5511379 Process for the preservation of products at low temperature in an insulated chamber, installatio April 30, 1996
An insulated chamber (1) for preservation and transportation comprises a container (2) of carbon dioxide snow provided with a lateral opening (5) permitting the injection, within the container, of liquid CO.sub.2 under pressure by a distribution device (10) connected to a source of liqui
4964283 Isothermal container with reservoir for refrigerant and its use for the transportation of fresh October 23, 1990
The present invention relates to an isothermal container with isothermal walls comprising a thermally conducting reservoir (10) for refrigerant product disposed in the upper part of the container; a baffle (3) of thermally insulating material, of a size slightly less than the internal
4934418 Process and equipment for supplying supercritical CO.sub.2 June 19, 1990
A cylinder (11) provided with a plunger tube (28) contains a mass of supercritical CO.sub.2 containing 2 to 6% of dissolved helium, surmounted by a gaseous sky constituted by helium at a pressure higher than about 135 bars. Supercritical CO.sub.2 can be in this way obtained which contain
4924643 Method and apparatus for the treatment of work pieces by shot blasting May 15, 1990
Particles of shot and particles of carbon dioxide ice are simultaneously blasted onto the work piece (6) to be treated. Application in the treatment of the surface of work pieces composed of plastics material or coated with a plastics material.
4878353 Chamber and process for thermal treatment comprising a cooling phase November 7, 1989
A treatment chamber for a charge comprises at least oen door, internal walls delimiting a treatment space, passages for the recirculation of gas, and apparatus for circulating gases in the treatment space and the passages. The circulating apparatus extracts the gases from the treatment
4757691 Cooling process and tunnel July 19, 1988
Liquid carbon dioxide is injected through one end into the upper compartment (14) of the tunnel. The gaseous CO.sub.2 is circulated in the lower compartment (13) partly in a countercurrent manner and partly in a cocurrent manner relative to the objects (22) to be cooled, by a central
4751822 Process and plant for supplying carbon dioxide under high pressure June 21, 1988
A process and apparatus for bringing CO.sub.2 from a storage tank wherein it is stored at a medium pressure and below 0.degree. C. (e.g. -20.degree. C. and 20 bars pressure) to a high pressure such as 80-130 bars, without utilizing any pump operating below 0.degree. C. The build-up of ic
4707951 Installation for the projection of particles of dry ice November 24, 1987
The installation comprises three units separated from one another: a grinding mill (1) fed with pieces of dry ice, a metering device (3) having an extracting spring-screw (13), and a propelling device (5) mounted in a vehicle gas conduit (4). The assembly is maintained under an atmospher
4644754 Process and apparatus for cooling a charge of products February 24, 1987
The apparatus comprises a plurality of modular containers (2) each receiving a charge of products. Liquid CO.sub.2 is injected into each container under the control of a thermostat (28). The excess gases are collected in a single manifold (5), heated in a vessel (3) and then discharg
4615352 Process and apparatus for supplying a mixture of CO.sub.2 and SO.sub.2 or a like mixture under p October 7, 1986
The gaseous CO.sub.2 is supplied at a pressure of 10 bars and at a constant rate of flow to the primary inlet (3) of an aspiration device (1). Gaseous SO.sub.2 coming from a cylinder (24) which is heated and contains liquid SO.sub.2 is conducted through a heated line (4) provided with an
