Abstract: Reprocessing of a replaceable supply component may include receiving from an encoding device and using an interface communicatively coupled to the encoding device, a request blob to reprocess a replaceable supply component. The method may include in response to cryptographically verifying the request blob, extracting from the request blob, a supply identifier and raw supply data. The method further includes using the supply identifier and raw supply data, generating a reprocess structure to append or amend original manufacturing data for the replaceable supply component, and providing a response blob to the encoding device, to designate the replaceable supply component as a reprocessed supply component.

Abstract: An example method comprising requesting authorization to reprocess a replaceable supply component using an interface and original manufacturing data stored in memory of the replaceable supply component. The method further comprises, in response to the request, receiving configuration data using the interface, and appending the original manufacturing data with the configuration data to designate the replaceable supply component as reprocessed, wherein the configuration data is to cause reconfiguration of an end-user device in response to attachment of the replaceable supply component to the end-user device and execution by the end-user device.

Abstract: Generating a request for reprocessing of a replaceable supply component may include sending to a non-volatile memory of a replaceable supply component, a request for information about the replaceable supply component. The method may include receiving from the replaceable supply component, the supply component information, wherein the supply component information includes data to be decrypted by an exchange service. The method may further include generating a request blob including the supply component information, and cryptographically signing the request blob for sending to the exchange service for reprocessing of the replaceable supply component.

Abstract: A turbomachine blade includes a root intended to be mounted in a recessed pocket of a turbomachine rotor disc, the root having two side faces extending radially and longitudinally, each of the side faces including at least one seating intended to be inserted against a side wall of the recessed pocket, along an axis of longitudinal direction and to be in contact with the side walls of the recessed pocket, a radially inner face intended to face the bottom of the recessed pocket when the root is mounted in the recessed pocket, the radially inner face connecting the two side faces, the radially inner face including at least one curved concave surface and two curved convex surfaces, the curved concave surface extending from one end of each of the two curved convex surfaces.

Abstract: Dissymmetric particles also called Janus particles of micron or submicron size and methods of synthesis of Janus particles by bipolar electrochemistry, based on substrates of isotropic or anisotropic shape. The particles include an electrically conductive substrate having at least a chemically and/or physically modified part by deposit of a layer of electrochemically depositable material, and a non-modified part. The particles are of isotropic shape, and the layer of electrochemically depositable material has a specific shape delimited by a precise contour.

Abstract: A method of hydroprocessing a heavy hydrocarbon feedstock using a hydroprocessing catalyst having specific properties making it effective in the hydroconversion of at least a portion of the heavy hydrocarbon feedstock to lighter hydrocarbons. The hydroprocessing catalyst comprises a Group VIB metal component (e.g., Cr, Mo, and W), a Group VIII metal component (e.g., Ni and Co) and, optionally, a potassium metal component that are supported on a support material comprising alumina. The alumina has novel physical properties that, in combination with the catalytic components, provide for the hydroprocessing catalyst. The hydroprocessing catalyst is particularly effective in the conversion of the heavy hydrocarbon feedstock. The alumina is characterized as having a high pore volume and a high surface area with a large proportion of the pore volume being present in the pores within a narrow pore diameter distribution about a narrowly defined range of median pore diameters.

Abstract: A bearing assembly includes an outer ring having an inner circumferential surface and a generally annular recess extending radially outwardly from the inner surface. An inner ring is disposed at least partially within the outer ring so as to be rotatable about a central axis, the inner ring having an outer circumferential surface spaced radially inwardly from the outer ring inner surface and at least one integral shoulder extending radially outwardly from the outer surface so as to be disposed at least partially within the outer ring recess. The shoulder is engageable with the outer ring when the inner ring is subjected to an axial force so as to substantially prevent axial displacement of the inner ring relative to the outer ring. Preferably, a plurality of rolling elements are disposed between and rotatably couple the inner and outer rings.

Abstract: Disclosed is a composition useful in the saturation of aromatics contained in a hydrocarbon feedstock. The composition includes a support composition having a high macroporosity of greater than 51 percent. The support composition comprises an amorphous silica-alumina having unique properties.
