Title: Hearing-adapted quality assessment of audio signals
Inventor: SEITZER DIETER
IPC: H04S1/00
Filed: 1997-10-02
Abstract: In a method for assessing the quality of an audio test signal (14), which has been derived by coding and decoding an audio reference signal (12), the audio test signal (14) is compared with the audio reference signal (12), as it were, behind the cochlea of the human ear. All masking effects and the transmission functions of the ear are equally applied to the audio reference signal (12) and to the audio test signal (14). To this end, the audio test signal (14) is broken down according to its spectral components by means of a first bank of filters (20) consisting of filters overlapping in frequency and defining spectral regions, said filters having differing filtering functions, which have been determined on the basis of the excitation curve of the human ear with respect to the respective filtered middle frequency. The audio reference signal (12) is also broken down according to its spectral composition into partial audio reference signals by means of a second bank of filters (16) coinciding with the first bank of filters (2). Subsequently, a level difference by spectral region is formed between the audio test signals (22) belonging to the same spectral regions and the audio reference signals (18). To assess the quality of the audio test signal (14), a detection probability is determined on the basis of each level difference so as to pick up any decoding error of the test signal (14) in the spectral region concerned.

Abstract: An apparatus and method for frying food is comprised of a housing provided with a receiving opening in which foodstuff to be fried is inserted. The foodstuff is directed to a perforated frying basket which is displaced upon actuation of a switch by the user into a frying pot containing hot oil. While the basket is in the frying pot, it is being shaken to provide more even cooking and to prevent the foodstuff from sticking together. After the frying cycle the frying basket is displaced to a position above the frying pot where the basket is again shaken to drip oil from the foodstuff and the basket into the frying pot. The basket is then conveyed to a discharge position where a chute directs the fried foodstuff to a discharge opening where a container has been placed to receive the fried foodstuff.

Title: Atomizer wheel with improved nozzle for rotary atomizers
Inventor: ADKINS BRUCE D
IPC: B05B3/10
Filed: 2000-03-22
Abstract: The present invention pertains to an improved nozzle for use in wear-resistant rotary atomizers and to atomizer wheels containing said improved nozzles.     Said atomizer wheels and nozzles have the same wear resistance as the ones described in the prior art or even better, but at the same time, the nozzles have been improved to provide microspherical particles with a very narrow particle size distribution.   The nozzle of the present invention comprises wear-resistant sintered material and has a flow channel in the shape of a vertical slot. Said vertical slot may optionally be uniformly rounded. It was found that when these improved nozzles are used for spray-drying suspensions, microspherical particles with a narrower particle size distribution are obtained than when using nozzles with cylindrical flow channels.

Title: Moisture insensitive electroluminescent phosphor
Inventor: KLINEDINST KEITH A
IPC: B01J2/30
Filed: 2000-04-11
Abstract: A phosphor particle has thereon a moisture resistant treatment of a metallic nitride. By moisture resistant is meant a condition allowing the phosphor particle to function in a humid atmosphere for a significantly longer period of time than an untreated particle. The method of making such phosphors comprises the steps of introducing an inert gas into a reaction vessel; charging phosphor particles into the reaction vessel;  heating the reaction vessel to a reaction temperature. introducing a first precursor compound such as triiosbutyl aluminum and a second precursor compound such as dimetylamine into a second reaction vessel to form a nitride precursor. The nitride precursor is hexakis(dimethylamido)dialuminum. The nitride precursor is introduced into the first reaction vessel in a manner to avoid restrictive reactions. A a co-reactant is introduced into the reaction vessel, the inert gas flow, co-reactant flow and precursor supply are mainitained for a time sufficient to make the phosphor particles moisture resistant. The nitride treated phosphor particles produced by this method, which can include the deposition of a nitride coating on the particles, have excellent efficacy ratings and strong luminance values in lamps after 100 hours use in high humidity (i.e., >95%).  By avoiding restrictive reactions and by synthesizing the nitride precursor on stream, the method and apparatus can be used to manufacture commercial quantities of coated phosphors at an economical cost.
