Abstract: In accordance with at least one aspect of this disclosure, a method includes flushing a cell stack for a predetermined amount of time as a function of an amount of combustible gas remaining in the cell stack. The method also includes operating a cell stack for a predetermined amount of time, then shutting down the cell stack and ceasing operation of the cell stack for a predetermined amount of time. Flushing occurs after shutting down a cell stack power supply. The method further includes restarting operation of the cell stack after flushing.

Abstract: The present invention relates to a cell which comprises a chimeric antigen receptor (CAR) or transgenic T cell receptor (TCR) and secretes an antibody which binds a transforming growth factor beta receptor (T?R).

Abstract: A portable shelter is erectable on a support surface for providing short to long term housing for humans. In general, the shelter includes a foundation, a floor supported by the foundation, and an enclosure. The shelter defines an interior which may be inhabited by a human. The shelter may include front, rear, side, and top walls, all of which may be folded to define inboard and outboard folds which enhance the structural integrity of the walls. The floor of the structure may include indentations corresponding to inboard folds of one or more walls for receiving the inboard folds for enhancing structural integrity of the shelter. The floor may be folded to form upstanding portions adjacent the indentations for securing the inboard folds in the indentations. Moreover, the walls may be folded to define feet which engage the support surface.

Abstract: A lightweight bed assembly kit includes slats and runners adapted for connection to each other at spaced apart locations to form a grid. A U-shaped channel member is adapted for connection to the grid to form a support frame. A covering constructed to form a substantially smooth sleeping surface for an adult human is sized and shaped to be disposed on a top surface of the support frame. A method of assembling a lightweight bed includes arranging runners and slats transversely to each other and connecting the runners and slats together to form a grid. A U-shaped channel member is connected to the grid to form a support frame. A covering constructed to form a substantially smooth sleeping surface is mounted on a top surface of the support frame. A second support frame can be connected to the first support frame by another U-shaped channel member.

Abstract: The present invention generally relates to an extruded thermoplastic board having a light weight relative to its thickness, as well as enhanced mechanical strength relative to its weight. More specifically, the present invention relates to an extruded, thermoplastic board that is corrugated (e.g., a board containing internal ribs), that is both thick and light weight, and that has enhanced mechanical strength. The present invention is additionally directed to a process for preparing such a board.
