Systems and methods are disclosed herein that generally involve CED devices with various features for reducing or preventing backflow. In some embodiments, CED devices include a tissue-receiving space disposed proximal to a distal fluid outlet. Tissue can be compressed into or pinched/pinned by the tissue-receiving space as the device is inserted into a target region of a patient, thereby forming a seal that reduces or prevents proximal backflow of fluid ejected from the outlet beyond the tissue-receiving space. In some embodiments, CED devices include a bullet-shaped nose proximal to a distal fluid outlet. The bullet-shaped nose forms a good seal with surrounding tissue and helps reduce or prevent backflow of infused fluid.

Some embodiments relate to a method for the direct soling of a multilayered shoe sole. The method can provide two distinct sets of mold frames for a first and a second shoe sole layer and a distinct order for the soling of the layers. In contrast to art traditional approaches, a first layer (e.g. a midsole) is first soled to an upper in a first mold frame and subsequently a second layer (e.g. an outer sole) is soled onto said first layer in a second mold frame. The method can allows for an increased design flexibility and the inclusion of additional functional or aesthetic features, such as air pockets, undercuts, toe caps or running sole tips previously not possible with direct soling processes. Some embodiments relate to an injection molding system equipped and configured for carrying out the method.

A moulding installation and method for moulding food products from a pumpable foodstuff mass are described. A revolving mould drum is provided with multiple mould cavities and a mass feed member is arranged at a fill position to transfer foodstuff mass into passing mould cavities. The foodstuff mass forms a food product in the mould cavity. A pressurized air food product ejection system includes air ducts in the mould drum that extend to the cavities and at least a portion of the surface delimiting a mould cavity is air permeable. The ejection system further includes a pressurized air source to feed pressurized air at a regulated ejection air pressure thereof to the air ducts. A controller is adapted to input at least one target parameter related to filling of the mould cavities with the foodstuff mass via the mouth of the mass feed member. The controller is adapted to automatically set an ejection air pressure by the pressurized air source on the basis of the inputted target parameter.

An imprint method includes arranging imprint material as droplets on shot region of substrate, bringing the imprint material on part of the shot region into contact with pattern region of mold and then enlarging contact region between the imprint material and the pattern region to whole region of the shot region, and curing the imprint material. in the arranging, in each of local regions located in radial direction from the part of the shot region, the imprint material is arranged such that directional drop density of the imprint material on line parallel to direction orthogonal to the radial direction and with droplets of the imprint material present thereon is smaller than that of the imprint material on line parallel to the radial direction and with droplets of the imprint material present thereon.

Devices, systems, and methods for modular molding of wind turbine blades are provided. Methods of molding wind turbine blades using a modular molding assembly or system and methods of substituting molds are provided. In some embodiments, a modular assembly includes a first base frame and a second base frame hingedly coupled to one another, a first tooling frame disposed on the first base frame, a second tooling frame disposed on the second base frame, a first shell mold coupled to the first tooling frame, and a second shell mold coupled to the second tooling frame. The first shell mold has a first mold surface and a first perimeter and the second shell mold has a second mold surface and a second perimeter. When in an open configuration, the first base frame is coplanar with the second base frame, and, in a closed configuration, the first perimeter contacts the second perimeter.

A cartridge for storing and transporting fiber-bundle-based preform charges includes a plurality of cells arranged within the housing, wherein each cell is physically adapted to receive a preform charge and prevent it from moving therein as the cartridge is transported. In some embodiments, the cartridge and preform charges it conveys are serialized.

A method of forming a three-dimensional object, is carried out by (a) providing a carrier and a build plate, the build plate comprising a semipermeable member, the semipermeable member comprising a build surface with the build surface and the carrier defining a build region therebetween, and with the build surface in fluid communication by way of the semipermeable member with a source of polymerization inhibitor; (b) filling the build region with a polymerizable liquid, the polymerizable liquid contacting the build surface, (c) irradiating the build region through the build plate to produce a solid polymerized region in the build region, while forming or maintaining a liquid film release layer comprised of the polymerizable liquid formed between the solid polymerized region and the build surface, wherein the polymerization of which liquid film is inhibited by the polymerization inhibitor; and (d) advancing the carrier with the polymerized region adhered thereto away from the build surface on the build plate to create a subsequent build region between the polymerized region and the build surface while concurrently filling the subsequent build region with polymerizable liquid as in step (b). Apparatus for carrying out the method is also described.

The invention relates to a mold (200) for producing a foam cladding (120) made of plastic on a planar component (100) or for producing a foamed plastic part (120), comprising a mixing head (300) for producing liquid plastic from at least two components, at least one first cavity (240) for receiving the plastic in order to form the foam cladding (120) or to produce the foamed plastic part (120), a sprue channel (210) for connecting the mixing head (300) to the at least one first cavity (240), and a further cavity (220), which is formed at the transition of the sprue channel (210) to the first cavity (240) and widens the sprue channel (210). For automated cutting of a tag-like sprue, which would otherwise adhere to the foam cladding, the invention provides that a sprue cutter (400) having at least one slide (410) is movably mounted on the mold (200), which slide can be moved by means of at least one actuating cylinder (450) in the direction of the sprue channel (210) toward the first cavity (240) and, in an end position of the movement of the slide, closes off the first cavity (240) from the sprue channel (210) and/or from the further cavity (220) by means of at least one edge (414) and/or contour (412).

An apparatus for molding a part includes a plunger cavity, a plunger, and a mold cavity, wherein the plunger is oriented out-of-plane with respect to a major surface of the mold cavity, and first and second vents couples to respective first and second portions of the mold cavity. In a method, resin and fiber are forced into the mold cavity from a plunger cavity, and at least some of the fibers and resin are preferentially flowed to certain region in the mold cavity via the use of vents.
