Abstract: A tannin stain inhibitor and method of blocking tannin stain migration within wood or wood composite substrates uses an aluminate based chemical composition. The aluminate based complex chemical composition is incorporated into a conventional coating product, which when applied to a wood or wood composite substrate, exhibits improved tannin stain inhibiting properties.

Abstract: A non-toxic chemical composition inhibits corrosion in metal substrates. The composition contains a Phosphorus compound, comprising an acid and a metal selected from the group consisting of an alkali, alkaline earth, or transition metal. The composition also contains a Boron compound comprising an acid and a metal selected from the group consisting of an alkali, alkaline earth, or transition metal. A process of making the chemical composition comprises the steps of filling a mixer with 30-60% by weight of hot water and adding 10-20% by weight of barium carbonate or strontium carbonate, 10-20% by weight of phosphoric acid (75%), 5-15% by weight of lime, and 10-20% by weight of Boric acid; mixing the said contents for 10-15 minutes to create a wet slurry; pouring said wet slurry into an attrition mill for 15-60 minutes; drying said wet slurry and milling said wet slurry to an average particle size of 1.0-2.0 microns to form a dry pigment; pushing said dry pigment through a 325 mesh sieve.

Abstract: A compact gerotor pump having reduced axial dimension has an external fixed pump body in which a rotor and annulus set is housed. A drive shaft is provided that is neither fixed nor journalled directly by the pump body. The shaft is secured to the rotor within the body and extends through an opening in an end wall of the body and is secured to the hub of an external drive gear that is journalled by the housing for driven rotation of the drive gear, shaft, and rotor relative to the pump body.

Abstract: A gerotor pump comprises the usual lobed annulus 30 containing the lobed rotor (not shown in FIG. 2) which is journalled on cylindrical boss 36. The boss is free to turn on the eccentric pin 38 between positions controlled by limit pin 42 encountering end abutments. This enables the pump to automatically adjust to the variable direction of drive of the annulus--in this case via coupling 32--so as to be unidirectional in fluid output via flow passages 16 18.

Abstract: Oil pump manufacture is simplified by providing the pump body with a planar unstepped face and achieving radial location by the provision of a bush 22 (FIG. 2) on the pump driven shaft 14, which bush is received in the counterbore 24 of the part journalling the drive shaft 16, i.e. the cylinder block adjacent the end of the drive shaft (crankshaft).
