Abstract: An improved wood working facility has a table saw which is operated in combination with a table saw extension table. The extension table is provided with an array of orifices through which air is ejected to provide a buoyant support for boards and sheet material laid atop the extension table. An ordinary shop vacuum cleaner may be utilized as the source of air being expelled from the orifices. Air may also be received from a distribution system in the shop which distributes compressed air to the various machine sites. The air is provided to an air plenum below the extension table top and exits from the plenum via the multiplicity of orifices in the top of the table. A low surface frictional veneer on the table top adds to the effort reducing efficiency of the extension table.

Abstract: A urine collection vessel is coupled to the body of a person by means of a partial vacuum created within the collection vessel. An air flow valve at the output of the vessel is adjustable to control the degree of a partial vacuum created within the vessel as well as establishing control over the velocity of air flow through the valve and down the associated conduit through which urine is conducted to a reservoir in which the urine is accumulated. The device is intended for use primarily by people who are troubled with prostate or bladder problems which, without the use of the invention, would make it necessary for these persons to frequently fully rouse themselves from sleep and to exit from their beds in order to void their bladders in the course of the night.

Abstract: What has been disclosed are the means and method for erecting a structure of preformed, interlocking structural elements which may be assembled by unskilled workmen. The preformed structural elements are provided in selected color and texture and include insulative coating surfaces. The interlocking mating configurations of the preformed elements assure a structure whose elements are assembled plumb and true by virtue of their longitudinal axes intersecting orthogonally. The erection of offices, storage, and housing facilities is envisioned utilizing such preformed structural elements. The low cost of materials and the ability to erect structures utilizing the efforts of local, unskilled labor responds to existing immediate needs for housing and other building facilities.

Abstract: A ducted frieze vent which creates a duct-way for the free flow of air beneath the roof sheathing and between a pair of roof rafters and into the space beneath the building's roof. The frieze board employed has a sufficient thickness to accept a nail driven down through the roof sheathing as is required by many building codes. The duct-way is provided with a removable closure which is first positioned to prevent entry of airborne insulation into the duct-way. After insulation has been emplaced, the duct-way closure is removed by manual actuation of a rod by a person exterior of the building and of the insulated space.

Abstract: An improvement on a towing assembly of a 5th wheel trailer and a pick-up truck which has a 5th wheel hitch in its bed. The improvement is a tapered, streamlined, aerodynamic extension at the front of the 5th wheeler trailer. In addition to reducing the power required to tow the trailer, increasing the fuel efficiency of the towing assembly, greatly increasing the towed stability of the trailer; the improvement adds to the storage and sleeping space available to users of the trailer. Access to the extension is available through a separate exterior access door as well as through the original front window opening of the trailer. The improvement is useful for both retrofit and original equipment purposes.

Abstract: A smokeless, non-polluting barbecue cooker has a base canister with a centrally located firebox which communicates with a flue to conduct heat, produced from burning fuel within the firebox, upwards to an oven enclosure supported by the base canister. The heat enters the oven enclosure along its central axis. A grill for the support of food stuffs, to be cooked within the oven, prevents the placement of food stuffs directly over the firebox. Thus no drippings from the food can fall onto the hot fuel within the firebox to produce carcinogenic byproducts. A forced air blower provides sufficient oxygen to the firebox so that essentially complete combustion is achieved; and, the barbecue cooker is smokeless in its operation. Various methods for controlling the heat accumulated within the oven enclosure are disclosed.

Abstract: An improved pesticide application utilizes a relatively large replenishment tank to store several working days requirements of pesticide solution at a relatively high pressure head. Both solution and pressure head, portions thereof, are transferred to a portable, working cylinder from the replenishment tank. Because a pressure head is directly transferred from the replenishment tank to the portable cylinder, rather than creating a pressure head within the cylinder solely by the transfer of solution under pressure to the cylinder, the pressure head within the portable cylinder is maintained for a significant working period. The improved pesticide application system requires the handling of concentrated pesticides and water only once every several days, rather than 3 or 4 times a day. No manual hand pumping is required to maintain a pressure head within the portable cylinder.

Abstract: In a motor vehicle, for example a bus, sight and sound signals cause the motor vehicle driver to move the motor vehicle steering wheel to avoid a collision of the front or rear tire with the curb adjacent which the driver is parking the motor vehicle, or about which the motor vehicle is turning. The avoidance of such tire/curb collisions dramatically extends the working life of the front and rear tires, particularly the front tire, and generally obviates repeated body repairs caused by proximity induced damages resulting when tires are drawn too close to a curb.

