Abstract: In railroad applications, a new method of simultaneously lubricating the rail gage side (RAGS) and wheel flanges ahead of a locomotive's tractive wheels and lubricating the top of the rail (TOR) behind the tractive wheels to reduce the resistance of the trailing cars and reduce the locomotive wheel flange wear. The method involves controlling both lubricating units with the same computer controller when a single locomotive is used and two controllers located in two different locomotives in the case of a locomotive consist. The rail gage side lubricant spray is applied on curves of 2 degrees or more only on the high rail. For the top of rail lubrication at the trailing end of the locomotive or locomotive consist this invention requires that the angle of the lubricant jet on the rail from the vertical be between 0 and 80 degrees from the vertical, with the angle increasing in the rear or trailing direction. It further requires that the lubricant jet be a solid jet without breaking into a spray cone.

Abstract: A voltage compensation system for an A.C. power line supplying one or more air conditioners, a telephone system or other telecommunication system, a battery charger, or some other utilization system that should have an input voltage within a given normal range. The voltage compensation system includes a transformer unit containing a transformer having at least two windings coupled electromagnetically by a transformer core; one of those windings preferably is in two segments that are connectable in series or in parallel. One winding is connected to an input terminal and to an output terminal. The other winding adds to the A.C. line voltage when the line voltage drops below a low voltage threshold and/or subtracts from the line voltage when the A.C. line voltage exceeds a high voltage threshold. If the A.C. line voltage is in the range required by the utilization system, the other transformer winding is effectively shorted out or otherwise disconnected.

Abstract: A flush valve includes a body with an inlet, an outlet, a valve seat at the outlet, and a piston movable in the body toward and away from the valve seat to control flow through the outlet. The piston has a chamber and there is a refill orifice in the piston connecting the chamber with the body inlet. Pressure in the chamber maintains the piston closed upon the valve seat. A relief valve in the piston vents the chamber to the outlet to permit the piston to move away from the valve seat to open flow from the inlet to the body outlet. The piston has a guide portion which extends downstream of the valve seat when the piston is in the closed position. The guide portion of the piston has a plurality of outwardly extending axial ribs, the outer surface of which is radially in alignment with the path of flow through said valve seat.

Abstract: A centrifuge (18) is used to introduce a fluid, particularly a viscous fluid such as an encapsulating resin, into a cavity in a container (10), particularly a small cavity such as the inside of an electronic component housing. Measured quantities of the fluid are placed in dispensing vessels (28) in the centrifuge opposite the containers to be filled. The dispensing vessels have openings (36) through which the fluid can flow when centrifugal force is applied. On the application of this force, all the fluid flows out of the vessels into the containers.

Abstract: A faucet spout mounting assembly includes a spout having an elongated tubular portion. There is a spout hub having a cavity, with an end of the spout tubular portion being positioned within the cavity and rotatable relative thereto.
