Patent number: 7621669Abstract: An assembly is mounted to a soft serve confection freezer. It includes a set of modules in a circular array and separately replaceable in a magazine. Each module supports a container storing a dry food ingredient in particulate form, and has a motor driven product impeller for controlled discharge of particulates from the container to a blender assembly. The blender assembly has a housing and screw-type auger of cooperating configurations and which cooperate with a central passageway for frozen confection flowing from the freezer, to blend solids into the confection and discharge into a customer's container for immediate consumption. Control panel selection of ingredients by the operator according to the customer's order, is provided. Components are arranged to facilitate cleaning. A system for control panel selection by the operator of liquid additives to the flowing confection, is provided to accommodate the customer's order.Type: GrantFiled: July 14, 2005Date of Patent: November 24, 2009Assignee: Flavor Burst Co., L.L.P.Inventor: Ernest C.

Patent number: 7537376Abstract: This invention relates to a device for a continuously operated dilution of a slurry sample, through which device the slurry sample is fed directly into a continuously operated optical analyzer, such as a grain size analyzer. The device comprises elements for feeding the slurry sample, elements for feeding diluting liquid and elements for removing solids contained in the slurry, as well as elements for discharging both the liquid contained in the slurry and the liquid used for dilution. The device of the invention comprises at least one downwardly narrowing chamber (2, 31) that is connected to the analyzer measurement cell (3, 34) so that two opposite walls (10, 32) of the chamber (2, 31) are essentially parallel both with respect to each other and with respect to the respective walls (21, 35) of the measurement cell (3, 34).Type: GrantFiled: February 4, 2004Date of Patent: May 26, 2009Assignee: Outotec OyjInventor: Christian Von Alfthan

Publication number: 20090131543Abstract: The present invention generally relates to multiple emulsions, and to methods and apparatuses for making multiple emulsions. A multiple emulsion generally describes larger droplets that contain one or more smaller droplets therein. The larger droplets may be suspended in a third fluid in some cases. These can be useful for encapsulating species such as pharmaceutical agents, cells, chemicals, or the like. In some cases, one or more of the droplets can change form, for instance, to become solidified to form a microcapsule, a liposome, a polymerosome, or a colloidosome. Multiple emulsions can be formed in one step in certain embodiments, with generally precise repeatability, and can be tailored to include one, two, three, or more inner droplets within a single outer droplet (which droplets may all be nested in some cases).Type: ApplicationFiled: March 3, 2006Publication date: May 21, 2009Inventors: David A. Weitz, Darren Roy Link, Andrew S. Utada

Publication number: 20080192566Abstract: The liquid mixing device has an operative mixing unit having an inside which is substantially hollow; and an injection unit provided in the inside of the operative mixing unit. The injection unit is adapted for allowing a second liquid to be injected into the inside of the operative mixing unit, and the operative mixing unit is provided with: an inlet port for allowing a first liquid to flow thereinto; and an outlet port. The injection unit is provided with an injector element of a tubular form which has: an injection hole(s) so perforated therein as to face toward the outlet port; and an opening region defined therein so as to allow the first liquid to pass rectilinearly therethrough in a direction from the inlet port toward the outlet port. The injector element may be of a generally ringed shape or of a generally “U” shape.Type: ApplicationFiled: April 14, 2006Publication date: August 14, 2008Applicant: HSP CO., LTD.Inventors: Koji Yamashita, Masayuki Shigemoto, Motoi Masuda

Patent number: 7347939Abstract: An adjustable contaminated mixing apparatus includes a reactor head and a down tube extending from the reactor head. A plurality of ports are formed in the reactor head and configured to impart a spinning motion to the contaminated liquid as it passes from the reactor head into the down tube. Each port is adapted to receive a flow restrictor to permit selectively control of velocity and flow volume of the liquid through the down tube. Typically, the flow restrictors are removable flow restriction plugs inserted into in a removable cartridge of the reactor head.Type: GrantFiled: March 25, 2004Date of Patent: March 25, 2008Assignee: Clean Water Technology, Inc.Inventors: Dwain E.
