IPC: C22B/
Filed: 1973-10-22
Abstract: 1454086 Recovering zinc from ferrites ASTURIANA DE ZINC SA 17 Oct 1973 [20 Oct 1972] 48470/73 Heading C1A A method of recovering zinc from material containing zinc ferrites comprises treating the material in a first stage, constituting a combined ferrite dissolution and iron removal stage, with a solution of sulphuric acid to dissolve the zinc ferrites, the zinc of the dissolved ferrites being taken into solution in the form of zinc sulphate, and to precipitate most of the iron of the dissolved ferrites in the form of a jarosite compound, the solids subsequently being separated from the solution and the zinc being recovered from the solution after purification of the latter. It is preferred in the first stage to add Na<SP>+</SP>, K<SP>+</SP> or NH 4 <SP>+</SP> ions to facilitate precipitation of dissolved iron in the form of a jarosite compound and also to neutralize with, e.g. ZnO until the acidity of the solution is 10-100g./l. of H 2 SO 4 . The resulting solution may be neutralized in a second step with further ZnO until its acidity is 2-10g./l. of H 2 SO 4  to remove the remaining iron as a precipitate. A temperature of 50‹ C. to bp is preferably maintained throughout the process. Any Fe<SP>++</SP> ions present or formed may be suitably oxidized by MnO 2 . Reference has been directed by the Comptroller to Specification 1322745.

Title: Method of nitrocarburizingof metal rings
Inventor: TOMMIS NORMAN
IPC: C23C8/32
Filed: 1982-12-16
Abstract: A metal ring of generally rectangular cross-section has its radially outer surface and its side surfaces treated by being stacked with its sides in contact with other rings in a chamber. Air is excluded from the chamber and a gaseous mixture of a carburizing gas and a nitrogenous gas at a temperature of 450 DEG  C. to 650 DEG  C. is supplied to the chamber. The proportions (% by volume) of the gases is between 25:75 and 75:25. The mixture nitro-carburizes both the radially outer surface of the stacked rings and the sides of the ring. If the rings are finish machined before treatment, they are ready for use as soon as they are removed from the chamber. The nitro-carburizing treatment reduces wear on the treated surfaces. The rings are used as piston rings or sealing rings.

IPC: A61M25/01
Filed: 1991-01-11
Abstract: The guide catheter system (10) for use in the treatment of coronary artery disease includes a first single-lumen catheter (12) of a relatively large internal diameter to pass a second guide catheter (26) therethrough. The first guide catheter (12) comprises an elongated flexible tube having a stainless steel braid (14) embedded in the wall thereof for imparting desired torqueability characteristics to it. The first guide catheter (12) is intended to be inserted at an appropriate point in the vascular system and then advanced until its distal end reaches the coronary ostium. The second guide catheter (26) is fabricated by extruding a plastic, such as polyurethane thermoplastic resin over a tubular Teflon TM core (28) and because it is to be used within the lumen (24) of the first catheter (12), it need not include a braided structure within its walls to prevent it from kinking. This allows the second catheter (26) to be sufficiently slim to permit it to be advanced into a coronary artery while allowing fluids to be perfused between the outer wall of the second guide (26) and the inner wall of the first guide catheter (12) while still providing a sufficiently large inner lumen to pass a working catheter, e.g., an angioplasty or atherectomy catheter. An atraumatic tip (30) is attached to the distal end of the second guide catheter (26). <IMAGE>
