Abstract: A two-stage combination reciprocating and bladder pump wherein a hollow piston is disposed for reciprocating movement within a main pump body, and a bladder pump is housed in the piston. The piston pump and bladder pump are thus coaxially arranged, with the bladder pump mounted within the piston pump and operably cooperating therewith. A reciprocating tube is attached to the piston to permit operation thereof from above ground, and also serves as a conduit for alternately supplying pressurized air and atmospheric venting to the bladder pump. A rigid support pipe supports the main pump body, and has the reciprocating tube extending coaxially therethrough. A fluid discharge tube is in turn coaxially arranged within the reciprocating tube, thus defining a triaxial tubular arrangement. The fluid discharge tube provides communication between a fluid chamber of the piston pump and a fluid chamber of the bladder pump, and also functions as a conduit for discharging fluid to the exterior of the main pump body.

Abstract: A bladder pump is suspended in a tubular air lift pump housing which is closed at its lower end by a check valve, and which is connected at its upper end by a first conduit and a separator selectively to a supply of air under pressure. Two additional conduits extend from the upper end of the bladder pump in either side-by-side relation, or coaxially one within the other, through the bore in the left pump housing and first conduit and the separator to control means. A first one of the two additional conduits is secured in the upper end of the bladder pump to communicate with an upper check valve chamber, which is connected by a perforated discharge tube to a lower check valve chamber in the bladder pump. The discharge tube is surrounded by a flexible bladder, which is separated from the bladder pump housing by an air chamber which communicates with the other of the two additional conduits to the control means.

Abstract: A technique for condensation soldering of articles (29) in a facility (40 or 80) having a vapor chamber (42) and a pair of aligned input (102) and exit (104) throats. An article (29) to be soldered is transported sequentially through the input channel (56), the vapor chamber (42) and the output channel (58). Simultaneously, air is moved, in a controlled manner, into and through a portion of the exit channel, in a direction opposite to the movement of the article and withdrawn from the input channel. The air exiting the input channel is processed to recover the expensive vapor entrained therein.
