Abstract: An improved vehicle jack and jack stand is provided, used separately or in combination, where the both the vehicle jack and jack stand are adapted to receive and support a cup means that also supports a block. The block is able to be interchanged with other blocks to accommodate virtually any type of vehicle. A single jack is able to be used with multiple jack stands, since each jack stand is able to provide support at the identical location as the jack does. This is extremely useful on vehicles with uni-body construction. The jack stand defines an adjustable head, where the head is able to fit between side members of the jack stand, so that both the jack and jack stand are able to be concurrently positioned beneath the cup and block means. The jack stand also provides a removable cross support, which allows the jack stand to be moved in or out of position while the jack is being used to elevate an automobile. The support is replaced prior to the time that the vehicle is lowered onto the jack stand.

Abstract: A temporary replacement allows a sheet of material to be affixed in place of the glass portion of a vehicle door window. The sheet of material may also be held in place using magnetic strips, that effectively fasten the material to the metal portion of the vehicle door. The material used may be transparent, translucent, or a mesh design, that allows the free flow of air. The temporary replacement window may have a single sheet configuration, or have a bag like configuration. The single sheet configuration is placed on the outer or external side of the vehicle window, with the sheet wrapping around the window frame. An elastic strap, defined around the sheet's peripheral edge restricts the diameter of its opening to a measurement less than the window frame. A bottom elastic strip may be used to hold the bottom of the sheet against the bottom of the window frame. Another configuration uses a bag, having a mouth that is able to allow the insertion of the vehicle window frame.

Abstract: A cavity is provided on the leading edge of an object that is subject to the flow of liquids or gasses, where said cavity preferably has a wall that follows the curvature of a diminishing sine wave, although other configurations are possible that do not follow a specific sine wave. The cavity accepts the flow of liquids or gasses that enter into the cavity, and where the dimensions of the cavity cause the flow of liquids or gases within it to form a pressure node that extends forward of the cavity. The pressure node provides a wedge means to cause oncoming gasses or liquids to divert around the object body ahead of the object body itself, decreasing turbulence around the periphery of the object. The cavity may be spherical, in the instance of a missile, plane, or underwater transportation means, or may be linear, in the instance of an automobile grill that is subject to wind, or a bridge support, where the bridge support has to maintain position against the flow of current.

Abstract: An improved welding apparatus, for use with a MIG apparatus, or a tungsten rod in a TIG apparatus. A nozzle housing, having an outer shroud, defines an airspace, which receives an injection of water vapor mist. The water vapor mist, when directed into the airspace in the nozzle housing, contacts the heated nozzle housing surface, and is then able to absorb the heat energy from the nozzle housing surface. When the water vapor mist absorbs heat energy, it undergoes a phase change from atomized water into steam. The steam is allowed to exit out of the rear portion of the rear of the nozzle assembly. The phase change of water to steam provides a significant heat transfer, due to the latent heat energy absorption capability of the water that is required to convert it from a liquid state to a gaseous state. This cooling apparatus, and method of cooling, both utilize a minimal amount of water usage, and also dramatically extends the usable life of the welding apparatus.

Abstract: A multi-point mobility device that is capable of navigating over rough terrain without difficulty, including snow, say and, and mud, and which is able to reconfigure the two belt track assemblies so as to minimize lateral friction by the belts with indoor floor surfaces or carpets. A separate rear wheel, located behind the side mounted track assemblies is able to be lowered when desired, so as to raise the rear portion of the multi-point mobility device off of the ground surface.

Abstract: An improved reusable writing tablet, having raised document guides that define a document support surface, and a method for affixing and removing a cover sheet over the document support surface, where said document guides define a means to allow the insertion of tabs defined by a cover sheet, so that a cover sheet is held securely in place, and is easily removable from the base to allow the placement of documents between said cover sheet and the document support surface, and where said documents are viewed through the cover sheet, and are prevented from sideways movement by the cover sheet and raised document guides.

Abstract: An apparatus having the capability to be used as a pump, or as a turbine, or as an engine with an ignition and fuel system, in which four rotors are arranged within a housing to define an inner and outer volume area, with a valve set comprised of rotating members that define various apertures, and which provide venting ports during their rotation about the inner or outer volume areas, where said venting ports vary in their opening size in relation to the rate of volume increase or decrease in the area they are venting. This apparatus is balanced and allows for high speed operation, with the rotating ports arranged during the rotation cycle so that when valve sets are on both ends of the rotors, opposable venting of the inner or outer volume area occurs on the bottom of the apparatus, in the same variable manner as the top valve set.

Abstract: An apparatus that directs the flow of heated air that is being discharged from a clothing dryer, in which the dryer is positioned upon a rigid support, that elevates the dryer above the normal ground surface. The dryer discharge hose is connected at one end to the dryer, and to a valve assembly, located beneath the dryer, housed in the dryer support. The valve may be actuated so that heated air is either directed to flow through the valve assembly, into another hose which vents directly outside, or through an interior discharge opening, so that heated air is reintroduced back into the dwelling. The apparatus is provided with an access door, so that the valve can be positioned as desired. If air is being reintroduced back into the dwelling, a removable air filtration system is provided. In the event that the air filtration system becomes overwhelmed with particulate matter, the valve has a safety flap which is actuated by increased air pressure, and allows the heated air to vent outside.

