Title: Improvements in the treatment of materials containing sulphides
IPC: C01B17/06
Filed: 1952-03-25
Abstract: Materials containing iron sulphides are subjected in the absence or presence of a combustible carbonaceous substance to such a degree of oxidizing conditions that only a partial oxidation of the fixed sulphide content is effected and the temperature controlled below the melting point of the remaining sulphide or subsulphides to promote their reaction with the sulphur dioxide formed to produce sulphur so that together with such sulphur as the sulphides yield directly by thermal dissociation, a high proportion of the sulphur content is evolved in elemental form without any of the other reaction products being fused, slagged, sintered or melted.  The process may be performed in a fluidized bed or in a reaction chamber in which the charge moves through the chamber in counterflow to the gas passing over or through it.  The conditions are such that about 20-40 per cent. of the total sulphide content is oxidized, depending upon the ore used, and a temperature of up to 980 DEG C. is stated to be satisfactory for a fluidized bed, reduction of sulphur dioxides by the sulphides present being sufficiently rapidly completed at 800-950 DEG C. in a chamber of economic size.  The resulting ferroso-ferric oxide may be reduced to metal by means of a carbonaceous reducing substance or oxidized to ferric oxide (e.g. in the case of auriferous pyrites, for cyanidation) in a further separate treatment, e.g. in a fluidized bed.  Sulphur may be recovered as solid or liquid by passing the sulphur-containing exit gases through a cyclone and electrostatic precipitator, both operating above the boiling point of sulphur to remove entrained magnetite dust, and then to an electrostatic precipitator operating below the boiling point of sulphur, when sulphur is removed from the gases.ALSO:Magnetite produced from material containing iron sulphide (see Group III) may be fluidized with air or a reducing gas or both and reduced to sponge iron by means of a carbonaceous reducing substance at 850-1000 DEG C.

Title: Clip-loading cap gun
Inventor: MOE WALTER
IPC: F41C3/08
Filed: 1967-02-17
Abstract: 1,138,647. Toy gun. IDEAL TOY CORP. 17 Feb., 1967, No. 7680/67. Heading A6S. A clip-loading cap gun comprises a gun body 12 shaped to receive internally a removable clip 14 which contains cap storage and cap advancement and firing means the clip preferably being received in a cavity in the handle of the gun. A sheet metal cover is pivoted to the cart clip body at 48 providing access to cap storage area 50 in which a roll of caps R is mounted on cylindrical post 54, a strip of caps S being threaded between the dividing wall 51 and the rear wall 42 of the clip body 36. The cap firing and advancement means comprises, pivotally mounted on post 60, an actuating lever 58 the contact face 62 of which is engaged by the firing extension 32 of the trigger 22 when the trigger is moved into its firing position. Hammer lever 64, with a hammer face 66 at its upper end, also pivots about post 60 and is biased toward its rearward position against the anvil 56 by firing spring 68. The actuating lever 58 may move transversely within opening 74 formed in the lever and on pulling trigger 22 (see Figs. 9 and 10) the lever eventually moves upwardly when camming wall 76 engages a camming post 78 on the clip body causing cocking tooth 70 to disengage hammer tooth 72 thereby releasing hammer lever 64 to explode a cap against anvil 56. The strip S of caps advances with each firing by means of the advancement link 80 pivoted to the actuating lever 58 and 82, the coil spring 84 biasing both link 90 and lever 58 downwardly, lug 90 preventing link 80 from pivoting too far downwardly. The clip 14 is secured in the cavity 34 by means of a latching lug 94, on the rear wall 42, which engages a camming latch 96 mounted within the gun body 12, the latch unlocking to release the clip on depression of the latch button 104 against the bias of force spring 100. (see Fig. 5).

