Title: Improvements in the recovery of sulphur from sulphur ores
IPC: C01B17/027
Filed: 1930-08-11
Abstract: <PICT:0360899/III/1> <PICT:0360899/III/2> The recovery of sulphur and asphalt from poor ores and similar materials, particularly those containing less than 30 per cent, is effected by melting out the sulphur or asphalt therefrom, preferably by steam under pressure, and bringing the sulphur or asphalt into contact with a solution of chemicals which separates dust-like impurities therefrom.  In the apparatus shown in Fig. 1, the ore is contained in a cylindrical cast-iron tank a formed with a hemispherical base b provided with double walls constituting a steam jacket c.  The material to be treated is supported in the cylinder on a perforated plate j and steam is delivered from a pipe m formed with a perforated end r and controlled by a three-way cock n.  In a modification, Fig. 2, the perforated end is omitted and agitation effected by a stirrer s. The liquid may either be contained below the grating or fill the cylinder so that the sulphur or asphalt is either melted above the surface of the liquid or comes into contact therewith at once. Steam for the jacket is supplied by a pipe o and after removal of the sulphur or asphalt, the gangue is blown out through a valved pipe l.  The purifying solution contains sodium silicate, slaked lime, borax, common salt and magnesium chloride.  In operation, when dealing with sulphur, the tank a is nearly filled with broken ore &c. and the purifying solution, and steam is admitted, at a pressure of 50 to 65 pounds through pipes o, q, thereby boiling the solution, melting the sulphur and causing the finely divided impurities to rise to the top of the liquid.  After a period of from 15 to 30 minutes the three-way cock n is turned to the position shown in Fig. 2 thus closing the pipe q and allowing the sulphur to settle and flow out.  When the colour changes from yellow to greenish, the cock n is turned back to the position of Fig. 1 and after a short time sulphur is again withdrawn.  If still greenish, the operation is finished and the cock n is turned to the position of Fig. 1, the valve l opened and gangue is blown out.  After this is effected, the pipe q is closed, the valve p nearly shut and the apparatus recharged.

Abstract: 681,947. Rock drills. LICHTBLAU, W. Oct. 3, 1950, No. 24151/50. Class 124. [Also in Group XXII] In a feeder device for a rock drill carried by a slide shiftable on a guide, the slide is attached to a cable made wholly or partly of rubber or rubber-like material, e.g. partly of rubber cords and partly of steel cable. As shown in Fig. 1, the ends of a rubber cable 25 are attached to a tensioning and winding- on drum 2 rotatable by a lever 1 and a ratchet gear 3, the surface of the drum being formed by loose rings to prevent binding. The cable then passes over pulleys 24 independently rotatable on a drum 6, return pulleys 26 on a frame 12, vertically adjustable guide pulleys 7 and an inclined pulley 8. The pulleys 7, 8 are mounted on a slide 4 shiftable on two guide rods 9 connected to the drum 6 and frame 12 and provided with braces 17. The drill is withdrawn by means of a torsion spring within the drum 6 and a steel cable 5 connected to the slide 4 and wound on the drum 6.

Title: Improvements in vehicles for transporting material in bulk
IPC: B65G53/24
Filed: 1958-07-30
Abstract: 839,173. Pneumatic conveyers on vehicles. DANSMIDTH CORPORATION. July 30, 1958 [July 30, 1957], No. 24566/58. Class 78 (4). A blower 39 on a vehicle can be connected through a dust collector 32 to apply suction to draw material into chambers 13, 14, 15 for loading and can also be connected to deliver air to the chambers 13, 14, 15 to discharge material to a pipe 25. To load the vehicle illustrated valves are set so that the blower draws air through a conduit 36 from a cyclone separator 32 which is connected by pipes 34, 47 to draw air from one side of a baffle 21 mounted in an inverted channel 20 extending along the tops of the chambers 13, 14, 15. The other side of the channel 20 is connected to a pipe 30 terminating in a coupling by which it can be connected to a hose for the material to be loaded. Under these conditions the blower 39 discharges to the atmosphere through a silencer 44 and vent pipe 51. To unload material from the chambers 13, 14, 15 the blower delivers air through a valve 46 to the pipe 47 which is isolated from the conduit 34 by a valve 48. The air is thus delivered to the channel 20 where it applies pressure to the chambers 13, 14, 15, escaping from these chambers to a passage 22 leading through a valve 24 to a delivery pipe 25 receiving material from the chambers 13, 14, 15 through valves 27, 28, 29 and connected by a hose to a receiving hopper. Air is extracted from the receiving hopper by a further hose connected to the conduit 34 so that the air passes through the separator 32 and conduit 36 to the blower 39. The chambers 13, 14, 15 may be separated by partitions 16, 18 extending for only part of the height of the chambers, as shown, or may be isolated entirely from one another apart from the connections provided by the channel 21. Apertures 13b, 14b, 15b are provided for loading the chambers directly. A valve 35 is provided for emptying the separator 32.

Abstract: 1,260,555. Moulding nozzles. STOECKER & KUNZ G.m.b.H. 14 May, 1969 [15 May, 1968], No. 24616/69. Heading B5A. [Also in Division F4] A one-piece refractory pouring nozzle consisting of a portion 1 of wear resistant material and a portion 2 of thermally insulating material is formed by simultaneously pressure moulding the two materials in a common mould and thereafter firing the so formed composite moulding. In the case of large differences in the expansion and contraction rates between the wear-resistant and insulating materials, a length of tubing 5, Fig. 4, of combustible material may be moulded into the nozzle between the portions 1 and 2, the tubing leaving a cavity between the portions after having been burnt away. In alternative constructions (Figs. 5-8, not shown), the upper part (6) of the nozzle consists of wear-resistant material and the lower part (7) of insulating material (see Figs. 5 and 6), or vice versa (see Figs. 7 and 8). The wear-resistant material may be magnesite and the insulating material may have a basis of chrome magnesite, chromite or forsterite. Alternatively the wear resistant material may be highly aluminous, e.g. bauxite, corundum and the insulating material may be based on chamotte (fire clay).

A glass tube 1 has sealed through its lower extremity a platinum wire 2 which is silver plated, the silver plating being subsequently covered by a film of silver chloride. The wire 2 is welded to a connection wire 3 which is sealed into the upper end of the tube 1. The glass membrane 4 consists of a bulb blown from special semi-conducting glass and formed into a neck 5, or this neck may be of ordinary glass joined to the special glass. The glass tube 1 and the membrane 4 are inserted into apertures in a rubber body 6 into a cavity 8 in which a solution of, for example, decinormal hydrochloric acid has previously been poured. The silver plated wire may be replaced by a small glass tube constituting a calomel half-cell and containing mercury, mercurous chloride, and potassium chloride absorbed in asbestos shredding. The body 6 may be large enough to carry other elements, such as the other electrode and a resistance thermometer.
