Abstract: An active winglet includes a body portion substantially parallel to a wing of an aircraft, as if it were an extension of the wing, and an angled portion that projects at an upward angle from the body portion. The body portion is attachable to an aircraft wing and includes a controllable airflow modification device coupled thereto. By virtue of having a controllable airflow modification device, the winglet is capable of adjusting a control surface of the controllable airflow modification device in response to in-flight conditions, to reduce wing loads, increase range, and increase efficiency.

Abstract: A single-use, self-heating or self-cooling container, particularly for beverages, producible in a plurality of sizes, comprises a first receptacle (2) containing a beverage and inserted into a second receptacle (3), a first compartment (11) formed between the first and the second receptacle and a second compartment (12) formed on the base of the second receptacle and separated from the first compartment by a breakable diaphragm (13). In these compartments (11, 12) are separately and respectively arranged at least a first and a second component of an exothermic or endothermic reaction, and the first component is arranged in the first compartment (11) annularly around the first receptacle (2), while the diaphragm (13) extends as a separation of these compartments substantially against the base (4) of the first receptacle.

Abstract: A vehicle acceleration control and release device operatively connectable to a vehicle acceleration device, includes a device body; a lever operatively connected to the device body and pivotable about a first axis for controlling vehicle acceleration and pivotable about a second axis for releasing acceleration control, the first axis being perpendicular to the second axis.

Abstract: Tools for setting precious and semi-precious stones in metal, and methods for using such tools to set such stones quickly and to accomplish such setting in the absence of chisel marks in the finished products. A first tool includes a disc-shaped rotating grinding member that has a beveled cutting edge for trimming excess metal prior to making the setting. A second tool has a disc-shaped rotatable cutting member having a kerfed cutting edge that produces parallel channels in such metal to thereby define a linear bar means therebetween which bar is manipulated by a conventional tool to form beads that retain the stones within their respective settings. The inventive method contemplates the use of the beveled edge tool to form beveled reflective surfaces on opposite sides of the stone, and use of the kerfed-edge tool thereafter to form the bead-producing bars. An alternative method contemplates using the kerfed edge tool first, followed by the beveled edge tool.

Abstract: This invention concerns an improved combustion chamber comprising two concentric sheet metal cases forming a space into which air is admitted. The air passes from the space to the interior of the chamber in primary, secondary, annular, and tertiary air flows. The fuel coming from lateral nozzles forms a flame which is directed at first toward the closed end, then turned back by the secondary air flow. The external case comprises two walls between which a cooling flow circulates. The invention thereby achieves reduction in atmospheric pollution from exhaust gases.
