Abstract: Process for producing single layer and multilayer polyolefin foam pipes with improved compression resistance having a polyolefin foam layer which consists of mixtures of modified propylene polymers having strain hardening behaviour or propylene homopolymers with a stereospecificity index >98% or propylene copolymers with a stereospecificity index of the homopolymer matrix of >96%. The polyolefin foam pipes include coated steel pipes for transporting crude oil or gas products or district heating applications, single layer pipes for insulation purposes and for non- or low-pressure applications and multilayer plastic pipes for the transportation of hot or cold fluids.

Abstract: Methods for defining engineering requirements in an electronic environment are disclosed. In one embodiment, a method includes providing at least one of a set of master requirements and a set of version requirements to be applied to the electronic product definition, and referencing an electronic reference document from at least one of the set of master requirements and the set of version requirements, the electronic reference document including one or more particular engineering requirements to be applied to the electronic product definition. Alternately, a method includes defining a callout linked to the at least one of the set of master requirements and the set of version requirements, the callout being adapted to supercede a conflicting engineering requirement set forth in at least one of the set of master requirements and the set of version requirements.

Abstract: An elongated centering stud is adapted for attachment to a wheel mounting member applicable for securing a vehicle wheel to a spin balancer. The centering stud includes a head adapted for engaging the vehicle wheel, a body extending from the head, and a base formed with the body opposite the head. The base is adapted for engaging the mounting member. A reduced-diameter connecting end projects from the base, and is adapted for being inserted into a stud-receiving hole formed with the mounting member. The centering stud flexes relative to the mounting member, such that any force acting on the centering stud is distributed along a length of the stud.

Abstract: Methods and systems for usage-based product definition are disclosed. In one embodiment, a method includes instancing one or more usage-based product definition inputs, and assessing at least one of an applicability expression, an engineering requirement, and a manufacturing availability expression. The method further includes generating the product definition based on at least some of the usage-based product definition inputs, applicability expressions, engineering requirements, and manufacturing availabilities. In alternate embodiments, the instancing may include transforming a coordinate system of a component from a component-centered coordinate system to a product-centered coordinate system.

Abstract: A system and method for providing tool operators in a manufacturing environment with clear and accurate tooling information increases tool operators' efficiency and reduces possibilities of errors. An output device and an input device are coupled to a processor. A tool operator enters a product option and a line number in the input device. The processor automatically selects a previously-defined build plan based on the entered information. The processor outputs the selected build plan to the output device. The outputted build plan includes tool information based on the entered product option and line number. The system communicates with a manufacturing system and a tool design system over a network.

Abstract: A data structure and computer-program product for providing tool design and instructions in a dynamic manufacturing environment are provided. The data structure includes a plurality of objects for abstracting tool resources. Each object represents all changes that relate to one of a tool or a part of a tool. The instances of the objects are based on product information and are generated for associated instructions for tool usage in the manufacturing environment. The product information includes information identifying configuration of the product and a definition of a functional deliverable of the product. The information identifying configuration of the product includes product option information. The functional deliverable of the product includes production line number where the object applies.
