  • Patent number: 11947873
    Abstract: An exemplary method for identifying media may include receiving user input associated with a request for media, where that user input includes unstructured natural language speech including one or more words; identifying at least one context associated with the user input; causing a search for the media based on the at least one context and the user input; determining, based on the at least one context and the user input, at least one media item that satisfies the request; and in accordance with a determination that the at least one media item satisfies the request, obtaining the at least one media item.

  • Patent number: 11933076
    Abstract: An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electromechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state.

  • Patent number: 5878699
    Abstract: A twin-cell furnace for process stream preheat and utility steam superheat. The furnace uses a pair of vertical radiant cells with top supported, bottom guided, single row, multiple pass vertical coils fired on opposite sides by floor-mounted burners. An overhead convection section is centered between the radiant cells. Induced and forced draft fans are placed over the convection section to draw combustion gas into the stack and supply air through an air preheater, between the convection section and the stack, and to the floor burners and supplemental convection section burners. Additional convection coils are positioned in the hip section between the radiant cells and the convection section. The furnace design has reduced plot space requirements, increased flexibility in heating multiple services, and allows more even heating of the radiant tubes, and easier radiant tube replacement.

  • Patent number: 4895622
    Abstract: This invention relates to an improved press felt conditioning treatment which controls the deposition of polymerically flocculated particulate substances in a press felt. The treatment comprises applying to the felt an effective inhibiting amount of a conditioner comprising a relatively low molecular weight organic, anionic polymer and at least one hydrophilic, nonionic or anionic surfactant. The polymer preferrably has an acrylic acid or methacrylic acid functionality and is preferrably selected from the group consisting of homopolymers of acrylic acid, a methacrylic acid/polyethylene glycol allyl ether copolymer, a homopolymer of methacrylic acid, an acrylic acid/polyethylene glycol allyl ether copolymer, and an acrylic acid/1-allyloxy-2-hydroxypropane sulfonic acid copolymer.

  • Patent number: 4861429
    Abstract: This invention relates to a process for inhibiting white pitch deposition in felts of a papermaking system including adding to the felts an effective inhibiting amount of an organic, anionic polyelectrolyte. The molecular weight of the polyelectrolyte is preferably from about 1,000 to 100,000. The polyelectrolyte is selected from the group consisting of polyacrylic acid, polmethacrylic acid, acrylic acid/polyethylene glycol allyl ether copolymers, methacrylic acid/polyethylene glycol allyl ether copolymers, acrylic acid/1-allyloxy-2-hydroxypropane sulfonic acid copolymers. The use of these polyelectrolytes in combination with surfactants provides an especially effective white pitch inhibiting and total felt conditioning process when applied to the felt.

  • Patent number: 4767662
    Abstract: Copper etching process and product particularly suitable for use in the manufacture of printed circuit boards. The copper is etched in a liquid etchant, and the crystal structure of the copper is selected and carefully controlled to provide an anisotropic etch and a relatively high vertical-to-lateral etching ratio. In one disclosed embodiment, the etching solution contains nitric acid, copper nitrate or sulfuric acid, a polymer and a surfactant, and the copper has a top surface crystal structure with predominantly (111) to (200) orientations and relatively little (220) orientation. In another disclosed embodiment, the etching solution contains hydrogen peroxide and sulfuric acid, and the copper foil has a top surface crystal structure with predominantly (311) and (511) orientations and/or (111) and (200) orientations.

  • Patent number: 4767661
    Abstract: Copper etching process and product particularly suitable for use in the manufacture of printed circuit boards. The copper is etched in a liquid etchant, and the crystal structure of the copper is selected and carefully controlled to provide an anisotropic etch and a vertical-to-lateral etching ratio greater than 1:1. In one disclosed embodiment, the etching solution contains nitric acid, copper nitrate or sulfuric acid, a polymer and a surfactant, and the copper has a top surface crystal structure with predominantly (111) orientation. In another disclosed embodiment, the etching solution contains hydrogen peroxide and sulfuric acid, and the copper foil has a top surface crystal structure with predominantly (311) and (511) orientations and/or (111) orientation.

  • Patent number: 4715931
    Abstract: This invention relates to process for inhibiting deposition of aluminum hydroxide in felts of a papermaking system which comprises adding to the felts an effective inhibiting amount of a hydroxylated carboxylic acid having at least 1 hydroxyl group and at least 2 carboxyl groups. The molecular weight of the carboxylic acid is from about 100 to about 200 and, preferably, the carboxylic acid is selected from the group consisting of tartaric acid, malic acid, citric acid, mesoxalic acid, tartronic acid and tetrahydroxy succinic acid. The use of these carboxylic acids in combination with surfactants provides an especially effective aluminum hydroxide inhibiting and total felt conditioning process when both components are applied to the felt.