Abstract: An arrow balancing tool is used in establishing the optimal balance point on an arrow to produce the most efficient flight characteristics in accord with manufacturer recommendations. Assuming that the optimal balance point will fall toward the nose end of the arrow, approximately 7 to 10% of the arrow length removed from the midpoint of the arrow, the invention provides a base with a scale graduated in units equivalent to 57% of the length of the arrows being balanced. A second scale is graduated in units representative of 60% of the lengths of the various arrows to be balanced. A reference point, zero on the various scales, is established at which the nock of the arrow is positioned. A fulcrum, slidingly coupled to the tool, is adjusted until the balance point of the arrow is determined. Indices on the sliding fulcrum are positioned for a readout on each of the scales. Actual scale values reflect current manufacturer recommendations for optimal balance of an arrow.

Abstract: An improved method for installing lawn sprinkler systems wherein a flexible interconnection line is inserted between the sprinkler head and the water supply line. The flexible interconnection line is preformed having a bend at each end thereof, the bends being orthogonal to each other and to the axis of the interconnection here. This arrangement of bends at the end of a flexible section permits the flexible section to be maintained in close parallel relationship to the water supply line to minimize the width of the trench which must be dug for emplacement of the water supply line beneath the surface of the ground. The preformed interconnection line is also provided with preformed threads at the end so that threaded coupling may be readily made to the water supply line as well as the sprinkler head. This arrangement of threaded coupling permits ready replacement of parts should damage ever occur in the line.

Abstract: A veterinary orthodontic fixture useful in correcting lingual displacement of the mandibular canine teeth of an animal. When the fixture is in place, inclined biting planes coupled to the maxillary cannies cause a buccal displacement of the mandibular cannies so as to move the mandibular cannies into their normal position where they will not traumatically interfere with the gingival tissue of the maxilla. A telescoping rod bridging the fixture from one canine tooth to the other provides a torque resistent element which prevents undue stress from being exerted on the maxillary canine onto which the fixture is attached. Because this rod is telescoping, no inhibiting restraints are placed on the normal growth development of the animal's jaw while the fixture is in place.

Abstract: An arched window opening may be shaded by rotating a shade through a segment of an arc. The slide rotator-arm hinging of the shade to permit its rotation from a position in which an accumulation of shading material is present beneath the hinge to one in which the shade material is distributed about a segment of an arc is disclosed.

Abstract: A flueless combustion system which accepts materials nominally designed as trash and waste, including the solid and gaseous combustion products of the system itself, and converts these materials and combustion products to marketable products. Pyrolytic conversion is employed to reform these materials and combustion products. The gaseous combustion products of this system are exhausted to an underwater distribution system which permits the gaseous combustion products to percolate through water which contains cellulosic materials to further absorb and entrap gases. The water, cellulosic materials, as well as sediments resulting from the cooling of the exhaust gases, are utilized within the pyrolytic process. The gases, steam, and heat resulting from the pyrolytic process are used in conversion processes such as the Fisher-Tropsche Process to provide marketable products. For example, the Fisher-Tropsche Process produces liquid fuels.

Abstract: A skate shoe to which a replacement runner may be rapidly, removably coupled. No manual manipulation of locking devices is required. A first end of the runner is pivotally coupled to the shoe's base via a slot and pin arrangement. The second end of the runner is then pivoted into snap-locking engagement with a locking mechanism in the base of the skate shoe. Finger pressure on the lock mechanism serves to unlatch the runner; and, a spring drives the runner outward from its engagement with the shoe base.

Abstract: A strap wrench made up of a semi-rigid, form retaining, planar strip wrap around. This wrap around is formed into a shape retaining loop, the opening of the loop being readily adjustable. Because of the semi-rigid, form retaining characteristics of the wrap around strip, the loop will retain its shape and size as it is moved about and positioned over an object to be rotated. A simple squeeze of the strip will conform the size of the loop to the outer diameter of the object to be rotated. A flexible pull cord is attached to the fore end of the semi-rigid, form retaining strip and wrapped about the strip prior to or as the strip is placed about the object to be rotated. A simple straight line pull on the flexible cord exerts a force which acts along a line which is tangent to the object to be rotated and which acts at a distance removed from the axis of that object.
