Title: Method for modifying the swirl motion of a liquid in a swirl chamber of a nozzle and swirl generator for nozzles
Inventor: SLOWIK GUNTER
IPC: B05B1/34
Filed: 1999-03-17
Abstract: The invention relates to a method for modifying the swirl motion of a liquid in the swirl chamber of a nozzle and swirl generator for nozzles. Such nozzles are used especially in industrial burners, oil burners and installations for cleaning flue gas and spray-drying food. Owing to the disadvantages of state-of-the-art technology, the invention aims to provide a method and a corresponding nozzle which make it possible to adjust the mean droplet diameter at a constant volume flow rate or to maintain the droplet spectrum constant in case of adjustment of the volume flow rate. To this and the invention provides for the partial flows (T1, T2) to be distributed across supply channels (4a, 4b, 4c, 4d) which differ in terms of their cross-sections at their point of connection with the swirl chamber (3). When the partial flows (T1, T2) are divided across more than two tangential supply channels (4a, 4b, 4c, 4d) the cross-sections are constituted by the sum of cross-sections of the supply channels (4a, 4c or 4b, 4d) branching off the corresponding partial flow (T1, T2). As a result the sums of the cross-sections at the point of connection (S1, S2) of the partial flows (T1, T2) with the swirl chamber (3) are different.

Abstract: The invention relates to a method for producing slush from liquefied gas. According to said method, solid crystals are formed and mix or are mixed with the liquefied gas to produce slush. These solid crystals are produced from liquid particles which are released into or enter a gas atmosphere under pressure, the temperature of the gas atmosphere being below the freezing point of the liquid particles. The invention also relates to a device for producing slush from liquefied gas in a cryostat container (1) which is partly filled with the liquefied gas which mixes with the solid crystals to produce slush. The device has an atomising device (2, 12) for producing liquid particles from the liquefied gas supplied to it. Said liquid particles enter a gas atmosphere which exists above the liquefied gas in the container (1). The temperature of said gas atmosphere is below the freezing point of the liquid particles.

