The present disclosure provides a single-degree-of-freedom (SDOF) magnetic damping shock absorber based on an eddy current effect, comprising a lower plate, a ring-shaped magnet a, a ring-shaped magnet b, an aluminum cylinder, a bottom copper sheet, a copper sheet, a top copper sheet, a bearing seat, a linear bearing, a bearing end cap, a load, a piston shaft, a stepped shaft, a fixed collar, a coil spring, a lower clamping shaft, and fixing screws. When the shock absorber is working, the ring-shaped magnet a keeps stationary at the lower end and the ring-shaped magnet b reciprocates in the vertical direction. Both magnets are arranged in a mutual attraction manner. Under the action of a time-varying electromagnetic field generated by the relative movement of the ring-shaped magnet b, the copper sheet arranged between the two ring-shaped magnets generates eddy current damping. The movement of the ring-shaped magnet b is inhibited.

A shock-absorbing front fork for a bicycle includes an inner part securely inserted in the crown of the front fork. The inner part includes multiple first slots and second slots defined axially in the outside thereof. Each first slot receives a pin therein, and each second slot receives a roller therein. A rod extends through a dust-proof unit, a first ring and a spring. The lower section of the rod is connected to the top end of the inner part. An outer part is a tube which includes multiple first grooves and second grooves defined axially in the inner periphery thereof. The outer part is mounted to the inner part. The pins are partially accommodated in the first grooves, and the rollers are partially accommodated in the second grooves. The outer part is axially movable relative to the inner part by the pins and the rollers with less friction.

An anchoring device for anchoring a floating object to an anchor structure, including a first attachment for being constrained to the floating object; a second attachment for being constrained to the anchor structure; a damping member for damping the relative motion between the attachments for securing the first attachment to the second attachment and including a sliding chamber, a piston for sliding in the sliding chamber according to a relative motion between the attachments and a damper for damping the sliding of the piston in the sliding chamber; and a control unit including a measurement sensor for measuring the sliding of the piston; and a control board for varying the damping of the damper according to the sliding of the piston detected by the measurement sensor.

A carcass stabilization system for a meat processing plant having carcasses transported along a processing line is provided. The system includes a stabilizer installed proximate the processing line and having a carcass engagement component and a shock absorbing device coupled to the carcass engagement component adapted to absorb at least some of the forces resulting from the carcasses impacting the carcass engagement component. The system also includes a stabilizing surface extending along the processing line opposite the stabilizer such that the carcasses are transported along the processing line between the stabilizing surface and the stabilizer, where the carcass engagement component is adapted to engage and bias the carcasses against the stabilizing surface.

A hydraulic shock absorber including a housing and an absorber unit. The absorber unit is movable relative to the housing in the axis direction of an absorber unit middle axis A-A and includes a piston which is arranged on a piston rod and which subdivides the housing into a first and a second working space which is filled with damping fluid.

A damper assembly comprises a main tube defining a fluid chamber. The main tube includes a first section, a second section, and an intermediate portion. A sleeve is disposed about the main tube. An external tube is disposed about the main tube and the sleeve. The external tube defines a compensation chamber between the sleeve and the external tube. A main piston divides the fluid chamber into a rebound chamber and a compression chamber. A piston rod couples to the main piston for moving the main piston between a compression stroke and a rebound stroke. The sleeve is in an abutment relationship with the second section of the main tube, radially spaced apart from the first section of the main tube, defining a compartment extending between the sleeve and the first section of the main tube. A housing for the damper assembly is also disclosed herein.

A damper comprises a pressure tube extending longitudinally between a first pressure tube end and a second pressure tube end, a piston arranged in sliding engagement inside the pressure tube, a piston rod coupled to the piston, a hydraulic rebound stop positioned in a first working chamber and including a sealing ring circumferentially extending around the piston rod and within the pressure tube. The sealing ring at least partially defining a high-pressure region within the pressure tube during a rebound stroke the damper further comprising a pressure relief valve in fluid communication with the high-pressure region. The pressure relief valve being operable to allow pressurized fluid from the high-pressure region to pass therethrough once a predefined pressure threshold has been reached.

A pneumatically adjustable lifting apparatus utilizes inflatable spring devices for lifting and precisely positioning a load at a desired location. Variations in the forces produced by the load cause the inflatable spring devices to expand or compress thereby allowing soft mating between components that need to be connected together, such as assembling or disassembling large threaded connections. Pneumatic pressure in the inflatable spring devices may be adjusted depending upon the particular load. The pneumatically adjustable lifting apparatus provides lightly damped vertical travel with a substantially linear force profile over a relatively wide displacement range. Recirculating linear ball bearings cooperate with the linear loading characteristics of the inflatable spring devices to minimize the vertical motion damping of the pneumatically adjustable lifting apparatus.

A door handle rate controller is disclosed. The door handle rate controller includes a damper assembly operatively connected to a door handle such that a movement of the door handle is dampened. The damper assembly may be a piston and cylinder type damper having a piston and a piston rod mounted within a body for reciprocal movement in the body along its longitudinal axis. The damper assembly extends longitudinally from a damper head to an end of the piston rod. A handle side mount and a mounting bracket may be provided to secure the damper assembly to a first and second portion of the door handle. The handle side mount has a first housing bracket pivotally coupled to the end of the piston rod, and a second housing bracket arranged to pivotally couple to the first portion of the door handle. The mounting bracket is defined by an first opening arranged to receive the damper head, and a second opening arranged to receive the second portion of the door handle. The mounting bracket is pivotally coupled to the damper head.
