Title: Improvements in or relating to gas burning pyrophoric lighters
IPC: F23Q2/16
Filed: 1950-10-27
Abstract: 681,124. Pyrophoric igniters. MELLER, E. A. Sept. 28, 1951 [Oct. 27, 1950; June 25, 1951; Sept. 21, 1951], Nos. 26224/50, 15003/51 and 22142/51. Class 75(iii) [Also in Group XXIX] A gas-burning pyrophoric lighter comprises a casing, a container therein for liquefied gas fuel, pyrophoric ignition striker mechanism carried on the casing, and outlet valve means for the container comprising a deformable resilient regulator, serving for adjustment of the size of the flame from the exterior of the lighter, and also serving as the valve-member of a shut-off valve for the gas adapted to be actuated by the ignition striker mechanism. On actuating the flint wheel 2, Fig. 1, by means of a press button 5 a plunger 7 extending downwardly from the latter depresses an end of a lever 11, having an aperture 12 freely engaging the flint tube 13, to raise the opposite end of the lever which lifts a flange 15 on a cut-off valve controlling the flow of gas from a fuel container 16. The valve comprises a body 43, Fig. 2, threaded into the wall 49 of the fuel container, and a member 45 biassed by a spring 46 against a resilient pad 47 to cause the latter to close the inner end of the inlet passage 48. When the lighter is operated the member 45 is raised by the lever 11, Fig. 1, or by the lever 53, Fig. 2, and allows the gas pressure to raise the periphery of the pad 47 to an extent determined by the screw-threaded adjustment of a hollow plug 44, thereby permitting a controlled gas flow through the valve. In order to avoid an accumulation of liquid (the liquefied gas) in the valve which might cause an enlarged flame on opening the valve the latter may be enclosed in and spaced from a cylindrical casing having apertures above the normal level of the liquid (liquefied gas) fuel for the passage of the fuel in the gaseous state only.

Title: Improvements in or relating to air cushion vehicles
Inventor: BENNISON MICHAEL JEREMY
IPC: B60V1/00
Filed: 1961-07-21
Abstract: 953,910. Air cushion vehicles. VICKERSARMSTRONGS Ltd. July 6, 1962 [July 21, 1961], No. 26566/61. Heading B7K. A vehicle adapted to ride on a non-compartmented air cushion formed on the underside of the vehicle within means encircling the cushion and including a curtain arranged to be produced by air issuing from downwardly directed orifice means on the perimeter of the underside of the vehicle has means provided for stabilizing the vehicle against tipping including an orifice or orifices for introducing air into the cushion, the orifice or orifices each being of limited lateral extent so that air issuing therefrom cannot form a curtain compartmenting the cushion, the arrangement being such that in operation when the vehicle tips air from said orifice or orifices flows towards the side of the vehicle having the higher ground clearance, an increase of pressure occurring in the cushion towards the opposite side of the vehicle whereby the tipping is opposed. The vehicle comprises a peripheral orifice 2 which is enlarged at the positions marked 3-6, so that when the vehicle pitches so that, say, the ground clearance at location 3 increases and that at location 5 decreases, cross flows 8 and 10 from enlargements 4 and 6 result. This involves an increase in pressure on the convex sides of the flows so that the pressure in the zone 11 of the cushion 1 builds up to resist the tipping of the vehicle. Strokes may be formed on the base of the vehicle to direct the cross-flows. Alternative embodiments are described employing a single central orifice or a plurality of discrete slits or orifices arranged mutually at right angles in the base surface. Instead of a peripheral air curtain the cushion may be confined by sidewalls and end air curtains, or the peripheral curtain system may be constructed for recirculation.

Title: Explosive compositions
IPC: F42D1/00
Filed: 1960-04-20
Abstract: An explosive blasting composition comprises an inorganic oxidizing salt or peroxide dissolved in water and a thermal carrier having a particle size large enough to be retained by a 20-mesh U.S. Standard sieve. The thermal carrier is preferably magnesium, aluminium, or alloys thereof in the form of shavings, chips etc.; other suitable thermal carriers are the same as those referred to in Specification 952,837. The oxidizing salt may be a nitrate, nitrite, perchlorate, sulphate, chlorate, or chromate, especially ammonium nitrate, nitrite, or perchlorate.

Abstract: 279,820. Esau, A. Oct. 29, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Drawings to Specification. Aerials; fading, preventing; undesired signals, eliminating.-In order to prevent fading effects due to interference between the free and earthbound components of the radiated wave, two or more individually non-directive aerials are arranged in the same plane, and are spaced apart by a distance equal to one or more wavelengths. Transmission from such an aerial system is stated to consist wholly of high-angle radiation, the earthbound component being eliminated. Similarly reception is limited to waves coming from above a certain angle to the horizontal. The system can also be applied to prevent interference from a nearby transmitting station by suppressing the earthbound component from that station.
