Title: Method and appararatus for manufacturing continuous glass filaments
IPC: C03B37/083
Filed: 1973-02-15
Abstract: 1420136 Glass fibre manufacture OWENSCORNING FIBERGLAS CORP 15 Feb 1973 7552/73 Heading C1M In the formation of glass filaments, molten glass 66 in a container 10 is flowed through orifices 64 to form filaments 18, the orifices 64 being formed in a floor 14 comprising a layer 48 of porous material exposed at the external surface 50, a fluid being supplied under pressure through a tube 38 to the layer 48 so that the fluid is emitted from the external surface 50 to assist in separation of the glass streams 16 from the surface 50. As shown in Fig. 3, a non-porous plate 46 of high heat resistant material such as Pt or a Pt alloy forms an inner wall and has inner extensions 68 to form the orifices 64 and side 52 and bottom 53 portions joining with the porous layer 48, also Pt or Pt alloy, to form fluid passageways 58. Fluid passageways 60, 62 are formed in layer 48 to allow distribution of the fluid over the whole floor 14. A number of variations of orifice constructions are shown, in which the lining may extend beyond the surface 50; the lining may extend only part way down the orifice or no lining may be provided. The inner wall 46 may be dispensed with; two layers of different porosity may be separated by a non-porous plate. Tin shields may be used between the orifices. The fluid used may be a gas, air or steam. Particular gases suggested are carbon dioxide mixed with a small percentage of an organic such as hydrocarbon, propane being preferred; an inert gas, such as nitrogen, helium, argon, neon and xenon mixed with a hydrocarbon in small percentage and anhydrous ammonia alone or mixed with an inert gas. Specification 1,375,423 is referred to.
Patent GB-374875-A (GB)
Title: Improvements in radial-cylinder internal combustion engines working with liquid fuelinjection
IPC: F02B75/22
Filed: 1931-03-12
Abstract: 374,875. Oil engines. THAHELD, F. A., 1403, Pennsylvania Avenue, Dallas, Texas, U.S.A. March 12, 1931, No. 7700. [Classes 7 (iii) and 7 (vi).] Cylinders receiving liquid fuel; valve gear; regulating.-In a radialcylinder oil engine, the fuel is supplied to the injectors by pumps 126, Figs. 3 and 7, and pipes 99, the pumps being connected together by passages 121 formed in the crank-case wall and connected at 171 to a pipe 170 leading to a further supply pump. The pump plungers 126 are actuated by rockers 129 and cams 142 so as to draw fuel from the passages 121 through ports 125, and force the same through discharge valves 118 to the injectors. The cams 142 are formed on a flange 140, Fig. 11A, at one side of a disc 88, which has at its other side a second flange 881 formed with cams 89 which actuate the airinlet and exhaust valves 60 through tappets 81 and push rods 79. The pump rockers 129 are pivoted to a disc 138, by angular adjustment of which the timing of the injection and the stroke of the pumps are varied. This adjustment is effected by actuation of a plunger 160 connected by a link 158 to a lug 159 on the disc 138. This disc is connected to a decompression ring 136, which may thus be also angularly adjusted to bring decompression cams 162 under the tappets 81, thereby lifting the valves 60. When this occurs, the pump rockers 129 are adjusted so far that their pivotal ends come beneath the plungers 126, Fig. 7, so that the rockers are not operated. The plungers are, however, sufficiently raised to close the supply ports 125 and prevent air from entering the fuel line. The cam disc 88 is formed with internal teeth gearing with a pinion 155, Fig. 3, connected to another gear wheel 151 meshing with a pinion 150 on the crank shaft. The combustion chamber is constituted by an eccentricallyformed depression 109, Figs. 3 and 19, in the piston head offset towards a radial groove 109<1> communicating with the injection valve 80. This valve comprises a plunger 211, Fig. 22, formed at one end into a needle valve 102 controlling an injection nozzle 106 of Venturi form, and bearing at the other end against a spring 103. Fuel supplied by the pump enters through passages 220, 221 and opens the valve against the pressure of the spring 103. Fuel leaking past the plunger 211 is withdrawn through a byepass 222 by the force of the injection. Valves.-A single poppet valve 60 in each cylinder head serves both for exhaust and air-admission.

Title: Improvements in or relating to Hand Grenades.
Inventor: SIEGWART HANS
IPC: F42C14/02
Filed: 1916-06-05
Abstract: 102,332. Siegwart, H. June 5, 1916. Projectiles; projectile fuses. - Relates to safety devices for handgrenades, and consists in means for arming or igniting the fuse by the release of an external member, which release is initiated by the grip of the hand when throwing and is completed automatically when the grenade leaves the hand. The grenade shown in Fig. 1 comprises a wrought-iron cylinder 1 having external fragmentation grooves 4, the cylinder being closed at each end by a cover 2 secured by bayonet-joints or by screwing. There is an intermediate cover 6, to which is secured the fuse-tube 7. Within the tube is a primer 8 carrying a cap 8<1>, which is normally held away from the firing-pin 21, against the action of a spring 15, by a rod 16 interposed between the member 8 and a ball 25. This ball abuts against the lower end of a tube 29, projecting externally, and is normally locked by a pin 13 connected to a sleeve 30, which fits over the part 29. The end of the sleeve 30 is slit so as to form claws, which engage in a groove in the part 29 and are secured against accidental displacement by a strip of waterproof fabric bound by a wire 20. The claws may be turned up into an annular slot, so that the strip may be bound under their ends. In use, the wire and strip of fabric are first removed, and the thrower presses down the sleeve 30 with his forefinger in the act of throwing. This causes the claws to be disengaged from the groove and spread apart by a conical portion of the surface of the part 29, so that when the grenade leaves the hand, the sleeve 30 and rod 13 are ejected by a spring 28, thus releasing the ball 25. On impact, the ball is dislodged, and the spring 15 effects ignition. Fig. 2 shows a modification in which a time-fuse 8<11> is ignited when the grenade .is thrown. The timefuse is contained in a spring-pressed member 8, which is normally held away from a firing-pin 21 by a rod 16 secured to a sleeve 30.
