  • Patent number: 11040189
    Abstract: An electrode assembly may include an electrode support made of a first electrically insulative material and an electrode on the electrode support, the electrode having a working surface extending generally transverse to a thickness of the electrode. The electrode assembly may further include an insulative spacer retained in the electrode and made of a second electrically insulative material. The second electrically insulative material may be different from the first electrically insulative material. The insulative spacer of the electrode assembly may have a body portion extending into the thickness of the electrode, and a head portion protruding beyond the working surface of the electrode.

  • Patent number: 7592060
    Abstract: A method of preparing a cellulosic article includes a step of combining cellulosic material and binder resin to form treated cellulosic material. A mat is formed of a plurality of layers of the treated cellulosic material. The method also includes the steps of interfering with bonding of resin between two adjacent layers of the mat, and applying heat and pressure to the mat to form a cellulosic composite article having an internal blistered pattern. A consolidated cellulosic article includes a consolidated cellulosic mat and a layer of blisters disposed in the consolidated cellulosic mat.

  • Patent number: 7314585
    Abstract: A method of manufacturing a contoured, consolidated cellulosic article, with variable basis weight, is disclosed. The method employs a former to create a mat having a substantially uniform thickness which is pre-pressed to retain its shape. The pre-pressed mat is then machined along at least one surface to result in a desirable contour. The contoured mat is then consolidated within a secondary press. The secondary press preferably includes platens shaped complementarily to the surfaces of the mat.

  • Patent number: 7264462
    Abstract: A consolidated cellulosic article of increased thickness and target face density, as well as an apparatus and method of manufacturing same, are disclosed. The apparatus includes first and second dies adapted to move toward one another with a mat of cellulosic material and a binding agent therebetween. When the dies move together, the mat is compressed under pressure and heat with forms on one of the dies forming indentations in the mat. Compression zones of increased density form between the indentations and a first face of the mat. By spacing the forms appropriately, the compression zones overlap, and the first face of the resulting consolidated board is provided with substantially uniform density. Since the entire board is not compressed to the same degree, its overall thickness is enhanced while the density of the first face of the mat is increased, and relatively little material is used.

  • Patent number: 7096916
    Abstract: A method and system for manufacturing a consolidated cellulosic article having first and second surfaces of a desired contour, a uniform density and variable caliper and basis weight are disclosed. The method and system employ a primary press having first and second similarly contoured platens to consolidate a mat of cellulosic material and a binding agent to a softboard having first level of density with first and second opposed sides of similar contour. A removal tool is then employed to remove cellulosic material from one or both of the first and second sides in a planar fashion. The resulting mat is then compressed a second time by a secondary press having first and second platens corresponding in shape to a higher density level while maintaining a substantially uniform caliper and basis weight.
