Abstract: A method of and system for liquefying snow. The system includes a rotor-stator device mounted within a melting reservoir and having a slotted rotor and a slotted stator. Snow and/or ice is deposited in a water bath in the melting reservoir. The rotor rotates at high speed, hurling particles of crystalline snow from the tips of the rotor slots onto the perpendicular faces of the stator, thereby fracturing the crystals and promoting liquefication. The high mechanical forces generated during operation of the rotor-stator device also contribute a significant amount of heat that is applied directly to the snow. The system also includes ancillary assemblies, such as heat-exchangers and snow-transport means. The system is operable as a stationary unit or a mobile unit.

Abstract: A spinning reel rotor braking device has a moving member, a braking member, and a restriction mechanism. The moving member is provided on the rotor and movable between a first position and a second position as the bail arm moves. The braking member is mounted on the mounting groove of the reel unit, and has a drag portion that generates a braking force by frictionally sliding against the moving member when the moving member is in the second position. The restriction mechanism is formed on an inner periphery of the braking member and on an outer periphery of the mounting groove, and restricts backward movement of the braking member relative to the reel unit so that the braking member does not come into contact with a rear end portion of the mounting groove. With the present invention, the braking force of the rotor braking device can be stabilized.

Abstract: The invention compensates or normalizes for the non-linear oscillation speed of the spool in a fishing reel through use of a special shaped guide slot. The guide slot can be shaped through combining a number of curves into the length of the slot. In particular, for each end of the guide slot there is contained a curvature section, such that both ends of the guide slot are curving toward the spool side in one design or away from the spool in the other design. This general shape of the guide slot improves the contact position between the pole and the level wind bracket, and also compensates for the non-linear speed of the spool. The shape of the guide slot also reduces the wobbling or jiggling that occurs during operation of the reel when compared to conventionally designed reels.

The first sound producing portion is mounted to the spool shaft so as to be unrotatable when the spool rotates in a line releasing direction and rotatable when the spool rotates in a line winding direction. The pawl member is urged toward the saw tooth portions by a spring member. The spinning reel sound producing mechanism produces sound only when the spool rotates in the line releasing direction.
