Title: Improvements in burners for liquid fuel
IPC: F23D3/00
Filed: 1932-05-27
Abstract: 393,083. Wick-burners. LAMPENUND METALLWARENFABRIKEN R. DITMAR GEB. BRœNNER AKT.-GES., Erste Haidequerstrasse, Vienna. May 27, 1932, No. 15074. Convention date, June 5, 1931. [Class 75 (i).] A wick-burner is fitted with a device for extinguishing the flame burning initially at the surface of the wick, the vapours given off by the hot surface of the wick issuing through perforations in a chamber formed by the extinguishing device and becoming ignited. These flames may be regulated by adjusting vertically the wick or the fuel level. In the burner shown in Fig. 1 a cap 6 may be lowered over the burning surface of a vertically adjustable wick 2 to extingush the flame and the vapours issue through holes 7 in the cap and become ignited. In the modification shown in Fig. 2 a sleeve 8 may be raised about a non- adjustable asbestos wick 2 into contact with a fixed disc 8a, the vapours escaping from the wick becoming ignited at holes 8b in the sleeve. In the burner shown in Fig. 4 the flame from a tubular wick 2 burns initially at registering slots 12, 12<1> in a safety disc 11 and a regulating disc 20, the disc 11 being mounted on a cylinder 16 and supporting perforated cylinders 17, 18 forming the combustion chamber and a protecting cylinder 19. The cylinders 17, 18, 19 are connected by a pin 21 and the inner cylinder carries the disc 20 so that by turning the outer cylinders by a handle 22 the position of which is indicated by a scale on the disc 11, the flame from the slots 12, 12<1> may be extinguished. The vapours from the wick then pass through perforations 15 in the disc and become ignited. The flame may then be regulated by means of a wick lifter 24 having a sliding pointer 25 which is held on the lifter by a leaf spring 25a and indicates on a fixed scale 26 the amount by which the wick has been lowered from the disc 20. In the modification shown in Fig. 7 the regulating disc 27 is provided with perforations 27a only in its inclined portion and the cylinders 17, 18, 19 can be raised for ignition of the wick or lowered to extinguish the initial flame by rotating a handle 28 engaging an inclined slot in the flange 23 of the disc 11. The wick is adjusted vertically by a pinion 32 operated by a handwheel 31. The hand-wheel 31 is connected by a spring-loaded slip coupling with a scale disc 33 fitted with a pin 35 which limits the lift of the wick by striking against a stop 34. A fixed pointer 36 indicates the amount by which the wick has been lowered from the disc 27. In a further modification the cylinders 17, 18, 19 are stationary and the disc 31 can be raised into contact with disc 27 by raising the wick. A spring projection on the disc 11 then locks it to the cylinder 16 so that the wick may be lowered without the disc 11 to regulate the flame.

Abstract: 586,454. Testing machine-guns &c. GILSON, I. R. Aug. 10, 1944, No. 15249. Convention date, July 28, 1943. [Class 20 (i)] A bullet-catcher for receiving bullets discharged by machine-guns &c. during firing tests comprises a pipe consisting of aligned sections 11, 12, 13 through which a stream of mixed liquid and gas flows and into which the bullets fired by a machine-gun &c. 53 are discharged, the stream and bullets flowing into a tank 31 from which a pump 25 draws liquid for maintaining the stream through the bullet-catching pipe. The initial section 11 has two inclined nozzles 14 diametrically disposed, and a further pair of inclined nozzles also diametrically disposed but at 90 to and slightly in advance of the first pair. These nozzles are coupled by pipes 21 to a manifold 23 through which the discharge from the pump 25 passes, the liquid being projected through the nozzles at a sufficiently low pressure, indicated by a gauge 28, to avoid the formation of a solid stream. The liquid together with air entrained through the inlet to the section 11 flows into the shock section 12 of the pipe where the bullets make impact with the stream and have the major part of their kinetic energy absorbed thereby. The bullets and stream then pass along the tail section 13 of the pipe into the tank. Baffles 32 and 35 of armoured plate are fitted in the tank as a precautionary measure. The pump may be electrically driven by a motor 26. A drain 41 for the forward end of the section 11 leads into the tank, for which also a drain 36 is provided.
