Abstract: 1,248,595. Chlorinating &c. ores in high intensity arcs. IONARC SMELTERS Ltd. (NPL). 11 Dec., 1968 [14 Dec., 1967], No. 58951/68. Heading C1A. [Also in Division H5] Powdered ore is heat-treated in a "high intensity arc", (with an elongated tailflame), with a controlled atmosphere (see Divisions H3-H5 for apparatus), inter alia, to put the metals in an easily recoverable form, e.g. as chlorides or by conversion of complex minerals to simple compounds. The material is supplied to the arc in a carrier gas which is inert, such as nitrogen or argon, or is a reactant gas such as oxygen, carbon monoxide, a halogen-containing gas, natural gas, air or hydrogen. A pre-heating step using a conventional plasma torch is mentioned. Specific metals mentioned in the ores include iron, aluminium, magnesium, nickel, cobalt, copper and traces of gold, silver, and platinum group metals. Using added NaCl, or a chlorine carrier gas, the precious metals may be extracted as chlorides from an ore. Specific examples refer to heat treating (1) the residue from pressure leaching a Ni-Co concentrate, the treatment enabling the Ni to be simply extracted by leaching or after chlorination using chlorine as the plasma arc gas or adding sodium chloride to the feed material; and (2) Au- and Pt-bearing Tulameen sand with 10% addition of NaCl or using chlorine carrier gas, the treatment significantly increasing the concentrations of Au and Pt obtained in chloride form.

Title: Method of sorting pieces of washing in laundries
IPC: B07C5/34
Filed: 1978-11-10
Abstract: An alpha-numeric and mechanically readable reference number (4) is marked on a patch attached to each item (2) of a batch of a customer's laundry; the number being specific to that customer. For processing, that number is associated with a transit number (e.g. from 1 to 100) and both are fed to a data processor (5) which stores them and the number of pieces of laundry associated therewith. The batch is then laundered and ironed at a station 6 and sent on to a despatch station 7 as individual and unsorted items.

Patent GB-2016587-A (GB)
Title: Hydraulic pressure converters
IPC: B60T13/14
Filed: 1979-03-01
Abstract: A hydraulic pressure converter, e.g. for powering a vehicle braking system, comprises a differential piston 3, 4 which works in a stepped bore 2 in a housing 1. A pressure space 9 is defined in the housing at the end of a portion 4 of the piston 3 which is of smaller area so that reciprocation of the piston 3 in the bore 2 causes hydraulic fluid to be drawn into the pressure space 9 through a first one-way valve 10 and then pumped to an outlet 13 through a second one-way valve 11. Reciprocation of the piston 3 is accomplished by subjecting the piston 3 to pressure from a pump to move the piston 3 in a first direction away from a stop face 54 and against the force in a compression spring 29 so that hydraulic fluid is drawn into the pressure space. A valve assembly 22 is operative to reduce the force urging the piston 3 in the first direction when the displacement attains a predetermined value whereafter the spring 29 is operative to urge the piston 3 in a second opposite direction to force fluid to the outlet 13 from the pressure space 9. <IMAGE>
Patent GB-2015526-A (GB)
Title: Naphthopyrans
IPC: C12P17/06
Filed: 1979-03-06
Abstract: Processes for the preparation of a naphthopyran derivative comprise reducing a compound (designated nanaomycin E) of the formula:-   <IMAGE> whereby the naphthopyran derivative (designated nanaomycin A) of the formula:   <IMAGE> is obtained. The reduction is conveniently effected under weakly acidic or alkaline conditions. When nanaomycin E is produced by fermentation of a micro-organism, for example, Streptomyces rosa variant notoensis, the conversion is preferably effected by adding a reducing agent to the fermented liquor containing nanaomycin E. Nanaomycin E is a new compound related to nanaomycin A and its antibiotic activity is, in general, equal to or weaker than that of nanaomycin A. The conversion is carried out more effectively by using the reducing agent, in association with a monosaccharide having a weaker reducing activity.
