Title: Improvements in or relating to electrical counting apparatus
Inventor: SNELLING ALEC ROY
IPC: H03K23/82
Filed: 1952-08-28
Abstract: 735,942. Electronic counting apparatus. CINEMA-TELEVISION, Ltd. Aug. 28, 1953 [Aug. 28, 1952], No. 21635/52. Class 106 (1). In an electric counting apparatus comprising a chain of four binary counter stages having feed-back paths to produce an effective scale of ten, points in each stage which suffer predetermined voltage excursions when the stages are operated, are connected through resistors to one terminal of a current meter whose other terminal is maintained at a fixed potential, whereby the indication of the meter corresponds to the number counted by the chain. Negativegoing pulses entering at a terminal A step the binary chain of trigger pairs 1, 2 . . . in the usual way until the eighth pulse reverses the trigger 4. This causes negative pulses to be fed back to stages 2 and 3, reversing them again so that the chain now represents a binary count of 14. Thus two more input pulses complete a cycle and bring the chain back to its initial condition after ten input pulses. A " carry " pulse for transfer to the next decade appears at a terminal B. Resistors 14, 15, 16, 17 connecting the R.H. anodes of each trigger pair with a centre-zero meter 18 are selected to pass currents to the meter in the ratio 1 : 2 : 4 : 2, respectively, when the associated valves are non-conducting, and corresponding currents away from the meter when the associated valves are conducting, the other terminal of the meter being connected to a potentiometer 19 adjusted to a potential mid-way between the two possible potentials at the anodes of the valves. With this arrangement the algebraic sum of the currents passing through the meter increases in equal steps from a count of zero to nine, so that the meter provides an indication of the number of pulses counted. Instead of a centre-zero instrument, a normal meter could be used after appropriate adjustment of the potentiometer 19. Specification 572,884 is referred to.

Title: Improvements in golf clubs
IPC: A63B53/02
Filed: 1933-08-09
Abstract: 417,010. Golf clubs. METALLIC SHAFT CO., Wilmington, Delaware, U.S.A. Aug. 9, 1933, No. 22295. Convention date, April 6. [Class 132 (ii).] A golf club comprises a head having a hollow socket, a steel shaft having a hollow end inserted in said socket, and a torsionally resilient link secured at one end to the shaft and at the other end to the socket to allow slight relative rotation of the head with respect to the shaft. A high carbon spring steel connecting member or link 33 with concave edges connects the metal shaft 36 and head 30, having a hexagonal socket 31 merging into a circular end 32, and has an hexagonal end 34 connected by pin 37 to the shaft 36 and has placed on the circular end 35 members 40, 45, Figs. 13 and 14, of rubber and thin sheet steel respectively with strips 41, 46 respectively, extending along the flat faces of the hexagonal end of the shaft 36 which merges into a circular end. The shaft may be round and only that portion which enters the socket 31 hexagonal or the entire shaft may be hexagonal. The shaft with the coverings of rubber and steel so applied is driven tightly into the socket 31 and a hole is drilled through the socket 31, the end 35 of the connecting member 33, and the layers of rubber and steel, to take a pin 47 which is riveted at both ends and flushed to the outer surface of the socket. If unvulcanized rubber has been used it can now be vulcanized. A resilient sleeve or thimble 50 which can be slipped on to the small end of the shaft before it is inserted in the socket is secured in position against the end of the socket. By the construction described, relative longitudinal movement between the shaft and the head is prevented whilst relative torsional movement is allowed at impact to be followed by a quick and powerful rebound due to the resilient connecting member 33. In modifications, the connecting member 33 may be formed wholly from a piece of spring steel of flat or circular cross-section, or the enlarged ends of the member 33 may be made separately, slotted and the centre portion of the member 33 is pinned in. In this construction the lower end of the member 33 is preferably made of non-metallic material such as fibre or compressed rags composition. The member 33 may be positioned as in Fig. 20 in which only the end 34 is in the shaft. The rubber member 40 with fingers 41 may be replaced by a moulded rubber cap or sleeve 51, Fig. 19, which may be perforated or corrugated to provide room for displacement. The faces of the hexagonal shaft 36 may be concave or convex instead of flat and the internal faces of the socket 31 made to correspond. The invention may be applied to wooden-headed clubs having a socket closed or open at its lower end, the socket being burned to hexagonal shape by inserting a redhot hexagonal taper arbor in a small round tapered hole in the socket. The shaft and socket may be of any polygonal cross-section.

Title: Improvements in or relating to ammunition projectiles
IPC: F42B30/04
Filed: 1947-08-12
Abstract: 628,931. Ammunition projectiles. SAGEB SOC. ANON. DE GESTION ET D'EXPLOITATION DE BREVETS. Aug. 12, 1947, No. 22354. Convention date, Feb. 10, 1941. [Class 9 (i)] A projectile having a forward closure member and a finned tail contains a composite charge comprising a rear portion of easy ignition and high rate of detonation and a less sensitive portion of higher detonation rate, the less sensitive portion having a conical recess with a lining at the forward end. Fig. 1. shows a rifle grenade comprising a steel body 11 to which is attached a nose 10 of sheet metal and a hollow tail 12. The body contains an explosive charge 29 having a re-entrant conical cavity with a metal lining 30. Screwed into the body 11 is a base fuze assembly 25 having a metal jacket containing a primer 26 and a booster pellet 27. The nose 10 carries a nosepiece 35 secured against axial movement by a copper pin 36 and having an internally threaded bore in which is seated a firing pin 38 extending through a guide boss 37 to an aperture 25a in the fuze assembly. Situated in an aperture 39 intersecting the aperture 25a is a safety pin 40 having a threaded portion engaging in a threaded hole in the projectile body 11. The pin 40 is withdrawn by means of a ring 42. The threaded bore of the nose-piece is closed by a screw-plug 44 so seated that the firing pin has a slight play in the nose-piece. Before firing the grenade the safety pin 40 is removed. On impact of the nose-piece with the target the pin 36 is sheared and the firing pin 38 driven rearwardly to ignite the primer 26. The primer ignites the booster pellet 27 which ignites through flash passages in the fuze assembly an annular detonating charge 28 of pressed explosive of nitro or nitric ester type. This charge in turn ignites the main charge 29, a cast explosive of the same type as the detonating charge. Whereupon the lining 30 collapses and is propelled forward at a high velocity. After removal of a closure plug 50 and extraction of a rifle cartridge 55 stored within the tail 12, the grenade is fired by inserting the muzzle of a rifle within the tail and placing the cartridge in the rifle-breech. The rifle muzzle is fitted with a grenade-sleeve for frictional engagement with the grenade tail.
