Abstract: Precooked dishes loaded in a refrigerated enclosure (4) of a transport cart (1) for their transport toward a place of consumption, are selectively restored in temperature. The refrigerated cooked dishes which must be restored in temperature are, before being loaded in a single enclosure (4), disposed with the dishes not requiring restoration of temperature, on a same tray (6) common to all the dishes constituting an individual meal. Each tray is disposed directly on a heating plate inside the single enclosure (4) of said refrigerated transport cart, and the restoration of temperature of only the first-mentioned dish or dishes is effected by heat transfer through a thermally conductive region of the common tray (6) underlying only the first-mentioned dish or dishes.

Abstract: Device for induction heating of cooking receptacles, of the type comprising at least two concentric induction coils supplied by a generator. Each induction coil (I.sub.1, I.sub.2, I.sub.3) is supplied by a separate generator (G.sub.1, G.sub.2, G.sub.3), the number of induction coils being equal to the number of supply generators. A control block (8) effects the independent operation of each supply generator (G.sub.1, G.sub.2, G.sub.3). The control block (8) is adapted to cause to operate according to a sequential order the supply generators (G.sub.1, G.sub.2, G.sub.3) during a detection step of the presence of a load on the corresponding induction coil (I.sub.1, I.sub.2, I.sub.3), starting with the generator (G.sub.1) corresponding to the innermost concentric induction coil (I.sub.1) and progressing to the outermost concentric induction coil covered by the receptacle (9) to be heated. The supply generators (G.sub.1, G.sub.2, G.sub.

Abstract: A connection device for two successive segments (1A, 1B) of a tunnel oven for cooking food, comprises a first sleeve (16A) fixed to the frame (18) of the tunnel and second sleeve (17) secured to the tunnel segments (1A, 1B). The second sleeve (17) is mounted axially slidable relative to the first sleeve (16A). Seals (25) are disposed between the first and second sleeves, within the thickness of these latter, so as to permit sliding without loss of sealing. The device also comprises, in series, a quarter wave trap (26) and a body (31) that absorbs microwaves, also disposed within the thickness of the device.

Abstract: The tunnel oven comprises an elongated enclosure connected to an inlet closure and an outlet closure and traversed by a conveyor transporting the food to be cooked. The enclosure is delimited by a wall forming a floor, a wall forming a ceiling, and two side walls of which one is provided with a door giving access to the interior of the enclosure. The enclosure is divided into several successive cooking chambers separated from each other in the upper portion of the latter, each chamber being associated with several different heaters, including microwave heaters. The microwave heaters of each chamber comprise several sources provided with microwave emission members disposed in the wall forming the ceiling of the chamber such that one microwave emission member will be offset relative to a neighboring microwave emission member, in the direction of advance of the food.

Abstract: A shelving system with removable shelves (13) comprises pairs (1) of uprights (2) that are interconnected by cross-bars (3). It is characterized in that the uprights (2) of a pair (1) are provided on their facing faces (4) with regularly spaced apart pegs (6) on which riders (8) are placed, which riders can be removed only by being lifted. The riders (8) are each provided with one or two lateral fastening lugs (9) projecting beyond the footprint of the pair (1) of uprights (2) and co-operating with respective recesses (15) situated in each of the corners (14) of each shelf (13) to support said shelf (13). The shelves are easily installed and removed without tools and cleaning is easy.

Abstract: A food container comprises a bottom (3) which is substantially rectangular and which has outwardly flared walls (4) rising therefrom and terminating in a substantially rectangular opening (7). The tops of the walls are outwardly surrounded by a horizontal rim (5) which is rectangular in shape and they are capped by a vertical rib (6) extending above the rim (5). The container has a cover (2) having a horizontal rim (8) and a vertical rib (9) extending downwardly therefrom suitable for engaging around the vertical rib (6) of the container (1). The vertical ribs (6, 9) being of substantially the same height on the container (1) and the cover (2). The vertical rib (6) on the container (1) is provided with notches (12) on at least two sides thereof, and the vertical rib (9) of the cover is provided with outwardly offset lengths (16) of reduced height disposed opposite the notches (12) in one position of the cover ( 2) and not disposed opposite the notches (12) in a second position of the cover (2).

Abstract: A food container comprises a bottom (3) which is substantially rectangular and which has outwardly flared walls (4) rising therefrom and terminating in a substantially rectangular opening (7). The tops of the walls are outwardly surrounded by a horizontal rim (5) which is rectangular in shape and they are capped by a vertical rib (6) extending above the rim (5). The container has a cover (2) having a horizontal rim (8) and a vertical rib (9) extending downwardly therefrom suitable for engaging around the vertical rib (6) of the container (1). The vertical ribs (6, 9) being of substantially the same height on the container (1) and the cover (2). The cover rib (9) has a plurality of shoulders (16) near the top thereof for co-operating with the container rib (6), and enabling an upper position and a lower position to be defined for the cover (2) on the container (1).

Abstract: A cover (1) for a standard container (2), has a substantially rectangular bottom (3) and a substantially rectangular opening (4) at the top. The cover (1) includes lower rib portions (6) which are disposed in a substantially rectangular configuration with rounded corners which fit into the opening (4) of the container (2) and upper rib portions (8) which are disposed in a rectangular configuration dimensioned almost similar to those of the set of lower rib portions (6). The rib portions (6,8) are separated by gaps (7,9) which allow easy washing, and the gaps (7) of one set of rib portions (6) are not adjacent to the gaps (9) of the other set of rib portions (8). To make it easier to grip the cover (1), a portion of its edge is raised to form a handle (10) adjacent to a rib portion (8) of the upper set. Stacking of containers on covers and stacking of covers one on another is thereby greatly facilitated.

Abstract: In a conveyor plant for equipping both sides of a wall or partition in which two spaced apertures are formed to permit the free passage of the movable component elements of the conveyor plant, a pair of casings are each adapted to be clamped by means of jaws against one of the adjacent vertical edges of the aperture; a pair of flat longitudinal members are disposed against the wall and secured to the two casings at their ends, and a safety device responsive to any interference with said apertures is provided for actuating the knock-off motion of the plant by means of microswitches responsive to the movements of a flexible blade in one or the other direction.
