  • Patent number: 6688033
    Abstract: An ice fishing device comprising a column member adapted to be supported in an upright position in an ice hole in an operative position, support means are pivotally mounted to the column member, adapted to span an ice hole and support the column member in an upright position. A reel is rotatably mounted to the column member and positioned thereon to be underwater when the column member is in an operative position. A flexible signal mast is attached to the column member at the upper end thereof, and is bendable essentially one hundred eighty degrees to an armed position and will spring upright when released from the armed position. A first bearing bracket is mounted to the column member at a lower position when said column member is in an operative position and a second bearing bracket is mounted to the column member at an upper position above water when said column member is in an operative position.

  • Patent number: 5037354
    Abstract: A mechanism useful as a slip clutch or brake which comprises a housing member having a shaft affixed thereto and extending from one end thereof and a ball at the other end thereof having a second shaft extending therefrom outwardly of the housing. The housing has a partial end wall with an opening therethrough for the second shaft and a friction material having a partially spherical surface in the housing and positioned against the partial end wall. The ball is seated against the partially spherical surface of the friction material and drives the housing therethrough, but will slip when a predetermined torque is exceeded. The ball is biased into engagement with the friction material whereby when one of the shafts is rotated, the other is driven through frictional engagement of the ball and the friction material. Where the mechanism is utilized as a brake, the shaft on the housing may be eliminated.

  • Patent number: 4830833
    Abstract: A catalystic converter includes an annular catalyst bed containing catalyst beads and defined by inner and outer coaxial perforated tubes. An outer shell coaxial with the catalyst bed defines a passage between the outer shell and the outer perforated tube. The passage is connected to an outlet port. Exhaust gas flows radially outward through the catalyst bed and then through the passage to the outlet port. Air is injected into the passage at a selected axial location and is drawn into the catalyst bed by the reciprocating action of the engine. As a result, the single catalyst bed has an inner zone with a scarcity of oxygen which reduces oxides of nitrogen and an outer zone with oxygen present. Unburned hydrocarbons and carbon monoxide are oxidized in the outer zone.
