Title: Method and apparatus for magnetic concentration of particulate material
IPC: B03C1/03
Filed: 1961-01-11
Abstract: 963,746. Magnetic separators. D. WESTON. Jan. 11, 1961 [Dec. 23, 1960], No. 1240/61. Heading B2J. Continuous separation of particulate material, such as lowgrade iron ore, of different magnetic susceptibilities is effected by feeding the material in an elongated shoot which is traversed continually by a series of longitudinally spaced magnets the opposite poles of which embrace the shoot so as to produce a magnetic flux across the entire cross-section thereof and magnetic gradients along the length thereof whereby the more strongly magnetic particles are concentrated and collected separately from the weaker particles. Figs. 5 and 6 show the shoot as a hollow non-magnetic ring 20 of rectangular cross-section which is twice as deep as it is wide, with a series of electromagnets 36 circumferentially spaced around the periphery of a wheel 38 mounted for rotation about the axis of the ring 20 so that the poles of the magnets lie close to the opposite sides respectively of the ring section. The shoot is supported on legs 21, 22 and material is fed into the shoot via a duct 27 to fall in a direction (counter-clockwise) opposite to the direction of movement of the magnets 36. In operation, the magnets adjacent the feed duct collect the more strongly magnetic particles and any which are not so collected are caught up by the succeeding magnets traversing the recovery path of the shoot, the tailings being exhausted by a fan or pump 31 from a receiving portion 28 at the lower end of the shoot. The magnetic concentrate is thus carried around the shoot and is collected at the lower portion 29 thereof which is blocked off from the portion 28. The energization of the magnets may be interrupted as they reach the top of the shoot to facilitate recovery of the concentrate, and baffles 34a, together with circumferentially spaced water inlets 32-35 may be provided in the shoot to clean and wash the concentrate. A fibre-glass paddle wheel may be rotated in the shoot portion 29 for positive discharge of the concentrate. The magnets 36 may be arranged either with like poles on the same side of the shoot or with their poles alternating around each side of the shoot. In an alternative arrangement, Fig. 11, the outer periphery of the shoot, together with the feed and water inlets and collecting portions may be supported to form a stationary cover 105 sealed to a circular channel 100 which is fixed to the poles of the magnets 112 for rotation therewith. In further arrangements, the shoot may be of inverted-U- form with the recovery path vertical, Fig. 2, or horizontal, Fig. 3, the magnets being carried on an endless chain 11. If desired, the magnets may be moved in the same direction as material feed rather than counter thereto. Magnetic field intensities up to 35,000 gauss may be used, and heat dissipating means may be associated with the magnets.

Title: Improved process for converting heavy hydrocarbon oils into lighter hydrocarbon oils
Filed: 1922-01-14
Abstract: 174,089. Standard Oil Co. Jan. 15, 1921, [Convention date]. Hydrocarbons, cracking.-Hydrocarbon oils, such as heavy Mexican crude petroleum, are subjected to a heat treatment so that on subsequent distillation a large yield of low-boiling products is obtained. The oil is fed by a pump 1 through a heat exchanger 3 and a furnace-heated pipe 5 at such a speed that on leaving the pipe 5 it has a temperature of about 800‹ F., and that there is no substantial deposition of carbon in the pipe. The velocity of the oil may be varied while maintaining the tamperature of the outgoing oil by varying the temperature of the furnace and the rate of feed of the oil, and may be increased by injecting through a valve 6, steam, water, oil gas, flue gas, &c. or by adding low-boiling fractions to the crude oil. The oil passes from the pipe 5 to drums 7, 7<1> used alternately and heated to about 900‹ F. preferably by the waste gases from the furnace heating the pipe 5. Copious coke deposits are formed in the drums. The oil is led away by a pipe 8 to the heat-exchanger 3 and thence through a valve 9 to cooling and storage chambers or to stills. The valve 9 maintains sufficient pressure in the apparatus to prevent vaporization of the constituents of the oil.

