Abstract: A mixing chamber assembly which has a reciprocating rod received within a mixing chamber of a mixing chamber member. The reciprocating rod is in a non-interference position with the mixing chamber over its entire length within the mixing chamber. The non-interference fit provides for continuous solvent flow about the exterior of the rod and interior of the wall defining the mixing chamber such that solvent drips out the discharge end of the mixing chamber and the rod is free to float or ride on a film of solvent. The term "solvent" can include a combination of solvent and other ingredients such as lubricants, emulsifiers and flow control particles. The ability for the rod to ride on a film of solvent over the entire portion received within the mixing chamber, allows for a much reduced reciprocating motive force requirement and a corresponding freedom to increase the mixing chamber volume.

Abstract: A pillow includes a first main face having an essentially planar main surface. This planar main surface includes a head receiving recess. The second main face of the pillow, located opposite the first main face, includes a plurality of extending fingers arranged in rows, wherein the fingers extend such that a base of the finger is located closer to the first main face than is the tip (or free end) of that finger. The fingers are of a length such that the finger tips essentially lie on a common plane which is essentially parallel to the essentially planar main surface of the first main face. Several recesses are defined in the area between a finger and the surrounding, adjacent fingers of the second main face. In particularly preferred embodiments of the pillow, the recesses between adjacent fingers extend through the pillow so as to provide vent holes through the pillow in the area of the head receiving recess.
Abstract: An apparatus and method for forming flat top foam buns or slabs which features positioning solely one sheet of film material to each side of a rising foam body. The single side sheet is positioned in contact with the rising foam on one side and in contact with a rigid side wall on the opposite side. Also, the single side sheet positioned between the rising foam and stationary side wall represents the only material between the side wall and foam material. The side film has a bottom edge which originates below a reference plane lying flush on the bottom supporting surface of the foam bun once it has reached an essentially full rise position. Preferably, bottom and side conveyors are provided near the full rise position of the foam material and the side film is redirected from an upwardly inclined edge arrangement to a horizontal edge arrangement.
Abstract: A padding body that has flexible grid member with apertures formed in it. The apertures are defined by bordering sections of the grid member. The padding body includes individual modular elements with each modular element being resilient and each modular element having an intermediate section and an upper protuberance extending upwardly off from the intermediate section. The individual modular elements have a peripheral slit or recess formed in the intermediate section. Each of the individual modular elements are releasably fixed within a respective one of the apertures formed in the grid. One embodiment of the padding body includes a frame structure formed entirely of foam material. The frame structure includes foam blocks stacked two high. Apertures and the bordering sections of the grid member spaced about the periphery of the grid member are secured between the upper and lower stacked foam blocks so as to suspend the grid member.
Abstract: A girder support for a girder having a web and a top flange, the support is formed of extruded aluminium and is of a "T-shaped" configuration with a recess which encompasses the web and top flange, the support includes two legs between which the web is located, with the legs being resiliently movable away from each other to facilitate installation of the support.
