  • Patent number: 9801306
    Abstract: The present invention relates generally to a heat sink comprising a plurality of fins, each fin having two or more prongs extending from a root section of the fin. In certain embodiments, the heat sink may be assembled by aligning the plurality of fins within slots between protrusions extending from a base of the heat sink. However, in other embodiments, the plurality of fins may have connector ends having female sides and opposite male sides, wherein the plurality of fins may be attached to each other via the interlocking female and male sides, thereby forming at least part of the base of the heat sink, and fortified with reinforcing members.

  • Patent number: 8325479
    Abstract: The present invention relates generally to tuning the flow of cooling air across converter and inverter heat sinks in a motor drive system. More specifically, present techniques relate to motor drive duct systems having parallel cooling air duct channels dedicated to providing cooling air for a converter heat sink and an inverter heat sink, respectively. In particular, a first duct channel through an inverter duct and a converter duct is dedicated to providing cooling air to the converter heat sink without cooling the inverter heat sink, whereas a second duct channel through the inverter duct and the converter duct is dedicated to providing cooling air to the inverter heat sink without cooling the converter heat sink.

  • Patent number: 8325478
    Abstract: The present disclosure is generally directed to efficiently cooling converter and inverter components of a drive system. Present techniques relate to a motor drive duct system that facilitates efficient cooling and access to motor drive components. The motor drive duct system includes duct channel paths that are parallel and adjacent to one another. The duct system includes a converter section that houses a converter heat sink, an inverter section that houses an inverter heat sink, an exhaust section, and an air inlet section. The converter section and the inverter section are configured to be attached and detached from each other at end sections that are angled to receive one another. Further, the inverter section, converter section, and air inlet section are configured to roll into and out of a cabinet, which facilitates access to field wiring.

  • Publication number: 20120014062
    Abstract: The present invention relates generally to efficiently cooling converter and inverter components of a drive system in accordance with present embodiments. More specifically, present techniques relate to a motor drive duct system that facilitates efficient cooling and access to motor drive components. The motor drive duct system includes duct channel paths that are parallel and adjacent to one another. These channels are formed by various duct segments coupled together or integrated to form the duct system. In particular, the duct system includes a converter section that houses a converter heat sink, an inverter section that houses an inverter heat sink, an exhaust section, and an air inlet section. The air inlet section may include a blower for blowing cooling air through the duct channel paths of the converter and inverter sections. The converter section and the inverter section are configured to be attached and detached from each other at end sections that are angled to receive one another.

  • Patent number: 7721937
    Abstract: A solid weld-metal-producing material is formed by agglomerating weld metal material powder. An igniter may be integrally formed in or on the agglomerated weld metal material. In addition to typical components of a weld metal material mixture, such as a reductant metal and a transition metal oxide, the agglomerated weld metal mixture may include a binder material, such as sodium silicate. In addition to functioning as a binder to help hold the agglomerated weld metal material together, the binder material may aid in the exothermic reaction that occurs when the weld metal material is ignited. The agglomerated weld metal material may be made by mixing together a reductant metal powder, a transition metal oxide powder, and possibly a binder solution. A slurry of the components may be pressed together, for example, using a die and a ram, and then may be dried.

  • Patent number: 7134921
    Abstract: The terminal block assembly of this invention provides a finger safe method of distributing power while at the same time enabling the installer to make uniform and correct connections to a multiplicity of taps or ports. Each connection includes an abutment or seat physically to engage the end of the conductor and in addition the construction of the block and its insulating case provides the installer with visual access to the tip of the conductor in its proper seated position before the conductor is secured to the block with clamp screws. In order to provide such visual access the walls partially blocking the seating end of each conductor socket are scalloped or provided with an inverted conical section which enables the tip of each conductor to be seen from the top of the block. To facilitate this visual access the entire top of the insulating case is made from a transparent material.

  • Patent number: 6966104
    Abstract: A tool for forming a high strength reinforcing bar coupling driving self-locking wedge sleeves over each end of a contractible jaw assembly bridging the abutting ends of the bar to be joined. The sleeves are seated in collars engaged by the distal ends of arms driven for closure by a piston-cylinder power unit and a cam on at least one arm. In one form the cam on one arm is engaged by a roller connected by a tension link to the other arm. In another form cams are provided on each arm driven by rollers fixed with respect to each other. The collars include self-releasing collets seating the sleeves. The tool has other uses such as bar shearing or forming.
