Stabilizing a concrete form

A device for stabilizing a concrete form includes an anchoring member with a channel aligned along a first axis, and elongate members with cavities aligned along a second axis, the elongate members coupled to form a frame. The device may include an anchoring post for insertion through the channel of the anchoring member to secure the device to a surface, and sliders with elongate bodies for insertion into the cavities of the elongate members, where the sliders are affixed to an engagement member structurally configured for engaging the concrete form. First retaining members may be structurally configured to engage the anchoring post when inserted through the channel of the anchoring member thereby maintaining a position of the frame along the first axis. Second retaining members may be structurally configured to engage a slider when inserted into the elongate member thereby maintaining a position of the slider along the second axis.

Method of manufacturing a composite sandwich panel for an aircraft propulsion unit
10239227 · 2019-03-26 · ·

The present disclosure provides a method of manufacturing a composite sandwich panel having a core formed of a plurality of cells extending vertically between a first skin and a second skin. The method includes creating at least one first strip and a second strip from a temporary material, each strip having at least one cavity having a succession of aligned half-cells, lining the cavity of the first strip with a fibrous ply, assembling the first strip and the second strip by interlocking the cavity of the first strip with the cavity of the second strip and trapping the fibrous ply therebetween, and trimming excess temporary material of the entirety of the strips formed during the preceding assembly step so as to form a new cavity which forms a succession of aligned half-cells.

Mat-faced board

Disclosed is an improved facer mat for use as a cover sheet for gypsum board. Also disclosed are gypsum boards containing such mat facers on one or both major surfaces of the board (face and back sides when installed), a method of manufacturing such board, and a method of making the mat. The mat can comprise glass, thermoplastic, and/or thermoset fiber. In preferred embodiments, binder is included with the fiber. The mat has outer and inner surfaces. The mat comprises a first region adjacent to the outer surface defined along a horizontal plane of the mat, the first region having a first substantial thickness, and a second region adjacent to the inner surface defined along a horizontal plane of the mat, the second region having a second substantial thickness. The first region has (a) more hydrophilicity than the second region, (b) more wettability than the second region, and/or (c) less density than the second region.
