| 20080223693 | ARRANGEMENT FOR MOVING A CARRIER IN A CHAMBER, IN PARTICULAR A VACUUM CHAMBER - An arrangement for moving a carrier within a vacuum chamber is described. This carrier is formed in the shape of a plate and is supported with its narrow-side lower edge on rollers driven by a drive system. As a drive system uses a magnetic coupling which is disposed partially within the vacuum chamber and partially outside of the vacuum chamber. With the aid of a force acting in the vertical direction the two components of the magnetic coupling can be displaced relative to one another. In addition, horizontal displacement of the carrier is also possible. | 09-18-2008 |
| 20090107806 | THREE-DIMENSIONAL MOTION USING SINGLE-PATHWAY BASED ACTUATORS - The invention provides novel mechanisms and methods for effecting rotational and translational motion in three dimensions of objects carried by, or coupled to, actuators that move along a pathway. Vehicles or other conveyances (collectively, “vehicles”) that utilize mechanisms and methods can increase the performance of and decrease the cost of transportation, shipping, manufacturing, materials handling and other systems. In one aspect, the illustrated embodiment provides such a vehicle or other conveyance having two (or more) actuators adapted for movement along a pathway. The actuators are propelled or otherwise capable of motion, relative to each other so that the distance between can be increased or decreased. When desired, that distance can also be maintained the same, e.g., regardless of whether the actuators are moving. A pallet, carriage or other moveable part (collectively, pallet) is moveably coupled to the actuators so that at least selected motions by the actuators relative to one another on the pathway effect rotational and/or translational motion of the pallet in three dimensions relative to the pathway, including, for example, movement transverse to the pathway and out of a plane of the pathway. | 04-30-2009 |
| 20100059339 | TRANSFER APPARATUS WITH DYNAMICALLY VARIABLE DRIVE ZONES - A transfer apparatus includes a primary part, and at least one first and one second secondary part, which are each magnetically coupled to the primary part for drive purposes. A regulation device is provided for regulation of a drive of the secondary parts. The regulation device can regulate the drive of the first secondary part in a first zone of the primary part in accordance with a first regulation rule, and can regulate the drive of the second secondary part in a second zone of the primary part in accordance with a second regulation rule. The first and second regulation rules differ hereby from one another. The first zone is separated from the second zone by a boundary which can be varied dynamically by the regulation device. | 03-11-2010 |
| 20100108469 | MOVING DEVICE - A moving device comprises at least a first element which is movable in a direction of movement by means of a drive unit, which first element at least comprises at least one first magnetic part. The moving device further comprises a second element, with respect to which the first element is movable at least from at least one operative position spaced from the second element to a rest position near the second element. The second element comprises at least one second magnetic part, which is polarized in a polarization direction opposed to the polarization direction of the first magnetic part. The polarization directions extend transversely to the direction of movement and also transversely to surfaces of the first and second elements that are positioned opposite each other in the rest position. | 05-06-2010 |
| 20100175967 | SORTING SYSTEM WITH LINEAR SYNCHRONOUS MOTOR DRIVE - The present invention relates to a sorting system including a conveyor comprising a plurality of carts for carrying articles, in particular for sorting 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. It is an object of the present invention to provide an improved sorting system as well as to provide a sorting system with improved energy utilisation and efficiency. Reaction elements are mounted on each of the carts. The reaction elements each comprise an uneven number of permanent magnets arranged on a plate-like carrier. The magnets on reaction elements of adjacent carts are arranged to form arrow of magnets with constant pitch and alternating polarity said row having an interruption situated at a transition between adjacent carts. A maximum number of coils in the stator may thereby be active at the same time, when driving the conveyor. | 07-15-2010 |
| 20130126307 | CONVEYING DEVICE - A conveying device for moving a carrying plate includes a pulling mechanism in the form of a belt. To pull the carrying plate, the belt is contacted against the carrying plate via a magnetic force of at least one permanent magnet. The carrying plate is then entrained by the belt as a result of static friction or sliding friction. | 05-23-2013 |
| 20130126308 | SYSTEM FOR CHANNELLING AND UNLOADING HOT-ROLLED MATERIALS - A system for channeling and unloading hot-rolled materials downstream of a unit for cutting to size and upstream of a cooling bed, includes feeding a rolled material at high speed inside at least one channeling unit and unloading the rolled material with the channeling unit onto the cooling bed. The channeling unit has a supporting structure with at least one travel channel which is open downwards and with which at least one electromagnet element is associated. Preferably, the at least one travel channel is shaped in the manner of an inverted U. Preferably, the system has at least one pair of adjacent and parallel travel channels. | 05-23-2013 |
| 20140110224 | ELECTRIC ACTUATOR - Provided is an electric actuator capable of preventing the release of particles from the body thereof. The electric actuator includes a body made of an elongated enclosure; a slider configured to move in a reciprocating manner along a lengthwise direction of the body; an opening formed in a side surface of the body to correspond to a moving path of the slider; a dust seal band provided to cover the opening; and a pair of electrodes protruding from the body at opposite sides of the opening toward the outside of the body and extending in the lengthwise direction of the body with the opening being interposed between the pair of electrodes. Positive potential is generated in the upper electrode of the pair of electrodes and negative potential is generated in the lower electrode of the pair of electrodes. | 04-24-2014 |
