    • A wound resistor-capacitor network having stable frequency response over a wide frequency range (e.g., 60 cycles to 100 kilohertz), is produced by forming a pair of aligned circumferentially extending resistance paths in one of two strips of metallized dielectric film. Forming of the resistance paths is accomplished as the two metallized strips are being wound to form an R-C network roll, by removing metal from the one strip along a first line to produce a gap in the metal layer in parallel spaced relationship to an adjacent edge of the film. Subsequently, removal of metal from the first strip also is initiated along a second line spaced inward from the first line, to produce another gap in the metal layer, thereby forming an elongated first path of desired resistance between the two lines. Metal removal along the first line then is temporarily interrupted to provide a lead termination area and a current steering path at the adjacent end of the network roll, on either side of the strip midpoint. Metal removal along a third line in alignment with the first line then is continued until an elongated second path of desired resistance has been formed between the second and third lines, at which time metal removal along the second line is terminated. Lines of metal also may be removed from the second dielectric film to provide a lead termination area and a current steering path at the opposite end of the wound network roll. Preferably, the metal is removed with the split beam of a single laser and the lines of removal are symmetrical on opposite sides of each strip's longitudinal midpoint.
    • 通过在两个金属化介电膜之一中形成一对对齐的周向延伸的电阻路径,产生在宽频率范围(例如,60个周期至100千赫兹)上具有稳定频率响应的卷绕电阻器 - 电容器网络。 电阻路径的形成是通过两个金属化带被卷绕形成RC网络辊,通过沿着第一条线从一个条移除金属以在金属层中产生与之相邻边缘平行间隔开的​​间隙 这个电影。 随后,从第一条带去除金属也沿着与第一线向内间隔开的第二线开始,以在金属层中产生另一个间隙,从而在两条线之间形成期望电阻的细长的第一路径。 沿着第一行的金属去除然后被暂时中断,以在带状中点的任一侧上的网络辊的相邻端处提供引线终端区域和当前的转向路径。 沿着与第一线对准的第三线的金属去除继续进行,直到在第二和第三线之间形成了所需电阻的细长的第二路径,此时沿着第二条线的金属去除被终止。 也可以从第二电介质膜移除金属线以在卷绕网络辊的相对端提供引线终止区域和电流转向路径。 优选地,用单个激光器的分裂光束去除金属,并且去除线在每个条带的纵向中点的相对侧上对称。

    • A fireplace includes a first enclosure defining a combustion chamber and having a front that allows viewing within the combustion chamber, one or more back panels opposite the front, a plurality of side panels, a top panel, and a bottom panel. At least one of the one or more back panels and plurality of side panels includes a plurality of optically transmissive regions. A second enclosure includes a plurality of panels that are secured together to surround the plurality of side panels. A flame-generating element is disposed within the combustion chamber adjacent the bottom panel and is adapted to generate a flame. A lighting assembly between the first enclosure and the second enclosure is operable to project light onto portions of the second enclosure facing the first enclosure to passively illuminate an interior of the combustion chamber through the plurality of optically transmissive regions.
