In one embodiment of the present disclosure, a switch for a powered pallet conveyor is provided. The switch comprising (a) a turntable and (b) rail portions which are arranged upon the turntable and define at least a first travel pathway and a second travel pathway, whereby the first travel pathway is defined by straight rail portions and a second travel pathway is defined by curved rail portions, so that the central line of the first travel pathway and the departure lines of the second travel pathway respectively pass through the fulcrum of the turntable.

A system and method for automated handling, transferring and storing conventional cargo storage containers on a cargo ship wherein the containers are stored in a multi-tier cell system and are manipulated by powered transfer units which are selectively moveable along an intersecting overhead track system such that containers may be simultaneously retrieved from, moved or placed within any of the cells of the ship. The transfer units are equipped both with hoists, which control spreader beams which are selectively secured to the cargo containers, and guide stabilizers, which prevent undesirable movement of the cargo containers when they are elevated above the cell structures such that the containers may be manipulated even during rough sea conditions such that the system is essentially continuously operable as a floating supply distribution system.

The Personal Mass Transit (PMT) system utilizes a removable vehicle conveyance apparatus and method for conveying transit vehicle car-pods and their contents from one transit station to another autonomously. Vehicle conveyance apparatus are stored off-line in storage silos and other areas awaiting on-demand transit system instruction to pickup vehicles at loading points and convey them to different stations as requested by occupants or pre-programmed instructions. The PMT system further utilizes a number of transmitter-receivers nodes and control computers to manage all aspects of operation of the transportation system. Any number of different types of PMT vehicles could ride the transit system when equipped with the correct coupling points and remain under the maximum combined curb weight of any particular area or type of transit track in order to be transported on the PMT system.

A crane trolley, especially a single-rail trolley with a short overall height, with a traveling mechanism frame (2) having a hoisting mechanism (1), which can travel by running wheels (3, 3a) on a rail, especially a lower flange (4a) of an essentially horizontal beam (4), wherein at least one running wheel (3a) can be driven, and a friction roller (10) interacting with the driven running wheel (3a) is arranged on the underside (4b) of the rail. In order to create a crane trolley that guarantees a reliable reduction in the slippage of the driven running wheel (3a) with a simple design, a pair of friction rollers (10) is provided, which may be positioned against the underside (4b) of the rail by adjusting the spacing from each other via a common pressing mechanism.

A platform including a rotatable turntable apparatus for attachment to a boat deck, or the cargo space of a pick-up truck or the cargo space of an all terrain vehicle, or other area where a person with impaired mobility needs to experience greater mobility to engage in fishing, boating, wild game hunting or activities that they would otherwise be unable to enjoy. The platform can be used for securely mounting a wheelchair or a fishing type chair to provide a rotational means for persons with impaired mobility. The turntable is reversibly rotated by an electric motor a full 360 degrees. The motor can be independently actuated by a switch located on the turntable within easy reach of the chair occupant or by a switch at another convenient location.

Guide tracks 56, 56 projecting in a vertical direction are provided in a right and left of a running track 50 and left and right guide rollers 20, 21 are provided on a track guided vehicle and guided using inner surfaces of the left and right guide tracks. Branching rollers 22, 23 each comprising elevating and lowering means are provided in the right and left of the track guided vehicle and outside the right and left guide tracks. Thus, branching and rectilinear progression of the track guided vehicle is controlled by switching between a state where the branching rollers 22, 23 are elevated or lowered to guide the track guided vehicle using outer surfaces of the guide tracks 56, 56 and a state where the branching rollers 22, 23 do not contact with the outer surfaces. Whether the track guided vehicle runs straight or shifts to a branch line can be controlled by contacting one of the branching rollers 22, 23 with the outer surface of the corresponding guide tracks 56, 56, which guide the guide rollers 20, 21 in the section (rectilinear progression section 52) different from the branching portion 51.

A rail system for a powered pallet conveyor, which comprises alternative pathways having an electric cable provided on at least one of n parallel rails defining a travel pathway, wherein n≧2, whereby the rail system includes a switch for switching between m alternative travel pathways, wherein m≧2, and allowing the vehicle to continuously move across the switch after switching, said switch comprising a first actuator for selectively positioning (m*n) rigid rail portions bridging the distance between rail ends at (i) n joining points where the n parallel rails of each of the m alternative travel pathways subject to switching converge, and (ii) (m*n) continuation points where each alternative pathway subject to switching diverges downstream from the joining points. A second actuator selectively positions [m(n−1)] rigid rail portions bridging the distance between rail ends, where each alternative pathway is discontinued downstream from the corresponding continuation points.

A plurality of working blocks (A, B) are connected by rails (18). A branched transporting mechanism (100) is disposed at the intersections of the rails (18). A transportation vehicle (300) of non-self-propelled type moves on the rails (18) by the driving power of a wire (20). A placement table (450) is positioned in the vicinity of the working blocks (A, B). The placement table (450) moves up and down with a workpiece placed thereon between the transportation vehicle (300) and the working blocks (A, B). Transfer of work is effected by moving the placement table (450) up and down, and adjusting the height of the placement table (450) to the height of the transportation vehicle (300) or to the height of the working blocks (A, B). Further, the transportation vehicle (300) has a wire gripping mechanism (350) for gripping the wire (20), and workpiece placement plates (326a, 326b) for placing the workpiece thereon.

The article transport facility includes a plurality of article transport vehicles which can travel on a travel path defined by rails installed in the ceiling. The travel path includes a loop-shaped primary path, and secondary paths each arranged to extend along and by at least one article transport location, a first connecting path that connects the primary path and the secondary path, and a second connecting path, provided independently from the first connecting path, with one end portion connected to the secondary path located on one side of the primary path, and the other end portion connected to the secondary path located on the other side of the primary path.

A circuit board is enclosed in a housing containing rows of metal oxide varistors. Multiple surge ferrule type fuses are soldered directly to circuit board holes between the rows of metal oxide varistors. A ring connector electrically connects pairs of fuses and an electrical conductor connects the ring connector to an electrical circuit to be protected.

A turntable for a heavy object such as a car which includes a ground-engaging member and a load-supporting platform each having load surfaces facing each other, the load-supporting platform being supported off the ground-engaging member by an intermediate load transfer unit comprising a plurality of rotatable bearing elements distributed across an extended region of the load surfaces to allow rotation of the load-supporting platform with respect to the ground-engaging member.

A ground handling system for an airship which comprises a first track system to allow a plurality of docking carts to move from a hangar to a weathervane/launching/landing ring R. The docking carts are configured to complete a second track system. Carried by each of the docking carts is a mooring cart that carries a mooring structure. Upon the completion of the second track system by each of the docking carts, the mooring carts are able to move about the second track system. Thereby allowing the airship to be oriented in a desired manner to facilitate its launch or landing.
