  • Patent number: 6189301
    Abstract: A form-fill-seal packaging machine has a halting device above its transverse sealer below a cylindrical chute through which articles to be packaged are dropped cyclically in batches. A film is bent into a tubular form and pulled down around the chute to the transverse sealer. The halting device serves to squeeze the film such that the free-falling articles are temporarily halted before reaching the transverse sealer such that the articles can pass through the transverse sealer in a more compactly bunched batches. This makes it less likely for any of the articles to be caught between sealing devices of the transverse sealer and the work efficiency of the packaging machine can be improved.

  • Patent number: 6189304
    Abstract: A zero turning radius power lawn mower for operation by a standing occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero radius turning of the mower about a central turning point. The riding platform is positioned near this turning point or axis so that the standing occupant remains substantially unaffected by centrifugal force created during approximate zero radius turning of the mower thereby allowing the mower to take such turns at higher speeds. The low center of gravity created by the position of the riding platform for the standing operator also results in the mower having improved traction and being less likely to pop “wheelies” upon acceleration.

  • Patent number: 6189310
    Abstract: A gas turbine power system for generating energy by means of a gas turbine cycle, wherein heat energy is more effectively used by burning the exhaust gases (109) and the partial oxidation of said exhaust gases (109) is achieved by means of a hypostoichiometric amount of air and steam fed into a catalytic reactor (107) to form a first oxidation stage followed downstream in said turbine (103) by additional oxidation occurring in a power turbine (104) or downstream therefrom, said power turbine being in turn arranged downstream from the catalytic reactor (107). Catalytic partial oxidation may be performed using a supply of an initiating agent, particularly hydrogen. The method is remarkable in that the hydrogen fed into the reactor inlet through an injector (113) is provided by recycling part of the effluent from the reactor, the power turbine or a reforming reactor for reforming part of the fuel gas with a large excess amount of steam for performing catalytic partial oxidation.
