  • Patent number: 4574655
    Abstract: The present invention provides a wrist mechanism with three degrees of freedom for an industrial robot, which is compactly formed and to which a tool is mounted. The first degree of freedom is associated with a first input shaft for rotating a wrist portion at a low speed. The second and third degrees of freedom are associated with rotating the tool or tilting the wrist. In order to attain these motions, second and third input shafts concentrically arranged relative to the first input shaft are used for transmitting motion to, through bevel gears, speed reduction mechanisms each symmetrically disposed at right and left sides, and the outputs therefrom are used to drive the tool and wrist.

  • Patent number: 4534127
    Abstract: A device for a casting float of the kind through which passes a hole in which the line may run and with a chamber (2) which is open to the front and which forms an extension of the hole (3). This chamber (2) is dimensioned so that it will house the hook with its bait, livebait, flies or similar, and a sinker, where used. A stop which will prevent the line (5) from passing completely through the hole is attached to the line (5) above the float (1,3). A spool (7) is attached to the end of the line. The external dimensions of the spool match the chamber (2) and the spool is designed to be placed inside the chamber before the cast is made. Attached to the spool are one or more snells (16) with fishing-tackle in the form of, for example, a hook (17), flies, livebait or similar. The snells (16) are designed to be wound onto the spool during the cast. The spool may be used as the sinker, being made from a heavy material such as lead.

  • Patent number: 4531342
    Abstract: A cup dispenser for cups containing freshly made beverages comprises a discharge opening connecting a dispensing chamber with the interior of the dispenser. This discharge opening is from the inside filled by a rotor mounted about a vertical shaft. The peripheral wall of the rotor closes completely the discharge opening in any position of the rotor apart from the position in which a recess opposes the discharge opening. This recess is shaped in such a manner that it may receive a cup situated therein when the dispenser is activated. Subsequently, the cup is filled with the desired beverage at a filling station and optionally provided with a cover at a cover dispensing device. Such a dispenser protects the interior parts thereof efficiently against the environment, and furthermore it allows the positioning of the covers on the filled cups in a simple manner.
