Abstract: An addition of a fine adjustment flow-control mechanism that produces changes in fluid flow in increments of 0.1% or less, to any configuration high pressure fluid flow control valve that employs an axial valve stem and a rotatable rough control knob that moves the stem axially in increments of 1.0% or more, opening the valve flow chamber to fluid flow. The valve stem is designed and driven so that it does not rotate or twist, and particular provision is made to eliminate fine control drive tolerance build-up. These aspects produce a very high degree of adjustment accuracy during operation of the flow control valve.

Abstract: A pad for scrubbing is attached to the head of a mop holder by a removable adhesive means such as VELCRO, producing a combined mop and scrubber holder for dual use cleaning and removing need for a separate scrubber holder. The pad may be easily removed and replaced when it is worn out. For cleaning applications requiring a separate scrubber tool, a removable scrubbing pad is attached to the end of an applicator handle, using a removable adhesive means such as VELCRO. Any worn out scrubbing pad can be easily removed from the applicator handle and replaced.

Abstract: A non-spillable liquid toothpaste dispenser which stands upright for normal use, but can be used in any orientation. The dispenser is made of rigid plastic and comprises a case, a cap and a cartridge containing liquid toothpaste inside the case. Inside the top of the cartridge is a sliding valve having semicircular doors at its top. In use, a toothbrush head is pushed through a flanged hole in the top of the case, through the valve semicircular doors and into the liquid toothpaste. When the toothbrush is withdrawn, excess toothpaste is wiped off by the doors and the doors return to their normal closed position. The valve doors will also be made to close if any liquid toothpaste flows toward and impinges on the valve. In addition, a tight plug is provided in the cap to ensure no leakage of liquid when the dispenser is packed.
