch, A. F., (Struble, G., and Lukens, W.). Jan. 25, 1916. Projectile fuses. -Relates to percussion fuses of the kind in which a movable fixing- member is disposed approximately at right-angles to the axis of the projectile, and is normally locked by a bolt in line with, or parallel to, the axis. According to this invention, in the flash passage through the firing member, adja. cent to the locking-bolt, an obturator is provided which prevents a flash caused by premature ignition of the cap from reaching the explosive charge, but, when the locking-bolt is withdrawn on impact, allows a flash to pass. In the construction shown, a spring-pressed striker 21, having a firing-pin 23, lies within a transverse hole 18 in the body of the fuse, and is normally held in the retracted position by the tail 17 of an axiallydisposed spring-controlled bolt 15. The tail, en. gaging in a hole in the striker, normally closes a passage 30, which, together with a chamber 26 and passages 24, form the flash-conduit in the striker. At the end of the chamber 26 adjacent to the tail 17 of the bolt are two disks 32, 33 of tinfoil and brass, or the equivalent, which co-operate with the tail of the bolt to form an obturator, so that if the cap 20 is accidentally fired when the parts are in the position shown, the flash is confined to the chamber 26. Beneath the end of the bolt is a hole 34, separated from a powder-pellet 35 in the central flash-passage by a disk of shellac-coated muslin. On impact, the bolt 15 moves forward by inertia, releasing the striker 21 and uncovering the passage 30. The striker is at once thrust forward by its spring 28, firing the cap 20, and the disks 32, 33 yield to the flash.

Title: Improvements in or relating to method for preparing metal salt solutions
Inventor: HEALY THOMAS VICTOR
IPC: C01G43/00
Filed: 1957-01-15
Abstract: Aqueous solutions of metal nitrates are converted to a different mineral acid salt of the metal by boiling the nitrate solution with formaldehyde and the mineral acid required.  The initial nitrate solution may also contain nitric acid and the formaldehyde used must be sufficient to react with all the nitrate ions and the nitric acid present in the solution.  The chlorides, sulphates and perchlorates of metals such as iron, uranium, lithium and sodium may be so prepared.  According to an example a solution of uranyl nitrate in dilute nitric acid was treated with dilute sulphuric acid chemically equivalent to the uranyl nitrate and the solution was boiled with sufficient formaldehyde to destroy all the nitric acid present and react with all the nitrate ions present.  Substantially pure uranyl sulphate was produced. Specifications 761,252 and 784,609 are referred to.
