Abstract: ABSTRACT         Aroma-bearing carbon dioxide gases given off during the processing of coffee, such as the roasting of green coffee, the comminution of freshly roasted coffee beans, or the percolation of roasted coffee, and entrained in a non-condensable gas such as air, are cryogenically condensed to a frost.  Condensation may occur in a liquid nitrogen-cooled scraped-wall heat exchanger from which frost is collected.  The uncondensed gases are vented through a filter member which collects particles of entrained frost.  These particles form a bed of frost that absorbs and/or adsorbs aromas which would normally be lost.

Abstract: A B S T R A C T     Method and apparatus for minimizing or preventing the deleterious skin heating effects associated with conventional short wave diathermy treatment.  The disclosed method includes attenuation of the electrostatic field transmitted by the applicator head and transcutaneous transmission of the radiated electromagnetic energy substantially unimpeded to the deep body tissues to be treated.  The attenuation of the electrostatic field is performed by an electrostatic shield, which is adapted to be positioned on the diathermy applicator head between the radiating electrode and the patient receiving treatment.          However, the radiated electromagnetic field, which is primarily responsible for the therapeutic generation of heat in relatively deep body tissues, passes through the shield substantially unimpeded.  The shield comprises a plurality of narrow, preferably metallic, spaced apart strips and an electrically conductive loop which surrounds the strips and is coplanar therewith.  Each of the strips are oriented generally perpendicular with respect to both the current carrying coils in the applicator head (on which the shield is mounted) and the loop.  The strips extend generally radially outwardly from the loop center area toward the loop, to which each of the strips is electrically connected.  So positioned, the strips impede electrostatic field radiation while facilitating passage of the electromagnetic field.  The loop further reduces electrostatic field radiation by discouraging fringing effects, but its radius is sufficiently large to prevent interference with the radiated magnetic field.
