Abstract: An apparatus and method for cleaning the interior of an above ground storage tank includes a nozzle assembly mounted to a cover on the storage tank sidewall having a horizontally extending wash pipe fixedly and a suction pipe for recirculation of spent fluids. The wash pipe has an interior segment which can be extended to a tank floor and is configured with a bend to extend along the tank sidewall to which is attached a submersible swivel joint fitted with a choked nozzle. The nozzle assembly is attached to a control assembly so that the direction of flow from the nozzle may be manipulated by rotation of the swivel joint from the exterior of the storage tank. The nozzle also may be adjusted so the direction of flow may follow the angle of the tank floor.

Abstract: An oil skimmer and vacuum recovery apparatus providing a method for removing the contaminating oil floating on the surface of a water body is disclosed. The apparatus may be mounted on an oil recovery vessel and includes a vacuum head mounted to a vacuum system. The vacuum head is configured at a desired proximity above a horizontally disposed separation plate that is adjustably positionable to be placed between the water surface and a contaminating layer of floating oil. The vacuum system includes a vacuum pump and motor and an associated vacuum tank configured to a fluids collection chamber that is in communication with a fluids vacuum line attached to the vacuum head. A vacuum force is directed by the vacuum head to the layer of floating oil above the separation plate whereby and the oil layer is skimmed from over the separation plate and drawn through the vacuum head the fluids vacuum line to the fluids collection chamber where it is collected for disposal.

Abstract: A pipeline cleaning apparatus and method configured for use in cleaning and clearing a pipeline of transient fluids, hydrocarbons, and other unwanted debris is disclosed. The apparatus and method utilizes a vacuum assembly haying a collection tank connected to a pipeline by at temporary vacuum line. Negative pressure created by the vacuum assembly causes a compressible pig to move down the length of the pipeline and up the temporary vacuum line to push transient hydrocarbons, fluids, and other unwanted debris from within the pipeline to the collection tank. The removal of hydrocarbons and non-hydrocarbons from the pipeline cleans the pipeline and allows the pipeline to be abandoned while complying with federal regulations.

Abstract: A vacuum assisted drill cuttings dryer and handling apparatus has a vacuum tank and an associated vacuum pump and motor configured for use with a high speed centrifugal dryer. Cuttings are drawn from the shaker of a drilling rig into the centrifugal dryer by means of a vacuum created in the centrifugal dryer by the vacuum tank and an associated vacuum pump and motor. The dryer is provided with sealable exit doors that may be opened and closed in sequence to allow removal of the cuttings even as cuttings are drawn in to the centrifugal dryer. A fluids collection chamber in communication with vacuum lines between the vacuum tank and centrifugal dryer collects fluids drawn from the centrifugal dryer.

Abstract: A cable protector and access ramp apparatus and system are disclosed. The apparatus and system is comprised of a plurality of variously configured cable protector sections. Each of the sections has a protected raceway through which various piping, electrical, gas, communication and other service lines may be directed and front and rear ramps to allow vehicles to roll up and over the protected raceway. The raceway in each of the sections of the apparatus and system has a hinged cover which may be lifted to allow placement and access to the service lines. The front and rear ramps of each of the sections may be provided with a pivoting ramp cover having a slot configured to allow access to lifting channels in the frame. The lifting channels are configured to receive the tines of a forklift.

Abstract: The invention relates to an apparatus for dispensing a restricted amount of powdered material, comprising a repository (2) for powdered material (4), an outlet (12), and a conduit (3). The apparatus defines an airway arranged to enable air to be drawn through the resting powdered material in the repository, thereby entraining the powdered material in the airflow and drawing the air and entrained powdered material through the conduit. The air and entrained powdered material is thereafter expelled out of the outlet. Additionally, the invention relates to a dip tube (3) for use in apparatus for dispensing a powdered material.

Abstract: A drill cuttings handling system apparatus for use on an oil and gas drilling rig located on a drilling platform where the platform has drilling equipment that includes a system for circulating drilling mud through the borehole created by the drilling equipment that includes a drill cuttings shaker for removing drill cuttings from the circulating drilling mud and a drill cuttings collection trough. The drill cuttings handling system is comprised of a cyclone cuttings hopper, a vacuum pump, an engine and a solids pump. Conduit is attached to the cyclone cuttings hopper for delivering by vacuum flow a quantity of drill cuttings from the drill cuttings collection trough of the drilling mud system of the drilling rig to the cyclone cuttings hopper. Discharge conduit is connected to the solids pump to dispense drill cuttings from the solids pump to a desired location such as a cuttings box.

Abstract: A skin-contacting lubricating layer formed from a hydrogel polymer bonded to a rubber article (such as a surgeon's glove) is treated by means of surfactant material (such as a bactericidal cationic surfactant which preferably has a 6-18C alkyl or alkenyl group, such as an N-hexadecyl group) or a long chain fatty amine so as to substantially improve the lubricity of the layer with respect to damp skin.The hydrogel polymer is preferably a copolymer of 2-hydroxyethylmethacrylate (HEMA) with methacrylic acid (MAA) or with 2-ethylhexyl acrylate (EHA) or with both MAA and EHA. Such a hydrogel polymer has improved lubricity to dry skin and, if used for this purpose, need not be treated with a surfactant or fatty amine to improve the lubricity with respect to damp skin.
