A manway open and close assist device that is operably connected to at least one upper hinge attachable to a manway cover and a lower hinge attached to a vessel or tank. The device comprises. A disc-like piston is mounted on a threaded input screw and at least one anti-rotation member to provide linear translation of the piston due to rotation of the input screw. A cylindrical and tubular housing that receives the threaded input screw, the anti-rotation member, and the piston, wherein the housing has a plurality of helical grooves disposed in its inner surface that receive teeth on the outer surface of the piston. The housing may be fixed to the upper hinge member(s) and a rotation of the housing and attached hinge member(s) is effectuated by rotating the input screw and resulting linear movement of the piston to open and close the manway cover.

Securing systems and methods of securing a transport container to an attachment point. In one embodiment, the securing system includes an actuator, an attachment structure, and an electronic controller. The attachment structure is dimensioned to complement the actuator. The electronic controller is operably coupled to the actuator for attaching and releasing the actuator to the attachment structure.

A hinge is connectable with two housing shells for permitting relative folding and unfolding of the housing shells, and includes a fixed seat, at least two rotating units, two lateral support plates and at least one synchronous driving unit. The rotating units are shiftable between an open state and a closed state. Each rotating unit includes a linking member fittingly and arcuately slidable on the fixed seat, a sliding member fittingly and arcuately slidable on the linking member, and a rotary bracket pivotably mounted on the fixed seat and inclinedly slidable on the sliding member. The lateral support plates are respectively mounted on the linking members. The synchronous driving unit includes two inboard pinions and two outboard pinions arranged laterally to mesh with bracket toothed portions of the rotary brackets to make synchronous rotation of the rotary brackets in opposite rotational directions.

The lid opening and closing mechanism in the present disclosure has an operating member which is displaceable relative to a housing body, and a drive mechanism. When the operating member is in a first position relative to the housing body, the drive mechanism locks the lid so that the lid does not move in a predetermined direction, and when the operating member is moved to a second position relative to the housing body, the drive mechanism releases the lock on the lid, moves the lid in the predetermined direction by at least a predetermined distance, and separates the lid from a predetermined face in a direction perpendicular to the predetermined face.

An angularly positionable flexible display device includes a flexible display, a first substrate, a second substrate, and a positionable hinge mechanism which is disposed in a mounting space defined between the first and second substrates. In response to application of a manual force upon at least one of the first and second substrates, the first substrate is angularly displaceable relative to the second substrate through the positionable hinge mechanism to permit the flexible display to be bent with the angular displacement of the first and second substrates. Once the manual force is release, the first substrate is angularly positioned relative to the second substrate through frictional force provided by the positionable hinge mechanism.

A foldable module and a flexible display device are provided. The foldable module includes a metal frame disposed along a periphery of a flexible display panel, a protective housing configured to hold the flexible display panel and the metal frame, and a flexible hinge for securing to the protective housing. The flexible hinge includes rotating shafts, fixed washers, biasing gaskets, movable washers, and disc springs. The flexible can achieve that it is positioned within a predetermined angular range.

A hinge assembly including a flat plate and a bent plate is provided. The flat plate includes a first slot extending at least partially along a width of the flat plate and disposed substantially perpendicular with respect to a central axis of the flat plate. The bent plate includes a first portion, a second portion, and a third portion. The second portion includes a second slot extending at least partially along a width of the bent plate and disposed substantially perpendicular with respect to a central axis of the bent plate. The second slot is adapted to interconnect with respect to the first slot to pivotally move the hinge assembly between an open position and a close position. In the open position, the first portion of the bent plate is adapted to contact a first half section on a first side of the flat plate.

This disclosure provides a middle frame and a flexible display device. The middle frame comprises a first framework component, a second framework component and a flexible component comprising a first chain link element, a second chain link element, a third chain link element, a fourth chain link element, a flexible element and a plurality of rotors. Under collaboration of the plurality of the rotors, the third chain link element is connected to the first framework component and the third chain link element, the third chain link element is connected to the flexible component, the second chain link element is connected to the second framework component and the fourth chain link element, and the fourth chain link element is connected to the flexible component.

Technologies are described for a hinge mechanism coupled to at least a dual-display device wherein the displays can rotate with respect to each other through 360 degrees. The hinge mechanism has at least one flexible connection member that follows a generally S-shaped path when the displays are in a tablet position. In some embodiments, a second flexible connection member can be added that follows a mirrored S-shaped path. The S-shaped path of the first flexible connection member and the mirrored S-shape path of the second flexible connection member together create a cross-configuration. In other embodiments, interconnected friction hinges can allow for a free-stop function at any point along the 360 degrees of rotation.

Provided is a storage container including a base and a cartridge container attachable to the base. The cartridge container defines a plurality of internal chambers and includes a plurality of individually operable doors, each of the plurality of doors corresponding to one of the internal chambers. The storage container further includes a plurality of individually addressable actuators disposed in at least one of the base and the cartridge container, each of the plurality of actuators corresponding to one of the doors. A microprocessor is programmed or configured to receive at least one instruction from a server computer, and transmit a command, based on the at least one instruction, to actuate one of the plurality of actuators. Actuating one of the plurality of actuators causes the corresponding door to move from a closed position to an opened position. Systems and methods are provided for remote and immediate dispensing of articles.
