Abstract: A dual position step assembly that can be mounted into a standard square towing receiver that is previously installed on a pickup truck or similar vehicle is described. The step assembly is mounted to the rear of the vehicle. The step can be pivoted to two positions, either vertical or horizontal. When placed in the vertical position the step assembly automatically seats into a downward self locking position. The weight of the step assembly provides the force necessary to set the step assembly into the self locking position.

Abstract: The wire caddy is designed to hold single or multiple spools of electrical wire commonly used in the building trades. This device allows wire spools to be inserted onto a support shaft and retained onto the support shaft by insertion of a retaining pin through retaining pin holes in the end of the support shaft. Wire is guided off the spool through a guide hole in the support bracket. The diameter of the support shaft is smaller than the diameter of the wire spool end plate center holes. The center line of the support shaft is positioned higher than the center line of the wire spool end plate holes. This creates a gap between the bottom of the support shaft and the edge of the wire spool hole. Thereby the wire spool is resting on and supported by the friction plate, and not the support shaft. Upon applying an upward pulling force, the wire spool is lifted off the friction plate allowing for uncoiling of the wire.

Abstract: A multi position step assembly that can be mounted into a standard square hitch or towing receiver 1 that is previously installed on a car, pickup truck or other vehicle is described. The step assembly is mounted to the rear of the vehicle. The step can be pivoted to three preset horizontal positions and secured in those positions by means of a set pin that is spring tensioned to put a downward force on the set pin so as to engage the set pin into a predrilled hole in a positioning plate, thereby securing the step in position. To change step positions a pull ring is pulled to an up position which will raise and disengage the set pin from the predrilled hole in the positioning plate, thereby allowing the movement of the step to another position. A dual position step assembly that can be mounted into a standard square towing receiver that is previously installed on a pickup truck or similar vehicle is described. The step assembly is mounted to the rear of the vehicle.

Abstract: An elongated mirrored surface has a temperature gradient established thereacross. Condensation forms along the mirrored surface and the edge of the condensation next to the portion of the mirrored without condensation is where the dew point temperature exists. A scanning means is provided for locating this edge of the condensation. Temperature sensing means, located at the edge, measures the dew point temperature.

Abstract: The present gun silencer includes an internal cardioid-shaped cavity which utilizes the principles of wave mechanics to attenuate the sound of a gun firing without contacting the projectile. The shock wave from a firing is totally internally reflected thereby confining and attenuating the sound from a gun firing. The silencer cavity is shaped in a manner guiding and concentrating shock waves from a gun firing to an exit port at which sound-absorbing material is present.

Abstract: An apparatus for guiding and cushioning a plurality of articles deposited into a container positioned beneath it. It is comprised of a rigid framework of spaced, elongated members having guides positioned at intervals along the members. The guides are tapered upward and extend outward on either side of the elongated members to define passages through which the articles pass, which passages are bounded by members on two sides and by the extended guide portions on the other sides. Flexible fingers extending downwardly and toward the center of each passage have mounting portions fastened to the elongated members by the tapered guides; preferably two fingers extend into different passages from a common mounting portion. The tapered guides align each article with a passage where the flexible fingers cushion and precisely position the article as it moves into the container. Each mounting portion can be resiliently fastened in place to provide adjustability of the cushioning effect by adjusting the resiliency.

Abstract: A test chamber for simulating outdoor environmental conditions including the controlled formation of dew or frost on test objects in the chamber. Air processing equipment connected to the chamber includes two types of humidifying equipment, two types of de-humidifying apparatus, and a heating/cooling system using a secondary heating/cooling fluid which heats and/or cools the air without condensation. A radiative cooling system comprising a chilled black body absorbs heat from test objects to induce dew or frost formation. The equipment is controlled by a microprocessor.
