Abstract: A caul body for forming a composite structure comprises a laminate having at least one carbon layer and at least one silicone layer. The at least one silicone layer defines an outer surface of the laminate. The laminate has a first region and a second region. A thickness of the at least one carbon layer in the first region is greater than a thickness of the at least one carbon layer in the second region. The first region has a hardness value greater than a hardness value of the second region.

Abstract: A bonded part includes a first surface facing toward a second surface, and a cured adhesive between the first and second surfaces defining a bond line. A surface structure on the first surface is within the bond line and has surface protrusions arranged in a pattern. Each surface protrusion protrudes outwardly from a first end at the first surface to a second end adjacent to the second surface. A thickness of the surface protrusions is substantially equal to the thickness of the bond line. The cured adhesive extends around the surface protrusions. The thickness of the bond line between the first and second surfaces is substantially constant along the bond line, and is greater than a thickness of the cured adhesive between the second ends of the protrusions and the second surface.

Abstract: A method of manufacturing a monolithic component having internal wall(s), including separately placing uncured composite material on a mold parts, placing the mold parts on a support plate with a portion of the uncured composite material extending between and in contact with the adjacent mold parts, interconnecting the adjacent mold parts through a connection allowing limited relative movement on the support plate along a direction corresponding to a thickness of the uncured composite material therebetween, biasing the adjacent mold part toward each other along the limited relative movement to provide a compressive force on the uncured composite material extending therebetween, and curing the composite material to obtain the monolithic component with each internal wall being formed between adjacent mold parts. The bias causes the adjacent mold parts to move toward each other as the thickness of uncured material extending therebetween reduces during curing. A tool assembly is also discussed.

Abstract: A method of manufacturing a door skin and a fuselage wall having a doorway and a member extending into the doorway for abutting the door includes placing a first sheet of uncured composite material on a mold plate to define the door and fuselage skin, disposing an insert over the first sheet overlapping a desired periphery of the door, placing a second sheet of uncured composite material on a peripheral portion of the insert and over the first sheet adjacent the peripheral portion of the insert to form the member, curing the sheets and bonding the sheets together adjacent the insert during the cure, removing the insert from between the sheets after cure, and separating the door skin from the wall skin after cure by moving a cutting tool through the first sheet and without penetrating the second sheet around the desired periphery of the door. An assembly for manufacturing the door skin and a fuselage wall is also discussed.

Abstract: A method of manufacturing a self-supporting, monolithic fuselage body, including engaging peripheral mandrel sections around at least one central mandrel section, placing uncured composite material on the mold surface, curing the composite material on the mold surface, and sliding the central mandrel section(s) out of engagement with the peripheral mandrel sections and disengaging the peripheral mandrel sections from the cured composite material without collapsing the mandrel sections. The peripheral mandrel sections each include a shape-retaining core of a thermally insulating material and an outer layer on an outer surface of the shape-retaining core. The outer layer has a coefficient of thermal expansion within the range of variation of that of the coefficient of thermal expansion of the composite material. A mandrel for layup and cure of a predetermined composite material in the manufacture of a monolithic fuselage is also discussed.

Abstract: Techniques for suggesting a tag for content may include the following: receiving, from a member of a social network, an entry in a display field along with an indication that the entry is for a post; after receiving the entry and the indication, identifying content by performing a search using at least some of the entry and information about the member of the social network; obtaining tags corresponding to the identified content; ranking the tags; outputting the ranked tags as suggestions to include with the display field; and augmenting the entry by adding a selected tag to the display field.

Abstract: Embodiments refer generally to systems and methods for manufacturing a cylindrical spar tube of the sort that might be used in a horizontal stabilizer for a helicopter. An exemplary method may comprise laying out onto a flat surface (and possibly stacking) plies of composite material, rolling the material onto a mandrel while applying pressure and curing the rolled material.

Abstract: The subject matter of this specification can be implemented in, among other things, a method for providing socially relevant content in a news domain. The methods includes a steop for receiving a request from a user for a news aggregator page related to a news story. The method also includes a step for retrieving social contents items related to the news story. The method also includes a step for providing the news aggregator page for display, wherein the news aggregator page includes multiple links to news content items related to the news story, and the retrieved social content items related to the news story.

Abstract: Effective aspects of stamping outbound e-mail are combined with a registration and entity identification system for e-mail senders. A mail sender participates by registering From: line and entity information with a trusted third-party repository known as a stamp authority. When the sender sends an e-mail message, the From: line is compared against the From: line information for the sender stored in the repository. If the result is a match, entity information is added and the e-mail is allowed to be sent. If there is not a match, then the e-mail is prevented from being stamped.

Abstract: A ground shoe assembly for a snowblower being of the type having an auger and mounted to a tractor, which the ground shoe assembly is pivotally mounted on the snowblower so as to pivot about an axis parallel to the axis of rotation of the auger.

Abstract: A curved blade mounted to bottom from both curved sides joining the blade rotation mechanism components assembling allows the height adjustment according to the desired rotational movement, and is assembled to the parts for transmitting motion fixed onto the snow blower. A sliding protective plate replacing the ground shoe, is mounted under the curved blade provided with an interchangeable cutting edge protecting the curved blade and the gravel inputs or all other materials during the snow blowing.
