Abstract:
The present invention is a method and an eddy current system for non-contact determination of the resistance between the current lead stripe and the coating during continuous fabrication of chemical power sources such as batteries, supercapacitors, photovoltaic modules and the like. Both the method and the non-destructive test system for practicing the method are described. The method includes placing of an integrated measuring transducer containing two strap-type eddy current probes above the surface of the coating applied to the metallic current lead stripe in the region of the shaft guiding the stripe movement, so that all the points of the operating surface of the transducer being at an equal distance from the stripe surface coating so that the two probes would take measurements on the same area of the coating.

Abstract:
A method of forming nanoporous carbon material includes the steps of providing a natural carbonaceous material, the carbonaceous material having pores being filled with at least one other material, and treating the carbonaceous material with a strong acid or a strong base, wherein the other material is removed from the pores to form a nanoporous carbon material having open pores available for organic electrolyte. The nanoporous carbon material can be used to form composite electrodes by impregnating the open pores with an organic electrolyte. Such electrodes can be used to form electrochemical double layer capacitors (EDLC), such as by disposing an electrically insulating layer comprising a plurality of nano-size dielectric particles together with a binder directly onto a surface of at least one of anode and the cathode, and interposing the electrically insulating layer between the anode and the cathode. EDLCs formed using the invention are low cost and provide large specific energy stored and low inner resistance resulting in high power output.

An apparatus and method for dissolving gas or gases in liquid fuel to improve combustion of the liquid fuel when injected into a combustion chamber is provided. A gas-charger unit is provided to dissolve the gas into liquid fuel at a first pressure. The pressure of the fuel/gas solution is raised to a second pressure before injection of the atomized fuel into a combustion chamber. In one embodiment, a high pressure gas or gasses is/are introduced into the gas charger at a crosscurrent to the liquid fuel. In another embodiment, a gas charger for dissolving gas into a liquid fuel is provided including a plurality of highly porous baffles to increase the contact surfaces between the gas and the liquid.

Abstract:
The invention concerns an apparatus for controlling the rotational speed of the spindles of a spinning preparatory machine equipped with spindles and flyers.The proposed control arrangement comprises an infinitely variable variator, which is adapted or adjusted by using a control shaft which is rotatably indexed or stepped. The control or adjustment shaft is moved by a control motor which received its control or switching impulses from a motor control device comprising a programmable indicator or set value transmitter for the desired or set value and a correction element.According to a particularly advantageous design the correction element is of the form of a crossbar distributor arrangement.The apparatus is comfortable and easy to use by the operating personnel and permits, among other advantages, extremely accurate adaptation or adjustment of the spindle rotational speed. The adaption operations can be effected while the machine is running.
Abstract:
A method of the present invention is used for the high-rate deposition of materials, such as carbon, silicon, metals, metal oxides, and the like, onto a metal substrate defined by a metal current collector. The particles of the material are mixed with fluid and are injected against the metal tape at high pressure and high velocity. The particles of the material form an active layer of the metal current collector. The metal current collector is used as a cathode or anode combined with a separator to form a cell of a secondary battery, metal-ceramic membranes, film composite metal-ceramic materials for electronic devices.
