Abstract: Abstract The present invention relates to an apparatus for separating a material having mixed floating and sinking fractions.  A unit provides a fluid stream.  A first enclosed drum has an interior chamber which receives the fluid stream.  One end of the drum has an overflow opening.  A second drum is carried within the interior chamber of the first drum.  The second drum is partially within the fluid in the first drum and has an open end and an enclosed end, with the enclosed end having a central opening.  An enclosed screen container is carried within the interior chamber of the first drum adjacent the central opening.  A unit is provided for introducing the material to be separated together with the fluid stream into the screen container.  Materials retained by the screen container overflow into the second drum and fluid and materials passing through the screen container fall into the first drum to establish a fluid current within the first drum between the screen container and the overflow opening.  A portion of the floating fraction overflow into the second drum is separated in the fluid from the sinking fractions.  A unit is provided for agitatively moving the sinking fraction within the second drum toward the open end of the second drum, whereby the sinking fraction within the second drum is further separated from the floating fraction and the sinking fraction is introduced into the first drum.  A unit is provided for agitatively moving the sinking fraction introduced in the first drum in an opposite direction to the fluid current whereby the fluid current scrubs the sinking fraction to further separate the floating fraction therefrom and overflows the floating fraction through the overflow opening of the first drum.  A unit removes the sinking fraction from the first drum.

Abstract: METHOD AND APPARATUS FOR SPEECH RECOGNITION               AND REPRODUCTION            Abstract of the Disclosure A system capable of learning and subsequently recognizing a vocabulary of spoken words and synthetically reproducing such words as an audible voice when activated by an electronic command signal.  Voice signals in the form of a time sequence of binary digits are processed by a digital spectrum analyzer in a "training" mode for the system to provide digital information to form a voice print which is stored in a memory.  The digital spectrum analyzer comprises an arithmetic logic unit (ALU) that processes incoming data using only digital logic, without filter banks and in combination with a sequence or timing con-troller, an in/out controller and various internal memory components provided on a separate board or by an integrated circuit which may be combined with other external memory and external control circuitry to comprise the complete system.  With voiceprints provided either from system training or from external storage and with the system in the recognition mode, pattern matching of spoken words is accomplished using the spectrum analyzer.  The arithmetic logic unit, using basic logic functions, is programmed to provide a unique statistical analysis of the digital voice data so that accurate and rapid pattern matching, and hence word recognition, is accomplished even in the pre-sence of relatively high background noise.  Voice synthesis of words may be accomplished using the same methods and apparatus as used for recognition by essentially reversing the operation of the spectrum analyzer to synthesize voice signals from previously stored voiceprints.

Abstract: Abstract of the Disclosure An improved power steering apparatus includes a variable displacement pump  During a steering operation, a flow control valve effects operation of a motor. assembly to vary the displacement of the pump as a function of variations in the demand for power steering fluid.  Upon initiation of a steering operation, the displacement of the pump must be quickly increased to enable it to satisfy the impending demand for power steering fluid.  Therefore upon initial rotation of a steering wheel, a steering controller restricts a flow of fluid to operate the motor assembly independently of the flow control valve.  The displacement of the pump can thus increased before the flow control valve can be actuated during an initial portion of a steering operation.

Abstract: SHEET CARRIER FOR TRACTOR-FEED PRINTERS            ABSTRACT OF THE DISCLOSURE            Prior art methods of  transporting sheets of paper  such as letterhead sheets through tractor-feed printers have included the use of  glue, and  of vacuum,  to  hold the sheet onto  a carrier.  (The  carrier  has a  series  of holes  along  each  of  its edges characteristic of  the tractor-feed system.)  Pockets formed by  folding  the carrier  have  also  been  proposed.   Disclosed is  an improved  carrier where the  pockets  are formed  simply and  inexpensively by  the double thickness  band caused by  the  overlapping of pieces  of  the carrier.   This manner of  forming  the  pockets  lends  itself  to  the provision of an endless-loop type of carrier,  since the final  joint  between  pieces  can  be  made  after  the carrier has  been fed through the tractor rollers  of a tractor-feed  printer.  The pieces of the carrier may be plastic or paper  and  may be disposable  after  use  or re-usable depending on the type of adhesive used.

Abstract: "HYDROCARBON TREATING PROCESS HAVING        MINIMUM GASEOUS EFFLUENT"                                 ABSTRACT           A process is disclosed for treating hydrocarbon streams for the purpose of removing mercaptans and also converting the remaining mercaptans to disulfides which remain in the hydrocarbon stream being treated.  The hydrocarbons rise through a contacting column counter-currently to a descending stream of an aqueous alkaline solution.  A limited amount of an oxygen-containing gas is passed into an interme-diate point in the column thereby dividing it into an upper sweeten-ing section and a lower extraction section.  The flow rate of the oxygen-containing stream is preferably low enough that any gas not consumed in the catalytic oxidation of mercaptans becomes dissolved in the hydrocarbon product stream, and preferably remains dissolved at atmospheric pressure.
