Abstract: A shielding device provides an area of protection to mechanics during initial unbolting of flanged pipe connections, to block and redirect any unexpected discharge of product away from the mechanic to the opposite side of the flange. This device has an elongated body wrapped around a pipe flange positioned in the gap area between the flanges. The body is made from an elastic material such as rubber or plastic, or a pliable material such as rubber, plastic or teflon, and is secured to the flange by fasteners on each end of the device. The device provides an area of protection greater than half the circumference of the flange, by having the elongated body securely seated in the gap of the flange over this area. The remaining area of the flange gap remains unobstructed to discharge product leaks.

Abstract: An extruded plastic structure for edging a plant (tree, shrub or other planting) in a lawn. The strip has a border section, which slopes upward slightly to attach to a vertical ridge, usually in the form of an inverted rectangular section. A porous foam center permits watering of the root structure of the tree The edging is constructed as two symmetrical half circular sections which may be snapped together around the tree.

Abstract: A suitable casting alloy for use in a fluid treatment device may be made as a copper-nickel-zinc-tin (CU--NI--ZN--SN) alloy without the addition of silver, silicon or magnesium, if certain identified trace metals are kept below certain levels. It appears that the previously identified additive metals, which are either expensive or dangerous, act to counteract the deleterious effects of these trace contaminants, and are not necessary of the contaminants are controlled. A method of forming the alloy prevents the explosive reactions encountered when melting together metals having significantly differing vaporization and melting temperatures.

Abstract: A system for diverting refrigerant into an auxiliary receiving vessel to reduce refrigerator system pressure during an incipient over-pressure condition to prevent activation of safety pressure relief valves and release of refrigerant into the atmosphere.

Abstract: A threaded fitting, having an external thread and sealing surfaces to match standard tubing fitting designs. The fitting has an internal bore which is defined by two coaxially aligned cavities; an upper cavity is the diameter to receive a standard diameter tubing end, and has a bottom end defined by a metal web which extends into the bore of the fitting a distance. This web forms a stop upon which a tubing end can be bottomed. A counter groove is cut into the fitting adjacent to the upper cavity for receiving the tubing end. In use, a brazing metal ring is inserted into the upper counter groove, and a tubing end is inserted into the first cavity, and bottomed against the web. The fitting and tubing end are then clamped or held and a tapered mandrel, of a diameter equal to the inner diameter of the tubing, is inserted upward into the second cavity; this mandrel deforms the web upward into the interior of the tubing end, forming a positive mechanical seal and lock between the tubing and fitting.

Abstract: A rubber modified asphalt for use as a paving compound is formed by reacting very fine ground particulate rubber with paving grade asphalt and mixing the combination at between 300 and 400 degrees F. The resulting mixture reacts fully within 25 minutes or less to form a freely pouring mixture; the reacted mixture can be held at normal asphalt working temperatures for at least 96 hours without degradation.

The combination is coupled to a mobile, powered elevating work platform, to provide cargo items to a work crew at a controlled rate and at a proper height for safest handling, over the range of motions and elevations of the work platform.

Abstract: A compact, easily stowed removable drain line for a Recreational Vehicle holding tank provides a rigid straight line flow path to prevent puddling or trapping of waste flows between Recreational Vehicle holding tank and sewage dump station. The invention also provides for minimal force transfer into the holding tank structure and the drain valve, minimizing the possibility of accidental damage or rupture of these sensitive components. In particular, no exposed components exist during movement of the Recreational Vehicle, minimizing the risk of breaching of sewage during over road movement, and the invention particularly protects against damage from accidental movement of the vehicle while attached to the sewage dump station.

Abstract: An integral, one piece tubular product with a threaded end for mating with threaded connectors is produced by preforming a series of compression and expansion operations on the end of a tubing blank to provide a sufficiently thick wall structure for the formation of rolled threads, and to directly form an external hex head surface for the application of wrenching forces.

Abstract: An apparatus for purifying waste water in an indoor environment is a container for holding the waste water to be treated together with at least one liner for receiving and holding an individual removable pot in which grows a house plant in a planting medium, typically expanded clay particles. The design of the container sets a constant interior water level. The support for the pots and the design of the pots then established the depth into this water level to which the growing medium and root structure of the chosen purification plants is immersed. INterlocking lips between the pot and the apparatus seal against the escape of odor producing gasses. The apparatus thus permits a wide variety of chosen house or office plants to be used for biological water purification, providing optimum growth conditions for any chosen plant.

Abstract: A system for diverting refrigerant into an auxiliary receiving vessel to reduce refrigerator system pressure during an incipient over-pressure condition to prevent activation of safety pressure relief valves and release of refrigerant into the atmosphere.

Abstract: A portable, foldable camp or field seat, which may be folded to a size which can fit into a standard rear pocket. A base plate, having a footprint resistant to sinking in loose soil has, pivotally affixed, spaced apart wire frame seat supports which rise at an outward angle to support a cloth seat. The cloth seat is attached around the upper ends of the two foldable wire frame supports, forming the front and rear of the seat. The seat is used like a small saddle, sitting in a fore and aft direction. The weight of the body upon the cloth seat pulls the seat tight against the frame supports and forces the frame supports apart, pivotally around the base plate. This provides uniform support pressure for the seated individual without significant binding, pressure or discomfort from the frame supports. The base plate prevents sinking of the seat into the soil and provides for a low, squat position, particularly useful for hunters and the like.

