An ostomy appliance includes a waste collection bag that is molded to form a front wall that continuously extends to form both a side wall and a rear wall. The rear wall is spaced apart from the front wall when the waste collection bag is empty. A bottom of the waste collection bag is defined by a curved bottom wall that continuously extends from both the front wall and a rear wall. The waste collection bag is formed to include a longitudinal curvature within at least one of the front wall and the rear wall, and a connector is integrally molded into the rear wall of the waste collection bag around a waste inlet.

The presently disclosed subject matter is directed to a golf ball providing improve play characteristics. The disclosed golf ball includes an outer cover comprising a plurality of divots. The disclosed golf ball further includes a central core comprising one or more lightweight materials, such as aerogel. The combination of the lightweight core and the unique divots enable the golf ball to go farther and straighter when hit by the golfer, thereby providing increased performance.

An arcuate sweep elbow pipe connector section is disclosed as part of the piping system used to deliver water from a source to a fire sprinkler head. The arcuate sweep elbow pipe connector section is integrally formed at one end with a first connecting section and integrally formed at a section end with a second connection section. The connecting sections are positioned ninety degrees relative to each other and the arcuate sweep elbow pipe connector section optimizes water flow through both connecting sections.

The present invention relates to the use of thermoplastic polymer compositions for impregnating reinforcing materials in the form of fabric or industrial fabrics for the manufacture of composite materials. The field of the invention is that of composite materials as well as molding/consolidation processes and obtained parts. The invention more particularly relates to a method of manufacturing a composite article by injection molding comprising at least the steps of introducing at least one reinforcement fabric into a preheated mold, partial closure of the mold, a temperature rise step of the mold, optionally a step of maintaining the temperature of the mold before injection of a thermoplastic polymer composition, a step of injecting a thermoplastic polymer composition into the mold, a step of mold closure to the final part thickness allowing the flow of the resin through the reinforcing fabric, a cooling step and a recovery step of the obtained composite article.

A moulding material contains to an extent of at least 50 wt % of the combination of the following constituents: a) 80 to 95 parts by mass of a polyamide component comprising a1) 70 to 100 parts by wt of PA PACMX and a2) 30 to 0 parts by wt of a linear aliphatic polyamide, b) 4 to 19 parts by mass of a core-shell impact modifier, and c) 1 to 5 parts by mass of a functionalized styrene-ethylene/butylene-styrene block copolymer as an impact modifier, wherein the parts by mass of a), b) and c) sum to 100. The moulding material has a high transparency and a very good notched impact strength.

A method for the design, manufacture, and assembly of modular lattice structures composed of cuboctahedron unit cells.

A thermoplastic resin composition of the present invention comprises: about 100 parts by weight of a polycarbonate resin; about 10 to about 40 parts by weight of a polyester resin; about 0.1 to about 1.0 parts by weight of a chain extender; about 50 to about 80 parts by weight of glass fibers; about 10 to about 25 parts by weight of a phosphorus flame retardant; and about 1 to about 7 parts by weight of a modified polyolefin, wherein the weight ratio of the polyester resin and the chain extender is about 1:0.01 to about 1:0.06. The thermoplastic resin composition is excellent in dimensional stability, flame retardancy, impact resistance, and the like.

Examples are disclosed herein that relate to creating undercuts and other complex geometries in an injection molded article. One example provides a method of forming an injection molded article comprising an undercut structure, the method comprising inserting an insert piece into a mold for forming the molded article, the insert piece comprising sacrificial material, injection-molding the molded article, thereby incorporating the insert piece into the injection molded article, and machining the insert piece to form the undercut structure from the sacrificial material.

An article of manufacture and a method are disclosed including a multi-layered knee pad including an outer shell and other layers forming high sidewalls, the height of which depends on the internal width of the knee pad. The outer shell may also have an array of recesses on its outer convex surface. The other knee pad layers include one or more foam layers on the concave side of the outer shell, one or more gel layers surrounded by the foam layers, and a fabric sheet covering the foam layers on the concave side of the outer shell. The knee pad is manufactured using an injection mold to form the foam layers. The knee pad is customizable with respect to size, firmness, and structure. The knee pad may be customized by varying the layer's characteristics such as material and dimensions as well as the size and location of the recesses.

Provided are a resin composition and masterbatch pellets, which enable a molded resin composition product to improve both flexural modulus and Izod impact strength, and a molded resin composition product having both improved flexural modulus and improved Izod impact strength, and a method for producing the same. The resin composition includes 45 to 95 mass % of an olefin polymer, 1 to 50 mass % of fibrous basic magnesium sulfate, 0.00001 to 0.8 mass % of spherical silica particles, and 0.1 to 10 mass % of a lubricant. Also, the masterbatch pellets are for production of the resin composition by kneading the masterbatch pellets with a diluent containing olefin polymer, and the masterbatch pellets contain 10 to 50 mass % of an olefin polymer, 35 to 80 mass % of fibrous basic magnesium sulfate, 0.00005 to 5.0 mass % of spherical silica particles, and 0.5 to 10 mass % of a lubricant.
