  • Patent number: 10238140
    Abstract: Methods of processing tobacco for the production of an oral tobacco product. According to one embodiment the method comprises providing a base blend of tobacco, delivering a pre-determined quantity of said base blend of tobacco to an individual consumer-portion container and introducing an additive to the tobacco directly in the container. Apparatuses for such methods are also provided.
    Type: Grant

  • Patent number: 6531791
    Abstract: A full float system with Transient Free Multiple Load Disconnection Reconnection (TFMLDR) is disclosed. The system is based on a concept of always connecting loads and dedicated rectifiers together, and then connect such groups (1-n) via power switching devices (C1-Cn) to a pair of busbars. A backup battery is typically connected directly to the busbars via a respective fuse (F114 Fy). The disconnection/reconnection of individual groups to a busbar can then be controlled such that no transients are produced in the system voltage. Such a system is advantageous for reconnection of a load after a disconnection due to a mains power failure. The loads present a substantial input capacitance assisting in stabilizing DC power supply to the load and this load is directly connected to a rectifying unit delivering voltage controlled power during normal mains power operation. After a disconnection of a load from the busbar and the battery by the power switching member, a reconnection will be done in the following order.

  • Patent number: 6382179
    Abstract: A combustion engine with direct injection has in each cylinder a fuel injector (3) whose fuel orifices (4) are so oriented that the projection (5′) of the direction of each fuel spray, viewed in a plane perpendicular to the cylinder centerline, crosses a projection (8′, 8″, 9′, 9″) in the same plane of the valve disc of one of the valves.

  • Patent number: 5381296
    Abstract: A current limiting short-circuiting protector is disclosed which utilizes an electronic and thermal feedback principle for achieving precise and rapid release of the protector, which can be readily reset. The principle utilizes a non-linear powerful temperature-dependent resistor in the collector circuit of a field effect transistor which serves as a current valve and through which the total current to be monitored is passed. The circuit replaces a conventional fuse and may also function as a load on/off control means. When a fault occurs in the load, the erroneous current is limited to a much lower value than is the case with a conventional fuse.
