A composite rotatable assembly for an axial flow compressor comprises a spool having a plurality of blade assemblies arranged in stages on the spool and attached thereto by a wound band. Each blade assembly comprises a blade and a base, with the base having a forward tang extending axially forward of a leading edge of the blade and an aft tang extending axially aft of a trailing edge of the blade. The band is wound over at least a portion of the forward and aft tangs of the plurality of blade assemblies to hold the blade assemblies to the spool under centrifugal loading. An abradable layer may be added over the wound band.

Disclosed herein are simulated fibrous tissue models of anatomical parts for surgical training. The non-dissolvable simulated fibrous tissue model is made of a polyvinyl alcohol (PVA) and fibrous material composite to simulate realistic tissue properties and behaviors. The simulated fibrous tissue model may be a standalone model of an anatomical part or may be used in a complementary anatomical simulation kit to provide a more comprehensive training approach.

Provided is a reactor grade polypropylene suitable for injection molding applications comprising within a range from 0 wt % to 4 wt % ethylene and/or C4 to C12 -olefin derived units, the polypropylene produced from a single catalyst and single stage polymerization process, and having a melt flow rate (MFR, 230 C./2.16 kg) greater than 10 g/10 min, and a 1% secant flexural modulus of at least 250 kpsi (1720 MPa).

The present invention provides a wearable medical support for delivery of a treatment to the nose of a subject comprising: a nose mask formed from a heat moldable sheet of thermoplastic material, said nose mask comprises an aperture dimensioned to fit the nose of the subject, said aperture is flanked by two flaps whereby each flap is configured to be in contact with at least part of a lateral side of the nose; and a device configured to close fit said aperture, said device is provided at one end with an opening for receiving the nose and at the other end with at least one coupling suitable to be connected to one or more tubes for delivery of the treatment to the nose. The present invention further provides a sheet of heat moldable thermoplastic material for molding a mask directly on a subject's nose.

Flares with consumable weights connected to a forward end of the grain of the flare are disclosed. Also disclosed are consumable weight components for flares. The consumable weight components include a metal material within a matrix. Also disclosed are methods for fabricating a flare and methods for using a flare. Use of the consumable weights in the flares may reduce the amount of debris falling to ground.

Described are methods for manufacturing a plastic component, in particular a cushioning element for sports apparel, a plastic component manufactured with such methods, for example a sole or a part of a sole for a shoe, and a shoe with such a sole. The method for the manufacture of a plastic component includes loading a mold with a first material includes particles of an expanded material and fusing the surfaces of the particles by supplying energy. The energy is supplied in the form of at least one electromagnetic field.

An ultrasound-detectable polymeric device that offers superior visibility of the body of the device and decreased ultrasound angle dependence through the use of microcavities and methods of manufacturing thereof is disclosed. These microcavities enable superior ultrasound visualization due to diffuse reflection of sound waves when compared to solid polymeric objects, ensuring that a strong signal is received at the source of the ultrasound transducer and providing strong image contrast throughout the entire cross-section of the implant that is also robust to variable angles of insonation.

Cast films made from metallocene-catalyzed polyethylene polymers, optionally, with other polymers, and processes for making the same, are disclosed.

Provided herein is a method for preparing antimicrobial thermoplastic resins and products thereof.

A magnetic encoder in which a support member and a plastic magnet do not adhere to each other is manufactured using a mold. The plastic magnet has a turning molded portion on the outer circumferential side thereof. The gate of the mold is an inner-diameter-side disk gate and a length L thereof in the axial direction is in a range of 0.2 mmL0.6 mm. The tensile strength of the material of the plastic magnet is 65 MPa or more and the Young's modulus thereof is 4000 MPa or more and 15000 MPa or less. The method includes a step of opening the mold and placing the support member as an insert object in the mold, and a step of closing the mold and injecting a melted material of the plastic magnet into a cavity through the disk gate.
