Patents by Inventor Herman Schellstede

Herman Schellstede 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).

  • Publication number: 20220355224
    Abstract: A drilling mud remediation and drilling cutting treatment device and method. There are three main components: a vacuum liquid solid separator; a pelletizer; and an induction furnace. The liquid solid separator has a seamless filter belt configured to carry a mixture of liquids and solids over a vacuum. A slurry comprised of drilling mud and cuttings is deposited on the filter belt. An applicator ensures that the slurry is deposited evenly across the entire filter belt at a uniform thickness. The vacuum removes most of the liquids for further treatment and reuse. The solids are transferred to a pelletizer which compacts them into relatively uniform pellets while removing much residual liquid. The pelletized cuttings are then passed through an induction furnace, which removes any residual liquids, renderings the cuttings safe for disposal.

  • Publication number: 20070243063
    Abstract: Structures and methods for elevating and retracting offshore wind turbine assemblies. Structures and methods are presented for elevating and retracting offshore wind turbine assemblies mounted on a tower in order to facilitate both service of the assemblies at any time, as well as preservation of the assemblies through storms or other high-wind weather events. Among the structures presented are folding wind turbine blades that may be folded into compact clusters and secured to braces in order to minimize damage during storms or other high-wind events.

  • Publication number: 20070243774
    Abstract: An auxiliary vehicle powered vessel. The vessel is configured to carry an auxiliary vehicle, such as an all terrain vehicle, preferably on its deck. The all terrain vehicle can be driven onto and off of the vessel. When in the vessel, the auxiliary vehicle engages a transmission that transfers power to the vessel's propulsion system. When the vessel reaches its destination, the auxiliary vehicle can be driven off the vessel. Later, the auxiliary vehicle can be returned to the vessel and used to power the vessel again. The preferred embodiment of the vessel is provided with a “mud boat” propulsion system to allow operation in shallow waters. The preferred embodiment of the vessel is also designed to overcome the stability challenges posed by the high center of gravity that will arise from carrying objects such the auxiliary vehicle in the vessel, particularly if such objects are transported on deck.

  • Publication number: 20060096119
    Abstract: A liquid solid separator utilizing inductive heating. An electrically conductive scroll conveyor is contained within a non-magnetic and non-conductive housing under vacuum. A moveable alternating electric coil is disposed around the housing. The scroll pulls the solids through the housing. Operation of the coil heats the scroll which heats the solids. The vacuum lowers the boiling point of the liquids, and they are vaporized at a relatively low temperature. The vapors are condensed and collected. Because of the low temperatures, the separated liquids are less likely to deteriorate during separation, facilitating recycling. Thermocouples and a computer track the internal temperature of the separator and coordinate the position of the coil to maintain the desired temperature. The housing is provided with a heat insulating outer layer and the interior of the scroll is pressurized with nitrogen. The separator surfaces exposed to the atmosphere are maintained at or below 150° F.
