Patent number: 6195193Abstract: An improved seal member is provided as a part of an electrochromic device to bond two glass elements together in a spaced-apart relationship. In one embodiment the seal member provides improved adhesion to a reflector/electrode on the third surface of an electrochromic mirror, or to a layer of metal on the second or third surface for an electrochromic light filter. This seal member comprises a mixture of an organic resin scaling system and an adhesion promoter, where the adhesion promotor comprises a first and a second region, where the first region interacts with the reflector/electrode or the metal layer, and a second region that interacts with the organic resin sealing system, and may even chemically react with the organic resin sealing system. In another embodiment the seal member is provided with a coefficient of thermal expansion that is closer to glass than a standard epoxy sealing system.Type: GrantFiled: March 31, 2000Date of Patent: February 27, 2001Assignee: Gentex CorporationInventors: John S.

Patent number: 6168878Abstract: An electrochemical cell, and an associated process, wherein the cell includes a controlled electrode surface comprising an electrode with a metallic current collector having a surface, an electrolyte and a reduced additive. The invention further includes a passivating layer at the interface between the metallic current collector and the electrolyte. The passivating layer includes the reduced additive. This passivating layer substantially precludes contact between electrolyte solvent and surface of the metallic current collector to, in turn, substantially prevent gas formation within the cell, which would otherwise result from decomposition of the solvent upon contact with the surface of the metallic current collector. Also, the reduced additive will likewise be substantially precluded from generating a gas upon its decomposition.Type: GrantFiled: December 10, 1998Date of Patent: January 2, 2001Assignee: Mitsubishi Chemical CorporationInventors: Denis G.

Patent number: 6109539Abstract: The present invention is directed to a device for releasing a volatile substance. The device includes a housing having an interior region, a volatile substance contained within the interior region, and the ability to controllably release the volatile substance from the housing.

Patent number: 6087629Abstract: The invention comprises a control system for Arc Welding for steady and pulsed direct current welding with a single three-phase bridge converter (1) For steady direct current welding, output DC voltage (V.sub.d) and current (1.sub.d) are varied through the tapping of transformer (2). Finer voltages can be obtained through the variation of firing angles .alpha. of the thyristors of the converter (1). The contemplated control system can also be used for pulsed DC current welding with an impured dynamic response with less effort. The background current, which lies between the maximum and minimum firing angle .alpha. of the thyristors of the converter (1), is set by the transformation ratio of the transformer (2) and the pulsed current is superimposed thereon through the relatively rapid changing of the firing angle .alpha..Type: GrantFiled: July 24, 1998Date of Patent: July 11, 2000Assignee: Manoharan ThamodharanInventors: Manoharan Thamodharan, Hans-Peter Beck
