Title: Feed hopper for providing an extruder with a plurality of components containing material to be extruded
Inventor: NEUMANN ULRICH
IPC: B01F25/90
Filed: 1991-08-02
Abstract: The invention relates to a feed apparatus for the material to be fed to an extruder 14. Apart from a main component, the extruder 14 is fed at least one secondary component, which is to be mixed with the main component and the material throughput of which is set as a function of the consumption of the extruder 14, determined on the basis of the material throughput of the main component. The feeding of the main component takes place via a central shaft 6 into an inlet nozzle 10, into which the discharged material stream is directed with a radial flow component by means of a directing element 8. This material stream is crossed by the material stream of the secondary component, introduced above the outlet 7 of the central shaft 6 into the inlet nozzle with a downwardly directed flow component. The secondary component is incorporated in the material stream of the main component without any back pressure, so that no back pressure of the secondary components occurs. As a result, the material throughput of the main component is reduced to correspond to the material throughput of the secondary components.

Abstract: A solar heat collector roof comprises an absorber plate (1) for incident radiation energy and a heat exchange plate (2) placed directly thereunder. The heat exchange plate is corrugated in such a manner that it comprises channels extending down along the roof. The heat exchange plate (2) is moreover in direct contact with the absorber plate (1) thereabove. A heat carrying or heat removing liquid medium (3), e.g. water, flows in the channels. The liquid medium (3), which removes heat from the heat exchange plate (2), is supplied at such a rate that the flow rate down along the roof in the channels lies below the rate at which the surface tension of the heat carrying medium (3) is broken, so that a winding and travelling flow pattern is imparted thereby to the liquid medium (3), and up along the channel walls (4).

Abstract: A method for identifying a chemical that acts as an agonist for a G-protein coupled cell surface (GPC) receptor. The method comprises introducing to test cells of a pigment cell line capable of dispersing or aggregating their pigment in response to a specific stimulus and expressing an exogenous clone coding for the GPC receptor, a stimulant that sets an initial state of pigment disposition wherein the pigment is aggregated within the test cells if activation of the exogenous GPC receptor induces pigment dispersion, or introducing a stimulant that sets an initial state of pigment disposition wherein the pigment is dispersed within the test cells if activation of the exogenous GPC receptor induces pigment aggregation; contacting the test cells set in an initial state of pigment disposition with the test chemical; and determining whether the pigment disposition in the test cells treated with the chemical is changed from the initial state of pigment disposition, wherein a change in pigment disposition observed in the test cells expressing the exogenous GPC receptor indicates that the chemical is an agonist for the exogenous GPC receptor.

Abstract: A paper feeding device, used in a copier, has a swivel cassette (32) capable of turning to a longitudinal feed position for longitudinal paper feed and to a lateral feed position for lateral paper feed. The paper feeding device is so arranged that the swivel cassette is automatically turned to a priority-given position when power is turned on, auto clear is executed or an all clear key is depressed. The paper feeding device has a memory (53) for storing the number of sheets supplied from a respective one of the feed positions of the swivel cassette. A paper feed position used high frequency is regarded as the priority-given position by comparing the stored numbers with each other by controller (51). The controller controls a motor driver (52) of a swivel cassette turning mortor (36) so that the swivel cassette is set to the paper feed position used high frequency when power is turned on, auto clear is executed or the all clear key is depressed. Accordingly, the user can save the trouble of changing over to that feed position used with high frequency, and this feature improves the convenience of the copier.
