Patent number: 5451476Abstract: Cathode for collecting and donating charged particles. The cathode comprises current collector means for collecting charged particles injected into the cathode from an anode. Current conducting means are provided which are electrically interfaced to an ion transporting medium and to the current collector means. The current conductor means transfers charge from the current collector means to the ion transporting medium. The current conducting means comprises a plurality of core members and a charge donor material that donates charge to the ion transporting medium when the current collector means collects charged particles. A battery is also provided comprising the cathode and an anode means for discharging charged particles when the battery is loaded. Methods of manufacturing the cathode comprise coating a plurality of core members with a charge donating material and interfacing the coated core members to an ion transporting medium to provide a subassembly composite.Type: GrantFiled: November 23, 1992Date of Patent: September 19, 1995Assignee: The Trustees of the University of PennsylvaniaInventor: Jack Y.

Patent number: 5315306Abstract: Systems and methods that use a CW Doppler radar to monitor paint particle velocities as they are sprayed from a paint gun to optimize the application of sprayed paint onto the object, and provide a closed loop spray painting system and paint spraying method that controls the application of paint in real time using data generated by the radar. The Doppler radar and a signal analyzer are used to analyze the Doppler return signals and display data indicative of the velocity of the paint particles. The data may be used by an operator to manually adjust the paint spray system. In addition, the spectrum analyzer may be used to generate and couple control signals to the paint spray system to provide for closed loop feedback control of thereof. One method comprises the following steps. Spraying paint particles toward an object that is to be painted using a paint spray gun. Radiating Doppler radar signals at the paint particles that are moving toward the object.Type: GrantFiled: July 30, 1993Date of Patent: May 24, 1994Assignee: Hughes Aircraft CompanyInventors: John K. Doughty, Gerald Brand, Jack Y. Josefowicz

Patent number: 5272133Abstract: An oxide superconductor having a high critical temperature is provided with a passivation coating comprising a first layer of a Group II oxide, such as magnesium oxide, and a second layer of a polymer, such as polyimide. The Group II oxide is formed under conditions to be substantially amorphous. After depositing the Group II, layer, the encapsulated superconductor is heated to an elevated temperature for a period of time in an oxidizing atmosphere. This restores the high critical temperature to its original value. The polymer is then coated on top of the Group II oxide and cured. The passivation coating is resistant to strong acids, strong bases, and water, is robust, hard, and resilient against scratching.Type: GrantFiled: February 27, 1992Date of Patent: December 21, 1993Assignee: Hughes Aircraft CompanyInventors: Jack Y. Josefowicz, David B. Rensch, Kai-Wei Nieh

Patent number: 4597839Abstract: An anode of reducing agent material particulates is introduced into an electrolytic solvent bath under compression. The carbon material is selected such that there is a minimum number of particle contacts. In such a selection, the contact surface area is important and is determined primarily by particle size. The compression of the anode is maintained greater than about 5 psi.Type: GrantFiled: December 14, 1983Date of Patent: July 1, 1986Assignee: Atlantic Richfield CompanyInventor: Jack Y. Josefowicz

Patent number: 4595466Abstract: A cell for the electrolytic deposition of metal at low temperatures and low electrical consumption in which an anode of a metal oxide and reducing agent immersed in an electrolytic molten halide salt bath comprises lithium chloride and sodium fluoride, the bath formulated to have high electrical conductivity and very low solubility for the metal oxide, as well as the recovered metal. The electrolytic molten halide salt bath is substantially absent of the metal to be recovered.Type: GrantFiled: March 7, 1985Date of Patent: June 17, 1986Assignee: Atlantic Richfield CompanyInventor: Jack Y. Josefowicz

Patent number: 4582584Abstract: A cell for the electrolytic deposition of metal at low temperatures and low electrical consumption in which the electrolytic molten bath comprises halide salt having low solubility for the metal oxide at normal operating conditions. The novel anode of this invention comprises an effective amount of a selected N-type or P-type metal.Type: GrantFiled: March 7, 1985Date of Patent: April 15, 1986Assignee: Atlantic Richfield CompanyInventor: Jack Y.

Patent number: 4547443Abstract: The unitary electrode (10) comprises a porous sheet (12) of fiberglass the strands (14) of which contain a coating (16) of conductive tin oxide. The lower portion of the sheet contains a layer (18) of resin and the upper layer (20) contains lead dioxide forming a positive active electrode on an electrolyte-impervious layer. The strands (14) form a continuous conduction path through both layers (16, 18). Tin oxide is prevented from reduction by coating the surface of the plate facing the negative electrode with a conductive, impervious layer resistant to reduction such as a thin film (130) of lead or graphite filled resin adhered to the plate with a layer (31) of conductive adhesive. The plate (10) can be formed by casting a molten resin from kettle (60) onto a sheet of glass wool (56) overlying a sheet of lead foil and then applying positive active paste from hopper (64) into the upper layer (68).Type: GrantFiled: November 14, 1983Date of Patent: October 15, 1985Assignees: Atlantic-Richfield Company, California Institute of TechnologyInventors: John J. Rowlette, Thomas J. Clough, Jack Y. Josefowicz, John W. Sibert

Patent number: 4547272Abstract: An anode of a mixture of reducing agent and metal oxide particulates is inserted into an electrolytic solvent bath under compression. In forming the particulate anode, the materials of construction are selected such that there is a minimum number of particle contacts. In such a selection, the contact surface area is important and is determined primarily by particle size. The compression of the anode is maintained to deform the particles during electrolysis.Type: GrantFiled: December 14, 1983Date of Patent: October 15, 1985Assignee: Atlantic Richfield CompanyInventor: Jack Y.