Abstract: A connecting rod crankshaft bearing, provided for installation in the connecting rod at the crankshaft end, eliminates the necessity for reaming out the ridge in a cylinder during rebuilding. The rod bearing is an eccentric bearing, provided as two semi-circular sections having a slightly greater thickness along the lower section than on the upper section so as to offset the center of the inner surface from the outer surface of the bearing.This offset restricts the uptravel of the connecting rod. This in turn lowers the position of the piston during reciprocating travel by the same amount, eliminating possible impact with wear ridges within the cylinder. The cylinder thus need not be reamed to remove these ridges, as they no longer present a source of damaging impact during piston travel.

Abstract: A Rosser type debarker head has a plurality of rounded, indexable cutting teeth spaced in patterns of repeated rows running axially the length of the cylindrical surface, each tooth being spaced along the cylindrical surface so that the total cutting pattern produced by a single rotation of the head creates a uniform round toothed scalloped effect. Each tooth is shadowed by adjacent offset teeth so that only the portion of the round tooth outside of a cord representing essentially one-sixth of the circumference of the tooth is exposed to direct cutting impact. The remainder of the round tooth is shadowed by adjacent cutter teeth. As a result, the debarker head produces a uniform scalloped cut, producing a shallow, smooth cut upon the log with limited splintering, while reducing the impact on the teeth so that tooth life is significantly extended.

Abstract: Disclosed are safety debris collectors for collecting dust and debris, such as concrete particles and dust, rock chips, steel particles, radioactive particles, insulation and other particles and dust when drilling, chipping and using stud guns, drills, piston drive devices and other operating tools used in the construction industry which create working dust or debris and the like. The safety debris catcher does not rotate or move with the operating portion of the tool, it is easily and readily connected to and detached from an operating tool or device, it can be used in confined spaces, such as spaces between beams, braces, and ceilings at different elevations, and it can be used at any angle and effectively collect debris, dust and other particles. A rotating inner disk within the base of the debris catcher forms a rotating inner surface of a chip chamber, urging debris away form the tool into a debris receiving chamber.

Abstract: A process for creating a foot support, and the support created thereby. The foot support transfers the force of walking uniformly over the surface of the foot from the points of metatarsal contact through the arch to the heel. A mold prepared to match the foot in relaxed configuration is used to cast a positive impression representing the relaxed surface of the bottom of the foot. The positive impression is leveled horizontally by a level across the high points, or contact points on the bottom of the foot. A casting is made, matching this horizontal level; when cured the casting forms the insert of the invention.

Abstract: A multi-stage active biological waste water treatment Apparatus. An anaerobic, sludge settling first lagoon or chamber has a distributed piping system providing multiple, spaced outlets for the inflow of waste water; the multiple outlets distribute the buildup of sludge within the anaerobic chamber, which otherwise tends to block influent pipe outlets, by shifting flow from one outlet pipe to the next as sludge builds up.A controlled flow aspirator system then injects air into the odoriferous effluent from the anaerobic chamber as part of the natural water flow out of the anaerobic chamber into the first of a series of biological treatment chambers, without exposing the effluent to local surroundings.Within an aerobic duckweed treatment chamber, a rotating effluent outflow pipe retains an effective biomass of duckweed for the treatment process, yet, as desired, removes a chosen quantity of this growing biomass for harvesting.

Abstract: A ventilator has automatic controls with a particular control sequence to progressively wean the patient from mechanical ventilation, but that detects and maintains the patient's condition against the patient's inability to resume normal respiration. The ventilator non-invasively monitors body oxygen saturation level to insure adequate respiration, with minimum excess oxygen exposure, and monitors exhaled tidal carbon dioxide levels to control mechanically assisted respiration rate.

Abstract: The rear horizontal gate or tailgate of a truck is locked in a vertical or horizontal position by a pivoting horizontal bar. Fingers extend fixedly outward from the rear of the bed of a truck. The bar hinges are slit so that in the horizontal position they swing down over and grasp the fingers, holding the tailgate in a locked downward position. The tailgate is placed into an upward position by swinging the bar outward, freeing it from the fingers and raising the gate vertically. The weight of the horizontal bar swings down and the bar latches against the upper surface of the support fingers, holding the tailgate in a locked upward position. The tailgate thus can be locked in one of the two positions, up or down, while the truck is in motion without requiring the use of lock pins, simply by manipulation of the weighted horizontal bar and hinge member.

Abstract: A pontoon float has a flexible collapsible structure which may be extended by interlinking pontoon float platforms to form an elongated platform as for a dock or pier. Each pontoon float platform is supported by a rectilinear array of removable, stackable hollow floats, removably fastened to permanently affixed lid sections, forming an air tight seal. The individual floats are secured to the platform only by removable upper ends, and are otherwise free. The floats may be readily removed and stacked, reducing each pontoon platform to a planar section and a stacked, compact array of float members. The pontoon sections are reinforced by a grid of stringers, providing adequate rigidity without undue stiffness. Preferably, each pontoon sections is provided with interlocking extension plates on an end and a side and a mating pattern of interlocking holes on a second end and side so that they can be adjoined to form complex large floating structures as required.
