Title: Improvements in or relating to blowpipe burners for cutting, welding, and similar metal working operations
IPC: F23D14/38
Filed: 1934-09-13
Abstract: 449,003. Blowpipe burners. LINDE AIR PRODUCTS CO., 30, East 42nd Street, New York, U.S.A. Sept. 13, 1934, No. 26323. Convention date, Oct. 28, 1933. [A Specification was laid open to inspection under Sect.91 of the Acts, March 14, 1935.] [Classes 75 (i) and 75 (iii)] The admission of a fuel gas such as acetylene, a combustion-supporting gas such as oxygen and atmospheric air to a blow-pipe burner for cutting, welding, deseaming, and similar metal working operations is controlled directly or indirectly by a single means. In the metalcutting burner shown a block B at the rear of the handle H is fitted with an oxygen valve 29 and an acetylene valve 45 supplying the heating flame, these valves being operated against spring pressure by a single lever L. The neck 68 of the stem of the valve 29 is shorter than that of the valve 45 so that the oxygen is admitted earlier and shut off later than the acetylene. The oxygen supply pipe is connected to a chamber 20 in the block B from which it passes through a control valve V‹ and a tube 25 to a cavity 26 in the burner head He and then returns by a tube 25<a> to the inlet chamber 28 of the valve 29. The acetylene supply pipe is connected to a control valve V<a> which is directly connected to the valve 45. When the valves 29, 45 are opened the oxygen passes to a central passage 38 in a nozzle 33. The oxygen issuing from the nozzle 33 creates a subatmospheric pressure in a surrounding chamber 39, thereby inducing a flow of acetylene through a passage 48 and an exchangeable metering plug 46 from the valve 45 and a flow of air through passages 54 in the nozzle connected to a cap 50 formed with an air inlet 49. The cap 50 comprises two chambers separated by a perforated partition 50<a> covered by a flap-valve 51 preventing back-flow. The mixed oxygen, air, and acetylene are delivered into the throat 55 of an expansion chamber 56 and pass through a tube 57 to a distributing passage 58 in the burner head He. The heating gases are ignited by means of a pilot burner P clamped to the tube 57 and supplied with acetylene from the inlet chamber of the valve 45 through pipes 75, 94 and a regulating- valve 76. When ignition is to be effected a valve 82 is operated against spring pressure to byepass additional gas around the valve 76 and so increase momentarily the pilot flame. The pilot burner nozzle 99 is formed with air openings 102 and is surrounded by a shield 100 formed with air openings 103. The cutting oxygen is supplied to the head H<e> under the control of a valve 107 which is operated by a lever 117 through, a sliding plunger 120. The knob C of the lever 117, the button 90 of the valve 82, and the actuating arm of the lever L are located so as to be operable easily by the thumb and fingers of the operators' hand gripping the blowpipe handle H. In a modification the fuel gas is admitted to the central passage of the nozzle 33 under sufficient pressure to aspirate the air and oxygen into the surrounding chamber 39.

Title: Improvements in or relating to absorption wattmeter arrangements
Inventor: BROCKELSBY CHARLES FOUNTAIN
IPC: G01R21/00
Filed: 1948-10-08
Abstract: 648,944. Power meters. MARCONI INSTRUMENTS, Ltd. Oct. 8, 1948, No. 26330. [Class 37] An absorption wattmeter arrangement comprises a wattmeter connected to input terminals through a transformer having at least one winding untapped and a variable impedance network. As shown, the primary P only of the transformer I is tapped, resistances R being introduced between each tapping and a switch SW by which the input terminals IN are connected to the appropriate tapping. The secondary S is untapped and connected to the wattmeter W through a resistance network RN comprising series and shunt adjustable resistance elements which may be ganged. The impedance changing pad RN is adjusted to keep the same substantially constant overall efficiency at all of its settings and is arranged to give an impedance selector action fixing the significant figures of the input terminal impedance, while the primary tappings give a decimal multiplier action, fixing the position of the decimal point. Maximum efficiency is obtained if the shunt resistance in the network RN becomes infinite when the network is set for maximum impedance and the series element reduces to the winding resistance of the transformer secondary when the network is set for the lowest impedance. Alternatively the transformer secondary may be tapped and connected to the wattmeter and the variable impedance network provided between the untapped primary and the input terminals.

Title: Improvements in or relating to the manufacture of insoles for boots or shoes
IPC: A43B13/38
Filed: 1930-09-04
Abstract: Insoles for boots &c. are reinforced by applying to the non-tacky coated face of a strip of suitable width cut from a web of fabric coated with cement composition, a coating of cold viscous rubber cement composition and, while the composition is still cold, but tacky, applying a portion of the strip to the insole.  The rubber cement composition contains rubber and a filler, such as zinc oxide, in approximately equal proportions, and Burgundy pitch in excess of the rubber content, dissolved in a very volatile solvent, such as naphtha solvent which is substantially free from the higher boiling point constituents usually found in such solvents.  A thin coating of a composition containing 65 lbs. of rubber, 51 lbs. of zinc oxide, 22 lbs. of Burgundy pitch and 36 galls. of naphtha contained in a trunnioned receptacle is applied to a web of duck fed from a roll to a coating apparatus.  The coated web is then passed over a series of steam pipes which drive off the volatile solvent and dry the web. The dry non-tacky coated web is wound on a roll and divided into a number of strips each of a width necessary to cover the insole, and the strips are further wound into rolls.  A thicker coating of a composition containing 48 lbs. of rubber, 48 lbs. of zinc oxide, 60 lbs. of Burgundy pitch and 12 gallons of naphtha, preferably that distilling over between 165 DEG  and 238 DEG  F., is applied to the strips, the coating not extending to the edges of the strip.  In a very short time the solvent in the second coating dries off or softens the first coating to unite the coatings into a single tacky coating for attachment to an insole.  Pieces of the required length are cut from the strips and pressed into contact with the insole.

