Title: Improvements in and relating to the production of olefinic gases from hydrocarbon oils
Inventor: WOOLCOCK JAMES WILLIAM
Filed: 1954-11-11
Abstract: Mixtures containing C2-C4 olefines having a high ethylene content and a high ethylene: propylene ratio are obtained by subjecting in a first stage, a heavy petroleum oil which cannot be completely vaporized at atmospheric pressure at 400 DEG  C. to a thermal treatment in excess of 550 DEG  C. which yields a gaseous product which is rich in saturated hydrocarbons, and in a second stage continuously feeding at least some of the hot gaseous products from the first stage together with an excess of steam heated to a higher temperature than the hot gaseous product to an isolated zone within which the mixture is confined without the supply of additional heat for a short period of time, and then continuously quenching the product from the second stage to below 500 DEG  C.  The first thermal treatment may be of the semi-continuous type with a solid fixed heat transfer medium but a continuous process is preferably used in which pebbles, balls or pellets of regular or irregular shapes from the heating medium are employed.  In the second thermal treatment the steam should be preheated to 850-950 DEG  C.  In a specific example a heavy oil which did not vaporize at 400 DEG  C. was heated to 670-720 DEG  C. on contact with 1/8 -\ba3/4 inch diameter hard petroleum coke pebbles with a contact time of 10-20 seconds.  This mixture was then mixed with 3.05 times its own weight of steam at 925 DEG  C. and then passed through a refractory-lined soaking zone, the products being quenched immediately at N.T.P.  The gaseous product comprised 40.7 per cent C2H4, 11.9 per cent C3H4 and 31.9 per cent CH6.

Title: Improvements in or relating to respirators
IPC: A62B7/04
Filed: 1948-12-20
Abstract: 663,202. Respiratory appliances. FILETI, A. Dec. 20, 1948, No. 32898/48. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 21, 1949.] Class 81 (ii) A respiratory device for supplying gas to a mask or mouthpiece comprises a casing having two chambers, each connected individually to the mouthpiece, one chamber being supplied with gas through a valve controlled in accordance with the pressure in the other chamber. In one form described a diaphragm 8<SP>1</SP>, Fig. 1, is open to the atmosphere through an orifice 9<SP>1</SP> on one side and to the mouthpiece 13, through a tube 10<SP>11</SP> and ducts 5<SP>1</SP>, 6<SP>1</SP>, on the other. Its movements are communicated by a rod 4 to a valve member 3 to control the flow of gas from a supply pipe 9, through an orifice in a plate 5 to a chamber 2<SP>1</SP> and thence through a tube 101 to the mouthpiece. Thus the flow of gas is controlled in accordance with the variations in pressure at the mouthpiece and it is not influenced by the pressure drop in the supply pipe thereto, so allowing the use of a narrower bore pipe than hitherto. The diaphragm 8<SP>1</SP> may be biassed by a leaf spring 311, adjusted by a screw 11<SP>1</SP>, and the control valve may be set slightly open, to a desired extent, by means of a plunger 6, sealed by a rubber pad 7, coacting with the valve member 3 and set by a cam surface on a hand wheel 10. In a modification the flow of gas is controlled electrically by the pressure responsive diaphragm. The diaphragm 8, Fig. 2, when bowed inwards by the user's inspiration, causes a push rod 22 to make electrical contact with a member 25 and complete a circuit through a solenoid 27 which attracts an armature 28 and this, through linkage 29, opens the supply valve 3. The contact device 25 is made with carbon granules so that the current flowing, and thus the extent of opening the valve, is proportional to the degree of suction in the chamber 1. A similar arrangement in which the control is effected pneumatically instead of electrically is described with reference to Fig. 3 (not shown); in this the power for operating the mechanism is taken from the compressed gas itself. In these two arrangements it is possible to dispense with a pressure reducing valve and to use a high pressure valve in the control mechanism. Such a valve may comprise a closed ellipse of tubing, as shown in Fig. 5, with opposed outlets tending to close each other under the distorting influence of the internal pressure. The valve is opened by exerting a lateral compressing force 48 on the sides of the ellipse.

