Abstract: A gas stream including the vapor of a solvent is passed through conduit (28) into a reflux heat exchange (40) so as to effect condensation of substantially all the solvent vapor. Cryogenic liquid is introduced through line (70) into condensate of the solvent vapor collecting in bottom section (42) of the condenser to cool the condensate and to stir or agitate it (such agitation preventing local freezing). Chilled solvent condensate is withdrawn from the bottom section (42) and is returned to overhead section (43) of the heat exchanger (40) via a conduit (66) and thus serves as reflux. A further portion of the chilled solvent may be returned to the condensate so as to augment the stirring or agitation of the liquid. Condensate may be withdrawn through the conduit (50) and passed to storage. 
<??>The gas stream may typically be passed first through a water-cooled heat exchanger (13) and then through a heat exchanger (23), cooled by uncondensed gas from the reflux heat exchanger (40), before entering the heat exchanger (40) so as to condense some of the solvent vapor it contains upstream of the heat exchanger (40).

Abstract: A composite metal-plastic gear (20,120) and a method for making the gear disclosed utilize a thin-wall outer metal sleeve (22) into which involute teeth (24) are tool pressed. Thermosetting plastic (32,122) is molded in situ within the sleeve (22) between side walls (26) of the teeth (24) to provide reinforcement. Roll finishing of the sleeve (22) prior to the plastic molding finishes face and flank surfaces (34,36) on the side walls (26) of the teeth (24). Both inward and outward tool pressing of the teeth (24) can be utilized. A metallic central hub (40,124) of the gear (20,120) is positioned within the sleeve (22) prior to the plastic molding. In one gear embodiment (20) the hub (40) is engaged by an end wall (42) of the sleeve (22), while in another gear embodiment (120) the end wall (42) is spaced outwardly from the hub (124). The thermosetting plastic (22,122) adhesively bonds to the toothed sleeve (22) and hub (40,124) and includes carbon fibers that strengthen the plastic and the support provided to the sleeve teeth (24).

Abstract: The control of a quantity (voltage, phase) relating to a generator-motor pair in an electric power station is accomplished by generating a pulse sequence associated to the quantity to be controlled and a predetermined reference pulse sequence and detecting the relative phase shift. This phase shift, or an integrated value of a number of successive phase shifts, controls a double ramp generator the sign and slope of which are proportional to the detected phase shift. After integrating such signal is employed to vary the magnetic induction of the rotor to balance the system again.

Abstract: A thermally powered engine which obtains energy from a closed heat transfer loop. The engine has two power cylinders. A piston is reciprocally mounted within each cylinder and divides the interior space of each cylinder into two portions. A piston rod is affixed to each piston and extends through the upper closed end of each cylinder. A flexible diaphragm is mounted in the lower portion of each cylinder and with the lower closed end of the cylinder forms a power chamber. A fluid fills the upper portion of both cylinders. A passageway between the cylinders permits the fluid to act as a free piston causing the piston of the cylinder in its exhaust stroke to force refrigerant from its power chamber to the condenser of the heat transfer loop. Refrigerant from the evaporator of the transfer loop flowing into a power chamber forces the piston upward during the pistons power stroke. Valves regulate the flow of refrigerant into and out of the power chambers of each of the power cylinders. Flow of refrigerant is controlled so that motion of the pistons of the two power cylinders is 180 DEG  out of phase. Several pairs of power cylinders can be connected in series with the refrigerant flowing through the pairs serially prior to reaching the condenser. Isothermal sequential displacement of the refrigerant through the power chambers of a series of pairs of power cylinders increases the thermal efficiency of the engine.
