Abstract: The present disclosure provides a method of flushing a reactor used in the production of linear alpha olefins, including flushing reactor equipment with toluene from a solvent source, wherein the reactor contains by-products from the production of the linear alpha olefins, wherein the by-products include a polymeric material. The flushed toluene containing polymeric material is directed into a separation train containing the linear alpha olefins, wherein the polymeric material is soluble in at least one of the linear alpha olefins. The linear alpha olefins can be separated from the toluene and the toluene is recycled to the solvent source.

Abstract: Several of the films that comprise various energy producing or control devices, for example, electrochromic devices, lithium batteries, and photovoltaic cells, are sensitive to moisture in some way. They may be especially vulnerable to moisture at particular stages during their fabrication. It may also be highly desirable during fabrication to be able to wash particulates from the surface. The particulates may be generated some aspect of the fabrication process, or they may arise from the environment in which the fabrication takes place. This invention shows ways to remove said particles from the surface without incurring the damage associated with typical washing processes, resulting in higher manufacturing yields and better device performance.

Abstract: An apparatus and method for removing support material from a part formed by three-dimensional (3D) printing. The support removal machine contains a tank for submersion of a 3D printed part into a liquid mass. The liquid mass circulates in the tank in a controlled manner such that submerged parts remain centrally suspended in the tank, regardless of the material, density and geometry comprising the part. The part circulates and rotates in conjunction with the rotational flow of the liquid mass for uniform exposure to means of support removal. During rotation, the part may be subjected to multiple means of agitation that include heat, chemical and ultrasonic, in order to optimize energy use and maximize efficiency of the removal of support material.

Abstract: A filtration efficiency, which is similar to the filtration efficiency obtained when a plurality of filters are provided, can be obtained by one filter, and decrease in throughput can be prevented. Based on a control signal from a control unit 101, a resist liquid L is sucked into a pump 70 through a filter. A part of the resist liquid sucked in the pump is discharged from a discharge nozzle 7. The remaining resist liquid is returned to a supply conduit 51b on a primary side of the filter. A process is synthesized by adding a replenishment amount equal to the discharge amount to the return amount. The discharge of the synthesized process liquid and the filtration thereof by the filter are performed the number of times corresponding to a rate between the discharge amount and the return amount.

Abstract: An apparatus for raising and lowering a cutting tool within a decoking drum, a decoking system and a method of raising and lowering a decoking system cutting tool. Instead of using metallic ropes, chains, or a self-propelled gear-based approach, non-metallic belts are secured at respective ends to a crosshead and one or more counterweights to enable vertical movement of the crosshead that in turn permits vertical movement of the cutting tool throughout the height of the drum. A motorized pulley system controls the movement of the belt, and preferably avoids having the motor be carried by the crosshead. The belts on each pulley are preferably arranged as cooperative sets so that within each set, both primary load belts and secondary load belts are present.

Applicants have also identified a specific metering tip/nozzle, dispense rate, and low pressure application of not more than 100 psi are critical to achieving the benefits of the invention.

Abstract: A method of removing food soils from a recirculated washing solution includes adding a flocculating agent to the recirculated washing solution and separating the particulates from the recirculated washing solution using a hydrocyclone. The flocculating agent causes a portion of the food soils to combine into particulates having a higher density.

Abstract: The present invention discloses a method for self-cleaning filters without having to open the filter housing. Wash nozzles are integrated with the filter housings such that when the filters are clogged, both back-wash and regular washing can be performed with practically no down time. Moreover, without opening the filter housing, the hazardous components of the fluid to be filtered can be contained and dealt with before they escape the filter housing, thereby significantly reduces the environmental impact and harm to the working crew.
