Inventor: LEON ROBERT L
IPC: G01M3/24

Abstract: A method and apparatus for on-line detection of leaky emergency shutdown or other valves in a fluid transport system having an upstream pipe, a downstream pipe and the valve connected between the upstream pipe and the downstream pipe for controlling fluid flow through the system. The valve has at least one upstream seal and at least one downstream seal and an inner cavity effectively isolated by the seals from the fluid flow stream through the system. The apparatus comprises a first transducer in fluid communication with the fluid flow stream at at least one of: a predetermined distance upstream of the upstream seal; and a predetermined distance downstream of the downstream seal. The first transducer is for sensing pressure pulsations resulting from at least one of: dynamic energy due to fluid flow through the transport system; and transient energy within the fluid in the transport system after the valve is closed and for generating representative electrical signals as a function of time. A second transducer is in fluid communication with the inner cavity of the valve for sensing substantially simultaneous pressure pulsations within the inner cavity and for generating second representative electrical signals as a function of time. An analyzer receives the first and second electrical signals and generates at least one of: a frequency response function; and a coherence function. The generated function is sufficiently averaged to provide a meaningful measure of the degree to which the two electrical signals are related to thereby indicate whether, and to what extent, sensed pressure pulsations within the fluid transport system are passed through at least one of the seals to the inner cavity.

Abstract: The present invention is for providing an antenna device in a portable radio, capable of transmitting and receiving in frequency bands used in two different communication systems without the performance irregularity even in the case of the mass production. By having the inductance per unit length along the elongating direction of the upper antenna element larger than that of the lower antenna element, the entire antenna element is resonated at a first frequency f1 as a quarter wave ground antenna element and is also resonated at a second frequency f2 lower than the frequency three times as much as the first frequency f1 as a three quarter wave ground antenna. Since the antenna element is formed with an antenna pattern printed on a printed wiring board, antenna elements with the same shape can be obtained, and thus the antenna performance irregularity cannot be generated even in the case of the mass production.

Abstract: The invention relates to a method of extracting water from a water-containing product that is in contact with air of a first temperature circulating in an at least essentially closed drying chamber (30), wherein water vapour is emitted by the product and enriched in the circulating air.  The method is characterised by compressing water-enriched air, therewith raising its temperature, by cooling the compressed air by an exchange of heat with the air in the drying chamber (30) or the air in another drying chamber, wherein water condenses out as a result of said cooling process, and by separating the water condensate from the cooled compressed air and expanding the cooled air and returning the air to the drying chamber (30) and carrying away the water condensate.  The invention also relates to apparatus for carrying out the inventive method.  This apparatus includes a compressor (1) having an inlet for air of a first temperature, and an outlet for compressed air of a second temperature.  The apparatus includes a heat exchanger (4) that has a compressed air inlet which is connected to the compressor outlet and to an outlet for water-phase condensate and compressed air respectively.  The apparatus further includes a liquid separator (6) having an inlet for air cooled in the heat exchanger (4) and the water-phase condensate respectively, said liquid separator (6) having a water-phase outlet and a condensed air outlet, and further includes an expansion device (11) which is connected to the condensed air outlet of the liquid separator (6).

Abstract: An antiskid control valve for use with an air brake system on a vehicle which also includes an antiskid control system capable of detecting actual or potential locking of the braked wheels and providing a signal to actuate the antiskid valve. The antiskid valve provides for unrestricted operation of the brakes by delivery of air from a reservoir to brake actuating chambers until a signal is received of a potential wheel lock at which time the brakes are automatically released and further delivery of air from the reservoir to the brake chambers is prevented until the braked wheels resume rotational speed. After the wheel lock condition is avoided, the brakes are reapplied at a controlled rate due to a restriction in the line delivering air from the reservoir to the chambers for operation of the brakes.

Abstract: The present invention is directed to a method and apparatus for heat generation or heat exchange in which a primary medium emits heat while passing through an evaporator in which there is a heat-transfer medium which thereby evaporates or boils and thereby increases the pressure of the heat-transfer medium. Once the pressure has increased, it is transferred to a condensor where a secondary medium is heated from the condensation of the heat-transfer medium. The method and device according to the present invention increase the efficiency, particularly when the primary medium is at a low temperature, by intensifying the heat at least in a portion of the evaporator.

Abstract: Disclosed is an overload protective circuit for an electric motor which is adaped to monitor and track motor temperature as a function of an operating parameter, namely armature current. The motor's armature current is sensed and converted to a multi-bit digital signal which is used to address a programmable read only memory (PROM) which has been pre-programmed with discrete digital values of temperature for a plurality of armature currents for the motor being protected. The digital address signal for the armature motor current is periodically updated at a relatively rapid rate and depending upon the armature current sensed, multi-bit temperature values are outputted from the PROM to a digital latch which operates a relatively slower rate to output another address back to the PROM so as to predict what the temperature will be at the next time increment based on the present current value and the present temperature. When predetermined temperature levels are reached, two bits of the PROM's output are respectively adapted to provide an alarm signal, and then a subsequent trip signal which is adapted to deenergize the motor.
