Abstract: A liquid level sensor probe for determining liquid level within a vessel, the liquid level sensor probe comprising at least one light source positioned for emitting radiant energy; at least one photosensor positioned for detecting an amount of radiant energy received from at least one light source wherein a change in the amount of radiant energy as detected by at least one photosensor is indicative of a change in liquid level within the vessel; at least one light shield positioned between at least one light source and at least one photosensor wherein at least one light shield prevents radiant energy from directly hitting at least one photosensor; and encapsulation material.

Abstract: A method, system and tool for decorating vertical surfaces comprising the steps of providing a medium comprised of cement, a light weight aggregate, silica sand, fused silica, monofilament fine denier fiber, liquid polymer resin, and water; applying a bond coat of a primer made from concentrated liquid polymer to the vertical surface; allowing the bond coat to become tacky; applying the medium to the bond coat on the vertical surface; allowing the medium to set forming a scratch coat; applying a liquid release agent to the scratch coat; applying the medium over the liquid release agent; and decorating the medium on the vertical surface.

Abstract: A method and article of preparing a synthetic solid surface material having a simulated burled wood effect in a pattern therethrough comprising the steps of: preparing a matrix of isophthalic polyester resin, alumina trihydrate (ATH), iron oxide pigments and pearlescent mica pigments, mixing said matrix completely in a vessel, catalyzing said matrix with methyl ethyl ketone peroxide (MEKP) in said vessel, placing said vessel containing said matrix into a vacuum for removing any trapped air in said matrix, removing said matrix from said vacuum, preparing a burling effect material which comprises polyester resin, ATH, iron oxide pigments, and pearlescent mica pigments wherein said iron oxide and pearlescent pigments are chosen to simulate the color of the grain of a wood to be simulated and are generally a darker color than said matrix and said burling effect material has a specific gravity slightly less than the composition of said matrix, catalyzing said burling material with methyl ethyl ketone peroxide (MEK
