An apparatus for assembling a composite arrangement including a plurality of functional elements each having an aperture for a shaft, in a predetermined angular position on the shaft, may include a plurality of retaining devices each intended for accommodating a functional element. The retaining devices may be arranged vertically one above another such that the apertures of the functional elements may lie on a vertical line. The apparatus may also include a vertically movable guide slide for the shaft so that a joining of the shaft with the functional elements may take place in a vertical direction. The apparatus may also include a heating device by which at least two functional elements may be heated simultaneously. The apparatus may further include a gripping device by which at least two functional elements which are to be joined may be removed together from the heating device and introduced into the retaining devices.

A coolable wall element for a gas turbine, having a base body with a first surface subjectable to a hot gas, second surface arranged opposite of the first surface, and first seat for housing edges of an impingement plate. The wall element has an impingement plate partly inserted into the first seat located at a distance and adjacent to the second surface. A coolable wall element with extended life time is provided with the impingement plate which is removably attached to the base body having a snap-in connection with a bendable retention tab extending from the rest of the impingement plate to a free end of the retention tab, wherein the base body has a second seat for the free end of said tab, the second seat blocks the moving of the impingement plate relative to the main body when the bendable retention tab is released.

A body support structure includes a frame and a membrane attached to the frame. The membrane includes elastomeric filaments. The membrane has a first region with a first stiffness and a second region with a second stiffness. The second stiffness is greater than the first stiffness. The membrane may form a part of a seat or a backrest.

A method for manufacturing a prosthetic hip acetabulum includes the following steps. First, one provides an insertion cup (1) having an inner concave receiving surface (3) having an opening surface (5) contained in an opening plane (P), and having an outer annular receiving structure (6). Next, one provides an installation and positioning insert (7) having a peripheral annular attachment structure (10) shaped to engage with the receiving surface (9) of the structure (6), fitting around that structure. Next, one heats the insert (7) in order to increase its size. Next, one fits the attachment structure (10) around the receiving surface (9) of the receiving structure (6). Finally, one cools the insert (7) to room temperature to reduce its size and achieve radial tightening of the attachment structure (10) on the outer annular receiving structure (6).

Fabrics that have been treated to create superhydrophobic, oleophobic and/or ice-phobic performance are manufactured or assembled in specific conforming shapes so they can be positioned on or pulled over and around certain objects for the purpose of making those objects superhydrophobic, oleophobic and/or ice-phobic so they are self-cleaning, water proof, ice-resistant, oil-resistant, corrosion barriers, etc.

A system and method determine a size and a shape for identical geodesic modules that are used to form a structure. The system and method may include analyzing input data regarding a size and a shape of the structure to be formed, and determining the size and the shape for each of the identical geodesic modules based on the size and the shape of the structure to be formed. The structure may include a framework including the identical geodesic modules. Each of the geodesic modules has a size and a shape that are the same as all of the other of the geodesic modules. A forming system and method position a framework and a covering skin of the structure in relation to a mandrel, and drill and rivet the framework to the covering skin with a plurality of operating heads.

A body support structure including a pair of laterally spaced apart supporting arms defining a gap therebetween, wherein each of the supporting arms includes an upper support having an upwardly extending upright and a forwardly extending seat support defining a seat part, and a lower support having an upwardly extending upright spaced apart from the upright of the upper support in a vertical plane. The uprights of the upper and lower supports define a backrest part. A pair of armrests each includes an upwardly extending portion connected to a respective one of the forwardly extending seat supports and a forwardly extending portion pivotally connected to the backrest part. A cross brace extends between and is coupled to the supporting arms proximate the pivotal connection. A flexible membrane extends between and is coupled to the supporting arms.

A clamping apparatus includes a clamping frame, a first guide, a clamp, a linear driver, and a pressure sensor. The first guide is disposed on the clamping frame. The clamp is slideably engaged with the first guide, the clamp being configured to linearly move along the first guide to adjust a distance between the clamp and the clamping frame. The linear driver is connected to the clamp, the linear driver being configured to cause, at least in part, linear motion of the clamp. The pressure sensor is configured to sense pressure applied to an object clamped between the clamp and the clamping frame.

In a shadow mask tensioning method and apparatus, a shadow mask supported by a support frame is positioned between a shadow mask frame and a set of actuators with a portion of the shadow mask extending across a gap between the support frame and the shadow mask frame. Under the control of a programmed controller, the set of actuators is caused to simultaneously displace numerous, spaced locations of the portion of the shadow mask into the gap to align alignment apertures of the shadow mask to predetermined positons in fields of view of cameras positioned to observe the alignment apertures. The shadow mask is then affixed to the shadow mask frame.
