A ball screw adapted to detecting coolant liquid includes a screw, a nut, a plurality of sealing members, a sensor, a signal processing unit and a cover. The nut includes a main body and an end surface, and a through-hole and a flow channel are disposed on the main body. The nut is threadedly disposed on the screw via the through-hole. A plurality of openings are disposed on the end surface, and the openings communicate with the flow channel. The sealing members are disposed in the plurality of openings. The sensor is disposed on one of the sealing members to detect a pressure of the coolant liquid and output an original signal. The signal processing unit is electrically connected to the sensor to receive the original signal and convert the original signal to a digital signal. The cover is disposed on the sensor and fixed to the nut.

Fully rotating rotary actuator of a multi-purpose machine in which an axle supports the frame of a felling head by a bearing mount, there being a rotary mechanism driven by a rotary motor between the axle and the frame, and in which the connection of the axle includes rotatable joints, the axle includes conduits for electrical cables and a processing fluid line, and in which an additive fluid line tube is arranged in the conduit in the axle and connected to its lower end is a rotatable connector, which is connected to a second tube fastened in the frame for the application of the additive fluid.

An adjustable non-view obscuring umbrella having a canopy and a support structure. The support structure having a support post, a plurality of non-articulating umbrella ribs, and at least one articulating umbrella rib. An articulating umbrella rib having an upper rib member, a lower rib member, and an umbrella rib articulation mechanism. An umbrella rib articulation mechanism having an upper bracket and a rotation actuation member, wherein the rotation actuation member is rotationally coupled to the upper bracket.

Channel joints (1) can permit bonding a tube or tubular member (30) to an end fitting (20) in double shear. The channel joint may include a receiving channel (25) in the end fitting (20) that is complementary in shape to the tube, tubular member, or other hollow member (30) that is to be fitted and bonded with the end fitting. The use of a channel joint allows for simplified assembly because the receiving channel acts as a reservoir for the bonding agent or adhesive (50). Upon insertion of the tube, tubular member, or other hollow member into the adhesive-loaded receiving channel, the adhesive will backflow to fill the voids in the joint and expel the excess adhesive.

A boot with a body cavity that protects a moveable joint and retains lubricant associated with the joint is disclosed. The wall of the boot body includes a venting aperture that is protected by a surrounding barrier structure.

A dust hoot for a moveable joint is provided. The dust boot includes a boot body disposed annularly about an axis and defining an interior cavity. The boot body has a housing opening at a first longitudinal end for attaching to a housing and a shank opening at a second longitudinal end opposite the first longitudinal end for sealingly engaging a shank portion of a ball stud of the ball and socket joint assembly. The boot body defines a plurality of longitudinal strengthening portions formed therein and extending longitudinally at an acute angle relative to the axis in a relaxed condition of the dust boot for resisting rotation of the dust boot in response to a rotation of the ball stud and for improving sealing of the dust boot with the shank portion of the ball stud.
