Abstract: A push-in wire connector having a sealant therein to enable formation of a waterproof electrical connection by axial insertion of a wire into a chamber contained an electrical conductor protected by the sealant with the electrical conductor displaceable into a waterproof electrical contact with the wire while both the conductor and the wire remain in the presence of the sealant.

Abstract: A linear vibrator having an internal cylindrical bearing surface forming a chamber therein and a fluid inlet to direct a fluid into the chamber with a one piece piston slideable located therein with the piston simultaneously rotatable and axially displaceable therein with the piston including a static port to bias the piston and thereby induce piston oscillation when fluid is introduced into the vibrator.

Abstract: A vibratory plate screen having a first end for quickly mounting in a vibrator housing, an intermediate region with openings therein and a securement end that allows one to quickly secure a vibratory plate screen in a vibratory housing. In addition, the screen is sufficiently flexible to enable one to mount the vibrator screen in a curved condition or stressed condition so that the inherent tensile strength of the material assists in holding the vibratory plate screen in position. A further feature of the invention is the quick removal and securement of the vibratory plate screen.

Abstract: A dispenser system that takes high pressure fluid such as a high pressure water source and reduces the volume flow of the high pressure water as it flows into a dispenser with the dispenser having a low pressure outlet, which offers negligible fluid resistance in comparison to the inlet fluid resistance to the dispenser, thereby ensuring that if a dispenser cap is accidentally removed from the dispenser while the unit is in operation the water will not spray out into and onto the user. The dispensing system includes a removable cartridge carrier with adjustable openings and a dispenser housing that one can maintain a uniform flow pattern under different flow rates to provide for a predicable control of a dispersion rate from a dispersant located in the system and a method of predictably changing the dispersion rate of a dispersant.

Abstract: A cathodic protection system wherein a metal structure is electrically connected to a sacrificial anode through a self encapsulating wire connector that can be assembled by unskilled persons and can be maintained in a protective condition around an electrical junction to enable the electrical junction to protected from an underground environment.

Abstract: A decoder system and a direct bury splice kit for in situ encapsulation of an electrical wire and wire connector wherein the encapsulation minimizes separating forces between the joined wires in the wire connector.

Abstract: A user friendly system that permits an unskilled person to quickly add dispersant material to a fluid system with the user friendly system utilizing operator evident dispersant carriers such as drawers, hangars or insertable cartridges.

Abstract: A vibratory feeder for delivery of material in different directions comprising a set of vibrators that are vibrationally isolated from each other to enable activation of one of the vibrators to vibrationally direct conveyable material in a first direction and activation of another vibrator to vibrationally direct conveyable material in a second direction while at the same time the vibrators are vibrationally isolated from each other through a set of isolators.

Abstract: A dispenser or dispensable material for external attachment to a mobile surface cleaning device, mobile surface cleaning device provides an aftermarket apparatus and method for both on-the-go cleaning and on-the-go delivery of dispensable materials into the body of water with the dispensable material mounted either on a downstream side of the mobile surface cleaning device or spaced from the flow path through the mobile surface cleaning device.

Abstract: A lightweight, inexpensive, corrosion proof, utility pump having a flexible member forming a sliding interference fit with a pump rod with the flexible member confined between a pump rod bushing and an end cap to prevent leakage and a method of converting an inexpensive utility pump from a leaking condition to a non leaking condition without having to modify the existing components of the utility pump.

Abstract: A control system comprising a timer based controller and a valve wherein the timer-based controller has a fixed period and the timer based controller regularly cycles the valve between a first condition and a second condition with the first portion of the cycle directing a first flow of water through a dispensable material and the remaining portion of the cycle directing a lesser flow of water through the dispensable material.

Abstract: A dual filter apparatus and a process of making a dual filter apparatus that minimizes disruption to the normal flow pattern through the filter apparatus by forming a porous medium suitable to carry a fluid activator and placing an activator proximate the porous filter medium for in situ fluid treatment and removal of debris from the fluid by screening action of the porous filter medium that entraps debris thereon.

Abstract: A twist-on wire connector having a finger friendly unbiased cushioned cover that covers not only the normal hand gripping region but at least part or all of the normal non-hand gripping region of the twist-on wire connector so that regardless of the way the twist-on wire connector is grasped the user fingers engage the cushioned cover to inhibit finger and hand injury and fatigue from repeated securement of twist-on wire connectors to electrical leads and a method of making a twist-on wire connector with a cushioned cover by placing a soft to the touch material on the exterior surface of the twist-on wire connector.
