Abstract: A thread forming screw (10) having a minimum surface hardness of HRC 56. The screw (10) can form threads in a workpiece having a surface hardness which exceeds HRC 23. A method of surface hardening a screw (10) includes carbon enriching the screw (10) to at least a 0.48 carbon level, and then quenching the screw (10). Then, the screw (10) is tempered such that the surface hardness does not exceed the core hardness by more than 3 Rockwell C points, and both the surface and core are at a Rockwell C33-C39 hardness. Subsequently, the point (16) is induction hardened, and the screw is quenched again. The screw (10) is again tempered such that the lead threads (18) and the first 3-4 full threads (22, 24) are at a Rockwell C56 minimum hardness, preferably to a depth (26) of at least 0.008 inches, and the core of the fastener (10) is at Rockwell C33-C39 hardness. Finally, a finish is applied.

Abstract: Fine particulate polymer drag reducing agent (DRA) in bi-modal or multi-modal particle size distributions may be produced simply and efficiently without cryogenic temperatures. The grinding or pulverizing of polymer, such as poly(alpha-olefin) suitable for reducing drag in flowing hydrocarbons may be achieved by the use of at least one liquid grinding aid and at least two grinding processors in series. The impellers of the grinders are of different openness so that granulated polymer fed to the first processor having a relatively more open impeller is ground to an intermediate size which is fed to the second processor having a relatively more closed impeller which grinds the polymer to a second, smaller size. A non-limiting example of a suitable liquid grinding aid includes a blend of propylene glycol, water and hexanol. Particulate DRA may be produced at a size of about 300 microns or less in only two passes.

Title: Centrifugal pellet dryer screen with integral embossed deflector strips
Inventor: BRYAN DAVID
IPC: F26B5/08
Filed: 2008-05-22
Abstract: An embossed screen having raised deflector elements on the internal surfa ce is provided for a centrifugal pellet dryer. The deflector screen is forme d as an integral structure, eliminating the need for separate deflector comp onents secured by fastening elements along with the associated risks such as loosening or separation of the strip and contaminate build-up between the s trip and the screen. The embossed deflector screen effectively deflects the pellets back toward the rotor where the pellets are reengaged with rotor ene rgy, resulting in increased dryer efficiency and flow rate. The embossed def lector screen also enhances the overall structural strength of the screen, r educes manufacturing costs and prevents pellet entrapment that can lead to c ontamination in future runs.

The toner includes a colorant for printing an image on a surface of a document, a fluorescent pigment that under normal lighting is masked by the colorant but creates a visible image on the first surface of the a substrate when irradiated by black or ultra-violet light, and a dye for forming a latent version of the image underneath a surface of a substrate. An image formed using the toner of the invention is readily verified by comparing the colorant-formed image and the dye-formed image. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.
