  • Patent number: 5411165
    Abstract: A system providing rapid and efficient evacuation of valuables from a storage site such a home or office. Such rapid evacuation is often required in the face of impending disaster. A storage container, for example a drawer, is provided with an inner lining. Valuables are stored on the lining within the drawer. The lining itself is an open carrier having side walls which are folded so as to configure the liner to the drawer. In the case of emergency evacuation, the side walls of the liner are rapidly unfolded by grasping draw strings which act to remove the liner from the drawer and to close the liner to provide a closed transport carrier for the valuables stored within the drawer.

  • Patent number: 5358298
    Abstract: A flexible enclosure structure which may be placed on a vehicle so that its bottom and two sides are anchored within the vehicle's interior. The top panel is fastened to the roof, preferably in a manner which results in a low air flow impedance. With the internal anchoring and the low air flow impedance to the structure along the outer surfaces of the vehicle, the vehicle may be driven on roadways for short errands while the structure is in place. When desired, the enclosure structure may be removed from the vehicle and folded, because of its flexibility, into a small, conveniently carried package. The structure includes windows to permit the entry of light and entry and exit flaps which may be closed during inclement weather. When the flaps are open, screening inhibits the entry of insects. When camping of more than a transient moment is anticipated, a tent enclosure may be coupled to the vehicle mounted enclosure.

  • Patent number: 5345826
    Abstract: A static load tester is shown that provides tensile testing of plated test specimens to detect hydrogen embrittlement damage from plating processes. The functional components of the device are centrally aligned within a channel of an I-beam frame. A load cell and electronic readout provide the user with a measure of the tensile force applied to up to eight test specimens mounted end to end in a tester. Tension is applied to the specimens through use of a simple threaded rod and nut load application system at the base of the device. A static load tester may be incorporated into each channel of the I-beam frame, thereby providing a double testing unit. Additionally, a series of I-beam frame tester configurations may be incorporated into one multiple testing unit. Each multiple testing unit has a number of static load testers equal to double the number of I-beam frames mounted into the unit.

  • Patent number: 5313868
    Abstract: A service platform for transport within an area wherein an explosive device is present. A remotely controlled tractor provides the primary motive force for moving the service platform through the explosion-prone area. Because of the danger personnel might experience in entering such an area, the tractor is remotely controlled by a transmitter manned by a person at a remote location. In situations where the explosive device comprises one or more mines hidden in the earth, the mobile support of the tractor will distribute the weight of the tractor over a sufficiently large ground surface area such that mines embedded in the ground will not have their firing circuitry triggered by passage of the tractor above the mine. However, the service platform is equipped with rugged, massive, ground contacting elements which are sufficiently light so as to not trigger the firing mechanism of anti-tank mines, but sufficiently massive to cause the firing of anti-personnel mines.

  • Patent number: 5295537
    Abstract: A sand separator is used in a well from which particulate bearing liquids are extracted into tubing for transport up the tubing. The separator causes the fluid bearing particulate matter to be accelerated. This acceleration in turn causes the particulate matter to separate from the fluid because of the higher mass and greater inertia of the particulate matter. The fluid, after separation of the particulate matter, is drawn up through the pump. The particulates preferably accumulate within a sand trap which can be pulled from the well and emptied as desired. In the case wherein the particulate matter tends to float within the liquid part of the mixture, a strainer is added after the initial inertia separation of particles from the liquid. The strainer prevents the passage of particulate matter which would tend otherwise to float upward into the output port by which the liquid passes up the tube.

  • Patent number: 5288003
    Abstract: A car-top-transportable baggage carrier is particularly suited for use on aerodynamically streamlined cars which have no rain gutters. The carrier is made from a single continuous piece of material so that no seams or joinings in the material are produced in the face of the enclosure or the top and bottom surfaces. Weight distribution paneling within a load bearing floor pad inserted at the bottom of the carrier serve to distribute the weight of articles emplaced within the carrier, yet permit the carrier to be accordion folded for storage when not in use. Straps affixed to the top of the carrier are employed to secure the carrier in position on top of an automobile. The straps are equipped with innovative door head liner hooks which secure the carrier to the interior of the automobile adjacent the top of the car door. Releasable couplings permit rapid removal and replacement of the distal ends of the strapping as desired.

  • Patent number: 5284261
    Abstract: An insert for a nursing bottle is disclosed. It is placed between the bottle and the nipple. The insert has a channel that communicates with the air passage holes in the nipple. The channel itself has air passage holes that are sized to allow air into the bottle but prevent the liquid in the bottle from exiting. This arrangement prevents the creation of a vacumn in the bottle when the liquid exits through the nipple.

  • Patent number: 5272956
    Abstract: In an automatic weapon system such as the AR-15/M-16, the passage of propellant gas-carried heat, powder residues, and dirt to the bolt carrier and the upper receiver of the weapon is eliminated. The standard recoil spring housed in the buttstock of the weapon can be eliminated to produce a weapon with a folding stock or a machine pistol. Propelling gasses drive a piston which in turn drives a piston rod which is integrally coupled with the carrier key of the weapon. There is no relative movement between the rod and the carrier key. Therefore, no impact is delivered by the rod to the carrier. Longer carrier life is assured. The original recoil spring can be eliminated by a recoil spring on the piston rod. The ability to vary the volume of the gas chamber in which the piston is driven permits control of the firing rate of the weapon. A further enhancement permits the total blockage of propellant gasses from the gas cylinder so that the weapon may only be fired in a single action, single shot mode.

  • Patent number: 5237724
    Abstract: A hinge pin swing stop which is coupled to the hinge pin of a door hinge or other hinged object and acts to limit the rotating swing of that object about the hinge. The swing stop can include a section which acts as the replacement hinge pin, a first extension which bears upon the solidly backed structure of a door or other object, and an angular extension which is brought into interfering contact with a structurally solid support to which the hinged object is attached. The point at which swing stopping interferences are encountered is selectedly adjustable.

  • Patent number: 5231971
    Abstract: A bow tuning tool has two coupling mechanisms. The first of these coupling mechanisms makes coupling contact with the archer's bow. The second makes coupling contact with an arrow shaft. By coupling the arrow shaft to the tool and bringing the tool into coupling contact with the bow, tuning adjustments to the blow are facilitated. A three-in-one bow tuning tool is derived: a Bow Square and Nock Set, used to set the height of an adjustable arrow rest and to locate nock points; a Bow Center set for setting the flight path of the arrow shaft past the bow; and, a Bow Tiller Gauge to equalize the setting of the tiller height above and below the point on the bow at which the bow is gripped.
