Title: Improvements in stamping machines
IPC: B21J7/36
Filed: 1937-10-23
Abstract: 487,022. Power hammers. RENAULT, L. Oct. 23, 1937, No. 29010. Convention date, Dec. 3, 1936. [Class 83 (iv)] Relates to a drop hammer of the type in which the head is raised by the grip of constantly rotating rollers brought into and out of engagement at the two ends of the stroke with a plate or board attached to the hammer head, and consists in a construction enabling the stroke to be altered from a long to a short stroke or vice versa without stopping the machine. In the usual construction a stop 30 is provided on the head 5 for engagement with an adjustable pivoted lever 24 to move a controlling rod 22 and free the driving means from the board 7, attached to the hammer head. In the present invention, an additional stop 29 is provided at the other end of the head, and this stop projects less than the stop 30. The pivoted lever 24 is arranged, as shown in Fig. 4, to be capable of movement to the position shown, in which it is in the path of the stop 29, or alternately to be oscillated with its rod 22 to a position for engaging the stop 30. This action is effected by a spring pressed piston 37 in a cylinder to which pressure is admitted or released at 41.

Title: A process for the purification of tar-containing gases
IPC: C10K3/00
Filed: 1954-10-12
Abstract: 753,975. Purifying gases. OTTO & CO. GES., DR. C. KO-WE NIEDERSCHACHTOFEN GES., and FUCHS, W. Oct. 12, 1954 [Oct. 16, 1953], No. 29348/54. Class 55(2). In a process for purifying tar-containing gases, the gas containing tar in vapour or mist form is brought into contact with a non- metallic multi-substance catalyst which promotes the decomposition at comparatively low temperatures, e.g. 600‹-700‹C., of the tar into permanent gases, any non-gaseous tarry substances remaining in the gas are subsequently removed by cooling and/or washing the gas. A suitable catalyst consists of a mixture of a carbon-containing substance, e.g. coke, and a clay containing substance, e.g. montmirollonite, e.g. the coke being provided with a coating of the montmirollonite. High boiling point constitutents of the tar are converted into lower boiling point tar oils which are recovered by the cooling and/or washing step. In the event that the gases contain substantial amounts of high boiling point constituents the gas may require a second treatment consisting of passing the gas from the first treatment through or over a metallic catalyst whereby the residual high boiling point constituents are converted into low boiling point products. The catalyst may in this second treatment be in the form of a fixed or a vortex bed or the catalyst may be added in a finely divided state to the gas to be treated and subsequently separated therefrom by mechanical means.

Title: Improvements in or relating to gas-starter distributors for internal-combustion engines
IPC: F02N9/04
Filed: 1921-11-05
Abstract: 187,854. Fedden, A. H. R., Butler, L. F. G., and Bristol Aeroplane Co., Ltd. Nov. 5.1921. Starting.-In a distributor for supplying a starting mixture under pressure to each of the cylinders of a multi-cylinder engine upon its working and suction strokes, the conduit supplying the cylinders upon suction strokes is controlled by a valve actuated independently of the pressure of the system. In the form shown in Fig. 1. a valve chamber 1 is supplied with mixture bv a pipe 3 and is provided with a rotary engine-driven valve 8 controlling ports 5 connected by conduits 6 to the individual cylinders. A port 13 in the valve 8 supplies the cylinders on their working strokes. A port 14 leading to the cylinders on their suction strokes is normally closed by a valve 16, which is, situated on the axis of the distributor and can be opened by means of a forked arm 22 on a spindle actuated by hand or by mechanical or electrical means. In use, the supply of compressed mixture through the port 13 to the cylinder on this working stroke sets the engine in motion. The valve 19 is opened, enabling mixture to be supplied also on the suction strokes, when the ignition system may be put into operation and the engine started under its own power.

Filed: 1956-09-27
Abstract: 832,235. Catalytic cigarette lighters. FLORMAN, I. Sept. 27, 1958, No. 29555/56. Class 75(3) , A catalytic lighter comprises an element or elements heated by catalytic action, a resilient and flexible fuel housing provided with an air inlet and which upon manual compression or release produces a compression or suction on the fuel contained in the housing and means carried by the housing for directing vapours from the fuel and air sucked into the housing through the air inlet into contact with the catalytic element or elements. As shown a fuel housing 10 made of a resilient and flexible material such as polythene and having ribs 11 is provided with a hollow threaded neck 15 on which is adjustably screwed a cap member 18. The cap member 18 is provided at its lower end with a flange 21 which overlies air inlet apertures 20 in the top wall of the housing 10 when the cap member is screwed down. The hollow neck 15. is reinforced with a thin walled sleeve 34 provided with a bottom 35 on which is seated a rubber washer 36 which may or may not be provided with a projection 38 to keep a wire mesh layer 14 out of contact with the lateral cut-away outlet 37 in the bottom 35. Located within the sleeve 34 is a metallic cup shaped member 25 in which is seated a plurality of ring shaped catalytic elements 33a, 33b, 33c, 33d between wire mesh members 31, 32. A tube 26 is tightly secured in a central opening 24 to the bottom of the cup 25 and has fixed to its outer surface a rubber gasket 27 which engages the inner wall of the sleeve 34 and is sandwiched between upper and lower discs 28, 29 tightly fitting the tube 26. The cup 25 and its associated components is upwardly biased by a spring 30 surrounding the lower end of the tube 26. In the inoperative position the cap is screwed down so that the flange 21 covers the air inlet apertures 20 and a cover, or shoulder 39 engages the upper edge of the cup 25 to press the tube 26 on to the rubber washer 36 thus closing the fuel outlet. To operate the lighter the cap 18 is unscrewed to uncover the air inlet apertures 20 and to permit the spring 30 to lift the end of the tube 26 off the rubber washer 36. The housing 10 is pressed to force air and fuel through the outlet 37 and tube 26 over the catalytic elements 33a, 33b, 33c, 33d which will glow thus enabling a cigarette to be lit. On release of pressure the housing 10 returns to its normal shape thus drawing air through the air inlet apertures 20 into the fuel chamber.