Abstract: 409,988. Centrifugal gas - cleaners. SOC. D'ELECTRICITE DE LA REGION DE VALENCIENNES-ANZIN, 75, Boulevard Haussmann, Paris. Sept. 25, 1933, Nos. 26373 and 26374. Convention dates, Sept. 28, 1932 and July 26, 1933. [Class 23.] Dust - laden gases are freed from the dust particles during their passage through a separator which has a number of curved guide members d<1>-d<5> to divide the gaseous flow into a number of streams of small thickness. Each guide member has a dust trap P ; these traps are offset in relation to each other owing to the different lengths of the guide members and they are inclined to permit the dust particles to descend to the passages t and the chamber C. Plates T are associated with the guide members to form chambers leading to the traps P. Each plate T has a series of louvre-like apertures a<1> which can be formed by slitting the plates T and raising the edges of the slits. The chambers may have increasing cross-sectional areas from the points of entry to the traps P. This assists the entry of the heavily laden portions of the gas stream into the chambers.

Title: Improvements in and relating to fluid pressure measuring apparatus
Inventor: SINGH DEEP NARAYAN
IPC: G01L7/16
Filed: 1957-08-22
Abstract: 891,026. Gravity-controlled pressure gauges. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 22, 1958 [Aug. 22, 1957], No. 26583/57. Class 106 (2). In a fluid pressure measuring apparatus the pressure to be measured is balanced in part by a piston 14 loaded by dead weights and in part by the action of a liquid between a container 18 and a displacer 21 which are moved relatively to one another by the movement of the piston, the container 18 being fixed and the displacer 21 movable. The pressure to be measured is introduced at 11 and acts on a piston 14 sliding in a cylinder 13. The piston 14 carries a weight platform 17, and a cylindrical weight 16. Also carried by the piston is an annular displacer 21 which moves inside the liquid container 18, the amount of liquid displaced being indicated by a monometer 24. To prevent sticking due to friction, the platform 17 is rotated by members 32 engaging its periphery and driven by a motor 27. In use, the pressure is approximately measured by a Bourdon tube and the platform is suitably loaded so that the measuring range includes that pressure. The monometer reading is then used to determine the pressure, the weight of liquid displaced being subtracted from the total loaded weight of the piston 14. This is of use for negative pressures and small positive pressures. Also described, Fig. 2 (not shown), is a way of converting the apparatus for use with a fixed displacer and a movable liquid container carried by the piston 14. In this case, the liquid displaced acts in conjunction with the load on the piston, thus enabling the apparatus to be used for high positive pressures. The liquid used is preferably oil, and to prevent this being sucked into the system of which the pressure is being measured, an air vessel is included in the connecting line. A mercury seal may also be used between the oil and the system. Means such as a large reservoir may be provided to damp pressure fluctuations.

Abstract: 745,761. Rotary printing machines. VEB DRUCKMASCHINENWERK VICTORIA VVB. POLYGRAPH. Sept. 28, 1953, No. 26608/53. Class 100 (2). In a sheet-fed rotary printing-machine including driven impression and plate cylinders and a delivery or transfer device, including an intermittently-driven drum moving an endless conveyer on to which sheets after printing are delivered, and having means for tripping the impression cylinder in the event of incorrect sheet feed, the printing mechanism is driven separately from the delivery drum from a main driving shaft and the delivery drum is so positioned that the throw-off movement between the impression and plate cylinders can be made approximately radially. As shown, a vertical main shaft 12 is driven by a motor 15 through worm gearing 13, 14. An intermediate shaft 17 is driven from the shaft 12 through spiral bevel gears 16, 18, and the shaft 17 drives a sheet delivery drum 22 through a train of helical gears. A second intermediate shaft 27 is driven from the shaft 12 through spiral bevel gears 23, 24 and a pair of helical gears, and this shaft drives the shaft 32 of an impression cylinder 5 through a second pair of helical gears on the opposite side of the machine frame. The cylinder 5 has a helical gear thereon meshing with a similar gear on the plate cylinder 6. The inking-apparatus 2 is driven by bevel gears from a shaft 34 which is driven from the shaft 12 by bevel-gears 33, 35. The shaft 32 of the impression cylinder 5 is mounted in eccentric bushes to allow the cylinder to be tripped away from the cylinder 6 in a direction approximately radially of the latter and towards the drum 22. Sheets are fed over a table 7 to front and side registers 8, 9, and fed to the impression cylinder 5 by oscillating gripper means 10. Sheetdetector and control fingers 11 can initiate the tripping of the cylinder 5 in the event of faulty sheet feed to the table 7.
