  • Patent number: 10654016
    Abstract: There is provided an apparatus and a method for producing a play compound and the play compound itself which, in one embodiment is a compound which sufficiently fluid to be pliable and is typically cold and slimy to the touch. The apparatus and a method provide a powder and liquid to a user, which can be a non-skilled person and thereby allow the mixing of the powder and liquid together by that person to form the play compound outside of a factory environment whilst ensuring that the play compound which is formed has the desired characteristics. Most typically the user which performs the mixing can be the end user, such as a child, who will play with the compound and so the formation of the play compound forms a new part of the play experience.

    Abstract: An attachment to a mixer blade wipes the sides of a container and produces a mixture that is uniform and consistent. The attachment is placed onto the mixer blade either temporarily or permanently. After the attachment is on the mixer blade, the rotating spin of the mixer blade and the angular positioning of the flexible fins wipe the mixture on the sides of the container to the center of the container. By using a flexible material for the fins, the fins come into direct contact with the container while not damaging the container. The direct contact allows for the complete wiping of each side of the container. The attachment is easily cleaned.

    Abstract: A powder-fluidizing apparatus is presented which is applicable to feeding ultra-fine and nano-size powders, and powders with a broad particle size distribution, in a uniform manner over a long period of time. Generally, this is accomplished by using a rotating brush to sweep the powder through holes in a removable sieve plate, which breaks up agglomerated particles in the powder and controls the powder feed rate. The powder then drops from the holes into a funnel, where it is fluidized by being entrained into a carrier gas, and then flows through the funnel out of the apparatus to an applicator. The funnel surface is vibrated to avoid powder build-up on the surface that can break loose and cause pulses of increased material in the powder flow. Ultrasonic waves are introduced into the funnel to break up any agglomerated particles remaining in the powder before it reaches the applicator.

The flighting includes a first portion which is disposed helically around the core such that the feed is urged by the first portion in a direction from the first towards the second end of the core. Additionally, a second portion is disposed helically around the core such that the feed is urged by the second portion in the direction from the first towards the second end of the core. Also, the second portion is interposed between the first portion.

  • Patent number: 6694867
    Abstract: A scraper device includes a scraper fixture which is adapted to be placed in a working position adjacent to a surface to be scraped. At least one flex arm is connected at its proximal end to the scraper fixture and includes a distal end extending from the fixture toward the surface to be scraped when the scraper fixture is in the working position. A scraper plate is located at the distal end of the flex arm and extends at an acute scraping angle with respect to the surface to be scraped when the fixture is in the working position. In this position, a scraping edge of the scraper plate makes contact with the surface to be scraped to provide a scraping action as the scraper device is driven over the surface to be scraped.

  • Publication number: 20030123323
    Abstract: A device for mixing two paste like compounds, such as a dental molding compound using a catalyst for the acceleration of polymerization. The housing has a mixing area with at least two inlet openings for the compounds and an outlet opening for the mixed compound. The device also has a mixing element that is disposed in the mixing area and propelled around a longitudinal axis. The housing has a coupling section that is situated in front of the mixing area with two coupling openings for connecting with two dispensing openings of a device for dispensing the two paste like compounds. The first and second ducts connect to the couplings via the coupling openings extending through the coupling section into the inlet openings for the mixing area. The two ducts are formed so that the first duct requires a greater time of entry of the compound into the mixing area than the time required for the second compound flowing through the second duct.

  • Patent number: 6435707
    Abstract: Continuous mixing apparatus provide rapid production of a mixture of high uniformity, low viscosity, low density, high stability after mixing, without an increase in amounts of subsequently supplied liquids. Continuous production of liquid or liquid containing mixtures consists of (i) continuously loading the apparatus casing with materials of different types which are flowable such as different liquids or a powder and a liquid, (ii) mixing the components between independently rotating upper and lower bladed disk turbine impellers to form a coarse mixture, and (iii) mixing the coarse mixture with an additional portion of a liquid being continuously supplied to the casing. The apparatus includes upper and lower bladed disk turbine impellers disposed in a mixing chamber within a casing. The impellers are capable of being rotated independently at different rotational speeds. A plurality of blades are attached to the impellers. Upper and lower ring shaped baffles extend from the inner wall of the casing.

  • Patent number: 6431742
    Abstract: A continous mixing apparatus has an upper rotary disk and a lower rotary disk able to rotate independently of one another. A plurality of scrapers are attached to the upper and lower sides of the upper and lower rotary disks. Scrapers on the lower side of the lower rotary disk have a notch enabling the scrapers to pass over a lower ring plate in the mixer. Material to be mixed is supplied to an upper portion of the mixer, and the product is discharged from a lower portion of the mixer. The device is constructed to enable any subsequently replenished liquids to not rise to the top of the mixing apparatus. The device produces a mixture that is uniform, highly stable, and that has a small particle size or a low viscosity which can be manufactured quickly.

  • Patent number: 6403519
    Abstract: Process for the preparation of a catalyst for the polymerization of alpha-olefins involves contacting a porous polyolefin support with a solution containing an activator (ii) to form a suspension. The suspension is evaporated in a reactor fitted with a stirrer comprising a scraping element. The scraping element follows the walls of the reactor at a distance from 2 to 200 times the mean particle diameter of the support. The catalyst includes a compound of a transition metal (i) from Groups 4 to 6 of the Periodic Table and at least one optionally substituted cyclopentadiene ligand and an aluminoxane activator (ii). The aluminoxane activator (ii) and transition metal compound are supported on the porous polyethylene support (iii). The walls of the reactor show no traces of crusting.
