Abstract: FISH CULTURE TANK     Abstract of the Disclosure A cylindrical fish culture tank adapted for a self-cleaning operation.  Oxygenated water, whether fresh, recycled, or a mixture of fresh and recycled, enters a tangential inlet near the bottom of the tank and develops an upwardly flowing spiral action.  The spiral action, assisted by swimming movements of fish, causes solids to gravitate towards the center of the tank.  The bottom of the tank is shaped as an inverted obtuse cone with a screened, normally closed drain opening in the center. At the top of the tank is a screened overflow drain, from which water is normally withdrawn for discharge or for cleaning and filtering.  About once a day, the fish culture tank may be cleaned by removing the solids through the screened drain. An airlift assembly may be connected to the drain for recovery of live fish when the screen is taken off the drain.  At transfer or harvest time, the live fish may be drained from the bottom of the tank and recovered.

Abstract: Abstract of the Disclosure A fabric to have a coating of controlled thickness applied to its upper surface moves between a supporting roll and a supporting plate.  The lower surface of the fabric contacts the supporting roll and supporting plate but is unsupported therebetween.  Between the supporting roll and plate, the moving fabric is depressed by a blade extending across its width.  Near to the blade and between this blade and the supporting plate, a coating is applied to the upper surface of the fabric.  A gauging device adjacent to where the coating is applied controls the thickness of the coating.  The distance between the blade which depresses the fabric and the supporting plate should be several orders of magnitude greater than the distance between this blade and the gauging device.  Any variations in fabric thickness as the fabric passes over the supporting plate would cause corresponding variations in the coating thickness if the coating were being applied over this plate.  Controlling the coating thickness at the gauging device reduces the coating thickness variations which would occur if the coating were applied over the supporting plate by the factor of the distance between the blade which depresses the fabric and the gauging device divided by the distance between this blade and the supporting plate.

Abstract: STRUCTURE AND FABRICATION METHOD FOR INTEGRATED CIRCUITS    WITH POLYSILICON LINES HAVING LOW SHEET RESISTANCE                  ABSTRACT OF THE DISCLOSURE         A method and structure for polysilicon lines which include a silicide layer for providing a low sheet resistance. The invention may be employed in a polysilicon gate MOSFET process for integrated circuits as well as other integrated structures.  In the method a first layer of polysilicon is deposited followed by a deposition of a metal of the silicide forming type. Another polysilicon layer is then deposited on top of the silicide forming metal to produce a three layer structure.  The three layer structure is subjected to heat, for example, during the reoxidation step in a gate fabrication process, the metal reacts with the polysilicon at two reaction fronts to form a silicide.  The resultant silicide has a much lower resistivity than doped polysilicon and therefore provides a second conductive layer which can be used more compatibly and efficiently in connection with the normal metal layer employed in integrated circuits to give a two-dimensional degree of freedom for the distribution of signals.

Granted: 1982-04-13
Abstract: Hydrolyzed wheat starch is an effective flocculant in destabilizing dilute as well as thick sludge suspensions. This wheat starch is equal to, or better than, the synthetic polyacrylamide flocculants in destabilizing sludge suspensions, particularly when used in the treatment of bituminous tar sands tailings and phosphate slimes. The hydrolyzed wheat starch is especially effective when first contacted with metal salts such as CaAlPO4, and most particularly when first treated with a combination of CaAlPO4, formed in situ, and a lower aliphatic alcohol. In a further embodiment of this invention it has been found that when cement is added together with the aforedescribed composition, there is achieved improved permeability and shear strength of the resulting sludge.

Abstract: ABSTRACT       Grit is removed from liquid sewage by flowing such sewage into a settling chamber and causing the sewage to flow in a toroidal pattern around the periphery of the chamber.  Grit falls to the floor of the settling chamber and passes radially to and then through a central opening into a grit collection chamber therebeneath.  Organic solids are kept in motion in the toroidal flow pattern, or lifted from the settling chamber floor into such flow pattern, and are discharged through an outlet adjacent the upper surface of the liquid in the settling chamber.  Toroidal flow is created and maintained by obstructing the tangential flow path of incoming sewage with a baffle which blocks the tangential inlet and has an edge extending above the upper surface of the liquid.  A propeller rotating about a vertical axis in the center of the chamber is adjustable so as to keep the contents of the chamber impinging against the baffle as they flow around the tank in the toroidal pattern.
