Abstract: A heat extraction or reclamation system particularly adapted to recover otherwise rejected heat from the refrigerant gas flowing through air conditioning and refrigerating systems includes a counter-flow heat exchanger for transferring heat to a medium such as water, the heat exchanger being installed in the tubing upstream of the conventional condenser. The heat extraction system has a pump for circulating water or other medium to be heated, located on one side of the heat exchanger. Hot refrigerant gas, the so-called superheated gas flowing from the compressor of the air conditioning or refrigerating system, is circulated through the other side of the heat exchanger. The pump flow rate and the heat transfer area between the refrigerant gas and the water or other medium are chosen to ensure that the refrigerant gas outlet quality remains within limits which ensure flow continuity in operation. Refrigerant gas leaving the system will contain some liquid in the form of droplets or a small stream. The water temperature is maintained within limits by stopping the pump when the inlet water temperature reaches a predetermined maximum value. Refrigerant velocity through the heat exchanger is reduced compared to velocity at compressor discharge in some embodiments to lengthen residence time in the heat exchanger sufficiently to increase heat transfer from the refrigerant gas and yet provide an excess quantity of heat in the refrigerant gas compared to the heat removal capacity of the flowing water.

Abstract: A glass optical waveguide filament preform is prepared by chemical reaction of vapor ingredients within a glass substrate tube. As the reactants flow through the substrate tube 52, a hot zone 54 traverses the tube to cause the deposition of sooty reaction products 44' in the region of the hot zone, the soot being consolidated to glass layer 48'. A baffle tube 50 extends into that end of the substrate tube into which the reactants flow. The baffle tube 50, which traverses the substrate tube along with the burner 56, ends just short of the hot zone 54 so that no soot is deposited thereon. A gas flowing from the baffle tube creates a gaseous body or mandrel 66 which confines the flow of reactant vapors to an annular channel adjacent the substrate tube wall 52 in the hot zone, thereby increasing deposition rate and efficiency. <IMAGE>

Abstract: An object is produced from a tubular blank (10,15,17) of thermoplastic material of polyester or polyamide, preferably of polyethylene terephthalate by reducing the thickness of amorphous material in one or several areas of the blank by means of one or several consecutive re-shaping operations. A mechanical shaping device (23,29,71,81) moves a transitional zone (13,14,113) situated between thicker and thinner material along the blank and simultaneously elongates the blank in the moving direction of the transitional zone while reducing the thickness. After the last re-shaping operation the thinner material preferably has an oriented state. During the re-shaping operation the temperature of the material in the transitional zone (13,14,113) is controlled at a level which, immediately before the re-shaping operation, is within or close to the range of the glass transition temperature (TG). In one embodiment the reduction of the wall thickness of the material is begun in a track (12) in the wall of the blank and continues symmetrically around the track. Clamping devices (41,51,61) are used to maintain the axial position of the blank. The blank is suitable for re-shaping, for instance, into a container in which the mouth also consists of oriented material.

Abstract: An identification card equipped with an integrated circuit, in which the circuit along with its connection leads is arranged on a carrier element which is embeddedly enclosed by the card on all sides by use of the hot lamination technique. In order to protect the sensitive arrangement, the carrier element is subjected to the full laminating pressure only when one or more layers in the card construction have softened. This is achieved, for example, by providing buffer zones in the card laminate at least in the area of the arrangement in the form of cavities or layers that are easy to deform elastically. The buffer zones protect the arrangement from local pressure peaks in the initial phase of the laminating process. It is also possible to control the laminating pressure as a function of the temperature or the degree of softening of the card layers.
