Title: Improvements in Fuse Mechanism for Projectiles.
Inventor: MURPHY THOMAS
IPC: F42C5/00
Filed: 1917-08-08
Abstract: 128,616. Murphy, T., and Watson, C. E. Aug. 8, 1917. Torpedoes, locomotive; mines, marine. -Relates to fuses for projectiles intended for use against submerged targets, or for torpedoes, such fuses being of the kind comprising a rotatable vaned member which releases a piston, adapted on submergence to be moved by water-pressure so as to operate the firing - device. According to the invention, the piston c in the fuse normally prevents access of water to the fuse, by closing ports d, and is restrained in this position by a vaned bolt g, which is displaced by wind or water pressure during flight. The piston is moved by a spring e, as the bolt is screwed down by the action of the vanes i, until it abuts against ends j<1> of two pivoted two-armed resilient levers j. The opposite ends j<2> of these levers engage in a recess h<1> in a plug h. When the projectile has sunk to a predetermined depth, the water-pressure, acting through the piston c, bends the levers sufficiently for their ends j<2> to escape from the recess h<1>, whereupon projections j<4> strike and fire percussion caps k, so as to explode the projectile. The adjustment for depth may be effected by slightly varying the screwing in the plug h, or otherwise. The angularity of the vanes i may be adjusted to vary the period before the ports are opened.

Abstract: 712,405. Escapement mechanism. LANDIS & GYR. Ltd., and FREEMAN, D. R: May 15, 1952 [May 18, 1951], No. 11677/51. Class 80 (4) [Also in Group XXXVIII] Aperiodic impulses derived from a servomotor (not shown) responsive to trains of impulses derived from, e.g. plural wattmeters are applied to successively step a spur wheel 1 driving a sun wheel 2a of a differential gear 2 and on arrival of each impulse the planet wheel 2b drives through shaft 2c a disc 3 bearing pins 6, 6a, and a pinion 4 engaging a rack 14a traversing a sliding member 14, which moves a shaft 15a, carrying a friction wheel 15 axially of a rotary, turntable 13. At the same time pin 6 or 6a pivots lever 5 about its oscillatory supporting lever 35 to disengage hook 5a from pin 7a and release brake arm 7 from the constant speed disc 8, geared to rotate turntable 13. The latter rotates and drives friction wheel 15 at a speed proportional to the total number of arrived impulses stored in the differential so as to rotate through intermediate gearing a wheel 25 carrying a pin 26 interengageable with a projection 27a of an out-of-balance wheel 27. Simultaneously the wheel 25 rotates cam 34 to vertically oscillate lever 5 and its supporting lever 35 and also drives the second sun wheel 2d of the differential' 2 to restore the planet wheel towards its original position, from which it was deviated by the arriving impulses. The out-of-balance wheel is turned by wheel 25 and pin 26 until it reaches its unstable position and then completes a revolution under gravity to operate contacts 28 through cam 29 to emit one outgoing impulse, and simultaneously the oscillation of lever 5 enables hook 5a to re-engage pin 7a and brake the disc 8, since pin 6 or 6a has now disengaged the lever 5. Each successive aperiodic input impulse initiates a similar cycle, so that the contacts 28 re-transmit an output train of impulses numerically proportional to the input impulses at a rate proportional to the mean input rate, which may operate, e.g. a remote wattmeter.

Colour photography, screens, screen plates, and screen processes for.-Relates to screen prosceses for producing colour photographs on a paper or other support. A negative is first made through a three-coloured screen having a geometrical pattern. From this, according to one method, a diapositive is then made, and is used to make a contact print on a thin layer of gelatine, gum, &c. which is sensitized with bichromate, and is carried by a screen identical as regards pattern and colours with that through which the negative is made, the screen itself being carried by a thin transparent base. The exposed screen is washed and immersed in a solution of chloride of tin or other substance which decolours the dyes beneath the unhardened gelatine &c., and is finally gummed, with the transparent base uppermost, on to a paper or other support. In an alternative method, the gelatine or like layer is omitted from the second screen, and the screen is treated with anethol or other substance which facilitates the bleaching action of light upon the dyes. This screen is exposed to light beneath the original negative until the exposed colours are quite bleached, the remaining colours are fixed with benzol, and the base is gummed to the paper or like support. The screen used in the production of the final print may have a base of celluloid, of a transparent cellulose material permeable by liquids, or of tracing-paper (paper covered with a layer of wheat starch and gum). When a base of tracing-paper is employed, the screen may be printed with fatty inks. The screens may be coloured principally with aniline dyes, and the colours of the screen for the final print may be deeper in tone than those of the taking-screen. The final image may be transferred on to a base of glass, porcelain, &c.
