Abstract: ABSTRACT OF THE DISCLOSURE      In the processing of sulphidic copper ores containing as impurities other valuable metals, it is desirable to first try to separate the copper from the other metals.  The copper may then be more easily purified and the remaining metals may be recovered.  There is no hydro- or pyro-metallurgical process for so treating these ores.  The present  in-vention seeks to overcome this drawback by providing a process for the production of blister copper from copper ores or concentrates which contain harmful or economically significant amounts of other nonferrous metals com-prising using flash smelting, known per se, for the primary smelting of the concentrate to produce a matte or metal or both containing 70-98% Cu and a slag containing less than 1% S from the concentrate; recycling flying dust to the feed, reducing the produced slag containing less than 1% S in an electric furnace by means of coke at a temperature of 1300-1550°C to a copper concentration of less than 0.5% and mainly into a copper-lead-iron alloy; converting mattes, raw metals or raw metal alloys or a mixture thereof produced in the flash smelting furnace and the electric furnace into blister copper; feeding slag produced therein and containing less than 1% S together with the slag from the flash smelting furnace into the electric slag purification furnace; purifying the blister copper obtained from the converter into anode copper in an anode furnace; and feeding the produced flying dust, which has a high nonferrous metal content including zinc and lead, but  a low content of copper, as a raw material into the process for producing the metal.

Abstract: APPARATUS AND METHOD FOR MAKING  DISPOSABLE PACKET ASSEMBLIES            Abstract of the Disclosure An apparatus and a method for producing packet assemblies consisting of a plurality of interconnected dis-posable dispensing packets, each containing an individual material to be dispensed.  In accordance with the apparatus and method aspects of the invention, a continuous strip is formed incorporating a plurality of longitudinally spaced pockets which are open along one lateral edge of the strip. The strip is advanced sequentially into engagement with a series of rotary filling devices, each formed with filling stations around the periphery thereof and are adapted to fill selected ones of the pockets with a selected material in an ordered repetitive sequence.  After each filling oper-ation, or at the completion of the filling operations, the open lateral edge of the strip is sealed, forming a series of packets. The filled and sealed strip is thereafter severed into sections, each comprising a prescribed number of interconnected disposable dispensing packets.

Abstract: GRASS COLLECTING MULTIPLE BLADE MOWER      WITHOUT AUXILIARY BLOWER MEANS     ABSTRACT Of THE DISCLOSURE     The four-wheel lawn and garden tractor has an underslung  two blade mower unit and a rear mounted grass catcher.  The multiple spindle mower unit incorporates special baffling to improve lateral movement of cut grass from the mower housing.  The conduit between the mower housing discharge opening and the rear mounted grass catcher includes a unique elbow part having a configuration which facilitates efficient movement of the grass from the mower to the catcher.  The grass catcher is vented so that there is very little back pressure in the interior of the grass catcher.  Venting is accomplished by provision of a downwardly facing opening along the rear of the grass catcher cover, the latter being molded of an impervious plastic material.  The grass catcher cover has a downwardly extending skirt at the front thereof with a pair of laterally spaced semicircular notches adapted to receive a discharge conduit.  Thus the cover may be used on tractor mowers discharging to either their left or right side.

First-stage cylinders accept a constant double charge of air, sufficient for burning the maximum allowed amounts of fuel in both first and second stages.  Combustion chambers are separated from cylinders with connecting valves, first-stage chambers have measuring cells with spark ignition, second-stage chambers use auto-ignition.           Fuel supplied directly to chambers using dual injectors giving separate control to each stage.  Excess cylinder gases lower temperatures after combustion and retain heat.  External cooling is reduced.  Enlarged second-stage cylinder allows extended expansion of gases.           Check valve in second-stage exhaust duct allows recovery of negative work input at light loads.  Basic engine unit consists of two first-stage cylinders operating on a four-stroke cycle and one second-stage cylinder using a two stroke cycle.  working alternately with the two first-stage cylinders.  Methods of combining two or more basic engine units are also disclosed.

Abstract: A modular farm tractor whose wheels are driven by individual A.C. induction motors and whose accessories or attachments are also driven by A.C. induction motors. A prime mover, such as a gas turbine operating at a constant speed, is mounted on the tractor and drives a three-phase alternator which produces A.C. power at a constant frequency of 400 Hz.  The frequency of the power applied to the wheel motors is controlled by a first cycloconverter means connected to the output of the alternator.  The alternator output is also coupled through a second cycloconverter means to an A.C. power outlet mounted on the tractor.  Various farm accessories associated with the tractor are driven by A.C. induction motors connected to the A.C. outlet.  The frequency of the power applied to the accessory motors is controlled by the second cycloconverter means.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of manufacturing a padding cloth for belts, the cloth having a latent curvability property such that it can be deformed by differential shrinkage caused by heat treatment so that one of its side edges becomes concave and its opposite side edge becomes convex.  A liquid fabric sizing composition is applied to a continuous belt-like cloth having thermal shrinkage rates which vary stepwise across the width of the cloth so as to increase toward a side edge of the cloth to impart the latent curvability property thereto.  The cloth is then dried and moved into and through a heating device.  The dried, sized cloth is moved into the heating device at a faster rate than the rate at which it is withdrawn from the heating device so that the cloth is in a relaxed state during its passage through the heating device   The portion of the cloth having the lowest thermal shrinkage rate is thereby shrunk to the maximum extent in the heating device so that this portion is thermally stabilized and is not capable of further shrinkage, while the other portions of the cloth having higher thermal shrinkage rates remain not com-pletely thermally stabilized and capable of further shrinkage.          Adhesive powder is then applied to an entire surface of the heat-treated, dried, sized cloth, and the adhesive powder is melted and pressed into the cloth to bond it to the cloth.  The cloth is then cooled to solidify the adhesive, and wound up on a roll in a straight state.

Abstract: ABSTRACT OF THE DISCLOSURE A roofing element is disclosed of the type essentially consisting of adhesive foam plastic whose upwardly facing surface is provided with a covering plate.  It has been difficult with the heretofore known roofing elements of this type to obtain an adequate stability to changing moisture and temperatures and the consequent variations in pressure under the roofing felt.  The invention provides a roofing element obviating these drawbacks and being mechanically solid, and this is achieved according to the invention by making the roofing element so that the covering plate is composed of a bituminous roofing felt, whose surface facing the element is covered with gravel or pebbles, and providing a layer of glass fibre contacting said surface of the roofing felt and provided with through holes through which the adhesive foam plastic during foaming is caused to adhere to the bituminous roofing felt.
