摘要:
A composite, heavy duty rotary concrete mixing drum (16) for coupling to a vehicle having a drivetrain (18) for rotating the drum (16) comprises a wall and a drive ring. The wall defines a first end of the drum and a second end of the drum. The drive ring (39) is coupled to the first end of the drum and includes a hub (108, 252) and a plurality of extensions (110, 254). The hub is operatively coupled to the drivetrain. The plurality of extensions (110, 254) extend outwardly from the hub (108, 252) into the wall of the drum. At least one of the extensions includes an aperture (121, 126) extending therethrough. Rotation of the hub by the second drivetrain causes rotation of the drum.

A heavy duty rotary concrete mixing drum (16) for coupling to a vehicle (10) having a powered drivetrain (18) for rotating the drum comprises a wall and at least one projection (32). The wall (33) includes an inner surface (34) defining a volume and an outer surface (36). The at least one projection is coupled to the wall and extends from the inner surface of the wall. The projection includes a body and a support member (48) disposed within the body.

Cell membranes containing glycolipid-enriched membrane (GEM) and non-glycolipid-enriched membrane (non-GEM) domains are targeted using fusion proteins that are anchored in the cell membrane. Fusion proteins to target GEM (or non-GEM) domains are comprised of a selected fluorescent polypeptide, a membrane-targeting sequence of p56 lck (or pp60 c-Src for non GEM domains) and a linker inserted between the polypeptide and the membrane targeting sequence. Localization of fusion proteins in GEM and non-GEM domains is assessed using techniques including confocal microscopy, fluorescence-based techniques, and membrane fractionation. Using these techniques, compounds are screened for their effect on GEM and non-GEM domains of live cells. These fusion proteins therefore represent useful tools for studying subcellular trafficking and the function of discrete compartments in the plasma membrane.

A multi-temperature and multi-texture frozen food microwave heating tray includes a first integral compartment defined by at least one sidewall and an upwardly convex bottom, and a second integral compartment defined by at least one sidewall and a bottom and comprising a microwave energy access modulating structure for one of the first and second compartments.

An apparatus for clarifying raw water containing suspended particulate matter comprises an upright conduit (1) with diameters increasing from an inlet for raw water at the top to an exit for clear water at the bottom. The inlet raw water is dosed with coagulant and/or flocculant and aerated with fine air bubbles before entry into the conduit. The bubbles become attached to flocs as they form in the upper part of the conduit. As the liquid descends in the conduit, the flaw velocity decreases enabling the flocs to float counter to the water stream and form a floating body within the conduit which functions as a filter medium. Clear water flows out of the conduit under an underflow weir and the outflowing clear water is raised by an exit duct to a level ensuring the duct remains full of water. Accumulated material is extracted from the bottom of the body through a co-axial discharge duct at a rate substantially equal to the rate of increase of fresh material from the influent raw water so that a steady state condition is achieved.

Disclosed is a method for removing carbon dioxide from the atmosphere. The method comprises the step of delivering urea from a floating vessel to a region of a photic zone of the ocean, whereby the number of phytoplankton is caused to increase in the region upon addition of the urea. The method can be used for producing carbon cells.

A concrete batch plant (1) includes a frame (2), a cement supply (3), an aggregate supply (4) and a transit mixer drum (6) having an open end and a closed end. The drum is pivotally coupled to the frame for movement between a first maintained position in which the open end is positioned to receive cement from the cement supply and to receive aggregate from the aggregate supply and a second maintained position in which the open end is positioned to discharge mixed cement and aggregate.
