  • Publication number: 20120052027
    Abstract: The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, there by allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.

  • Patent number: 7950466
    Abstract: A wellhead system, connector, and method of assembling a wellhead system. The connector includes a member having a set of left-hand threads and a set of right-hand threads on its interior surface. The connector provides a quick connection to threads on wellhead components such as a tubing head and a casing head.

  • Publication number: 20100323134
    Abstract: The present invention is a laminate and resultant package expressing an aroma burst. The laminate or package is comprised of a polyolefin sealing layer; a pressure sensitive adhesive layer and microcapsules containing an active core material, the microcapsules dispersed in a resealably tacky pressure sensitive adhesive layer; the pressure sensitive adhesive sandwiched between at least two layers by being disposed along substantially an entire surface of the polyolefin sealing layer and in continuous and direct contact with a second polyolefin layer opposing and coextensive with the polyolefin sealing layer; and the microcapsules in the pressure sensitive adhesive layer having less tensile strength than the adhesive such that a fraction of the microcapsules rupture releasing core material such as an aroma or fragrance when the pressure sensitive adhesive layer is separated when the polyethylene and first polyolefin layers sandwiching the pressure sensitive adhesive are pulled apart.

  • Patent number: 7235308
    Abstract: A coated paper stock having high moisture vapor barrier characteristics and ingredient compatible with recycling and repulping is disclosed comprising a substrate coated on at least one surface with a subcoat. The subcoat comprises a hydrolyzed amphoteric vegetable protein at at least 11 weight percent based on weight of the subcoat. A top coat is coated over said subcoat. The top coat consists essentially of a water-based dispersion of a film forming vinyl addition polymer, conjugated diene polymer or copolymer of either polymer, such as acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, styrene acrylate copolymers, styrene butadiene copolymers, polyvinylidene chloride and polyvinylidene chloride copolymers. The top coat is substantially free of mineral pigments that interfere with the moisture vapor barrier characteristics. The vegetable protein is preferably a hydrolyzed amphoteric soybean protein with an average molecular weight less than 400,000 Daltons.

  • Patent number: 6570503
    Abstract: An emergency signal device for use by those with medical conditions having means to detect the occurrence of a change in attitude in conjunction with a shock and an alarm means including audible messages alerting bystanders to the wearer's medical problems. The emergency signal device may also include means to activate the alarm means in the event the wearer exits a pre-specified geographic area, or at pre-specified time intervals. The emergency signal device may also include cellular and global positioning satellite means to automatically determine and transmit the location of the emergency signal device to a cellular base station upon activation of the alarm. The emergency signal device may further include means for activating existing emergency telephone notification systems.

  • Patent number: 5135266
    Abstract: A method and an apparatus for attaching an upper wellhead housing to casing employs a combination slip and seal assembly. An annular metal slip member is supported by a lower wellhead housing. The slip member has a conical section with an annular external seal. The interior of the slip member contains circumferential teeth. When the upper wellhead housing is placed over the slip member and clamped to the lower wellhead housing, it wedges the slip member radially inward. The internal teeth will embed against the casing to grip the casing. The external seal seals against the upper wellhead housing bore conical surface. A retaining ring engages the slip member and locates between mating shoulders of the upper and lower housings to limit downward travel of the slip member.

  • Patent number: 3962268
    Abstract: A process for the manufacture of 2:2'- or 4:4'-bipyridyls which comprises heating a 2- or 4-(halo-magnesium)-pyridine respectively with a halogen or the halide of an element from groups 4b, 5b, 6b, 7b, 8, lb, 2b, 3a, 4a and 5a of the Periodic table. Typically the process involves heating grignard reagents from 2- or 4-bromo pyridine with bromine or silver copper or cobalt chlorides or bromides at 40.degree. to 130.degree.C.Bipyridyls are useful as intermediates for herbicide manufacture.
