  • Publication number: 20050105302
    Abstract: A lamp (10) is disclosed with a single or double-sided socket, whereby a bulb element (11) is arranged on the at least one socket (12), which surrounds a volume of space (14) and said lamp is provided with at least one LED element (13). An irradiation of the LED light into the bulb element occurs and, as a result of reflection, in particular total reflection, on the defining surfaces (16,17) of the bulb element a transmission of the LED light within the bulb element occurs.

  • Patent number: 6751689
    Abstract: An interface circuit transmits data via a serial interface to and from a processor. A first-in-first-out memory is disposed between the serial interface and the processor. A suitable method transmits data which are received and read into the memory serially bit by bit and are read out of it byte by byte by the processor, or, respectively, can be written byte by byte into the memory by the processor and can be transmitted from the memory bit by bit.

  • Patent number: 6502581
    Abstract: The invention relates to a method and device for regulating the output moisture content of tobacco conditioned by a loosening/conditioning and optionally casing (saucing) drum comprising injecting a throughflow of water into the infeed region of the drum by a first nozzle regulated depending on the target value for the tobacco output moisture content and the actual values for the tobacco mass flow, the steam throughflow and the tobacco input moisture content; and injecting a throughflow of water in the outlet region of the drum through a second nozzle, the target value of which is computed depending on the target value and actual value for the tobacco output moisture content.

  • Patent number: 6065363
    Abstract: A change-speed gearbox of a motor vehicle includes a shifting element moveable within a plurality of shift gates for engaging and disengaging a selected gear. A gearshift member cooperates with the gear shifting element. The gearshift member is movable to perform a rotary shift movement and a linear shift movement. A shift device for the gearbox includes a motor having a shaft extending therefrom rotatable about an axis. The gearshift member is axially slidably supported by the motor shaft and rotatably engaged therewith. A solenoid is engaged with the gearshift member for slidably axially moving the gearshift member into a plurality of positions corresponding with the shift gates.

  • Patent number: 6025720
    Abstract: A gradient amplifier for a nuclear magnetic resonance tomography apparatus has at least one control arrangement with a comparator and a controller and a control input for a digital control word, by means of which a current transmission function of the control arrangement can be selected from several predetermined transmission functions. A nuclear magnetic resonance tomography apparatus includes such a gradient amplifier, as well as a control word producing source for producing the digital control words. The gradient amplifier and the tomography apparatus can easily be adjusted to different controller characteristics, without the changeover requiring a manual calibration.

  • Patent number: 5957565
    Abstract: A reflector light has a reflector having a reflective inner surface having an edge defining a ceiling plane and substantially symmetrical to a symmetry plane perpendicular to the ceiling plane and a rear-end compartment bisected by the symmetry plane and remote from the ceiling plane. A lamp or primary light source is provided in the compartment on the symmetry plane. An at least partially light-passing diffuser separate from the reflector and spaced toward the surface from the lamp is substantially symmetrical to the symmetry plane and has a light-emitting flat outer surface directed toward the ceiling plane. The surfaces are shaped such that light emitted by the diffuser surface is reflected by the reflector surface outward in a space symmetrical to the symmetry plane and defined by a family of lines tangenting the reflector edge and traversing the symmetry plane. The diffuser surface lies between the family of lines and the lamp.

  • Patent number: 5385065
    Abstract: A multispeed transmission for motor vehicles includes, rotatably mounted in a gearbox housing (4), an input shaft (1) carrying fixed gear wheels and loose gear wheels, a first driven shaft (2) carrying loose gear wheels and fixed gear wheels and a second driven shaft (3), both the driven shafts (2 and 3) engaging, respectively, via first and second fixed final drive pinion (5 and 6), with a driving gear (7) of a differential (8) that drives front wheel drive shafts by way of constant velocity joints. All gears including the reverse gear are synchronized. The fixed gear wheels (10 and 12) for the first and second gears are carried on the input shaft (1). The loose gear wheels (11 and 13) for the first and second gears, together with their associated synchronizer (21), are carried on the first driven shaft (2).

  • Patent number: 4669617
    Abstract: In a pen holder device, a pen holder body (3) contained in a support body (2) is pivotable between an operational position, which is slightly inclined from the perpendicular, and a generally horizontal readiness position, wherein an acute angle exists between the operational position and the readiness position. Bearing shoulders (15) provided on opposite sides of the pen holder body (3) rest with little friction upon support surfaces (12) having evenly curved surface areas. The center of gravity (21) of the pen holder body (3) alone is below the bearing shoulders (15) and the common center of gravity (20) of the pen holder body (3) and a writing instrument (4) inserted in it is above the bearing shoulders (15).
