摘要:
A web for forming sealed air filled pouches includes a plurality of fold seals that seal first and second elongated layers together along a fold area defining first and second chambers. The fold seals create a cushioned area along a fold area when the first chamber is folded over the second chamber. Also disclosed is a device for separating air filled pouches. The device includes a first stage including a first belt operating at a first speed and a second stage including a second belt operating at a second speed. The web passes through the first stage before passing through the second stage. A pouch is separated from the web at the lines of perforations when a relative speed of the first belt is slower than a speed of the second belt by a predetermined threshold.

A skin-stiffener transition assembly (1) with a skin (4) and two L-shaped fiber-reinforced fabric preforms (2, 3) for a flange and a composite gusset filler (5) integrated between said skin (4) and said two L-shaped fiber-reinforced fabric preforms (2, 3). The skin (4) comprises two separate skin layers (7, 8) and the flange comprises a flange layer (6), each of said skin layers (7, 8) and said flange layer (6) being provided with cut outs (9, 10) along one side. Said skin layers (7, 8) and the flange layer (6) are attached to the composite gusset filler (5) with at least one of its cut-outs (9, 10) to one side of the essentially polygonal cross section of the composite gusset filler (5) and with at least one of its adjacent cut-outs (9, 10) to another side of the essentially polygonal cross section of the composite gusset filler (5). The present invention relates as well to a method of manufacture of said skin-stiffener transition assembly (1) and to applications of said skin-stiffener transition assembly (1).

Included herein are constructional techniques as well as finished goods produced thereby. The techniques described are especially useful in producing curved structures in topographical fashion with cutouts from sheets of thermoplastic composites material.
摘要:
An assembly including a polymeric member and a unitary metal casting wherein the metal casting relatively moveably captures the polymeric member on the metal casting. The assembly can be adapted for use as a crank arm in a transmission shift mechanism. In some embodiments of the assembly, the polymeric member includes an opening defining a rotational axis of said polymeric member. The metal casting extends into the opening and includes at least one enlarged diameter portion with the polymeric member being rotationally disposed on the metal casting and axially captured on the metal casting by the at least one enlarged diameter portion of the metal casting. A method of manufacture is also disclosed.

A vacuum insulation panel (VIP) in an example comprises first and second walls and a plurality of tensile elements. The first and second walls are structurally coupled to allow formation of a vacuum cavity between the first and second walls. The plurality of tensile elements structurally supports the first and second walls against external pressure contemporaneous with tension on the plurality of tensile elements. The plurality of tensile elements is located in the vacuum cavity between the first and second walls.
摘要:
The object is to provide a resin film capable of retaining a predetermined bent shape, so that the resin film may be employed in a handy and effective manner in the image forming apparatus as such a component as a guide, a cover, etc. The resin film formed product includes a plurality of resin films bonded to each other. Each resin film is bonded with having a bent portion.

The laminated structure includes a lightweight and shape-retaining foamed resin base member, an outer circumference frame integrally laminated on the reverse side of the foamed resin base member along the outer circumference of an article, and bridging ribs connecting between respective points on the outer circumference frame. Accordingly, the present invention provides a lightweight laminated structure with low cost by reducing the amount of the resin used, since the molded synthetic resin outer circumference frame and bridging ribs have small projection areas.
摘要:
Methods and apparatus are provided for a composite structural material. A non-solid composite section that is filled with a structural foam that reduces the weight of the composite structural material. A solid composite section that is coupled to the non-solid composite section. The solid composite section is an area for structural attachment for the composite structural material. A region adjoining the non-solid composite section to the composite section is radiused to reduce stress when the structural foam is bonded to the region. The radius in the region prevents delamination and cracking of the structural foam when a load is placed on the composite structural material.
摘要:
A paint mask particularly adapted for masking corner areas of a demarcation zone to facilitate painting of an area of a workpiece disposed on the other side of the demarcation zone is formed of a thin, flexible sheet having opposite faces. The paint mask includes a first leg and a second leg that are generally rectangular in shape, and the legs intersect to form a right angle adapted for masking a corner and adjacent area. The bottom side of the paint mask which contacts the surface to be masked includes an adhesive for adhering the mask to the workpiece. The top side has release means for releasing stacked paint masks from each other.
