Mold including a first shell having a cavity, a second shell having a projection, and an intermediate shell having a projection suitable for being coupled in the cavity of the first shell and a cavity suitable for being coupled with the projection of the second shell. The second shell includes a first injection channel extending from an inlet hole in a side wall of the second shell to an outlet hole in the projection of the second shell. The intermediate shell has a second injection channel extending from an inlet hole in a side wall of the intermediate shell to an outlet hole in the projection of the intermediate shell.

A tire vulcanizer is disclosed including a sector arranged with respect to a side plate with a high degree of positioning accuracy. The tire vulcanizer includes: the sector that shapes a tread of a tire; a segment to which the sector is fixed and causes the sector to move in a tire radial direction; a bolt that fixes the sector to the segment; a ring-shaped jacket ring provided on an outer side in the tire radial direction of the segment; paired upper and lower side plates that shape sidewalls of the tire; and mold parting surfaces defined by the sector and the paired upper and lower side plates. Mold inner ends of the mold parting surfaces are arranged on the tread, and the mold parting surfaces extend outward in the tire radial direction from the mold inner ends.

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.

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 apparatus comprises a mould part having a forming chamber and a filling device for filling the forming chamber with a mouldable material. The filling device comprises an entry duct for a flow of mouldable material and air and a preliminary chamber communicating with the forming chamber. The entry duct opens into the preliminary chamber in a position such as to send the flow of mouldable material and air towards the forming chamber with a helicoidal movement, so as to separate the mouldable material from the air.

An infusion terminal block that secures to a vacuum bag and receives a resin hose includes a prismatic body, a tube opening, and a plurality of channels. The tube opening that receives the resin hose concentrically traverses through the prismatic body from a bottom surface of the prismatic body. A stopper is laterally connected within the tube opening to stop the resin hose from touching a laminated surface. The plurality of channels traverses into the prismatic body from the bottom surface and in fluid communication with the tube opening. Resultantly, resin that is discharged through the resin hose travel through the tube opening and radially discharged into fibers thus forming the laminated surface. The infusion terminal block can optionally include a clip to secure the prismatic body to the laminate and other ancillary products.

Mold inner ends of the mold parting surfaces are arranged on the tread, and the mold parting surfaces extend outward in the tire radial direction from the mold inner ends.

A mold device includes a first mold side configured to receive a substrate in a cavity and to couple with a second mold side, the first mold side including a sidewall and a gate, wherein the substrate is recessed in the first mold side at a substrate recess depth of 2 mm or greater, and wherein the substrate recess depth is a distance along the sidewall between a bottom of the gate and a surface of the substrate in a direction perpendicular to a line between the gate and a middle of the surface of the substrate, and wherein the bottom of the gate and a top of the sidewall are at distinct heights from the surface of the substrate.

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.
