A self-tightening culling clip used to secure a marker to a fish for quick identification of the fish in a livewell, for example. The self-tightening culling clip has handles coupled together about a handle pivot and a marker attached to a lift-pivot. A spring forces the jaw end of the handles together and a user may squeeze the handle end of the handles to open the jaws for attaching to a fish. When the marker is lifted, the handles pivot about the handle-pivot to apply force to close the jaws, thereby creating a self-tightening culling clip. A pair of links extend from the lift pivot to the handles and these links for the handle end of the handles outward when the marker is lifted. The marker may have a distinctive identifier color and/or character.

Disclosed is a sample collection apparatus. The sample collection apparatus relates to a sample collection apparatus configured to be capable of stably collecting sediment from a seabed without disturbing the same and to be capable of easily separating and transporting a box itself containing a sample from the sample collection apparatus. Briefly, the sample collection apparatus includes a frame section, a vertical operation section, and a rotary operation section.

A floating lift includes a fixed frame, a movable frame, and a platform coupled to the movable frame. A float that may include multiple float sections is coupled to the fixed frame to provide buoyancy to the lift. A lifting assembly is structured to move the movable frame to change a position of the platform relative to the fixed frame over a range of travel between a raised position and a lowered position. A vehicle can be loaded on the lift in the lowered position and elevated to the raised position to avoid damage to the vehicle. The range of travel of the platform is greater than a length of a lifting arm of the movable frame and the lifting assembly includes a locking link to lock the lift in the raised position. The lift may also include a leveling assembly that assists with uniform movement of the movable frame.

A device for efficiently separating ethyl tin from molten crude tin is disclosed. The device includes grab buckets, connecting rods, an inverted T-shaped push rod, alloy legs, a hanger plate, a cylinder and a lifting ring; wherein one end of the connecting rod is fixedly connected with one side of the grab bucket, and the other end of the connecting rod is detachably connected with the bottom end of the inverted T-shaped push rod; a top flange of the inverted T-shaped push rod is detachably connected with the bottom flange of the cylinder through threads, and the inverted T-shaped push rod is powered by the cylinder to push and pull. The device has simple structure, small volume, light weight, convenient use and placement, reduced occupancy rate of production site space and flexible use; the invention adopts a remote control mode, mechanized operation, higher safety and labor saving.

A clamshell bucket assembly including first and second pivotally connected steel bucket halves rotating between open and closed positions and including sediment retention bars secured between the overlapping sides define a scoop for permitting outflow of water while retaining a volume of a dredged material. Weld rivets provide reinforced securing of the side and bottom steel portions of each bucket half and extend a thickness of the bucket halves to prevent fracturing at the welded interface. Upper and lower sheave assemblies provide increased durability and wear resistance during repetitive opening and closing of the mechanical bucket halves. The sheaves each include a central pin supporting hub collar formed from a plurality of progressively inwardly stepped and stacked disc shaped plates, these being initially sectioned from a hardened steel sheet and welded to form the hub at the highest zone or area of stress exerted upon the sheave during operation of the bucket.
