  • Patent number: 10625383
    Abstract: A mounting device for mounting a machine tool to a floor area is provided. The mounting device includes mounting units that are attachable to the machine tool. Counter-mounting units are disposed on the floor area. The mounting device may also include electromagnets that are disposed on either the mounting units or the counter-mounting units. The machine tool can be mounted or removed by switching the electromagnets on and off. When one of the mounting units or the counter-mounting units includes the electromagnets, the other may include a ferromagnetic material.

  • Patent number: 8910795
    Abstract: A magnetic separator comprising a vibratory conveyor for vibratorily flowing non-ferrous articles and articles containing ferrous material within the magnetic field of a transverse extending magnet to magnetically capture the articles containing the ferrous material while allowing the non-ferrous articles to flow therepast. The magnet is periodically retractable to remove ferrous articles magnetically adhered thereto. The use of a set of transverse extending magnets enables a continuous on-the-go separation of articles containing ferrous material from non-ferrous articles without having to shut down the vibratory conveyor.

  • Patent number: 7320029
    Abstract: The invention relates to a device, system and method a method for applying a certain Quality of Service (QoS) to a data stream (31a–31c, 32a–32b, 33a) of an application (31–33) communicating data over a sockets connection. The method comprises providing a uniquely identifiable identifier (UID, Stream Type) the application (31–33) or to the data stream (31a–31c, 32a–32b, 33a) from or to the application, and associating said identifier (UID, Stream Type) with a particular QoS in order to apply the particular QoS to the particular application (31–33) or to the particular data stream (31a–31c, 32a–32b, 33a), which application or data stream is identified by the identifier.

  • Publication number: 20020027095
    Abstract: A method and an apparatus for classifying and recovering the main components of used batteries, particularly, a method and an apparatus by which the batteries are conveyed on a conveyor while an alternating magnetic field of a plurality of frequencies is applied to each and a detection means detects what sort of induced magnetic field has resulted from the eddy current induced in the battery. The orthogonal components in the change of the induced magnetic field are detected; the relationship between these orthogonal components and the frequencies are compared with the database of the same which is previously obtained, and the batteries are sorted according to their classification and size. This method can sort large amounts of used batteries continuously. In this invention, the battery will be drawn down into the detection region either magnetically or mechanically while the stable transport of the battery is achieved.

  • Patent number: 6260168
    Abstract: A method and system for performing optional or selective forward error correction (FEC) on data within the data link layer before the data is transmitted. First, a determination is made as to what data in the data link layer requires to be FEC encoded. Next, the data link layer data determined to require FEC encoding is protected by FEC and the remaining data link layer data is not FEC protected. A data application or any network protocol layer above the data link layer determines the portions required to be FEC encoded.

  • Patent number: 5797498
    Abstract: A magnetic separator for separating a magnetic substance such as metal parts or workpieces from a nonmagnetic substance such as abrasives used in a barrel finishing includes an infeed passage along which a mixture of the workpieces and the abrasives is conveyed. A rotary drum is rotated in a direction crossing the infeed passage, and a magnet is mounted in the rotary drum so that the magnetic substance is attracted to a circumferential surface of the rotary drum. The workpieces picked up onto the rotary drum are conveyed along an outfeed package, and a demagnetizer establishes an alternating field in the middle of the outfeed passage along a direction in which the magnetic substance is conveyed along the outfeed passage. A sweeping brush is located on the infeed passage in the vicinity of the rotary drum so as to scrape the surface of the workpieces attracted to the surface of the rotary drum to sweep off granular abrasives adherent to the surface of the workpieces.

  • Patent number: 4451360
    Abstract: An apparatus for removing adherent magnetically attracted particles from the surface of the magnetic head pulley of the conveyor belt used in a dry magnetic separator without disrupting the magnetic separation process. An array of magnetically soft iron tines of several sizes is provided to be moved into and out of close proximity with and substantially normal to the magnetic head pulley surface. When in proximity to the magnetic head pulley, the soft iron tines are induced with a magnetic force and because of their shape, a magnetic field gradient is formed in the direction of the tines having a force sufficient to attract the particles from the head pulley to the tines. When the tines are moved away from proximity with the head pulley, they lose most of their induced magnetism and the attracted particles fall into a discharge chute or collection box.

  • Patent number: 4354930
    Abstract: A device for separating a mixture material into a magnetic material, a nonmagnetic conductive material and a nonmagnetic nonconductive material. The device comprises a drum revolving in one direction about a longitudinal central axis thereof. The magnetic material of the mixture material thrown into the drum is attracted to the inner peripheral surface of the drum by the magnetism of a magnetic field surrounding the drum and rotating in a reverse direction to a direction of rotation of the drum, and released from the inner peripheral surface of the drum in a predetermined rotational region in the drum, thereby being received on a receiving member. The nonmagnetic nonconductive material is directed in the direction of rotation of the drum along the inner peripheral surface of the drum, and the nonmagnetic conductive material is directed in a reverse direction to the direction of rotation of the drum by the electromagnetic force of the rotating magnetic field.
