Abstract: A process for manufacturing an object by laser sintering comprises: (i) selecting a powder comprising a polymeric material having a repeat unit of formula —O—Ph—O—Ph—CO—Ph—??I and a repeat unit of formula —O—Ph—Ph—O—Ph—CO—Ph—??II wherein Ph represents a phenylene moiety; and (ii) selectively sintering the powder to produce the object. It is found that the polymer used can be advantageously recycled and blended with virgin material to produce a blend which has very similar mechanical properties and crystallinity compared to the virgin material. Thus, the polymer may be cost-effectively used in laser sintering.

Abstract: The present invention relates generally to a set of synthetic immunointeractive molecules referred to herein as “demibodies” which are useful in targeting particular cells in a subject. More particularly, the present invention provides a set of demibodies wherein at least two molecules from within the set, each specific for a different antigen on a target cell, are required to interact together at the cell surface in order to form an active complex which directs demibody-mediated cellular or complement mediated cytotoxicity and/or reporter function and/or therapeutic activity. The demibodies of the present invention are useful in the targeting of particular cells such as cancer cells including leukemic cells, pathogens including malarial, bacterial and viral agents, and stem cells including embryonic and adult stem cells and pathogen cells. The present invention provides, therefore, methods of treatment, diagnosis and undertaking research and compositions comprising demibodies useful for same.

Abstract: A method and system for performing a recurring lottery sustainable by a sustaining pool is claimed and described. In the method of the present invention, a drawing is held. Winners of the drawing receive a jackpot and are required to transfer part of the jackpot to a sustaining pool. Any given jackpot is drawn partially or entirely from the sustaining pool. The system includes one or more electronic devices and may be used to carry out the method.

Abstract: A computer graphics system includes a plurality of geometry accelerators for processing vertex data representative of graphics primitives and providing rendering data. The system includes a distributor responsive to a stream of vertex data for distributing to the geometry accelerators chunks of the vertex data for processing by the geometry accelerators to provide chunks of rendering data. The distributor generates an end of chunk bit indicative of the end of each of the chunks of vertex data. The system further includes a concentrator for receiving the chunks of rendering data from each of the geometry accelerators and for combining the chunks of rendering data into a stream of rendering data in response to end of chunk bits. The stream of rendering data and the stream of vertex data represent sequences of graphics primitives having the same order. A rasterizer generates pixel data representative of a graphics display in response to the stream of rendering data.
