Abstract: Ionization systems configured with a catalyst-bearing sleeve provide improved filtration while keeping ozone levels within acceptable limits. Modular configurations provide for serviceability and replaceability. System controls monitor particulates, temperature, humidity, and other relevant factors and adjust an ionization level accordingly for optimal performance.

Abstract: In an automotive plug ignition coil core system and method, a first core is formed of stacked laminations each of which comprises a segmented lamination strip folded around to create an enclosed loop shape. Each strip has four segments and a hinge web is provided between first and second, second and third, and third and fourth segments. A grain direction of electrical steel runs lengthwise in each of the segments. A second core inside of the closed loop first core is formed of a plurality of stacked laminations, each lamination having a grain direction of electrical steel running lengthwise.

Abstract: In a lamination core, a punched material strip is wound to provide layers of the core. The material strip comprises a plurality of semi-circle individual strip segments linked by hinge-like carrying webs between adjacent split lines at adjacent ends of the respective adjacent strip segments. Each strip segment has a plurality of teeth defining slots. A segment arc angle of the segment is not equally divisible into 360° and a slot arc angle of the slots is equally divisible into the segment arc angle, so that mated lines of one winding defined by respective adjacent split lines of adjacent are laterally offset with respect to mated lines defined by respective adjacent split lines of an adjacent winding.

Abstract: In a method for manufacturing pencil cores a continuous strip of electrical steel is provided. The continuous strip is cut to create a plurality of starting strips as laminations each having a length longer than a desired length of the pencil cores and at least one of the strips having a strip width at least equal to or larger than a desired diameter of a cross-section of the pencil cores. The starting strips are provided with a bonding layer. The starting strips are stacked and then heated and cured to create a bonded stack. The bonded stack is machined to a substantially circular cross-section. Without a de-burring or de-smearing operation after the machining, the machined bonded stack is cut to create a plurality of pencil cores of the desired length. The pencil cores created by the method are substantially round, and have no welds at end faces.

Abstract: In a method for manufacturing a lamination for a motor or generator where a plurality of the laminations are used to form a core of the motor or generator, a material strip of electrical steel is provided having a width substantially corresponding to half of an outer diameter of the lamination to be created. Slant cuts are made along the material strip to form trapezoids of substantially a same area. Two of the trapezoids are joined together along a side edge of each to form a hexagon. The lamination is then stamped from the hexagon.

Abstract: In a pencil core having a substantially circular cross-section, a stack of laminations are bonded together with bonding layers on each lamination which is heated and cured. The bonded stack has no embossments, has no cutouts forming channels at end faces, and also has no welds at end faces of the pencil core to hold the laminations together. The pencil core has a substantially circular cross-section.

Abstract: In a method for manufacturing a lamination for a motor or generator where the lamination is used as a stator or a rotor of a core of the motor or generator, material strip of electrical steel is provided having a width substantially corresponding to an outer diameter of the lamination to be created. Slant cuts are made along the material strip to form trapezoids of a substantially same area. Two of the trapezoids are joined together along a side edge to form a hexagon.

Abstract: For manufacturing a straight strip lamination, a die is provided having at least a main slot punch and a part feature punch. The strip is fed into the die station with a constant slot step distance progression with the slot punch activated to create a plurality of slots. When a part feature is to be punched, the slot punch is deactivated, the part feature punch is activated, and the strip is fed with a new step distance, which is different than the slot distance.

Abstract: In a method and apparatus for rotating loose laminations in a loose lamination die, a strip is fed through the die to a rotatable blanking chamber of a blanking station. There, a punch engages with a die ring to punch a lamination free from the strip. The rotatable blanking chamber is biased in an upwardly direction. When the punch is not engaging with the die ring, the rotatable chamber is in an upward position wherein a gap develops between laminations retained at a bottom of the rotatable chamber, and those laminations lying directly below the rotatable chamber. The rotatable chamber can then be rotated without damage to the laminations at the gap because of the presence of the gap. Thereafter, a succeeding lamination can be punched after the rotation has occurred. As the punch engages the strip on top of the die ring, the rotatable chamber is pushed downwardly so that the gap at the bottom of the rotatable chamber disappears.

Abstract: This cleaning device utilizes two methods, simultaneously, to remove deposits from the conduction channel inside a multitude of various shaped tubes or the like, including round, square, and rectangular chimney flues. The first removes soft, brittle deposits and the second removes hard, glazed deposits through the use of chisel-like edges (35) and file-like grooved rasping surfaces (34) that are integrated in one element, the raspers (30). Raspers (30) can be replaced when dull. This device is well suited for removing creosote deposits from chimney flues; it can go past unyielding obstructions commonly found in chimney flues, and it cleans all surfaces in a section of flue simultaneously.
