A locking device for restricting access to a hatch of a pressure vessel, and, more specifically, a locking device that is responsive to the internal pressure in the pressure vessel so as to minimize the ability of one to open the hatch while the vessel is still pressurized. In some embodiments, the locking device comprises first and second portions of the locking device configurable between an open and a closed configuration and a pressure-responsive locking member in fluid communication with an outlet port of the pressure vessel and arranged to automatically retain the first and second portions in the closed configuration when the pressure inside of the pressure vessel is above a predetermined threshold, wherein in the closed configuration the first and second portions restrict manipulation of the hatch and/or a locking mechanism of the hatch.

A door sealing system for a container having a container door is provided. The container can be part of a vacuum system, for example as mounted on a trailer. The sealing system is hydraulically actuated and includes a mechanical lock. A corresponding vacuum system and method of operation are also provided.

An actuating system for an actuatable door and to an actuatable door having such an actuating system are provided. The actuating system comprises first and second rotatable latching shafts, a coupling link, first and second pivotable mechanical transmission elements that are mounted onto first and second rotatable latching shafts, respectively, and first and second latching members. First and second latching members are non-rotatably mounted to the second rotatable latching shaft and adapted for latching the actuatable door in a closed position. A first rotation of the first rotatable latching shaft results in pivoting of the first and second mechanical transmission elements and a second rotation of the second rotatable latching shaft, which causes a third rotation of first and second latching members.

A floodgate is disclosed. The floodgate comprises: a panel for installation at a doorway to form a barrier against flooding; a hinge, the panel being movable between an opened position and a closed position about an axis of the hinge, the axis extending in use in an upright direction; and a sealing element coupled to an edge of the panel to provide sealing engagement with the ground when the panel is in the closed position thereby forming the barrier against flooding; wherein the hinge is configured to corporate with the panel to, upon the panel being moved from the closed position towards the opened position, cause the panel to move away from the ground thereby releasing the sealing engagement between the sealing element and the ground.

A locking system for an enclosure, including a control bracket mounted to a door of the enclosure and configured to slide in a longitudinal direction along a guide rod running through a pin bracket of the control bracket. The control bracket further includes a latching pin to secure the door of the enclosure. A handle mechanism has a push rod that causes the control bracket to slide along the longitudinal direction, also causing the latching pin to move into a position that secures the door.

A compression latch having a body including a cup having a well defining a first side of the compression latch, an exterior portion defining a second side opposite the first side, and a raised portion defining a peripheral rim surrounding the cup, the peripheral rim providing an uppermost surface of the cup is disclosed. The compression latch has a T-shaped handle mounted to the body, the T-shaped handle being foldable and reversible and having a cam lock mounted thereon, the cam lock having a keying element on one side of the handle and a rotatable locking cam on the second side of the handle, wherein when the T-shaped handle is folded in a first position, the keying element is exposed and does not protrude beyond the uppermost surface of the cup and when the T-shaped handle is reversed and folded in a second position, the rotatable locking cam is exposed and does no protrude beyond the uppermost surface of the cup.

An electronic device sealing arrangement includes a housing, an access door, a sealing member sized and configured to be sealingly compressed between the access door and the housing, a latch in operable communication with the housing and the access door, the latch being configured to compress the sealing member between the access door and the housing when moved to a position that latches the access door in a closed position, and a resilient member in operable communication with the latch and at least one of the housing and the access door, the resilient member being configured to at least partially compress when the access door is latched in the closed position and the sealing member is compressed between the access door and the housing.

A watertight door or window comprising a frame and a leaf mounted on the frame and arranged movably with respect thereto between an open position and closed position, and further comprising: a striker element arranged on the leaf, a locking element arranged on the frame and provided with a hook end designed to engage with the striker element so as to lock the leaf against the frame following closing of the leaf, and a striker actuating mechanism arranged on the leaf and able to be actuated when the leaf is in a closed position and the locking element is engaged with the striker element. The actuating mechanism is provided for releasing the striker element from a closed position, where the striker element is positioned inside a recess in the hook end of the locking element, to an open position, where the striker element is extracted from the recess in the hook end of the locking element. The actuating mechanism can be reset when the leaf is closed again.

An electronic device sealing arrangement includes a housing, an access door, a sealing member sized and configured to be sealingly compressed between the access door and the housing, a latch in operable communication with the housing and the access door, the latch being configured to compress the sealing member between the access door and the housing when moved to a position that latches the access door in a closed position, and a resilient member in operable communication with the latch and at least one of the housing and the access door, the resilient member being configured to at least partially compress when the access door is latched in the closed position and the sealing member is compressed between the access door and the housing.

A locking system for an enclosure, including a control bracket mounted to a door of the enclosure and configured to slide in a longitudinal direction along a guide rod running through a pin bracket of the control bracket. The control bracket further includes a latching pin to secure the door of the enclosure. A handle mechanism has a push rod that causes the control bracket to slide along the longitudinal direction, also causing the latching pin to move into a position that secures the door.
