Abstract: ABSTRACT OF THE INVENTION         A signal mixing circuit for blending two signals, such as left and right channel FM stereo signals, blends the two signals at each of two outputs in response to a variable control voltage, which acts upon a transistor network connected between the two signal paths.  When the variable control voltage is determined by an amplitude detector connected in a conventional FM stereo receiver, the output signals will be blended to a greater degree when the received signal strength of the broadcast FM signal becomes weaker.  In a further embodiment, capacitors are added to inhibit high-frequency components of one channel and to add in high-frequency components of another channel thereby eliminating and canceling the noise components normally present in the respective signals and improving the S/N ratio.

More  particularly,  an improved thin-film, large area solar cell, and meth-ods  and  apparatus for  forming  the  same,  having a relatively high light-to-electrical energy conversion efficiency and characterized in that the cell compri-ses a p-n-type heterojunction formed of:  i) a first semiconductor layer comprising a photovoltaic active material selected from the class of I-III-VI2 chalco-pyrite ternary materials which is vacuum deposited in a thin "composition-graded" layer ranging from on the order  of  about  2.5  microns  to  about  5.0  microns (?-2.5µm to ?-5.0µm) and wherein the lower region of the photovoltaic active material preferably comprises a  low  resistivity  region  of  p-type  semiconductor material having a superimposed region of relatively high  resistivity,  transient  n-type  semiconductor material defining a transient p-n homojunction; and ii),  a  second semiconductor layer comprising a low resistivity  n-type  semiconductor  material;  wherein interdiffusion a) between the elemental constituents of the two discrete juxtaposed regions of the first semiconductor  layer defining a  transient  p-n homo-junction layer  and b) between the transient n-type material  in  the  first  semiconductor layer and the second n-type semiconductor layer, causes the tran-sient  n-type  material  in  the  first  semiconductor layer to evolve into p-type material  thereby defin-ing a thin layer heterojunction device characterized by the absence of voids, vacancies and nodules which tend  to reduce the energy conversion efficiency of the system. In the illustrative form of the invention described, the first semiconductor layer is prefer-ably  formed  of  a  first  region  of  low resistivity p-type chalcopyrite material  such, for example, as copper-enriched CuInSe2 to which is applied a tran-sient high resistivity n-type region of copper-defi-cient CuInSe2, while the second semiconductor layer preferably  comprises  an  indium-doped  CdS  n-type layer.

Abstract: Abstract of the Disclosure A multicolour inked ribbon cartridge for an impact serial printer has a body housing a ribbon, and two spaced arms protruding from the body and supporting a portion of the ribbon for interposition between a printing head and a printing medium along the whole length of a platen.  The cartridge body is supported for pivotal movement in the printer frame about an axis parallel to the platen, so that different colour bands on the ribbon can be moved between the printing head and the printing medium by pivotal movement of the cartridge.  Such movement may be achieved by a motor driven cam acting on the cartridge body.          A cord stretched between the arms of the cartridge acts as a guide for a ribbon positioning and guiding element, the latter being coupled to the cord so that it may move freely transversely of the cord but moves with the cord to reflect tilting of the cartridge, and being coupled to the printing head so that it moves transversely with the latter, but can move freely in a perpendicular direction.

Abstract: PURIFICATION OF ETHYLENE GLYCOL DERIVED FROM                ETHYLENE CARBONATE                          INVENTOR MITCHELL BECKER HOWARD M. SACHS     ABSTRACT          Ethylene glycol is purified, particularly for fiber-grade applications, by removal of the residual ethylene carbonate from which the glycol was derived. The effluent from a reactor in which ethylene carbonate is hydrolyzed to ethylene glycol is distilled to produce a lower-boiling fraction comprising ethylene glycol and water and a higher-boiling fraction comprising ethylene glycol, higher glycols, and concentrated in hydrolysis catalyst.  The higher-boiling fraction is recirculated to reflux against the lower-boiling product, thereby reducing the ethylene carbonate content of the ethylene glycol to very low levels suitable for fiber-grade applications.
