Title: A surface nitriding method of an aluminum material, and an agent for nitriding
Inventor: KATOH HARUZO
IPC: C23C8/24
Filed: 1996-10-02
Abstract: This invention aims to provide a nitriding method of forming a relatively thick nitride layer on the surface of an aluminum material containing silicon, and an auxiliary agent for nitriding.        By using a nitriding auxiliary agent mainly comprising aluminum containing a metal such as lithium or boron, which has a high bonding strength with oxygen, coexists with silicon to form substantially no silicide, or a nitriding auxiliary agent mainly comprising an Al-Mg-Cu alloy or an Mg-Zn-Cu alloy, heat treatment is applied by nitrogen gas with the aluminum material to be nitrided contacted with the nitriding auxiliary agent.        Hence, a thick nitride layer can be easily formed even on the surface of an aluminum material containing silicon, and this is most suitable to surface nitride aluminum-silicon alloys, which possess superior castability.

Title: An impulse radar with swept range gate
Inventor: MCEWAN THOMAS E
IPC: G01S13/00
Filed: 1995-12-19
Abstract: A radar range finder and hidden object locator is based on ultra-wide band radar with a high resolution swept range gate. The device generates an equivalent time amplitude scan with a typical range of 4 inches to 20 feet, and an analog range resolution as limited by a jitter of on the order of 0.01 inches. A differential sampling receiver is employed to effectively eliminate ringing and other aberrations induced in the receiver by the near proximity of the transmit antenna (10), so a background subtraction is not needed, simplifying the circuitry while improving performance. Techniques are used to reduce clutter in the receive signal, such as decoupling the receive (24) and transmit cavities (22) by placing a space between them, using conductive or radiative damping elements on the cavities, and using terminating plates on the sides of the openings. The antennas can be arranged in a side-by-side parallel spaced apart configuration or in a coplanar opposed configuration which significantly reduces main bang coupling.

IPC: G06F21/00
Filed: 1996-05-28
Abstract: Ce système de protection conçu pour un logiciel de PC mémorisé dans des CD-ROM, empêche la copie illégale pour une augmentation négligeable du coût de l'application protégée. Le même CD-ROM qui contient le logiciel d'application sert de "code de protection". Le disque CD-ROM est soumis à un traitement spécial pendant sa phase de fabrication, ce qui permet d'obtenir l'anneau de contrôle. Ce système utilise un procédé spécial afin de vérifier l'authenticité de l'anneau de contrôle. L'existence de cet anneau, ainsi que la mise en application du processus de vérification d'authenticité, rendent impossible la copie du disque CD-ROM, même avec l'équipement d'enregistrement le plus évolué. Ce système présente de nombreux avantages par rapport à d'autres procédés de protection: une protection excellente, la transparence pour l'utilisateur final et un coût minimum, étant donné que le "code de protection" est le même disque CD-ROM contenant l'application. On peut utiliser ce système afin de protéger tout logiciel d'application pour des compatibles PC, mémorisé dans un CD-ROM et exécuté dans des environnements DOS ou Windows.

Title: Forward error correction assisted receiver optimization
Inventor: ROBERTS KIM BYRON
IPC: H04L25/06
Filed: 1997-11-19
Abstract: A method for recovering an outgoing data signal from an incoming signal received over a transmission network is disclosed. The method provides for preparing a bit error rate (BER) map for a data regenerator, determining, on the BER map, an optimal operation point for a provisioned BERprov value, and monitoring the data regenerator to function in the optimal operation point for providing a regenerated data signal. In addition, the errors in the regenerated data signal may be further corrected using current forward error correction circuitry. To prepare a BER map, the data regenerator operates in an error mapping mode, wherein the incoming signal is decoded using a slicing level Vi and a phase shifted clock signal CLj. Each value BERi,j is measured over a preset period of time Tprov for a pair Vi,~j and stored in a memory. The BER maps may be prepared once a day or at any other suitable interval. In the optimization mode, the operation point for the regenerator is calculated for a BER contour corresponding to the provisioned BERprov, for detemining the coordinates Vopt and ~opt. In the data regeneration mode, the regenerated data signal is obtained using Vopt and ~opt.

Title: Natural draft automatic feed pellet stove
Inventor: JARVI MICHAEL A
IPC: F24B1/02
Filed: 1998-01-13
Abstract: A natural draft, gravity feed pellet stove.  The body of the stove is  formed by a vertical section of large diameter pipe, with an air intake pipe extending from the back of the stove to below a combustion grate.   Pellet fuel is discharged onto the grate through a slot at the bottom of a hopper, and the grate is sloped so that the pellets roll away from the slot and over the grate as they are  combusted.    The  combustion  gasses  flow  into  two exhaust pipes,  each having a diameter similar to that of the intake pipe so as to establish a 2:1 exhaust/intake flow ratio.   Cross-drilled reburner tubes are installed across the intake ends of the exhaust pipes to provide additional air for complete combustion.  The bottom plates of the storage hopper are free from attachment along their lower  edges,  so  that  these  expand  and  contract  on  a continuous basis with changes in the temperature of the stove; this causes cyclical distortion of the plates which shifts the fuel downwardly towards the discharge opening.