Title: Method and apparatus for exploding combustible gaseous sub stances at atmospheric pressure
IPC: B21D26/08
Filed: 1974-07-25
Abstract: 1453989 Explosion moulding K E ARVIDSSON 25 July 1974 [3 Aug 1973] 32974/74 Heading B5A [Also in Division F3] A mixture of a combustible gaseous substance, oxygen, and particles of a combustible or explosive substance is formed in a combustion chamber 1 and is ignited to explode or detonate the mixture, e.g. for compressing porous substances such as wood which is undergoing impregnation or for moulding plastics. A string 13 of packages of explosive particles (Fig. 2 and 3, not shown) is fed from a reel 12 and the packages are separated, e.g. by peeling apart two enclosing strips 28 (Fig. 4, not shown) or by severing interconnecting portions by a knife 31. A package falls through a funnel 15 into a feed chamber 10 from where it is released into an evacuated space 9 where it bursts to its higher internal pressure. Combustible gas such as acetylene or butane and air are passed through the space 9 to mix with the released particles and carry them into chamber 1 where the mixture is exploded by an electric spark 4, a heater, or a laser beam. The chamber is surrounded by liquid 1c and is vented through a pipe 3.
Patent GB-330052-A (GB)
Abstract: 330,052. Wingfield, B. R. April 9, 1929. Fuel and air supply, regulating. - In a steam boiler plant a variation in the ratio of the flow of steam from the boiler and the flow of air to the furnace is employed to operate a valve which controls a damper or the speed of the fan supplying air to the furnace. The fuel supply may also be controlled to correspond with a change in the air supply. The steam and air flow metering devices cause cams 6, 7 respectively, Fig. 1, which move in opposite directions, to raise or lower one or other of the ends of a floating lever 1 when any change in the ratio of the steam flow to air flow occurs and actuate through a second floating lever 9 a lever 15 which controls a valve 18. This valve controls the supply of fluid pressure to a diaphragm or piston adapted to actuate a damper or a rheostat controlling the speed of a motor driving the air supply fan. The floating lever 9 is also raised or lowered by a cam 14 the position of which changes with the steam pressure in the boiler and the air-supply is varied accordingly. As shown in Fig. 2, a cam 20 driven by the air metering device actuates through a floating lever 21 a lever 30 and valve 19 which controls the supply of fluid pressure to a piston 28. The latter operates through the piston rod 27 the fuel feed control, the rod 27 being provided with an adjustable cam 26 which engages with one arm of a lever 23 upon which the floating lever 21 is pivoted and serves also to control the valve 19.

Filed: 1972-07-14
Abstract: 1403572 Measuring volume of logs photoelectrically ATMOSPHERIC SCIENCES Inc 14 July 1972 [27 July 1971] 33119/72 Heading G1A The length and volume of logs is measured using a plurality of photo-sensitive devices 1b-Kb arranged alongside a path and three arrays of similar devices 21-23, each array comprising a line of sensors very close together, preferably on a single chip, and associated with an optical system for projecting light from a suitable field of view on to the array, a measurement being obtained by passing a log 11 along the path in the direction shown by arrow 13 and causing the electrical outputs in the cells in the array 23 to be scanned each time the output from one of the cells 3b to Kb is changed by the appearance of the leading edge 11a of the log between the cell and its associated light source, and means responsive to the signals from the array and from the cells 1b-Kb for calculating required dimensions. The number of cells of the array 23 exhibiting an output corresponding to a dark or light condition is indicative of the length of the portion of the log 11 projected on to the cells, this number being counted in a counter and compared with a count indicative that all the cells of the array are covered by the image of the log, whereby when a count difference is detected, indicative that the edge of the log is within the view of array 23, the total length of the log is computed in a processing device from information regarding the particular cell 3b-Kb actuated and the count at array 23. Two further cells 1b, 2b are adapted to cause further arrays 21, 22 to be activated, the cell 2b when the leading edge 11a of the log comes into its field and the cell 1b when the trailing edge 11 b comes into its view. The arrays 21, 22 are arranged to scan the log in directions perpendicular to its motion and at mutually perpendicular directions, whereby measurements of the average diameter of the log may be made near each end of the log and the volume of the log calculated therefrom. The arrangement of arrays is said to compensate for errors owing to lateral movement of the log in its motion, (theory in Specification).

Title: Improvements in or relating to non-metallic resistors and methods of making them
IPC: H05B3/14
Filed: 1931-11-30
Abstract: <PICT:0393283/III/1> A silicon carbide resistor is made of grains having a silicon carbide content of 99 per cent or greater.  In order to purify the grain, crude lump silicon carbide is crushed and treated with an acid, such as sulphuric acid, to remove surface impurities.  For further purification, the grain may be treated with a solution of sodium hydroxide or other alkali.  In an example, 32,5 per cent of 120-mesh silicon carbide, acid and alkali washed, is mixed with 65 per cent of 280-mesh silicon carbide powder, acid and alkali washed, and 2,5 per cent of lamp-black.  The grain is mixed with a temporary binder such as sodium silicate, moulded, and given a preliminary baking at 600 DEG  C.  The resistors are then removed from the mould and dipped in a slip or slurry containing fine sand, carbon, and water.  The coated resistors 4 are placed in a furnace consisting of a refractory bottom 1 covered to a depth of about two inches with a mixture 3 of fine silica and carbon in the proportion of three parts of silica to one part of carbon.  The resistors 4 are placed end to end between electrodes 2, and joined by means of graphite blocks 5 and a paste of graphite, silicon, and sodium silicate.  The resistors are then covered with a further layer of silica and carbon mixture and current is passed between the electrodes 2, a temperature of about 2000 DEG  C. or 2200 DEG  C. being attained.  The sodium silicate employed as a temporary binder is decomposed, and vaporization of the silicon carbide takes place, causing recrystallization which binds the particles together into a strong coherent mass.
