Example weather barrier apparatus are disclosed herein. An example weather barrier apparatus includes a mount to couple to a wall of a loading dock and a seal coupled to the mount. The seal includes an outer flexible sheet having a first end and a second end. The seal includes an inner flexible sheet having a third end and a fourth end. The third end of the inner flexible sheet couples to the first end of the outer flexible sheet and the fourth end of the inner flexible sheet couples to the second end of the outer flexible sheet. The inner flexible sheet provides an edge seal and a surface seal. The edge seal engages a rearward facing edge of a vehicle and the surface seal engages surface panel of the vehicle when the vehicle is in engagement with the seal. A guide movably couples the outer flexible sheet and the inner flexible sheet. The guide is positioned between the respective ends of the inner and outer flexible sheets. The guide spaces apart a portion of the inner flexible sheet from a portion of the outer flexible sheet. The inner flexible sheet, the outer flexible sheet and the guide are to move between a first position and a second position in response to a force imparted to the weather barrier by the vehicle when the vehicle is in engagement with the inner flexible sheet to enable at least one of the edge seal to conform to a shape of the rearward facing edge of the vehicle or the surface seal to conform to a shape of the surface panel of the vehicle.

Example weather barrier apparatus are disclosed herein. An example weather barrier apparatus includes a support structure having a first end and a second end spaced from the first end, where the first end is to couple to a wall and the second end is movable relative to the first end. A seal is pivotally coupled to the second end of the support structure to define a pivot axis. The seal has a first sealing portion and a second sealing portion spaced from the first sealing portion. The first sealing portion is to engage a rear edge of a vehicle and the second sealing portion is to engage a surface of the vehicle spaced from the rear edge of the vehicle when the vehicle is in engagement with the seal.

The invention relates to an assembly comprising an unmanned transport device for delivering a shipment and a transfer device, said transfer device being designed to lower the shipment from the unmanned transport device to a receiving container, to lift the shipment from the receiving container to the transport device and/or to transfer said shipment between the transport device and the receiving container, the shipment being guided in each case by the transfer device.

A rail transport system comprising at least two runners having a shaped profile, a transport rail, and a transport carriage, the runners with a shaped profile being extended over a staircase or over a flat section and the transport carriage being moved along the transport rail. The transport carriage is provided with at least one electric motor. The runners having a shaped profile and the transport rail are stored in the transport carriage. A method for constructing a rail transport system and for transporting at least one container for loading or unloading the galley of an airplane, and a system for simultaneously loading and/or unloading the galley of an airplane.

A battery replacement robot with a mobile storage rack includes a mechanical part and an electrical control part. The electrical control part controls a battery replacement device to place, in one step, all battery boxes required by one side of an electric bus that needs battery replacement onto a battery box storage rack. A horizontal moving unit moves to a position where a battery needs to be replaced. A battery box replacement device takes down a spent battery box from the electric bus; the battery box replacement device rotates towards one side around a Y axis, and raises or lowers the spent battery box so as to put the spent battery on the battery box storage rack; then the battery box replacement device takes down a charged battery box from the battery box storage rack, rotates to the original position, and installs the battery box in the electric bus.

A system and method for mitigating dust migration at a wellsite is described. An oilfield material reservoir is provided for receiving oilfield material, the oilfield material reservoir having an enclosure. A dust collector is provided for collecting dust generated at the oilfield material reservoir, and a duct in communication with the enclosure and the dust collector is provided for transferring dust generated at the oilfield material reservoir to the dust collector.
