Abstract: An ironing press includes an ironing table equipped with an endless conveyor belt mounted on two spaced parallel rollers and a drive for rotating one of the rollers to drive the belt. For an ironing operation, a heatable pressing plate is moved near to the ironing table. In order to enable the conveyor belt to have sufficient strength and inextensibility to be driven by the rollers and yet provide a suitable ironing surface the conveyor belt is made up of a drive belt carrying a cushion and a textile covering enclosing the outer surface of the cushion. Friction between the cushion and the covering acts to drive the covering with the drive belt.

Abstract: A domestic electrical food processing appliance has a work bowl supported on a base and a detachable cover fixed on said bowl by a bayonet device. An electrical motor is mounted in the base and drives an output shaft which extends within the bowl and carries a cutting tool. The motor is actuated by depressing a push-button slidably mounted in a boss of the base. A safety bolt is pivotably mounted in the boss and urged into a locking position preventing depression of the push-button. The cover carries an arm which, when the cover is moved to its closed position, pivots the safety bolt out of its locking position to allow depression of the push-button. The engagement of the arm with the safety bolt also prevents removal of the cover from the bowl while the push-button is depressed.

Abstract: The electric cooking appliance has a casing for receiving a removable vessel in which food to be cooked is placed. An electrical heating element is provided in the casing for heating the vessel. The supply of electrical power to the heating element is controlled by a control device including a supply switch and a manually settable control circuit arranged during the normal cooking phase to intermittently place the supply switch in its conducting state so that power is supplied to the heating element intermittently. Prior to the normal cooking phase, the control circuit maintains the supply switch continuously in its conducting state for an initial period of time which is independent of the manual setting of the control circuit.

Abstract: A water heater for a domestic coffee maker comprises a hot plate which is heated by an electrical resistance heater. A cavity is formed within the hot plate. The cavity extends substantially parallel to the top and bottom surfaces of the plate and has a closed end within the plate and an open end in the peripheral surface of the plate. The cavity is divided transversely by a partition which defines together with the internal walls of the cavity, a substantially U-shaped water circulation passage within the cavity. Water flowing through the U-shaped passage is thus heated by the heater.
