The present invention provides processes for the extrusion of a shapeable resin-containing composition as a foam, wherein said composition comprises at least one extrudable resin and at least one saccharide ester of Formula I: wherein “A” is independently hydrogen or has the structure of Structure I: wherein each “R” is independently an aliphatic or aromatic moiety of about 8 to about 40 carbon atoms, and wherein all of the “A” moieties of at least about 70 wt. % of the compounds of Formula I comprise moieties of Structure I. Also disclosed are foams produced by said processes.

In an image processing system for providing two-dimensional pixel images comprised of a purality of polygonal image primitives and a background, the polygonal image primitives representing a three-dimensional object, a Z buffer and a color buffer are cleared by the steps of rendering image primitives relating to foreground in the color buffer (354) and the Z buffer (353); and subsequently scanning the Z buffer and for each pixel, if the Z value is a predetermined background value such as zero (357), clearing the corresponding location in the color buffer to background color (358), and if the Z value is not the predetermined background value, clearing the Z buffer to that predetermined background value (359). In the method, either a Z buffer or a color value is written during the buffer clearing process, but never both. The pixels may be read from cache in groups, the size of a group being selected to maximize the possibility of all consecutive pixels in a group being either foreground or background pixels. Further bandwidth saving may be achieved by the use of a tile buffer and two output buffers.

An abrasive grain comprising about 20 to about 50% by weight of zirconia; reduced titania in an amount on analysis expressed as titanium dioxide of 1.5 to about 10% by weight; total carbon in an amount of 0.03 to about 0.5% by weight; impurities, if any, in a total amount on analysis expressed as the oxides of not greater than 3% by weight; and a balance of alumina. The microstructure of the abrasive grain comprises primary alumina or zirconia crystals embedded in a supporting alumina-zirconia eutectic matrix. The grain may be produced by combining and melting the alumina and zirconia; adding titania and carbon (excess carbon being required); melting and reducing the titania under reducing furnace conditions; and solidifying the melt in under three minutes by means of a suitable heat sink material. The abrasive grain has a high proportion of tetragonal zirconia and may be used to produce coated abrasive products or bonded abrasive products.

The present invention pertains to the field of control and manipulation of a digital audio signal by a user manipulable touch sensitive control surface. The present invention is specifically applicable to user manipulation of digital audio signals by disc jockeys (DJs).A touch sensitive surface substantially circumferential in shape is divided into two regions: an inner or central portion and an outer or circumferential portion. The inner portion responds to linear motion imparted by the user while the outer portion responds to circumferential motion. The linear motion imparted by the user in the central portion is used manipulate a digital audio data stream in order to impart a scratch effect.

An emergency floatation system associated with a landing gear of a rotorcraft comprising at least a float unit and a raft module. The float unit is formed by a base and a float cover with an inflatable float being positioned therebetween. The raft module is formed with a raft compartment adapted to receive an inflatable raft in the packed condition thereof. The raft module is supported on the float by the base. The raft is adapted for inflation and deployment from the raft module independently of the float deployment.
摘要:
A technique for encoding pixel color values for a full or partial digital video image frame has each different color within the image being assigned a color value. The most common one of the colors (0) within the frame or frame segment is identified, and runs of at least three successive pixels of that predominant color are encoded as a first code (00) indicating a run and a second code indicating the run length (LL). Runs of successive pixels having a color (1, 2, 3) other than the predominant color (0) are encoded as successive iterations of a code containing only the respective color value when the run length is less than or equal to a threshold value and as a first code indicating a run (00), a second code indicating a run length (LL), and a third code (CC) identifying the color value when the threshold value is exceeded.
