  • Patent number: 5048401
    Abstract: A barbecue construction using a pair of dual-type truck wheels, one of the pair forming a lower base member and the other of the pair forming an upper firebox member. The lower wheel is disposed on an underlying ground surface with its wheel hub member facing upwardly, and the upper wheel is disposed, in inverted condition, on the lower wheel so that the upper level is supported by its hub member on the hub member of the lower wheel. The aligned axle bores of each wheel are closed to the passage of air therethrough by a plate arrangement that provides a central axis of rotation of the aligned wheels so that rotation of the upper wheel relative to the lower wheel moves the lug bores associated with the upper wheel into and out of alignment with the lug bores associated with the lower wheel and thereby selectively control the upward passage of air therethrough.

  • Patent number: 4714813
    Abstract: A mixer, primarily for thawing frozen biological materials, is adapted to use the turntable mechanism of a microwave oven (33), a container (4, 30) being carried round by the turntable mechanism (34) and being simultaneously rotated about a transverse axis. In one version the container is a cylindrical drum (4) carried by a cradle (3) which replaces the turntable. A transmission (5) such as friction wheels (13, 14) or gears (17, 18; 20) between the drum and fixed structure (17; 19; 22) within the oven causes the drum to rotate about its axis as the cradle is turned. Alternatively, the container (30) is spherical and the turntable (34) tilts so that the container is biassed to one wall (35) of the oven. But rotation of the turntable causes it to co-operate with other walls (37, 38) and thereby generates a tumbling action.
