Abstract: A stream of process liquid is treated while flowing through in a horizontally elongated chamber having an open top. Longitudinally elongated electrode blades are aligned with the longitudinal dimension of the chamber. An overhead disbursement chamber supplies a sweeping air stream over the open top of the chamber for removing foam and gas reaction by-products. The electrode blades are separated and held at a desired spacing by small portable guides located below and above the blades.
Abstract: Inner (32) and outer (34) juxtaposed glazed panes are separated from each other by an interlayer containing a gas, and the gap between the panes is closed by a seal (48) near the perimeter of the panes. A thermally conductive, hermetically sealed receptacle (36) is positioned between the panes. The receptacle contains a phase change material (38) that reversibly absorbs, stores, and releases heat in response to temperature changes at least at one of the glazed panes.
Abstract: A catalytically active surface is provided on the clean, combustion-exposed parts of an internal combustion engine that is green, has low operating hours, or is of modern, low emission design. A substrate or thermal barrier coat of high surface area and preferably capable of maintaining a surface temperature of at least 450° C. is deposited in the combustion chamber. Zirconia, silica, or lube oil ash are suitable. A catalytically active moiety such as platinum or iron is dispersed in, on, or with the combustion facing surface of the substrate. Nanophase iron from ferrocene or nanophase platinum are suitable. Catalytic action is maintained by continuously providing a low level of catalytic precursor to the engine in the combustion charge.
Abstract: A container end is provided with a suitable stock thickness for necessary strength and pressure resistance over its selected areas of its central portion while employing a substantially thinner peripheral wall. A method of forming thins the peripheral wall by drawing and ironing in a single workstation using compound die that also shears the blank from sheet stock. Optionally, multi-layers or laminates form the central portion of a lid, with a reduced number of layers forming the peripheral wall. Alternatively, the peripheral wall is thinned by ironing, spinning, or roll forming after the blank is formed into a shell. A forming apparatus clamps a planar peripheral wall of a blank with a clamping element that includes a thining tool. The apparatus oppositely offsets the center of the blank from the peripheral wall to draw the peripheral wall over the thinning tool on the clamping element.
Abstract: A two piece housing for a spliced portion of multi-conductor copper core electric cable includes housings adapted for two, three, or four wire cable. A bottom mated structure (31) and a top mated structure (30) are predetermined to accept screws (15) for clamping the two structures together. The housing interior surface (28) includes mortised frusto-conical shaped openings (23) with grooves (26) at right angles and contiguous to the cable passage (24) for accepting and locking wire nuts (12) over wire splices (6). Opposing jaws (17),(18), and (19), adjacent to the point of cable entry/exit (25) inside the cable passage (24) engage a two, three, or four wire cable (20),(8),(22). The opposed jaw configuration includes a curved, wedge shaped inner lip (27); a wedge shaped flange (13); and a curved overlapping lip (14).
Abstract: Carpet masking film is reliably and removably applied to used carpet of unknown condition. In a pretreatment, the carpet is cleaned by physical separation of visible debris, followed by chemical or solvent cleaning of grease and soluble factors, restoring the carpet to a clean appearance. A primer layer is applied over the clean carpet fiber in quantity sufficient to establish a barrier and separation layer on top of the carpet fiber. Subsequently, a sprayed adhesive layer is applied over the primer layer. A carpet masking film is applied over the surface of the sprayed adhesive. The masking film may carry its own adhesive layer, which is applied to the sprayed adhesive to create a bonded sandwich structure that is removable as a unit with the masking film.
Abstract: A sensor detects force or other indications of an impending rollover of a motorized land vehicle. Upon detection of a threshold force value, the sensor actuates an applicator that delivers traction reducing fluid to the contact patch between at least one of the vehicle tires and the ground. The vehicle is enabled to dissipate the rollover inducing force by sliding laterally in preference to rolling over.
Abstract: A modular fence unit provides a rigid frame supporting flexible and resilient sheet plastic that is stretched over and secured to the frame to create a visually open, yet resilient barrier. Each modular unit is provided with a connector for joining together one or more juxtaposed modular units or for attachment to an available stationary fixture such as a wall. The connectors may permit junctions between units in freely selectable angled relationships. Connections may be hinged, while others may provide a releasable latch, allowing a modular unit to serve as an access gate.