Abstract: 270,465. Torrance, J. R. March 25. 1926. Roller mills.-In roller mills for grinding paints, enamels, inks, &c. and of the kind in which the material is caused to travel from the feed end to the delivery end of the grinding unit, the fast roller is of relatively large diameter compared with the slow roller. Figs. 1 and 2 show a mill with tapered rolls 1, 2 mounted on parallel spindles 3, 4, the large end of one roll being opposite the small end of the other roll. The diameters of the rolls 1, 2 are the same at the feed end of the mill, the slow roll 2 tapering down to about half its larger diameter at the small end. The larger and fast roll 1 takes the paste from the surface of the slow roll and feeds it from the small end to the large end of the roll 1. The feed-hopper 5 at the small end of the roll 1 mav be adjustable and about one-quarter of the length of the roll, and the delivery scraper 6, in spring contact with the roll 1 at its larger end, may be about one quarter of the length of the roll, or less. Directional guides 7, 8 may be provided at each end of the hopper 5 to direct the material to the grinding region of the rolls, and the rolls may be provided with pressure springs as described in Specification 218,752. Fig. 3 shows a mill with parallel rolls 9, 10 and spaced inclined directional guides or doctors 13 bearing on the top of the fast roll 9 and pivotally mounted so as to be adjustable. A scraper may be set near the nip of the rollers to remove the material. The directional guides may be used with the mill shown in Figs. 1 and 2.

The fingers 12 are each supported by a respective parallelogram linkage 22, 24, 27 and 23, 25, 28. The adhesive tape 14 is drawn from a reel 29 by reciprocating grippers 21 which are movable through the openings 13 in the fingers 12. Lengths of non-adhesive strip 31 are applied to the adhesive tape 14 at spaced intervals and a cutter 20 is arranged to cut through the middle of a non-adhesive strip length on the tape 14 as the tape is clamped around the gathered bag end. A printing device may print on the adhesive tape 14. The open end of each bag is flattened by rotating brushes 1, 2 prior to being delivered between the guides 7, 8 by a pair of belts 5, 6. The bags may be carried on a conveyer belt during movement of their open ends through the machine.

The orifices (Fig. 3) comprise an outlet portion at least 0,045 inch in length (b) and about 0,018 inch in diameter (a), and an inlet portion defined by conical walls having an angle of taper of about 15 degrees, and a diameter (c) of about 0,035 inch.  Preferably, the orifices in each row are spaced an equal distance apart.  The spinneret may be cup-shaped, conical or plate-type and may be made from any material which is not corroded by the collagen dispersions, e.g. nickel, platinum, silver, plastic or glass.  In one embodiment (Fig. 2) the spinneret has 197 orifices, in 8 concentric circular rows, and satisfies the relationship A1/A2 =4,913 where A1 is the area defined by the outermost row of orifices and A2 is the total outlet area of all the orifices.  Using this spinneret, a 1% dispersion of collagen fibrils in perfluorbutyric acid may be extruded into a circulating acetone dehydrating bath with no breaks or featherformation over an 8-hour period.

Abstract: 401,171. Fuel-injection pumps. L'ORANGE, H., 19, Feuerbacherweg, Stuttgart, Germany, and SIMMS MOTOR UNITS, Ltd., Percy Buildings, Gresse Street, Rathbone Place, London. March 20, 1933, No. 8412. Convention date, April 27, 1932. [Class 102 (i).] In a fuel-injection pump an annular suction valve 13, Fig. 1, is employed concentric with the plunger. The valve seats on the end of the cylinder liner 3 and controls suction passages 15, which communicate with an annular suction recess 17. The latter communicates also with a recess 19 having a helical edge 20 co-operating with passages 21, 22 in the plunger to effect the spill. A leakage-collecting space 24 communicates with the space 17 by means of passages 25. In a modification, Fig. 2, the suction valve 13 seats on the head of the compression chamber and controls passages 15a communicating with an annular recess 28 formed between the head 10 and a ring 29 fitting on the head and carrying the inlet pipe 18a. The spill is controlled by a helical edge 20a on the plunger co-operating with passages 22a, 16a to effect discharge of the spill to a recess 17a and passage 27. Alternatively the output may be regulated by varying the stroke of the plunger.
