摘要:
A high aspect ratio, low solidity fan blade of an axial flow air cycle machine has a local tip center of gravity axis that has been shifted ahead of an elastic axis. The center of gravity axis can be shifted by clipping the tip of the blade at the trailing edge, by undercutting a rear portion of the pressure surface, or by sweeping forward leading and trailing edges of the blade by about five degrees (without clipping or undercutting the blade).

This invention discloses a film and a method for forming a film that can be printed directly using electrostatic priming processes, eliminating the need for transfer of electrostatic images from an electrostatic paper to a polymeric film. The film is durable and conformable to a variety of surfaces and optionally has a field of pressure sensitive adhesive thereon for adhering to such variety of surfaces.

Electrostatically charged graphic sheets are additionally provided with a preapplied activatable adhesive. Such sheets may be oriented on a display substrate using the electrostatically induced adhesion, and more securely fastened to the display substrate using the activatable adhesive.
摘要:
A method and apparatus to improve toner drying on electrostatic printing media is disclosed. A drying apparatus placed between two print stations in a single pass electrostatic printer provides air from two different drying assemblies, one adjacent to one print station and a second adjacent to a second print station.
摘要:
An adapter for blow molding machines mounted upon the piston of an expansible chamber motor for advancing and retracting the blow pin, the blow pin being mounted upon the adapter, and the adapter includes adjusting means for laterally adjusting the blow pin relative to the expansible chamber piston so as to accurately position the blow pin end within the mold to permit the blow pin end to be accurately located with respect to the associated shear steels and air seal.
摘要:
The invention relates to a method of manufacturing a replication master tooling article suitable for manufacturing replicated articles by machining a substrate surface with laser energy to produce a plurality of geometric structures in the substrate, the geometric structures having side surfaces extending from the surface of the substrate into the substrate.
摘要:
An adjustable shear plate for blow molding equipment wherein the shear steels or plates for cutting off the neck of the blown product, usually a bottle, may be adjustable with respect to each other to compensate for wear and achieve a sharp definitive severance. The adjustable components include a shear plate holder movably mounted upon a top plate or block support, and a slide selectively positionable upon the top plate support is operated by a rotatable cam to position the shear plate holder as desired. Rotation of the cam displaces the slide to engage and adjustably position the shear plate holder and shear plates mounted thereon.
