Title: High temperature countercurrent solvent extraction of capsicum solids
Inventor: TODD GEORGE N
IPC: A23L27/10
Filed: 1997-12-12
Abstract: Principal components of paprika red pepper, pungent chili, or other spice plants, e.g., of the genus Capsicum containing carotenoid pigments, are simultaneously extracted and concentrated with an edible solvent in a series of mixing and high temperature and pressure mechanical pressing steps using edible solvent and a countercurrent extraction procedure. The extract containing the carotenoid pigments may be hydrated and then centrifuged to remove fine particulate solids and gums. A solution having several times the concentraton of the carotenoid pigments and other flavor and aroma components of the starting raw material is obtained. The residual press solids may be cooled and hydrated following the last pressing operation.
Patent CA-2273566-A1 (CA)
Inventor: HESS DAVID W
IPC: B31F1/28
Filed: 1999-05-31
Abstract: A method and apparatus for producing a single face corrugated web in which a steam cloud is injected between the corrugated medium web and the liner web directly at the line along which the webs converge. This type of steam injection allows faster corrugator speeds without sacrificing bonding quality. An adhesive slurry of water and starch granules is applied to the flute tips to form glue lines on the corrugated web prior to the convergence of the webs. The injected steam cloud directed at the web convergence line adds heat without promoting premature dehydration to facilitate proper conditions for effective cooking of the adhesive slurry to thoroughly gelatinize the adhesive. In some applications, dry steam is preferred because dry steam does not significantly interfere with subsequent dehydration of the adhesive gel during the formation of the initial green bond.

Title: Resistance weld control system with line impedance compensation
Inventor: BAILEY JONATHAN H
IPC: B23K11/25
Filed: 1999-01-25
Abstract: A phase controlled weld controller system uses an internal model of weld line and load impedance and of open circuit weld input voltage to develop a nominal firing angle sequence to maintain a desired weld current sequence. The weld controller computes a nominal firing angle sequence based on estimated models of line impedance, open circuit line voltage, and an estimated relation between the load current and conduction angle and the mathematical relation between firing angle, conduction angle and load circuit power that will achieve a desired weld sequence if the models are accurate. The weld controller subsequently uses measured values received in real time while the weld sequence is being executed to modify the nominal firing angle to better achieve the desired objective. This approach allows the weld controller to quickly achieve the desired weld sequence with the actual load, while permitting low feedback gains, resulting in a system that is quick and accurate in response without being overly sensitive.

The chronological list pointer field of a transaction entry points to the next oldest transaction entry. The indexed list includes a number of indexed list entry pointers. Each indexed list entry pointer corresponds to an index and points to a transaction entry with the same index. Th indexed list pointer field of a transaction entry points to another transaction entry with the same index. Adding a transaction entry to the transaction log or deleting a transaction entry from the transaction log includes updating the chronological list pointers and the indexed list pointers.

Title: Lift mechanism for infant care apparatus canopy
Inventor: JONES THOMAS C
IPC: A61G11/00
Filed: 2000-03-13
Abstract: An infant care apparatus that has a canopy that can be moved vertically with respect to an infant pedestal on which the infant is positioned. In the preferred embodiment, the canopy contain a radiant heater that can be moved from a lower position enclosing the infant in an infant compartment to an upper position where the infant compartment is open. The canopy is affixed to a movable frame member that is, in turn, movably mounted on a stationary frame member. A constant force spring or springs are used to interconnect between the stationary frame member and the movable frame member and the springs are designed so as to achieve a counterbalancing of the canopy and associated components such that the weight of such canopy and components is neutralized. Thus, a standard, inexpensive motor c:an be used to raise and lower the canopy without complex synchronization between two motors and yet the unit moves smoothly and without misalignment. In addition, two sets of stationary and movable frame members can be used and position the motor and its lifting mechanism in only one of the sets of frame members without creating a misalignment of the frame members as the canopy is raised and lowered.

Title: Methods for manufacture of fat-free cream cheese
Inventor: HAYASHI DAVID
IPC: A23C19/028
Filed: 2000-03-21
Abstract: The present invention provides a process for making a fat-free cream cheese-like fermentation product having similar textural and organoleptic properties similar to that of a higher fat containing cream cheese. In the process, a skim milk composition having a high solids content and a low fat content is cultured with a ropy culture until the pH reaches a value of about 5.2 to about 4.9. The cultured mixture is blended with at least one bulking agent and at least one emulsifier to form a blend, which is heated to a temperature of about 60°C to about 65°C. After adding a vegetable gum, the heating is continued until a temperature of about 80°C to about 90°C is reached. The heated mixture is blended and homogenized to form the fat-free cream cheese-like fermentation product. The present composition and process does not require the addition of relatively costly cottage cheese solids or curds as required by conventional cream cheese processes. The fat-free cream cheese-like fermentation product has comparable firmness, consistency, and flavor of a conventional higher-fat cream cheese.

Title: An improved method and apparatus for per pixel mip mapping and trilinear filtering
Inventor: MUNSHI AAFTAB
IPC: G06T17/00
Filed: 1999-06-24
Abstract: The number of computations performed in rendering graphics is reduced by computing certain terms only at the beginning of each scanline. A scanline gradient is calculated once at the beginning of each scanline for each of two texture values with respect of the x-coordinate of the scanline. Following the scanline gradient calculations at the beginning of each scanline, a pixel gradient is calculated for each pixel of the scanline with respect to the ycoordinate of the scanline. The sum of the squares of the scanline gradients and the pixel gradients are compared, and the larger of the two quantities is selected to be a maximum Rho constant term for the corresponding pixel, wherein the maximum Rho constant is used to select a texture map for rendering the corresponding pixel. Furthermore, at the beginning of each scanline, a pixel gradient may be calculated for each of two texture values for a first pixel of the scanline with respect to the y-coordinate of the scanline. Derivatives are calculated for the pixel gradients, wherein pixel gradients are found using the derivatives, thereby eliminating the calculation of pixel gradients for each pixel.
