A sliding component and its producing method are provided. The sliding component includes a base section made of steel or cast iron, and a sliding section having a sliding surface, made of copper alloy including hard particles, and joined to the base section. The hard particles in the sliding section are arranged such that those in a region including an outer periphery of the interface with the base section have their longitudinal directions coinciding with the directions along the outer periphery as compared to those in an inner peripheral side. This improves the durability of the sliding section in its region including the outer periphery of the interface with the base section.

In accordance with at least one aspect of this disclosure, a system (e.g., for aircraft systems) includes an actuator cylinder. The actuator cylinder comprises, a composite cylinder body, the composite cylinder body being axi-symmetric across at least a longitudinal axis. In embodiments, the composite cylinder body can include, a first plurality of plies laid in a first direction relative to the longitudinal axis and second plurality of plies laid in a second direction relative to the longitudinal axis different from the first direction to form a hollow chamber. The actuator cylinder can include a first metallic reinforcing ring and a second metallic reinforcing ring disposed at respective axial ends of the cylinder body configured to anchor the first plurality of plies and provide an axial reaction under axial stress and configured to provide load transfer from the cylinder body to one or more adjacent actuator components.

A liquid droplet catching device installed in a compressor impeller, the device includes an aperture disposed on a surface of the impeller and configured to receive the liquid droplet, and a channel disposed beneath and in fluid communication with the aperture, wherein in the channel is configured to direct the liquid droplet away from the aperture and out of the compressor impeller.

An agricultural machine or implement has a main frame section and at least one wing section, each having lift cylinders. A main shank frame may be pivotally attached to the main frame section and may have hydraulically adjustable gauge wheels. Wing shank frames may be pivotally attached to the wing sections and may also have hydraulically adjustable gauge wheels. Bypass circuits may be used to individually adjust the lift cylinders and gauge wheel cylinders. A controller or controllers is used to purge air from the lift cylinders, gauge wheel cylinders, cylinders used to raise the shank frames for transport, and from the bypass circuits. The purge routine may be selectable as individual steps, hydraulic subsystem purges, or as one automatic purge routine.
