Abstract: A bottle neck insert can include a cylindrical body having a first end and a second end, the cylindrical body having a plurality of rings; a flange provided at the first end, the flange protruding outwardly from the cylindrical body in a radial direction of the cylindrical body; and a valve section at the second end, the valve section having at least one slit, wherein the flange is configured to seat the insert onto a neck of a bottle and the valve section is configured to allow a pipette to pass through. A bottle storage system, can include a bottle having a neck with a smooth interior surface; an insert that is configured to fit inside the neck of the bottle; and a pipette assembly that is configured to proceed through the insert into the bottle.

Abstract: The flexible earphone cover has a flexible main body and a flexible ear cone that extends from the main body. The flexible main body is configured to substantially encase a portion of an earphone. The flexible main body defines an internal cavity for receiving the earphone. It also defines a first opening at a side of the cavity for receiving the earphone there-through. The flexible main body defines a second opening at a side of the cavity. The second opening is smaller than the first opening. Finally, the flexible main body defines a third opening at a side of the cavity. The third opening is smaller than the first opening and the second opening. The flexible ear cone defines a converging passageway from the second opening to an exit configured to direct sound into an ear canal of an ear of a user.

Abstract: Devices, systems and methods of converting the necks on lamp shades into threadable couplers that allow the shades with the couplers to be screwed onto the exterior threads on light sockets, such as those types of sockets found on wall mounted and ceiling mounted candelabras and ceiling fans. The couplers can include plate members that are fastened in a sandwich configuration on both the inside and outside of the neck portion of the shade with the sandwiched plate members having an interior threaded surfaces. Modified lamp shades can be screwed to exterior threaded light sockets on candelabra lights, pendant lights, ceiling fan lights, and any other type of lamp sockets that have removable lamp shades.

Abstract: A system for heating a pool of water is provided. An inlet is provided for liquid to be delivered to the pool of water. The system includes an attachment apparatus having a body defining a fluid passageway from a first opening to a second opening. A third opening is disposed between the first and second opening. The attachment connects to the inlet for receiving the liquid. An adjustable diverging mechanism is mounted to the attachment operable to redirect flow out of the third opening. A tube having a flow channel and thermally conductive outer surface is coupled to the third opening and extends out of the pool to be exposed to environmental conditions and absorb thermal energy. The liquid passing through the flow channel of the tube returns to the pool of liquid and heated when passing through the tube prior to returning to the pool.

Abstract: An electrical plug adapter has a plug body, female receptacles in one surface of the plug body, male prongs extending from another surface of the plug body, and a male catch mechanism associated with one of the male prongs and resiliently biased to a catch position relative to the one male prong. The male catch mechanism is configured to catch on an object in a standard electrical outlet when the male prongs are inserted into corresponding receptacles of the outlet. An actuator on the plug body is configured, when actuated, to selectively move the male catch mechanism to a release position relative to the one male prong and allow the male prongs to be removed from the corresponding receptacles. A one-way retention mechanism can be associated with one of the female receptacles and configured to permanently retain a male connector prong from a standard electrical connector plug when inserted into the female receptacles.
