Concrete stamping apparatus
TLDR
A concrete stamping apparatus includes a roller with a stamp forming its surface, and a receiving portion for rotatably holding the roller as mentioned in this paper, which can be adjustably weighted such that the roller will stamp the concrete uniformly as the concrete tightens.Abstract:
A concrete stamping apparatus includes a roller with a stamp forming its surface, and a receiving portion for rotatably holding the roller. There is also a system for delivering fluid to the release the roller from the surface on which it operates by spraying fluid onto the ground surface in advance of the roller. The receiving portion can be adjustably weighted, such that the roller will stamp the concrete uniformly as the concrete tightens.read more

Device for producing tactile-detectable warning surfaces and method for employing same
TL;DR: In this paper, the authors proposed a tactile-detectable warning surface in moldable concrete or asphalt and a method for employing the same, which consists of a mold member having truncated dome shaped indentations distributed therein in a warning pattern, each indentation optionally having an air hole located centrally therein, and, form rails distributed between indentations on the lower surface of the mold member and projecting downward there from, so as to force an even and consistent distribution of the mouldable material into the indentations when the form rails are worked downward into the surface of moldable material

Methods for enriching specific cell-types by density gradient centrifugation
TL;DR: In this paper, a cell-trap centrifugation tube containing a specific density gradient solution adjusted to the specific density of a desired cell population was used to enrich for the desired cell from a cell source.
Patent
Method and apparatus for fluid handling and separation
TL;DR: In this paper, the authors describe a method to separate liquid layers by means of a resilient bung 46 which is forced downwardly through layer 44 (the displaced liquid passing around or through the bung) until it arrives at the interlayer boundary.
Patent
Apparatus for the separation of biologic components from heterogeneous cell populations
TL;DR: A disposable separation inset for use in association with a rotatable separation device of the apparatus may also be provided as discussed by the authors, which includes a chamber for receiving a cell suspension that includes the target cell, a receptacle for containing particles having a binding site for selectively binding to the target cells and a means for introducing the particles into the chamber.
