Abstract: ABSTRACT OF THE DISCLOSURE           A method of treating pyrite bearing polymetallic material comprising heating the material in the atmosphere of reducing gases at a temperature of 450 to 500°C for a period of 30 to 60 min.           Gases such as hydrogen, or products of conversion of natural gas or mazut can be used to provide the reducing atmosphere.           The roasted copper-containing material is cooled at a rate of 2 to 4 deg. per min and is then subjected to magnetic separation.           The operation of magnetic separation is carried out in two stages with the intensity of magnetic field ranging from 1000 to 2000 oersted, whereafter copper sulphides are removed from the roast, with the magnetic field intensity ranging from 4500 to 6000 oersted.

Abstract: ABSTRACT   A venting device for use with a container closure cap of the type having a flexible pouring spout which is extendable to a pouring orientation from a nested orientation includes a hollow central body portion having a top end, a base and an interior passageway extending therethrough.  Joined to the top end of the central body portion is a generally cylindrical portion and joined to the top of this generally cylindrical portion is a frustoconical portion.  The base of the central body portion is integrally joined to a substantially flat flange portion which includes a spaced plurality of outwardly radiating ribs.  The venting device is joined to the flexible pouring spout of the container closure cap by means of spacer strips which are heat welded between the venting device and the closure cap thereby positioning the venting device in a concentric relationship to the closure cap.  These spacer strips provide a series of air flow passageways for the entry of venting air so that such air does not enter the pouring orifice which would result in pulsations to the exiting liquid flow.  The outwardly radiating ribs are pulled into abutting engagement with the edge of the flexible pouring spout when the spout is extended to a pouring orientation and these ribs provide only a very slight clearance for the venting air to enter the container so that the clearance provided is sufficiently small to prevent the exit of viscous fluids through the clearance areas.

Abstract: Motor Cooling System for Refrigeration Machine Abstract Motor cooling system for refrigeration machine wherein one condenser connected to a main stage of the compressor is used to satisfy the cooling requirements of the system and a second condenser connected to a subsequent higher pressure compressor stage is employed for heating a medium to satisfy heating requirements of the system.  The motor cooling system contains a three-way selector valve which connects either condenser selectively to the motor housing in response to the pressure in one condenser exceeding the pressure in the other condenser to provide a sufficient liquid refrigerant to the motor for cooling motor components under all operating conditions.  The selector valve comprises a horizontally extending tubular portion having an annular seat at each end of the portion and a vertically extending tubular portion attached thereon.  An axially movable ball is arranged in a horizontal portion to open selectively either seat and close selectively the opposite seat in response to the refrigerant pressure acting on the ball.

Abstract: The invention relates to a new class of high-hardness abrasive products and wear resistant parts based on alumina and aluminium oxycarbides. By fusing alumina in the presence of a carbonaceous substance and by controlled cooling, it is possible to obtain a large number of products in which the ratio  rho  of the number of carbon atoms to the number of carbon atoms plus oxygen atoms is between 0.01 and 0.50, and preferably between 0.02 and 0.20. These products are essentially constituted by primary alumina crystals in a eutectic matrix Al2O3 - Al4O4C or Al2O3 - Al2OC.

Abstract: A B S T R A C T     The invention relates to separators for separating relatively magnetic particles from relatively non-magnetic particles in the dry state.  The method of the invention involves allowing a mixture of the particles to flow past a magnet, preferably a high strength magnet, which is so arranged as to produce a strong magnetic field in a radial direction, the radial component greatly exceeding the axial component and the axial component exerting a force which is preferably substantially less than that of gravity.  In this way, the magnetic particles are diverted towards the magnet but not retained by it while the non-magnetic particles continue in their original path.

Abstract: VALVE TYPE VOLTAGE ARRESTER DEVICE       ABSTRACT OF THE DISCLOSURE   A low voltage valve type arrester device for conn-ection between a domestic electric supply line and earth includes a varistor, a switching device and an encapsulated gas discharge voltage arrester connected in series.  The switching device includes two switch members connected together by a solder connection and biased apart by a spring.  A fusible link is connected to the two switch members in parallel with the solder connection.  When a voltage surge occurs, current flows through the arrester to earth.  If the surge is large enough to render the gas discharge arrestor continuously conductive the solder connection melts due to the heat dissipated in the varistor and the two switch members move rapidly apart.  The fusible connection rapidly melts by which time the switch members are sufficiently far apart for no are to form between them.

Abstract: Abstract of the Disclosure A fluid mixing system and method is disclosed for automatically mixing precise concentrations of photo-graphic processing chemistry to be used in an X-ray film processor.  The system produces a fresh batch of mixed solution whenever a previous batch has been reduced to a predetermined minimum volume.  A pair of substantially identically constructed mixing units are provided to produce both developer and fixer solutions for film processing.  Each unit has:  a chemical supply structure for supplying chemicals from containerized supplied; a storage and mixing tank structure which underlies the chemical supply structure and defines a reservoir for mixing the chemistry with water; a water input valve for selectively introducing water under pressure into the tank structure; control apparatus for conditionally controlling operation of the water valve; and a chemical release assembly which is coupled to and actuated by the water valve.  The chemical release assembly is operated by the pressure of the water as the water is admitted through the water valve.  Operation of the release assembly causes piercing of the containers, allowing the chemistry to drain into the reservoir.  The pressurized water creates a swirl for agitating and thoroughly mixing the chemistry and the water.

Abstract: ABSTRACT OF THE DISCLOSURE:           A bit-by-bit time-division digital switching net-work switches incoming and outgoing isochronous digital channels having rates which are different but sub-multiples of a given low rate. After phasing incoming channels, bits having a predetermined binary state are detected. Previously stored addressed words of the outgoing channels to be switched to the incoming channels are read out and are multiplexed into an intermediate multiplex highway in response to incoming channel bits having the predetermined state. This predetermined state is that of the received bit, resp. its inverse if the sum of the incoming channel word bits is less than, resp. more than half the number of incoming word bits. Each multiplex highway multiframe is composed of a number of outgoing channel address words equal at the most to half the number of incoming channels. A frame or certain parts of the multiframe in the multiplex highway indicate by the presence or the absence of the outgoing channel address word, whether or not the incoming channel word bits have been inverted.
