A composite part charge having an internal cavity is placed on a tool and covered by a vacuum bag for autoclave curing. A bladder is placed in the cavity to react autoclave pressure on the charge. The bladder is coupled with a flexible fluid reservoir located beneath the vacuum bag. The bladder is pressurized by autoclave pressure applied through the vacuum bag to the flexible fluid reservoir.

A foam molding shell for a centrifuge bowl, a bowl for a centrifuge, a method for producing a thermal insulation encasing the bowl for the centrifuge and to a centrifuge. The foam molding shell is configured as a disposable tool for foam encasing the bowl for the centrifuge with the thermal insulating material. Thus, the production complexity and the production cost of the centrifuge bowl with the thermally insulated bowl for the centrifuge can be significantly reduced.

Methods and apparatuses for using microfluidics to generate bubbles and using the generated bubbles to construct scaffolds and cell-holding structures for culturing biological samples or analytes. In one implementation, a scaffold for growing cells is provided to include a matrix of interconnected cavities formed from mixing a gas and a liquid containing a cross linkable material to produce a matrix of gas bubbles of substantially the same size and cross linking the cross linkable material to form a structure in which cells are grown. In another implementation, a scaffold apparatus for growing cells includes a ball of a cross linked material forming an exterior shell that encloses to form a hollow interior inside the ball and biological samples embedded in the external shell.

A method for manufacturing including securing attachments disposed near both ends in the seat core member front portion made of a molded article of expanded beads, the securing attachments being connected by an embedded connecting member extending in the seat core member longitudinal direction. The securing attachment includes a base embedded in the molded article of expanded beads, an upright frame joined to the base to extend out of the molded article of expanded beads, and a securing portion extending from the upright frame to project away from the molded article of expanded beads. The method includes creating, during or after molding the molded article of expanded beads, a space or notch in an outer side of the securing attachment upright frame of the molded article of expanded beads in the seat core member longitudinal direction, the notch extending toward an outer side in the seat core member longitudinal direction.

A method for the continuous production of pre-insulated piping having an inner metal carrier pipe having an interior surface and an exterior surface and an envelope of foamed insulation surrounding the inner metal carrier pipe exterior surface. A molding apparatus is provided for forming an annulus about a pipe to be insulated into which foam can be injected. The pipe is continuously moved through the apparatus with foaming material being injected into the annulus a where it is molded and cured to form a foam insulated pipe. The molding apparatus is a roller-drum having a cylindrical length and a plurality of individual rollers arranged in a series of linearly staggered, circular arrays which define the annulus where the foaming material is cured.

A nonwoven fabric used for a foamed article reinforcing material to be bonded to a foamed material to reinforce the foamed article is a single-layer material in which stacked layers of a web are bonded together, has a thickness of 1 to 8 mm under a load of 7 g/cm.sup.2, and has a delamination strength of 0.05 to 2.45 N/cm. The delamination strength is a value of the pulling force required to peel the bonded layers of the web apart.
