  • Patent number: 10413112
    Abstract: Brewing assemblies/machines and related brewing methods for brewed beverages, such as coffee and tea. In some embodiments, the assembly may comprise a brew chamber and a steam chamber, which is configured for fluid communication with the brew chamber and may be positioned below the brew chamber. The assembly may further comprise one or more valve assemblies, such as a valve assembly configured to operate between an open position in which fluid may pass between the brew chamber and the steam chamber and a closed position in which fluid is prevented from passing between the brew chamber and the steam chamber. In some embodiments, the valve assembly may be configured such that steam pressure within the steam chamber causes the valve assembly to enter the open position.

  • Patent number: 10406625
    Abstract: This seam-welding device carries out seam welding while repeating one cycle comprising a melting period, an interruption period, and a heating period implemented either before or after the interruption period. A welding current is applied between a pair of roller electrodes so as to form a welded part between workpieces during the melting period, the application of the current between the roller electrode pair is interrupted so as to solidify the welded part during the interruption period, and a heating current smaller than the welding current is applied between the roller electrode pair so as to heat the laminated body within a solidification temperature range of the welded part during the heating period. Consequently, even when the welding speed is increased, formation of cracks and spatter is effectively suppressed such that a high-quality joined product is obtained.

  • Patent number: 10406627
    Abstract: By superposing a plurality of steel sheets including a high tensile steel sheet and performing pulsation conduction by an inverter DC type spot welding power supply and controlling the conduction time of the current pulses, intervals of the current pulses, that is, conduction idle time, and weld current applied at the current pulses in a variable manner, the optimum weld conditions are obtained. For resistance spot welding of the hot stamped steel sheet, resistance spot welding with a minimum weld current of a second pulsation step higher than the maximum weld current at a first pulsation step is used to suppress the occurrence of outer spatter and inner spatter and secure a broad suitable current range even if using an inverter DC power supply.

  • Patent number: 10399184
    Abstract: A method is provided for the internal processing of a transparent substrate in preparation for a cleaving step. The substrate is irradiated with a focused laser beam that is comprised of pulses having an energy and pulse duration selected to produce a filament within the substrate. The substrate is translated relative to the laser beam to irradiate the substrate and produce an additional filament at one or more additional locations. The resulting filaments form an array defining an internally scribed path for cleaving said substrate. Laser beam parameters may be varied to adjust the filament length and position, and to optionally introduce V-channels or grooves, rendering bevels to the laser-cleaved edges. Preferably, the laser pulses are delivered in a burst train for lowering the energy threshold for filament formation and increasing the filament length.

  • Patent number: 10365013
    Abstract: An ohmic heater for heating a conductive fluid includes electrodes (14) and spaces (20) between the electrodes. A controller (52) selectively connects the electrodes to a power supply (36) during a succession of actuation intervals so as to form conduction paths, each including two live electrodes connected to different electrical potentials, and the fluid in one or more spaces. The controller models fluid passing through the spaces as a series of finite elements moving through the spaces. Before each actuation interval, the controller estimates the expected results of actuating various possible conduction paths, including the estimated temperature of the fluid in the conduction paths and the estimated currents passing through the live electrodes. The controller selects a set of conduction paths for which the estimated results meet a set of constraints, and actuates only the selected conduction paths during the actuation interval.
