    • A method is provided for forming an extrusion die of the type used to form a ceramic monolith having thin walls defining a multiplicity of parallel tubular passageways with at least about 100 passageways per square inch, the die having a feed face and a discharge face, the feed face having a plurality of feed holes extending partially through said die and interconnecting with a network of grid slots in the discharge portion of said die formed by a plurality of grid pins which define the slot width and the wall thickness, shape and size of said passageways. The method involves the steps of forming the width of the slots larger than the desired wall thickness of the passageways, and metal plating the slot defining surfaces of the grid pins to obtain the slot width corresponding to the desired wall thickness. Plating is accomplished by the electroless plating technique using a metal selected from the group consisting of nickel, chromium, cobalt and cobalt-nickel. The resulting die has a substantially uniform coating of wear resistant metal which is strippable for replating and continued die use.
    • 提供了一种用于形成用于形成具有限定多个平行管状通道的薄壁的类型的挤出模头的方法,所述平行管状通道具有每平方英寸至少约100个通道,所述模具具有进料面和排出面, 进料面具有多个进料孔,其部分地延伸穿过所述模头并与由多个网格销形成的所述模具的排出部分中的网格槽网络互连,所述多个网格销定义了槽宽度,所述槽宽度和所述壁宽度,形状和尺寸 通道。 该方法包括形成槽的宽度大于通道的所需壁厚的步骤,以及金属电镀栅格销的槽限定表面,以获得对应于所需壁厚的槽宽度。 通过使用选自镍,铬,钴和钴 - 镍的金属的化学镀技术来实现镀覆。 所得的模具具有基本上均匀的耐磨金属涂层,其可剥离以用于重复和继续模具使用。

    • A method for controlling the coating with alumina of ceramic monolithic catalyst supports on a production basis to achieve repeatability of coating utilizing a vacuum system to distribute a coating slurry of alumina over the interior surfaces of and purge the excess coating slurry from the support at the same time that plugged tubular passageways through the support are unplugged, comprising the steps of applying the coating slurry to the support which has at least about 100 axially aligned tubular passageways to the square inch and subjecting the support to a vacuum to draw the slurry through the passageways and remove plugging and excess slurry to form a coating of alumina on the passageway surfaces. The support is dried and calcined to fix the alumina coating on the passageway surfaces.

    • An improved speaker in which a single electro-acoustic driver is mounted in a sound emitter cabinet with a spheroidal rear acoustic emitter wall, with the driver face exposed and mounted on a driver-mounting face of the cabinet and the driver body enclosed in the spheroid cabinet. The spheroidal rear emitter wall is spaced from and surrounds the driver body to receive the back wave and to responsively emit audible, clear sound from the cabinet wall to the surrounding listening area in complement to the primary sound wave from the driver face. The speaker cabinet is rigidly supported via the driver-mounting face such that the spheroidal rear emitter wall is suspended in air out of contact with surrounding surfaces.
    • 一种改进的扬声器,其中单个电声驱动器安装在具有球形后声发射器壁的声音发射器柜中,驱动器面暴露并安装在机壳的驱动器安装面上,并且驱动器主体包围在球体中 内阁。 球形后发射器壁与驱动器主体间隔开并围绕驱动器主体以接收反向波,并且响应地将来自柜壁的声音,清晰的声音发射到周围的收听区域,以补充来自驾驶员面部的主要声波。 扬声器柜通过驱动器安装面刚性地支撑,使得球形后发射器壁悬挂在与周围表面接触的空气中。
