  • Patent number: 5320022
    Abstract: A method and apparatus are provided for reducing the recoil and muzzle climb from the discharge of a firearm. A hollow cylinder member having a front end with a restricted opening forming a gas chamber is attached to the muzzle end of a firearm and serves to rearwardly divert the highly pressurized gas produced from the combustion of gunpowder. The cylinder member is provided with rearwardly angled holes along both its top and bottom surface which act as jets to create a forward propulsive force from the expelled gas. This forward force counteracts and reduces the backward force of the firearm's recoil. By providing a greater ratio of top holes to bottom holes, thereby effecting a downward force greater than the upward force, muzzle climb can also be effectively reduced. The apparatus can be constructed for quick attachment to the muzzle of the firearm.

  • Patent number: 5244162
    Abstract: A method and apparatus for slitting and separating a wide roll of gasket material of varying thicknesses into narrower rolls of uniform thicknesses. A wide roll of gasket material is slit into a plurality of narrow rolls. Each roll is passed under a roller at a pressure simulating the working load pressure of the gasket. A thickness gauge and probe is employed to determine thickness of the material as it passes between the rollers. The web of material is cut when the thickness exceeds specified tolerances and the separated lengths are collated in separate rolls of uniform thickness. Gaskets are stamped or cut from the collated rolls and for quality control a gasket from a group of gaskets is measured for thickness under the simulated working load pressure. The thickness gauges employed in the rollers and quality control are calibrated against one another to ensure uniformity of measurement.

  • Patent number: 5234325
    Abstract: Apparatus for windshield glass repair is provided. A cylinder having internal chambers is equipped with a piston head plunger at a top end and has a mounting device at a bottom end for securing a tight seal over a crack in a windshield. The withdrawal of the plunger creates a vacuum and allows for air to be pulled out of the crack, while a side stem in communication with the cylinder allows resin filler material to be introduced and forced into the crack. Air pressure is equalized by opening the side stem, whereupon the plunger can be depressed to force the resin filler into the crack. The mounting supports allow for quick connect and disconnect of the cylinder. The side stem obviates the necessity of removing the cylinder for re-filling of resin material whereby any length crack can be repaired without breaking the tight seal on the crack.

  • Patent number: 5215637
    Abstract: An apparatus and method are provided for surface treating the inside surfaces of hollow or three dimensional plastic objects. While the invention will be described with respect to plastic objects, it will be understood that other objects having a high dielectric strength, such as ceramics, cardboard, paper and wood, may be similarly treated. The surface treating is effected by selectively directing a high voltage plasma field to a selected interior surface of the object to enhance adhesion of various glues, inks and the like. The plasma field is generated in the interior of a tunnel directed into an opening of the hollow portion of the object to be treated. A specially designed electrode is supported from the opening to direct in a controlled manner the field to the selected interior area of the object to be treated. The electrode is supported form a high dielectric shield covering a central area of the opening to direct the plasma field around the shield to a laterally extending electrode below the shield.

  • Patent number: 5207805
    Abstract: An improved cyclone separator and method of construction are disclosed. Such cyclone separators are employed for separating particulates from hot gas entering the separator barrel through an axially disposed slot in its periphery. An improvement in efficiency and recovery of very small particulates is achieved by making the slot very narrow so that the particulates enter the barrel very near its inner surface, thus having less distance to travel under centrifugal force in order to reach said inner surface. In accomplishing this objective, however, it has been discovered that, for the particular inlet gas velocity selected, the structure under certain design conditions will act as a cavity resonator with the characteristic frequencies of the cavity matching the frequency of the incoming gas as it rotates in the barrel, thus causing the structure to function as a resonator thereby destroying the efficiency or, in extreme cases, having catastrophic results (in the mathematical sense).
