摘要： An apparatus for de-stacking sheet metal blanks uses electro-magnetic pulses to separate sheet metal blanks from a stack of blanks. A fixture supports an electromagnetic attraction device that includes one or more multi-turn electrical coils and one or more insulated metal screens. The coil is electrically connected to a bank of capacitors. The metal screen is disposed in an electrical insulation material and is retained by the fixture between the coil and the top blank of the stack of blanks. Suction cups perform the primary lifting function and are connected to a vacuum source. The suction cups may be supported by the same fixture or another associated fixture that cooperates with the coil and insulated screen.

摘要： A de-coupling mechanism includes a link slidably received in a link aperture of a bracket. A pin is slidably received in a pin bore of the link and a receiving bore of the bracket. A first block is connected to the bracket and includes an initiator receiving passage in communication with the pin bore. An initiator is positioned in the initiator receiving passage and retained against a connecting passage edge and oppositely contacts an end face of a cap connected to the first block. A second block connected to the bracket includes a longitudinal channel having a channel diameter larger than a pin diameter so the pin is freely displaceable into the longitudinal channel. An end face of a retaining cap is connected to a second block end wall. The retaining cap includes a stepped portion having a step diameter smaller than the channel diameter and the pin diameter.

摘要： A gradient energy system includes a membrane module including a first section, a second section, and a membrane separating the first section and the second section. A first gas may be provided within the first section. A second gas may be provided within the second section. The membrane module may be configured such that a differential associated with the first gas and the second gas generates a fluid pressure force or an electrical current. A method of recovering energy from gradients of gas mixtures may include providing a first gas to a first section of a membrane module, providing a second gas to a second section of the membrane module, which may be separated from the first section by a membrane, and/or recovering energy generated via a differential between the first gas and the second gas.

摘要： A system and apparatus is disclosed for controlling a restraining force applied to a panel. The apparatus includes a die, a binder supporting the panel against the die, and a punch used to draw the panel into the die. A restraining element is disposed on one of the die and the binder that engages a surface of the panel and applies a restraining force onto the panel. A strain gauge is disposed inside at least one of the die and the binder that engages a surface of the panel to measure the restraining force applied to the panel. The level of restraining force applied by the restraining element onto the panel is controlled based upon the restraining force measured by the strain gauge.

摘要： In an example of a selective, real-time gas sensing method, a gas sample, potentially including a specific gas molecule to be sensed, is supplied to an interface between a working electrode and an ionic liquid electrolyte. Based on at least one unique electrochemical reaction of the specific gas molecule to be sensed, a driving force is implemented to initiate a series of reactions involving the specific gas molecule. In response to the implementation of the driving force, a signal indicative of the specific gas molecule is monitored for.

摘要： A method for measuring localized stretching of a manufactured part or in a test sample of various materials to identify the fracture strain or strain distribution. The method begins by etching or printing a grid of a plurality of cells on a surface of a blank. Dots of paint are then applied to the surface of the blank that are measured in a pre-forming condition and identified as to the location of the dots relative to the grid. The blank is then formed into a formed part and the dots are measured in one or more cells in a post-forming condition. The size of the dots in the pre-forming condition is compared to the size of the dots in the post-forming condition to determine the extent of stretching in localized areas of the formed part. The method may be repeated for successive operations with different colored dots.

摘要： An alkane gas is supplied to an interface between an activated surface of a platinum or palladium working electrode and an ionic liquid electrolyte. The alkane adsorbs at or near an interface complex formed at the interface. The ionic liquid electrolyte is selected from a group consisting of 1-ethyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-propyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1 -pentyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-hexyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1 -heptyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1 -octyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1 -nonyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, and 1-decyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imidem, and combinations thereof. While the alkane gas in the presence of oxygen is supplied to the interface, positive electrode potential is applied to the platinum or palladium working electrode, which causes oxidation of the adsorbed alkane to form a reaction product. A concentration of the alkane is quantified using an alkane anodic current or current density at the positive electrode potential. The alkane is used as an internal standard to calibrate oxygen detection.
