Abstract:
A portable delivery system for delivering a multiple part coating composition for in situ coating an internal pipeline surface comprises a housing including a controller, at least two composition containers, a first hose, a hose delivery system, a pump, and at least two mass flow meters. The composition containers contain differing compositions, and each container includes a composition depth monitoring apparatus. The first hose comprises at least two additional hoses, where two of the additional hoses each deliver one of the compositions to a composition applicator. The hose delivery system stores and delivers the first hose to the pipeline, and the pump is coupled to the composition containers and the first hose. The mass flow meters are each coupled to a pump outlet corresponding to an outlet of the respective first or second composition container.
Abstract:
A coating device for coating an inside of a hollow body with an atomized fluid has at least one atomizing tube enclosing an atomizing channel. A pressurized propellant gas for atomizing an unatomized fluid can be introduced into the atomizing tube. The atomizing tube has at least one outlet opening and further has at least one hollow needle having a discharge opening for the unatomized fluid. The at least one hollow needle interacts with the atomizing channel and is arranged essentially coaxially thereto. The atomizing tube and the hollow needle form a Venturi arrangement.
Abstract:
This is a photoconductor and dispenser assembly and system. The photoconductor is in a tubular form so as to accept a tubular formed dispenser within its hollow portion. The dispenser will coat within this hollow portion a uniform coating of an acoustical dampening material. This material will dull any sound produced by the photoconductive marking system. The assembly is the tube having in its hollow portion this dispenser. The dispenser fits tightly but movably within the hollow portion.
Abstract:
Disclosed is an apparatus and method for forming lubricant recesses having minute configurations by applying a photolithograph method in a curved inner surface, such as a cylinder bore surface of a cylinder block, the inside of a cylinder liner, the inside of a compressor cylinder, a big end of a connecting rod, a big end bearing, a shaft insertion hole of a rocker arm, or the like in an internal combustion engine.
Abstract:
A wheel lubricating device for lubricating at least a portion of a wheel, including: a lubrication applicator, a rotary drive mechanism at least indirectly coupled to said lubrication applicator, a lubrication supply conduit in fluid communication with said lubrication applicator, a transfer pump for transferring a lubricating medium through said lubrication supply conduit to said lubrication applicator.
Abstract:
Methods for coating medical devices for implantation within a body vessel are provided comprising providing a cylindrical container, placing a medical device inside the cylindrical container, and applying a polymer in liquid form inside the container.
Abstract:
A planetary gear retrieval system for pulling a sled at a constant velocity along an interior of a pipe, and a sled for applying a coating material to the interior of the large-diameter pipe. The planetary gear retrieval system is connected to the sled via a chain, and has a network of gears controlled by a first variable speed microcontroller. A spinner on a linear oscillating plate provided on the sled is controlled by a second variable speed microcontroller. The first and second microcontrollers are programmable to be synchronized with one another so as to pull the sled at a desired constant rate and achieve a desired number of passes of the spinner along a given length of pipe while the sled is pulled at the desired rate.
Abstract:
The present invention relates to coating of tubes, and more particularly to a system and method for coating and/or renovating deteriorated or pitted tubes to extend tube life and enhance performance. Using this system and method a thin coating is applied to the interior of a tube such that the coating is uniform in thickness and covers all regions of the tube. The coating material may be selected to minimize changes in heat transfer or may be selected to provide for the change in working fluid within the tube such that the working fluid does not negatively interact with the tube material.
Abstract:
There is provided a method of lining the internal surface of a pipe involving a larger diameter portion, said method comprising the steps of inserting a first pig into the pipe from an open end thereof, said first pig being a spherical body made of a resilient material having a diameter larger than the pipe inner diameter and having a number of grooves formed on the surface thereof for permitting air escape, injecting behind the first pig a necessary amount of resin into the pipe, inserting behind the resin a second pig into the pipe, said second pig having a diameter smaller than the pipe inner diameter such that a resin lining layer having a desired thickness may be formed on the internal surface of the pipe, providing a positive pressure and applying the positive pressure behind the second pig in the pipe, and causing the first pig, the resin and the second pig to move through the pipe along the entire length thereof by the positive pressure, so as to form a resin lining layer on the internal surface of the pipe by means of the second pig.
Abstract:
A method and apparatus for quickly and inexpensively providing a constant extrusion pressure for pipeline lining with a mortar. A mandrel is inserted in a pipeline section with a slug of mortar ahead thereof. A pushing force is applied thereto to overcome resistance to movement thereof. A constant tension pull is applied to the mandrel to effect relatively constant but effective extrusion pressure between the mandrel and the pipeline wall for extrusion of mortar on the inner wall of the pipeline section.
