Abstract: An airport security system for monitoring and securing airplanes stowed at various site airports within a security network is provided. Each of the planes is fitted with a transmitter or transmitters that transmit coded signals upon detecting an intrusion. In addition, the transmitters transmit periodic check-in signals. The signals are received by a receiver at the site airport, which conveys the coded signals to a local site main computer that, in turn, is connected to a central facility computer coupled to all of the site main computers within the network. If an alarm condition occurs or if an aircraft in the system fails to check-in at its designated time, appropriate alarms are generated and appropriate action taken. Aircraft can also be tracked by the central facility computer as they fly from one site airport to another within the network.

Abstract: An improved wood pulverizer is provided with a rotating disc studded with a plurality of curved tapered hammers. One or more anvils is secured to the pulverizer with the anvil having teeth and slots located adjacent the surface of the disc. The hammers of the rotating disc pass through the slots of the anvils as the disc rotates to tear and shard wood into bits and pieces for subsequent use or processing. The anvils of the present invention are formed with two or more useable surfaces so that the anvils can be removed, rotated, and replaced to present fresh cutting surfaces to the disc. Further, the anvils are formed by a series of bolted together anvil segments to allow replacement of only single segments in the event of damage.

Abstract: A small, lightweight, reusable marker buoy is provided for marking a selected location on a body of water. The marker buoy has a buoyant float formed with an upwardly open well within which is mounted a rotatable anchor line spool. A conduit directs anchor line from the spool, through the float body, and out the bottom of the float where it is attached to a weighted anchor. A spring biased friction plate within the well provides resistance to rotation of the spool and a nut that secures the spool on an upwardly projecting spindle can be tightened to press the spool against the friction plate with a predetermined force to provide a preselected resistance to rotation of the spool and thus a preselected tension on the anchor line. In use, the resistance is set to allow the weighted anchor to draw anchor line from the spool as the anchor sinks but to resist further deployment of anchor line from the spool due to wave and wind action after the anchor has fully deployed.

Abstract: A fuel dispenser is disclosed. The fuel dispenser has a housing which contains two chambers, one contains a computer and the other the hydraulic parts of the dispenser. Fiber optic cables connect a fiber optic switch which detects the cradling of a nozzle to a computer, and other fiber optic cables connected to a pulser signal the flow of fuel in the meter of the dispenser to the computer. The computer controls a liquid crystal display which prompts the customer to actuate keys on a keyboard adjacent to the display. A pivotal boot supported by a horizontal shaft receives the nozzle. This boot pivots to permit better access to the hydraulic area of the housing. The shaft, itself, is rotatable to actuate a switch to indicate, through fiber optic cable, to the computer that the nozzle is stored and to shut down pumping. A fiber optic pulser feeds light signals to the computer for indicating the flow of fuel through the meter.

Abstract: An improved astragal assembly for use with a double door installation includes an astragal strip secured along the vertical edge of the inactive door. A lock block is slidably disposed in at least one end of said astragal strip and can be moved between an extended position for securing the door and a retracted position for freeing the door. The lock block has a projecting bolt receivable in a receptacle in the door frame when the lock block is slid to its extended position. A gasket is secured to the end of the lock block and the bolt passes through an opening in the gasket. The gasket engages and seals against the door frame when the lock block is in its extended position. Gaskets are also provided on the sides of the lock block for engaging and sealing against the doors of the double door installation. When the doors are closed and secured in place, the lock block and gasket assembly prevents drafts from flowing under the door installation beneath the astragal thereof.

Abstract: The method and apparatus for reclaiming substantially pure sand from a heat treating furnace; wherein a casting with sand core and/or sand mold, comprising sand bound by a combustible binder, attached thereto is introduced into the heat treating furnace; or, wherein portions of sand core and/or sand mold that are not attached to a casting are introduced into the heat treating furnace. Wherein, the reclaiming within the furnace is carried out, in part, by a fluidizer that promotes binder combustion by one or more process of agitating, heating, and oxygenating. Wherein, the characteristics of the reclaimed sand are selectively controlled by controlling the dwell time of the sand within the heat treating furnace.

Abstract: An electro-explosive device has two serpentine resistors fabricated on a thermally conductive substrate with the resistors being interconnected by a central bridge element. The resistance of the bridge element is much lower than that of the serpentine resistors and the serpentine resistors have a much larger surface area to volume ratio. A layer of zirconium is placed on the bridge element and explodes into a plasma along with the bridge element in order to ignite a pyrotechnic compound. The resistance of the bridge element increases with temperature whereby the bridge element receives more of the energy from the applied signal as the temperature increases. The EED is insensitive to coupled RF energy and to an electrostatic discharge since most of the energy from these stray signals is directed to the serpentine resistors and not to the bridge element. In another embodiment, two of the resistors are metal-oxide phase variable resistances and a third resistor is formed from a bowtie-shaped layer of zirconium.

Abstract: A suction strainer includes a hollow internal core tube and an external filtering surface built around the internal core tube. A plurality of openings are defined through the side wall of the internal core tube core. In some cases the openings through the side wall are constructed and arranged such that there is somewhat less open area near the downstream end than the upstream end of the internal core tube, and the amount of open area tapers between the upstream end and the downstream end. As a result, when liquid is drawn into the internal core tube through the plurality of openings, a substantially uniform inflow distribution may be defined along substantially the entire length of the internal core tube. The internal core tube functions as a rigid structural support for the external filtering surface, enabling the apparatus to withstand post-LOCA hydrodynamic forces.

Abstract: A temporary silt guard for temporarily enclosing the open upper end of a drop inlet during the construction of a road system in commercial and residential developments is adapted to fit over and seat upon the open end of the drop inlet to enable storm runoff water to drain into the drop inlet while preventing silt and debris from being carried into and collected therein. The silt guard includes a body having a filter box portion formed from a series of radially spaced slats. A silt screen material is encircled about at least the slats of the filter box portion and secured to the body portion, with the slats providing rigidity and strength to the silt screen material. The silt screen material filters out silt and debris while enabling storm water and runoff to drain into the drop inlet.

Abstract: An artificial ember bed (5) for use within a fireplace (7) is disclosed. The fireplace will include a burner (12, 13) positioned below an elevated log grate (19), on which at least a pair of spaced artificial logs (20, 21) will be positioned. Situated in the space defined by, and between the logs will be an ember bed support grate (24), having an elevated surface on which a plurality of non-combustible artificial embers (25) will be disposed such that in use they will glow to create the visual appearance of glowing embers within the fire. The ember bed support grate may be constructed with a Z-shaped or a C-shaped geometry, or may include a pair of bifurcated legs (33, 34), or a pair of spaced legs (36, 37) for supporting the ember bed support grate on the log grate within the fireplace. In addition, the ember bed support grate can be fashioned as a planar grate, supported either on the logs, or received within notches (39) defined within opposed faces of the logs when situated atop the log grate.
