Title: Pipe connection structure and vacuum-type sewage collecting apparatus incorporating the pipe connection structure
Inventor: YAMAGUCHI KAZUO
IPC: E03F1/00
Filed: 1990-08-27
Granted: 2001-02-20
Abstract: A pipe connection structure for a vacuum-type sewage collecting apparatus for collecting sewage discharged from a multiplicity of houses or facilities in an accumulating tank through a vacuum sewage pipe the inner pressure of which has been made to be a negative level is disclosed. The vacuum sewage pipe includes a plurality of upper stream pipes and lower stream pipes fastened to each other in the branch-like shape. The pipe connection structure connects the upper stream pipe to the lower stream pipe formed in a sawtooth-like shape by alternating a downward-slope portion; which is arranged to slope gently downwards toward said accumulating tank, and a lift portion fastened to the lowermost portion of the downward-slope portion and arranged to be a steep upward slope. The upper stream pipe is connected to the lower stream pipe in a range in which a horizontal plane; which is positioned in contact with an upper end portion of the lower stream pipe at the position in which the downward-slope portion changes to the lift portion, is higher than the center of the lower stream pipe and at a position in which an opening of the upper stream pipe opened in the lower stream pipe is positioned diagonally upper than the pipe center of the lower stream pipe in a plane perpendicular to the pipe central axis. At least a portion of the opening is higher than the horizontal plane, and the upper stream pipe extends from the lower stream pipe diagonally upwards. By this arrangement, upper and lower stream pipes can be connected to each other in such a manner that the level difference between the two pipes can be significantly reduced and the back flow of sewage from the lower stream pipe toward the upper stream pipe can be prevented.

Title: Hydroacoustic ranging system
Inventor: ROUQUETTE ROBERT E
IPC: G01S5/30
Filed: 1991-02-11
Granted: 2000-05-02
Abstract: Digital processing systems and methods of hydroacoustic pulse communications in offshore seismic exploration systems provide more efficient surveys with less critical equipment.  Thus hydroacoustic transceiver transducers towed in a set of streamers behind a vessel are accurately positioned under variable operation conditions with a geodetic reference point for more efficiently and accurately monitoring echo points for seismically identifying underwater formations. Spacings between transducers are found by calculating from pulse arrival times the transit times of hydroacoustic pulses.  Predetermined pulse shapes and carrier frequencies above 40kHz are accurately determined upon receipt by digitally sampling waveshapes to determine shape and timing the reception of identified pulse shapes at transducers which are transmitted from other transducers for computing separations between sending and receiving transducers.  Pulse transit time averaging avoids precise synchronization for simpler apparatus.  The carrier frequencies and associated high pass filters for received pulses eliminate hydroacoustic noise.  The digital pulse sampling and timing techniques simplify communications with associated data processing systems for seismic analysis and provide compact on-location electronic systems coupled to the transducers.

Abstract: A method of determining the rate at which plastic granules are received by an extruder from a feed container having an outlet which opens into the inlet of the extruder. In which method granules are continuously fed to a supply container and consecutive charges of granules are intermittently fed to the feed container. The feed container is weighed before or at the beginning of or after or at the end of its filling operation. The time required to withdraw the material in the amount which has been determined by the weighing operations is measured, and the flow rate of the material is calculated from the amounts of material which have been received from the feed container in the measured intervals of time. A uniform feeding of material into the extruder will be ensured if granules and marginal strip material are supplied to the cyclone like container. The supply container is substantially used only as a mixing container and opens into a charge-holding container, which is provided between the supply container and the feed container. The granules of at least one component thereof and recycled marginal strips are continuously fed to the supply container. The feed container and the charge-holding container are weighed in intervals of time, and the feed rate of the granules of the at least one component is correspondingly increased or reduced when the measured total weight of the feed container and of the charge-holding container differs from a predetermined desired weight.

Title: Method for detecting maternally transferred drug metabolites in newborn infants
Inventor: OSTREA ENRIQUE M JR
IPC: G01N33/94
Filed: 1992-04-13
Granted: 1998-08-11
Abstract: An improved method for detecting the presence of drug metabolites in the meconium of newborn infants is described.  The method involves a single step extraction of the drug metabolites from meconium using a buffered aqueous solution containing methanol in an amount between about 10 and 30 % by volume and buffered to a pH between 6 and 7 and then assaying the extract individually for the presence of the drug metabolites.  The method is particularly useful for detection of cocaine, morphine, cannabinoid and amphetamine metabolites; however, any drug metabolite in the infant meconium can be tested if it is extracted by the solution from the meconium.  Various assay methods are used for the drug metabolites in the solutions derived from the meconium, including immunoassays, fluorescent assays and mass spectroscopy.  The method provides a means for early detection of drug presence in newborn infants which contribute to infant illness.
