Abstract: A process for the production of a chimeric antibody, comprising: a) preparing a replicable expression vector including a suitable promoter operably linked to a DNA sequence comprising a first part which encodes at least the variable region of the heavy or light chain of an Ig molecule and a second part which encodes at least part of a second protein; b) if necessary, preparing a replicable expression vector incuding a suitable promoter operably linked to a DNA sequence which encodes at least the variable region of a complementary light or heavy chain respectively of an Ig molecule; c) transforming an immortalized mammalian cell line with the or both prepared vectors; and d) culturing said transformed cell line to produce the chimeric antibody; chimeric antibodies produced by this process; and plasmids and transformed cell lines used in the process.

Abstract: A gaming or amusement machine has a dice or other multi-faceted symbol-carrying body which is in the region of a viewing station of the machine. The body is movable by drive means under the control of control means to present a known selected facet to the viewing station for viewing. One embodiment uses only a single motor and single sensor even though the body is movable about two different axes.

Abstract: A reel for a gaming or amusement machine has a support structure for supporting the reel strip of a significantly lower moment of inertia than a standard reel drum. This is achieved by making the reel strip of stiff material and supporting it only at spaced-apart points, and relying on the strip to support itself between the supported points. The reel support for the strip may be in the form of one or two spiders, each having a plurality of radial spokes. For further support for the strip a ring member may be provided connecting the ends of the spokes. If two such spiders are used, the ring members may be interconnected.

Abstract: In a reel for a fruit machine, a reel has standard symbols or fruit, on which secondary symbols, for example, numbers, are superimposed. The reel has a first, inner strip on which the standard symbols appear, the strip being carried by a reel drum. The secondary symbols appear on a second, outer strip glued to the first strip. The second strip is mostly transparent so that the standard symbols may be viewed with the secondary symbols superimposed on them.

Abstract: A reel for a gaming or amusement machine, of the type commonly known as a fruit machine, has a reel strip which has symbols at least partially within sunken regions of the reel strip. The symbols may be formed in relief in the sunken regions but do not project above a frame which surrounds the sunken regions. The surface of the frame may be arcuate, such that the reel is cylindrical in shape, or flat, such that the reel is polygonal.
