  • Patent number: 6701804
    Abstract: In a power switching apparatus which switches a power transmitting state from a drive member to left and right two driven members, a circumferential connection surface of the drive member and each of circumferential connection surfaces in both of the driven members are wedge connected according to an interposition of rolling elements by moving cages in an axial direction based on a centrifugal force of a switching means. The power switching apparatus also brings end surfaces of the cages into frictional contact with the driven members so as to rotate together therewith.

  • Patent number: 6691889
    Abstract: The invention relates to an arrangement for a fuel tank for heavy vehicles. A middle section, which consists of plastic or aluminum material with an at least essentially identical transcurrent cross section in a horizontal direction viewed in the longitudinal direction, exhibits internal partitions extending horizontally in the longitudinal direction and bulkheads extending across the aforementioned partitions in the longitudinal direction. Pairs of end pieces forming end walls exhibit essentially the same profile as the circumference of the middle section and at least parts of the cross section of the partitions as end pieces which meet one another and middle sections for welding together at the respective ends of the assembled fuel tank. The partitions of the end pieces exhibit recesses forming connecting paths between the various formed sections in the middle section.

  • Patent number: 6667623
    Abstract: A light emitting diode (LED) signal with an LED light output monitoring sensor. If the LED light output drops below a pre-set level, an output signal of the sensor via a comparator and deactivation circuit, deactivates one or more LEDs creating a visible fault display aspect, thereby visually indicating signal failure but allowing a continued use of the signal prior to replacement.

  • Patent number: 6662982
    Abstract: The present invention relates to a device in a load carrier for vehicles, which load carrier is intended for roof-mounting. The load carrier comprises support members intended to rest against the upper face of the vehicle roof close to the edge thereof, a sheet-metal gripping member disposed in the support member to grip the edge portion of the vehicle roof, and a means arranged to lock the support member and the gripping member in a position, in which said means grippingly engages the associated roof edge portion. The gripping member is divided, in a portion of articulation, into at least two parts as seen in the lengthwise extension of the member, said two parts being hingedly interconnected in said portion of articulation in overlapping fashion while being separated by means of a spacer element.

  • Patent number: 6644841
    Abstract: A reflector for use with light emitting devices. Multiple reflective surfaces redirect light emission components of the light emitting device, for example a light emitting diode, into a desired direction. The different light emission components including a total internal reflection light emission component. Paired light emitting devices share common reflector surfaces creating an oval light pattern. Holes in the reflector accommodate electrical components and enhance heat dissipation. A deflector pattern on non-reflector surfaces minimizes sun phantom effect when the reflector is used, for example, in a traffic signal.

  • Patent number: 6642666
    Abstract: A railway searchlight signal uses a printed circuit board populated by three arrays (green, red and yellow) of LEDs. The LEDs are lit by a standard color light power supply unit (PSU). As only one array of LEDs is lit at a time, an interface between the PSU and the LEDs is provided to select which LED array to couple with the PSU. External repeater contacts provide information on which aspect is displayed. This searchlight system design is failsafe in that no single failure of a component will produce a less restrictive aspect.
