Title: Improvements in or relating to Projectile Fuzes.
IPC: F42C15/24
Filed: 1916-12-20
Abstract: 126,331. Rudge-Whitworth, Ltd., and Pountney, F. Dec. 20, 1916. Projectile fuses.-Relates to percussion fuses of the kind in which air pressure during flight of the projectile prevents the fuse from functioning prematurely. According to the invention, the construction is such that the air pressure is effective only during the initial high velocity period of the flight. In the fuse shown in Fig. 1, an inertia pellet a, having a light dome c secured thereto, is normally supported by clips h<2> projecting from a percussion-cap carrier h. A firing-pin e is carried by a shearing-pin f. On discharge, the pellet a sets back within the member h, ready to advance together with it when impact occurs. During the early stage of the flight of the projectile, however, the air pressure on the dome c is sufficient to prevent premature forward movement of the pellet and cap-carrier. The effect of a direct blow at any time is to crush the dome c and drive in the firing-pin c, breaking the pin /. In a modification of this construction, the firing- pin is divided, the front portion being attached to the dome c. Fig. 3 shows an example of constructions in which air-pressure acts directly upon the pellet a. In this and other modifications, a protective cover d<1> is provided, which is removed before the shell is placed in the gun. The directaction fuse shown in Fig. 5 comprises a member m carrying a percussion cap s on the inner face, the outer face having a groove into which the point e<5> of a striker e<4> protrudes. A shearing-pin f passes through a slot in the striker. The carrier m is normally locked in the position shown by an inertia detent n. On discharge of the projectile, the detent frees the carrier m, which tends to move under centrifugal force. The movement is at first prevented by the pressure exerted upon the carrier by the air, transmitted through the striker c<4>. When this pressure is sufficiently diminished, the carrier moves until the cap s is in line with the striker, whereupon the striker advances a short distance into a recess t<1> and locks the carrier in the armed position. Modifications of this construction are described in which a centrifugal member arranged in somewhat similar manner beneath a firing-pin, normally blocks an inertia pellet. One such construction is shown in Fig. 10, in which the striker w, resting upon a centrifugal bolt m<1> is attached to a diaphragm x, by which air pressure is transmitted.

Title: Improvements in or relating to regulating means for regulating transformers
IPC: H01H9/00
Filed: 1929-06-13
Abstract: 313,572. Siemens - Schuckertwerke Akt.-Ges. June 14, 1928, [Convention date]. Regulating transformers.-In transformers in which a pair of regulating switches associated with a tapped winding are operated in turn while the load current is diverted by means of a main switch, the contacts of the latter are so dimensioned and arranged that sections of the winding between tappings are not short-circuited in the switching operation, the load current circuit being completed through an arc gap of sufficient length that the voltage corresponding to one tapping section cannot maintain the arc. In the arrange. ment shown in Fig. 1, the voltage applied to the load circuit terminals 28, 29 by the secondary winding 1, is regulated by rotation of a spindle 8 operating in turn through gearing 24 - - 27 a pair of regulating switches 100, 200. Load current is diverted from each of these switches in turn prior to its movement by means of a main switch comprising fixed contacts 3, 7 and a movable contact 5. The latter is carried by a sleeve 4 freely mounted on the spindle 8 but connected therewith by a spring 22 adapted tn cause a rapid change-over from one contact position to the other. The contacts are so dimensioned as to leave a gap that is bridged over by an arc carrying the load current during the process of changing over, the gap being of sufficient length, however, that when the contact 5 reaches the next fixed contact, the voltage of the section of winding lying between the contacts engaged by the regulating switches 100, 200 is insufficient to maintain the arc, which is then extinguished. Fig. 3 shows a modification in which two pairs of regulating switches 100<a>, 100<b>, 200<a>, 200<b> are operated in due sequence through gearing 100, 200 from the main switch spindle 8. Each pair of regulating switches is associated with a potentiometer 31, 32 having a mid-point tapping connected to the fixed contacts of the main switch, so that voltage values lying intermediate those corresponding to the tapping points on the winding are available when the movable contact 5 of the main switch lies on contacts 34 or 36.
