Abstract: An air-distributing system including a compressor for supplying compressed air to an outlet connected to a distributing conduit includes a condensing mechanism between the compressor and the distributing conduit for removing moisture from the compressed air. The condensing mechanism consists of an elongated chamber that has an inlet and an outlet adjacent the upper end with a tube extending from the inlet below the outlet and having a throttling valve at the lower end which produces expansion of the compressed air resulting in cooling within a condensing can where the cooling results in condensation on the surface of the condenser. The air flow is reversed by a funnel arrangement at the lower end of the condenser can and flows past the tube having the incoming, hotter compressed air to withdraw heat therefrom before entering into the distributing conduit.

Abstract: A permanent pier piling for use in docks and the like in a body of water whereby an antifreeze solution within the piling circulates to distribute latent ground heat from the lower portion of the piling to the upper portion of the piling to maintain a fluid interface between the piling and the ice during the winter season.

Abstract: An apparatus disposed in a speedometer-odometer drive assembly for transferring and translating the rotation of a speedometer drive cable to a speedometer needle registering speed and an odometer registering distance, having a field cup disposed at one end of a drive shaft in communication with the speedometer cable and rotatable about a central axis with this shaft. The rim of the field cup is discontinuous at at least one point about its periphery by virtue of a cut or split being upset with respect to the radial plane of the surface of the field cup rim. These cut or split edges of the field cup rim act to engage successive threads or teeth on a gear means driving the odometer as the field cup rotates. A flux cup is inserted into the field cup to cover a magnet mounted within the field cup. The flux cup responds to the magnetic field created by the rotating magnet, thereby driving said speedometer. The gear means driving the odometer comprise a camming means fixedly mounted on a face gear.
