Abstract: ABSTRACT           A goal shield, particularly for the game of hockey, is described which has a variable target area through which a goal is scored.  A frame defining a goal opening and a plurality of readily attachable and detachable panels cooperate to form the goal shield.  A plurality of fasteners are provided on the frame and adjacent sides of the panels for interlocking the panels and the frame.  Selected panels are removed by disen-gaging certain fasteners to form random target areas in differ-ent locations in the goal opening.  Plates are rotatably mounted to the panels about through holes formed in the panels, additional target areas being provided when the plates are rotated to expose the through holes.

Abstract: REMOVAL OF BOD AND NITROGENOUS   POLLUTANTS FROM WASTEWATERS                  Abstract of the Disclosure A multistage treatment is disclosed for the removal of carbonaceous BOD and nitrogenous pollutants from wastewaters, wherein the influent wastewater undergoes successive nitri-fication-denitrification in the presence of recycled activated sludge containing a mixed culture biomass comprising hetero-trophic and autotrophic organisms.  The initial mixing of the wastewater with recycled sludge is effected in the presence of sufficient oxygen to maintain oxic conditions.  The mixed liquor from the initial oxic treatment, without intermediate separation of solids, is passed to an anoxic stage wherein nitrites and nitrates (NOx , x = 2,3) formed by oxidation of ammonium com-pounds are reduced to nitrogen gas.  Any number of oxic treating stages each followed by an anoxic stage may be employed.  The final treating stage prior to solids separation from the mixed liquor may be either oxic or anoxic.  The separated solids constitute the activated sludge recycled to at least the initial mixing stage.  A short residence time, resulting in a high food to biomass ratio, is maintained in the initial oxic stage or the first subsection thereof, in order to avoid sludge bulking and to promote an active dense biomass.

Abstract: Abstract of the Disclosure The present invention is directed to a process for removing and optionally recovering hexavalent chromium from chromium waste water.  The invention involves the use of a treatment mixture comprising the combination of barium carbonate and/or barium hydrate, plus one or more certain specified acetates.  The process involves contacting the chrome waste water to be treated with the treatment mixture at an acetic pH not e    .g 6.0, and usually from 4.0 to 6.0, followed by filtration through an acid-resistant filter. The chromium removed by this filter in the form of barium chromate can be regenerated into chromic acid by backwashing the filter into an agitated tank and treating to produce chromic acid and barium sulfate.  The thus-generated chromic acid can then be returned to the chrome plating tank for re-use after passing through a filter to remove the barium sulfate.

Abstract: ELECTROACOUSTIC TRANSDUCER WITH SPRINGS FORMING ELECTRICAL INTERCONNECTIONS AS A RESULT OF ASSEMBLY          Abstract of the Disclosure An electroacoustic transducer in accordance with the present invention comprises a perforated backplate having a plurality of upstanding parallel ribs between which conductive surfaces are situated.  The conductive surfaces are electrically interconnected with one another and with a contact surface on a relieved shoulder at one end of the backplate.  This shoulder is engaged by a bifurcated contact spring that (1) electrically connects the conductive surfaces to the input of an integrated preamplifier circuit deposited on a substrate and (2) holds the substrate in place on the underside of the backplate.         An electret diaphragm having a metallized surface is tensioned across the ribs of the backplate with the metallized surface facing away from the backplate, and while so tensioned, the ends of the diaphragm are clamped against the backplate by a conductive intermediate member that makes electrical contact with the diaphragm.  The intermediate member is held in place by a conductive spring member that wraps around the sides of the foregoing assembly and presses the intermediate member and the substrate toward one another.  The spring member provides the clamping force necessary to retain the desired tension on the diaphragm and at the same time further secures the substrate in place.  In addition, the spring member includes a terminal that is located in engagement with the ground lead of the preamplifier circuit and thus in combination with the intermediate member provides a conductive path to ground for the conductive surface of the diaphragm.  Finally, the spring member serves to provide additional electro-static shielding for the electret.

Abstract: ABSTRACT OF THE DISCLOSURE          A vehicle for distributing straw or like material from spirally wound, cylindrical bales (so called "round" bales), the rear end of the vehicle having a bale support comprising three transverse rollers, or a combination of a slide and two rollers, with open spaces therebetween.  With three rollers, the front and rear rollers are at the same level, and the central roller is below this level, so that the three rollers can cradle a bale while rotating this to feed the straw from the bale.  The rollers are rotated by drive means geared to the vehicle engine or wheels, and are arranged so that the peripheral speed of the rollers decreases towards the rear end of the vehicle so as to assist in loosening the straw as it moves from the front to the rear rollers.  The middle and rear rollers have blunt projections for frictionally engaging the straw, but these do not cause shredding of the straw.  The vehicle may have a platform in front of the bale support, for storing a second bale.  Also, the structural members which hold the rollers may be made tiltable so that the roll support can be brought to near ground level to facilitate loading of a bale onto the support.
