Abstract: A fluid delivery system is operative to deliver a high viscosity and/or a highly abrasive fluid at a preselected pressure. The system does not incorporate any pressure regulator disposed in contact with the pressurized fluid. The system includes a fluid supply which retains and dispenses a fluid, a source of compressed gas, a fluid delivery line, and a ratio pump which is in fluid communication with the fluid supply, the source of compressed gas and the fluid delivery line. The ratio pump is operable, when energized by a compressed gas, to pump fluid from the fluid supply through the fluid delivery line at a high pressure which is proportional to the pressure of the compressed gas supplied to the pump. The system includes a pressure transducer disposed so as to sense the pressure of the fluid in the fluid delivery line and supply a control signal corresponding to that measured pressure.

Abstract: A method for coating an article, including the steps of: (a) coating a surface of the article with an unsolidified resin composition that, upon solidification, forms a polymeric matrix on the surface of the article; (b) applying particles of rubber to the coated surface prior to solidification of the resin composition; and (c) causing or permitting the resin composition to solidify on the surface to form the polymer matrix with the rubber particles embedded therein. Also, an article coated by the method. In a preferred embodiment, the article is a hockey stick.
