104results about How to "Uniform extraction" patented technology

An illumination system includes a light guide for distributing light. Extraction structures are provided to uniformly extract light from the light guide. The structures extract more light out of the light guide when light is propagating in the light guide in a direction toward the light input area than when light is propagating in the light guide in a direction away from the light input area.

The invention relations to a portion capsule for producing a beverage, having a substantially truncated cone-shaped or cylindrical base element (2) that has a hollow space (3) and a membrane (4) sealing the hollow space, wherein within the hollow space a filter element (5) is disposed, which subdivides the hollow space into a first region (6) for receiving a raw beverage material and into a second region (7) for receiving a beverage extract, wherein the filter element is fastened to the base element by means of at least one fastening means (8) that is arranged substantially in the region of a face of the base element lying opposite the membrane.

A method of brewing a beverage, such as freshly brewed coffee, in an electrical, automatic beverage brewer (10) with a rotatable mixing chamber (12) for mixing water (109) from a hot water tank (28) with dry beverage ingredient (108) having a closed top (7) and an open bottom (3, 66) to which is releasably mounted a brew basket (14) with an open top (19) for fluid communication with the mixing chamber (12) through the open bottom (3, 66). Before mounting, the brew basket (14) is loaded with a filter (105) and dry beverage ingredient (109). The mixing chamber (12) with the brew basket (14) attached is then automatically turned upside down (FIG. 6) to dump the dry beverage ingredient (109) out of the filter (105) and onto the closed top (7) of the rotatable mixing chamber (12). A preselected amount of water (109) is then infused into the mixing chamber (12) to a level beneath the open bottom (3) and filter (105) and onto the dry beverage ingredient (109) for mixing therewith. After a preselected mixing time period is passed the mixing chamber (12) and mounted brew basket (14) is automatically turned right side up to pass the beverage (110) through the filter (105) and out of the drain hole (90) of the brew basket (14). After the mixing chamber (12) has been returned to an upright position, pressurized air (44, 46, and 48) is automatically injected into the mixing chamber (12) to hasten the passage of beverage (110) through the filter (105) and out of the drain hole (90).

The present invention discloses a process for extracting ginkgo biloba flavone, ginkgo biloba lactone and ginkgo biloba phenolic acid from ginkgo biloba leaves. The process comprises the following steps: (1) carrying out a pretreatment on ginkgo biloba leaves; (2) carrying out extraction by an ultrasonic device; (3) carrying out reduced pressure concentration; (4) loading the resulting solution on a macroporous resin to carry out a treatment; (5) collecting the resulting eluate; (6) carrying out reduced pressure concentration; (7) detecting the resulting extract; and (8) carrying out drying and storing on the extract. With the process of the present invention, the ginkgo biloba flavone content and the ginkgo biloba lactone content in the extract prepared by the process of the present invention are high, the loss of active ingredients are avoided, the production process is simplified, the production cycle is shortened, and the ginkgo biloba phenolic acid content after treatment is substantially reduced.