Abstract: A three dimensional calendar display structure, generally resembling a ball, is formed and assembled from sheet stock. First and second regular hexagon facets provide stable bases at opposite ends of the structure, while first and second annular courses of isosceles pentagon facets, each lying along the perimeter of one of the hexagon facets, form an intermediate body of the display structure. The first and second courses are in opposed positions with the apex of each pentagon facet of one course in a position juxtaposed between apex edges of two different neighboring pentagon facets of the other course. Calendar indicia are displayed on the pentagon facets, enduring indicia are displayed on the hexagon facets, and portions of the figure 8 seam pattern and stitching of a baseball are displayed on selected facets such that the continuous figure 8 pattern is displayed on the assembled display structure.
Abstract: A propeller (10) including a hub (11), a plurality of blades (13) extending outwardly from the hub (11) and part annular connecting elements (17) which interconnect tips (16) of adjacent blades (13). The trailing edges (21) of the elements (17) extend from the trailing edge of one blade (13) at its tip to intersect the adjacent blade (13) at a relief point (23) on the high pressure side of the blade (13) between the leading and trailing edges of the blade (13). The leading edge (20) of the elements (17) extends from the leading edge of a blade (13) at its tip (16) to intersect the adjacent blade (13) at a relief point (25) on the low pressure side of the blade (13) intermediate the leading and trailing edges of the blade (13) at its tip (16).
Abstract: The curative action of drugs, including herbal remedies, allopathic remedies, and periodontal remedies, is enhanced and accelerated by administering such drugs in combination or association with probiotics, especially those of genus Lactococcus, Lactobacillus, Pediococcus, Streptococcus, Propionibacterium, Brevibacterium, Penicillium, and Saccharomyces.

Abstract: Paraxial rays and marginal rays entering the eye do not share a common point of focus in emmetropes, adults usually having a slightly positive spherical aberration. There is provided a method of treatment and prevention of myopia by inducing positive spherical aberration in the myopic eye. The cornea 30 of a myopic eye 31 is fitted with a lens 32 having its outer surface 34 formed having increasing dioptric power away from the axis 35 of the lens and cornea 30. Paraxial light rays 36 entering the central portion 37 of the lens 32 are focused on the retina 40 of the eye 31, producing a clear image of an object. Marginal light rays 41 entering the peripheral portion 42 of the cornea 30 are focused in a plane between the cornea 30 and the retina 40, and produce positive spherical aberration of the image on the latter. This positive spherical aberration produces a physiological effect on the eye which tends to inhibit growth of the eye, thus mitigating the tendency for the myopic eye to grow longer.

Abstract: A cable lock is incorporated into the grip of a ski pole, using the base of the grip as a lock housing. Each ski carries an engaging member that can be fastened into the lock housing to attach each pole to a ski, such as for theft prevention, storage or carrying. In addition, the cable lock wraps the poles and skis and can attach them to a fixed object. The lock housing covers the mounting of the engaging member to the ski, which prevents tampering while the skis and poles are locked.
Abstract: A conveyor belt cleaning device provides a belt scraper blade and a roller juxtaposed to the blade on its downstream side, relative to the direction of conveyor belt travel. Frictional contact between the moving conveyor belt and roller drives the roller. The scraper blade scrapes stringy materials from the belt and the roller pinches trailing stringy materials between the belt and the roller, pulling such materials from the blade.
Abstract: In a combined backpack and folding chair, the chair has a camp stool base frame. A pivoting backrest is held in upright position on the stool frame by in-turned, truncated ends at the bottom of a backrest frame, which strike the camp stool frame. Alternatively, the backrest frame has a continuous bar at its bottom, which strikes the camp stool frame. The backpack is offset from the chair by clearance established in the dimension of a bridge between the backpack and chair. The in-turned ends clear the backpack by a lateral distance, by-passing the sides of the backpack. The continuous bar clears the backpack by a longitudinal distance, by-passing the rear face of the backpack.
Abstract: A first media provides an oxygen inducer such as catalase, bound and stabilized in pellet form so as to dissipate slowly into aqueous surroundings. A second media provides an oxygen supplier such as a peroxide, stabilized by combination with a proteinaceous compound such as urea and bound in a matrix that limits oxygen release. The two media are combined in aqueous environment to generate nascent oxygen at a modulated rate such that the oxygen is efficiently absorbed into the surrounding aqueous environment, promoting growth of aerobic species and reducing biological pollution. Specific adaptations demonstrate benefits of use in shrimp or fish ponds, raw milk, fruit juice, fresh food, silage and animal feed, fertilizer, plumbing systems, and grease traps. When used in ponds, further adaptations reduce algae and phytoplankton populations.
