The TRE assemble permanent column formwork comprises first panels, second panels, circumferential bolts, longitudinal bolts, nuts and gaskets; the formwork is manufactured from an engineered cementitious composite ECC and a woven fabric net; the first panels are used for assembling the column formwork at the two ends of a column, and the second panels are used for assembling the column formwork in the middle section of the column; the panels are provided with preformed bolt holes, and the bolt holes among the panels are corresponding to each other for bolt connections; the bolts include circumferential bolts and longitudinal bolts. The TRE permanent column formwork provided by the present invention can reduce material waste, labor cost, and project cost. Besides, the panels have advantages of easy and firm assembling, convenient transportation and low manufacturing cost, and the formwork has great application prospects.

A method of manufacturing ceramic tape includes a step of directing a tape of partially-sintered ceramic into a furnace. The tape is partially-sintered such that grains of the ceramic are fused to one another yet the tape still includes at least 10% porosity by volume, where the porosity refers to volume of the tape unoccupied by the ceramic. The method further includes steps of conveying the tape through the furnace and further sintering the tape as the tape is conveyed through the furnace. The porosity of the tape decreases during the further sintering step.

A method is provided for producing an article which is transparent to near-wave IR, mid-wave and Long-wave multi-spectral and IR wavelength in the region of 0.4 μm to 16 μm. The method includes the steps of (a) Producing ultra-fine powder of CaLa.sub.2S.sub.4 via SPLTS process, (b) followed by pretreatment of the ultra-fine powder under inert and reducing gas conditions including H.sub.2 or Argon or N.sub.2 or H.sub.2/H.sub.2S, H.sub.2S, and mixtures there of (c) followed by sieving the powder in 140 mesh screen and cold pressing the powder at 7000 psi for 7 min. into a disk shaped green body (d) then Cold-Isostatic Pressing (CIP) at 40,000 psi for 5 min in a rubber mold (e) finally sintered article of CaLa.sub.2S.sub.4 disk of 25.4 mm diameter with ultra-high density containing cubic phase of CaLa.sub.2S.sub.4 to yield IR transmission of a peak value of 57% within the IR wavelength range of 2 μm to 16 μm, either by using microwave sintering followed by hot isostatic press or spark plasma sintering followed by hot isostatic press or vacuum sintering at (3×10.sup.−6 torr) followed by hot isostatic press or hot press sintering followed by hot isostatic press and finally followed by mirror polished IR article, is obtained.

Gypsum panels and methods of making the same are provided. A method of making a gypsum panel includes forming a first gypsum slurry by combining stucco, water, a siliconate, and a phosphate salt or polymer, and setting the first gypsum slurry to form at least part of a core of the gypsum panel, wherein the gypsum panel displays a 2-hour water absorption test weight increase of at least 10 weight percent less than an otherwise identical comparative panel containing no phosphate salt or polymer in its core.

A manufacturing system includes a tape advancing through the manufacturing system and a station of the manufacturing system. The tape includes a first portion having grains of an inorganic material bound by an organic binder. The station of the manufacturing system receives the first portion of the tape and prepares the tape for sintering by chemically changing the organic binder and/or removing the organic binder from the first portion of the tape, leaving the grains of the inorganic material, to form a second portion of the tape and, at least in part, prepare the tape for sintering.

A method of producing a plurality of parts includes placing a sol mixture into a cavity of a tool, optionally placing a metal foil over a top of the cavity and placing a graphite gasket over the metal foil, and securing the tool with the sol mixture to form a tooling capsule. Tooling capsules are placed within a conveyor system and are heated until the solvent of the sol mixture reaches at least supercritical conditions of the solvent. Pressure is released within each of the tooling capsules after the supercritical conditions are reached, and then the tooling capsules are cooled to approximately room temperature. The parts are removed from the tooling capsules, and the method is continuous.

The invention relates to a device for storing objects under defined temperature conditions and humidity conditions. In particular, the invention relates to a device for curing objects made of concrete. The device has a shelving system having a plurality of shelf supports and a plurality of bearing elements for supporting shelves supported on the shelf supports and arranged one above the other in a plurality of levels, on which shelves the objects are stored. According to the invention, a flow pipe system for distributing supply air provided in a climate system is at least partially integrated into the shelving system. A plurality of shelf supports in this case are at least in sections at the same time downward pipelines of the flow pipe system that the provided supply air is able to flow through. As a result, condensation at the foot of the shelving system and thus corrosion is counteracted at the shelf supports, thus increasing the service life of the shelving system.

A method for machining by laser ablation or by micro-milling a raised and/or hollow structure on an impression of an injection mould. A method for manufacturing a ceramic or cermet item by injection using the injection mould to produce an item, and in particular a watch bezel, decorated directly during the injection.

The present invention relates to a manufacturing process for a watch component (50) in composite material with a ceramic matrix comprising the following steps: depositing in a mould a succession of layers (10, 20, 30, 40) each comprising a ceramic powder (12), at least one layer (10; 10, 30; 10, 20, 30, 40) further including fibres (14) mixed with the ceramic powder (12), the fibres (14) being arranged randomly; performing a FAST/SPS sintering operation; demoulding the sintered watch component comprising the succession of layers (10, 20, 30, 40), and optionally machining the sintered component to the final dimensions of the watch component (50). The fibres (14) are visible on the surface of the watch component (50).
