  • Publication number: 20080173660
    Abstract: A device (10) for storing and dispensing endless machining belts for a robotic installation, comprising a support (16) rotating about a vertical axis (14) and having radial arms (12), each equipped with means for locating a machining belt, and means for the stepwise rotation of the rotating support, in order to bring each arm in turn to a station where the belt may be fitted onto a robot arm (40).

  • Patent number: 7319551
    Abstract: An optical device generated by interferometric lithography, in the form of a surface relief pattern that diffracts light, to be used mainly in optical security, produced by optical systems compliant with the Schimpflug and hinge Rules containing: two identical lenses L1 and L2, two physical object location B1 e B2 and one image plane A1?A2. No physical mask is needed throughout the origination process, thus eliminating any kind of border effects. The device actually implements an in-plane focused hologram, with a complex surface pattern of valleys and ridges with a non-trivial generating function, which is, by itself, both an additional security feature of the device and its fingerprint. The time to generate the optical device is proportional to the number of colours specified for the reference geometry and not depend on the overall area of the optical device.

  • Publication number: 20060123830
    Abstract: The present invention relates to a fluid cooling system (1), for use in dispensing or distributing a chilled or cooled fluid, comprising a primary heat exchanger system (2), a secondary heat exchanger system (3), a first conduit (9) through which fluid to be cooled or chilled is circulated, and a heat transfer agent (8) for transferring cooling energy to the fluid to be chilled circulating in the first conduit (9), wherein the primary and secondary heat exchanger systems (2, 3) are arranged at least partially one inside of another. The invention also relates to cooled fluid dispensers incorporating the fluid cooling system and a methods for sterilization thereof.

  • Publication number: 20060049089
    Abstract: The invention relates to a water dispenser 1, for example, but not by way of limitation, of the type comprising a removable carboy 2, mounted on a tapping device (and holder) 3; this carboy supplies water to a tank 4 which is connected to a dispensing faucet 6. An evaporator 5 allows optional cooling of the water upstream of the faucet 6. The invention consists in surrounding a portion (sufficient to obtain the desired effect) of the lateral surface of the tank 4 with a heating device 7, in particular a heating plate that fits against the lateral surface of the tank 4. At regular intervals, the plate 7 heats water in the tank 4 to a temperature and for a period of time sufficient to destroy pathogenic bacteria. This method for disinfection by periodic integral heating of a water circulation and distribution system can be applied to any type of dispenser, of the carboy type, the direct expansion type, or the ice-block type.
