Title: Electronic system generating random lighting effects
Inventor: MALBEC LUDOVIC
IPC: H05B37/02
Filed: 1997-09-10
Abstract: The invention concerns a system for regulating two (or more) electric circuits (1a, 1b) to vary the light intensity of one or several lamps. This is achieved by means of a time switch (4) operating according to a random cycle. Said modulations are of equal duration but create distinct different lighting effects by means of the relay (R1) and the time switch with automatic reset (3). Said modulations start on the basis of an equal cycle repeated several times and shifting in a time interval 'X' to an 'X plus' state (6, 5) after completing the time variable cycle. Said system enables to generate successively connected fading lighting effects, thereby becoming attractive by their dynamics. The invention is applicable to shop windows, frontages, monuments, gardens, green open spaces, urban recreational areas, exhibition stands, shopping arcades, neon lights,...

Title: Bulk freezing of small items of frozen food
Inventor: CLOAREC ALAIN
IPC: A23L3/37
Filed: 1997-05-20
Abstract: The freezing process uses a cryogenic fluid injected into a rotating drum. A jet of liquid carbonic anhydride is injected into the drum parallel to the axis of rotation of the drum, and above the filling level of the drum. Where the drum includes blades (7) to agitate the food being processed (2) the carbonic anhydride is injected into the virtual cylinder (27) defined by the internal radial extremities of the blades. The parameters of the jet are regulated so that the carbonic snow formed is in the bottom of the drum, opposite the injection point. This process produces a protective ice layer over the product.

Title: Machine for automatically packaging batches of bread
Inventor: ENOS JACKY
IPC: B65B57/14
Filed: 1997-06-13
Abstract: The machine has a packaging station equipped with packaging elements (16,83,86) to place a batch of loaves of bread into a container such as a box or bag. A horizontal feed conveyor (3) includes a metal detector (4) an ejectors (6,1) for loaves that are detected to contain metal. A transfer conveyor (7) moves the remaining loaves towards the packaging station.

A box supply conveyor is used to transport the open boxes or bags from a stack where they are stored in flat form and assembled. The boxes or bags are then sealed after they have been filled with a batch of loaves. These assembly and sealing operations take place either side of the packing station. An evacuation conveyor then removes the filled boxes.
