  • Patent number: 4009588
    Abstract: An appliance for making sorbet or ice cream and including means for preventing the mixer blades from becoming locked in the ice by effecting the progressive withdrawal of these blades from a vertical orientation towards a horizontal orientation under the action of the opposing torque applied to the blades by the hardening of the ice during freezing, and an automatic stopping device which is mechanically operable as a result of the withdrawal of the blades or a part associated therewith to break the motor supply circuit when the blades reach their withdrawn position.

  • Patent number: 3955276
    Abstract: Electrically driven device for automatically opening food cans using a serrated wheel to turn the can and a fixed cutting element, consisting of an oscillating arm supporting the spindle of the serrated wheel and controlled in its movement by a cam, with a device for reversing the direction of operation in order to return to the rest position releasing the can after removal of the lid, characterised by the fact that the reversal device consists of a sleeve fixed coaxially on the shaft of the motor, the two ends of which are cones each fitting into a female cone, each female cone being hollowed out of a bevel pinion mounted loose on the shaft of the motor, and the two bevel pinions being meshed permanently with a bevel gear turning at right angles to the shaft of the motor and actuating the serrated wheel driving mechanism, the shaft being given an end play which enables a driving friction to be obtained between either of the conical ends of the sleeve and the enclosing female cone, and thus to reverse at will
