  • Patent number: 8349909
    Abstract: Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, an infrared attenuating agent, and a polystyrene/polyethylene oxide copolymer are provided. In exemplary embodiments, the blowing agent contains an HFC. The maleic anhydride-styrene copolymer grafted with polyethylene oxide increases the cell size of the polymer foam and offsets or even negates the decreased cell size caused by an HFC blowing agent and/or infrared attenuating agents. In addition, the copolymer of maleic anhydride-styrene grafted with polyethylene oxide has a positive affect on the processability of the blowing agent(s) in the composition by both widening the process window and enhancing the solubility of the blowing agent in the polymer melt. Thus, the polystyrene/polyethylene oxide copolymer present in the inventive composition acts as a cell enlarger, a plasticizer, and a processing aid. A method of forming an extruded foam product is also provided.

  • Patent number: 8347671
    Abstract: A lockout device is provided for an instrument having a body and an actuating member extending from the body for operating the instrument. The lockout device includes a bottom member, a cover member, and a flexible member. The bottom member and cover member are adapted to receive a cinching portion of the flexible member between first and second holding surfaces of the bottom member and cover member. When the flexible member is wrapped around a portion of the body and received between the first and second holding surfaces and the cover member is in a closed position, the first and second holding surfaces prevent movement of a cinching portion of the flexible member.

  • Patent number: 8341978
    Abstract: A method of forming high strength glass fibers in a refractory lined glass melter is disclosed. The refractory lined melter is suited to the batch compositions disclosed for the formation high modulus, and high-strength glass fibers. The glass composition for use in the method of the present invention is up to about 70.5 Weight % SiO2, 24.5 weight % Al2O3, 22 weight % alkaline earth oxides and may include small amounts of alkali metal oxides and ZrO2. Oxide based refractories included alumina, chromic oxide, silica, alumina-silica, zircon, zirconia-alumina-silica and combinations thereof. By using oxide based refractory lined furnaces the cost of production of glass fibers is substantially reduced in comparison with the cost of fibers using a platinum lined melting furnace. Fibers formed by the present invention are also disclosed.

  • Patent number: 8336051
    Abstract: A server architecture performs concurrent information processing in a server system on a multi-core processor environment. The architecture supports simultaneous processing requests comprising multiple classes of queries and/or executing transactions in an application server and/or database server. Requests, which are made in an asynchronous manner, are structured with hash values to enable similar requests to be grouped together. The similar requests are grouped into a group session. All of the requests in the group session are executed at the same time. Accordingly, similar database inserts can be grouped and executed as a single request. The architecture minimizes thread-switching overhead by exploiting inherent parallelism in the inflowing requests. The threads and requests are de-coupled and hence any lock request only makes the execution threads take up another request instead of waiting until the lock is acquired.

  • Patent number: 8327727
    Abstract: To eliminate or otherwise reduce unintended movement of a probe tip of a probe assembly being held by a probe arm, the probe assembly includes one or more resilient members that compensate for the contraction or expansion of the probe arm in accordance with the coefficient of thermal expansion of the material from which the probe arm is made. Thus, the probe tip can remain in contact with a sample being measured at the desired location on the sample, during an automated full or wide scale temperature range sweep.

  • Patent number: 8323787
    Abstract: Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, an additive blend of polyethylene oxide and a copolymer of polystyrene and maleic anhydride, and optionally, an infrared attenuating agent, are provided. In exemplary embodiments, the polyethylene oxide is ethoxylated polyethylene oxide. Additionally, in at least one embodiment, the blowing agent includes at least one hydrofluorocarbon blowing agent. The blend of ethoxylated polyethylene oxide and copolymer of polystyrene and maleic anhydride provides a water vapor permeability of 1.1 perm inch or greater in the extruded foam product and increases the average cell size of the foam product without detrimentally affecting physical or thermal properties of the product. Additionally, the additive acts as a cell enlarger, a water vapor permeability enhancer, a plasticizer, and a processing aid. A method of forming an extruded foam product is also provided.
