A display hoist includes a first clamp configured to be coupled to a first portion of a telescoping support member, a second clamp configured to be coupled to a second portion of the telescoping support member, and an actuator assembly extending between the first clamp and the second clamp. The actuator assembly includes an actuator motor, a piston including a first end and a second end, the first end of the piston mechanically coupled to the first clamp, the second end of the piston operably coupled to the actuator motor, and a housing disposed over at least a portion of the piston and enclosing the actuator motor, the housing including a top end and a bottom end, the housing mechanically coupled at the top end to the second clamp.

A lift system includes a base and a vertical structure from which a plurality of tines projects. The tines are configured to engage a lower surface of a plurality of dairy trays within a stack of dairy trays in order to facilitate lifting part of a stack of dairy trays to access or remove a tray that is lower in the stack. In one embodiment, a plurality of pairs of tines are movable from a low position where they can engage a plurality of stacked trays to a raised position where there is space between each of the adjacent trays.

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.

A refrigerator includes a body and a drawer. The body includes a storage compartment. The drawer is insertable or withdrawable into or from the storage compartment. The refrigerator also includes a support configured to supports an item accommodated in the drawer. The refrigerator further includes a lifting device configured to lift the support with respect to the drawer. The lifting device includes a driving part that provides a driving force to the support, a wire that transfers the driving force of the driving part to the support, and at least one pulley which guides the wire.

Technologies are described for restraining systems. The systems may comprise a base, a stationary arm, a swing arm, a rod, first straps, and second straps. A bottom end of the stationary arm may be attached to a first end of the base. A bottom end of the swing arm may be attached at a second end of the base. The rod may be attached to top ends of the stationary arm and the swing arm. First straps may be attached to the stationary arm and configured to loop around and support an object. Second straps may be attached to the swing arm and configured to loop around and support the object. The rod may move and push the top of the swing arm away from the top of the stationary arm. A friction force between the first and second straps and the object may be effective to restrain the object.
