Abstract: A one-hand engageable vacuum tool connection assembly for connection to a commercial vehicle vacuum system that includes: a vacuum tool connection assembly hose having a first end and a second end; an upper assembly and a lower assembly having a tool connector where the tool connector engages a second end of the lower assembly swivel cuff and is typically adapted to receive one or a plurality of different types of vacuum tools. The vacuum tool engagement assembly is typically free of any flapper valve, metal or spring biased elements.

Abstract: The present disclosure includes a vacuum stall canopy assembly for a car wash system having a first post assembly having a base leg permanently attached to the ground, a beam attached to the top of the first post assembly, a roof assembly disposed on an upper portion of the beam, a debris separator disposed on the beam, the debris separator having a first side and a second side, a main airline fluidly connected to the debris separator and configured to be connected to a source of vacuum suction, a first hose on the first side of the debris separator, and having a first nozzle on a distal end of the hose from the debris separator, and a second hose on the second side of the debris separator, and having a second nozzle on a distal end of the hose from the debris separator.

Abstract: A vehicle vacuuming system that includes: a vacuum housing having an air filter, a motor within the interior volume of the vacuum housing wherein the motor supplies air suction power to a vacuum air intake distal from the motor and through a vacuum hose operably engaged with the vacuum housing, and an air outlet proximate the motor; and a pressure notification system chosen from the group consisting of a light, a speaker, a mobile application, and combinations thereof operably connected to a pressure sensing system associated with the vehicle vacuuming system.

Abstract: A vacuum cyclonic separator that includes: a main body having a top surface with an air outlet, a bottom perimeter defining a bottom aperture of the main body, at least two downwardly facing air inlets and at least one side wall extending between the top surface and the bottom portion and shaped such that air received within an interior cavity of main body moves in a cyclone and wherein the at least two downwardly facing air inlets are in at least substantially the same plane as the bottom perimeter of the main body; and a dump valve assembly capable of being opened and closed with one hand where the dump valve is engaged with the bottom portion to seal the bottom aperture of the main body.

Abstract: An improved sunglass lens laminate has first and second lens portions joined by an adhesive, wherein the adhesive at least one of (1) an ultraviolet absorber in an amount sufficient to block substantially all solar radiation up to about 400 nm, and (2) a dye to provide selected visible light transmission characteristics to the laminate. In a preferred embodiment, a polarizing film is disposed between two lens portions to form a polarizing sunglass lens laminate.

Abstract: An improved sunglass lens laminate having first and second lens portions joined by an adhesive, wherein the adhesive contains sufficient ultraviolet absorber to block substantially all of the UVA radiation in sunlight. In a preferred embodiment, a polarizing film is disposed between two lens portions to form a polarizing sunglass lens laminate.

Abstract: An improved method for inhibiting corrosion of precious metal plated objects is provided wherein a thin dichromate film coats the precious metal outer surface and fills the precious metal outer surface pores using either immersion or electrolytic methods employing passivation plating techniques.

Abstract: A self-clocking binary data acquisition and transfer system in which each t of any data stream is divided into four time periods such that both 0 and 1 data bits are high during the first time period and a 0 will go low after the first time period and a 1 will be low after the third time period. The first, second and third time periods are used for transmission of information and the fourth for initialization.
