The acidic cleaning composition includes a concentrated acidic solution, a strong oxidizer, a surfactant, a suitable solvent and/or sufficient quantities of water. The acidic cleaning composition rapidly removes soils from food and beverage contact surfaces such as, for example, brewing vats and kegs, without requiring CO2 be removed from the brewery vessel. The acidic cleaning composition can be in a concentrated form for dilution with additional dilution water at ambient or faucet temperature as opposed to requiring the use of “hot” water. The acidic cleaning composition is free-rinsing leaving essentially no residue on the contact surface. The surfactant provides low-foam properties so as to avoid cavitation and damage within a pump assembly.

  • Patent number: 9738918
    Abstract: A rapid one-pass liquid filtration system efficiently concentrates biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. Additional concentration stages may be added in “cascade” fashion, in order to concentrate particles below the size cut of each preceding stage remaining in the separated fluid in a concentrated sample suspension. This process can also be used to create a “band-pass” concentration for concentration of a particular target size particle within a narrow range.

  • Patent number: 9421557
    Abstract: A nozzle for discharging first and second fluids in a spray pattern into a vessel, such as oil and steam in a catalytic cracking unit, includes various configurations for preventing erosion of the outlet portion of the nozzle that otherwise might be due, for example, to contact with a catalyst or other predetermined substance. In one such nozzle, the exterior surface of the outlet portion substantially conforms to the internal contour of the vessel. In another such nozzle, the outlet portion defines a plurality of substantially concentric, substantially elliptical-shaped outlet apertures. In another nozzle, the outlet portion is formed of ceramic and is connected to the inlet portion by a metal connector.

  • Patent number: 9221274
    Abstract: Method for direct printing on containers via a direct printing machine, with a print layer printed onto the container, in a first predefined area, in a first device, and a cover layer applied to the container in a second device, the cover layer applied to a second predefined area. A surface area of the second predefined area is larger than that of the first predefined area. The cover layer coalesces with the printing ink in the first predefined area, creating a first connection, and coalesces with the container in parts of the second predefined area differing from the first predefined area, creating a second connection. The first and second connections are insoluble in aqueous solutions having a pH value between 3 and 10 and easily soluble in aqueous solutions having a pH value in a range of less than 3 and/or higher than 10.

  • Patent number: 9206703
    Abstract: A system and method for washing a jet engine of an aircraft are disclosed. The method comprises creating a collecting bowl under the jet engine by coupling a suit to the jet engine of the aircraft and coupling an apron of the suit to the jet engine. After the suit is coupled to the jet engine, a cleaning cycle is performed, which includes injecting cleaning fluid into the jet engine, turning over the jet engine, and collecting resultant effluent in the bowl. Further, the effluent remains in the bowl until actively removed by a user. The suit may be coupled to the aircraft by wrapping a strap around a pylon that couples the jet engine to the aircraft.