Abstract: An improved changeable visual display lamp, having the ability to accept single piece cylinder sheets of artwork, or other items for display, where the cylinder is able to be inserted into the confines of an annular tubing through the removal of a single piece of the lamp. The two variations of this lamp allow cylindrical items to either be inserted through the bottom of the lamp by the removal of a single plate, or through the top of the lamp, through the removal of a single ring, where the ring covers a circular gap that extends around a centrally located socket. No tools are necessary to change the item or items being displayed, the person changing the display is not exposed to electrical shock, and the time required to change the display is reduced to a nimum. Benefits of the ring are seen where the ring may be removed, and single piece cylinder artwork is removed or inserted, without even unplugging or disassembling the lamp, other than manipulation of the single ring.

Abstract: An improved tungsten insert gas welder, having a means to remove heat energy using pressurized air, and a method for removing the heat away from the welder head area. A source of pressurized air is delivered though a hose to the welder head, and is directed through heat conductive air tubes within the welder head, is forced through a plurality of coils which surround an area that contains heat energy created during the welding process. As the air moves through the coils, it acquires some of the heat energy within the welder head. The heated air is vented into an outer jacket, which contains the electrically conductive cables, and an airspace surrounding the cables. As the heated air moves toward a rear connector block, it contacts the length of the cables, and is able to transfer some of the heat to the cables.

Abstract: An orthopedic appliance that is designed to assist in the reduction of an anterior dislocation, during a course of treatment given to a person who is laying horizontal on a table or similar elevated surface, with the affected arm hanging directly downward. The appliance eliminates the need for a person to grip or in any way consciously hold on to weighted objects, thereby allowing the patient to fully relax during the treatment procedure. The appliance comprises one or more forearm straps which are wrapped around the forearm of the person receiving treatment, where one or more weighted units are attached to the forearm straps, with extending supports so that the weights hang down, so that a direct downward pull on the affected arm is possible. Said weighted units may be attached to the forearm straps using one or more descending loops, in which weights such as dumbbells may be placed.

Abstract: An improved laryngoscope blade, where the lingual side of the blade, being the side that is presented against a patient's tongue during examination, defines a concave area which defines a cavity which allows the patient's tongue to be cradled during the examination, and where the curved descending sides of the blade proiaote and urge the tongue into the cavity area, and prevent the tongue from flattening out sufficiently so as to curve over onto the top side of the blade, where the view of the patient's airway would be obstructed.

Abstract: A valve device that is incorporated into the cap used on plastic bottles, which allow the bottles to receive the injection of gaseous pressure so that the walls of the plastic bottles become firm and rigid, which maximizes the bottles floatation potential. This allow the bottles to be handled and stored easily. These bottles have uses for many types of floatation needs, such as buoys, rafts, etc. The bottles are particularly useful as floatation devices in the sport of fishing, with the addition of fishing lines and hooks.

Abstract: A rod gripping device, having a support member with a locking pin hole and a rod receiving hole, where the bores of each hole are situated perpendicular to each other, but parallel to a given plane that bisects the support, and where the bores of the holes intersect to form a common area shared by both bores. When a rod is inserted into the rod receiving bore, so that the rod occupies the common area shared by the bores, a set of angled wedges are situated on either side of the rod, with the wedges being located in the locking pin hole bore. A first wedge has a smooth bore through it, with the second wedge having a threaded bore. A locking pin is inserted through the first smooth bore wedge, which can slide along the shaft of the locking pin to the locking pin handle edge, with the second threaded bore wedge receiving the locking pin's threaded shaft portion.

Abstract: A rotary impeller pump that moves fluid using a rotary impeller, where at least one transtator, having one or more ports, is positioned within a groove on a front plate that is adjacent to the impeller, and where the transtator is movable within its groove. The port is positioned radially in relation to the impeller's axis of rotation, by moving the transtator, thus allowing fluid having specific pressures and flow rates at various points of radius of the impeller, to be directed to an exit port.

Abstract: An improved resealable bag, typically used for snacks such as potato chips, cookies, and other types of chips. A set of snaps are fixed directly onto the bag, and are spaced along each side of the bag, closer to the top than the bottom, with the space between a snap and the top of the bag sufficient so that the top edge and a portion of the bag can be folded over, and then the top portion of the bag being rolled in the opposite direction until the snaps are again oriented similarly as they were prior to the rolling. The snaps are grasped, which causes the sides of the bag adjacent to the snaps to move inward, providing an open space through which the snaps are urged together and attached to each other, so that the rolled portion is formed into a U-shape. This causes the folded top edge and layers of the rolled portion to press together, so as to prevent any air from moving from the outside of the bag to the contents, or from the contents to outside the bag.
