The present invention relates to pharmaceutical dosage forms, for example to a tamper resistant dosage form including an opioid analgesic, and processes of manufacture, uses, and methods of treatment thereof.

An airflow control apparatus for a tenter oven including an entrance into which a film is conveyed and an exit from which the film is taken out, the airflow control apparatus having a box-shaped body installed adjacent to at least one or both of an upstream side in a film running direction of the entrance and a downstream side in the film running direction of the exit, includes: at least one pair of air blowing nozzles configured to blow air toward the film; at least one pair of upstream-side exhaust mechanisms configured to discharge air in the box-shaped body, and located on the upstream side of the air blowing nozzles in the film running direction; and at least one pair of downstream-side exhaust mechanisms configured to discharge the air in the box-shaped body, and located on the downstream side of the air blowing nozzles in the film running direction.

A weatherable, low heat build-up capstock system comprising an acrylic cap, a pigment system that is IR transparent to a greater degree than existing pigment systems, an IR reflective substrate, and an extrusion system for same.

An automated fiber placement (AFP) and in-situ fiber impregnation system includes a feeder, a resin dispenser, and a compaction roller. The feeder feeds a tow of fiber from a fiber supply toward a forming tool. The resin dispenser deposits resin onto the forming tool in front of the compaction roller. The compaction roller moves over the tow along the forming tool so as to press the tow onto the resin such that the compaction roller impregnates the resin into the tow a direction away from the forming tool via compaction forces immediately after the resin is deposited by the resin dispenser.

A method is disclosed for copying a surface texture of a surface carrier object to an air tight thermoplastic surface layer of an interior cladding component of a vehicle, by fixing the airtight thermoplastic surface layer inside the pressure chamber such that the airtight thermoplastic surface layer divides the pressure chamber into a first and second pressure chamber section by positioning the surface carrier object inside the pressure chamber with a positioning device in the vicinity of the airtight thermoplastic surface layer with the surface texture facing the airtight thermoplastic surface layer. By applying a pressure difference between the first and second pressure chamber section, the airtight thermoplastic surface layer is pressed on the surface carrier object, thereby copying a surface texture of a surface carrier object to an airtight thermoplastic surface layer. An interior cladding component of a vehicle, comprising an airtight thermoplastic surface layer is also disclosed.

There is disclosed a composite material lay-up head (20) for applying elongate fibre reinforcement material (14) to a tool (12), the head (20) comprising: at least one elongate tow guide channel (32) for guiding fibre reinforcement material (14) from a tow inlet (33) to a tow outlet (35) of the channel (32); and feed apparatus (36, 38) for feeding fibre reinforcement material through the at least one channel (32); wherein the or each channel (32) is provided with at least one nozzle (60) arranged so that in use a jet of gas can be delivered into the channel (32) so as to inhibit contact between fibre reinforcement material (14) in the channel (32) and the channel (32).

The present disclosure provides methods for additive manufacturing of a three-dimensional (3D) object, comprising preheating a feed comprising a polymer material to a temperature in excess of a glass transition temperature and below a melting point of the polymer material. The preheating may occur at a first location in an additive manufacturing apparatus. Next, the polymer material may be melted at a second location that is spatially distinct from the first location.

The invention discloses a straw brick dehumidifying and drying device, which includes a machine body, wherein a molding cavity is provided in the body, a sealing device is provided on the front side of the molding cavity, the sealing device includes a sealing plate, and the rotating device There is a rotating shaft, and a rotating wheel is fixed on the rotating shaft. Seven groups of storage devices are arranged on the outer periphery of the rotating wheel with the rotating shaft as the center. The storage device can place straw bricks. The rotatable rotating wheel drives the straw brick to rotate slowly, and the placement direction of the straw brick is always upward to maintain the stability of its placement. Secondly, the hot air is blown to the molding cavity through the rotation of the fan blades, and the hot air can be converted by the condensation device. It is discharged in a liquid state, and has the function of dehumidifying the molding cavity, thereby keeping the air in the molding cavity dry and improving the efficiency of preparing straw bricks.

An air flow controller includes: a box-shaped body cover that is disposed above and/or below a film running surface to be adjacent to an upstream side of an entrance of a tenter oven in a film running direction and/or a downstream side of an exit of the tenter oven in the film running direction, the box-shaped body cover extending in the film running direction and having a surface facing the film running surface and being open. The box-shaped body cover includes at least one partition structural body in the box-shaped body cover, the partition structural body extending in a width direction of the film and separating inside of the box-shaped body cover into a plurality of chambers, and each of at least two of the chambers is provided with an air discharge mechanism configured to discharge air in a corresponding chamber.

Disclosed is a method of repairing damage of an aircraft engine component made of or comprising weldable thermoplastic material, which method comprises welding of the weld filler material into an initially prepared damaged area. Also disclosed are the use of plastic welding technique for repairing damaged aircraft engine components made of weldable thermoplastic materials.
