Abstract: ABSTRACT OF THE DISCLOSURE        A stereo speaker system is disclosed having at least three individual speakers arranged along a path, with one of the speakers positioned between the other two speakers and connected to receive signals from one channel of a stereo signal source such as a stereo radio.  Both of the other two speakers are connected to receive signals from the other channel of the stereo signal source.  Balanced stereo images are thus obtained simultaneously at two different locations.  The system has particular application in an automobile.  Other embodiments are disclosed using more than three speakers.

Abstract: ABSTRACT OF THE INVENTION:            According to the subject invention, the correction for thermal mistracking may be achieved by the incorporation of a compensating plate in the carriage,  the plates' length and coefficient of expansion being selected to nullify the off-track shift with temperature.            Mistracking which varies from the outside to the inside track, i.e., there is a change in stroke length of the carriage with temperature, is compensated for by select-ing a pulley material from a material having a coeffi-cient of expansion directly related to the coefficient of expansion of the material of the disc.  The result of a proper  selection  is  that the  change  in  size with ambient temperature of the disc is correlated with the change in size of the, band with the same temperature, so that  the total  effect  is  as  close  to  a  nullity  as possible.

Abstract: TITLE           A Method and Device to Prevent Beavers from Blocking Drainage Channels ABSTRACT In a situation where animals, such as beavers, attempt to flood lands by blocking culverts or constructing dams across waterways, a device is used to maintain a constant flow of water through the dam or culvert.  An elongated pipe or culvert with a downwardly directed opening distant from the culvert or dam is used.  On the end of the pipe closest to the culvert is a gate which prevents animals and debris from passing through but allows for the smaller elongated pipe to communicate with the culvert. the beaver instinctively attempts to dam the gate area rather than dam the underwater opening of the elongated pipe, and thus is unsuccessful in stopping the flow of water.

Abstract: ABSTRACT      A rim driven rotary saw and a circular saw blade useful in cutting operations is disclosed.  The saw blade is rotated by a drive pinion or sprocket which is engage able with cutting projections extending about the perimeter of the saw blade.          Because the saw blade is rim driven, it does not require a central arbor and thus has particular application to automated tree cutting and felling.  By using a drive pinion having con-ventional gear teeth thereabout and which mesh with cutting projections about the circular body of the saw blade, a positive drive is achieved.  Each projection has the profile of a conventional gear tooth which is modified so that in the direction of saw blade rotation, the leading face portion is cut out from a point proximate the juncture of leading face and leading flank to a cutter located at the intersection of the cut out section and the top land.  The leading face cut out effectively results in a setback of the cutter whereby contact by the cutter with the teeth on the pinion are avoided.          But for the cut out, a positive and back-lash free engagement between the gear teeth of the pinion and the cutting pro-jections which function as gear teeth on the saw blade is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and an ocean-going vessel are disclosed for more effectively incinerating hazardous liquid wastes at sea.          Intermodal shipping tank containers are filled at waste generation sites; transported to dockside and loaded above decks on an incin-erator ship; taken out to sea and incinerated in horizontal, liquid burning type incinerators so that the effluents emerge horizontally.  Wastes flow by gravity from containers into staging sumps located below decks, and then pumped to incinerator.  Pollu-tion abatement tanks, also below decks, collect spilled waste from containers, as well as overflow from staging sumps.  Material collected in abatement tanks is pumped into staging sump, and pumped to incinerator.  Fuel oil may be introduced into sumps for fueling incinerators to maintain incinerator operation when there is insufficient supply of waste.  Effluents are sea-water scrubbed for cooling to eliminate thermal lift and carried promptly into sea.

Abstract: ABSTRACT      Filled rubber vulcanizates containing aromatic furazan oxides exhibit many improved properties such as increased filler-rubber interaction and decreased hysteresis. Useful furazan oxides have both carbons of the furazan ring as part of a fused aromatic ring. Typical examples are benzofurazan oxide and its methyl and methoxy analogs. Tires made from the inventive vulcanizates show lower running termperatures and improved rolling resistance. The desirable effects of aromatic furazan oxides may be improved by mixing the rubber, filler and furazan oxide in a conventional mechanical compounding device at specific temperatures and time periods such as about 200-400°F for 2-20 minutes.

Abstract: ABSTRACT OF THE DISCLOSURE    Soluble hexavalent chromium values are removed from aqueous  chlorate  solutions  by  employing  a  critical effective ratio of OH- : Cr2O7= ions of at least 3:1 in the  aqueous  chlorate  solution  and  by  employing  a dithionite  to  reduce  the  hexavalent chromium  to trivalent  chromium,  preferably  in  the mole  ratio  of S2O4= : Cr2O7= of at least 3:1.  The trivalent chromium forms chromic hydroxide (Cr(OH)3) with the hydroxyl ions and precipitates  from the  aqueous  chlorate solution.          The  process  is  rapid  and  effective  in  quantitative removal of hexavalent chromium from the aqueous chlorate solutions and is especially useful for the removal of sodium dichromate from cell liquor which is intended to be employed in chlorine dioxide production and which is produced  by  diaphragmless  electrolysis  of   sodium chloride.
