Abstract: A submersible vessel which can act as a reusable bath bomb delivery system is provided. The vessel may include a housing and an opening port. The interior of the housing and ports form a chamber, which can be segmented into multiple sub-chambers. Inlet one-way valve(s) and outlet one-way valve(s) are provided on the vessel. To use, the chamber is partially filled with a mixture including an effervescent material. When water is introduced through the inlet valve, it reacts with the effervescent material, releasing carbon dioxide and dissolving the other ingredients in the mixture, building pressure in the chamber. When the pressure builds to a certain level, the inlet valve(s) are closed, and the outlet valve(s) are opened. The outlet valves may be positioned such that when the fluid and gas is expelled, the force generated may cause the vessel to spin or be propelled in the bath.

Each mounting includes a horizontal open ended bearing slot having a side slot with a constriction at the outboard end of the slot. Each axle stub includes parallel flattened surfaces which form a reduced dimension region that enables the axle stub to pass radially through the constriction, provided that radial protrusions on the flattened surfaces are out of alignment with the constriction.

Abstract: Rotational reactionary forces associated with drive trains which propel vehicles are harnessed and employed to move vehicle sub-components. The motor of a motor driven vehicle is mounted to the frame of the vehicle. The motor includes an output shaft that extends from the motor. The motor functions to rotate the output shaft, which rotation propels the vehicle. The motor further includes a motor housing from which the output shaft extends. The motor housing is pivotally mounted to the frame of the vehicle so as to allow substantial rotation of the motor housing with respect to the frame. The motor housing pivots in response to reactionary forces associated with the rotation of the output shaft. The motor housing interacts with sub-components of the vehicle such that the pivoting of the motor housing imparts motion upon the sub-components, such as air spoilers, suspension members, or trim adjustment devices.

Abstract: An animating device is attached underneath a floating waterfowl decoy that creates rings, ripples, and waves on the water surface emanating from said decoy giving the appearance that said decoy is alive. In accordance with one embodiment of the device, a long, flexible plastic tube is attached or retrofit to the keel of an existing floating decoy. An apparatus, such as a motor driven pump, a pressurized air cylinder, or a hand- or foot-operated bellows air pump supplies air to the tube and a one-way check valve is provided in the end of tube attached to the decoy to prevent water from back-filling the long flexible plastic tube. Air forced through the long flexible plastic tube bubbles out underneath the decoy and the rising bubbles create rings, ripples, and waves on the water surface to give the appearance that the decoy is alive. In another embodiment, the tube is attached to flexible container mounted under the decoy.
