  • Patent number: 8925579
    Abstract: A pressure relief valve for use with flexible containers is disclosed. The valve comprises a valve chamber, a valve chamber seat with an inlet gas port or ports to the interior of the container and a resilient diaphragm floating within the chamber. The valve seat is shaped with a generally flat diaphragm-engaging surface in a central area of the diaphragm where the inlet gas port(s) are located, and at least one surface that does not generally engage the outer portion of the diaphragm, such that a diaphragm floating in the valve chamber engages a central portion of the valve seat surface stopping the passage of gases in or out of the container before a certain pressure is reached, but permitting the passage of gases from within the flexible container as pressure builds, while preventing the flow of atmospheric gases into the container.

  • Patent number: 8342203
    Abstract: A degassing valve in a flexible container is disclosed. The valve includes a generally flat valve seat on a truncated generally dome shaped structure, and the valve seat is raised a height above the valve chamber base surface. A resilient, non-perforated, non-spring-biased diaphragm is inter-engaged upon the valve seat and overlaps the valve seat outer periphery. The valve seat engages a central area of the diaphragm that is not proximate the perimeter of the diaphragm, and the dome shaped structure has a sectional radius greater than the diaphragm radius. A well is recessed into the valve seat in a direction away from the diaphragm by a depth less than the height of the valve seat above the valve chamber base surface.

  • Publication number: 20110284536
    Abstract: A label type degassing valve with a vented flexible cover and a base with a central aperture. The base is adhered to the cover with an adhesive layer or coating that is positioned and shaped not to interfere with the vents. The vents are generally positioned off center in the cover. For the adhesive coating, there is a deactivated central region of the coating facing the base so that no part of the deactivated central region is adhered to the base and at least one of the vents is cut through the cover and through the deactivated central region.

  • Publication number: 20070214780
    Abstract: A submersible power plant 10 comprises a submersible enclosure 12 having at least one intake valve 16 for admitting water at high pressure from the surrounding sea into and air space in the enclosure. An air shaft from the air space 96 is in communication with the atmosphere for maintaining the air space at approximately one atmosphere. A pump for evacuating water collected in the enclosure includes a buoy 62 responsive to ocean swells. A piston shaft 58 connected to the buoy reciprocates in the center bore 60 of a vertical column 52 extending upward from the bottom of the enclosure. As the piston shaft rises inflow valves 72 admit water in the enclosure into a valve housing 70 in communication with the center bore. As the piston shaft falls water is discharged from the valve housing into the sea through a discharge valve 80 in the bottom of the enclosure.

  • Publication number: 20060071045
    Abstract: The Celltrekker is a kit that eliminates the sometimes cumbersome and restrictive access afforded by current cellular telephone (or similar sized object) conveyances or holders. Other holders contain clips, buckles, pockets, snaps, pouches, or other types of fasteners which may require the user to manipulate said fasteners in order to gain access to the cellular telephone or similar sized object. Using the Celltrekker as designed, the user may access the cellular telephone or similar sized object by simply grasping it and pulling it away from the belt-mounted (or otherwise mounted) patch of “loops”. The user may re-attach the cellular phone or similar sized object to the holder by simply pressing the “hooks”—equipped object to the holder containing the “loops”. Celltrekker, as designed, provides unfettered access and can be adapted to fit any flat-sided or slightly curved surface, keeping obvious parameters in mind.

  • Patent number: 6983698
    Abstract: A shaped charge explosive device which includes an axially symmetric body of explosive material, a liner lining the forward end of the body, and a detonator disposed at the bottom of the body. The liner has an apex disposed along the symmetry axis of the body and the forward end of the body contains a gas filled cavity which overlaps the apex of the liner. When the detonator detonates the explosive material, a detonation wave is produced that collapses the liner into a plurality of liner parts which are projected against an external target. The gas filled cavity shapes the detonation wave so that the detonation wave impacts the liner at the most favorable angle to transfer energy to the liner and maximize the effective penetration of the external target by the projected liner parts.

  • Publication number: 20050210608
    Abstract: A method and system for automatically loading foam pellets which clean fluid carrying passages, such as hydraulic tubing, into a pneumatic launcher. The pellets are automatically transferred from a storage sleeve into the pneumatic launcher for subsequent propulsion through the tubing. Interior walls of the passages are scrubbed clean as the pellets pass therethrough. In addition, the method and system can easily convert a conventional foam cleaning pellet pneumatic launcher from a manual loading operation to a fully automatic loading operation, thereby increasing overall productivity of the cleaning operation.

  • Patent number: 5939663
    Abstract: A method and apparatus are provided for selectively producing a coherent or ispersed jet pattern upon detonation of a shaped charge ammunition round. Multiple detonators are provided which may be arranged in a symmetrical or non-symmetrical pattern around or on the axis of the charge. Selection of a coherent or dispersed jet pattern may be provided by controlling the number and timing of detonators used. A coherent jet may be produced, for example, by actuating only one detonator along the centerline of the round. Dispersed jets in selected patterns may be achieved by actuating multiple detonators in different patterns.

  • Patent number: 5847312
    Abstract: A shaped charge device having at least a double confinement configuration d utilizing a standard shaped charge liner inserted into a hollow cavity in the inner explosive fill. The inner explosive fill is surrounded by an inner confining case which may be made from any metal, ceramic, or composite. The uniqueness of the present invention is the addition of an outer layer of explosive containing an outer confinement case. Also utilized in the device are a booster, and a detonator, held by a centering device, to initiate the device according to standard practice. The device acts to use the outer explosive as a tamping material surrounding the inner confining case material. This will delay the expansion of the inner confinement case and increase the pressure on the liner. Increasing the pressure on the liner will increase the kinetic energy of the resulting penetrator jet.
