A device (10, 40, 50, 60) and a related method for selectively applying pressure to a fiber impregnated resin, where the device includes a thermally expansive material having a body (12) which extends in an axial direction from an upper terminal surface (14) to an opposite lower terminal surface (16), a first retaining member (18) affixed to one of the upper terminal surface and the lower terminal surface, wherein the first retaining member is configured to limit expansion of the thermally expansive material in a direction substantially perpendicular to the axial direction when the thermally expansive material is subjected to an increase in temperature.

A mould comprises a mould body (1) for forming therearound a body (60) with a body cavity which is accessible via an opening. The mould body is assembled from a set of mutually cohesive body parts (30,40). The body parts (30,40) are mutually releasable and removable from the body via the opening. An inflatable body (60) can be manufactured with the mould. The inflatable body (60) comprises a wall of elastomer material, which wall at least in an inflated state of the body bounds a body cavity accessible through a wall opening. The body is inflatable by filling the body cavity with a fluid.

An undercut processing mechanism includes: a core pin for forming an inner circumferential surface of a tubular projection; a slide core for forming an outer circumferential surface of the tubular projection; a sliding piece for causing the core pin to advance/retract in an axial direction of the tubular projection; a retaining piece for causing the sliding piece to advance/retract; a holder for accommodating the retaining piece such that the retaining piece can advance/retract; and a movement amount restrictor for restricting a movement amount of the core pin. The retaining piece is operable to advance/retract in a state where a stationary die and a movable die are closed. When the core pin retracts in conjunction with retraction of the retaining piece and a movement amount of the core pin reaches a restricted distance, the core pin and the slide core retract together, thereby allowing an undercut portion to be demolded.

A machine for disassembling a lens mold assembly including a first mold part, a second mold part, and a molded-lens sandwiched therebetween. The machine includes a centering unit to center the lens mold assembly. The machine includes a disassembling module having a mold engagement mechanism to engage the first and second mold parts to clamp and move the lens mold assembly. The disassembling module includes a molded-lens holder mechanism having at least two clamping members to clamp the molded-lens of the lens mold assembly. The machine includes an alignment guidance module to detect relative positions between the molded lens of the lens mold assembly and the molded-lens holder mechanism to align the molded lens for clamping by the molded-lens holder mechanism. The mold engagement mechanism is configured to hold the first and second mold parts individually and to separate the first and second mold parts from the molded lens.

According to an aspect, a method of assembling a mandrel includes assembling a plurality of members via interlocking features arranged at opposing edges of each member of the plurality of members to form a compartment, the assembled members having a collective outer surface that conforms to an inner surface of the spar. A support member is inserted into the compartment formed radially inward from the assembled members, the support member making contact with a portion of each member of the plurality of members.

A jig includes mold parts that have a contact surface of a cylindrical part of a material to be molded having a shape complying with the inner peripheral surface of the cylindrical part and are arranged in a direction crossing one direction; a bladder that is provided on a side opposite to the contact surfaces of the plurality of mold parts relative to the mold parts, capable of accommodating a fluid therein, and expandable/retractable according to a pressure of the accommodated fluid; a joining part that joins the plurality of mold parts and the bladder; and a connection part that connects a one-side mold part and an another side mold part adjacent to the one-side mold part among a plurality of mold parts to each other and restricts an interval between the one-side mold part and the other-side mold part in a direction crossing the one direction with a prescribed range.

A reusable mold membrane is provided for forming an outer mold during a process to encapsulate a target object in a substance, the mold membrane comprising: a cylindrical membrane body comprising a resiliently deformable material, wherein an inner diameter of the cylindrical membrane body is less than an outer diameter of the target object provided on an outer surface of a cylindrical carrier object, when the membrane body is in an un-deformed state; and a plurality of manipulation structures provided on an outer part of the membrane body, each of the plurality of manipulation structures configured to be manipulated by application of mechanical force to control the space within the membrane body by controlling the amount of deformation of the membrane body. There is also disclosed a method for use during a process to encapsulate a target object in a substance.

A cascade assembly for a jet engine thrust reverser comprising an inflow cascade, an outflow cascade, and fasteners. The inflow cascade has a plurality of inflow vanes, a plurality of inflow strongbacks, and a front inflow flange. The outflow cascade has a plurality of outflow vanes, a plurality of outflow strongbacks, and a front outflow flange, wherein each of the plurality of outflow strongbacks are parallel to each other. The fasteners extend through the front inflow flange and the front outflow flange.

A device (20) for installing a tubular junction sleeve inside a pipe (1), having a mandrel (20a) of longitudinal axis (XX) supporting on its surface at least a first peripheral chamber (21) having a wall (21a) that is radially expandable by inflation. The first wall including at least one electrical connector (21b) suitable for being connected to one end of said heater wire. The connector being connected to an umbilical (24) including at least a compressed air feed duct for inflating the first chamber and an electrical power supply duct connected to the electrical connector.
