Abstract: A foodstuff crusher/blender has a hollow body defining a closed elongate cavity. An access device, such as complementary screwthreads on respective ends of two portions of the body, enables the introduction and removal of foodstuff into and from the cavity. A crushing/blending ball is accommodated in the cavity. The cavity is of circular shape along its length in transverse cross-section. One end of the cavity is of substantially part-spherical shape with a diameter not substantially greater than that of the ball. The other end of the cavity is of substantially part-spherical shape with a diameter substantially greater than that of the ball. The diameter of the cavity increases progressively over at least a part of the distance between the two ends of the cavity.

Abstract: A foodstuff crusher/blender comprises a hollow body defining a closed elongate cavity, an access device, such as complementary screwthreads on respective ends of two portions of the body, enabling the introduction and removal of foodstuff into and from the cavity and a crushing/blending ball for accommodation in the cavity. The cavity is of circular shape along its length in transverse cross-section. One end of the cavity is of substantially part-spherical shape with a diameter not substantially greater than that of the ball whilst the other end of the cavity is of substantially part-spherical shape with a diameter substantially greater than that of the ball. The diameter of the cavity increases progressively over at least a part of the distance between the two ends of the cavity.

Abstract: A can opener has two relatively pivotable body portions (1,2), one carrying a rotary cutting wheel (8) and the other a rotary traction wheel (12) having parallel axes, the opener being arranged to receive the rim (R) of a can (C) between the two wheels and to orbit the can as the traction wheel is rotated while the cutting wheel makes a peripheral cut, the traction wheel (12) being shaped to distort the rim during cutting and the cutting wheel (8) having an outwardly angled body portion (10c, 10d), adjacent its cutting tip (10a, 10b), the angled body portion being adapted to contact the outside of the rim below the cut to exert a force in the opposite direction to the traction wheel (12).

Abstract: A food processor has a handle (4) connected to a gear assembly (G1, G2, G3, G4) by which different rotary tools (B) connected to the end (10) of a central shaft (8) in the processor may be rotated (FIG. 3). Different sets of the gears are engaged according to the speed with which the selected tool is to be rotated.

Abstract: A can opener has two relatively pivotable body portions, one carrying a rotary cutting wheel and the other a rotary traction wheel having parallel axes, the opener being arranged to receive the rim of a can between the two wheels and to orbit the can as the traction wheel is rotated while the cutting wheel makes a peripheral cut, the traction wheel being shaped to distort the rim during cutting and the cutting wheel having an outwardly angled body portion, adjacent its cutting tip, then angled body portion being adapted to contact the outside of the rim below the cut to exert a force in the opposite direction to the traction wheel.
