Title: Improvements in methods of recovering tin
IPC: C22B25/06
Filed: 1934-01-05
Abstract: In the treatment of tin-bearing materials containing iron, the tin and iron in the form of an alloy are treated with chlorine gas and simultaneously or subsequently with oxygen at a final temperature above 114 DEG  C., say up to 300 DEG  C., at which stannic chloride is volatile and ferric chloride dissociates whereby stannic chloride is formed and volatilized and ferric oxide remains with the residue. A preformed alloy such as hardhead may be used as initial material, or an oxidic material containing tin and sufficient iron to form an alloy with all the tin may be granulated and reduced while being agitated, a large amount of inert material preferably being provided to aid in separating the alloy particles.  Reduction may be effected in a rotary furnace at say 600--900 DEG  C., with a countercurrent flow of reducing gas, and, prior to chlorination, the alloy may be fuzed and passed through a cooling fluid such as water to obtain it in a finely divided state.  Chlorination may be effected in a rotary furnace using a countercurrent flow of gas, and the volatilized stannic chloride may be condensed to give a chloride solution in a leaching tower in which water is caused to flow from one to another of a series of horizontal trays.  Specification 159,071, [Class 1 (iii)], is referred to.

Title: Improvements in or relating to spring winding machines
IPC: B21F3/04
Filed: 1938-01-07
Abstract: 503,160. Making springs. TORRINGTON MANUFACTURING CO. Jan. 7, 1938, No. 530. Convention date, Oct. 29, 1937. [Classes 83 (ii) and 83 (iv)] In a spring-coiling machine a cam is adjustably geared to a coiling spindle to impart thereto a predetermined number of revolutions in either direction for each rotation of the cam. Coiling. The coiling spindle 10 is rotated from a gear 5<111> through a toothed quadrant 23 pivoted on a pin 24 and bearing a slot 28 in which is mounted a block 31 adjustable by a screw 37 in a slot 32 in a lever 33 pivoted on a pin 34. The free end of the lever carries a stud 35 engaging a cam 26 on a shaft 27. Rotation of the screw varies the amplitude of movement of the segment 23 and determines the length of spring. To reverse the direction of coiling a gear, Fig. 14, not shown, is mounted to mesh with gears 5<1>, 5<111>. Pitch control. The spindle 10 is carried in a head 2 reciprocated by a lever 6. Initial positioning of the spindle is determined by adjustment of a screw 47. The free end of the lever is carried on a pin 50. A roll 52 engages a slot 54 in a pitch cam 55 mounted on a stud 56 on a pitch control slide 57. Oscillatory movement of the cam 26 through a rod 62 reciprocates the slide 57, the cam 55 is set at an angle to the slot 54 and moves the lever 6 and spindle head 2 to determine the pitch. To vary the pitch the cam 55 is adjusted about the pivot 56 on the slide 57. Feed. A shaft 71 driven by the shaft 27 carries a cam 80 reciprocating a slide 81 connected to an arm 83, on a bracket 85 surrounding a feed roll shaft 86, and carrying a slot 87 engaged by a block 90 on a segment 93 with teeth 94 engaging a pinion or the feed-roll shaft. Movement of the segment 93 and the feed rolls 8 is effected by the cam 80. Adjustment of the block 90 by a screw 99 varies the throw of the segment 93 and the rotation of the feed rolls for a given rotation of the arm 83 by the cam 80. A cam 109 causes the feed rolls 8 to engage the wire with sufficient pressure for feeding, prior to the movement of the rolls by the segment 93. Severing and tail bending. Reciprocating tools, Fig. 11, not shown, are actuated by a cam to sever the end of the spring and to bend the tail portion. Stripping. A cam on the shaft 71 lowers a stripping finger 14, Fig. 12, not shown, and moves it to strip the completed spring from the spindle 10. Operation. Rotation of the shaft 27 and the cam shaft 71 causes rolls 8 to grip the wire and feed a length to the spindle. The segment 23 rotates the spindle and moves the spindle head laterally to wind the spring. Cams then operate the shearing and the bonding tools. The segment 23 returns to the at rest position and restores the spindle and strips the spring. Specification 492,580 is referred to.

Filed: 1947-01-09
Abstract: 627,068. Electrostatic precipitation. WHESSOE, Ltd., and PUTTICK, A. Jan. 9, 1947, No. 779. [Class 39 (i)] In an electrostatic precipitator of the two-field type having a parallel plate type precipitating zone, discharging electrodes are provided in the precipitating zone at or adjacent the edges of the high-tension plates of that zone, which extend in the direction of gas flow, to reduce the loss of precipitating efficiency at the edges of the zone. The discharging electrodes 9a, Fig. 3, adjacent to the edges of precipitating plates 10a, are extensions of the discharge electrodes 9 of the ionizing zones. The earthed plates 8 form internal partitions of the earthed casing 5. In another embodiment, Fig. 1 (not shown), the discharge in the precipitating zone is effected by forming serrated edges on the precipitating plates which may be plane or corrugated, and any plates which do not form part of the outer casing of the precipitator may be formed of mesh or by a series of strips or rods.
