摘要:
One embodiment of the present invention sets forth an architecture for optimizing graphics rendering efficiency by advancing the Z-test operation prior to pixel shading whenever possible. The current rendering state, as maintained by the setup engine, determines whether advancing the Z-test function above the shader engine for “early” Z-testing is possible or whether the Z-test function should be deferred until after shading operations for “late” Z-testing. Data is dynamically routed to each processing engine in the pipeline, so that the appropriate data flow for either early Z or late Z is dynamically constructed, as determined by the current rendering state. Efficiency is gained by relieving the shader engine of unnecessary work whenever possible by discarding pixels before they enter the shader engine. The same functional units are utilized in both early Z and late Z configurations, minimizing any additional hardware required for implementation.

The presently disclosed subject matter relates to processes that comprise the vacuum extrusion of plant materials. In some embodiments, the plant materials are subjected to a change in pressure of −3 kPa or more. The vacuum extrusion can be used to break open the cell walls of the plant material and of any undesirable micro-organisms associated with the plant material. In some embodiments, the vacuum extrusion can be used as a step in a process for producing ethanol from plant materials, such as from sugar beets. In some embodiments, the vacuum extrusion can be used in a process for providing a desired plant cell-derived molecule, such as a sugar or starch.

A tire carrier assembly includes a rotation shaft and a housing have a bottom wall including a first aperture for receiving the rotation shaft. The housing also includes a sidewall extending upward from the bottom wall defining an interior space. The sidewall includes inner and outer surfaces. A sheave is disposed within the interior space of the housing and has a second aperture that receives the rotation shaft. The sheave also includes a gear member associated with it. Also included is a torque plate having a base, the base having opposing first and second surfaces and a third aperture formed therein. The third aperture has a gear portion formed around a periphery of the aperture. The torque plate also includes an arm portion projecting radially from the base. The gear portion of the torque plate is in operable engagement with the gear member of the sheave. An eccentric bushing having first and second opposing surfaces and an integrally formed bounding wall includes a fourth aperture receiving the rotation shaft. The first surface includes a cam formed thereon. The cam is positioned within the third aperture of the torque arm. A cable guide is positioned within the internal space of the housing and is located radially outboard relative to the sheave for positioning a cable about the sheave. The cable guide includes a lobe formed thereon for contacting a cable. A cover plate having a fifth aperture formed therein receives the rotation shaft. The cover plate is attached to the housing. The tire carrier assembly includes a frangible component that breaks upon the application of a predetermined force allowing the torque plate to freely rotate about the rotation shaft wherein the arm portion of the torque plate engages the inner surface of the sidewall of the housing allowing a controlled payout of cable wound about the sheave.

The apparatus has several carrying bars which can be spread in radial manner from a central headpiece (2) and several shielding screen elements (17, 18), which are in each case fixed between two carrying bars. The multipart construction of the carrying bars from longitudinally displaceable, interengaging bar elements (4, 5) makes it possible to slide screen elements (17, 18) over one another, so that the apparatus, when in use, can provide different shielding surface sizes starting from a compact, slid together and collapsed form. By sliding over one another limited light-transmitting screen elements, it is possible to individually adjust the shielding action.

Eyeglasses which have removable and replaceable lenses to meet individual vision requirements with respect to focal length and strength. In one embodiment, the lenses are slidably and removably mounted to a rod-like holding element. The position of the lenses relative to one another can be changed by sliding the lenses along the holding element. This allows the eyeglasses to accommodate differences in the eye spacing among people. The lenses can also be removed and replaced should an individual desire or need lenses of different focal lengths or strengths.

The soil loosening device has at least one, preferably two journals protruding downwardly from a supporting body, which are driven to a pivotal motion along a limited angle. Tine-like soil loosening tool members in bifurcate arrangement, to be driven along a circle segment, are mounted on the journals. The driving unit for driving the tools is characterized by its simple design since it consists of only a few, reliably guided and sturdy components. Particularly, there is provided a crank shaft which drives a toothed rack member to an oscillating motion. Gear wheels connected to the journals mesh with the toothed rack member. Accordingly the expenditure in manufacturing the device is low and the device has a high resistance to wear. The driving unit of the device may be attached to the supporting body in different angular positions by means of a coupling device.

The invention provides a clothes drying apparatus comprising a plurality of clothes lines or rods to take the clothes to be dried, extending between parallel running supporting arms which are pivotally mounted on an elongate supporting member. It has a wide scope of use and can be stored in the smallest place if not in use. For this purpose, there is provided an elongate central supporting element which is provided at each end with two supporting arms such that two pairs of supporting arms are formed. Each pair of supporting arms is pivotal around the central axis of the elongate supporting element and can be locked in its position. Furthermore, the supporting arms are pivotal by twos around perpendicular axes from an extended position in which they enclose an angle of essentially 90.degree. with the central supporting member, to a closed position in which they run essentially parallel to the central supporting element.

A device for the dosed dispensing of liquid from a storage container through a delivery tube which comes out of a lower pouring chamber. The dispensing takes place upon the second upside down turning of the container. A cup-shaped housing is divided by a transverse wall into an upper chamber and the lower pouring chamber, the pouring chamber and the upper chamber communicating with each other through a flow hole. The transverse wall is traversed by a feed tube which opens above it. Projecting above this is the delivery tube. An air passage extends through the transverse wall. At least three feed tubes are arranged in symmetrical angular distribution with a respective air passage opening arranged between them.

The free-arm shade has radial shade ribs (6), support ribs (7) attached to the latter, and a shade rod slide (8) that is freely attached to support ribs (7). It also has a decentral pole (1) standing outside the shade. One of the shade ribs is vertically displaceably attached to pole (1) by its outer end, and functions as a side arm (2). On its top side, it is connected to pole tip (11) via an articulated rib (4), with this shade rib (2) having a pivot joint (13) between the edge of the shade fabric and the pole. Articulated rib (4) is connected to shade rib (2) via a pivot hinge (12). Shade rib (2) can therefore be pivoted around the axis between pivot joint (13) and pivot hinge (12) so that the entire shade can be tilted sideways in relation to pole (1).
