Abstract: A portable electrical appliance or hand-held blender for processing food. According to the invention, the appliance comprises a case having a handle, the case including an electric motor rotating a first end of a shaft included in a fixed tube, a tool being secured to the shaft, and wherein a removable endpiece secured to the tool is mounted on the second end of the tube. The blender is applicable particularly to catering.

Abstract: Electrical apparatus for thermal processing of food includes a casing which has a transparent portion for viewing the food disposed within the casing. At least one heating element is mounted within the casing for heating the food, the heating element including a heat resistant and mechanically rigid transparent first substrate having a first surface which faces the food and a second opposite facing surface. At least one electrical resistance element is disposed on the second surface, the at least one electrical resistance element being connected to a source of electrical current. At least one second transparent substrate is disposed adjacent the second surface, the at least one second transparent substrate including a transparent infrared reflective coating. Thus, the food disposed within the casing is viewable from the exterior of the casing through at least the first substrate while the food is being heated by the first substrate.

Abstract: An electric locking device includes at least one main switch with a make contact, one secondary magnetic flexible leaf switch with a break contact, at least one auxiliary relay including at least one make contact, and an external control member comprising at least one permanent magnet. The main switch directly controls the relay coil after the secondary switch has been opened by the presence of a magnet in the control member, and the secondary switch, when it closes again, shorts the relay coil. This occurs when the control member and the magnet moves away. The assembly may be constructed such that the approach of the control member, by the presence of the magnet, first causes the opening of the secondary switch, then the closing of the main switch. The control member, during its retraction, releases the main switch that opens before the secondary switch closes.

Abstract: A device controls a switch by means of at least two buttons. The device has at least two buttons acting on levers, each having an end that can bear against the plunger of the switch. The device is particularly applicable to food processors.

Abstract: A device for locking a bowl on a motor support. According to the invention, a latch is hinged to the handle of the bowl and serves to penetrate through a slot into a channel that itself includes a locking surface. The invention is applicable to food processor appliances.

Abstract: An apparatus for extracting juice and pulp from vegetables and fruits is provided having a base containing an electric motor, and a bowl removably attached to the base. The motor has a drive shaft which projects into the interior of the bowl for receiving process tools. The bowl is provided with a strainer which is equipped with a skirt which fits inside the central tube surrounding the drive shaft. The driving shaft has a spindle fitted thereon in two orientations, one in which the strainer remains static during operation and one in which the strainer is driven rotationally when the driving shaft is turning.

Abstract: An auxiliary working bowl for a food processor is mounted without a lid between the top of the sleeve (4) in the main bowl (1) and beneath the lid (2), with a tool (8) fixed to the drive shaft (5) rotating inside the auxiliary bowl (7).

Abstract: A hopper for inserting foodstuffs into a food processor apparatus comprising a base which includes an electric motor whose shaft projects through the surface of the base, a bowl (2) removably mounted on said base, and a cover (1) capable of being locked onto the bowl (2), the cover having an opening surrounded by a chute (3), and a pusher (8) capable of being inserted into the chute (3) in order to press against food, the hopper being characterized in that a pusher support (5) is pivotally mounted at the top of the chute (3), said support slidably receiving a pusher rod (8) terminated by a blade (9) whose section is substantially equal to the inside section of the chute (3).

Abstract: A magnetic safety device, inter alia for a food processor, wherein, when a cover (10) is locked on a bowl (3), which in turn is locked to a base (1), a permanent magnet (12) is brought towards a magnetically controlled working contact (11) connected in series in the supply circuit of a motor (2).

Abstract: An assembly for use with a food processor and adapted to permit processing of large food items, the assembly including a tubular member mountable on the open end of the processor bowl and provided with an inwardly directed wall terminating in a boss.

Abstract: A screw-extruder for shaped food pastes such as spaghetti is removably mounted on a base containing a prime mover. To ensure the safety of the assembly an activator is associated with the cylinder housing the screw and can only actuate a switch in the base when the cylinder is correctly positioned. The actuator may take the form of a manually operable pushbutton on the cylinder, or a lever acted on by the cylinder and acting as a mechanical interlock with a pushbutton and permitting its operation only when predetermined conditions are satisfied. In each case the pushbutton will only act to permit operation of the motor when it is properly positioned relative to a switch in the base.

Abstract: A kitchen apparatus for treating food wherein the rotary tools of the apparatus are stored in the casing which houses the motor of the apparatus and wherein the tools comprise flat disks and are connectable to the shaft of the motor via a carrier.

Abstract: A citrus fruit juicing attachment for an electrically-driven kitchen robot is described. The attachment of the invention comprises an extension piece for fitting on the motor drive shaft, a basket for mounting on the upper bowl of the kitchen robot which is provided at its edge with a projection adapted to operate a motor control switch and at least one cone which can be driven by the extension piece. The cone can only be mounted in the basket when the extension piece is not engaged therein. The need to remove basket and cone when changing cones, thus disenabling the machine, leads to an increase in safety.

Abstract: Snap-on fastener apparatus for removably holding tools on a drive shaft turned by the motor of a household electrical appliance, particularly shown as a food processor with multiple uses, in which interchangeable rotary tools of various shapes and types are employed as a function of the different food preparation tasks to be performed. A protective sheath surrounds the drive shaft and a sheath portion of the tool hub engages upon the sheath of the drive shaft. Fastener apparatus enables the user to affix the desired tool upon the drive shaft sheath in a snap-on manner for removably holding the tool against axial displacement relative to the drive shaft and enables the rapid and convenient installation or removal of the tools without the use of accessories. As the tool is being introduced onto the drive shaft, a flange spreads a plurality of elastic retainer clips which then snap back to reclose over the flange when the tool is fully installed for retaining it in position.
