Abstract: A main wing positioning and release system particularly adapted for use with a toy or model aircraft, includes a wing positioning bracket upon the axial centerline of the aircraft, the bracket having projecting elements directed upwardly from the centerline of the aircraft. The system also includes a wing release mechanism including a lower portion press-fittably securable to the upwardly projecting elements of the positioning bracket to provide proper positioning of the release mechanism relative to the aircraft fuselage, a rear area of the lower portion including a press fittable receiving recess, an upper surface of the lower portion of the release mechanism proportioned for complemental engagement of a lower surface of the main wing.

Abstract: A series of die spacers of differing shades are used to match or replicate an assortment of tooth stump or dentin tooth shades. Such die spacers correspond to shades of various manufacturers. This allows the dentist to approximate the proper shade of the tooth preparation in his prescription of a translucent restoration which is communicated to the technician. The technician then applies onto the die of the tooth preparation a die spacer closely matching the chosen tooth stump shade, allowing the technician to wax-up over the die with the selected die spacer. The die spacer retains the traditional function of creating the necessary space under the wax pattern or wax-up. After removal of the wax-up from the die, it is processed, following the manufacturer's procedures, to make a non-opacious substructure of, for example, a translucent ceramic restoration.

Abstract: A fluid engine for use in pneumatically operated toys such as wheeled vehicles or airplanes includes an engine having a fluid input cavity which is in continuous fluid communication with a source of compressed air, a fluid delivery cavity which is in continuous communication with a piston cavity bounded by a moveable piston mounted in a cylinder member and which is separated from the fluid input cavity by a wall having a valve opening, and exhaust apertures which are separated from the fluid delivery cavity. A valve rod is movably housed to open the valve opening and close the exhaust apertures during the piston's power stroke, and to close the valve opening and open the exhaust opening during the piston's exhaust stroke. The valve rod is operatively connected to a piston to act in synchronism with it by the use of a cam integrally secured to a propeller power shaft.

Abstract: A modular soil conserving planter constitutes a longitudinal trough having open transverse end faces, the trough including a lower horizontal grate and an upper horizontal grate, each of such grates extending along substantially the longitudinal length of the trough, the lower grate defining a drainage grate and the upper grate defining a soil retention grate, a region of the trough beneath the drainage grate including apertures for control of drainage from the trough, in which longitudinal ends of the trough. Each longitudinal end of the trough further include means for selectable connections to open end faces of adjoining like planters.

Abstract: A showerhead system with internal filtration media includes a fluid-tight pressure housing having a fluid inlet and a fluid outlet, the outlet substantially co-axial with the inlet, the housing having a substantially cylindrical internal surface. The system further includes several porous radial disks axially disposed internally to the pressure housing and having circumferential edges in integral communication with the internal cylindrical surface of the pressure housing. The system also include filtration media positional within regions defined between the porous disks. The system additionally includes at least one rigid radial disk axially disposed within the axial distribution of the plurality of porous disks, the rigid disk including groups of apertures. The rigid disk may or may not have an integral securement to the internal cylindrical surface of the pressure housing such that its axial position, within the system, is defined by filtration media packed on either side of it.

Abstract: A modular soil conserving planter is definable in terms of a longitudinal trough having open transverse end faces and longitudinal side walls which are axially compressible, laterally flexible integral accordion-like surface, the surface including elements for control of drainage from the trough and each end face of the trough further including snap-fittable selectable connections to open end faces of adjoining like planters. In the bottommost region of the planter are provided drainage openings which control the rate at which water can escape from the planter through the effect of gravity and of osmosis from the surrounding soil.

Abstract: A buttress-thread dental implant constitutes a rigid body including axially symmetric and radially uniform circumferential spiral pitch surfaces in the range or about 22 to about 28 of such pitch surfaces per axial inch. Above each pitch surface is a concave upper bevel surface which is longer than a lower bevel surface beneath each pitch surface. The intersection of each plane of each pitch surface with each plane of each lower bevel surface defines a total included bevel angle in the range of about 90 to about 1.30 degrees. The implant is also characterized by ratio of thread pitch to thread depth in the range of about 1.25:1 to about 1.40:1.

Abstract: Bark, berries or tablets of the species Xanthoxylum clava-herculis L and Xanthoxylum americanum Hill, both of the yellow wood tree family, both containing the compound xanthoxylum, are employed for the treatment of varicose veins and other membrane and vascular disorders. Improved strength, flexibility, comfort, and blood flow of the veins, arteries and their constituent structures is obtained.

Abstract: The present invention especially for machine applications, also improves the invention air cleaning device, U.S. Pat. No. 4,585,599 dated Apr. 29, 1986. The present invention is the said air cleaning method U.S. Pat. No. 4,585.599 and which is in addition forming a multipurpose combinatory oil, air, gas, and pollution filtration system based on processing oil through purified water mixtures, includes water of hydration, in general, is based on the interaction of two liquid systems distinguished in nature and viscosity from each other. For example: oil as the solute which include polluted particles mixed within and purified water (H20) as the solvent and which are optionally charged electrostatically with opposite charges positive and negative. In addition, electro-magnetic separator is provided within for attracting magnetic particles from the oil into the water, for disposal.

Abstract: A multi-function chiropractic treatment table for effecting extension, flexion, lateral flexion and distraction of the spine of a patient. The table includes a weighted platform adapted to rest upon a floor, and telescoping vertical elevation units having upper and a lower ends, each upper end secured to a transverse horizontal pivot axis, the lower end integrally secured to the weighted platform. The table further includes a rigid elongate support frame having an upper part and a lower part, the support frame secured to the horizontal pivot axis of the elevation units, the upper part defining a plane tilted convexly relative to a plane defined by the lower part and an assembly means for selectably rotating the rigid support frame upon the transverse horizontal pivot axis.

Abstract: A multi-agent tri-daily comestible of vitamin, mineral, plant extracts, aminos, neurochemical precursors, enzymes, and Ph regulating agents which supply key elements necessary for proper metabolization and function of the human body delivered at specific times of the daily biocycle when the need for such specific agents exists in order to maximize the body's extra- and intra-cellular matrix to cellular and biochemical protective and repair mechanisms utilized to deter the effects of otherwise normal aging.
