Abstract: The present invention relates to a butter-containing spread, and a process for the production of the said spread. 
     The present invention provides an edible emulsion comprising 30-70%wt of an aqueous phase CHARACTERISED IN THAT it comprises both wet-concentrated and dry butterfat in a weight ratio of 1:10 to 10:1. It is believed that one advantage of using both wet and dry butterfat components stems from the difference in the organoleptic properties of these two components. The term wet-concentrated butterfat is intended to embrace within its scope both concentrated cream, having a fat content in excess of 40%wt and butter. Dry-butterfat is intended to embrace butter-fats which have been rendered anhydrous at some time during the concentration process. The dry butterfat component contributes a different set of flavour components to the product. It is believed that rendering the butterfat anhydrous causes the formation of flavour components which are not present in fresh dairy butter or cream.

Abstract: The present invention relates to an apparatus for effectively reducing vibrations of a vehicle engine and the vehicle body due to irregular combustion of the engine. In the inventive vibration suppressing apparatus, a generator (4) is provided which has a voltage regulator (9) to control a field winding (8) current so as to output a constant voltage to a battery (1). When irregular combustion of the engine is detected on the basis of a change in the engine speed, a voltage higher than the output voltage of the generator (4) is applied across the field winding (8) to increase the load torque on the generator (4). A change in the load torque of the generator (4) induces vibrations on the generator body due to reaction. When the generator vibrations and vibrations due to irregular combustion are in inverse phase relationship to each other, they are cancelled by each other to suppress those vibrations.

Abstract: A solid state microwave generator energized phased antenna (10) array is utilized as the excitation source for material/plasma processes. Each antenna element (10) of the array is driven by a separate solid state microwave power source. Very close and precise control of each solid state generator's phase and amplitude is provided to control the amplitude of the composite power node, and electromagnetic field distribution produced by the array which control is not readily possible with vacuum tube devices and systems such as microwave oven magnetrons. Utilizing the concepts of the invention the total power generated by the system may be easily controlled. The phase of the individual elements may be used to control the location of the power node of the plasma within a reaction chamber (12) and to move said power node within the chamber (12) with no mechanical movement or physical alteration of the processing apparatus. Because of the degree of control possible within the overall processes system of the invention plasma processing methods may be performed which were not previously practical because a high power density plasma can be concentrated at any desired location in the reaction chamber (12) or scanned across a desired region. These control features are lacking in currently available vacuum tube microwave devices. It is also probable that the overall cost of such a solid state based microwave power generators systems will be far less than that of comparable tube type microwave generators especially as fabrication and control technology progresses.

Abstract: A bundle of fiber-optic sensors that resist breakage, for use in measuring pH, CO₂, and O₂ concentration, and a method of making the same. Three optical fibers (15,17,19) are enclosed in a common polyimide sheath (13) and extend parallel to one another toward a distal end of the sensor, where they are bonded together in a mutually supportive array. At the distal end of one of these optical fibers is disposed a pellet (21) comprising a CO₂ analyte indicator molecule codissolved within a polymer matrix (22). A thin reflective surface of gold foil (20) is provided on the pellet such that incident light transmitted through the optical fiber and polymer matrix is reflected back into the optical fiber. The CO₂ polymer matrix absorbs light of a given wavelength to an extent dependent upon the level of CO₂ present. Similarly, on the distal end of a second optical fiber is disposed a pH pellet (25) comprising a pH analyte indicator matrix with a thin reflective gold foil (24) attached for reflecting light that has passed through the pH analyte indicator matrix back into the optical fiber. The pH analyte indicator matrix absorbs light of a given wavelength to an extent dependent upon the hydrogen ion concentration (pH level) of a surrounding fluid. The third optical fiber is used for measuring oxygen concentration. An O₂ indicator matrix (27) covers the distal ends of at least two of the three optical fibers; however, at least a portion of the pH optical fiber and the pH pellet are free of the O₂ indicator matrix, which is hydrophobic. The oxygen indicator matrix phosphoresces for an interval of time that decreases in proportion to the surrounding oxygen gas concentration. The phosphorescent and reflected light signals are transmitted to light detectors through the optical fibers for comparison to reference signals, so that the analyte concentrations can be determined.

Abstract: A flexible technique that is robust in the presence of noise and distortion is disclosed for locating and utilizing fiducial markings to locate predetermined areas within an image. Initially, a set of candidate markings is determined, one marking from within each of a plurality of predesignated areas of a scanned image. Thereafter, an estimate of a set of image distortion factors relative to an ideally registered image of the same type as the scanned image is derived. Predicted locations for the fiducial markings are derived using this estimated set of image distortion factors. If the difference in location between the actual location of any candidate marking and its predicted location is greater than a predetermined threshold, at least one such candidate is removed from the set of candidate markings. The estimation and removal processes are repeated, utilizing the new current set of candidate fiducial markings until all remaining candidate markings are within a predetermined distance of their predicted locations. Predetermined areas within the scanned image can thereafter be accurately located by combining the known location of the area within an ideal image with the final estimated set of image distortion factors. The predicted location may be further improved by using a weighted average of the ideal versus the actual fiducial marking differences, to account for local non-linear variations [FIG. 2].
