Title: Improvements relating to methods of separating platinum metals from mattes
IPC: C22B23/02
Filed: 1934-11-19
Abstract: Platinum metals are separated from mattes such as nickel-copper mattes by the addition of a solid non-metallic segreating agent to the molten matte, allowing the matte to form two layers and separating the two layers before, during or after cooling of the matte.  The segregating agent may be silicon, phosphorus, or boron, or alloys or compounds thereof and such agent may be incorporated with or used in conjunction with a diluent or blending agent; for instance, ferro-silicon or phosphor-copper may be employed.  The segregating agent is preferably added in a ladle as the matte is poured from a converter in which it is blown, the temperature of the matte being between 1100 and 1400 DEG  C. Specification 316,063, [Class 82 (i)], is referred to.

Abstract: 1411349 Linkworks; ratchet mechanism SUWA SEIKOSHA KK and SHINSHU SEIKI KK 12 July 1973 [14 July 1972] 33306/73 Headings F2K and F2Q [Also in Division B6] A printing machine indexing mechanism for intermittently rotatably advancing in steps a paper feed roller 14 which is arranged to feed print paper 3 between a print drum 4 and an inked ribbon 2, a line printing operation being performed by a hammer 1, comprises a plate 8 longitudinally slidably mounted on pins 16, 17 and carrying a rack lever 26 pivotably mounted at 27 on plate 8, which plate 8 also pivotally carries at pin 11 a ratchet finger 10 spring biased at 12 into engagement with teeth 13a of a ratchet wheel 13 on the paper feed roller 14. In operation, the toothed rack lever 26 is rocked about pin 27 on energization of an electromagnet 7 against the clockwise bias of a return spring 28 into engagement with a rotatable gear 5 on the print drum 4 (Fig. 3, not shown) whereby the rack lever 26 is longitudinally downwardly moved on pins 16, 17 to ratchet the fingers 10 over a tooth 13a on ratchet wheel 13, the rack lever 26 striking a pin 18 at the lower end of its travel to disengage the rack teeth 26a from gear 5. A return spring 9 is then effective to upwardly move the plate 8 to its initial position, the ratchet finger 10 effectively moving upwardly with the plate 8 to rotatably index one toothed step of the ratchet wheel 13 and its associated paper feed roller 14. It is stated that the reaction when the rack lever 26 engages with the gear 5 is effective to produce a force (F) (Fig. 3) tending to bias the lever 26 counterclockwise to prevent unintentional disengagement of the rack lever 26 and gear 5 and just before the lever 26 strikes the pin 18 the force (F) is stated to then bias the lever 26 clockwise for readily disengaging the rack lever 26 from gear 5 when the lever 26 strikes pin 18. A damper (29) (Fig. 4, not shown) may replace a return stop 8a to damp the return movement of the rack 26 under the load of the return spring 28.

Abstract: A siloxane of the formula AcO(SiR2O)nAc, in which each R is a monovalent hydrocarbon or halogenated hydrocarbon radical, each Ac is a saturated aliphatic monoacyl radical of 1 to 3 C atoms and n is an integer greater than 9, may be made by reacting at above 50 DEG C. (1) an organosiloxane having attached to each Si atom 2 or 3 R radicals and (2) at least one mol. per mol. of (1) of acetic anhydride to produce a polymer having a degree of polymerization less than that of (1).  If desired the reaction may be effected in the presence of a catalyst, e.g. boron triacetate or pyridine, and a solvent, e.g. toluene xylene or methyl isobutyl ketone.  An alternative process is described in Specification 899,938.  Examples describe the preparation of acyloxy-terminated siloxanes from hydroxy-terminated siloxanes and (1, 2 and 6) methylvinyldiacetoxysilane or (7) phenylmethyldipropionoxysilane, and the preparation using acetic anhydride is described in Examples 3, 4 and 5.  Uses: The process is useful in salvaging silicone rubber stocks by breaking down a cured polymer or high molecular weight gum into usable liquid and gum components.

In order to reduce the tendency to separation of the carcass cords in the bead region of a pneumatic tyre including a radial cord carcass ply of non-metallic cords looped around the bead wires, each loop is internally and externally coated with an elastomer or elastomeric mixture having a modulus of elasticity M100 (in g/mm.<SP>2</SP>) at 100% elongation not exceeding four-fifths of the modulus of elasticity M (in kg./mm.<SP>2</SP>) of the carcass cords at one-tenth of their tensile breaking load. Since (it is stated) the Shore hardness S of the elastomer is equal to 56 log 10  M 100 -67, then the above requirement is equivalent to a requirement that S should not exceed 56 log 10  M-72À5. The external coating maybe surrounded by a ply of metal cords. The carcass cords may be of rayon, polyamide, polyester or polyvinyl resin. In an example nylon carcass cords have a modulus of 280 kg./mm.<SP>2</SP> and the coating material has a Shore hardness of 60 and a thickness of 2 mm.
