20130199412 | METHOD FOR PRODUCING A MOLDED PART FROM A CARBON MATERIAL USING RECYCLED CARBON FIBERS AND MOLDED PART - A method produces a molded part from carbon containing carbon fibers in an amount of less than 20% by weight. The method includes comminuting waste parts or scrap parts formed from a carbon fiber-reinforced synthetic material, a carbon fiber reinforced carbon or a carbon fiber reinforced concrete. A mixture is produced from the comminuted product, a binder such as pitch, a carbon material such as coke and optionally one or more additives, wherein the mixture contains less than 20% by weight of fibers. The mixture is molded into a molded part and the molded part is carbonized. Optionally, the molded carbonized part is impregnated with an impregnating agent. Finally and optionally, the molded carbonized part or the molded part impregnated part is graphitized. | 08-08-2013 |

20150064323 | SYSTEM, METHOD, AND APPARATUS FOR REGULATING FLOW RATE IN AN ESPRESSO MACHINE - Embodiments are directed towards regulating flow rate in an espresso machine, during a multi-phase brewing process which includes a pre-brew and an extraction phase. During the pre-brew phase, coffee grounds are slowly pre-wetted and/or out-gassed with a first volume of water delivered at a first flow rate. During the extraction phase, a second volume of water is delivered, at a second flow rate, to extract espresso, where the second volume is delivered at a generally greater pressure than the first volume. The second flow rate is greater than the first flow rate. The flow rates, volumes, and pressures are regulated by the espresso machine, which includes a flow rate regulation assembly that comprises first and second flow paths and first and second valves. Baristas may vary the flow rate, volume, and pressure of water throughout the brewing process by opening, closing, or otherwise adjusting at least one of the valves. | 03-05-2015 |
