Jon A. Jensen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A valve assembly for use in the coupling of two members. The first member has an exterior surface and an interior surface. The interior surface defines a coupling sleeve and a valve sleeve. A fluid passageway is in communication between the coupling sleeve and the valve sleeve. A valve is positioned in the valve sleeve. The valve is biased toward the fluid passageway by a coiled spring. A valve pusher having a first end and a second end is positioned in the coupling sleeve and the fluid passageway. The assembly has a second member having an outer surface, an inner surface and a terminal portion. When the second member is inserted in the coupling sleeve, the terminal portion engages the first end of the valve pusher causing the second end of the pusher to engage the valve to unseat the valve to allow unrestricted fluid flow between the first member and the second member.
Abstract: A refrigeration system service coupling having a valved service adapter employing a spring biased sleeve valve to maintain the adapter valve in a closed no flow condition except when the service adapter is properly connected to a charging port of predetermined configuration and capable of retaining the service adapter sleeve valve to permit opening of the service adapter valve upon the service adapter being properly connected to the charging port.

Abstract: A control mechanism for adjusting the speed of a treadmill belt is disclosed. The mechanism includes a disk mounted on a drum of the treadmill. A drive head which defines a plurality of dimensionally distinct cross-sectional circumferences is biased against the disk. The drive head is mounted on the drive shaft of a motor, the motor is mounted for displacement vis-a-vis the disk responsive to the displacement of a cable-fitted control lever which is connected thereto. A displacement of the motor adjusts the drive head positioning whereby the length of a path of the disk over the drive head's exterior surface may be modified, thereby causing a change in the angular velocity of the disk.
