A refuse bin includes a liner sealed to a container. An inflatable space is between the liner and the container, and an inlet to the inflatable space conducts a flow to inflate the inflatable space from a deflated state to an inflated state. In the deflated state, the liner lines a cavity for refuse in the container. In the inflated state, the liner extends above the open end of the container. The flow into the inlet pushes the inflatable space toward the inflated state causing the liner to lift the refuse. The refuse bin may further include a lid-lifting mechanism activation by inflation of the inflatable space or an insert that helps shape the liner in the inflated state.

A system includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the system can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.

A loading system for a lighter-than-air craft hull that includes a vehicle that transports cargo containers into a hull loading area. This vehicle engages one of a set of longitudinal rails located inside the hull running fore and aft, where each rail has a unique vertical position and a unique horizontal position inside the hull. There is a crane to raise a particular container transported by the vehicle to the unique vertical position of one of the rails and to move it horizontally to the unique horizontal position of the rail. The crane attaches a rail wheel to the container and suspends the container from the rail. There is a rail tug that pushes or pulls the container along the rail forward into the hull to a final shipping location for that container.

An elevating device includes an upper connecting seat, a lower connecting seat, at least one scissors unit, and a hoist. The lower connecting seat is vertically movable relative to the upper connecting seat between an upper position and a lower position. The at least one scissors unit interconnects the upper connecting seat and the lower connecting seat. The hoist is operable to release a rope to thereby move the lower connecting seat to the lower position and convert the at least one scissors unit to the expanded state, and is further operable to retract the rope to thereby move the lower connecting seat to the upper position and convert the at least one scissors unit to the contracted state.

A transportation apparatus includes a delivering device, an elevating unit and a loading device. The delivering device is horizontally movable. The elevating unit is disposed under and mounted to the delivering device, and is vertically extendable and contractible relative to the delivering device. The loading device is adapted for loading and unloading an object, and includes a moving unit and a fork unit. The moving unit includes a moving base horizontally movable along a lower first axis parallel to a first direction relative to the elevating unit. The fork unit includes two fork prongs being horizontally spaced apart from each other along a second direction which is transverse to the first direction.

Method and apparatus for improved height adjustment of wall partitions. According to the present disclosure, an extendable Foot Controlled Elevator Device is placed beneath a wall partition. A user may then apply downward force on a Vertical Height Control to adjust the vertical position of the wall partition. In some embodiments, the Foot Controlled Elevator Device has a compressible base, allowing it to fit into tight areas (e.g., between toilets in a restroom under construction). In other embodiments, one or more Foot Controlled Elevator Devices may be linked, allowing for better control over the wall divider and simultaneous or distinct control of the respective Foot Controlled Elevator Devices.

A grinding mill for pulverizing material includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish in which the material is disposed, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the grinding mill can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.

Grate lifters for moving grating assemblies relative to supporting structures within which the grating assemblies are installed. A grate lifter may include a main body having a first end and a second end longitudinally opposite to the first end. A grate lifter may also include at least one hook member operably engaged with the main body at the first end and configured to engage one of at least one surface bar of a grating assembly and at least one cross member of the grating assembly. A grate lifter may also include at least one tab operably engaged with the main body at the second end and configured to engage at least one lock bar of the grating assembly. The at least one tab may be configured to be adjustable from an initial position to a bent position to engage the at least one lock bar of the grating assembly.

A system for transporting hydrogen from where it can be economically made to where it is most needed using airships. Green technologies can be used to generate electricity near to the primary energy sources. This electricity can then be used to produce hydrogen directly from water. Hydrogen can be delivered using an airship in which the hydrogen gas can also be used for generating lift, providing propulsion energy and serving ancillary needs. In other embodiments of the invention, the airship of the present invention can be used to dramatically reduce the cost of transportation of freight, the cost of passenger transportation, and to save on the area required for landing at the points of loading/unloading and embarkation/debarkation. And in another embodiment, the airship of the present invention can be used for transporting water and food to areas where needed. Various embodiments can load containers into and out of the ship.

Shoring blocks used as pedestal shoring under the cargo loading ramps of cargo planes and also used as sleeper shoring to support the weight of rolling stock loaded into cargo aircraft provide stackable foam structures of various and applicable shapes and sizes designed for particular cargo aircraft, each foam structure alternatively provided with a protective coating or fabric, reinforced with a stiffener or having fabric webbing integrated within or connecting more than one foam structure.
