Abstract: A method of manufacturing an article by hot pressing and ultrasonically inspecting the article comprises forming and filling a canister with powder material and evacuating and sealing the canister. Heat and pressure are applied to the canister to consolidate the powder material to form the article. The article within the canister is ultrasonically inspected by moving a transducer over the whole of the canister. The position of an interface between the article and the canister, and the thickness of the canister, at each position on the surface of the canister and if there are defects within the article are determined. The canister is then removed from the article by machining the canister using a machining tool, the movement of the tool is controlled such that at each position of the canister the tool removes the determined thickness of the canister for the corresponding position on the surface of the canister.

Abstract: A method and apparatus to securely distribute embedded firmware to a module in an industrial control system is disclosed. A security certificate corresponding to the firmware is generated utilizing a proprietary algorithm. The certificate includes an identifier corresponding to the module on which the firmware is to be loaded and an identifier corresponding to a removable medium on which the firmware is distributed. The removable medium is inserted into the module in the industrial control system on which the firmware is to be loaded. The module reads the security certificate and verifies that the firmware is intended for the module and verifies that the security certificate includes the identifier for the removable medium which was inserted into the module. If the firmware is intended for the module and the security certificate includes the identifier for the removable medium, the module loads the firmware from the removable medium.

The chassis includes a front region having two opposing longitudinal edges, a back region having two opposing longitudinal edges, and a crotch region having two longitudinal edges. The crotch region is disposed between said front and back regions, and at least two side panels extend outwardly from the two opposing longitudinal edges of one or both of the front or back regions. The side panels may interconnect the front and the back regions to form a waist opening and a pair of leg openings. The article exhibits a pre-application side panel length, Li, and a post-application side panel length, Lf, such that Li is less than Lf. The article may also include a plurality of graphics.

Abstract: A method of forming a component includes defining an identification pattern, defining one or more scanning parameters and/or one or more heating parameters, depositing a sinterable material on a substrate and scanning a heat source of the deposited sinterable material to thereby selectively sinter the material to the substrate to produce a sintered layer having the identification pattern. The sintered layer includes first and second regions, and the method includes sintering the first region using one or more scanning parameters and/or one or more heating parameters having a first value, and sintering the second region using one or more scanning parameters and/or one or more heating parameters having a second value to thereby produce the identification pattern including a contrast between the first and second regions.

Abstract: In embodiments of document layer extraction for mobile devices, a cloud-based image service can receive a request from a mobile file browser for a multi-layered image, and the image service communicates an image preview and image layer previews of multiple layers of the multi-layered image to the mobile device for display. The image service generates a layer extraction that is a full-resolution image of each of the multiple layers of the multi-layered image. The image service can receive identifiers of layers that correspond to user selections of one or more image layer previews from the mobile device. The image service can then generate a component representation of the layer extractions that correspond to the identified layers of the multi-layered image, and then communicate the component representation of the identified layers to the mobile device.

Abstract: The present invention provides a pipe for transferring powder material from a reservoir to a container e.g. prior to hot isostatic pressing. The pipe comprises a continuous outer wall and a concentric continuous inner wall enclosed within and spaced from the outer wall. The spacing between the inner and outer walls defines a flow channel extending from an inlet to an outlet. The radial cross sectional area of the outlet is greater than the cross sectional area of the inlet.

The non-treatment part of the component is located substantially outside the treatment chamber and out of contact with the fluidized bed. The boundary between the treatment part and the non-treatment part of the component is defined by a boundary containment surface at a fixed location with respect to the component. The boundary containment surface may be a seal which seals between the component to be treated and an aperture in a side wall of the treatment chamber.
