The purpose of the present invention is to provide a lightweight composite material structure while suppressing a drop in strength. In a composite material structure, which is configured as a fiber-reinforced plastic composite material extending in one direction and having a plurality of holes (5) formed at intervals in a row in the one direction and which is subjected to a tensile load and/or a compressive load in the one direction, a peripheral region (3a) around the holes (5) comprises a first area (10) obtained by bending composite material, which is reinforced using continuous fibers that have been made even in the longitudinal direction, so that the center line of the width (W) of the composite material weaves between adjacent holes (5) and zigzags in the one direction. The tensile rigidity and/or compressive rigidity in the one direction of the peripheral region (3a) around the holes (5) is lower than the tensile rigidity and/or the compressive rigidity in the one direction of the other regions (3b) that surround the peripheral regions (3a).

A reaction plate includes a welded plastics planar laminate consisting of an aperture plate and a film, the aperture plate having at least one planar surface and a plurality of apertures in the planar surface of the apertured plate and the film being attached to the planar surface of the apertured plate around the or each aperture by welding. The welding is preferably laser or transmission welding. A method of forming such reaction plates using diode laser welding. An apparatus is provided for handling such reaction plates including performing polymerase chain reactions (PCRs) or primer extensions therewith.

Systems and methods for manufacturing laser-perforated nanoreinforced materials are disclosed. A honeycomb core may utilize a perforated top sheet and a microperforated overlay film coupled to the perforated top sheet. The perforated top sheet and/or the microperforated film may include thermally conductive nanomaterials. The perforations in the top sheet and the microperforations in the film may be laser drilled. The nanomaterials may dissipate heat generated by the laser drilling, allowing for increased perforation speeds.

A container for food products is defined by a cup-shaped basket, which is made of a first polymeric material, and is provided with a gripping handle connected to the basket in rotary manner by means of two coupling elements, which are made of a second polymeric material, and are welded to the basket itself.

A shaped sorbent is described comprising a plurality of layers of photopolymerised resin containing particles of a sorbent material. The shaped sorbent may be used as a getter for use in gettering one or more contaminants in a sealed enclosure.

A housing is provided. The housing includes a side wall having a plurality of holes and at least one reinforcing rib disposed on a surface of the side wall, wherein the holes are disposed on a side surface of the side wall, the at least one reinforcing rib extends along the edges of the holes, and the at least one reinforcing rib has a plurality of extending directions parallel to the surface, and the extending directions are different from each other. The side wall and the reinforcing rib are an integral structure, and the reinforcing rib does not cover the holes.

In order to simplify the manufacture of an insert part, which has two web structures, each of which forms a plurality of webs, it is proposed that the insert part is manufactured by a molding process in such a way that the two web structures touch each other in respective contact surfaces, but nevertheless remain separated from each other by a mold parting plane. This has the technical advantage that the respective outer contour of the webs of the respective web structure can be defined exclusively with a respective mold part without an offset of the respective other mold part having a negative effect on the shaping of the webs.

A screen making machine includes a table, welder assembly, and actuation assembly. The welder assembly includes: first and second nozzles, a pump that pumps air through each nozzle, and a roller. The first nozzle, second nozzle, and roller are positioned in line and spaced apart. The actuation system moves the welder assembly along each side of the frame. Hot air from the first nozzle elevates a temperature of the mesh and adjacent frame to a first elevated temperature, and subsequent flow of hot air from the second nozzle elevates them to a second elevated temperature, being above a melt temperature of the surfaces of the mesh and frame. The roller presses the melted mesh surface against the melted frame surface, to melt fuse them together. A top surface of the table is heated to thereby heat a second side of the frame, facilitating better welds.

A method of mechanically securing a first object to a second object, wherein the first object has a thermoplastic material in a solid state, the second object has a generally flat sheet portion having a second object edge. A third object is provided and arranged to provide an assembly including the first, second and third objects, in which assembly the second object edge is in contact with the thermoplastic material. Mechanical vibration energy is coupled into the assembly by means of a vibrating tool until a flow portion of the thermoplastic material due to friction heat generated between the second object edge and the thermoplastic material becomes flowable and flows around the second object edge to at least partially embed the second object edge in the thermoplastic material and the third object is caused to be embedded at least partially in the thermoplastic material of the first object.

An intermediate article for assembly to form a container, the intermediate article having a base which is polygonal in plan and having an annular peripheral edge with a plurality of edge portions surrounding a base wall structure, a plurality of wall elements around the base, each wall element being adjacent to a respective edge portion of the polygonal base, wherein each wall element has a pair of opposite outwardly extending edges having a sidewall structure therebetween, each outwardly extending edge comprising at least one member of a respective fixing mechanism for affixing adjacent outwardly extending edges of adjacent wall elements, wherein the sidewall and the base are composed of an injection moulded thermoplastic polymer, and a flexible sheet having a central part which is bonded to the base wall structure and a plurality of extending parts, each extending part being connected to, and extending away from, the central part, each extending part being bonded to the sidewall structure of a respective wall element, wherein each extending part is connected to the central part by a respective hinge part of the flexible sheet, whereby each wall element is hingedly connected to the base by the respective hinge part, wherein the wall elements can be hinged upwardly relative to the base to form a container having a sidewall which is polygonal in plan and defines a central concavity for packaging a product, wherein the sidewall has the plurality of wall elements which are connected in series to form an endless wall member extending upwardly from the base, each outwardly extending edge being affixed to an adjacent outwardly extending edge of an adjacent wall element by a respective fixing mechanism at a respective corner portion of the sidewall.
