  • Extruded housing with hinged lens for LEDs
    Patent number: 9004717
    Abstract: An extruded housing using a single polymeric material to form an opaque body portion that defines an open channel, a light transmitting lens portion, and a hinge portion joining the body portion to the lens portion to form a unitary body. The hinge portion allows the lens portion to pivot relative to the body portion between an open position, where the channel is open, and a closed position, wherein the lens closes the open channel. The extruded housing is designed to form part of a light emitting diode light fixture, where the housing accepts a strip or plurality of LEDs within the channel for emission of light through the lens portion.

  • Method and apparatus for cutting tire ply stock
    Patent number: 6928911
    Abstract: Method and apparatus for severing tire ply stock (S) wherein the apparatus includes a knife assembly (14) utilizing a blade (50) having a curved leading edge (58) and a straight trailing edge (62) which meet at a leading point (66). The ply stock (S) is supported by a slotted anvil (26) in the area immediately adjacent a cut line. In operation, the knife assembly (14) is lowered and the leading point (66) pierces the ply stock (S) between adjacent cords. During the downward stroke, the trailing edge (62) back-cuts the ply stock (S) from the insertion point (98) to a first lateral edge (18). The leading edge (58) severs the remainder of the ply stocks (S) as the knife assembly (14) traverses the ply stock to a second lateral edge (22).
