A lock for an aircraft door. The lock includes an outer shell having an inner cavity. A core is rotatably mounted within the inner cavity to rotate about an axis of the core. The core has a keyhole extending through the core from a first end of the core for receiving a key therein, to an opposed second end of the core. The keyhole defines an air leakage path through the core. A cam has a cam arm mounted about the core and is rotatable therewith. The second end of the core protrudes from the cam. A cover is attached to the second end of the core. The cover blocks the keyhole at the second end of the core and obstructing the air leakage path. An aircraft door, methods, and a retrofit kit are also disclosed.

Apparatus to protect sealing surfaces of thief hatches are disclosed. An example apparatus includes a first portion that is attachable to a tank, wherein the first portion includes a first opening, and a second portion that is pivotably coupled to the first portion. The example apparatus is structured to provide access to an aperture in the tank via the first opening when the second portion is in an open state and maintain a pressure of the tank within a specified range by selectively separating one or more seals from one or more corresponding sealing surfaces when the second portion is in a closed state, wherein the second portion includes the one or more seals and the one or more corresponding sealing surfaces.

A cover is configured to selectively engage with a portion of a structure in response to receiving a wireless electrical power signal at a receiver antenna of the cover from a wireless power source located in an outside environment, to separate a first environment on a first side of the cover from a second environment on a second side of the cover opposite the first side. In response to wirelessly receiving the electrical power signal, a fastening subassembly of the cover changes from a secured mode configured to inhibit opening a cover body with respect to the structure, to an unsecured mode configured to facilitate opening the cover body with respect to the structure. This in turn allows the cover to be matingly engaged with a portion of the structure to form a smooth continuous surface, without any exposed fasteners on the exterior side of the cover.

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.

A washing machine appliance equipped with door reversing locking and latching features is provided. Particularly, the washing machine appliance includes latching assembly that is movable between various mounting positions and is configured to hold the door in a closed position. A hinge assembly rotatably couples the door with a cabinet of the washing machine appliance and is movable between various mounting positions so that the door swing direction may be reversed. The washing machine appliance also includes a locking assembly for locking the door in the closed position, e.g., during operation of the washing machine appliance. The locking assembly is separate and distinct from the latching assembly and need not be moved when reversing the swing direction of the door.

An actuating system for an actuatable door that comprises at least one latching device with a latching hook that is adapted for locking the actuatable door in a closed position, the latching hook being pivotally mounted to an associated pivot bearing and connected to a pivotable mechanical transmission element via a coupling link, which is pivotally mounted to the latching hook and to the pivotable mechanical transmission element, the pivotable mechanical transmission element being coupled to a rotatable latching shaft, wherein rotation of the rotatable latching shaft in operation results in pivoting of the pivotable mechanical transmission element and pivoting of the latching hook around the associated pivot bearing, wherein the pivotable mechanical transmission element is mounted onto the rotatable latching shaft. The invention is further related to an actuatable door having such an actuating system.

A fastening device for axially fastening a rotatably mounted threaded pin to a closing element, in particular a door, having a fastening element, which can be screwed onto the threaded pin, and having a backward-rotation prevention means for securing the screwed-on fastening element, wherein the backward-rotation prevention means has a sealing region for sealing the threaded pin with respect to the closing element. The disclosure also describes a closure actuator and a closing element incorporating the fastening device.

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 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 handle having an airtightness function used for a casing of a negative pressure type dust collector is provided. Two pivot seats are fixed to a door of the casing and vertically aligned with each other. A rotating shaft is pivotally connected to the pivot seats. Two ends of the rotating shaft are provided with eccentric blocks, respectively. Two engaging blocks are located close to the outer periphery of the door and vertically aligned with each other. The eccentric blocks are engaged with the engaging blocks to exert a force to the door so that the door is closely attached to the casing, thereby enhancing the airtight effect of the casing and preventing the door from being deformed due to backwash and preventing the dust from flowing out through the gap between the door and the casing to cause secondary environmental pollution.
