  • Publication number: 20250001555
    Abstract: Apparatus (10) for cutting a fishing a fishing line comprises a first lever (12) pivotally coupled to a second lever (14) to define opposed jaws (16, 17) and corresponding handles (18, 19) for opening and closing the opposed jaws (16, 17) by relative rotation of the corresponding handles (18, 19) about a pivot axis (20). Each of the first and second levers (12, 14) comprises a respective lever body (24, 26) and a respective cutting member (30, 31). Each cutting member (30, 31) has at least one open-ended channel (32), with a cutting edge (34) at one end of the or each open-ended channel (32). Each cutting member (30, 31) is a discrete component which is formed of a harder material than the lever body (24, 26) of each lever (12, 14).

  • Publication number: 20240375256
    Abstract: Apparatus (10) for opening a split ring comprises a pair of levers (12, 14) which are pivotally coupled together and define a first jaw (20) and an opposing second jaw (22). A member (30) is mounted on the first jaw (20). The member (30) has a wedge-shaped profile, tapering from a base region (32) adjacent the first jaw (20) to a tip region (34) spaced from the base region (32). The tip region (34) is configured for insertion between adjacent helical turns of a split ring when gripped between the first and second jaws (20, 22). The tip region (34) has an arcuate peripheral edge (36) that extends at least partially around a longitudinal axis (38) of the first jaw (20).

  • Patent number: 7810955
    Abstract: A linear LED light module and system includes a heat sink, a printed circuit board, a plurality of LEDs, a power supply housing, a flexible electrical conductor, a first electrical connector, a second electrical connector, and a power supply. The heat sink is elongated in an axial direction along a longitudinal axis that is parallel with a greatest dimension of the heat sink. The PCB is in thermal communication with the heat sink and includes circuitry. The plurality of LEDs mount to the PCB and are in electrical communication with the circuitry of the PCB. The power supply housing connects to the heat sink. The flexible electrical conductor includes at least two wires that are configured to accommodate an AC line voltage of at least 120 VAC. The first electrical connector is at a first end of the electrical conductor. The second electrical connector is at a second end of the electrical conductor.

  • Publication number: 20070236956
    Abstract: At least two light emitting diodes emit a non-parallel light beam. A condensing system, operationally coupled with the light emitting diodes, receives the emitted non-parallel light beam and converts the received non-parallel light beam into a parallel light beam. A non-imaging concentrator includes an input surface which collects the parallel light beam, and an output surface, which includes phosphor material and outputs light.

  • Publication number: 20060071329
    Abstract: In a chip package (10, 10?, 110, 210), first and second electrical power buses (14, 14?, 16, 16?, 114, 116, 214, 216) are each formed of an electrical conductor having a chip bonding portion (20, 22, 120, 122, 220, 222) and a lead portion (26, 26?, 28, 28?, 126, 128, 226, 228) extending away from the chip bonding portion. The chip bonding portions of the first and second electrical power buses have edges (32, 34, 132, 134, 232, 234) spaced apart from one another to define an extended electrical isolation gap (40, 140, 240). A plurality of chips (42, 44, 46, 142, 143, 144, 145, 146, 147, 148, 242) straddle the extended electrical isolation gap and are electrically connected with the first and second electrical power buses to receive electrical power from the first and second electrical power buses.