Title: Improved method and apparatus for the manufacture of fusible metal caps
IPC: B23K35/02
Filed: 1955-01-18
Abstract: 763,767. Making fusible caps for stud soldering; blank punching; stamping. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Jan. 18, 1955 [May 14, 1954], No. 1459/55. Classes 83 (2) and 83 (4). [Also in Group XVIII] In making a fusible metal cap for frictionally fitting to the end of a metal stud &c. to be electric arc stud soldered, a circular disc of fusible metal is formed into a bowl having a cylindrical wall, flux is inserted into the bowl, a second smaller disc of fusible metal is fitted in the bowl to cover the flux and axial indents are formed in the wall to retain the second disc in position. In an embodiment a series of dies 10 are provided in a table 2 intermittently rotatable beneath a series of units A-G stationary parts of which are mounted on a base 1 and upper movable parts of which are mounted on a slide 4 which is vertically reciprocated when the table is stationary. The unit A comprises a die 6, Fig. 3, above one of the dies 10 in the table 2, having a guide 7 for the feed of a strip 8 of silver solder, copper solder (a copper phosphorus alloy) or welding bronze (copper zinc alloy with nickel lead or tin) and a punch 9 which on downward movement of the slide 4 to which it is attached cuts a circular disc from the strip and ejects it from the die 6 to fall into a cavity 13 in the die 10. The table is moved one step to locate the die 10 beneath unit B which comprises a spring- pressed member 16, Fig. 4, to hold the disc in the die 10 while a punch 15 engages the disc to form it into a bowl 17 with a cylindrical wall, the member 16 and punch 15 being attached to slide 4. The table is moved another step and the bowl is located beneath the unit C which includes means for delivering a measured quantity of alkaline metal chloride, fluoride or borate flux into the bowl. With the bowl beneath unit D which is similar to unit A a disc of fusible metal is punched from a strip to fall into the bowl to cover the flux. In the next position beneath the unit E a punch presses the second disc into the bowl. A further table movement brings the bowl beneath the unit F where a punch 31, Fig. 8, attached to the slide 4 forces the bowl through the lower part of the die 10 provided with axial ridges to corrugate the cylindrical wall and ejects the cap from the table. A unit G comprises a brush 34 for cleaning the bore of the die 10. In a modification the table may be replaced by an endless conveyer belt. Instead of corrugating the cylindrical wall, three single spaced indents may be provided. The finished cap, Fig. 8a, is fitted to a stud and retained thereon by frictional engagement of the corrugations on the stud.

Filed: 1937-01-19
Abstract: 494,328. Regulating steam and air supply to furnaces. SEROG, H. Jan. 19, 1937, Nos. 1576 and 1577. Void. Convention dates, Jan. 21, 1936 and Jan. 11, 1937, [Class 51 (i)] In a locomotive boiler furnace a nozzle 13, Fig. 3, delivers high pressure steam to the firebox when the locomotive is running and low pressure steam when the locomotive is stationary. An air damper 20 controlled by the firedoor admits air to the passage 26 surrounding the steam nozzle. When the locomotive is running, steam passes from the slide valve chest through a pipe 7, Fig. 2, to a chamber 9a and thence through a passage 3a to a chamber 8a where it raises a piston 8 and valve 10. High pressure steam from the pipe 1 then flows through the chamber 2 into the chamber 5, through the non-return valve 12, Fig. 3, into chamber 6a, and to the nozzle 13. The piston 9 in the chamber 9a is also raised and closes the valve 11. When the locomotive is at rest, the pistons 8 and 9 fall, valve 10 is closed and valve 11 is opened. Steam then passes from the chamber 2 through the passage 3 and past a hand operated pressure reducing valve 18 to the chambers 4a, 6 and thence to the chamber 6a and to the steam nozzle 13. Steam also passes through a pipe 15 to the smoke box blower. The air damper 20 is mounted on a spindle provided with a crank arm connected to a lever 34 which engages with an arm 36 secured to a rod 38 which is actuated by closing the firedoor. As the firedoor is closed after stoking, a cam 51, Fig. 5, on the door spindle 52 engages with a pivoted pawl 47 provided with a pin 46 adapted to engage with a hooked member 45 on the rod 38 which is pushed to the left and actuates the air inlet damper as well as a dashpot piston 41. The damper closes gradually under the control of the dashpot.
