Abstract: A hinged toilet seat and cover assembly has at least two magnetic latches positioned to control the movement of the seat and cover. A first magnetic latch positioned between the hinge and cover serves to hold the cover in a vertical position once the cover has been raised to such position. A second magnetic latch positioned between the cover and seat at a point spaced from the hinge serves to hold the cover and seat in contact with each other once they are brought into such contact.

Abstract: A fishing line release mechanism has a permanent magnet positioned within a housing with the poles of the magnet arranged to draw a magnetic release plate toward, or into contact with, the magnet. The release plate has a buttonlike configuration with a central aperture which enables the plate to be threaded by a fishline. When a fishline threaded through the magnetic plate aperture is looped several times around the plate and the plate is then positioned in proximity to the permanent magnet, the line cannot unreel until considerable tension is applied to it. The tension limit can be preset. When the preset limit is reached, the buttonlike magnetic plate springs away from the permanent magnet to release the fishline to further control by the reel.

Abstract: A fishing line release mechanism has a permanent magnet positioned within a housing with the poles of the magnet arranged to draw a magnetic tripping member into the housing through an opening in which the tripping member is positioned. The tripping member includes at least one belaying pin which is arranged with its axis across the opening in the housing when the member is in a position where it is near, or in contact with, the permanent magnet. When sufficient tension is applied to a fishing line wrapped around the belaying pin at the time the tripping member is closest to the permanent magnet, the member is pulled away from the magnet and the axis of the belaying pin is lined up with the direction of pull of the fishing line to release the line over the free end of the pin. The release mechanism may include means for variably positioning the magnet with respect to the tripping member as well as a line guide through which a line may be drawn to the belaying pin or pins.