Title: Solid state tower beacon lamp

IPC: H01S3/09
Filed: 2000-11-21
Abstract: THE CURRENT STATE OF SONOLUMINESCENCE THEORY HAS PROVEN THE EFFECT EXISTS AND  HAS BEEN QUANTIFIED TO THE BUBBLE DIAMETER BY MANY MODELS. THE MOST INTERESTING OF THESE MODELS IS THE  ONE PROPOSED BY CLAUDIA EBERLAIN, UNIVERSITY OF ILLINOIS, DEPT. OF PHYSICS. 1995. THE POSTULATED MODEL IMPLIES THAT LIGHT EMISSION IS NOT A PRODUCT OF ADIABATIC  GAS COMPRESSION, BUT OF WAVEFRONT INTERACTION WITH THE ZERO POINT ENERGY PLENUM. QUANTUM THEORY HOLDS THAT THE  VACUUM OR AETHER, CONTAIN INVISIBLE VIRTUAL PHOTONS THAT MANIFEST THEMSELVES AS "QUANTUM FLUCTUATIONS".  FURTHERMORE, THAT THE EFFECT KNOWN AS SONOLUMINESCENCE IS THE FIRST OBSERVABLE CONFIRMATION THAT WE CAN  PRODUCE RADIATION FROM A VACUUM, OR ZERO POINT ENERGY PLENUM. (ZPE). THE WAVEFRONT GENERATED IN THE VAN DER  WAALS DOMAIN INTERRACTS WITH THE ZPE DOMAIN AT SOME POINT IN THE BUBBLE COLLAPSE, AT A PLANCK LENGTH OF 1.6 X 10 -33 CM. THIS WOULD IMPLY THAT THE EMITTED WAVELENGTH OF THE RADIATION IS SOMEHOW RELATED TO THE WAVE  FUNCTION OF THE COLLAPSING BUBBLE BOUNDARY OR WALL. ALL KNOWN OBSERVATIONS TO DATE HAVE BEEN GENERATED WITH AUDIO SPECTRUM  EQUIPMENT AND TRANSDUCERS IN A WATER MEDIUM. VARIATIONS OF THE EXPERIMENT HAVE BEEN TRIED WITH APPLIED MAGNETIC  FIELD, SOUND MODULATION, TEMPERATURE, AND GAS DOPING OF THE WATER MEDIUM, WITH VARIOUS RESULTS, NONE OF WHICH HAVE  PRODUCED SIGNIFICANT RESULTS. IF THE POSTULATE IS CORRECT, EMISSION OF PHOTONS SHOULD BE OBSERVED WHEN TWO  CONVERGING WAVES INTERRACT IN A SOLID MATERIAL HAVING A HIGH VAN DER WAALS FORCE IN A MATERIAL. THIS  RADIATION WOULD HAVE ITS' WAVELENGTH AND AMPLITUDE DETERMINED BY MEDIUM DENSITY AND APPLIED SIGNAL WAVE FUNCTION, PROVIDING THAT THE MEDIUM IS OPTICALLY TRANSPARENT. ORDINARY GLASS WOULD BE AN OBVIOUS CANDIDATE AS A SUITABLE  MEDIUM. IT HAS HIGH VAN DER WAAL    FORCES, IS OPTICALLY TRANSPARENT AND IS READILY AVAILABLE. IT IS PROPOSED AT THIS TIME, THAT THE EMISSION SPECTRUM CAN BE CONTROLLED VERY  ACCURATELY IN A GLASS MEDIUM. THE CONTROL PARAMETERS ARE IN THE COMPLEX FOURIER DOMAIN AS MODULATED DRIVING  SIGNAL COMPOSITES. OUTPUT EMISSION WILL BE A FUNCTION OF WAVEFUNCTION OF THE DRIVING SIGNAL TO THE PIEZO-TRANSDUCERS, AS SHOWN IN THE DRAWINGS. THIS COMPOS ITE SIGNAL WILL BE GENERATED IN THE DIGITAL DOMAIN WITH SOFTWARE, AND WILL  DRIVE A PAIR OF LINEAR AMPLIFIERS THAT WILL IN TURN, DRIVE THE PIEZO-ELECTRIC TRANSDUCERS. THE TRANSDUCERS ARE ANNULAR IN  GEOMETRY WITH AN OPENING IN THE CENTER. A BOLT CAPTURES THE TOP AND BOTTOM TRANSDUCERS WITH THE GLASS LENS  BODY IN BETWEEN, PROVIDING A STATIC PRE -LOAD FORCE TO THE GLASS LENS BODY. THIS TECHNOLOGY WILL ALSO FIND IMMEDIATE APPLICATIONS IN IMAGE REPRODUCTION  ENGINEERING, COMPUTER DISPLAYS, TELECOMMUNICATIONS MULTIPLEXING, SONG-CHEMISTRY, AND RUNWAY LIGHTING  APPLICATIONS.

Title: Method and apparatus for generating automatic greetings in a call center
Inventor: CHAN NORMAN C
IPC: H04M3/51
Filed: 2001-01-05
Abstract: A call center includes a message playback unit for playing back a prerecorded greeting during an outgoing call while a call classifier unit within the call center processes an audible signal received from a remote party location. A call processing unit places a call to a remote party location via a communication network to attempt to elicit a desired response from the remote party. The call classifier then processes an audible signal received from the remote party location to determine whether or not the call was answered by a live party. The prerecorded greeting is then played while the call classifier is simultaneously processing the audible signal. If the call classifier determines that the call was answered by a live party, the call processing unit completes a talk path between the remote party location and a local agent at the call center who handles the remainder of the call. The call processing unit will normally wait until the greeting has ended to complete the talk path. If the call classifier determines that the call was not answered by a live party, the call processing unit will terminate the call.
