Title: Improvements in or relating to gun fired projectiles
IPC: F42B14/06
Filed: 1942-07-30
Abstract: 585,794. Projectiles. BURNEY, SIR C. D. July 30, 1942, No. 10667. [Class 9 (i)] A subcalibre projectile has a driving collar 2 at the medial point of its length adapted to disintegrate under centrifugal force after the projectile has left the muzzle of the gun and another member 6 at its rear end for guiding and centralising and which permits free access of the chamber gases to the driving collar. The collar members may be screwed to the projectile body or provided with interfitting ribs and recesses 28 and to facilitate disintegration the medial driving collar may be formed in detachable segments enclosed by a thin tapered driving ring and sleeve 3 having an interfitting rib 9 with the projectile body, so that chamber gas-pressure thereon tends to press the sleeve on to the segments and prevents the access of gas to the screw-thread or rib attachment. The rear member 4 is also formed in sections perforated at 5 to allow free passage of the pressure gases to the space behind the driving member and the segments are surrounded by a band 6. The rear fitting may take the form of a helical vaned member or a weakened ring with projections 19, Fig. 11, tipped with copper 22. The driving member 2 may be provided with a separate ring 25 and conical sleeve 26 which covers the entrance to the joint between the driving member and the body of the projectile or a separate ring with coned surface secured to the body by wedges. The rear of the projectile may be of streamlined form and may be perforated to balance the pressures within and without. The driving band 3 may be positioned upon the rear guiding device of the projectile instead of upon the forward driving collar in which case the forward driving collar is fitted with a gas-check ring of soft metal such as lead.

Patent GB-465313-A (GB)
Title: Refractory product and process for its manufacture
IPC: F27B14/10
Filed: 1936-04-17
Abstract: Refractory articles are made by baking a mixture of silicon carbide, graphite, and a metal or alloy, or a metal oxide capable of combining with the silicon of the carbide to form a metallic silicide, in quantity insufficient to combine with the whole of the silicon of the silicon carbide.  Examples of metals employed are iron, nickel chromium and manganese, either as such or in the form of alloys or oxide.  The raw mixture may also contain an organic binder.  When the mixture is heated to 1100-1300 DEG  C. it matures to a refractory substance comprising particles of silicon carbide and graphite bonded by a metallic silicide.  The baking however may be at a lower temperature 800-900 DEG  C. to form products which can be handled, the maturing of the bond then taking place during a second heating to a higher temperature 1100-1300 DEG  C.  When the metals are added as oxides, a fluoride, e.g. fluorspar or cryolite is added.  In an example, a raw mix comprises 36 kgs. of graphite in flakes, 60 kgs. of silicon carbide, 12 kgs. of white sand 16 kgs. of ferromanganese alloy and 50 kgs. of organic binder, e.g. tar.  This is shaped, e.g. as a crucible, and baked at 800-900 DEG  C. for about 8 hours.  A protective glaze is developed when the article is heated to a higher temperature, about 1200 DEG  C. either in use or by a special baking. In another example the metal is in the form of iron oxide and chromium oxide, and a double fluoride, physalite, is added.

Title: Time recorder
IPC: H04M15/30
Filed: 1973-03-07
Abstract: 1423711 Time recorder SIMPLEX TIME RECORDER CO 7 March 1973 [20 March 1972] 11116/73 Heading G4T [Also in Division B6] A time recorder, e.g. for timing long distance telephone calls, includes time wheels, a hammer for urging a time card and an ink ribbon against the time wheels, a manually-operable linkage for rotating a plate, a hammer cocking and firing mechanism which includes an annular row of cams and which is actuatable by the plate, and a further mechanism actuatable by the plate for centring a character on one of the time wheels. As shown, Figs. 4 and 5, relatively staggered card slots 15 and 14 separated by a wall. 21, are provided for producing a corresponding spacing between the printed starting and finishing times. Depressing a lever 16 produces clockwise (Fig. 5) rotation of both a plate 57 and, through pawl and ratchet 59/62, a toothed wheel 72. Projections 99, Fig. 8, of arms 67, 68 are thus urged towards the tips of teeth 72 to pivot arms 67, 68 against the action of spring 71, Fig. 5. When the tips of teeth 72 pass the tips of projections 99, the spring 71, acting on connecting bar 69, throws the arms 67, 68 against a plate 66 carrying platens 101, 102. Plate 66 is thus pivoted about shaft 31 against the action of a relatively weak spring 72<SP>1</SP> to urge the time card and a typing ribbon (not shown) against time wheels (not shown). Rotation of plate 57 also acts to shift a member 75 (Fig. 5), the latter carrying a pawl 89 (Fig. 8), which indexes a ratchet 91 carried by one of two typing ribbon spools, and also carrying a lug (not shown), which acts on a device for aligning the nearest whole number type face of the lowest order (seconds) time wheel for printing, Figs. 12-15 (not shown). This lowest order type wheel is continuously driven from an electric motor via a coupling (Fig. 12), which permits the necessary forward or backward angular adjustment necessary for printing alignment. The other order type wheels are indexed by pawls associated with a plate that is oscillated by a cam driven by the electric motor; locking pawls are also provided for these other order type wheels, Figs. 16 and 17 (not shown). The electric motor also drives indicator wheels 43. The amount of ribbon left on the feed spool is indicated at 33.

Abstract: 621,622. Forging; shearing. STEVENS, A. H. (National Machinery Co.). April 11, 1946, No. 11140. [Class 83 (iv)] Forging-dies.-In a header such as that disclosed in Specification 601,977, comprising a shearing bush movable from a stock-feeding and shearing station into alignment with a die into which the sheared blank is pushed by a plunger within the bush, the diameter of the die is greater than that of the stock and the shearing bush is arranged to cut off a blank longer than the depth of the die. The die-holding member 10 of a multiple header has an aperture 11 through which stock S is fed into a shearing bush 16 carried by an arm 15, until a plunger 19 therein has been pushed back into engagement with a gauge stop 18. The bush 16 is then moved to shear the stock and carry the blank 24 into a position opposite a die-aperture 13 of greater diameter, into which it is pushed by the plunger 19 under the action of a punch 23. Continued movement of the punch causes the plunger to upset the blank as shown in Fig. 4. As the punch retires a spring 26 withdraws the end of the plunger from the die so that the shearing member may return, carrying the plunger with it in such a position that it will not contact the side of the gauge 18. The header slide 22 may then be operated again to perform a second operation on the blank. In a modified form, Fig. 8, the shearing bush 78, on the side opposite to the cutting edge, is recessed at 83 to insure against interference with the end of the blank when the arm 77 is retracted. The die 42 is mounted in a bore in the frame 41 with limited longitudinal movement against the action of a spring 48, which also serves to retract the ejector rod 50.
