Title: Method and means for the electrical ignition of fluid propellants
IPC: F42B5/08
Filed: 1973-12-17
Abstract: 1450068 Electrical ignition of fluid propellants RHEINMETALL GmbH 17 Dec 1973 [30 Dec 1972] 58246/73 Heading F3C [Also in Division F1] Means for the electrical ignition of fluid propellants comprises a detonating charge compartment accommodated in a detonating charge housing 1 and having chambers 3, 7 therein, the smaller chamber 3 having an electrode 4 and being connected to the chamber 7 through a passage 6, and the chamber 7 containing a system of channels 13. The housing 1 has an electrical connection 10 leading thereto. A ring 2 is provided to insulate the housing 1 from the electrode 4. The latter has a head 4a and is connected to an electricity supply by a contact 9. Funnel-shaped passages 5, 5 lead from the passage 6 to the respective chamber 3 or 7. In use the end of the housing 1 which is adjacent the channels 13 is attached to the charging compartment (not shown) of a weapons launching tube. Fluid propellant is conveyed into the detonating charge compartment of the weapon either via the charging compartment (not shown) or directly via a conduit 8. Electricity supplied to the electrode 4, via the contact 9, initiates the decomposition of the fluid propellant. The funnel-shaped passage 5 which connects the chamber 3 to the passage 6 provides a damming effect so that a conversion of the propellant from the liquid to the gas phase takes place and a gas-bubble is formed in the chamber 3. The gas-bubble has a thermal capacity and energy content great enough to ensure that the decomposition of the fluid propellant present in the chamber 7 will continue until conversion is complete. The intensifying effect of the chamber 7 and of the nest of tubes 13 enables the propellant in the adjacent charging compartment (not shown) to be ignited in an even and a reproducable manner without the use of a priming charge.

Abstract: 1446360 Making circular saws, Jointing, soldering GOMEX VERKTYG AB 28 Dec 1973 [17 Jan 1973] 60099/73 Headings B3A, B3R and B3V] [Also in Division B5] In a method of making a rotary saw blade comprising two discs interconnected by a layer of binding means, a meshed net 7 having a uniform overall thickness is disposed between the discs to position the discs parallel to each other so that the layer is of uniform thickness. Discs 1, 2 are pressed at 400‹-440‹C, flattened, surface ground and degreased. A copper, iron or plastics net 7, which may comprise more than one layer, is dipped into or coated with an adhesive containing electrically conductive powder, e.g. aluminium, and placed between the discs. The adhesive is then cured. The discs are made of rolled material and the fibre orientation of each disc resulting from rolling is offset relative to the other, preferably at 45 degrees. The discs are spot welded to each other by a plurality of asymmetric welds 6. In an alternative construction the net 7 does not extend as far as the teeth 3, Fig. 3 (not shown), and a layer of solder is applied to the peripheral portion (9), which is free of adhesive. After the adhesive has been cured the discs are ground so that they are of different thicknesses and the cutting edges 4 are soldered in position. In the alternative construction the peripheral portion is also heated to fuse the solder, this heating being preferably effected by high frequency current apparatus while rotating the discs. Finally the saw blade is straightened. The net may be metallic, e.g. copper or iron, and the binding means may be solder applied either by dipping or electro-deposition. The solder is preferably a silver solder having a fusion temperature of 600‹-625‹C. A plurality of nets may be used, either overlapping or adjoining and they may be of different materials. They may also be made of the bonding material so that they fuse on heating.
