Title: Device for feeding waste air and/or combustion air to a burner or combustion chamber
Inventor: HUENING WERNER
IPC: F23C7/00
Filed: 1989-04-18
Granted: 1993-03-16
Abstract: Device for feeding waste air and/or combustion air to a burner or combustion chamber Abstract The device for feeding waste air and/or combustion air to a burner has an upstream cyclindrical swirl inlet system (inlet header 1) with feeder nozzles (8, 9) leading in tangentially.  The main nozzle (8) is here provided at a radial distance R from the burner axis on the inlet header (1), which distance is greater than the radius r of the combustion chamber (4).  By means of this increase in the swirl radius, a substantially higher swirl inten-sity can be generated at small throughputs.  In order to avoid an undue rise in the swirl at higher throughputs, a secondary flow (7), which is fed in via a control ele-ment (11), is introduced into the inlet header (1) via a secondary nozzle (9) tangentially and opposite to the main swirling flow.  Alternatively, the secondary flow (7) can also be fed to the inlet header (1) via inlet slots (14) substantially at right angles to the direction of the main flow.  In both cases, the tangential flow component of the main flow (6) is slowed down.  The con-trol element (11) in the secondary flow (7) is advanta-geously designed in such a way that the secondary flow (7) sets in only when the main flow throughput rises to 50% to 60% of the nominal throughput.

Title: Measuring curvature of transparent or translucent material
Inventor: MERSCH STEVE
IPC: G01B11/08
Filed: 1989-04-19
Granted: 1992-05-12
Abstract: ABSTRACT                 MEASURING THE CURVATURE OF TRANSPARENT OR TRANSLUCENT MATERIAL      An apparatus and method to determine with a high degree of precision the position of the inside  wall of  a  translucent  or  transparent  tube  comprises  a laser  beam at  a  wavelength  for  which  the material being measured  is  transparent  or  translucent and a directing means for aiming the laser beam toward the tube and normal to the axis of the tube while moving the aimed beam to traversely scan the tube.  A light detection  means,   positioned   to   receive   light polarized normal to the axis of the tube which light, having  been  reflected  by  the  inside  wall  and refracted by the tube, causes the detection means to generate  signals.   The  signals  are  processed  to analyze when the light beam is reflected by and when the  light  is  refracted  at  the  inside  wall  of  the tube.   The  apparatus  is  also  useful  in  connection with  finding  the  position  of  the  inside  wall  of curved material of generally uniform thickness.  The method includes the steps of aiming a beam of laser light polarized normal to the axis of the tube and intercepting the outside wall of the tube at a height substantially equal to the inside wall and normal to the  axis  of  the  tube  so  that  the  laser  light reflected by or refracted through the inside wall can be  detected  and  related to  the  transition  point between reflection and refraction as a measure of the radius of curvature of the inside wall.

IPC: H04R17/00
Filed: 1989-04-24
Granted: 1992-11-24
Abstract: ABSTRACT            An omnidirectional acoustic transducer achieves a broadband radiation or reception pattern with high efficiency by using several transducer rings located side-by-side with each ring comprising a plurality of radially directed individual transducer elements.  The transducer elements in each of the rings are tuned to a particular natural frequency and are designed accordingly.  Within each ring  the transducer elements are energized in phase with one another.  The natural frequency of the individual transducer elements differs from one ring to the other.

Abstract: ABSTRACT OF THE DISCLOSURE     A rotary blow molding machine is provided with a rotor, a plurality of separable mold units each consisting of mold halves into which a parison is extruded to mold a hollow product, and a label applying apparatus for applying a label to the product. A rotating shaft intermittently rotated by predetermined angles is located in parallel to a rotational axis of the rotor holding a plurality of split mold units. A link mechanism is secured to be swingable to the rotating shaft and a rubber suction cup for holding a label is secured to the front end of the link mechanism. The label is positioned on the inner wall of the split mold halves in open state by the combination of the intermittent rotation of the rotating shaft and the swinging movement of the link mechanism. The split mold unit is supported by a holder which is constructed so that when a slider-crank mechanism in association with a cam follower is positioned to a dead position, the clamping force is applied. A large force is not applied to the cam follower held by the rotor and the rotor is driven at a constant speed, thus exactly performing the positioning for the label application.

Abstract: "STEAMING PROCESS, INVOLVING A PAIR OF HORIZONTAL        WELLS, FOR USE IN HEAVY OIL RESERVOIR"     ABSTRACT OF THE DISCLOSURE    A pair of horizontal parallel co-extensive wells, one spaced closely above the other, are completed so that they extend through a heavy oil reservoir in close proximity to its base.          The upper well is referred to as the injector and the lower a the producer. Each well has a screened liner and an inner tubing string extending the length of the well.   Steam is circulated separately through each of the wells to heat by conduction the span of formation extending between the wells and establish fluid communication between them.   The circulation is conducted in through the tubing and out through the annulus at an elevated pressure that is less than fracture pressure.   The rate of production of effluent from each well is controlled to maintain its temperature just below saturated steam temperature.   Once communication is established, steam circulation in the producer is discontinued and the well is produced through the tubing.          Steam is then injected through both the annulus and tubing of the injector.   Condensate and oil are produced through the lower well.    Steam-assisted  gravity drainage  is the  mechanism thereafter used to heat the reservoir and produce the oil.          Production rate is controlled to maintain the temperature and pressure  of  the produced  fluid  just  below  saturated  steam conditions.

Abstract: The invention relates to a closure and/or control means for the tapping of liquid metal melt on a metallurgical vessel with a fixed refractory member and a refractory member which is sealingly movable relative to it in rotation and/or linearly, the two refractory members being provided with a respective circular cylindrical sealing surface and the two sealing surfaces being sealingly fitted within one another.   In order to ensure that in operation the free movability of the two refractory members with respect to one another is always maintained without the metal melt infiltrating into the vicinity of the annular gap between the two sealing surfaces it is proposed that the coefficients of expansion of the two refractory members be so matched to one another that in the operational state there is an annular gap between the circular cylindrical sealing surfaces of the two refractory members which forms a clearance fit which is still melt-tight.

Abstract: Human interferon-beta2A and interferon-beta2B are produced in purified form by recombinant DNA techniques. Two separate human genes have been identified which code for the production of IFN-.beta.2A and IFN-.beta.2B, respectively. The sequence of IFN-.beta.2A cDNA is established. These genes and cDNA have been cloned into mammalian cells with an SV40 early promoter sequence and such genomic clones are capable of pro-ducing IFN-.beta.2A and IFN-.beta.2B. The antiviral activity of such recombinant IFN-.beta.2A and IFN-.beta.2B is demonstrated as well as other biological activity identifying them as human interferons. It has been shown that IFB-.beta.2 secretion is induced in human cells by growth-stimulatory cytokines.

Abstract: A method for electrochemically removing tin oxide from a coater surface. A tin oxide coater is placed in an electrolytic bath to function as the cathode of a pair of cell electrodes. The tin oxide is electrolytically removed by either reducing the tin oxide to tin metal and then dissolving the tin, or creating a bubble of hydrogen gas at the coater surface/tin oxide interface. Pressure of the hydrogen gas forces the tin oxide to break away from the coater at the coater surface/tin oxide interface.
