IPC: G01N33/497
Filed: 1980-02-21
Granted: 1982-09-07
Abstract: ABSTRACT        The alcohol concentration in the blood is determined by analysing exhaled air.  Air is exhaled through a respiratory tube (1) past sensing means (3) for determining the alcohol content (Ra) and the moisture content (Rwa) of the exhaled air.  This determination is performed optically by measuring the absorbence, by the exhaled air, of light of different wavelengths, using two different filters (16, 17) on  a filter wheel (15).        The alcohol content of the exhaled air is calculated as a function of the term    , where RWl is the moisture content of the ambien t air.

Abstract: ABSTRACT      Method of regaining control over an abandoned well in the sea bottom, after it has erupted and is spilling hydrocarbon fluids into the sea water, by positioning directly above the well an emergency well-control vessel (30) having a fire-extinguishing-gas-dispelling system (60) and well-killing equipment (29), operating the system to prevent the ignition of the hydrocarbon fluids which reach the vessel, and lowering the equipment into the well to therewith control the well.  Preferably, the system includes blowers (32) and propellers (31), and the equipment includes a kill string (40) which is lowered into the well.  A weighted fluid is circulated down the kill string and up through the annulus of the well, whereby the fluid pressures in the wellbore are overcome by the greater hydrostatic pressure exerted by the circulating fluid, thus allowing the equip-ment to gain control of the well.  In use, the well has a wellhead (12) carrying a stack of blowout preventers (11).  Divers (37) connect the stack of blowout preventers to control lines (34) on the vessel. Then the preventers are operated to seal around the kill string before circulating the weighted fluid.  The kill string preferably includes a packer (44) which can be operated to packoff against the well casing (8).

Abstract: COMBINATION THERMOPLASTIC AND GLASS LOADED THERMOSETTING INJECTION MOLDING MACHINE AND      METHOD FOR OPERATING SAME ABSTRACT OF THE DISCLOSURE: An injection molding machine which is capable of inject-ing both thermoplastic compounds and glass loaded thermosetting polyester compounds, wherein the machine is capable of rapid conversion from its thermoplastic configuration to its thermosetting configuration, and vice versa.  The machine comprises an elongated charge forming barrel having a rearward thermoplastic feed opening, which is customarily supplied by pelletized thermoplastic material from a vertical feed hopper, and a thermosetting material feed opening extending into the barrel at a position forwardly of the thermoplas-tics feed opening.  When processing thermoplastics materials, a conventional, fully flighted plasticizing screw is installed in the barrel so that the pelletized material is conveyed forwardly from the rear feed opening, and plasticized for subsequent injection.  During thermo-plastics processing, the thermosetting feed opening is plugged.  To convert the machine to process the aforementioned thermosetting materials, the second feed opening is unplugged, and the plasticizing screw is exchanged fox a deeper flighted conveying screw having flights extending from the forward end thereof to just behind the unplugged, second opening.  A stuf-fer unit is then attached to the unplugged feed opening and dough-like glass loaded thermosetting material is forced through the second opening into the barrel by means of a reciprocating plunger, or the like. The thermosetting material is conveyed forwardly and mixed slightly as the screw rotates.

Abstract: C 11 RV-llP               METHOD FOR SEALING A DRYER     ABSTRACT. OF THE DISCLOSURE         A method for sealing a dryer against leakage of hot gases from within the dryer through joints between adjacent panels enclosing the interior of the dryer.  The method comprises fastening respective elongate enclosing members into abutment with mutually adjacent pairs of panels along the joints between them so as to form respec-tive enclosures between the enclosing members and the panels at such joints.  Thereafter, at a temperature less than the operating temperature of the dryer, a heat-resistant, gas-impermeable closed cell foam is injected into the enclosures through spaced perforations in the enclosing members so as to substantially fill the enclosures.  Thereafter, when the veneer dryer is operated at its normal elevated operating temperature, the temperature of the closed cell foam is thereby increased so as to expand the foam within the enclosures into tight sealing abutment with the joints to prevent gas leakage therethrough.

Various construction details which increase the efficiency of an array of rotor blades in the compression section are developed.  The annular flow path is contoured to cause the streamlines of the flow path to follow a pattern of varying radial curvature.  In one embodiment, a conical surface extending between the base of each airfoil on the inner wall causes a flow path contraction and a cylindrical surface on the outer wall facing the tip of each airfoil enables close clearances.

Abstract: METHOD OF TREATING EDIBLE OIL WITH ALKALI    USING INTERFACIAL   SURFACE MIXER     ABSTRACT     A method of treating edible oil comprising: driving a stream of about 70 to about 99.9 wt.% of an edible oil and about 0.1 to about 30 wt. % of a 0.01 to 6.5 Normal aqueous alkali solution, through an interfacial surface mixer at a predetermined mean droplet diameter of the aqueous alkali (phase) in said stream, which is related to a predetermined Reynolds number, said stream having a mixing temperature of from about 3°C to about 60°C, and thereby mixing and reacting said oil and said alkali to provide a reacted aqueous alkali phase and a reacted oil phase, and then separating said reacted oil from said reacted aqueous alkali.     The residence mixing and reacting time of the oil and alkali stream in the mixer is about five seconds: thus, the method of this invention is faster and more efficient than corresponding prior art oil alkali treatment processes.  Neutral oil loss is reduced up to 80% and mixing energy required is reduced up to 98% over corresponding prior art.          The predetermined alkaline solution phase droplet size generated in the mixer is calculated to be small enough to react with the oil and thereby provide the desired results, i.e., the refining of crude oil, the dewaxing of refined oil or the combined refining and dewaxing of crude oil.  The droplet should however not be so small so as to generate an emulsion.
