Title: Apparatus for generating a visual display
Inventor: COWDREY DENNIS ALAN
IPC: G06T15/80
Filed: 1985-02-20
Abstract: A flight simulator has a flight simulation computer 1 to which a computer generated image apparatus is connected to provide a visual display on a CRT display 13 for a trainee pilot. Flight position and attitude data generated by the simulation computer 1 is supplied to the GGI general purpose computer 2. Digital data for surface vertices are stored in a database memory 5 together with codes for overall intensity, texture pattern and surface pane. A surface transformation processor 6 generates a perspective transformation of viewable surface vertices and supplied raster line surface start and end points to a surface frame buffer memory 7. A line processor 8 writes corresponding pixel data into a line buffer memory 9. The intensity data is modulated in an intensity modulator unit 10 before D to A conversion for the CRT display 13. Position and attitude data is supplied by the general purpose computer 2 to a texture generator having an inverse perspective transformation matrix memory 16 for such data, a pipelined inverse perspective transformation processor 17 which utilizes such data and screen pixel coordinates XS and YS to generate texture memory plane coordinates Xe and Ye and a level of detail signal LOD to be applied to address a near texture memory 24 and a far texture memory 28, or a far texture memory 25 alone. Intensity modulation values are thus obtained and supplied to the intensity modulator unit 10 to modulate the pixel intensity data for pixels in textured surfaces. <IMAGE>

Abstract: A gasketed structure for a front opening of a cooker oven comprises an inner member (8) and an outer frame (22) bounding the opening with surfaces of the inner member and outer frame extending behind the opening to define a slit. A widened region of the slit is defined by a portion of the inner surface of the frame member (22) that is offset outwardly of the opening and that is formed to define a concealed slot to which the slit leads. A flanged clip (45) bits into the widened region by insertion of a tongue (49) thereof into the slit and rotation of the clip (45) towards the opening until a web-portion of the clip registers with an outwardly offset portion of the frame member (22). The tongue (49) has then entered the slot and a flange (47), which faces in the same direction as the tongue (49), registers with an exposed face of the outer frame (22). A gasket (51) has a body, portions of which define a longitudinal slit (62) opening to an intended inner face, and has a leg (50) depending from the body. The clip flange (47) enters the slit (62) so that the leg (50) is drawn into the slit between the inner member (8) and the outer frame (22) as the clip (45) is rotated home. The widened regions and clips (45) may occur at radiused corners of a generally rectangular oven opening. <IMAGE>

Title: Joining of pipes
Inventor: CARRUTHERS ALEC
IPC: B29C65/20
Filed: 1987-07-23
Abstract: To join two pipes (1, 2) of heat fusible material, an expansible sleeve (4) slid into one of the pipes (1) until it contacts a heater plate (3) Fig. 1a (not shown) between the adjacent ends of the pipes (1, 2). The heater plate (3) then heats the ends of the pipes (1, 2), and is removed. Then the sleeve (4) is slid so as to overlap the two adjacent ends, and expanded into contact with the inner surfaces of the pipes (1,2). The ends of the pipes (1, 2) are then forced together so that they fuse. The sleeve (4) prevents or limits formation of a bead within the pipes (1, 2) at the join. An outer sleeve may also be provided around the join to limit the formation of an outer bead. The sleeve (4) is preferably a split cylinder expanded by an inflatable bag within the cylinder. Also disclosed is an apparatus for cutting the ends of the pipes prior to joining them. <IMAGE>
