Title: Method for manufacturing bodies of a ferritic stainless steel
Inventor: BERGH SVEN SIGVARD
IPC: B22F9/00
Filed: 1966-02-22
Abstract: 1,136,022. Sintered ferritic stainless steel. WARGONS A. B. Feb.22, 1966 [March 10, 1965], No.7783/66. Heading C7D. Sintered ferritic stainless steel is produced from a cast ingot of the steel having a Cr content of 20-55% which is heat-treated at 600 -900 C. to produce a brittle phase, the ingot is then crushed and the powder formed is sintered. The powder of minus 325 mesh U.S.A. standard may be poured into a mould and sintered as a loose powder e. g. to form bearings and filters with a porosity of 40-50%, or it may be pressed at 4/8 tons/sq. cm. or rolled in a metal sheath sintered and rolled to form rods, bars and wires. The powder is preferably annealed at 900 -1100 C. prior to forming and sintering at temperatures above 1000 C. Fe and/or Al powder may be added to the steel powder to suppress the formation of sigma phase e.g. 10% of a 50/50 Fe/Al alloy may be added. Alternatively the powder may be annealed in a nitrogen atmosphere to form surface nitrides. To inhibit grain growth an oxide layer is preferably formed on the powder during annealing or alternatively iron oxide may be added to the powder.

Title: Improvements in or relating to apparatus for recording a multiplicity of variables
Filed: 1958-06-11
Abstract: 911,092. Pens for recording-Instruments. BALDWIN INSTRUMENT CO. Ltd., and BOYLE, P. W. Sept. 10, 1959 [June 11, 1958], No. 7837/58. Class 146 (3). [Also in Group XIX] Recording-apparatus comprises a number of electrically responsive arms 12 spaced apart in a horizontal line and movable, each in accordance with a different variable, in separate vertical planes, each arm 12 moving an element 17 which can be operated to mark a chart 18. Applied to paper-making machinery with a number of nucleonic substance gauges spaced to measure the weight per unit area at points across the width of a web of paper, the output from each gauge is amplified and applied to a moving coil instrument 11. The instruments 11 are spaced similarly to the gauges and their recording arms 12 rotate about a common axis. The record sheet 18 is guided so that the elements 17 record on a concave surface. The elements 17 may be pens, but preferably the record sheet 18 is heat-sensitive and the elements 17 are heated by current supplied through light-weight tubes 12, 13 in an appropriate timed sequence with the gauging operation and the step-by-step movement of the chart 18 so that the values are recorded across the chart while it is stationary, the marks being in effect points on a curve representing the variation of weight across the web of paper being gauged. The elements 17 need not touch the sheet 18, thus avoiding friction. An embodiment is shown, in which pin-and-slot connections in linkwork convert rotary movement of the arms into rectilinear movement of the elements so that recording can be made on a flat record sheet.

Abstract: 912,886. Measuring torque. BLACKBURN ENGINES Ltd. March 7, 1960, No. 8003/60. Class 106 (2). A device for measuring the torque on a shaft carrying an inclined tooth gear comprises a piston connected to the shaft and subjected to fluid pressure, the supply of fluid being increased progressively by displacement of the shaft due to end thrust. The piston has a constant leak and the pressure of fluid on the face of the piston gives a measure of the torque load on the gear shaft. As shown, a piston 3 is secured to the bearings 2 of a shaft 1 by a nut ring 4 and is enclosed in a fluid-tight casing 5 having end walls 6, 7. A fluid-tight seal is made between piston 3 and end wall 6 by bellows 8. Fluid at constant pressure is supplied through a union 9 to an annular passage 10 in the casing 5 and passes through ports 11 in a tubular member 12 and through ports 14 in a sleeve 13 slidable with piston 3. The ports 11  register with ports 14 to a greater or lesser degree according to the position of the piston 3. The fluid passes through an aperture 16 into the casing chamber in front of the piston 3. Some of the fluid escapes through a bore 18 and this together with fluid passed through bores 20, 21 and jet 22 to lubricate the bearings 2 is drained away. The pressure on the face of piston 3 is read by a meter (not shown) connected by a union 17.

