  • Publication number: 20190178267
    Abstract: An assembly is for filling a gas tank for a combustion engine from a gas-filled storage bottle via a filling device arranged between the tank and the storage bottle. The tank has at least one fill valve for liquefied gas, a pressure relief valve for gas in the gaseous state, and an extraction valve for liquefied gas. The filling device has a gas connection for the storage bottle and has a fill connection for the fill valve. For filling the tank, the fill valve is connected via the filling device to the storage bottle, such that, when the fill valve is open, liquefied gas flows from the storage bottle via the fill valve into the tank. During the inflow of liquefied gas, the pressure relief valve of the tank is at least intermittently open. A filling level gauge is provided for indicating a predefined filling level in the tank.

  • Patent number: 6293504
    Abstract: A tube holder, particularly for holding a protective tube for cables on a robot, with two mutually articulated half-shells closable by a lever provided with a spring clip, is characterized in that on either side of the lever are formed radially extending protective ribs, which cover the circumferential contour of the lever in the closed position thereof

  • Patent number: 6288512
    Abstract: A robot has a plurality of components which can pivot relative to each other, in particular robot arms. Changes in separation between individual points of the robot thereby occur. This must be taken into consideration when guiding the operation cables for robot elements and in particular robot tools. The cables must be capable of accommodating length changes while being loaded to as little extent as possible during motion of the robot so that they have high durability and are not prematurely damaged. In accordance with the invention, a robot having cables extending at least partially on the outside, in particular operation cables for robot tools such as a welding tool, has cables guided in a substantially circular loop at the height of a robot arm which can pivot about an axis of the robot.

  • Patent number: 6244506
    Abstract: A description is given of a method of extending the period of validity of smart cards, without the cards having to be surrendered by their owner. For this purpose, use is made of reading/writing devices which are installed near smart card users and, by extension passwords sent to the owner by a central issuing agency, extend the date of validity of the smart card.

  • Patent number: 6082622
    Abstract: A system and method of storing and preparing data uses at least one data memory card having at least one electronic memory chip and a separate optical memory. At frequent intervals alphanumeric data is entered into the at least one electronic memory chip. At less frequent intervals, image data is entered into the optical memory, data is read from the at least one electronic memory chip and data is transferred from the at least one electronic memory chip into the optical memory.

  • Patent number: 4705243
    Abstract: To supply the implement, mostly a welding tool, of a manipulator (1), with energy, the invention, instead of running the supply lines in the known manner from a fixed point in a large, freely suspended loop directly to the tool, provides an external suspension of a line bundle (10) along the constructional assemblies of the manipulator. In accordance with the invention, this line bundle (10) is held in place and guided in tubular casings (13) which are disposed at the individual assemblies (3-5) of the manipulator (1), with inserts (19) being provided in these casings (13) for receiving and holding lines of unequal size (parallel with each other) which are adapted to the various functions of the manipulator and can quickly be exchanged.

  • Patent number: 4133511
    Abstract: In the disclosed system a motor axially displaces a screw-threaded movable valve member by rotating it within an interiorly threaded collar. A sensor detects the movable valve member's axial position. An electrical feed-back circuit compares the sensor output with a reference value and drives the motor accordingly. In one embodiment the motor possesses a disc rotor and in another embodiment a moving coil rotor. In each case the stator links the rotor conductors which extend radially from the rotor center.

  • Patent number: 4025934
    Abstract: A method and device is disclosed whereby the number of revolutions of an axle or the angle of rotation of an axle are represented by a particular value. The value is preferably in the form of an electric analog signal. A pickoff element having a linearly-shaped primary coil and a linearly-shaped secondary coil is disposed so that the primary and secondary coils are in parallel with an air gap therebetween. The air gap is for the formation of a homogeneous stray field. A metallic disc which has a rim in the form of an Archimedes' spiral, is affixed to an axle. The disc is disposed in the air gap between the primary and secondary coils. A high frequency signal is supplied to the primary coil. Accordingly, when the axis is rotated, an amplitude modulated signal is developed at the secondary coil. The amplitude modulated signal is then demodulated and subsequently differentiated to provide an analog signal proportional to the angular rotation of the axle or the number of revolutions of the axle.
