摘要： The present invention is directed to a leak resistant battery cover for storage batteries. The battery cover provides a labyrinth of passages which provide a path from each cell vent to the atmospheric vent. The labyrinth is configured to provide a portion of each path above a level in which the electrolyte in the respective cells attains when the battery is tipped on any one of its sides or rotated ninety (90) degrees from an upright position. The labyrinth configuration prevents electrolyte from reaching the atmospheric vent and spilling out of the battery.

摘要： The present invention is directed to a leak resistant battery cover for storage batteries. The battery cover sealably engages a conventional battery housing having multiple cells separated by internal housing walls. The cover has a substantially flat interior area, a portion of which extends over part of each battery cell when the cover is placed upon a battery housing. The cover includes a cell chamber for each battery cell. Drain-back/vents communicate each cell chamber with its corresponding battery cell. The drain-back/vent, whether separate or integrated allows escape of electrolyte gases from the battery cells into the corresponding battery chamber and provide for the return of liquid electrolyte back to the cells from the cell chambers. None of the cell chambers communicate directly through the battery cover to atmosphere. One or more additional chambers are provided in the cover above the central cells of the battery housing. These additional chambers are in a geometrically central area of the battery cover away from the outside perimeter of the cover. Unlike the cell chambers, the additional chambers directly communicate with atmosphere through a convoluted passage and atmospheric vent. Additionally, each additional chamber includes a drain-back/vent directly communicating with one of the central most cells in the battery housing. Thus, the central most cells communicate with the most central cell chambers and the additional chamber. The remaining battery cells do not communicate with the additional chambers.

摘要： A fluorescent backlit display or the like embodying a generally planar light transmissive display panel, a back wall having a generally planar diffusely reflective surface facing, spaced from and parallel with the display panel an array of spaced parallel cylindrical lamps between and parallel with the display panel and back wall, improved light leveling means including masking means on the side of each lamp facing the display panel, and a light spreader associated with each lamp at the diffusely reflective back wall surface and effective to reflect laterally outwardly onto the back wall surface light flux directed thereat from the side of said lamps facing said back wall, whereupon the thus reflected light flux is directed forwardly toward areas of said display panel in front of the respective lamps. The display is of modular construction and employs a rectangular supporting frame on the front of which the display panel is mounted and in which modular lighting units are readily removably accommodated in operative position in side by side abutting relation. Each lighting unit has at least one lamp carried by a tray in a manner to dispose all of the lamps in equally spaced parallel relation when the lighting units are in operative position. Lighting unit trays are optionally sectional to facilitate handling and shipping.

摘要翻译： 本发明涉及一种用于蓄电池的防漏电池盖。 电池盖可密封地接合具有由内部壳体壁隔开的多个电池的常规电池壳体。 盖子具有基本上平坦的内部区域，当盖子放置在电池壳体上时，其一部分在每个电池单元的一部分上延伸。 盖子包括用于每个电池单元的电池室。 排水/排气口将每个电池室与其相应的电池单元进行通信。 无论是单独的还是集成的排水回排/通风口允许将电解质气体从电池单元逸出到相应的电池室中，并提供液体电解质从电池室返回到电池。 没有一个电池室通过电池盖直接与大气相通。 一个或多个附加的室设置在电池壳体的中心电池单元上方的盖中。 这些附加的室位于电池盖的远离罩的外周的几何中心区域中。 与细胞室不同，附加的腔室通过一个回旋通道和大气通气孔直接与大气连通。 此外，每个附加的室包括与电池壳体中的最中心的单元之一直接连通的排水回路/通风口。 因此，中心的细胞与最中心的细胞室和附加的室连通。 剩余的电池单元不与附加的室连通。
