  • Patent number: 9761106
    Abstract: An anti-intrusion device simulates the sound of a round being chambered in a pump shotgun using metal parts which strike one another. A striker carriage is movably disposed in a sound box for moving between first and second positions to engage metal striker plates and metal striker tabs against sound plates to simulate the chambering sound. A mangle drive assembly is mounted atop the sound box for moving the striker carriage between a forward position and a rearward position, powered by a stepper motor which is actuated to rotate a controlled axial displacement when a trigger mechanism is tripped. Preferably, the trigger mechanism is provided by a light mean sensor in which the light beam is broker by an intruder passing a selected entry point.

  • Patent number: 8562059
    Abstract: An improved mechanism for a movable seat for use on a bi-directional work vehicle that laterally shifts the lower seating surface as it is pivoted between raised and lowered positions to increase clearance adjacent to the seat to improve operator ingress and egress to the vehicle operator platform. The incorporation of a biasing mechanism enables the seat mechanism to automatically reposition the seat for maximum ingress/egress clearance when the vehicle operator rises from the seat.

  • Patent number: 8327766
    Abstract: A timing element for an initiator is made from a reactive polymeric material such as, e.g., a glycidyl azide polymer. The reactive polymeric material may include pulverulent oxidizer additives, such as ammonium, perchlorate and/or ferric oxide. The oxidizer additives are used to increase the rate of reaction and the output spark of the polymer material. The timing element serves to delay the travel of an initiation signal between an input, such as a signal transmission input line, and an explosive output charge, for a predetermined period of time, usually about 5 to about 10,000 milliseconds, e.g., about 9 to about 9600 milliseconds.

  • Patent number: 6105315
    Abstract: A mausoleum and method of constructing a mausoleum. The mausoleum may include plurality of vertically extending walls supportable on a surface, wherein at least one vertically extending wall has a plurality of cells integrally formed therein. At least one cell is substantially filled with a filler material. A roof is supported on the vertically extending walls and cooperates with those walls to define at least one crypt niche having at least one open end. A closure panel corresponding to each open end of each crypt niche is provided. One or more cells within the walls may be unfilled to serve as drain and/or vent passages for each niche. Shelf assemblies may be supported within each niche to form chambers for receiving caskets therein. Each shelf may have open cells formed therein which can communicate with open cells within the walls. A lawn crypt manufactured from similar materials is also disclosed.

  • Patent number: 5993935
    Abstract: A composite article is provided having covalently reactive particles incorporated in a continuous, porous matrix. The reactive particles have surfaces of covalently reactive functional groups capable of directly forming covalent chemical bonds with ligands without need for an intermediate activation step. An adduct composite article is also provided comprising a continuous, porous matrix and derivatized particles dispersed therein. The derivatized particles comprise a direct, covalent reaction product of ligand with the covalently reactive particles. Methods of making and using the composite articles and adduct composite articles are also provided. Preferred covalently reactive functional groups are azlactone-functional groups of the formula: ##STR1## wherein: R.sup.1 and R.sup.

  • Patent number: 5595689
    Abstract: A polymer blend according to the invention of the type including an intrinsically conductive polymer disbursed in a matrix selected from thermoplastic polymers, monomers, polymerizable precursors and combinations thereof is improved by an amount of a non-polymeric polar additive having a boiling point greater than about 100.degree. C. at 760 mm pressure and greater than the processing temperature of the matrix polymer incorporated in the polymer blend, in an amount sufficient to impart an electrical conductivity to the blend which is greater than that of the blend without the non-polymeric polar additive. A blend according to the invention includes a matrix material selected from thermoplastic polymers, monomers and polymer precursors and combinations thereof, and an intrinsically conductive polymer and a non-polymeric highly polar additive, disbursed into a polymer blend and having a conductivity of greater than about 2.5 S/cm.
