A clutching adjuster having a housing with a nose, the nose including a plurality of discrete helically-shaped thread segments, a ball stud journaled by a ball stud bore for axial movement therethrough and passing through the nose of the housing, the ball stud having a threaded portion, an unthreaded portion, a ball, and a drive spline portion, an outbound annular travel barrier and an inbound annular travel barrier, wherein, in length of travel clutching operation and end of travel clutching operation where the ball stud is axially rotated through the ball stud bore, the receipt of an undue axial force of resistance on the ball stud results in outward deflection of engaged thread segments, thereby allowing the threaded engagement between the threaded portion of the ball stud and the thread segments to clutch.

A landing leg assembly for a heavy duty commercial vehicle includes a first leg member defining an interior space, a second leg member telescopingly engaging the first leg member and movable between a retracted position and an extended position with respect to the first leg member, a gear assembly at least partially located within the interior space of the first leg member and operably coupled to the second leg member and configured to receive an input from a user to move the first leg member between the retracted and extended positions, the gear assembly including a shaft member and a gear member fixed for rotation with the shaft member, and an integral, single-piece bearing member including a bore that rotatably receives the shaft member, wherein the bearing member comprises a powdered metal and is directly welded to the first leg member.

A feeder for pigs includes a hopper and a trough for receiving the feed where an elongate opening is defined by an elongate shelf to control the amount of feed discharged from the hopper to the trough. An adjustment linkage for lifting the shelf against the weight of feed in the hopper includes a first lift screw and a second lift screw each for applying a lifting force to the elongate adjustment member located at spaced positions from the end walls of the hopper. Each of the screws includes a gear box with a shaft connected between the two gear boxes to communicate drive therebetween for simultaneous operation of the lift screws by a hand crank connected to one at the top of the feed in the hopper.

A bed assembly includes a bed having a head end, a foot end and a frame which is connected between the head end and the foot end. A water-proof pad is located between the head end and the foot end. The water-proof pad can be tightened, loosened and movable up and down. A bed board unit is pivotably connected to two sides of the frame so that the bed board unit is opened and closed when needed. An inflatable tub or bedpan is located beneath the bed so that when the bed board unit is opened, the patient can use the inflatable tub or the bedpan and does not have to be removed from the bed.

A flexible display module middle frame is provided. The flexible display module middle frame includes: a first frame, configured to connect with a first non-bending area of a flexible display module; a second frame, configured to connect with a second non-bending area of the flexible display module; a bending structure connected to the first frame and the second frame and configured to control the first frame and the second frame to rotate relative to each other; and a first sliding connection frame connected to a side of the first frame away from the second frame, a second sliding connection frame connected to a side of the second frame away from the first frame.

An opening and closing structure for an umbrella combining automatic and non-automatic modes including an electric mechanism, a cranking mechanism and a clutch structure is described herein. The electric mechanism includes a screw rod, a motor and a first transmission element. The motor is configured to drive rotation of the screw rod, and the first transmission element is mounted at the screw rod. The cranking mechanism includes a second transmission element and a cranking handle. The second transmission element is engaged with the first transmission element, and the second transmission element is connected with the cranking handle via the clutch structure. The invention overturns a conventional method of using an electric umbrella, and provides a manual lifting-and-lowering function under the premise of maintaining a electric lifting-and-lowering function, that is, in case of insufficient or no power supply, the umbrella can be opened and closed through the cranking handle.

An actuator gearbox includes a drive shaft including a plurality of gear linkages that are spaced apart along the drive shaft, and a plurality of output shafts adjacent respective ones of the plurality of gear linkages. Each of the gear linkages includes a fixed gear coupled to one of the plurality of output shafts and a moving gear that is slideably coupled to the drive shaft. A bias spring is coupled to the moving gear to urge the moving gear out of engagement with the fixed gear. The mechanical switch moves the moving gear into engagement with the fixed gear on the output shaft adjacent the linkage to thereby cause the output shaft to rotate in response to rotation of the drive shaft.

An adjustable strut that includes an outer housing configured to receive an extendable member, and an extending mechanism with a gear system configured to convert rotation motion of an input mechanism into linear translation of the extendable member.

The RET adjuster includes a drive assembly with a rotatable drive member operatively connected to a phase shifter assembly such that rotation of the drive member adjusts the phase shifter assembly. A first connector is coupled to the drive member where the first connector occupies a rest positon when the drive member is at rest. A drive system has a second connector occupying a rest positon when the drive system is at rest where the second connector is releasably engageable with the first connector such that actuation of the drive system rotates the drive member. A mechanical calibration system locates the second connector at the second rest position.

Machining tool comprising a frame in which a drive shaft for a tool is mounted so as to pivot about a rotation axis and to move axially along the rotation axis. The shaft is connected to two rotary motors, namely a first motor connected to a member for meshing with a fluted portion of the shaft in order to drive the shaft in rotation and a second motor connected to a nut engaged with a threaded portion of the shaft in order to move the shaft axially. The motors are connected to at least one control unit designed to control the motors independently of one another, and the first motor and the second motor are coaxial with one another.
