  • Patent number: 5448443
    Abstract: A power conditioning device protects sensitive electronics in modern electronic equipment from disruption or destruction caused by transients which can cause both induction and injection currents into the grounding system of the electronic equipment. This device nominally comprises an isolation transformer and a ground impedance between the earth ground connection from a distribution panel and the safety ground connection to the powered equipment. In addition, this device may also comprise a voltage clamping device such as an MOV and a capacitive filter to provide a complete power line conditioner. This device may be used in systems with guarded or driven grounds, or in a system with a high voltage reference to safety ground. In addition, ground conditioning can be added to a Ground Fault Circuit Interrupter (GFCI) to attenuate ground surge currents.

  • Patent number: 5443183
    Abstract: A check valve disposed to fit between paired outlet nozzles of adjacent cartridges of a multiple component reactive fluid system and a mixing tube sealed over the nozzles and having a single outlet for discharging the mixed reactive material. The check valve has a flat portion and an upstanding wall formed therefrom, each sized and shaped to seat over the nozzles and against the mixing tube. Openings formed in the flat portion commumicate with the nozzles and provide separate flow paths of the respective materials to the mixing tube. Check structure as separate flaps integral with the wall cover and close the openings. The internal flap resilience normally holds the check valve closed, but allows flap flexture to open the outlet nozzle when the cartridge pressures exceed the closing forces. The check valve restricts back flow of either material into either outlet nozzle.

  • Patent number: 5441175
    Abstract: The disclosed universal tool has a front plate with an open ended slot extended from near the front wall center, with the front wall defining the slot having one thickness and the wall spaced from the slot having a greater thickness. The front wall further can be mounted in the tool in two different arrangements, respectively flipped over 180 degrees. This tool thereby accommodates different paired material cartridges, both as to size to give different component ratios and as to constructions, such as from different manufactures. The cartridges further can be shifted along the slot as needed to remain parallel to the plunger rods that drive plungers through the cartridges to cause material discharge therefrom. The stable front wall-cartridge cooperation also holds the cartridge and easily allows rearward plunger withdrawl from the emptied cartridge.

  • Patent number: 5433354
    Abstract: The surface port device has a tube with a throughbore between its inlet and outlet ends, and an enlarged flat base at the outlet end, suited to be bonded by adhesive securely to a structure surface with the tube bore aligned over a surface crack. The inlet tube end is stepped, having several adjacent generally cylindrical axially extended land areas of progressively smaller diameters I.D. in moving downstream toward the outlet end. The land areas are sized both in diameter and axial length to correspond to certain more common generally cylindrical land areas of conventional available material mixing/dispensing tubes proximate the outlet nozzles thereof. This allows the establishment of a mechanically sound leakproof separable joint between the material dispensing tube end the surface port device. A captive check ball in the tube bore automatically can be shifted between opening the port bore or closing it to preclude material backflow.

  • Patent number: 5386931
    Abstract: A material dispensing tool has restraining and rear walls spaced apart to receive a material cartridge therebetween, and has an elongated rod supporting a plunger for movement between the walls and within the cartridge. A power ratchet mounted rearwardly of the rear wall over the elongated rod incrementally moves the elongated rod. Linkage including a spring concentrically arranged on the elongated rod effectively couples the power ratchet relative to the restraining wall, whereby the elongated rod can be resiliently biased by the strained spring. Output movement of the elongated rod relative to the power ratchet can thus be substantially independently of the plunger movement relative to the cartridge, the strained spring generating nearly uniform resilient plunger forces to discharge material from the cartridge.

  • Patent number: 5263614
    Abstract: The improved dispensing tool has linkage that includes a spring connected between a power ratchet and a wall restraining the material cartridge against plunger movement through the cartridge for discharging material, thereby allowing resilent independent plunger movement within the limits of spaced stops. When subjected to only static force conditions, the spring bottoms the linkage solid against one of the stops, to provide in-unison forward indexing of the plunger and ratchet drive rod. In the event plunger displacement occurs that is less than the expected in-unison indexing, the one linkage stop is gapped to subject the spring to additional dynamic force conditions that biases the plunger resiliently and continuously in the forward direction toward the restraining wall, up to maximum dynamic force conditions that bottoms the linkage solid against the other stop. The dynamic spring forces move the plunger forwardly within the cartridge for discharging the contained material.

  • Patent number: 5251752
    Abstract: The disclosed invention uses an open-top vessel for supporting a water rinsed razor and its blade, the vessel being filled with mineral oil to a level above the blade. Different mechanisms are used for holding the razor and for moving the submerged razor and mineral oil relative to one another. One mechanism comprises mechanically gripping the razor and moving it through the mineral oil contained within the vessel. Another mechanism comprises moving the mineral oil, by pumping it or vibrating it, relative the razor. The disclosed invention also uses a portable storage vessel having a brush bristle outlet for the mineral oil, and brushing the mineral oil onto the blade manually. In using all such mechanisms, the razor blade is effectively coated with the mineral oil to isolate it from the atmospheric air and thereby protect it from dulling caused by corrosion.
