Abstract: A specialized vehicle for movement along a path parallel to a plurality of containers for dispensing molten asphalt from the vehicle into the containers. The vehicle is configured to physically locate the operator and the controls at the rear corner of the vehicle so that the operator can readily oversee and control movement of the vehicle and the asphalt dispensing operations.

Abstract: Apparatus for periodically draining, flushing and replacing the operational water supply in an evaporative cooler during operation thereof and for completely draining the cooler when its operation is terminated. The apparatus includes a special siphon drain valve mounted in the sump of the cooler so as to be normally in an unprimed non-siphoning state and when in such a state, the evaporative cooler will operate in the normal manner. When the cooler is in normal operation, its water supply will increase in mineral salt concentration and other contaminants, such as dirt, bacteria and the like.

Abstract: An apparatus for efficiently and economically cooling air by sequentially passing the air to be cooled through a chilled water heat exchanger mechanism and then through an evaporative cooler mechanism.

Abstract: A hand-held liquid herbicide applicator for wipingly applying the liquid herbicide on undesired vegetation. The applicator includes an elongated tubular handle having a supply container on its upper end with a special differential pressure operated vent valve in the container. A flow control valve is mounted in the handle for controlling the flow of the liquid herbicide through the handle to an applicator head carried on the bottom of the handle. The applicator head includes an especially configured synthetic sponge which is formed with a porous relatively dense peripheral skin so that the liquid herbicide received from the handle will evenly saturate the entire sponge to prevent uncontrollable liquid flow in one or more localized parts of the sponge.

Abstract: A method for making an irregularly configured endless metal frame and fixedly attaching a sheet of flexible material thereto.

Abstract: An air conducting mechanism for receiving evaporatively cooled air from a source thereof and delivering the evaporatively cooled air to the air inlet face of the condenser coil of a remotely located refrigeration unit.

Abstract: A sonic pressure wave surface operated pump for use in pumping liquid from low production wells. The pump includes an aboveground generator which produces sonic pressure waves of special character in a liquid column. The sonic pressure waves are transmitted by the liquid column through a normally closed liquid discharge unit to a subterranean pumping assembly which is operated by the waves to draw the liquid into the pumping assembly and build the hydrostatic pressure thereof to a point where the liquid discharge unit will move to its open position which allows the sonic pressure waves which are reflected by the subterranean pumping assembly to carry the liquid to the surface.

Abstract: A liquid cooled connector for mounting and electrically connecting an integrated circuit package on one side of a backpanel, said connector including a thrust/heat dissipating member for placement on the integrated circuit package, a thrust inducing mounting plate for positioning on the opposite side of the backpanel, and complemental elements of a demountable biasing connection passing through the backpanel so as to interconnect the thrust inducing mounting plate and the thrust/heat dissipating member to cause an interaction therebetween which pressurizes the integrated circuit package into conductive contact with the backpanel.

Abstract: The present invention discloses a method for containerizing asphalt in a plurality of manually handleable packages.

Abstract: Apparatus for periodically draining, flushing and replacing the water supply in an evaporative cooler during operation thereof and for completely draining the cooler when its operation is terminated. The apparatus includes a siphon drain valve mounted in the sump of the cooler and configured for movement between siphoning and non-siphoning positions with the movement being controlled by a solenoid. When the cooler is in normal operation, the solenoid is deenergized which places the siphon drain valve in the non-siphoning position and when in such normal operation, the water supply will increase in mineral salt concentration and other cooler damaging contaminants. At periodic intervals, such as under control of a time clock, the apparatus is switched to its draining, flushing and water replacing operation mode. This is accomplished by energizing the solenoid to initiate the siphoning action of the siphon drain valve to drain the water from the cooler.

Abstract: A solar energy collector and utilization system of the type having a movably mounted collector for reflectively concentrating solar radiation into a focal point that impinges on an energy absorber device is provided with a solar tracking subsystem which includes heat sensor devices that detect movement of the radiation focal point away from the absorber as a result of the diurnal cycle of the sun and upon sensing such movement will enable controlled movements of the collector to be made so that the radiation focal point will be moved back onto the absorber.

Abstract: A plurality of especially configured cementitious blocks arranged in a modular array with at least one planar polyurethane foam panel cast and cured in situ within the blocks to fusingly bond the blocks together and provide the modular array with an integral coextensive uninterrupted thermally insulative barrier.

Abstract: A method and apparatus for mixing molten asphalt and granulated rubber including an asphalt input system and a rubber input system for delivering the molten asphalt and the granulated rubber in accordance with predetermined mixture proportions to a two-stage mixing system which mixes those materials to form a consistantly formululated thoroughly blended asphalt-rubber composition.

Abstract: A large capacity drainage receptacle for flush mounting in a surface to be drained including an especially configured mounting flange from which a receptacle body integrally depends. The drainage receptacle is formed of light weight thin-wall stainless steel and is configured to demountably support a strainer basket therein for catching and retaining solid foreign materials and for demountably supporting a flush mounted perforated cover plate thereon for supporting traffic passing over the drainage receptacle.

Abstract: A drive system having a power input subsystem which operates and regulates the input power to the drive system in response to the demand placed thereon, and apportions the input power in accordance with the individual loads placed on the drive system by separate driven entities.

Abstract: A container for receiving molten asphalt for subsequent use at a job site includes a cardboard having a bag-shaped liner therein for receiving and containing the molten asphalt. The bag-shaped liner has special properties which are conducive to an efficient asphalt containerization process and are compatible with the requirements for handling and preparing the asphalt for use at the job site.

Abstract: An apparatus for efficiently and economically cooling air by sequentially passing the air to be cooled through a chilled water heat exchanger mechanism and then through an evaporative cooler mechanism.

Abstract: An apparatus for evaporatively cooling air including an air moving mechanism for supplying air under pressure to an evaporator duct wherein water is sprayed into the airstream countercurrent to the airflow direction. The evaporator duct is especially configured to inhibit moisture migration toward the air moving device and the sprayed water is precooled to increase operating efficiency. A second stage of evaporative cooling may be included by tandemly coupling a second stage evaporator duct to the outlet of the first stage evaporator duct.

Abstract: An apparatus for selective application of liquid herbicide includes a tubular handle which serves as a reservoir for containing the herbicide and for supplying the herbicide to an integral applicator head. The reservoir handle has a valve for controlling the herbicide dispensing flow rate of the applicator head which includes at least one elongated wicking element by which the herbicide is wipingly applied on undesired vegetation.
