Abstract: "CORROSION MONITORING"     ABSTRACT In an apparatus or installation having a metal part corroding in an electrolyte contacting the part, that part is a first electrode electrically insulated from a second electrode, for example another part of the apparatus, also contacting the electrolyte. No external electrical power is applied to the electrodes/electrolyte system.  The low frequency voltage between the electrodes is observed.  This voltage is a low frequency noise signal. Amplitude values of the signal are measured and subjected to an averaging computation yielding data indicating the corrosion rate of the first electrode and the nature of the corrosion.

Abstract: ABSTRACT:     A hydrogen gas generator system for converting water into hydrogen and oxygen gases, in combination with a mag-netic particle accelerator for voltage/current amplification. The hydrogen gas generator encompasses an array of plates immersed in water in a pressure tight enclosure.  Direct current voltage applied to the plates causes the hydrogen/oxygen gases to disassociate from the water molecule.  The upper portion of the container is a hydrogen/oxygen collection chamber for maintaining a predetermined gas pressure.  A hydrogen/oxygen gas mixture outlet means connected to the collection chamber of the gen-erator includes a magnetic polarizer for establishing a magnetic field and thereby imparting a magnetic potential to the hydrogen gas and the oxygen gas atoms as they are being pressure released from the collection chamber.  Attached to the gas outlet means is a non-magnetic conductive loop of tubing.  A coil wound around the tubing will have a voltage induced therein as the pressure velo-city polarized magnetized gas particles pass therethrough.  The induced voltage has utilization as an electrical power source. The hydrogen and oxygen gas may be utilized in a burner system or alternatively returned to the gas storage portion of the hydrogen generator in a closed-loop arrangement for re-cycling.

Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a method of testing and verifying a performance for insulation to ground of a disconnecting switch when breaking a charging current.  This disconnecting switch has a movable electrode and a fixed electrode which are arranged in a tank so as to face each other.  One of these electrodes is connected to an electrostatic capacity load and the other is connected to a power supply.  This test method comprises the steps of: applying a voltage from the power supply through the disconnecting switch to the load to cause the voltage to be trapped in the load; and applying a voltage of the polarity opposite to that of the trapped charged voltage from the power supply to the disconnecting switch to cause the discharge between those electrodes, thereby verifying the performance for insulation to ground.

Abstract: SPEECH RECOGNITION SYSTEM BASED ON WORD       STATE DURATION AND/OR WEIGHT  Abstract of the Disclosure A low cost, speaker independent, limited vocabulary, word recognizing microcomputer.  The microcomputer divides each spoken word into a series of word states, determines the length of each state and classifies each state as fricative, vowel-like, or silent.  The incoming speech pattern, in the form of an array of classified word states and an array of associated word lengths is then compared sequentially with a series of templates, defining the limited vocabulary stored in the microcomputer's memory. Each stored template includes an array of classified states, an array of lengths corresponding to the states and an array of weights corresponding to at least some of the states.  The state classifications of the incoming state array are compared sequentially with the template states of each template state array and where the classifications match, an error score is generated based on the difference in lengths between the template state lengths and the word state lengths.  The weights are used to permit recognition of a spoken word as a template word even when the array of states representing the spoken word is not identical to an array of states in any of the template words.
