摘要:
A transformable towel dispenser is presented that can be quickly transformed from a low profile shipping form into a full, ready to dispense form in a substantially tool free manner. The transformability of the dispenser allows the dispenser to be shipped and stored in much smaller space than that for ready to dispense units. Alternatively, more dispensers can be shipped in the same volume container.
摘要:
The present invention generally relates to a new method of polymerizing ethylene. In one embodiment, the present invention relates to compounds utilized in the polymerization of ethylene and to a synthesis/polymerization method that uses same. In another embodiment, branched polyethylene is synthesized from an ethylene monomer using, in this embodiment, at least one nickel iminophosphonamide (PN 2 ) complex. In still another embodiment, the reaction of (phenyl) (triphenylphosphine) (diphenyl-bis (trimethylsilylimino) phosphorato)-nickel with Rh(acac)(C 2 H 4 ) 2 and ethylene yield a branched polyethylene. In an alternative of this embodiment, the reaction of (phenyl) (triphenylphosphine) (methyl-bis(trimethylsilyl) amino-bis(trimethylsilylimino) phosphorato)-nickel and ethylene, with or without Ni(COD) 2 , yields a branched polyethylene.

摘要:
A fluid heating apparatus comprising a chamber for containing a quantity of fluid to be heated and a heating device in the chamber. The heating device comprises a hollow body having a flow inlet and a return outlet to allow a heating medium to flow through the hollow body. The hollow body has a first heat exchanging surface extending along the chamber between a fluid inlet and fluid outlet and defining a smooth, straight fluid passage between the inlet and outlet. The preferred apparatus takes the form of a thermosyphon and is particularly suited for use with a water storage tank, where it is arranged to cause thermosyphonic circulation of water between the thermosyphon and the tank.
摘要:
An electrochemically activated fluid (20, 22, 44, 45, 51, 52, 190, 192) is provided, which has an anolyte and a catholyte. For example, a sparged anolyte and a sparged catholyte (51, 52) are provided. In another example, a combined anolyte and catholyte (71, 160) is provided.
摘要:
An adapter for a cup dispenser that can be used to replace flexible diaphragms so as to improve wear characteristics. Each adapter is preferably interchangeable with other adapters sized to accommodate other different cup sizes and shapes. The adapter includes two or more rows of preferably offset restrictions to stage and separate cups for easy dispensing. The invention also comprises a cup dispenser incorporating such an adapter and a method of interchanging a flexible diaphragm with such an adapter.

摘要:
A grid structure and method for manufacturing the same. The grid is used for gating a stream of charged particles in certain types of particle measurement instruments, such as ion mobility spectrometers and the like. The methods include various microfabrication techniques for etching and/or depositing grid structure materials on a silicon substrate.
摘要:
Tissue engineered constructs and methods for fabricating the disclosed constructs are provided. Some of the disclosed tissue engineered constructs are designed to fill a void in the body due to surgical resection, for example from mastectomy or lumpectomy, wounds and the like. Some disclosed constructs comprise one or more projections designed to mimic the appearance of a structural feature when implanted into a host.
摘要:
An automated storage and retrieval system for storing chemical and biological samples includes freezer chests maintained at an ultra-low temperature (e.g. -80°C) or a cryogenic temperature. The freezer chests are located within a refrigerated (e.g. -20°C) enclosure (10). Samples are loaded through a wall of the enclosure and are then transferred to an input/output buffer section (38) in an ultra-low temperature or cryogenic freezer chest (11) that is thermally segregated (40) from a long-term storage section (36) in the same freezer. Specialized input/output cassettes are used for transferring the samples through an input/output module (14) into the system.
