In one example, a porous tube assembly is described. The porous tube assembly comprises a material and at least one tube. The material is configured for an additive textile manufacturing process, and the at least one tube is integrated with the material by the additive textile manufacturing process. The at least one tube defines a hollow channel and one or more perforations that extend between the hollow channel and an outer surface of the at least one tube.

A method of bonding a first object to a second object includes the steps of: providing the first object including thermoplastic material in a solid state, providing the second object including a proximal surface, applying a mechanical pressing force and a mechanical excitation capable to liquefy the thermoplastic material until a flow portion of the thermoplastic material is flowable and penetrates into structures of the second object, and stopping the mechanical excitation and letting the thermoplastic material resolidify to yield a positive-fit connection between the first and the second object. The second object has a region of low density, wherein the protrusion penetrates the region of low density at least partly before the thermoplastic material is made flowable, and wherein the first object includes a protruding portion after the step of letting the thermoplastic material resolidify, the protruding portion at least partly penetrates the region of low density.

The present invention provides a life jacket. In an embodiment, the life jacket includes a jacket member; and an air blowing member which is provided in the jacket member to inject air to the jacket member, wherein the air blowing member includes a base part coupled with the jacket member; and a tube part extending from the base part, wherein a flexible portion is formed in a part or the entire of the tube part.

A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components. The insert may be bonded to the frontal pocket using an adhesive impregnated within a glass fiber weave.

The present invention is directed to a side-sealed open mesh fabric bag having one or more multi-layer seam structures. At least one side seam of the bag comprises a plurality of folded layers of the bag's fabric bonded together within a seam structure by a plurality of seal portions. At least one of those seal portions is a sacrificial seal configured to at least partially give from the seam structure, whilst one or more other seal portions of the seam structure remain intact. The sacrificial seal provides the bag with volumetric flexibility, whilst the remaining seam structure provides an improved seam strength.

The present invention relates to a pig for use in a system for lining ducts such as water or sewage pipes or electrical ducts or gas pipes. The pig is insertable at least partly within a fabric liner sleeve located in a duct such as a water or sewage pipe and is capable of heating the liner sleeve in situ in the duct to melt or soften thermoplastic material of the liner sleeve to subsequently form, on cooling of the melted thermoplastic material, a rigid liner in the duct. A pig for fitting a liner to the inside of a pipe, comprising a pig body defining a longitudinal axis in a longitudinal direction from a front portion to a rear portion; a gas supply port in the front portion; a gas outlet diffuser forming part of the rear portion; a heating chamber in the pig body forming a flow path from the fluid inlet to the outlet diffuser; and a heater within the heating chamber, wherein the outlet diffuser comprises a plurality of channels, each channel comprising an inlet facing the front portion in the longitudinal direction and an outlet extending radially outwardly from the longitudinal axis.

A joiner for preparing a barn curtain comprising a welding machine. The joiner for preparing the barn curtain further comprising a non-transparent panel feeder feeding non-transparent panel material to the welding machine. The joiner for preparing the barn curtain further comprising a transparent panel feeder feeding transparent panel material to the welding machine. The joiner for preparing the barn curtain further comprising a support roller supporting the feeding of the non-transparent panel feeder and the transparent panel feeder. The joiner for preparing the barn curtain further comprising a barn curtain spooler receiving the barn curtain output from the welding machine.

Exclusion devices for anatomical structures, and related instruments and related methods, are disclosed. An exclusion device for an anatomical structure may include a first beam, a second beam, and/or a first spring operatively coupled to the first beam and the second beam to exert a closing force on the first beam and the second beam. The first spring may be generally U-shaped and/or may include a first end portion and a second end portion generally opposite a connecting portion.

A method for joining two objects by anchoring an insert portion provided on a first object in an opening provided on a second object. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. During the step of inserting the insert portion in the opening and/or during anchorage a clamping force is applied to opposing surfaces of the second object to prevent the second object from cracking or bulging.

Disclosed herein is a method of manufacturing a headlining, using a moisture-curing adhesive that can be molded at a relatively low temperature and enables energy saving by not requiring a condition in which bonding surfaces are preheated to an excessively high temperature. A headlining manufactured thereby the same method is also disclosed. The method includes coating a fabric with a moisture-curing adhesive, curing the moisture-curing adhesive by spraying water onto the moisture-curing adhesive, forming a headlining member by putting the fabric coated with the moisture-curing adhesive on a substrate after the curing, and pressing the headlining member so that the fabric and the substrate are bonded to each other and the headlining is shaped at the same time, after the forming.
