Abstract: A coupling device for fueling automobile gasoline tanks is disclosed and claimed. The coupling has two parts: a cap assembly (female half) and a nozzle assembly (male half). Little or no spillage occurs due to opposing flush faces of the female main valve and the plug of the male. The cap assembly is affixed to an existing gasoline tank (fuel storage tank) or alternatively can be supplied as original equipment on a new automobile. Fuel vapor is extracted from the automobile fuel tank with high efficiency and returned to the pumping station for storage and/or reprocessing. Vapors and/or liquid fuel are extracted through the portion of the gasoline tank cap assembly which resides within the tank. Apertures in the cap assembly communicate with an annular passageway which removes the vapors to ports which mate with peripheral apertures in a concentric nozzle having an outer sheath and an inner fluid conduit.

Abstract: A method and package for controlled metered dispensing of a fluid product contained in the package having a metered dispensing system, each time the package is opened or uncapped are disclosed. By the present method and package, the maximum amount of product that can be dispensed is limited to a single metered dose after each uncapping of the package. Specifically, the metered dispensing system is configured to allow dispensing of only a single metered dose of a liquid, viscous liquid, gel, paste, or semi-solid product contained in the package and to prevent further dispensing of additional doses of product until at least one specific and deliberate step is taken that re-activates or re-engages the dispensing system. Such deliberate step is preferably one that occurs through natural use of the package, such as re-capping the open package after one single dose has been dispensed. Only after the open package has been re-capped can the next dose of product be available for dispensing.

Abstract: A workbench with an adjustable height top dually engaged by twin standards with each standard having a single pawl-like structure laterally extended from front to back. The pawl mechanism in each standard is a laterally extended round rod engaging a vertical array of rounded ratchet apertures at the front and back end of the top. A novel safety mechanism to prevent inadvertent disengagement of the rod from the ratchet apertures is a combination of a tension spring connected between a chain and a foot actuator pedal. This spring prevents accidental release of the rod by absorbing unintentional or inadvertent minor force applied to the pedal. The rod-like structure or pawl provides superior structural rigidity for the bench when restricted with rear shims to rotation into the ratchet slots at an angle &agr; between less than about 45 degrees and greater than about 10 degrees.

Abstract: In a coating film transfer tool, a tape is unwound from a supply reel, fed over a transfer head, and wound onto a take-up reel driven from the supply reel by a drive mechanism having slippage. Instead of setting the average slipping torque at a high value, or minimizing its variations, to prevent it from falling below the winding threshold, the initial slipping ratio is set at a value of at least 34%. This avoids slackening of the tape without the need for close manufacturing tolerances or lubricants, and without causing a condition in which excessive force is required to wind the tape onto a take-up reel in the later stages of the tool's useful life.
