Abstract: ABSTRACT OF THE DISCLOSURE        Gold, as well as copper, is recovered from copper bearing sulphidic material containing gold. The copper bear-ing sulphidic material is subjected to a main leach to provide a copper containing main leach liquor and a main residue. A secondary leach with ammonium thiosulphate solution is carried out on the copper bearing sulphidic material before the main leach, or on the residue from the main leach, to provide a gold containing secondary leach liquor and a secondary residue.      Copper and gold are recovered from the respective leach liquors.      Silver may also be recovered in addition to the gold.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for making an aromatic carboxylic acid of high purity by feeding an essentially equilibrium hydrolysis mixture of an aromatic nitrile to a reactive distillation column operated at a temperature of from about 200°C. to about 325°C. at autogenous pressure where the equilibrium mixture is subjected simultaneously to further hydrolysis and distillation of ammonia, removing water vapor and ammonia from the top of the column, subjecting remaining equilibrium hydrolysis mixture to further hydrolysis and distill-ation in a reboiler, returning vapor from the reboiler to the distillation column, removing an aqueous solution of product acid from the reboiler, cooling said separated solution, and separating acid product.  In one embodiment of the invention the hydrolysis mixture is obtained by subjecting a nitrile from the ammoxidation of an alkyl aromatic compound to aqueous hydrolysis in a closed reactor at about 200°C to about 325°C. until an essentially complete equilibrium is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE         An isotope separation arrangement for separating a preselected isotope from a mixture of chemically identical but isotopically different molecules by either photon-induced pure rovibrational or vibronic selective excitation of the molecules containing the atoms of the isotope to be separat-ed from a lower to a higher energy level, and a chemical reaction of the high-er energy level molecules with a chemically reactive agent to form a chemical compound containing primarily the atoms of isotope to be separated in a physi-cochemical state different from the physicochemical state of the mixture of chemically identical but isotopically different molecules.  The chemical compound containing the atoms of the isotope to be separated may be subsequent-ly processed to obtain the isotope.

Abstract: WALL FORMING STRUCTURE FOR POURED           CONCRETE WALLS.     Abstract of the Disclosure:           A wall forming structure is disclosed, where very large panels may be formed having sheathing placed against a plurality of studs which are, in turn, secured to at least a pair of strongbacks where the strongbacks comprise a pair of channel-shaped members in spaced back-to-back relationship.          The panels are placed in opposed relationship to form a cavity into which concrete is placed to form a wall, and the panels may each be moved as a single unit  --  depending upon their overall size.  Indeed, using suitable spacers, the entire wall form may be constructed away from the place where a wall is to be formed, and be lifted or moved into place using suitable handling equipment such as cranes.  Each strongback comprises a pair of channel-shaped members where there is an outwardly facing T-shaped slot formed in each side wall of each channel, and a plurality of plates each having an opening through its thickness is secured to each pair of channel-shaped members at each place where a tie will extend between the panels.  Generally, the channel-shaped members of the strongback and the studs which are secured to the strongbacks and to which the sheathing is secured, are extruded aluminum.

Abstract: IMPROVED LEG AND GUIDE CONSTRUCTION       FOR USE IN JACKUP BARGES            Abstract of the Disclosure An improved leg construction is disclosed for jackup barges.  The barge leg is typically of triangular construction.  The members of a leg including the three verticals extending along the leg are preferably constructed of tubular members.  The vertical tubular members include on the inside a rack formed of teeth to engage an elevating gear drive unit.  Adjacent to the teeth, an undercut on both sides of the slot in the exterior of the tubular member is formed, locking the guide mechanism to the tubular member.          This construction measurably improves the profile of the jackup leg to impinging wave action from any direction, thereby reducing the resistance of the leg to water and permitting a reduction in the leg weight and hull size.

Abstract: ABSTRACT :                     A cassette player or recorder has a plastic housing and a magnetic head unit which moves relative thereto and which consists of a head support with magnetic heads and a pressure roller mounted thereon. During recording or playback a cassette bears on supporting means, whose position is defined by the position of the magnetic head unit, so that the position of the cassette relative to the magnetic heads and the pressure roller during playback and recording is determined or at least partly determined, by the position of the magne-tic unit. Possible variations in respect of the correct position of the magnetic head relative to the magnetic tape in the cassette owing to manufacturing and dimensional tolerances of the various components are minimized when the cassette bears on a cassette support which is rigidly connected to the head support and is situated near the magnetic head.

Abstract: Abstract of the Disclosure This invention provides a leak proof seal between a high pressure fluid line and a gauge monitoring the pressure Or the fluid in the line.  This seal transmits pressure fluctuations between the measured fluid and a dissimilar fluid in the standing line connected to the measuring gauge and prevents the coningling of the two fluids.  This invention is particularly applicable in instances where the ambient temperature is below the freezing point of the measured fluid and a non-freezing fluid is required in the standing line and gauge.  The gauge protector seal comprises an in-line elastomeric piston and cylinder which passes through variations in the pressure in the measured line to the fluid in the standing line to the gauge while maintaining separation Or the two fluids and at the same time allowing the non-freezing fluid in the standing line to lubricate the piston.

The Main System Interface is designated as an IOT, or Input-Output Translator, and translates input-output instructions into proper form for delivery to a particular intelligent interface unit which can execute the instructions.  The IOT provides a data link identifier to identify each particular data-transfer transaction and receives result information from the Line Control Processor and Base Module to keep the Main System informed of the status or completion of each individual data-transfer operation.          The Input-Output Translator provides a selection of priority to be given to competing Line Control Processor requests for access to Main Memory and communicates with individual Line Control Processors in their control of data-transfer operations between various peripheral devices and the Main Memory of the System.

Abstract: ABSTRACT    The invention is directed to a power operated jig-saw which includes a housing and an elongated saw-blade holder for holding a saw-blade.  A first bearing pivotally mounts the elongated saw-blade holder in the housing.  A drive imparts a reciprocating up and down movement to the elon-gated saw-blade holder.  A cam arrangement imparts a reciprocating movement to the elongated saw-blade holder and includes a body rotatably mounted in the housing and operatively connected to the drive.  The rotating body has formed thereon a continuous cam surface extending about the axis of rotation thereof.  The cam arrangement also includes a carrier and a resilient member.  The carrier is mounted in the housing so as to be reciprocally movable in a direction transverse to the elongated saw-blade holder and carries a bearing for slideably holding the saw-blade holder.  The resilient member urges the carrier into engagement with the cam surface whereby the carrier is reciprocated in response to the rotational movement of the cam surface causing a saw-blade attached to the saw-blade holder to trace out an enclosed path.
