Abstract: A trigger mechanism for a semiautomatic firearm whereby a spring loaded hammer strut acting through a lever system puts a light pressure to hold a sear in a locked position and whereby recoil after firing causes the sear to return to a locked position before release of firing pressure on a trigger through action of the lever system and a trigger reset system; a trigger pull spring acting to return said trigger reset system to firing position after pressure is released on the trigger.

Abstract: An auxiliary sprinkler system control unit that interrupts a sprinkler system when ambient temperature is below thirty six degrees and when wind velocity is above ten miles per hour and when one half inch of water has been measured and delays the sprinkler for one day when in each month a daily running total of water addition is greater than a daily running total of an expected evapotranspiration or soil evaporation and plant transpiration rate as published for a specific area; said unit thereby providing a minimum amount of water to keep a healthy but slow growing turf.

Abstract: A modular system using molten aluminum alloy for degradation of wastes to innocuous molecular products using a central molten alloy heat source unit and separate reactor units for differing wastes. The molten alloy is pumped to the reactor units and returns by gravity flow to the central heat source which is maintained at about 850 to 950 degrees centigrade.

Abstract: A jet bath designed to use minimum water, to use a formed in place low cost waterfall type water inlet, to have pulsating and massaging air-water jets appropriately located in the tub, to allow user adjustment of water temperature, to prevent heating the water above 122 degrees Fahrenheit and prevent tripping of a manually resettable high temperature limit switch with initial filling of the tub with overheated water.

Abstract: A user fittable and user mountable blind for an arched window comprising a minimum of two rigid slat hangers with angled slots to hold trimmable slats as long as the widest part of the window in the hangers and adjustable hinges with one short side to connect to the hangers and a slotted longer side to allow fastening to a top part of the window frame with a single mounting screw or to allow fastening to a mounting block slidably held in a track mounted in a top part of the window frame. After moving the adjustable hinges using the mounting block or utilizing the slot in the hinge to bring the slats to a horizontal position the user may trim the slats to exactly fit the window frame.

Abstract: An excavator with a wireless controlled hopper-spreader allows a single operator to strip off topsoil and spread the stripped off soil more or less evenly after a mineable substance such as gravel is removed. The hopper-spreader uses about a fifty foot conveyor and may be totally operated by an operator in the excavator cab. This combination may be both faster and cheaper than a normal dragline operation.

Abstract: A method for making caps of eight different sizes for each of a persons teeth allows premaking caps that will fit almost any tooth of any patient; caps are preferably prepared from a commercially available quartz or silicon dioxide filled acrylic material called Artglass r; the caps allow curing a material such as Charisma r with ultraviolet light thereby allowing a practitioner to place a cap containing Charisma r over a tooth prepared for capping; settle the cap in place; remove any excess and expose the capped tooth with a ultraviolet light for about three minutes to form a solidly capped tooth in one visit to the practitioners office.

Abstract: This invention comprises a cam driven plug that opens and closes exhaust valve ports in an engine cylinder and while it moves to open forms an optimum variable geometry nozzle for the exhaust gasses exiting from the cylinder to impart maximum velocity energy to these exhaust gasses for delivery first at supersonic speed and then lower velocities as the cylinder pressure decays to drive a turbine that delivers power to the shaft of the internal combustion engine or other service loads.

Abstract: A kit or cohesive group of reusable elements to aid a facilitator or trainer to enhance interchange and organization of group discussions comprising portable foldable backboards, plastic erasable, reusable recording sheets, at least one process display wallboard, multiple colored or imprinted cards of variable shapes and sizes that will allow recording thereon and removably cling to said sheets and said wallboard and necessary marking and erasing accessories. With a preferred embodiment further including a specially designed carrying cases for ease of transport of said components.

Abstract: A compact no moving part refrigeration unit powered with a flame driven generator is contained along with a propane cylinder and necessary controls in a cylindrical upright unit with an expanded base; the unit is sized to make four to eight pounds of ice in about a four hour period.

Abstract: A scuba diver mouthpiece that is held in place between users' molars and bicuspids using flexible partially fluid filled retention arm segments with an offset in the mouthpiece and pressure equalizing channel between retention arm segments to allow comfortable use of the mouthpiece for prolonged periods of time. The disclosure further describes a variable sized breathing air humidifier and removable adapter for use with the mouthpiece.

Abstract: An auxiliary urinal retrofittable to an existing commode. The urinal is connected to a base plate which is placed between the base of the toilet and the floor and allows the urinal to drain liquid into the drain used by the commode. The urinal has a cup shaped head with a flush ring therein and a free standing semi-rigid drain line connected thereto and to the base plate to effect drainage. The semi-rigid drain line has limited travel segments to allow the user to manually position the urinal head to an optimum use position. In an alternative embodiment, the urinal is housed in a cover and placed against a wall.

Abstract: An enhanced daytime and nighttime visibility marker for electrical lines is disclosed in two embodiments. Both embodiments are shaped to give visibility from all angles and to allow smooth covering with retroreflective tape. One embodiment includes a continuous burning interior light for maximum nighttime visibility.

Abstract: A machine designed to automatically and economically remove spaced earthen plugs, fracture the soil around holes formed by the plug removal, fill the holes with earthen material and tamp and crimp the grass to provide a revitalized golf green that rapidly returns to a playable surface.

Abstract: The invention encompasses a torus formed by heated and cooled junctions of dissimilar metals such as copper and nickel to generate a low voltage current and form an electrical path of greatly enhanced conductivity wherein a greater current flow may be induced to form a stronger magnetic field. Current at higher voltage may be incrementally removed by magnetic field arrangements to act as magnetic variable switches while at the same time the magnetic field is contained and current also flows through the torus.

Abstract: The invention encompasses a process and equipment for an aggressive approach to remediation of specific hydrocarbon contaminated soil and groundwater using horizontal sparging pipes in or below the contamination with a matrix of vertical pipes that act to conduct sparger gas with associated hydrocarbons to the surface for hydrocarbon removal before recycle and also to collect and strip hydrocarbons washed horizontally into the collector pipes by injection of a washing fluid through a matrix of vertical wash pipes spaced between the collector pipes.

Abstract: The present invention discloses several new calcium indicator dyes which are retained in the cytosol or which bind to cellular membranes and report calcium levels near the membrane. These indicators are analogs of a previously described tetracarboxylate calcium indicator fura-2 and indo-1 where the 5' methyl of the BAPTA moiety is replaced with a derivative of propionic acid in the form of --CH.sub.2 CH.sub.2 CON--(CH2).sub.n --N(X.sub.1)X.sub.2, where n is 4. The propionic acid derivative provides a flexible means for introducing additional functionality to the calcium indicator without greatly impacting the fluorescence and ion chelating properties of the parental indicator. When X.sub.1 is CH.sub.2 COOH and X.sub.2 is part of a ring system like piperazine, a fluorescent calcium indicator, Fura-PE3, is obtained which resists compartmentalization and leakage out of the cytosol.
