Abstract: A work machine in which an engine and a reserving unit configured to reserve lubricating oil to be supplied to the engine are connected by a lubricating oil channel, and the lubricating oil is circulated, wherein at least a part of the lubricating oil channel and at least a part of a working fluid channel for a working fluid to be supplied to a work unit of the work machine are arranged such that heat can be exchanged between the lubricating oil and the working fluid.

Abstract: A waveguide flange system connects a pair of microwave components each having a flange attached thereto. Each flange includes a waveguide central bore, a knife edge surrounding the central bore on one side of the flange, and a weld plate extending orthogonal to the central bore in all directions. A deformable gasket is placed between the two flanges and engages the knife edges. A waveguide clamp assembly applies a uniform compressive force to clamp the flanges together to deform the gasket and to form the RF seals. The weld flanges are tack welded, the clamp removed, and the weld completed to form the vacuum seal. A venting trough through the knife edges provides a path for gasses from the region between the weld and the knife edge to vent to the central bore. The clamp may optionally be replaced after the welding for added strength and protection.

Abstract: A nozzle body may be provided. The nozzle body may comprise a flow path and a vent. The flow path may be configured to provide an open channel for a fluid between a lower portion of a pipe and at least one outlet. The vent may be configured to vent a gas in an upper portion of the pipe to the flow path.

Abstract: A self-propelled irrigation system has an elongated pipeline supported above a field by a plurality of drive towers. The drive towers each have a base beam assembly, a tower structure extending above the base beam assembly for supporting the elongated pipeline, and a plurality of drive wheel assemblies for moving the base beam assembly over a field. The drive assemblies include first and second drive assemblies mounted to respective ends of the base beam assembly. At least one of the drive towers also has a third drive assembly mounted to the base beam assembly between the first and second drive assemblies. The base beam assembly supporting the third drive assembly is articulated between its first and second ends and pivotally connected to the lower ends of the tower structure to allow the third drive assembly to move vertically relative to the first and second drive assemblies when traversing uneven terrain.

Abstract: A hydraulic circuit and a wheeled self-propelled moveable frame provides a one-way feed of water under pressure selectively bearing a liquid soap or a liquid rinse chemical via a wind up hose mounted on a spool via a drive motor to axle to belt to clutch to shaft on the moveable frame through a multi-way directional valve to a water powered drive motor for driving the moveable frame forward and reverse relative to an open end of a vehicle body and said spool. A water cylinder changes the angle of inclination of a floor nozzle tube rotatable about its axis horizontally at the front of the moveable frame and bears a series of longitudinally spaced nozzles, when the machine travel reverses towards the open end of the vehicle body. The multi-way directional valve changes the water flow direction upon impact of a sensor operatively coupled thereto and projecting forwardly of the front of the wheeled self-propelled moveable frame.
