Patent number: 9570753Abstract: An improved electrolyte battery is provided that includes a tank assembly adapted to hold an amount of an anolyte and a catholyte, a number of cell stacks operably connected to the tank assembly, each stack formed of a number of flow frames disposed between end caps and a number of power converters operatively connected to the cell stacks. The cell stacks are formed with a number of flow frames each including individual inlets and outlets for anolyte and catholyte fluids and a separator disposed between flow frames defining anodic and cathodic half cells between each pair of flow frames. The power converter is configured to connect the battery with either forward or reverse polarity to a DC power source, such as a DC bus. The anodic and cathodic half cells switch as a function of the polarity by which the battery is connected to the Dc power source.Type: GrantFiled: August 22, 2012Date of Patent: February 14, 2017Assignee: EnSync, Inc.Inventors: Kevin Dennis, Nathan Coad, Peter Lex, Jeffrey A.

Publication number: 20140339743Abstract: Plastic preforms are introduced into a blow mould and are expanded by applying a flowable medium thereto, which is introduced into the internal space of the plastic preforms, wherein the blow mould includes at least two lateral parts which form a cavity during the expansion of the plastic preforms, within which the plastic containers are expanded. The lateral parts are respectively provided on lateral part carriers that are moved relative to each other for opening and closing the blow mould. At least one arrangement of a lateral part carrier and the lateral part provided thereon has an expansion element that can have a gaseous medium applied thereto. The expansion element ensures, when the gaseous medium is applied thereto, that one lateral part is moved towards the other lateral part. During the expansion of the plastic preforms, at least two different pressure levels are applied.Type: ApplicationFiled: May 9, 2014Publication date: November 20, 2014Applicant: KRONES AGInventors: Dieter Finger, Peter Lex, Thomas Spitzer

Publication number: 20140227629Abstract: Disclosed is method for enhancing electrolyte flowing mechanism within electrodes in flow battery cells by employing half-cell spacer screens that may be welded to at least one surface of each electrode sheet. Half-cell spacer screens may provide a constant gap thickness between electrode sheet and micro-porous separator membrane. Half-cell spacer screens may be made of a bromine inert thermoplastic such as polypropylene or polyethylene and may include at least one thin layer of strands. Additionally, the disclosed half-cell spacer screens may exhibit diamond pattern netting or any other suitable pattern. The inclusion of half-cell spacer screens may allow an improved distribution of electrolyte throughout the surface of electrode sheet, thereby improving performance flow batteries.Type: ApplicationFiled: February 18, 2014Publication date: August 14, 2014Applicant: ZBB Energy CorporationInventors: Nathan Coad, Peter Lex

Publication number: 20140162104Abstract: An improved chemical composition and manufacturing process for a battery electrode are disclosed. This battery electrode may be later arranged in flowing electrolyte battery cells. Battery electrode material formulation may include a mixture of polypropylene, carbon black, graphite, bonding additives and other substances in different concentrations. The inclusion of graphite may reduce the amount of carbon black in the mixture, thereby reducing the swelling of the battery electrode in the presence of bromine. Moreover, material formulation may reduce warpage caused by the swelling of electrode material, and may additionally improve the performance and properties of flowing electrolyte batteries. An extrusion molding process may be employed in order to fabricate the disclosed battery electrode.Type: ApplicationFiled: February 18, 2014Publication date: June 12, 2014Applicants: Lotte Chemical Corporation, ZBB Energy CorporationInventors: Peter Lex, Nathan Coad

Publication number: 20140162096Abstract: Disclosed herein are formulation components for the manufacturing of a flow frame structure that can be integrated in flowing electrolyte batteries. These formulation components for manufacturing flow frames may include, but are not limited to, polypropylene, glass fiber, a coupling agent and an elastomer. A mixing and extrusion process may be employed to formulate the material and produce pre-formulated pellets for the manufacturing of flow frames. As flow frames may be integrated with electrodes (or membranes), the disclosed flow frame formulation may achieve a desired Melt Flow Index (MFI) range and may allow an improved bonding between electrodes (or membranes) and flow frame, therefore, simplifying manufacturing process and achieving higher performance and longer lifetime of flowing electrolyte batteries.Type: ApplicationFiled: February 18, 2014Publication date: June 12, 2014Applicants: Lotte Chemical Corporation, ZBB Energy CorporationInventors: Peter Lex, Nathan Coad

Patent number: 7103143Abstract: An X-ray examination apparatus includes an X-ray source, an X-ray detector and an exposure control system. The exposure control system is arranged to control the X-ray source so as to perform a test exposure at a low X-ray dose and to perform an X-ray exposure at a higher X-ray dose. The X-ray detector applies a control signal resulting from the test exposure to the exposure control system and the X-ray source is adjusted on the basis of this control signal. The X-ray exposure produces an X-ray image and the X-ray detector supplies an image signal representing this X-ray image. The exposure control system is arranged to adjust the X-ray detector to a low spatial resolution during the test exposure and to a high spatial resolution during the X-ray exposure. The X-ray detector preferably includes a sensor matrix having sensor elements arranged in columns and rows. The spatial resolution is adjusted by deriving the control signal and the image signal from large and small groups of sensor elements, respectively.Type: GrantFiled: May 12, 2005Date of Patent: September 5, 2006Assignee: Koninklijke Philips Electronics, N.V.Inventors: Peter Lex Alving, Albert Louw Faber
