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.

TAPERED PLASTERBOARDS AND METHODS FOR MAKING THEM

Disclosed herein are plaster boards having a first surface and an opposing second surface, and a first edge and an opposing second edge that bound the first surface and the second surface.

The first surface includes a first section and a second section, the first section being raised compared to the second section, the second section abutting the second edge. The second surface includes a first section and a second section that are separated by a boundary between the first edge and the second edge. The first section of the second surface is substantially parallel to the first section of the first surface. The second section of the second surface slopes toward the first surface from the boundary toward the second edge. Methods for making the plaster boards involve forming wet plaster material and drying the wet plaster material such that the wet plaster material hardens into a plasterboard.

APPARATUS AND METHOD OF MANUFACTURING CERAMIC HONEYCOMB BODY
20190099916 · 2019-04-04 ·

An apparatus and method of manufacturing a porous ceramic segmented honeycomb body (340,340) comprising axial channels (216) extending from a first end face (220) to a second end face (224). A plurality of porous ceramic honeycomb segments (204) is moved axially past respective apertures (110) of an adhesive applying device (100). Adhesive (118) is applied through openings (126) in the adhesive applying device (100) onto peripheral axial surfaces of each porous ceramic honeycomb segment (204). The plurality of porous ceramic honeycomb segments (204) enters a wide opening (318) of a tapered chamber (314) and exits a narrow opening (322) of the tapered chamber (314); a tapered wall (326) from the wide opening (318) to the narrow opening (322) presses the plurality of porous ceramic honeycomb segments (204) together forming the porous ceramic segmented honeycomb body (340,340). The adhesive (118) on the peripheral axial surfaces between respective porous ceramic honeycomb segments (204) is distributed by the pressing.

Method for Manufacturing Toilet Blank, and Toilet Blank

The present invention relates to a method for manufacturing a toilet blank. The manufacturing method includes the following steps: a grouting step: producing a seat blank, an inner container blank and a main body blank; a first demolding step: demolding a part of a main body mold, a part of an inner container mold and a part of a seat mold; a first bonding step: bonding a first bonding surface of the inner container blank and a bonding surface of the main body blank to each other; a second demolding step: demolding another part of the inner container mold from the inner container blank; a second bonding step: bonding a bonding surface of the seat blank and a second bonding surface of the inner container blank to each other, and a third demolding step: demolding demolded parts of the seat mold, the inner container mold and the main body mold from a bonded toilet blank. By bonding the blanks to each other with parts of the molds not demolded, the contact of an operator with the blanks is reduced during bonding, and the blanks can be accurately located relative to each other using the parts of the molds.
