A blade outer air seal for a gas turbine engine having a surface that is eccentric with respect to the engine rotation centerline, and a method for creating same, are disclosed. Also, a method for grinding a work piece having nominal curvature defined by a work piece curvature centerline is disclosed, comprising the steps of: a) determining a desired surface profile for the work piece; b) providing a rotating grinding surface having a grinding rotation centerline; c) offsetting the grinding rotation centerline from the work piece curvature centerline; and d) applying the rotating grinding surface to the work piece while rotating the rotating grinding surface about the grinding rotation centerline to create the desired surface profile.

Manhole inserts suitable for deployment in a manhole opening of a manhole structure may include a manhole insert bottom. A manhole insert sidewall may extend from the manhole insert bottom. A manhole insert flange may extend from the manhole insert sidewall. A manhole insert gasket may be on the manhole insert flange, The manhole insert gasket may include a solidified, hardened, and cured gasket material having a synthetic silicone elastomer. The manhole insert gasket may be configured to remain exposed on the manhole insert flange prior to deployment of the manhole insert in the manhole opening of the manhole structure.

A hybrid torque bar for a brake assembly may comprise a base portion, a pin extending from a first end of the base portion, and a rail extending between the first end of the base portion and a second end of the base portion opposite the first end. The base portion may be formed using a first manufacturing process. At least one of the pin or the rail may be formed using a second manufacturing process. The second manufacturing process may comprise an additive manufacturing technique.

There is disclosed a member for sealing, baffling and/or reinforcing components of an automotive vehicle. The assembly generally includes a carrier, an expandable material and at least one fastener.

A rigid electrical raft is provided to a gas turbine engine via a fusible mount arrangement. The rigid electrical raft may be a part of an electrical system of the gas turbine engine, for example a part of the electrical harness. The fusible mount is arranged to break when a predetermined load is applied. The rigid electrical raft may be attached to a fan case of the engine, and the predetermined load may be that which results from a fan blade being released from the hub. This ensures that the rigid electrical raft is protected from the load.

An implantable tissue marker incorporates a contrast agent sealed within a chamber in a container formed from a solid material. The contrast agent is selected to produce a change, such as an increase, in signal intensity under magnetic resonance imaging (MRI). An additional contrast agent may also be sealed within the chamber to provide visibility under another imaging modality, such as computed tomographic (CT) imaging or ultrasound imaging.

The disclosure relates to a method for producing a overlapping connection, in which at least two overlapping components are connected to one another via a folded flange, with a first edge of a first component being folded over a second edge of a second component to form the folded flange, along with a body component that includes such an overlapping connection for a vehicle and a stamping tool for such a body component. According to the disclosure at least one connection region is formed on the folded flange, in which the stamping tool stamps the first component through the second component at least one stamping point, with displaced material of the first component passing into the second component and producing a positive connection.

An additively manufactured component is provided. The additively manufactured component includes an additively manufactured first part defining a first trench, an additively manufactured second part defining a second trench and a fiber optic sensor. The additively manufactured first and second parts are additively manufactured together with the first and second trenches corresponding in position such that the additively manufactured first and second parts form an assembled part with a fiber channel cooperatively defined by the first and second trenches. The fiber optic sensor includes a first sensor part embedded in the fiber channel and a second sensor part operably coupled to the first sensor part and extendible at an exterior of the assembled part.

A method for surface treating a golf club head, includes: (a) forming a depression unit in the golf club head, the depression unit being indented inwardly from an outer surface of the golf club head, the outer surface being divided into a working area and a non-working area, the depression unit being formed in the working area; (b) filling the depression unit with a shielding material and covering the non-working area with a covering material; and (c) sandblasting the golf club head after step (b) and removing subsequently the shielding material from the depression unit and the covering material from the non-working area so as to form the working area into sandblasted and non-sandblasted regions that differ in gloss intensity.

Methods for separating cells from a sample (e.g., separating fetal red blood cells from maternal blood) include introducing a sample including cells into one or more microfluidic channels. In one embodiment, the device includes at least two processing steps. For example, a mixture of cells is introduced into a microfluidic channel that selectively allows the passage of a desired type of cell, and the population of cells enriched in the desired type is then introduced into a second microfluidic channel that allows the passage of the desired cell to produce a population of cells further enriched in the desired type. The selection of cells is based on a property of the cells in the mixture, for example, size, shape, deformability, surface characteristics (e.g., cell surface receptors or antigens and membrane permeability), or intracellular properties (e.g., expression of a particular enzyme).
