One aspect of a method of manufacturing a honeycomb core includes positioning a first thermoplastic columnar cell adjacent a second thermoplastic columnar cell, modifying a thermoplastic property of the first thermoplastic columnar cell, wherein the modified thermoplastic property permits joining a circumferential surface of the first thermoplastic columnar cell to a circumferential surface of the second thermoplastic columnar cell. The method also includes joining the circumferential surface of the first thermoplastic columnar cell having the modified thermoplastic property to the circumferential surface of the second thermoplastic columnar cell resulting in the honeycomb core.

A method protects a field joint of a pipeline, where chamfered edges of thermally-insulating parent coatings on conjoined pipe lengths are in mutual opposition about a longitudinally-extending gap. The method includes manufacturing an hourglass-shaped inner layer around the pipe lengths, which layer may be moulded. The inner layer extends longitudinally along the gap between the chamfered edges and at least partially overlies the chamfered edges. A thermally-insulating solid insert is assembled from two or more parts to lie in the gap surrounding the inner layer, and pressure is applied radially inwardly from the insert to the inner layer. An outer layer of molten material is manufactured around the insert to form a watertight barrier and to form one or more melted interfaces with the inner layer. Corresponding field joint arrangements are also disclosed.

The disclosed technology includes a catheter or sheath assembly and a method for manufacturing same. The manufacturing process includes obtaining a catheter or sheath having a distal end and a proximal end, and obtaining a hub pre-formed separately from the catheter or sheath. The hub can include a pre-formed receptacle portion configured to receive a portion of the catheter or sheath. A portion of the catheter or sheath can be inserted into the pre-formed receptacle portion of the hub. The receptacle portion can be melted to a semi-fluid state and can be compressed against the portion of the catheter or sheath in the hub.

A method of welding a sleeve (10) to a tube (20) includes putting onto end portions (11) of the sleeve (10) respective protective elements (40), of a material that cannot be fused with the materials of the sleeve (10) and of the outer coating (24) of the tube (20); applying on each end portion (11) of the sleeve (10) covered by a protective element (40) a respective heat-shrink element (30); supplying each heat-shrink element (30) with a quantity of heat (Q) which by heating it causes it to shrink and compress the respective end portion (11) of the sleeve (10) against the tube (20), where this quantity of heat (Q) is transmitted to the end portion (11) of the sleeve (10) to obtain a welding of the sleeve (10) to the tube (20) and produce a device (1) comprising the tube (20) with the sleeve (10).

An automated heat shrink device, useful for forming a connection between two tubular sections having a polymeric outer surface jacket, for example, a connection between two sections of a district heating pipeline, and a method of use thereof. The device is configured such that it requires minimal clearance to either side of the pipeline when being used.

Bag-sealing apparatus is provided for heat-sealing a bag. The apparatus has a heater arrangement operable to apply heat to heat-seal an open end of the bag. A bag detector detects the location of the bag relative to the heater arrangement. The heater arrangement is formed of plural heater portions. The heater arrangement is operable such that only the or each heater portion that overlies the bag as detected by the bag detector is caused to operate to apply heat to the bag.

Method, and apparatus, for applying a heat-activated double-sided adhesive tape (10) to a support (20) by: activate by heating the double-sided adhesive tape (10) with laser light from at least two different laser light emitters (30), salid emitters each compörising an optical collimator (31) adapted to project a cylindrical light beam (33), and bringing into mutual contact said activated double-sided adhesive tape (10) with said support (20) in a contact zone so they join.

The invention relates to a device comprising a first fixing element, a further fixing element and a folded planar composite; wherein the first fixing element comprises a first fixing surface and the further fixing element comprises a further fixing surface; wherein the folded planar composite is at least partially fixed between the first fixing surface and the further fixing surface; wherein the folded planar composite comprises a first composite region; wherein the first composite region comprises a first layer sequence comprising a first composite layer comprising a first carrier layer, a second composite layer comprising a second carrier layer, a third composite layer comprising a third carrier layer and a fourth composite layer comprising a fourth carrier layer; wherein in the first composite region the second composite layer is joined to the third composite layer and the third composite layer is joined to the fourth composite layer; wherein in the first composite region the third carrier layer is characterised by a smaller layer thickness than in each case one selected from the group consisting of the first carrier layer, the second carrier layer and the fourth carrier layer or a combination of at least two of these; wherein the first fixing surface or the further fixing surface or both comprises a recess comprising a first recess region; wherein the first composite region is located at least partially between the first recess region and the first fixing surface or the further fixing surface.

A method of manufacturing an ink jet print head capable of bonding the printing element substrate to the support surface with high precision in a reduced period of time is provided. For this purpose, raised flat portions are formed in the support surface of the supporting member to provide in an adhesive layer between the printing element substrate and the supporting member a portion of the thermosetting adhesive that is thinner than others. After the relative positions of the printing element substrate and the supporting member are adjusted, the thin portions of the adhesive layer are hardened. This enables the printing element substrate to be bonded to the supporting member in a relatively short period of time. As a result, if there are undulations on the support surface, the printing element substrate can be bonded to the supporting member with high precision, improving the mass productivity of the print head.

A joining method for joining a resin member and a metal member by heating is provided. Joining of the resin member and metal member is performed by heating a joining interface of the resin member and metal member to a temperature in a range of equal to or higher than a decomposition temperature of the resin member and lower than a temperature at which gas bubbles are generated in the resin member and by cooling a surface of the resin member on the opposite side from a joining surface thereof with the metal member to a temperature that is lower than the melting point of the resin member.
