Abstract: 655,957. Washing coal. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. March 13, 1948, No. 7710. Convention date, March 14, 1947. [Class 82(ii)] In a method of washing coal using a cyclone, the fractions leaving both base and apex of the cyclone are sieved to remove large particles of coal and stone respectively and the remaining suspension returned to the cyclone after the finest particles of coal have been removed by froth flotation. An installation for carrying out the above method comprises a cyclone 1, into which the coal to be washed is fed as a suspension at 2, the coal 3 being fed on to a sieve 6 and the stones 4 fed on to a sieve 5. The small particles of low specific gravity, which are drained from the coal into the collecting tank 21, are conducted by pipe 20 and sprayed on to the stones fraction. Both coal and stones fractions are then sprayed with water at 8 and 9, and the small stone particles from the collecting tank of sieve 5 and small coal particles from collecting tank of sieve 6 are conducted by pipes 12, 13 to the froth flotation machine 14, the small particles of coal then being carried off with the froth at 15 and the small particles of stone taken out by pipe 16 via a pump 17 back to the cyclone. The coal to be cleaned is fed into a tank 18 and is also pumped via pipe 16. The concentration of the solids removed from the froth flotation machine can be varied by varying the level of the outlet 19. Alternatively the outflow 12 from the sieve 5 may be arranged to pass at 12<SP>1</SP> into the flotation tank outlet 16. The specific gravity of liquid may also be varied by varying the relative quantity of rinsing waters at 8, 9 the total quantity remaining the same.

Abstract: 728,139. Welding by pressure; shearing. GENERAL ELECTRIC CO., Ltd., and SOWTER, A. B. March 13, 1953 [March 26, 1952], No. 7773/52. Class 83 (4). In apparatus for cold pressure welding pairs of wires &c. a pair of holders capable of rectilinear movement each has a set of jaws with a bore for holding a wire and having a tapered external shape co-operating with a similarly shaped aperture in the holder so that movement of the jaws in one sense effects clamping of the wire. In an embodiment of a handoperated tool two levers 3, 4 are pivoted together at 18 and are pivoted at 8 and 17 respectively to a fixed block 1 and to a thrust member 11. The member 11 is pivoted at 10 between two arms 9 projecting from the block 1. A pair of rails 15 secured to the block 1 slidably support a movable block 2 resiliently held against two thrust pads 13 on the member 11 by an arm 19 pivoted also at 10 and acted on by a spring 6. A pair of jaws of the form shown in Fig. 12 are slidably mounted in slots 31, 32 in the blocks 1, 2 and are retained by plates 24. Each jaw member 25 carries a pin 33 engaging in a recess parallel to the sides of the slots 31, 32 and in the base thereof. Jaw release members 35, 37 which gang the jaw members together are provided for the sets of jaws in the blocks 1, 2 respectively. Each member 35, 37 comprises an arm having slots which engage the pins 33 and are spring urged to close the jaws. Pressure applied to the levers 3, 4 against the force of springs 5, 6 rotates the member 11 about its pivot 10 and the thrust pads 13 move the block 2 along the rails 15 towards the block 1. A cutting device 41 provided to trim the ends of the wires before welding comprises a pair of connected side plates 42, 43, Fig. 6, having grooves 55 for the wire ends and spaced by blocks 46, 47, within which slide cutting blades 44, 45 as shown in Fig. 7. A pin on an eccentric 53 operated by a knob 50 through a tommy bar 51, engages in slots 56, 57 in the blades and side plates respectively. With the device 41 in its normal lowered position the knob 50 is turned to raise the device until a spring urged plunger 59 enters a recess 58 in spacing block 46. Continued turning of knob 50 raises the blades relative to the side plates. Wires are fed into the jaws and the latter are brought up to the device 41 by operation of levers 3, 4. With the wire ends in the grooves 55 the knob 50 is turned to lower the cutting blades and trim the wire ends. The plunger 59 is released, the knob turned to lower the device 41 and the handles 3, 4 are brought together to effect welding of the trimmed ends. The tool may be mounted on a support bolted to one of the arms 9 of the block 1. Two bench type tools operated by a single hand-operated lever and having fixed and moving holders for pairs of jaws similar to those referred to above are described, and having an end trimming device. The rods may be operated in an inert atmosphere of e.g. argon. Specification 689,927 is referred to.

Title: Improvements in or relating to steam irons
IPC: D06F75/16
Filed: 1948-03-16
Abstract: 648,928. Hand-irons. NATIONAL PRESSURE COOKER CO. March 16, 1948, No. 7912. [Class 138 (ii)] In a steam iron having a sole-plate 3 provided with an opening 69, heating means 7, a boiler 25 for water, and passageways for conducting steam from the boiler to the sole-plate and to the material to be pressed, the boiler being disposed in spaced relation with respect to the heating means, the water in the boiler is heated to steam by a metallic hollow heat-conducting chamber 53 which is in heat-conducting relation with the heating means and which extends upwardly through the boiler from the opening 69. The amount of heat passing from the heating means directly to the base 43 of the boiler is limited by insulation or an air space 55. The chamber .53 also acts to superheat the steam. Steam generated in the boiler 25 enters the chamber 53 through passageways 103, 101 in a removable cap 95, and leaves by way of an aperture 83 in a pipe 79 mounted in a plug 73. It is then discharged through one or more openings 89 in a cup-shaped member 87 pressed into the opening 63, to the material underneath the iron and also to a forwardly-extending channel 91. Any drops of water collecting at the bottom of the chamber are broken up by means of an atomizer comprising a vertical tube 105 extending nearly to the base of the chamber and communicating at the top with a nozzle 107 adjacent and at right angles to the steam inlet passage 101. A heat conducting spacer ring 71 co-operates with plug 73 and the chamber 53 to hold the sole-plate 3 and the base 43 of the boiler in spaced relation and chamber 53 may be welded to the base 43. A baffle member 108 forming a pocket 109 collects most of the water to the rear of it if the front end of the iron is tipped downwardly, thereby preventing the remaining volume of water rising high enough to enter passageways 103. A heat indicator 19 has a dial 21 and pointer 23 positioned at the top of the handle and a knob 15 controls the setting of a thermostat 13. Water is supplied to the boiler through a filler tube 29 having at its upper end depending flanges 39 adapted to be engaged by lugs 37 carried on a closuremember 33. Fig. 3 shows a modified form of superheater chamber dispensing with the atomizer and with the plug 73. Steam enters through passageways 103a, 101a and leaves through a tubular conduit 79a which extends upwardly into a recess 72 in a cap 95a. An integral flange 67a of chamber 53a is welded to bottom wall 43a of the boiler and holds the boiler and sole-plate in spaced relation by means of screws 70. In Fig. 4 (not shown) the inlet passageway 101 of Fig. 1 has a tube connected to it and leading nearly to the bottom of the chamber and the outlet pipe leads to passageways arranged at right angles to one another in the plug, where the steam is further heated. In Fig. 5 (not shown) a channel is formed in the upper surface of the screw plug to provide additional surface area for transmitting heat to any water trapped thereon, and the inlet pipe discharges into this channel.
