A variable height support with a platform and a base supporting the platform and reconfigurable to selectively change a height of a support surface on the platform relative to a subjacent surface. A control assembly is operable to selectively: a) maintain the support surface at a selected height; and b) release the platform to allow the base to be reconfigured to change the height of the support surface. The control assembly has a ratchet subassembly that, with the control assembly in a first state, allows the base to be reconfigured by exerting a continuous upward force upon the platform that causes the platform to elevate and be blocked within a range at a plurality of different vertical locations against downward movement. The control assembly further has an actuator that is repositionable to change the control assembly into a second state wherein the platform can be lowered over the range.

The method comprises a step 1) of digging a planting trough, a step 2) of laying a horizontal salt drainage system; a step 3) of laying a vertical salt drainage ventilation system; a step 4) of performing soil structure improvement; a step 5) of performing irrigation leaching and a step 6) of performing soil fertility improvement and nursery stock transplanting maintenance. According to the method, the leaching efficiency and a desalting effect of the coastal saline soil are improved. By adoption of the method, horizontal and vertical motion of irrigation leaching water in soil can be improved, irrigation leaching water salt leaching efficiency and drainage and desalting efficiency of the horizontal and vertical salt drainage systems are improved, and the saline soil improvement time is shortened.

Embodiments of the present invention are directed to apparati and associated methods for an easy on-off device to support and provide direct therapeutic cooling relief to the affected genitalia of persons having post-operative pain and swelling.

A tourbillon is provided that includes a platform rotatable about a platform axis. In one implementation, the platform carries an escapement including an escape-wheel and pallets, wherein the escape-wheel is rotatable about an escape-wheel staff, the pallets are rotatable about a pallet-staff, and the escape-wheel staff and the pallet-staff are disposed so as to be essentially parallel to the platform axis. The platform also carries a balance-wheel rotatable about a balance-staff, wherein the balance-staff is arranged at an angle of inclination ∝ with respect to the platform axis.

This invention is related to a retractable hitch-ball mechanism adapted for coupling to a frame of a vehicle, such as a pickup truck. The mechanism includes a support structure that is secured to the frame by a mounting-frame assembly, a housing having a tubular sleeve, a hitch ball member slidably disposed within the tubular sleeve, a drive plate, and a linkage coupled to the drive plate at one end and having a user-engageable portion at an opposed end. Upon a user exerting force on the opposed end, the hitch ball member is selectively movable between an extended use position, wherein a portion of the hitch ball member extends upwardly from the tubular sleeve, and a retracted storage position, wherein the ball portion is substantially hidden. Selective adjustment is facilitated by an inclined edge on the drive plate that slidably engages at least a portion of the hitch ball member.

A stabbing basket, for a rig and for supporting a worker while stabbing joints of tubular members together during running operations, comprises a frame member for mounting the stabbing basket to the rig, a platform to support the worker, a carriage to slidably mount the platform to the frame member, vertical power means for moving the carriage vertically with respect to the frame member, an articulating boom, interconnecting the platform with the carriage, said articulating boom comprising a first segment and a second segment, and at least one pivoting actuator positioned between the first segment and the second segment.

A fish luring device for bouncing on the floor of a body of water to attract fish. The device has a weighted body structured to allow easy vertical movement in the water, thereby increasing the speed at which the weighted body contacts the floor of the body of water. A coupling member is disposed on the weighted body for detachably coupling the weighted body to a fishing line and for coupling a leader line and fishing hook to the weighted body. A noise generating mechanism may be disposed in or on the weighted body for generating disturbances in the water and attracting fish.

The invention discloses a filter membrane clamping device with self-locking and damping functions. The filter membrane clamping device comprises a fixed seat and an air inlet seat, a suction nozzle isconnected at the lower end of the fixed seat, a lower sealing ring is arranged on the upper surface of the fixed seat, a buffer groove is formed in the upper surface of the fixed seat, the inner bottom surface of the buffer groove is connected with a limit seat through a fourth compression spring, an upper sealing ring is arranged on the lower surface of the air inlet seat, a filter membrane is mounted between the upper sealing ring and the lower sealing ring, and mounting blocks, bearings and adjusting blocks are connected on the left side and the right side of the fixed seat and sequentially distributed on the left side and the right side of the fixed seat from bottom to top. The filter membrane clamping device has self-locking and damping functions, the speed of the upper sealing ringcan approach to zero when the upper sealing contacts with the filter membrane, so that vibration can be furthest reduced when the clamping device replaces the filter membrane, and air quality and pollution sources of pollution gas are accurately evaluated.

An improved tin tag dispensing and nailing tool includes an operating member that is adapted for connection with a roofer's nailing gun, which operating member is guided by a pair of spaced vertical guide rods for vertical sliding displacement relative to the tool housing between an upper retracted position and a lower nailing position. The operating member is formed from a synthetic plastic material and contains vertical through bores that respectively receive the guide rods. Tubular oil-impregnated bushings are mounted in the through bores concentrically about the guide rods. A linkage arrangement connects the operating member with a shuttle plate that is displaced between a loading position adjacent the tin tag supply station and a discharging position adjacent the tin tag nailing station. An integral punched-out tongue portion extends upwardly at an acute angle from the shuttle plate for engagement with the lowermost tin tag of a stack.

An apparatus is provided for removing airborne moisture from a designated area. In one embodiment, the apparatus includes a bucket, a liquid absorption medium (such as ground corn cobs) placed in the bottom of the bucket to form a media bed, a tray placed over the absorption media bed, and a moisture absorption medium (such as calcium chloride) placed in the bucket over the tray. A method is also provided for absorbing moisture from a humid environment using the apparatus. When the apparatus is exposed to humid conditions, the CaCl₂ will absorb moisture and become hardened. As the CaCl₂ media hardens, it will expand. However, its lateral expansion is restricted by a side wall of the tray. Over further time, the CaCl₂ will begin to dissolve into a brine. The brine will gravitationally seep through the through-openings in the tray and be captured by the corn cob medium.

An apparatus for damping vibration in a vehicle structure via a mass of a spare wheel includes a bar. The bar has a first end elastically coupled to the vehicle structure, wherein the first end is arranged for vertical movement relative to the vehicle structure. The bar also has a second end pivotably coupled to the vehicle structure, wherein the second end is arranged to facilitate the vertical movement of the first end. The bar additionally includes an arrangement for mounting a spare wheel, wherein damping of vibration in the vehicle structure is provided when the spare wheel is mounted on the bar.
