Abstract: An apparatus for practicing golf putting strokes including a putting surface member for receiving a golf ball to be putted and a swing path defining member which extends angularly from the putting surface part and lies in a plane which defines a normal and desired putter swing path. The swing path defining part is laterally offset from the intended swing path of the putter to provide a person using the apparatus with a visual indication of a normal swing path to serve as a guide while making unfettered practice swings with the putter. The swing path defining member includes an unobstructed planar member and a flange which is mounted on the putting surface member and supports the unobstructed planar member at an angle of substantially 72.degree. with respect to the putting surface member.

Abstract: A sonic pressure wave operated pump is provided with a rotary sonic pressure wave generator which impactingly generates sonic pressure waves of special character in a column of liquid contained in the pump with the generated sonic pressure waves being transmitted through a metallic production tube about the inner walls of the tube to a pumping unit which is in communication with a liquid to be pumped. The pumping unit reflects the generated sonic pressure waves back into the center of the production tube for movement countercurrent to the movement of the generated sonic pressure waves with the pumping unit reacting to the reflection of the sonic pressure waves by intaking the liquid that is to be pumped so that it is carried through the production tube with the reflected sonic pressure waves.

Abstract: Underground irrigation apparatus (10) having a ground penetrating part (12) arranged for being inserted into ground to be irrigated with the assistance of a handle part (14) connected to the ground penetrating part. A fluid control assembly (16) associated with the ground penetrating part (12) and the handle part (14) provides a fluid flow under pressure to facilitate insertion into ground to be irrigated of the ground penetrating part (12) and subsequently a redirected flow to irrigate ground in which the ground penetrating part is inserted. The fluid control assembly (16) includes a valve (44) connectible to a suitable source of fluid for alternately directing same in a desired direction. A removable mixer portion (70) directs fluid along the path which irrigated ground in which the ground penetrating part (12) is inserted in order to add a fertilizer, and the like, to the irrigating flow.

Abstract: A liquid herbicide applicator mechanism mountable on a farming vehicle for wipingly applying the herbicide on undesired vegetation growing in a cultivated field. The applicator mechanism includes a tool bar for carrying a plurality of herbicide dispenser assemblies so that they alternately align with the rows of crop plants and the spaces therebetween as the vehicle moves through the cultivated field. Each of the herbicide dispenser assemblies receives the herbicide from a reservoir tank under the influence of gravity and has a herbicide wiper head which absorbs the herbicide for wiping application on the undesired vegetation. Each of the herbicide wiper heads is substantially rigid but deformably configurable so that it may be shaped into substantial conformity with the contour of the crop plant rows and the spaces in the cultivated field and each wiper head is provided with special absorbent wiper elements.

Abstract: A radial internal combustion engine having a rotor of the radially movable vane type eccentrically housed within a rotor chamber casing both of which are journalled for rotation within an engine housing. Combustion induced rotation of the rotor is coupled by a gear train to the rotor chamber casing for driving the rotor chamber casing at the same speed as the rotor. Impeller blades provided on the periphery of the rotor chamber casing are employed to supercharge the fuel mixture prior to its being directed into the volumetrically expandable and contractable combustion chambers provided about the periphery of the rotor.

Abstract: An apparatus for mixing an additive with molten paving material and for application of the resultant paving composition. The apparatus includes a mixing mechanism in heat transfer relationship with a heated materials tank for recirculatingly moving molten asphalt from the materials tank through the mixing mechanism and back to the materials tank with the additive being added and mixed with the recirculating molten paving material for production of the resulting paving composition which is subsequently supplied from the heated materials tank to an applicator device of the apparatus.

Abstract: A hand-held liquid herbicide applicator for wipingly applying the liquid herbicide on undesired vegetation. The applicator includes an elongated tubular handle for containing a supply of the liquid herbicide with a valve at the lower end of the handle to control the flow of herbicide from the handle to an applicator head carried on the bottom of the handle. The applicator head includes a demountable sponge of special configuration in that it has a porous relatively dense skin which causes even and complete saturation of the entire sponge to prevent uncontrollable liquid flow in one or more localized parts of the sponge.

Abstract: An impeller assembly for use in a blower structure including a blower wheel which defines a centrally located peripheral groove in which a special endless metallic pulley band is fixedly mounted and having a hub sleeve which is demountably carried on a tubular axle shaft which demountably carries a stub shaft in each of its opposite ends for rotatable journalling in the bearings of the blower structure.

Abstract: A device for demountable temporary locking of a door is configured for use in locking inwardly and outwardly opening doors from either or both the inside and the outside. The device includes a door engaging member having a collar plate removably mounted thereon for lockably mounting the door engaging member on the door, and having a slidably movable door jamb engaging member which is lockable in its door jamb engaging position.

Abstract: A fan-type evaporative cooler having an improved air handler assembly which locates the rotational path of the fan remotely from the air delivery outlet so that an open mesh grill may be safely used in the air delivery outlet opening, and the improved air handler includes a moisture extraction baffle which protects the internal and external workings of the fan drive motor from corrosion and mineral deposits.

Abstract: A variable volume single tube surface operated pump including a piston reciprocally mounted in a cylinder for alternately opening and closing a liquid delivery port formed in the sidewall of the cylinder and for generating a sonic pressure wave by impacting a column of liquid in a metallic tube extending from the cylinder to a remote pumping mechanism located in communication with the liquid to be pumped. The piston is especially configured with a central recess in the face thereof so that the sonic pressure waves generated thereby will pass through a sonic inductor and move downwardly toward the pumping mechanism in a spiral-like motion against the inner wall of the metallic tube and enter into a sonic intensifier chamber where they are reflected off the pumping mechanism into a central column which travels back toward the cylinder and causes the liquid to be pumped to move in that same direction.

Abstract: A manually manipulatable applicator mechanism for applying and embedding crushed rocks on selected areas of a paved surface. The mechanism includes a first gate structure by which an operator can vary the width dimension of the pattern of applied rocks and a second gate structure for controlling the quantity of rocks applied by the mechanism and thus controlling the thickness of the pattern of applied rocks.
