Abstract: An apparatus for preventing insects from entering a building through a doorway having an inner door separated by an air space from an outer door, which includes an aerosol can holder mounted on a vertical doorjamb between the doors; an aerosol can of insecticide having an upwardly extending spray nozzle positioned in the holder; a hinged, vertically movable lever projecting over the holder; a cam element mounted on the lever positioned and shaped to engage and depress the spray nozzle of the aerosol can; a first cable connected to the lever and extending through the inner door so as to be accessible inside the building and a second cable connected to the lever and extending through the outer door so as to be accessible outside the building; and, when either the first cable or the second cable is pulled, the lever will move downwardly to depress the nozzle and spray insecticide into the airspace between the doors to destroy any insects before the inner door is opened and the insects are able to enter the build

Abstract: An omni-directional yieldable joint for a vehicle exhaust stack includes an upper cylindrical member having a pair of elongated pivot sockets mounted on its lower end; a lower cylindrical member has a pair of elongated pivot rods mounted at its upper end for riding in the pivot sockets and making the upper and lower cylindrical members pivotable with respect to each other; a pair of springs attached between the upper and lower cylindrical members holds the two sections tightly together and, when the joint pivots due to the exhaust stack striking an overhead object, the stack will lean and the springs will stretch as much as necessary until the stack passes under and clears the obstruction, whereupon the springs will pull the upper and lower sections back into their normally vertical and axial alignment.

Abstract: This method for the trenchless, in situ repair of underground pipe includes the steps of isolating a section of pipe to be repaired, heating a sealing material (having predetermined physical and chemical properties) to a liquid state, pumping the liquid material, under pressure as required, into the isolated section of pipe; circulating the liquid through the isolated section of pipe; and forcing the liquid into and through cracks in the pipe and into the soil surrounding the pipe. This is a thermal process wherein the molten material which is forced into the cracks and soil, cools and solidifies. The remaining liquid circulates through the isolated section of pipe and stays in a liquid state, because of retained internal heat, until it is removed from the pipe for storage and reuse. With this process, a novel bottom plug is used which allows the sealant to be applied to all cracks, crevices and even openings found where the smaller pipe connects to the larger pipe.

Abstract: A hydrogen generating system produces hydrogen instantaneously upon contact of a catalyst and a reactant for simultaneous injection into the combustion chamber of an engine. The system includes an injector having an ignition chamber in communication with the combustion chamber. A catalyst is located in the ignition chamber. During the engine intake stroke, a reactant is fed into the ignition chamber where it reacts with the catalyst to produce hydrogen which is instantaneously drawn into the combustion chamber. A spark plug mounted on the injector provides a spark and the hydrogen in the ignition chamber and the combustion chamber explodes. The location of the catalyst in the injector provides for the generation of hydrogen and its immediate injection into the engine combustion chamber for use as a fuel. Automatic regeneration of the catalyst is provided by the fuel explosion, hydrogen and intense heat in the ignition chamber.

Abstract: A vehicle-mounted apparatus for excavating and transplanting trees includes a plurality of blade assemblies mounted on a multi-sided, horizontally disposed frame for overlying and substantially surrounding an excavation site. Each blade assembly includes a curved tower and a blade mounted on a slide assembly for reciprocation along the tower to effect penetration of the excavation site, and hydraulic power means for effecting reciprocation of the blade and slide. The slide assembly includes pliable, replaceable materials such as plastic and brass as the contact and sliding surfaces between the tower and the slide assembly. The tower is pivotable between a plurality of operational positions so as to be useful with a plurality of blades to remove sections of earth from the excavation area having different sizes, i.e., widths and depths, and having different shapes, e.g., a conical shape having parabolically curved sides or a truncated shape having parabolically curved sides.

Abstract: A combination vest-suspenders garment includes full front vest portions which meet in the front and button down the center, which taper at their upper ends to form relatively narrow shoulder portions and which flare outwardly in the traditional manner towards the waistline to a relatively wide waist area having side edges. Suspenders straps are connected to the shoulder portions and extend downwardly and rearwardly to approximately the middle of the back where they cross, and then extend further downwardly to ends at waist level where they have suspender snaps thereon for connection to trousers or skirts. A back band is made of a fabric gathered over a single elastic band which extends continuously across the back waist from the side edge of one front portion to the side edge of the other front portion.

Abstract: A hunting stand useful to provide an elevated hunting station for rifle and bow hunters has a basket shape and comprises a structure having a flat bottom member, a plurality of support members extending upwardly from the base to a top rail which encircles the space above the base member, and a seat supported by the upwardly extending members at a position between the base and top rim; spike means project from the rear of the base and top rim members for engaging the tree where the stand is mounted, and a pair of sleeves extend downwardly from the front of the base member for receiving the side pieces of a ladder extending from the ground to the stand. In a first embodiment of the invention, the several parts are welded together to form a rigid, permanently erected hunting stand; in a second embodiment of the invention, the several parts are rotatably and releasably connected to form a collapsible hunting stand capable of folding for easy storage and transport.

Abstract: Radiator plates are contoured to fit the rims of radiator tanks where the tanks are bolted to the radiator core, and the radiator plates have bolt holes therein which align with the bolt holes in the radiator tanks and the radiator core, whereby the radiator plates may be bolted along with the tanks to the radiator core to prevent deformation and failure of the tanks and leaking of the radiator.

Abstract: A conveyorized sorting and distribution system for the handling of packages of documents or other items includes an infeed conveyor in tandem with an inclined conveyor and a plurality of vertically adjustable conveyor divider plates positioned above the infeed and inclined conveyors to divide the conveying surfaces into a plurality of individual sorting lanes. The infeed and inclined conveyor belts have a plurality of longitudinal grooves therein which may be created by and are aligned with the divider plates which extend into said grooves. A conveyor end divider transition section positioned at the end of the inclined conveyor enables the conveyed materials to flow by means by gravity to a distribution transition section that includes a chute for each lane of conveyed materials. The distribution transition section provides for the optimum conveying angle for gravity flow of the conveyed materials and also provides the necessary direction changes to distribute the materials to the desired discharge chute.
