Abstract: A compact desiccant-operated air dryer includes air directing housings, each housing including a separate desiccant bed. Each housing includes an associated desiccant bed to provide dehumidification to process air flow during a dehumidification phase of the housing; during operation, at least one desiccant housing will be in the dehumidification phase so as to provide continuous dehumidification. The associated desiccant bed for a desiccant housing is reactivated during the reactivation phase of the desiccant housing. Each desiccant housing extends between two external chambers at each end; a process inlet chamber and reactivation outlet chamber at one end, and a process outlet chamber and a reactivation inlet chamber at the other end. Each housing is connected to the two chambers at each end by a distinct associated inlet or outlet.

Abstract: The apparatus relates to a jet pump or apparatus which displaces a main fluid by a pressurized driving liquid. The apparatus has a duct to receive the main fluid, and a driving liquid manifold cooperating with the duct to receive the pressurized driving liquid. First and second sets of inwardly facing jet nozzles are disposed adjacent a transverse plane of the duct and penetrate the duct side walll to pass the driving liquid into the duct at a mixing portion of the duct having a constant cross-sectional area. The first and second sets of jet nozzles are inclined at angles to the duct axis so that the first nozzles are inclined at a greater angle than the second nozzles. Efficiency of the pump is improved by admitting pressurized gas into the duct and providing the pump with a diverging outlet portion to act as diffuser.

Abstract: A novel apparatus for semi-automatically baiting the hooks of long-line used in commercial deep sea fishing. The apparatus includes a bait holding receptacle, a slotted separator positioned in or in association with the receptacle and extending from substantially end to end thereof, whereby ground-line with leader periodically attached to the ground-line is passed behind the separator such that a gangion portion of the leader extends through the slot in the separator and the hook of the leader secures itself to a piece of bait held in the bait holding receptacle.
