A method manufacturing a spacer for a pipe-in-pipe system includes mixing aerogel particles with a polymer to form a mixture in which the particles are dispersed in the polymer. The resulting mixture is moulded and the polymer is solidified to form the spacer or a component of the spacer, in which the dispersed, particles are suspended in a matrix of the solidified polymer.

An object of the present invention is to propose a device capable of automatically insetting a tube into a bending die instead of doing so manually, even if the shape of a product exceeds two meters in length, the device comprising a bending die having a tube insetting portion, and a traveling body that includes a guide mechanism guiding a tube to an upper portion of the tube insetting portion, an auxiliary guide mechanism keeping the tube in the upper portion of the tube insetting portion, a insetting roll insetting the tube in the tube insetting portion, a pair of drive wheels rolling along lower rails, and a drive mechanism, wherein the traveling body moves and insets a tube into the bending die while having the auxiliary guide mechanism and the drive wheels grip the bending die.

Embodiments of the present invention provide a self-molding composite system for insulation and covering operations. The self-molding composite system may be cured to form any desired shaped for insulation and covering operations. The composite system comprises one or more layers that may create a rigid layered composite when cured. The one or more layers of the composite system may include a base layer that is a braided, knit, or non-woven fiber based substrate, an interstitial matrix layer, and customizable top coat. The customizable top coat may be a solvent based polymer solution that includes various additives that may include color pigments, additives for additional abrasion protection, additives for thermal protection, and/or additives for creating various textures or visible appearances to the composite system.

Apparatus and methods for manufacturing compostable, biodegradable drink straws from polyhydroxyalkanoate (PHA) material are disclosed herein. Such apparatus may include a hopper that contains raw PHA material, an extruder that receives the raw PHA material from the hopper and produces extruded PHA material, one or more waters baths that cool the extruded PHA material, a puller that pulls a tubular stream of PHA material through the system, and a cutter that is configured to cut the stream of PHA material into finished straws. The finished straws may be soil- and marine-biodegradable, as well as home- and industrial-compostable.

The present disclosure relates to a fibre reinforced polymer (FRP) tube, the tube comprising a plurality of concentric layers of an FRP material forming a shell of the tube. At least one blind threaded longitudinal bolt hole is provided from a transverse end surface of the shell. The bolt hole extends in at least three of the plurality of layers, a middle layer encompassing a plane passing through a center of the bolt hole, an inner layer encompassing a plane of an innermost extent of the bolt hole, and an outer layer encompassing a plane of an outermost extent of the bolt hole. The fibre filament of each of the inner and outer layers has been wound at a first angle to the longitudinal axis and the fibre filament of the middle layer has been wound at a second angle to the longitudinal axis.

A bonded multilayer article including: (a) at least one first layer of a silicone-containing rubber substrate material bonded to (b) at least one second layer of a substrate material bondable to the first layer; wherein at least a portion of the surface of the first layer is activated for adhesion to increase the bond strength of the first layer to a second layer such that the bond strength of the first layer bonded to the second layer is increased; and a process for producing the above bonded multilayer article.

The invention concerns an elastic element (100) made of a plastic material for a device (1) for dispensing fluids (L), comprising a tubular body (129) that develops around a main longitudinal axis (X), comprising a main portion that develops according to a spiral-shaped pattern and extends longitudinally between a first end portion (100a) and a second end portion (100b) opposite the first end portion (100a). One of the first and second end portions comprises a first projection (151) extending from the internal surface of the tubular body (129) towards the inner space defined by the tubular body (129). The invention furthermore concerns a method for making an elastic element (100) through an injection moulding process, a mould (200) for making an elastic element (100).
