Title: An automatic system to feed burners with diesel or light fuel-oil
Inventor: SANZ PEREZ ANTONIO
IPC: F02B3/06
Filed: 1992-09-23
Abstract: ABSTRACT SUMMARY OF THE INVENTION            AN AUTOMATIC SYSTEM TO FEED BURNERS WITH        DIESEL OR LIGHT FUEL-OIL       From a  fuel  storage  tank  (13),  a  filter  (1)  is installed to prevent any obstruction, followed by a vacuum gauge (2) and a motor-driven pump (3) to deliver the fuel to the burner (12): immediately prior to said burner, there is a pressure relief valve (11). Said vacuum gauge (2) controls the suction of the motor-driven pump (3) and the level of dirt in the filter (1). A retention valve (4) is installed following said motor-driven pump (3), with a pressure gauge (5) and a pressurestat (6) fitted with two contacts, one for maximum and minimum or service contact, and the other for safety, to prevent fuel spillage in case of a pipe breakage, shutting  off  the  motor-driven  pump  (3)  to  which  the pressurestat (6) is connected by an electrical control (7). A safety valve opens if pressure is excessive and returns the fuel to the storage tank (13) while an expansion tank (8) keeps continuous pressure in the circuits even though the motor-driven pump (3) is operating intermittently. Any excess fuel is eliminated from the burner (12) by a return system fitted with a retention valve (16), through the pipe (14) situated upstream from the relief valve (11).       Figure 1

Title: Continuous speech processing system
Inventor: GILLICK LAURENCE S
IPC: G10L15/32
Filed: 1991-06-17
Abstract: 2085895 9200585 PCTABS00010 The speech (40) to be recognized is converted from utterances to frame data sets (42), which are smoothed (46) to generate a smooth frame model over a predetermined number of frames. A resident vocabulary is stored within the computer (50) as clusters of word models which are acoustically similar over a succession of frame periods. A cluster socre is generated by the system, which score inlcudes the likelihood of the smooth frames evaluated using a probability model for the cluster against which the smooth frame model is being compared. Cluster sets having cluster scores below a predetermined acoustic threshold are removed from further consideration. The remaining cluster sets are unpacked for determination of a word score for each unpacked word. These word scores are used to identify those words which are above a second predetermined threshold to define a word list which is sent to a recognizer for a more lengthy word match.

Title: Method for identifying vibrotactile perception thresholds of nerve endings with inconsistent subject response rejection
Inventor: BRAMMER ANTHONY J
IPC: A61B5/103
Filed: 1993-07-19
Abstract: ABSTRACT        A method of identifying vibrotactile perception thresholds of nerve endings at a skin site of a subject to  assess  sensory  change  in  tactile  sensory  nerve function is disclosed.   The method comprises applying two known frequencies in the frequency ranges mediated by three  types  of  nerve  ending groups  to  obtain  a sensory response from a subject as the amplitude of these frequencies is increased and decreased.   These responses are converted into threshold signals of which threshold shift values are established,  the deviation of  which  is  then  compared  with  a  stored reference inconsistency  limit  value  which  was  derived  from healthy   intra-subject   variability,   in   order   to determine the acceptanc  or rejection of the threshold signal  values  derived  from  the  subject.    If  the threshold  signal  valu?   are  rejected,  the  test  is repeated  several  times  until  acceptable  threshold signal values are obtained thereby providing  a true tactogram response of the subject.

Title: Visual immunoassay method for the detection of ligands, based on the use of opaque plastic supports
Inventor: SANTIZO LESCAILLE CARLOS A
IPC: G01N33/543
Filed: 1993-09-03
Abstract: ABSTRACT            Visual Immunoassay Method For The Detection Of Ligands, Based On The Use Of Opaque Plastic Supports The present invention is related with the field of Immunology, and particulary with an immunoassay method for ligand detection in fluid bodies, using plastic supports.       The technical objective of the invention consists of a manual immunoassay method that provides high sensitivity and specificity, and reagent economy, for the detection of ligands in fluid bodies, using opaque white plastic supports. The latter contain either antigens or antibodies, immobilized on low-depth microwells. The detection of the respective ligand binding partner (antibodies or antigens, respectively) is evidenced using reagents conjugated with monodisperse colloidal gold, being the signal amplified "in situ" by physical developers, based on silver ions. The samples, and all liquid reagents are placed in contact with the microwells, finally obtaining metallic colored insoluble reactions of very high contrast, that can be easily interpreted in a visual fashion.   This method can be employed for the detection of any type of antigen (including small molecules with discreet epitope structure) or antibody.

Title: Blood pressure monitoring in noisy environments
Inventor: PHILLIPPS PATRICK G
IPC: A61B5/022
Filed: 1992-03-31
Abstract: Several techniques are provided for aiding in the discrimination of detected bilogical signals indicative of blood pressure from detected signals not indicative of blood pressure (e.g., noise). A  threshold, based predominantly on a level of noise, is developed and used in the discrimination. A second threshold, based predominantly on levels of previously detected biological signals, is developed and additionally used to help discriminate the biological signals from noise. The biological signals are detected during a selected portion of a cardiac cycle, and additional signals detected outside of the selected portion of the cycle are applied to the detected signals. Another threshold may be developed based predominantly on a level of signals sensed by a transducer positioned to preferentially sense noise; the transducer is positioned so that the noise that it detects is related to noise that is detected during the detection of the bilogical signals. Blood pressure is measured during periodically scheduled measurement cycles, and a measurement cycle is suspended if noise exceeds a predeteremined level. The times at which the detected signals (i.e., the signals indicative of blood pressure and the signals not indicative of blood pressure) are processed during a given cardiac cycle are selected based at least in part on the pressure of the cuff.  The biological signals indicative of blood pressure that are detected during a current measurement cycle are used to at least in part determine the times at which the detected signals will be processed during a succeeding measurement cycle.

Title: Method and apparatus for detecting the position of fluid-fluid interfaces
Inventor: GABELICH STEPHEN A
IPC: C25C7/06
Filed: 1994-02-10
Abstract: METHOD AND APPARATUS FOR DETECTING THE POSITION OF FLUID-FLUID INTERFACES                  ABSTRACT OF THE DISCLOSURE         Precise information is obtainable concerning the position of a fluid-fluid interface (28, 33), such as between a gas and a liquid or between liquids.  Such information is important  for the control and automation of molten metal refining processes.  Specifically, in an electrolytic process for removing magnesium from molten aluminum, knowledge of the vertical position of an interface (33) between the electrolyte and  the  magnesium  and  an  interface  (28)  between  the electrolyte and the aluminum facilitates the automatic removal of the purified metals when drained or drawn from the furnace. Heat  energy  is  conducted  through  a  thermocouple-heater assembly 34 to a thermocouple (38) located at its tip (36). The equilibrium temperature at the thermocouple junction is dependent upon the heat loss through tip (36).  When the tip comes in contact with a fluid of different thermal conduc-tivity, as between molten matter (29) and electrolyte (30), the equilibrium temperature at tip (36) and, thus, of the thermocouple junction will change. This change in temperature is used to determine the level of the liquid-liquid interface between  molten matter  (29)  and  electrolyte  (30).   This information is used to determine when the drawing of further molten material from the furnace is to be terminated, so that aluminum purified in the refining process and previously drawn through an outlet (26) will not be contaminated.
