Abstract: An umbrella assembly providing a dihedral shelter atop a pole which can be deployed to different dihedral angles and retracted to a compact configuration. It further includes a vent port in a cavity which is overhung by a positively positioned vent port cover.
Abstract: A method to make an in-situ piling in which a dry binder and water are injected into the situs of an intended piling. A rotary tool is inserted into the soil which as it descends into the situs and exits it, mixes the soil, binder and soil along with the air used to inject the binder, reducing the size of binder particles and rendering the resulting mixture sufficiently fluid that much of the air can percolate from it. The water is supplied in such amount as to reduce the unit strength of the ultimate cured piling, but sufficiently strong and reliably consistent in its physical properties.
Abstract: An instant water heater utilizing positive temperature coefficient plastic electrically conductive material structures for electrodes. The heating of the water is not generated by the electrodes, but instead by the resistance of the water to the electrical current flowing between them. The material of the electrodes undergoes a phase change at certain temperatures when whereby it converts from electrically conductive to electrically non-conductive at a predetermined temperature. The output temperature of the water is determined by a combination of the area of the electrodes that confront one another, the water's conductivity, the flow rate of the water and the current limiting capability of the conductive electrode materials positive temperature coefficient, which reduces or stops the heating of the water when the intended water temperature is achieved.
Abstract: An attachment for a fishing rod to respond to tension on the fishing line. In one mode it responds to a lateral pull on the rod tip. In another mode it responds to an axial pull on the line. It enables accurate adjustment of the drag, and can indicate when the tension on the line is in a safe or risky range relative to the rated stress of the line.
Abstract: A rockable and stackable chaise lounge. It includes a pair of frame members each formed by a downwardly convex rocker and an upwardly convex rail joined at front and rear ends. The frames are joined at their front and rear ends by spreaders. Adjustable stops are provided to limit the extent of rocking. A seat with a reclining back is supported between the frame by the rails.
Abstract: A single degree of freedom positioner resistant to axial and rotational motion on two axes, and to rotation around a third axis, but permitting axial movement along the third axis. The axes are orthogonally related. The positioner is characterized by support of a stage by a plurality of stiffly flexible end supported shear webs that bend in a rolling motion to enable the said axial motion.
Abstract: A pivoted gate across an opening from a gutter into a collector basin. An actuator inside the basin is insensitive to slow flow rates, but includes a rotor with vanes that actuate an opening linkage at sufficiently high rates of flow. A float is included in the actuator to exert a gate-opening torque when the rotor is flooded.

Abstract: Method and apparatus to produce in-situ pilings, controllably injecting binder and water into soil formation in which the piling is to be formed, the quantities of water and binder being respective to strength demands for the piling, and to demand for water to supplement existing water to react (hydrate) with the binder.
Abstract: A tie down resistive to strong winds for lightweight but bulky equipment. The tie down includes anchors driven into the ground which hold cables that in turn are attached to the base of the equipment.
Abstract: An opener to assist in the opening of a threaded lid from a threaded jar. The opener is a body at least partially to embrace the peripheral wall of a lid. Preferably it allows for an expansion to facilitate application, and a shoulder to be abutted by a thumb or finger to add torque to the removal efforts.
Abstract: A hollow, open-ended closure for the tank valve which enables a large cross-section area of discharge port to be used, and which can pass bowl-refill water during the flushing sequence. It is especially useful as part of a valve in which it can be tilted to open the tank valve with reduced physical effort.
Abstract: A holder for flexible abrasive sheets. An abrasive sheet is gripped by a gripper actuated by a rotationally mounted cam pin that reciprocates a cam plate which pulls an edge of the sheet tightly against a backing surface so it can respond to oscillation of a sander to which the holder is mounted.
Abstract: An omni-directional wind turbine electric generation system including a wind rotor carrying wind responsive vanes which on one surface exert an aerodynamic lifting force and on the other a blocking force both of which exert a torque in the same rotational sense, and an electric generator directly connected to said wind rotor and coaxial therewith, without transmission means between them.
Abstract: A vortex type gas lamp comprising a base and an axially extending-transparent shield. Gas is supplied near the bottom end of the shield. The shield is formed of a plurality (preferably two) axial curved sections which overlap one another at their axial edges to form tangentially directed port. Combustion of the gas with atmospheric oxygen admitted through the ports results in an axial vortex of burning gas useful for illumination, decoration and heat.
Abstract: A method of forming in-situ pilings in clay soil. An auger stirrer is rotatably and axially forced into the ground. Water, dry binder (cement/or lime), and air are injected to lubricate the tool, and liquify the mix of clay soil, binder and air to form a uniform structure, most of the air percolating from the mix before it hardens.
Abstract: In the subsurface irrigation of crops, using injectors to provide micro-bubbles of useful gases of improvement of delivery of a more uniform stream with lesser variation in gas content and lesser tendency of particulate fines to settle out, thereby reducing the need to flush the system with attendant waste of water.
Abstract: A signal to warn of the open condition of a sub-grade vault whose lid may be open or missing. A spring-loaded placard is held down in the vault by a closed lid and raises above the opening by its own stored energy when the lid is open or missing.
