Title: Essential fatty acid compositions and methods for the modulation of prostaglandin levels in mammals
Inventor: SEARS BARRY D
IPC: A61K31/23
Filed: 1989-09-27
Granted: 1995-01-17
Abstract: The modulation of prostaglandin levels can be realized through the dietary intake of specified ratios of activated Omega 6 essential fatty acids when combined with the appropriate amount of eicosapentaenoic acid (EPA), an Omega 3 fatty acid. The modulation of prostaglandins levels can be determined by changes in physiological parameters which are related to prostaglandin levels in mammals. Certain ratios of activated Omega 6 essential fatty acids and EPA can have significant physiological benefits, whereas other ratios demonstrate detrimental physiological effects in mammals.

Abstract: BAG CONSTRUCTION AND BAG PACK UTILIZING THE SAME            ABSTRACT OF THE DISCLOSURE        A plurality of bags, each having an upright handle at either lateral edge thereof, is formed into a bag-pack, and the bag-pack is retained on a supporting rack by providing upright slits in the handles of each bag through which arms of the supporting rack extend.  Unlike holes which are formed in the bag  handles,  upright  slits  do not cause weakening  of  the handles.   In addition,  the stacked handles of the bags are punched with a heated pin having a diameter no larger than approximately three thirty-seconds of an inch, to weld together the stacked handles of the bags, thereby permitting convenient mounting of the stacked handles on the arms of the supporting rack, without substantially weakening the bag handles.  The in-dividual  bags  are  readily  detachable  from  the  bag-pack, because the  pin  is uniformly heated by being placed  in a passageway in a block of metal heated to a temperature in the range of about 250-260°F.  The block passageway is long enough to receive at least a forward portion of the pin corresponding in length to approximately the stacked height of the bag-pack.

Abstract: An ultrasonic imaging agent is produced by a continuous sonication processing of an aqueous solution of heat-denaturable biocompatible protein. The solution is carefully preheated to a temperature of incipient protein denaturation without forming insolubilized protein. A gaseous fluid, preferably air, is added to the solution. In the sonication, the air-containing solution is foamed, increasing the formation and concentration of microbubbles, and the solution is further heated to insolubilize a portion of the protein, thereby encapsulating the microbubbles and forming particulate microspheres.

Abstract: A method of recovering fluorine, e.g. as hydrogen fluoride, from wastes of aluminum electrolysis furnaces, chemisorbents, adsorbents or absorbents, etc. in which the fluorine-containing material is subjected to pyrohydrolysis in an expanded fluid bed and the HF-containing gas is subjected to condensation or scrubbing for the removal of the HF therefrom. According to the invention, the exhaust gases from the fluidized bed are cooled by direct contact with solids which can be circulated in a separate cycle and are themselves cooled in a cooler, e.g. by contact with gas which is to be fed to the expanded fluidized bed. The circulated solids thus allow recovery of the sensible heat of the gas without diluting it.

Title: Method and system for digital measurement of acoustic burst travel time in a fluid medium
Inventor: WOODWARD WILLIAM STEPHEN
IPC: G01P5/00
Filed: 1991-02-06
Granted: 2000-11-14
Abstract: Fluid flow along a fluid path is determined by measuring the travel time between two transducers of two oppositely travelling acoustic burst waves. A pair of phase reference signals in phase quadrature are compared with the signals received by each transducer to determine the phase difference therebetween. The phase difference values are used to calculate the flow velocity.      After each phase difference determination has been made, the transducer drive signals are adjusted so that the launch time of the next pair of burst waves reduces the phase difference between the previously received signals and the phase reference to zero in the absence of any changes in flow velocity. The duration of each acoustic burst is sufficient to ensure that a predetermined number of successively received cycles in each burst are used in the phase comparison process.

Abstract: An   optical   polarization   modulator   has   an interferometric structure including, in at least one of two branches, a device causing the signal fractions in the two branches to assume an amplitude ratio depending on the value taken by a control signal, and a desired relative phase.   In one embodiment, the amplitude modulators are multiple quantum well asymmetric cavity Fabry-Perot devices biased in a complementary manner by binary signals, the levels of which are associated with voltage values such as to bring the devices to maximum absorption or maximum reflectivity conditions respectively; thus for each signal level only one of the two cavities reflects part of the received radiation.  The optical signal to be modulated is applied to one of the cavities with a first polarization state that is  maintained in the reflected radiation, and to the other cavity in a polarization state resulting in a second state of polarization in the reflected radiation.