Abstract: 512,800. Treating yarns and foils with hot liquids. DREYFUS, H: March 16, 1938. Nos. 8147 and 19730. [Classes 2 (ii) and 15 (i)] Processes for the treatment of yarns, foils and the like with hot liquid media under pressure, e.g. stretching, shrinking and saponifying, are carried out by passing the materials through a hot liquid medium contained in a vessel which also contains heating means for maintaining the temperature of the medium and a shield or shields so positioned as to protect the materials from disturbance due to the heating means. The best arrangement is one in which heating means is positioned on one or, preferably, both sides of the materials and a vertical shield is interposed between the path of the materials and each heating means. Alternatively, the heating means may be positioned below the materials and a wire gauze or perforated plate may be positioned between the heating means and the materials, or the materials may be surrounded by a perforated shield. The vessel is preferably kept only one-half to two-thirds full of liquid. In Figs. 2 and 3, the yarns pass between the vertical shields 15 contained in the vessel 7, which also contains a perforated coil 10 for the introduction of hot liquid medium and a perforated coil 11 for the introduction of steam. A liquid level gauge 16 also is provided. The process is particularly applicable to the treatment of yarns, foils or the like of organic derivatives of cellulose.

Title: Improvements relating to the treatment of hydrocarbon fractions
IPC: C10G65/04
Filed: 1961-03-07
Abstract: Hydrocarbon fractions boiling above 150 DEG  C., e.g. heavy gas oils, are treated to reduce their content of aromatic compounds and nitrogen compounds, and are then contacted in the presence of hydrogen with a platinum group metal on a refractory oxide support at a temperature of at least 600 DEG  F. and a pressure of at least 100 p.s.i.g., the temperature and space velocity being correlated to give a product boiling above 150 DEG  C. having a pour point at least 5 DEG  F. lower than the pour point of the feedstock.  The cloud point and freezing point of the fractions may also be lowered. Suitable hydrogenation conditions are: .Temperature.600-950 DEG  F .Space velocity.0.1-8 v/v/hr .Pressure.100-1500 p.s.i.g .Hydrogen :hydrocarbon mole ratio.1:1- .20 : 1.. The process may be operated with or without a net hydrogen consumption.  The catalyst support may be one or more of the oxides of metals of Groups II, III and IV, preferably alumina containing 5-25% wt. silica.  A minor proportion of one or more compounds of non-metallic elements of Groups III, IV and V, e.g. boron or phosphorus, may be present.  The catalyst may also contain halogen, e.g. fluorine or chlorine.  Further, halogen may be added to the reaction zone to increase the activity of the catalyst, either as such or in the form of a compound which decomposes to the halogen under the reaction conditions, e.g. as hydrogen halides or as halogen derivatives of aliphatic hydrocarbon having 1-4 carbon atoms.  The reduction of the content of aromatics and nitrogen compounds may be effected by destroying them by catalytic hydrogenation, e.g. with a cobalt molybdate-alumina or similar catalyst. Alternatively they may be removed by a method in which they may later be recovered, for example by solvent extraction, e.g. with furfural, sulphur dioxide, or a glycol, washing with sulphuric acid, urea adduction, or adsorption, for example on silica gel or a 5<\>rA or 13<\>rA molecular sieve.  Specifications 928,460, 942,237 and 943,938 are referred to.

