Some embodiments provide ocean rig releases apparatus, systems and methods. In some implementations, a rig release apparatus comprises: a body having a first and second mating sections each being connected to one of two separate tethers; at least one locking shoe movably secured with the first mating section and movable between a first position configured to secure the first mating section and the second mating section together and a second position configured to allow the first mating section and the second mating section to separate; and a locking system configured to releasably lock the first and second mating sections and prevent hydrostatic pressure created by ocean depths from inadvertently unlocking, wherein the locking system comprises: a restraint system that inhibits the movement of the at least one locking shoe, and comprises a stop element that when released physically retracts to unlock the locking system allowing.

A telescopic baton is provided. The telescopic baton comprises a plurality of tubes sequentially arranged in an embedded manner, wherein a tube on an inner side of two adjacent tubes in the plurality of tubes is capable of extending and withdrawing along an axis direction of a tube on an outer side of the two adjacent tubes, a locking groove is formed in an inner wall of a first end of the tube on the outer side; a blade cam locking assembly, which comprises a socket sleeve, a plurality of blade cam blocks, a torsional spring and a fixing mechanism, wherein both extended ends of the torsional spring are respectively abutted against the socket sleeve and the blade cam block; an unlocking structure, which is mounted inside a tube on an outermost side of the plurality of tubes, and is used for unlocking the blade cam locking assembly.

A connector for connecting a component to a bolt has a base part and at least one holding part arranged displaceably on the base part. The base part has a connecting section for connecting to the component, a receptacle for receiving the bolt, and a clamping element which partially delimits the receptacle. The clamping element, in a delivery state of the connector, in which the bolt has not yet been inserted into the receptacle, assumes a first position and can be moved outward into a second position. The holding part has a first holding lug, which in the delivery state is arranged in a first latching recess of the base part or in the delivery state is arranged at a distance from the first latching recess of the base part.

The present invention is a low profile positive grip rim lock for use on off-road vehicle wheel assemblies utilizing standard safety rims, tires, and inner tubes. The rim lock provides a consistent grip with the bead of a tire regardless of the thickness of the bead of the tire, and never contacts the rim. The low profile eliminates the potential of having a pinch flat when the wheel assembly is impacted at the rim lock location.

The present application provides a mechanical connector adapted for coupling to a mating element, as part of muntin clip or a two part connector. The mechanical connector includes a body having at least one surface adapted for engaging a reciprocal surface of the mating element, wherein the at least one surface of the body of the mechanical connector slides across and frictionally engages the reciprocal surface of the mating element across a predefined distance during the coupling and decoupling of the mechanical connector relative to the mating element. The mechanical connector further includes one or more protruding elements, coupled to the at least one surface of the body of the mechanical connector, which extend in a direction toward the reciprocal surface of the mating element during engagement of the at least one surface of the mechanical connector with the reciprocal surface of the mating element, where the protruding elements is attached to the at least one surface at a first end of the protruding element and being free at the second end of the protruding element, and where the protruding element can separately flex along the length of the protruding element toward each of multiple directions including opposite directions. When the mechanical connector engages and slides relative to the mating element, the one or more protrusions are caused to flex in a direction that is substantially opposite a direction of the movement of the mechanical connector relative to the mating element along at least a portion of the predefined distance.

Embodiments of the present disclosure provides an anti-loosening device and a plunger pump. The anti-loosening device includes a first bracket, a second bracket and an elastic member. The first bracket includes a first clamping part defining a first accommodating space; a first connecting part extending in a first direction and fixedly connected to the first clamping part; and a limiting part fixedly connected to the first clamping part via the first connecting part, wherein the limiting part protrudes from the first connecting part in a second direction perpendicular to the first direction. The second bracket includes a second clamping part defining a second accommodation space, wherein the second clamping part is opposite to the first clamping part in the first direction; and a second connecting part extending in the first direction and fixedly connected to the second clamping part.

The present invention is an artificial grass block that can accommodate to the different sized cells of the similar grass pavement stones produced by different companies. The artificial grass block can bear an up to 10% size difference of the cells. The artificial grass block can carry out this function by its elastic, flexible positioning-fixing unit, which positions and fixes the artificial grass block inside the cell of a certain size range. The positioning-fixing unit is longer than the cell before insertion and deforms during insertion. This deformed positioning-fixing unit creates a tension that appropriately positions and firmly fixes the artificial grass block within the cell. EOIC 5/20 Pavings made of prefabricated single units; made of units of plastics; EOIC 9/225 Pavings specially adapted for allowing vegetation; EOIC 11/225 Paving specially adapted for through-the-surfacing drainage, e.g. perforated, porous; Preformed paving elements comprising, or adapted to form, passageways for carrying off drainage; E03F 11/00 Water supply; sewerage; Sewers; Cesspools; E04F 13/24 Finishing work on buildings; Coverings or linings, Hidden fastening means on the rear of the covering or lining elements; F16B 2/00 Friction-grip releasable fastenings; F16F 1/36 Springs, made of plastics.
