Title: Method for hydrotreating and upgrading heavy crude oil during production
Inventor: DAVIS ROBERT MICHAEL
IPC: E21B43/16
Filed: 1996-06-20
Abstract: Heavy crude oil containing at least 1% by weight water is hydrotreated and upgraded while being produced downhole in a production well. During production the heavy crude oil containing water is subjected to sonic energy at a low frequency of 400 Hz to 10 kHz downhole in the presence of a metal hydrogenation catalyst that causes the water in the crude oil to react and form hydrogen which then hydrotreats and upgrades the heavy crude oil during production. In another embodiment, if the heavy crude oil does not contain water, the hydrogen may be formed in-situ by contacting the heavy crude oil downhole with a chemical compound comprising ammonia, hydrazine and formic acid that in the presence of a metal hydrogenation catalyst and sonic energy causes the chemical compound to react and form hydrogen which then hydrotreats the heavy crude oil during production.  Suitable catalysts include nickel on zinc dust, platinum on carbon and palladium on carbon, preferably nickel on zinc dust.  The hydrotreated and upgraded heavy crude oil has improved properties making it easier to refine and transport by pipeline.  The upgrading includes reducing the amount of asphaltenes and resins in the heavy crude oil and increasing the amount of aromatics and saturates.

Title: Method and apparatus for separating meat from bones
Inventor: GOLDSTON THOMAS C
IPC: A22C17/04
Filed: 1997-04-04
Abstract: A press for separating meat from bones includes an annular pressure chamber defined by an inner slotted separation chamber surrounded by an outer slotted separation chamber for reducing pressure within the chamber by increasing the total open area in the slotted chambers through which the meat can flow, to improve upon the texture of the meat recovered, to reduce its calcium content, and to avoid the total destruction of the bone. Pressure reduction is effected by reducing the volume of the product being depressed in the annular chamber, the elongated slots of the separation chambers present shearing edges for shearing away the meat from the bone as the separation chambers are counter-rotated. A back pressure control valve automatically opens in response to annular chamber pressure acting as a flow restrictor for controlling the pressure. Knife blades for the slotted separation chambers remove connective tissues from the slots to prevent clogging and to further reduce the calcium content of the recovered coarse meat.

Filed: 1997-06-02
Abstract: A improved fault model for analog and mixed signal circuits is presented. The fault modelling is based on the estimation of perturbation due to physical failure and structural fault. The proposed fault model is based on the estimation of statistical distributions of faulty and fault-free circuits responses. The proposed functional fault modelling is technology independent. Also, the LIMFault simulation which uses the sensitivity for perturbation estimation for fault activation and propagation is presented. The first order estimation is used in order to speed-up the fault simulation and allow to estimate the response and variation of faulty and fault-free circuits without using circuit simulator. The perturbation fault model can be used with other techniques that compute the distribution. The experimental results for analog and mixed signal circuits show the effectiveness of the proposed fault simulation in reducing the fault simulation time and reducing the total number of faults without affecting the fault coverage.
