The present inventors have surprisingly discovered that phytic acid tenaciously precipitates with soluble metals in food or fuel ethanol-processing fluid, producing insoluble organometallic salt deposit or scale on the processing equipment that must be removed in order to facilitate further ethanol processing. The present invention relates to converting phytic acid salts or phytates to inorganic phosphates to improve metal solubility and reduce deposition within processing equipment.

Compositions for inhibiting the corrosion of metals in contact with an aqueous system are provided. The corrosion inhibiting compositions may be used to maintain effective amounts of (1) an amino acid-based polymer, such as a polyaspartic acid compound, and (2) a dispersible and/or soluble tin compound in the aqueous system. The corrosion inhibiting compositions include the amino acid-based polymer and a dispersible and/or soluble tin compound and may optionally include a polycarboxylic acid chelating agent and/or a carboxylate/sulfonate functional copolymer.

Corrosion inhibiting compositions

Methods for inhibiting the corrosion of metals in contact with an aqueous system are provided. The method of inhibiting corrosion includes maintaining effective amounts of (1) an amino acid-based polymer, such as a polyaspartic acid compound, and (2) a dispersible and/or soluble tin compound in the aqueous system. The corrosion inhibiting components of the treatment may be added simultaneously or separately into the water of the aqueous system, i.e., provided either in a single treatment product or as separate products. Such a corrosion inhibiting method may optionally also include adding a polycarboxylic acid chelating agent and/or a carboxylate/sulfonate functional copolymer to the aqueous system.

A pick hole plug for sealing an opening in a manhole cover and the process for using such plug. The plug is formed from a soft uncured rubber polymer which has a larger diameter than the hole which it is to seal. The plug is compressed by hand and inserted into the pick hole. The plug deforms to conform to the shape of the sides of the pick hole and cures over a period of time as the heat and sunlight contact it.

A gasket secured to the cover frame of an underground vault. The vault is of the type having a precast underground portion and an upper opening including a steel cover frame with a horizontal, flat surface to which the gasket is adhered. The gasket has a plurality of ridges along its inner edge, a flat center portion wherein the bolt holes are located and an outer ridge adjacent the bolt holes but separated from the outer edge.

An attachment for a framer's square which permits the framer's square to be self supporting on a flat, horizontal surface. The attachment has an elongated support bar with two clips which may be inserted over a blade of a framer's square. This attachment, when inserted on the inner edge of the framer's square, facilitates the scribing of a right-angle line to a rounded edge and when placed on an outer edge, permits the square to be free standing.

An improved gasket for use with manhole covers. The gasket is of the type which is fabricated from rubber and is held in a circular groove formed in the flat cover support surface of a cast iron frame of the type which holes a manhole cover. The manhole cover fits in the frame and rests on the gasket. The improved gasket has a vertical portion which is generally rectangular which fits into the circular groove. The gasket also has a horizontal portion which extends beyond the groove and onto the flat cover support surface of the frame.

A split elastomeric ring for repairing and sealing electrical connection boxes of the type commonly referred to as potheads. The ring has an elastomeric body and a central opening. A slit is provided in the body of the ring so that it may be opened and inserted around the cable at the base of the pothead. A silicone sealant is placed between the ring and the pothead and the ring holds the sealant against the cable and the base of the pothead body.

A relatively inexpensive but highly reliable electrically powered hose winding mechanism, particularly well adapted for rewinding auxiliary fire hose and the like. In the disclosed perferred embodiment, a smooth horizontally disposed rolling table has a free rolling hose guide means located near its outer edge, and a flush mounted wind plate means centrally located in an opening near its center. A pivotally mounted conventional electrical motor applies the power through pulleys and belts and a special pivotally mounted intermediate speed reduction means to allow reduction in r.p.m. from a range utilized in a conventional small electric motor to a range suitable for winding of hose. A variable speed control is preferably provided to assist the operator, and a special garden hose adapter is disclosed.
