Title: Sheet carrier for tractor-feed printers
Inventor: WESTON COLIN KEITH
IPC: B41J11/00
Filed: 1984-07-09
Abstract: Prior art methods of transporting sheets of paper such as letterhead sheets through tractor- feed printers have included the use of glue, and of vacuum, to hold the sheet onto a carrier 3. (The carrier has a series of holes along each of its edges characteristic of the tractor-feed system.) Pockets formed by folding the carrier have also been proposed. Disclosed is an improved carrier where the pockets 15 are formed simply and inexpensively by a double thickness band (4), caused either by the overlapping of pieces of the carrier, Fig. 2 (not shown) or by separate pieces 5. This manner of forming the pockets (15); lends itself to the provision of an endless-loop type of carrier, since the final joint between pieces can be made after the carrier has been fed through the tractor rollers of a tractor-feed printer. The pieces of the carrier may be plastic or paper and may be disposable after use or re-usable depending on the type of adhesive used. <IMAGE>

Title: Method and apparatus for the production of video signals representing background textures
Inventor: VOET EDUARD
IPC: G09G1/16
Filed: 1984-09-25
Abstract: Video signals for the representation of textures on a display generated digitally and in real time. From a sequence of pseudo-random digital words stored at 92 and read out under control of timing pulses beginning at a prestated start word. The pattern is repeated along a line by reselecting the same start word. Subsequently generated lines may be the same (so as to extend the pattern in the vertical direction) or another start word. Filtering is provided between vertically adjacent pixel values. For a black and white image it is sufficient to interrogate only one position of each word. <IMAGE>

Title: Centrifugal pump impellers
Inventor: LOXLEY RUSSELL ALLAN
IPC: F04D29/24
Filed: 1984-12-22
Abstract: A rotary impeller (200) for a centrifugal pump is capable of efficiently pumping fluids comprising mixed gaseous, vapour and liquid components, e.g. aviation fuel (204) with air and vapour bubbles (202) in it caused by low pressures in the fuel line. Approximately aerofoil-shaped impeller blades (208) define unconventionally shaped passages (206) between them, the passages being provided at their inlets with guide blades (210) which intercept the fluid flow coming from the eye of the impeller, separate out the gaseous or vapour components, and form the liquid component into a high-velocity jet sheet (214) which is projected down the passage through the separated gaseous component towards the outlet of the passage, where it collides with a liquid/gas interface (215) at the point where conventional centrifugal pumping takes over in the divergent outlet portions of the passages. The liquid jet sheet (214) entrains the collected gaseous and vapour components and the turbulence caused by the jet sheet's collision with the interface (215) causes rapid remixing of the gaseous and liquid components, whereupon the gaseous component is redissolved in the liquid component due to the pressure rise across the pump. In an alternative embodiment (Figure 3, not shown) the guide blades become suitably oriented inlet guide faces of the impeller blades. <IMAGE>
