Abstract: A method and apparatus of circulating cavitation fluid within a cavitation fluid circulatory system is provided. The system provides a means of circulating the cavitation fluid through a cavitation chamber, before or during cavitation chamber operation, as well as a means of draining and filling the chamber with minimal, if any, exposure of the cavitation fluid to the outside environment. The apparatus includes a network of conduits coupling the cavitation chamber to a cavitation fluid reservoir and at least one external fluid pump. Preferably the cavitation fluid reservoir serves the dual function of fluid reservoir and degassing chamber. Manipulation of various valves within the conduit network allows the cavitation fluid to either be pumped from the reservoir into the cavitation chamber or from the cavitation chamber into the reservoir.

Abstract: A gel mixing system that employs a dynamic diffuser for quickly removing the air from the fluid as the fluid exits a traditional gel mixer and employs progressive dilution of the gel in a series of hydration tanks to maximize hydration time without allowing the gel to become so viscous that it is not easily diluted or pumped. High shear agitation of the fluid between the hydration tanks helps to increase the hydration rate. Progressive dilution of the gel increases residence time of the gel in the tanks and results in longer hydration time in the limited tank space available, resulting in continuous production of gel that is almost fully hydrated when it is pumped to the fracturing blender and subsequently to the well bore without the need for an increase in the volume of the hydration tanks.

Abstract: A batter mixing apparatus and process is disclosed for mixing a dry batter mix with a predetermined amount of water is adapted to continuously measure the temperature and the viscosity, in centipoises, with an inline viscometer. The controls of the apparatus are fully automated using a programmable logic controller in conjunction with a touchscreen display that provides real-time data, process control parameters, and a choice of batter recipes. Once the batter has reached a desired viscosity, a variable speed feed pump is used to pump the batter to a batter applicator where a food product is coated. Excess batter from the applicator is collected and returned to the mixing apparatus via a pump. The viscosity and temperature of the returned batter is measured and adjusted automatically with dry batter mix or water in order to satisfy the set parameters.

Abstract: An apparatus and a method for injecting a liquid dye into a polymer melt, which includes a metering pump with a metering inlet and a metering outlet. The metering inlet connects to a dye tank and the metering outlet connects to a polymer melt carrying component. To add the liquid dye to the polymer melt in the melt carrying component in a quantity that is as uniform and accurate as possible, the invention provides for connecting the metering inlet of the metering pump to a feed outlet of a feed pump, which connects with its feed inlet to the tank. With that, it is possible to generate a feed pressure at the metering inlet of the metering pump, which can be adapted to an injection pressure at the metering outlet of the metering pump.

Abstract: A method of manufacturing multi-layered, laminated, lipid-based sweet confections comprises tempering the lipid-based formulation for each layer, and depositing them separately onto a moving conveyor belt, which is passed through a cooling tunnel between the station where the first layer is placed on the conveyor belt and the station where the next layer is placed. If more than two layers are to be made, additional stations are employed further along the conveyor belt. A set of fingers is located at each station so as to striate the layers as they pass beneath the fingers, so as to govern the width of each ribbon that is thus formed. The width of the fingers in each successive set of fingers is not greater than the width of the fingers in the preceding set.

Abstract: A uniform small particle homogenizer for liquid product comprising a pair of intensifier cylinder pumps (20) driven by a hydraulic system (22). The pumps have a power stroke side and a suction stroke side, and a pair of proximity sensors (24) that interface with each pump to detect forward and rearward movement. A microprocessor (26) with timing capabilities controls the sequential operation of each pump with the power stroke of each pump timed to alternately produce a flow of the liquid product with a precisely timed flow overlap period from the alternating pumps. Since the power stroke takes a longer time than the suction stroke, the instant each power stroke is started the opposite pump is timed to hesitate and slightly overlap until a constant product flow-rate is produced from the alternating pumps, which eliminates large variances in pressure and therefore achieves uniformity in product particle size.

Abstract: A foam marking system is provided with separate tanks for water and foam concentrate. A water pump and a concentrate pump deliver water and concentrate from the respective tanks to a mixing chamber at a pre-selected ratio. The water pump is controlled by a master control, while the concentrate pump is controlled by a slave control depending from the master control. The master control generates and output signal which is sent to both the water pump and the slave control, such that the slave control and concentrate pump operate as a function of the master control and water pump, so that the selected mix ratio can be maintained, regardless of the output level of the foam from the system. A foam generation chamber connected to the mixing chamber and to an air source generates foam when the foam solution is mixed with air.

Abstract: A mechanical proportioner is provided with two pump lowers which are connected together by a yolk underneath an air-operated reciprocating piston pump. The pumps are staggered axially so as to enable overlapping of certain portions thereof thereby enabling the center-to-center distance to be minimized. The mix manifold is constructed in a concentric fashion such that mixed material does not come into contact with the mix manifold until it enters the static mixer at the exit of the manifold which is an easily disposable and replaceable part. The purge solvent valves on the mix manifold are each provided with an extension of their respective handles. If either purge valve is in its open position, a separate interlock handle operating the A and B side valves at the manifold inlet is prevented from opening. Similarly, if the interlock handle operating the A and B side valves is open, the purge valves cannot be opened.