Abstract: 1536200 A rocket catapult TALLEY INDYSTRIES OF ARIZONA Inc 2 March 1976 [5 March 1975] 08328/76 Heading F3C An ejector seat or crew-containing capsule is propelled by a rocket catapult comprising a catapult tube 11 (Fig. 2) and a telescoping rocket motor tube 10 enclosing a solid propellant 30 which is ignited by an igniter 38 mounted within the motor tube 10 and actuated mechanically by a cable 32 attached to the catapult. In operation, gas supplied to an inlet 26 at the base of the catapult tube 11 shears a holding pin 27 to force a firing pin 28 against a primer cap 24 that ignites a propellant 23. The produced gas pushes the cap support 21 downwards against a spring 22, to release tang lock fingers 14a from abutment against holding shoulders 19. The gas pressure on a plate 14 then pushes the plate and motor tube 10, held to the plate by plugs 15, upwards until plate 14 abuts against catapult tube shoulders 29. The motor tube 10 continues moving due to inertia, and shears the studs 15 at 17 from the plate 14. Cable 32, comprising stranded stainless steel having a nylon coating, is thereby tensioned, as its lower end 33 is held in the plate 14 or to the catapult tube 11. The upper end includes a metal sear 34 (Fig. 4) normally engaging a slot and aperture 45 of a firing pin 43, which is pulled by the tensioned cable 32 and sear 34 against a spring 44. As the sear clears the bottom of the igniter housing 40, it falls away over a camming surface 46, and the firing pin 43 returns to strike a primer cap 41 to ignite the particulate igniter material 35. The latter ignites the rocket propellant 30 via apertures in a plate 37, with the propellant exhausting through, and the sear and cable dropping away through, an exhaust nozzle 31 (Fig. 2). The ejector seat &c. is carried away by a lug 12. In alternative embodiments, the cable 32 breaks to allow ignition, and may pass through a booster tube to prevent contact with the propellant 30.

Abstract: 287,871. Askania-werke Akt.-Ges. vorm. Centralwerkstatt Dessau und C. Bamberg-Friedenau. March 28, 1927, [Convention date]. Aeronautical compasses.-An aircraft observer indicates the course to be followed by turning a compass casing so that by means of fluid pressure a servomotor is operated to set the pilot's direction indicator and/or automatically steer the aircraft. Compressed air of other fluid passes through passages h, i, and nozzles d, e into the compass casing and the jets enter nozzles f, g connected to a servomotor o. An eccentric disc c connected to the magnetic portion of the compass variably interferes with the jets, but when the aircraft is on the required course, the pressure in pipes m, n is equal. The observer turns the casing H through worm-gearing W, S<1>, in a direction opposite to that in which the machine is to be steered, and the consequent relative turning of the disc c operates the servomotor. Weak springs act on either side of the piston p to return the servomotor to normal. A diaphragm might replace the piston, and separate means for intensifying the power may be used. The nozzles mav be arranged in a horizontal plane, the disc c being replaced by a cylinder segment. The nozzles d, e and the pipes m, n might be continuous, valves, cocks or the like being adjusted by the setting of the casing, which may be turned electrically or hydraulically. A single nozzle or a number of nozzles may be used if required.

Filed: 1918-05-21
Abstract: 119,420. Smith, A., and Southall. C. May 21, 1918. Automatic-feed weighers. - Relates to automatic weighing-machines of the type in which the opening of the discharge door at the base of the weigh pan or hopper and the re-starting of the machine after each weighing are effected under hand control. To prevent the machine from being re-started until the discharge door has been properly closed, two lever mechanisms are arranged on the weigh pan or hopper in conjunction with the door and on the machine frame in conjunction with the driving-mechanism respectively, and a catch on the hopper under control of the first lever mechanism is adapted to obstruct the action of the second lever mechanism when the door is open. As shown, the hinged door at the base of the hopper b is operated by a link c from a bell-crank lever a, and, when the door' is closed a projection f on the lever a engages a spring controlled lever e and withdraws the catch-ba d. Two levers g, h on the machine frame are connected by a link i. The lever g actuate through a link j a shaft k which controls the main clutch of the machine. The lever h actu ates the lever a and is moved in one direction by a spring-controlled pawl m on a sliding handle bar l. Near the end of its movement, the paw engages a projection n on the handle-guide o, and is disengaged from the lever h. When the re quired weight has been delivered into the hoppe b, the machine is automatically stopped by the tilting of the weigh beam, and the attendant then slides the handle l against the action of its spring p, whereupon the lever h strikes the lever a and causes the door to be opened, the bar d preventing the return of the lever h. Simultaneously, the shaft k is actuated and mechanism for re-start ing the driving-clutch is brought into position When the door is properly closed, the hoppe lever-mechanism withdraws the catch d and allows the lever mechanism on the frame to re turn to its original position, and during such re turn the shaft k operates the clutch and the machine is re-started.
