  • Patent number: 8297608
    Abstract: A transport system for conveying sheet material along a feed path. The transport system includes an electro-dynamic propulsion system for moving sheet material, or a stacked collation of sheet material, along a support deck which defines the feed path. More specifically, the electro-dynamic propulsion system includes at least one guideway and a ferromagnetic element disposed internally of the guideway. The guideway includes a magnetic coil to produce a variable magnetic field. By varying the flux density and polarity of the magnetic field the ferromagnetic element may be propelled within the guideway. An abutment member is coupled to the ferromagnetic element, extends through the elongate opening of the support deck and engages an edge of sheet material. A processor is operative to control the electro-dynamic propulsion system and, accordingly, the rate of travel and position of the sheet material along the feed path.

  • Publication number: 20120186948
    Abstract: An object of the invention is to provide a food and drink conveying device that can allow a travel body to travel stably over a travel path. A food and drink conveying device (1) can allow a travel body (7) to travel over a travel path (1a) using a magnetic force between a first magnetic body (18) and a second magnetic body (19) by driving a conveyor driving body (15) and is provided with a lift preventing means (34) in close proximity to the second magnetic body (19), where the lift preventing means (34) makes contact with the travel path (1a) so as to prevent the second magnetic body (19) from lifting due to the magnetic force between the first magnetic body and the second magnetic body (19) and moves together with the conveyor driving body (15).

  • Patent number: 8210343
    Abstract: The invention is a sorting system including a conveyor comprising a plurality of carts for carrying articles, such as parcels and baggage. The conveyor has a linear synchronous motor drive system with stators arranged along a track which the carts follow. Reaction elements are mounted on each of the carts and comprise an uneven number of permanent magnets arranged on a carrier plate. The magnets on the reaction elements of adjacent carts are arranged to form a row of magnets with constant pitch and alternating polarity. The row of magnets has an interruption situated at a transition between adjacent carts.

    Abstract: Provided herein are methods, apparatuses and systems for fabricating photovoltaic cells and modules. In certain embodiments, the methods, apparatuses and systems involve coating ferromagnetic substrates with thin film solar cell materials and using magnetic force to constrain, move or otherwise manipulate partially fabricated cells or modules. According to various embodiments, the methods, apparatuses and systems provide magnetically actuated handling throughout a photovoltaic cell or module fabrication process, from forming photovoltaic cell layers on a substrate to packaging the module for transport and installation. The magnetically manipulated processing provides advantages over conventional photovoltaic module processing operations, including fewer mechanical components, greater control over placement and tolerances, and ease of handling. As a result, the methods, apparatuses and systems provide highly efficient, low maintenance photovoltaic module fabrication processes.
