Richard S. Lenzing 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).

  • Patent number: 6433505
    Abstract: A phase shifting network for an inductor motor is provided. The network includes a resistor connected in series with each motor phase coil of a pair of motor phases. The network further includes a capacitor connected between the motor phases. The inventive phase shifting network produces current and voltage waveforms within the motor phase coils that are smoother, more equal, and less subject to harmonic distortion as compared to the waveforms generated by conventional phase shifting networks.
    Type: Grant

  • Patent number: 5032816
    Abstract: An improved conductor for an inductor device of the type having varying current carrying requirements along the length of the conductor, the improvement comprising having the conductor contoured such that the cross sectional area of the conductor varies substantially directly as the current carrying requirements of the conductor vary. In one embodiment, a coil for a variable transformer is cut from a cylinder of conductor material by numerically controlled machining, producing a contoured conductor and eliminating the requirement for coiling or winding of the conductor.

  • Patent number: 4577146
    Abstract: An adjustable voltage transformer having a commutating surface formed of segments of electrical conductors upon which a contact brush is movable while in electrical engagement therewith. Means are provided to "step" the brush between segments, so that when at rest, the brush contacts no more than one segment, thus reducing short-circuiting currents and overheating; however, when the brush is being moved, it is in contact with two segments, thus allowing uninterrupted output from the transformer.

  • Patent number: 4560970
    Abstract: A coil for a variable transformer is provided having multiple layers of wire. Winding of such a coil is facilitated by providing an end form having a series of raised fins, or partitions, between which stacked layers of wire are held. The construction provides for easy and economical machine-winding and ensures that the segments of wire forming the commutating surface are held relatively immovable with respect to each other, thus preserving the integrity of the commutating surface.

  • Patent number: 4496923
    Abstract: An improved electrical device of the type having a coil and a base and having a thermally conductive electrical insulating material placed between the coil and the base so as to facilitate the flow of heat from the coil to the base, and further having a base with an extended surface area so as to promote the flow of heat from the base to the surrounding air. In one construction, the insulating material is cast in place, thus cementing the coil and the base together.

  • Patent number: 4431978
    Abstract: An integrally molded coil assembly extends about the intermediate leg, and is wedged between the outer legs of an E-frame magnet. It has rigid interior walls and top and bottom flange portions. Flexible flange extensions extend from the sides of the flange portions. The extensions are coplanar with the flange portions during the coil winding operations, and are bent in overlapping relationship during assembly of the coil form on the magnet. The flange portions are dimensioned so that the extensions are tightly wedged against the outer legs.

  • Patent number: 4371855
    Abstract: A contactor assembly comprises an arc chute having side walls, an intermediate wall and legs extending from the latter. A stationary electromagnet assembly is supported by a metallic support member, i.e. base plate, whose sidearms are secured to the bottom of the legs. Pole shader rings are nested in the arms of the magnet assembly. Portions of the pole shaders extending transversely from the magnet legs are clamped against platforms on the sidewalls of the arc chute by the spring force exerted by the base plate. An armature is secured to a moveable contact carrier that carries a spring biased contact bridge. The wear allowance of the contact carrier can be readily controlled by machining the platforms to the correct height. This is accomplished prior to installation of the electromagnet assembly by exerting a force directly against the contact bridges to close them against the stationary contacts. The platforms are then machined to a predetermined depth from the pole face of the armature.

  • Patent number: 4345224
    Abstract: A contactor assembly has a moveable contact carrier extending through an arc chute containing stationary terminals. The arms of the contact carrier support moveable contact bridges that are spring mounted on pin members. The pin members are specially configured to facilitate initial insertion of the spring between the pin head and the contact bridge with minimal radial displacement of the spring turns. The head of the pin member has a thickness smaller than the inside diameter of the smallest turn of the helical spring. The head and neck are specially configured in the direction orthogonal thereto, to facilitate insertion of the spring at an oblique angle such that one end of the spring snaps over the flanged end of the pin before the other end.
