Abstract: Each of a flange and an end cap have at least two magnets or magnetic pieces arranged in complementary fashion to removably attached the end cap to the flange. The end cap removably seals an orifice of the flange by magnetic attraction between the at least two magnets or magnetic pieces of the end cap and the at least two magnets or magnetic pieces of the flange. This seal between the end cap and flange provides for pressure relief as pressure from within the orifice exceeds the force of magnetic attraction between the magnets or magnetic pieces of the end cap and the magnets or magnetic pieces of the flange.

Abstract: A device and method for connecting a cup and a lid includes a cup portion that has a lip, the lip extending from an outer circumference of the cup portion at an open end of the cup portion. The device has a lid portion and a collar portion. The collar portion engages with the lip, thereby holding the collar portion to the cup portion. A series of magnets and/or metal pieces couple magnetically attract the lid portion to the collar portion. As pressure within the cup portion increases beyond a predetermined point, the series of magnets and/or metal pieces partially disengage, thereby allowing escape of excess pressure.

Abstract: A device and method for coupling two or more objects together has a coupling that has at least two magnets or metal pieces and is removably attached to a first object. A second object has at least two corresponding metal pieces or magnets, wherein the first object and the second object are held together by magnetically attractive forces when the first object and the second object are engaged.

Abstract: An article and method for coupling two or more objects together uses magnetically attractive forces generated by corresponding magnet(s) and/or metal piece(s) positioned at or near the periphery of the two or more objects. Multiple magnet(s) and/or metal piece(s) are spaced-apart around the periphery of the two or more objects. Alternatively, two corresponding annular magnet(s) and/or pieces of metal are used. Where multiple spaced-apart magnet(s) and/or metal piece(s) are used, the magnet(s) and/or metal piece(s) are either regularly spaced-apart or asymmetrically spaced. The coupling device is generally designed to hold tubular objects together. The coupling device has numerous advantages, including, for example, rapid assembly and disassembly, pressure release characteristics, superior ergonomics for the user, increased adjustability for specific applications, and improved durability.

Abstract: A method of coupling the upper and lower section of a humidifier container used to humidify oxygen gas, using magnetic coupling means. A series of corresponding magnets around the container, located externally to the device or internally, secure the lower part or vessel to the upper part or cap. Using magnets opposing an attracted metal may he used in lieu of corresponding magnet to magnet attraction which requires the poles of the magnets be oriented with their poles to attract each other.

Abstract: A draw guide for a hunting bow is disclosed. Guide members are interposed between the bow and the string in order to support the arrow during the shooting process and to permit the string to pass therethrough during the aforementioned process. In this manner, the arrow is supported by the guide members during the shooting process while the string is permitted to pass therethrough thus allowing shorter arrows to be utilized.
