This disclosure includes a manhole cover locking device, system, and kit, each configured for locking a manhole cover in a closed position overtop an access opening of a container, the access opening being arranged at one end of a collar extending outwardly from the container, each comprising: a body; a mechanism for connecting the body to a pre-existing portion of the manhole collar or the container; and, a mechanism for securing the body to the manhole cover to prevent the opening of the manhole cover using a pre-existing portion of the manhole cover. Each mechanism may be tamper resistant. The disclosure also includes methods of installing and using the device, system, and kit.

A receptacle is provided for holding a quantity of solid material. The receptacle includes a container having an open end, and a gate operably connected to the container so as to be rotatable to a closed position structured to prevent solid material from exiting the container through the open end. The gate includes a locking arm mounted thereon. A latching mechanism is operably connected to the container and includes a latch rotatable to a latched orientation structured to contact the locking arm to prevent the gate from being rotated out of the closed position. The locking arm is structured to move rearwardly and upwardly during rotation of the gate out of the closed position. The latch is structured so that contact between the latch and the locking arm when the latch is in the latched orientation prevents rearward and upward movement of the locking arm.

A bulk material discharging system includes a transmission station including a transmitting vessel having a transmitting vessel inlet configured to receive bulk material from an outlet of a bulk material transporter, and a transmitting vessel outlet to transmit bulk material therefrom. The system also includes a transporter handling station located operatively upstream of the transmission station and including at least a portion of a transporter handler including at least one carriage with transporter couplings configured to engage corresponding carriage couplings of the bulk material transporter and configured to convey the bulk material transporter over the transmitting vessel.

An inertable container (10) for transporting an additive manufacturing powder comprises an inertable volume (12) and a main opening (14) granting access to the inside of this inertable volume, the inertable volume (12) comprising an upper portion (16) and a lower portion (18), the main opening (14) being located in the lower portion (18) of the inertable volume, and the section (S12) of the inertable volume (12) increasing gradually over at least part of the height (H10) of the container (10) and from the lower portion (18) towards the upper portion (16) of the inertable volume. The main opening is equipped with a passive half-valve (20) allowing this main opening (14) to be closed in such a way as to be sealed in an airtight and humidity-proof manner. The container comprises at least two inerting tappings.

A manway gate assembly couples to a tank and provides a liquid tight seal. The manway gate assembly includes a gate selectively slideable in a first linear direction between an open position, a closed position, and/or an intermediate position between the open position and the closed position. The manway gate assembly includes one or more locking members arranged adjacent to the gate and moveable between a locked position and an un-locked position. When in the locked position, the one or more locking members apply a biasing force to the gate in a second linear direction perpendicular to the first linear direction to seal the gate to the tank and provide a liquid tight seal.

Disclosed is a closure for a door of a shipping container. The closure includes a housing, an outside handle pivotally mounted relative to the housing, an inside handle pivotally mounted relative to the housing, and a catch connected to the inside handle. The closure is configured so that movement of the inside handle between a first position and a second position causes corresponding movement of the catch. A locking mechanism can releasably fix the inside handle relative to the outside handle, such that when in a locked position rotation of the outside handle causes corresponding rotation of the inside handle and when in an unlocked position the inside handle can be rotated independently of the outside handle.

A latch for securing a component to a track in a base of air cargo equipment, such as a pallet or the floor of a unit load device. The latch includes a rigid support configured to be attached at the bottom edge of the component. The latch also includes a handle. The handle rotates relative to the support between an open position and a closed position. The handle uses a rotationally tapered locking cam to secure the component to the track. In one embodiment, the component is a door, such as a fabric curtain.

A modular portable storage container system includes a storage container having first and second sections. The first section defines a first partial volume of storage space and the second section defines a second partial volume of storage space. The system further includes a lock mechanism with a lock arm, lock handle, and pivot shaft defining an axis of rotation. The lock arm and handle are fixed for common rotation with the pivot shaft. The arm extends radially outward from the pivot shaft to a roller assembly. A lock track is disposed within the second section and extends from a fluted open portion to a closed end, with a continuous track portion disposed therebetween. The first and second sections are movable between at least closed and open positions. In the closed position, the roller assembly engages with the lock track and retains the first section in contact with the second portion.

A cover assembly for a container including a frame having a rail, a cover coupled to the frame, a first opening mechanism including a first pivot and a first slide housing, and a second opening mechanism including a second pivot and a second slide housing, the rail of the frame being selectively and slidingly receivable in the first and second slide housings. The cover and frame are movable between three positions, a closed position, a first open position wherein the rail is partially disposed in the first slide housing and is disengaged from the second slide housing, and the frame, cover and first slide housing are rotated about the first pivot, and a second open position wherein the rail is partially disposed in the second slide housing and is disengaged from the first slide housing, and the frame, cover and second slide housing are rotated about the second pivot.
