Abstract: Abstract of the Disclosure Described is a procedure for virtually eliminating dislocations in multilayer structures of materials having a crystallographic zinc-blende structure, in particular quaternary layers of AlyGal-yASl-zPz grown on AlxGal-xAS substrates (Y > x ?O).  By carefully controlling the quaternary layer thickness and the lattice parameter mismatch at the growth temperature, it is possible to change the direction of substrate dislocations as they enter the substrate/layer interface.  The length of the dislocation in the interracial plane can be extended so that it is "infinitely" long, i.e., it reaches the edge of the water. As a result, the epitaxial quaternary layer and all layers subsequently grown thereon will be virtually dislocation free, provided that the thickness, stress and uniformity of the layers are such that no surface dislocation sources are activated.  Also described are double heterostructure junction lasers with reduced values of both stress and dislocations.

Abstract: ABSTRACT OF THE DISCLOSURE           A centrifugal drying mill for wet particles comprising an inlet chamber, an upstack leading from one end of the inlet chamber, a classification section connected to the upstack and a downstack leading from the classification section to the opposite end of the inlet chamber to form a generally arcuate centrifugal path, and an exhaust port between the classification section and downstack. The inlet chamber which has tangential nozzles leading into it from a source of hot gaseous fluid is enlarged relative to the remainder of the mill to effect a deceleration and circulation of the incoming particles in the inlet chamber simultaneously with movement of the circulating mass through the inlet chamber toward the upstack.  This in-vention provides a highly effective centrifugal drying mill for most materials, yet it is of reduced size to make it economically feasible for the treatment of small batches or for laboratory or testing purposes.

Abstract: SOLAR ENERGY HEATING SYSTEM     Abstract of the Disclosure A focused solar heating system is provided having a focusing reflector which is generally scoop-shaped. A solar collector plate is mounted on the front of the focusing reflector to directly accept direct solar radiation and diffuse radiation which strikes the front surface of the plate. The remainder of the entrance aperture of the focusing reflector accepts both on- and off-axis solar direct and diffuse radiation which is reflected by the focusing reflector and applied to the rear sure-face of the solar collector plate. The focusing reflector has a concave reflective surface made up of first and second merging curves which are optimized so that the front and rear surfaces of the solar collector plate accept the largest solid angle of both direst and diffuse rays from the sun and provides an optical gain which increases the efficiency of the system. The solar collection system may be incorporated in a vertical wall of a building and made partially transmissive, or may be incorporated in a separate structure for supplementing the heating or cooling of a building or providing hot water therefor,

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure relates to a process for the thermal re-fining of contaminated copper in the molten phase wherein, first runs of molten raw copper are bessemerized from copper matte into blister copper or from black copper into converter copper to form an intermediate product, and, subsequently, thermally refining said intermediate product to anode quality, characterized by melt-ing the intermediate product and simultaneously treating the molten substance with reaction media in two reaction levels located one above the other in a treating room.  It also relates to an apparatus for the thermal refining of contaminated copper in the molten phase which comprises a reactor and at least two separate means located one above the other for blowing-in reaction gas at different rea-cation levels in said molten phase.  This will make it possible to produce a copper of high degree of purity from contaminated black copper or copper matte.

Abstract: LINE CIRCUIT FOR KEY TELEPHONE SYSTEMS            ABSTRACT OF THE DISCLOSURE:         A line circuit for a key telephone system using as the main operative components, two relays i.e. a ring relay and a combined off-hook and hold relay and an optical coupler and rectifier bridge combination.  On a ring signal from the exchange, the optical coupler is activated to cause the energization of the ring relay.  On a station of the line going off-hook, the conventional A lead ground operates the off-hook relay and causes de-energization of the ring relay.  When a station of the line goes into hold, the circuit must differentiate this condition from a hang-up condition.  This differentiation is performed by the coupler sensing the line voltage as low or high.  The line voltage is high if the line loop is open indicating a hang-up condition.          The line voltage is low if the line loop is still closed during the sensing period as a preliminary to the hold condition.  The off-hook relay is held during this sensing operation so that the circuit may enter the hold condition when indicated.
