  • Publication number: 20040104659
    Abstract: The invention facilitates insertion of fluorescent semilamps for retrofitting of existing fluorescent lamps with inductive ballasts to electronic high-frequency ballast operation. The pin bases of the semilamps are designed to be separably rotatable as opposed to the previously rigid pin base assembly. The rotatable pin base allows easy insertion of the new semilamps into existing lamps, with only the pin base being rotated to secure the semilamps in their sockets. The semilamp may further provide a grip to aid in the rotation of the pin base, locking snaps to secure the rotatable pin base, or length equalization between different types of fluorescent lamps by addition of an expansion shoulder to the pin base.

  • Patent number: 6743041
    Abstract: The invention pertains to an adaptor for inserting lamps with pin bases into screw bases, the task of which is to make it impossible to screw out the adaptor without special tools after it has been inserted into the screw base. This task is achieved by the invention by arranging the thread of the adaptor on a loosely rotating threaded bushing which can be rigidly connected with the adaptor body by means of a key before screwing in the adaptor. After the adaptor has been screwed in and the key has been removed, the threaded bushing cannot be removed from the socket.

  • Publication number: 20030228801
    Abstract: A low-profile lamp socket which can be used for conventional incandescent lamps, but which is especially adapted for energy-saving lamps which have an integrated ballast. The socket has a central housing with electrical contacts, surrounded by a protective collar. The electrical contacts are interconnected to clamps which are arranged annularly around the contacts, outside of the protective collar. The resultant structure is shorter than conventional sockets and is also safer in that the risk of electrical shock during bulb insertion and removal is lessened.

  • Patent number: 6624617
    Abstract: The method for stabilizing the voltage of an AC generator with varying (alternating) rotor speed is characterized in that the voltage generated by an AC generator is maintained constant when the rotor speed changes. The control is carried out without the use of electrical contacts by means of a high-frequency pulse generator. The transformer of the high-frequency pulse generator is divided. The rotating part is provided on the rotor axis and the other part is stationary outside the rotor. Both parts are separated by an air gap. Deviations from a preset output voltage are controlling the pulse generator whose pulses are transmitted by the transformer to the power section of the rotor. The complete power section consisting of the coil and the electronic switch is arranged on the rotor so as to transmit only control currents without physical contact.

  • Patent number: 6490176
    Abstract: A DC/AC converter is provided for contactless, inductive transfer of energy, which transfers arbitrary voltages to a removable user with the aid of a high-frequency pulse generator. The pulse generator produces asymmetric pulses, which provides two different voltages to the user, depending on a to coupling orientation. Further, the pulse generator is built in such a way that, if a user is absent, it is not excited to oscillation and, as a result, uses substantially no energy at all in a stand-by operation.

  • Patent number: 6429590
    Abstract: A fluorescent lamp having electrical conduits on the outer surface of the gas discharge vessel. Electrical power is supplied to one end of the fluorescent tube, via a ballast assembly which is connected to a first electrode in the tube. The electrical conduits on the outer surface of the tube carry power to the electrode at the other end of the tube, thus eliminating the need for wiring within the tube mounting assembly.

  • Patent number: 6307316
    Abstract: The invention concerns a construction kit system for fluorescent lamps (1) with separate choke unit. Standard low-power modules which are cheap and easy to manufacture can in particular be plugged in any combinations into choke units fitted as compact lights or in lamp housings. A number of examples are given to show the new possibilities for constructing lighting systems. These fluorescent lamps each have a replaceable light element comprising at least one gas discharge vessel (1) with a base at one end as the light element and at least one choke unit (6) in the form of a separate unit fitted in a housing and capable of electrical connection via plug connectors (2) to the light element. The light element is designed as a standard low-power module with a glass tube diameter of the gas discharge vessel of no more than 13 mm, thus allowing it to be plugged into different housings individually or in groups.

  • Patent number: 6303004
    Abstract: Stock inlet of a paper machine that includes at least one stock suspension supply, a diffusor block having a plurality of tubular elements, dividing elements which extend across a width of the machine, and a stock inlet aperture having a top wall and a bottom wall. The dividing elements are located between the top wall and the bottom wall, so that a plurality of suspension conduits are formed, which extend across the width of the machine. Further, the stock inlet aperture is positioned one of adjacent one wire and between two wires. The suspension conduits include a first region and a second region disposed downstream of the first region, with respect to a stock flow direction. The first region is formed by flat boundary surfaces which extend across the width of the machine and converge in the stock flow direction, and each of the dividing elements has a sharper convergence of surfaces in the second region than in the first region.
