Title: Stainless steel surface claddings of continuous caster rolls
Inventor: HORN BRUCE D
IPC: B23K37/08
Filed: 1996-11-06
Abstract: A heat-treated cladding (44) on the working surfaces of continuous caster rolls (40) reduces sensitization zones. The thermal treatment applied conditions the working surface (44) of the roll substantially uniformly at all positions around the perimeter of the roll (40), thereby disolving carbide formations into an austenite solution and removing carbide formations and chromium depletion sites or sensitized zones associated with the reheat regions occurring during the welding process. The heat treatment process is accomplished without thermally affecting or altering the properties and dimensions of the base roll material, either at a substantial depth beneath the body working surface or on or beneath the roll journal surfaces.

Title: Multi-functional cleaning machine
Inventor: ROBINSON ROBERT S
IPC: B08B9/02
Filed: 1998-07-02
Abstract: A particular multi-functional cleaning machine, in accordance with the principles of the invention, includes a water-tank and a liquid delivery line extending from the water tank to a high-pressure spray gun. The liquid delivery line has an inner end, a pump, and an outer end, with the inner end connected to the water tank, and the outer end connected to the high-pressure spray gun. The machine also has a cleaning-liquid draw line which is connected to the liquid delivery line using a cleaning-liquid injector.

IPC: H04L9/08
Filed: 1998-12-22
Abstract: Disclosed is a method for safe distribution of encryption keys including a known public and secret private keys in establishing a secure link between computer users residing at separate locations whom have no previous secure communications. The secure communication link occasionally and anonymously interrogates the key distribution center for the certificate pertaining to the computer users in ensuring the validity and integrity of the information stored in the center which is not tampered by any unauthorized persons. The interactively interrogating of the key distribution center is conducted via a trusted and verified certificate decision making process which encompasses the acknowledging to user who receives a valid certificate, accepting an encrypted message, key distributed center's answer to the correct up-to-date certificate, decrypting the key distributed answer via the public key, and matching the answer's identification. As the result of the multi-steps process exchanged among users via key distributed center and other secure devices, the secure link can be established between the computer users in allowing data to be transferred from one computer location to another computer location in providing a very high reliability and confidentiality of users' data connectivity.

Title: Digital modulation system using modified orthogonal codes to reduce autocorrelation
Inventor: VAN NEE RICHARD D J
IPC: H03K7/10
Filed: 1999-02-15
Abstract: A digital modulation system provides enhanced multipath performance by using modified orthogonal codes with reduced autocorrelation sidelobes while maintaining the cross-correlation properties of the modified codes. For example, the modified orthogonal codes can reduce the autocorrelation level so as not to exceed one-half the length of the modified orthogonal code. In certain embodiments, an M-ary orthogonal keying (MOK) system is used which modifies orthogonal Walsh codes using a complementary code to improve the auto-correlation properties of the Walsh codes, thereby enhancing the multipath performance of the MOK system while maintaining the orthogonality and low cross-correlation characteristics of the Walsh codes.

Title: Estimating the difference in picture quality between two versions of a video signal
Inventor: BOCK ALOIS MARTIN
IPC: H04N7/30
Filed: 1999-02-24
Abstract: The invention relates to estimating the difference in picture quality between two versions of a video signal, one of which has been subject to distortion and the other of which has not been subject to the distortion. The invention has application to estimating the picture quality of a signal subjected to digital compression in comparison to the picture quality of the signal before compression. The estimate of picture quality is obtained by first deriving a difference signal representing the difference between the distorted and undistorted versions of the video signal. A masking signal is obtained by filtering the undistorted version of the video signal and is used to mask the difference signal thereby to derive an output measure of the said difference in picture quality. The masking signal is obtained by filtering the undistorted version of the video signal through a channel including a high-pass edge detection filter.  Preferably, a second measure of the difference in picture quality is obtained by applying both the distorted and undistorted versions of the video signal to a circuit that detects block distortion across block boundaries. The output from the block distortion circuit is also masked by the masking signal.

Title: Tracheal tube
Inventor: GOEBEL FRED G
IPC: A61F2/958
Filed: 1997-09-08
Abstract: The invention concerns a tracheal tube (1) that closes the trachea liquid-tight, comprising a cuff (5) blocking the trachea below the glottis and through which a respiration cannula (1) is passed. A tampon vesicle (7) made out of flexible material which expands as fluid flows through is cranially placed above the cuff. When filled, said vesicle differs in shape from that of the cuff. This tracheal tube must be improved so that a patient can be intubated for a long period of time with the minimum of suffering and with a reduced risk of infection. According to the invention, this is accomplished by the fact that the tampon vesicle (7) once filled rests directly on the cuff (5), the tampon vesicle is made out of a foil-like material and its filled size is designed to fill the subglottic region.
