Abstract:
A coating apparatus for double-sidedly coating a porous web with a dope, includes: (i) a slot-die coating head comprising an upper lip, a lower lip and a slot between the upper lip and the lower lip, (ii) a counter element arranged opposite the lower lip across a reference plane, (iii) a slit defined between the lower lip and the counter element for passing a porous web therebetween, the slot opening up towards the slit, and (iv) a web positioning element. The web positioning element is the upper lip of the slot-die coating head. The upper lip protrudes up to the reference plane so that there is an offset between the upper lip and the lower lip, or a spacing structure on the counter element. The spacing structure protrudes up to the reference plane so that there is an offset between the spacing structure and the counter element.
Abstract:
A roll-to-roll manufacturing machine suitable for processing and producing polymer films that contain nanostructures, including but not limited to multifunctional polymer films. The machine applies a liquid polymer on a substrate to form a liquid polymer film, at least partially embeds nanostructures into the liquid polymer film, melt casts a layer of a molten polymer on the liquid polymer film to produce a thin polymer film, organizes the nanostructures in a thickness direction of the thin polymer film comprising applying an electric field to the thin polymer film, aligns the nanostructures in the thin polymer film by simultaneously subjecting the thin polymer film to heat and a field that aligns the nanostructures, and solidifies the thin polymer film to freeze the nanostructures along nanocolumns in a thickness direction of a solidified polymer film resulting therefrom.

Abstract:
A method for spreading a resin paste onto a carrier film includes feeding resin paste into a doctor blade unit having a doctor blade, using a feed device that includes a discharge opening through which the resin paste is fed from the feed device into the doctor blade unit, moving a carrier film on a base surface through a doctor blade gap that is formed between the doctor blade and the base surface, and spreading the resin paste onto the carrier film using the doctor blade. The discharge opening is positioned to be immersed into the resin paste that is in the doctor blade unit during operation of a doctor blade apparatus configured to perform the method. A resin mat installation for producing resin mats, particularly of SMC, includes at least one doctor blade apparatus as described above.
Abstract:
A cake decorating assembly, kit, and method of use comprising a mount which includes a longitudinally extending member. The assembly further comprises a top blade subassembly, a lateral blade subassembly, a gauge subassembly, and a cutting subassembly, all of which may be removably attached to the longitudinally extending member. All of the top blade subassembly, the lateral blade subassembly, the gauge subassembly, and the cutting subassembly may be vertically adjusted relative to the longitudinally extending member, while the gauge subassembly may also be horizontally adjusted relative to the longitudinally extending member. The cake decorating assembly provides for, e.g., the efficient decoration of a cake and further assists, e.g., in the even distribution of frosting on a cake.
Abstract:
Provided are an apparatus and method for coating a separator. The method includes supplying a coating solution to a receiving chamber; applying the coating solution received in the receiving chamber to a surface of the separator through a coating bar; collecting coating solution overflowing the receiving chamber by a collection chamber surrounding the receiving chamber; and returning coating solution from the collection chamber to the receiving chamber through a return line.
Abstract:
A method of forming layers of a solid oxide fuel cell. The method begins by pumping a volume of a slip form a slip reservoir to a separator reservoir. A separator and a blade are provided upon a carrier to form the separator reservoir with a gap formed between the blade and the carrier. The carrier is operated so that the carrier is transported from the separator to the blade. A layer of slip is then deposited from the separator reservoir onto the carrier. The layer of slip is then dried on the carrier.
Abstract:
The invention relates to a device for applying preferably liquid flavorings (15), in particular menthol, to a medium (16), wherein flavoring (15) is supplyable from a (storage or processing) container (10) to an applicator unit (14) via at least one conduit (11, 13). The invention is characterized in that the applicator unit (14) has a controllable valve for the application of flavoring (15) to the medium (16).
Abstract:
The present invention provides a substrate double-surface hole-filling apparatus for carrying out a hole-filling operation on a substrate which has a first surface and a second surface, comprises a first feeding device, a first scraping device, a first drying device, a second feeding device, a second scraping device, a second drying device and a turnover device. The substrate double-surface hole-filling apparatus has a turnover device turning over the substrate which needs to be carried out with hole-filling operation. Therefore, the substrate double-surface hole-filling apparatus can automatically carry out the hole-filling operation on two surfaces of the substrate without manual turnover of the substrate, thus improving production efficiency.
Abstract:
Improved coating blades are disclosed, as well as processes for manufacturing such blades. The inventive blades have an intermediate edge deposit effective to reduce heat transfer from a wear resistant top deposit to the blade substrate. In one embodiment, the intermediate layer is comprised of NiCr, possibly with embedded oxide particles. Suitably, the intermediate layer and the top deposit are applied by an HVOF process. It is also envisaged that the intermediate layer may be deposited by plasma spraying. The intermediate layer may comprise stabilized zirconia.
