An acoustic attenuation panel for a propulsion assembly includes an acoustic front skin having perforations, and a central structure formed from partitions arranged perpendicularly in order to make up cells, wherein the front skin and the central structure form the panel which is made as a single piece and is provided for directly covering a surface of an element of the propulsion assembly forming a rear skin which closes the cells of the central structure at the rear.

A method for forming a perforated membrane includes providing a mold having at least a first set of a plurality of rods extending to at least a first height from a base of the mold, introducing a curable material into the mold in an amount such that a height of the curable material from the base of the mold is less than or equal to the first height so that the first set of the plurality of rods are within the curable material and extend to or past the height of the curable material in the mold, curing the curable material, dissolving the first set of the plurality of rods to thereby form perforations in the cured material and removing the cured material having the perforations from the mold.

Three-dimensional decorative articles are produced from blanks of heat-shrinkable plastic sheet material, using a mold base having an outer surface with a recess over which a blank is placed, and a convex mold insert that moves into the recess by gravity as the blank softens and cooperates with the interior wall of the recess to shape the sheet material into a three-dimensional decorative article. A guide peg extends outward from the bottom of the recess past the outer surface of the mold base and extends through a hole formed in the blank, and through a guide hole in the mold insert to support the mold insert before heating and to guide the mold insert as it moves into the recess of the mold base.

A casting mold for producing a casting having a front side and a rear side from a curable casting compound, including at least a first mold part shaping the front side and a second mold part shaping the rear side, the mold parts together delimiting a casting cavity. A slide device, provided on one of the mold parts, includes a slide portion that can be driven into the casting cavity and on which a detachable insert part is or can be arranged. The insert part is able to be moved abutting against the opposite mold part and is able to be embedded into the curing casting compound, and is detached from the slide portion when the latter is moved back.

A hybrid mandrel for forming a composite part may comprise a core and a sleeve located around the core. The core may include a rigid material. The sleeve may comprise an elastomeric material. The part may be formed by locating the hybrid mandrel in an injection mold, depositing a molten resin around the hybrid mandrel, curing the molten resin; and removing the hybrid mandrel.

An extruded part is formed by extrusion of at least one polymer melt, wherein the polymer melt or polymer melts has/have two melt fronts, which form two material inner edges of the extruded part when the polymer melt or polymer melts is/are in the solidified state; the two material inner edges are integrally bonded to each other and define a linear binding seam of the extruded part. The binding seam is situated in a connection region of the extruded part; andthe extruded part has at least one fiber grid, which is situated in the connection region of the extruded part and is connected to the extruded part such that the fiber grid bridges the two material inner edges. The extruded part may be a part of a battery housing for a traction battery.

A fluid manifold may include a body that may include a proximal end, a distal end, and a primary manifold component extending from the proximal end of the body to the distal end of the body and enclosing a primary channel. The fluid manifold may further include at least one auxiliary manifold component diverging from the primary manifold component and enclosing an auxiliary channel connected to the primary channel at a primary channel exit port. The fluid manifold may further include at least one compression valve region disposed along the body of the manifold where the compression valve region may be operable between an open position and a closed position.

A method for making an object (2) from plastic material, having a wall (21) and a through hole (22) formed in the wall (21), comprises the following steps: preparing a dose (20) of extruded plastic material; preparing a mould (1), having a first half mould (11) and a second half mould (12), mutually movable along a longitudinal axis (A1), wherein the first half mould (11) includes a body (111) and a plunger (112), the plunger (112) being movable relative to the body (111) between a retracted position and an advanced position; positioning the dose (20); closing the mould (1) to form a closed moulding space (V); moving the plunger (112) from the retracted position to the advanced position to squeeze the dose (20) so that the plastic material is forced to occupy the moulding space (V).

A multi-piece mold for use in a method for making a slurry distributor includes a plurality of mold segments adapted to be removably secured together. The mold segments are configured such that, when the mold segments are assembled together, the assembled mold segments define a substantially continuous exterior surface adapted to be a negative image of an interior flow region of a slurry distributor molded thereupon. Each mold segment has a maximum cross-sectional area in a plane substantially transverse to a direction of movement of the mold segment along a removal path out of a respective opening of the molded slurry distributor. The maximum cross-sectional area of each mold segment is up to about 150% of the smallest area of the interior flow region of the molded slurry distributor through which the mold segment traverses when moving along the respective removal path.

An interlocking construction block system comprising a family of blocks that interlock along three axes, including a left/right axis, a front/back axis, and an up/down axis. The family of blocks are self-aligning and do not require skilled labor or mortar to create a structure of any length, width, height, or shape. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights and stresses. The disclosed blocks can be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement. The blocks may comprise channel openings to allow for plumbing, electrical, and structural reinforcements in the structure and may each be reinforced with an internal mesh cage.
