摘要:
A heat exchanger includes an outer tube and an inner tube coaxially arranged within the outer tube. Both of the outer tube and the inner tube include a fluid channel formed therein. A first fluid flows through the fluid channel of the outer tube, and a second fluid, in heat exchange relationship with the first fluid, flows through the fluid channel of the inner tube. At least one heat conductive feature is formed between the outer tube and the inner tube, and on an inner surface of the inner tube to maximize a heat exchange between the fluids.

In order to obtain glass or glass ceramic materials having increased strength, the invention provides a method for producing glass or glass ceramic articles, which comprises the steps: producing an initial glass body (11), mounting the initial glass body (11) on a gas cushion (13) between a levitation support (1) and the initial glass body (11), and at least partially ceramizing the initial glass body (11) on the levitation support (1). The levitation support comprises at least one continuous surface region (3) having at least one gas feed region (151, 152, 153) where levitation gas for the gas cushion (13) is fed out from the levitation support, and at least one gas discharge region (171 172, 173) where gas from the gas cushion (13) is at least partially discharged into the levitation support.
摘要:
A block fitting for coupling tubing segments having a pair of seals, one of the seals being a radial seal and the other seal being an axial seal, wherein the fitting militates against leakage during operation of an air conditioning system upon failure of one of the pair of seals.

摘要:
The method produces a reshaped glass-ceramic article by forced reshaping of a flat green glass part during a ceramicizing process with temporarily lowered viscosity due to crystallization heat. To perform the forced reshaping economically the forced reshaping takes place in a continuous oven for ceramicizing and in an oven section in which the viscosity of the green glass part is temporarily lowered as a result of crystallization heat. An apparatus for performing the process is provided in the continuous oven including different active reshaping devices and/or a hollow mold. The method produces glass-ceramic articles with undamaged surfaces corresponding to surfaces produced during the making of the green glass part (smooth or structured, e.g. knobbed).
