Title: Electronic remote data recorder for electric energy metering
Inventor: VENKATARAMAN KRISHNAN

Granted: 1992-03-31
Abstract: ELECTRONIC REMOTE DATA RECORDER         FOR ELECTRIC ENERGY METERING           ABSTRACT OF THE DISCLOSURE     An electronic remote data recorder records pulses representing usage of a commodity such as, for example, water, gas or electricity from a plurality of consumers.  The data from each consumer is stored in a respective data storage device.  Each data storage device is associated with an interval data directory which stores the time  at which significant events, affecting the data in the data storage device occurred.  Thus, the data in the data storage device is compact, without requiring a contemporaneous time code for each data item.  Data integrity is retained over a period of power outage in a non-volatile storage device.  Initial, post-installation programming is enabled by comparing the data pattern in the non-volatile storage device with a predefined data pattern that is expected to exist once the apparatus has been programmed.  A write-protect switch prevents programming during an incoming call after the initial programming.  Programming from an external source may be permitted during a telephone call initiated by the data recorder itself.  A telephone line-sharing device permits a plurality of remote data recorders to share a single telephone line without interfering with each other.

Abstract: ABSTRACT    A method and an apparatus for determining the surface tension between a gas and a liquid, and wherein the surface tension of a film established on the surface of a bubble in a medium may be calculated.  A liquid medium such as an aqueous medium is provided in a chamber.  The container is constructed so that an air bubble may be formed in the liquid medium in the chamber and a film of a material, such as a surfactant material, can then be formed at the air-liquid interface.  The chamber is also constructed so that the pressure of the liquid medium may be varied.  On increasing the pressure of the liquid medium, the bubble volume and its surface area are reduced.  Thus, the interfacial film is compressed, and alternatively, when the pressure of the liquid medium is reduced, the film is expanded by the expanding of the bubble.  The chamber provides a complete enclosure so that the liquid medium and the surfactant are not exposed to the atmosphere.  The surface tension can then be determined on recording the shape of the bubble by way of a computer calculation. Dynamic as well as static surface tension vs area relations can be obtained by adjusting the compression and expansion cycling speed.  The invention is especially suitable to study surface active components relating to pulmonary surfactant because the bubble is leak proof and thus mimics the situation in the lung. Unlike known apparatus for testing surfactant, the device is of a very economical structure and may be operated without highly technical training.

Granted: 1990-12-04
Abstract: Abstract of the Invention:           An  intake  hose  on  one  sidewall  of  the machine  communicates  with  a  source  of  negative pressure to create a powerful  suction air  stream that draws particulate materials through the hose and propels them into a chamber where they separate from the air stream and charge by their own momentum directly  into  a  discharge  auger  assembly on  the opposite  sidewall  of  the  machine.    The  auger assembly joins with the sidewall of the machine at an  upwardly  and  outwardly  inclined  attitude  for elevating the materials into a suitable receiving truck or trailer alongside of the machine,  and a lower  longitudinal  portion of  the  assembly which adjoins the sidewall is open along its length to facilitate  the  unimpeded  reception  and  entry  of particulate materials from the hose directly into the auger.   The auger assembly includes a tubular housing  surrounding  an  internal,  longitudinally extending auger,  and a pair of  successive outlet ports in the housing adjacent the upper and outer end of the assembly are controlled by independently functioning,   spring-biased,   sealing  doors  that assist  in  providing  an  airlock  in  the  assembly during  operation  to  prevent  the  admittance  of power-robbing ambient air to the separating chamber via the auger assembly.

Abstract: Abstract Disclosed is an apparatus and method for the treatment of the symptoms of obstructive prostatism.   The apparatus comprises an expandable dilatation catheter and an axially elongate sheath,  adapted for transurethral insertion via the  external  opening  of  the  urethra.    the  sheath  is ellipsoid in cross-section,  and provides an initial path through which the catheter and a standard cystoscope lens is  guided.    Disposed  near  the  proximal  end  of  the expandable  dilatation  portion  of  the  catheter  is  a plurality of irrigation ports.  A saline solution travels through an irrigation conduit and is secreted through the irrigation ports so as to flush away blood, etc., away from the lens of a cystoscope and provide the urologist with an unobstructed view of the dilatation catheter and external urethral  sphincter muscle.   Once the catheter has been properly positioned with respect to both the bladder neck and the sphincter, the dilatation balloon may be inflated to force open the affected prostatic urethra and eliminate the obstruction.

Abstract: ABSTRACT An engine intake screen assembly as provided.  A rotatable screen has a continuous peripheral skirt which telescopes with an upstanding housing ring-like flange so as to create a serpentine entry path for grass and other foreign matter trying to enter at the seam between the screen and the inlet.  Entry can be further restricted through the use of a radially outwardly directed ring extension on the screen and/or a guard ring member.  These parts can combine to form a trap pocket and/or to increase the serpentine nature of the entry path.  In one version, the grass will form its own seal in the trap.

Abstract: ABSTRACT      The present invention is an improvement to a liquefaction process for natural gas, wherein refrigeration for the liquefaction process is provided by two closed-loop refrigeration cycles.  The first or low level refrigeration cycle uses either a mixed refrigerant or a single component refrigerant as the heat pump fluid, and the second or high level refrigerant uses a mixed (multicomponent) refrigerant as the heat pump fluid.  In the liquefaction process the second or high level refrigeration cycle cools the low level heat pump fluid.  The low level refrigeration cycle cools and liquefies the cooled natural gas feed.  The improvement to the process is the use of an absorption refrigeration cycle to precool the natural gas feed, the low level heat pump fluid, the high level heat pump fluid and, if required, the deep flash recycle. Heat to drive the absorption refrigeration cycle is provided by the exhaust gas from one or more drives for the compressors in the process.
