Abstract: A filter basket for a beverage machine includes a sidewall and a strainer portion. The filter basket forms a brew chamber into which ground coffee or other products are added. The brew chamber is defined by a sidewall, a strainer surface, and a smooth contour between the tapered sidewall and the strainer surface. The brew chamber is defined by smooth lines to create better fluid flow through the extraction process. A plurality of apertures are formed in the strainer surface to filter out large particles while allowing brewed beverage to flow therethrough. The tapered sidewalls in combination with the strainer surface, the smooth contour, and the unique pozzetto shape, result in a pressure profile and fluid flow characteristics that reduce the tendency of channeling through the ground coffee and result in a more consistent and uniform extraction.

Abstract: The present disclosure is directed to systems and methods for pretreating a wire that is used in a welding operation to reduce the amount of hydrogen introduced into a weld. Using embodiments of the systems and methods disclosed herein, one passes a wire through a pre-treatment chamber in which a wire is treated to release hydrogen and/or other contaminants, and provides a gas flow through the pre-treatment chamber so that the contaminants that are released from the wire are taken up by the gas. The gas exiting the pre-treatment chamber may be isolated from the shielding gas utilized during a welding operation. For instance, the pretreatment gas may be directed away from the distal end of the welding torch, thereby preventing released contaminants from being transported into a weld.

Abstract: A plurality of substrate support pins are provided upright on a holding plate so as to contact a position on which no stress is exerted in a lower surface of a semiconductor wafer when an upper surface of the semiconductor wafer is irradiated with flash light emitted from a flash lamp and thus reaches a maximum temperature.

The semiconductor wafer can be prevented from breaking during the application of the flash light.
