INSTRUCTIONS: This application is based on the benefit of the priority of the U.S. Provisional Patent Application No. 61/480,428, filed on Apr. 29, 2011. Revealing content. TECHNICAL FIELD The present disclosure relates generally to apparatus and methods for fabricating glass articles 'and more particularly to apparatus for redirecting glass fluid within a conduit, and to fabricating glass articles. Method 'The method comprises the steps of redirecting the fluid profile of the molten glass within the conduit. [Prior Art] A glass manufacturing system is generally used for molding various glass articles such as glass plates for liquid crystal displays (丨iqUid cryStai diSpiay; LED). For example, conventionally, molten glass is poured into an isopipe, a molding container, a debiteuse, or other molded structure in which a glass ribbon (glass ribb〇n) is formed by a pull-down process, for example, Melt pull-down (fusi〇nd〇wn_draw) process. The glass ribbon can then be divided into a plurality of panels, for example: an LCD glass panel is provided. Glass for use in flat glass applications (especially for LCD panel applications) 201242919 Glass is increasingly demanding. There are two interrelated properties, both of which are related to the process of agitating the glass in the mixing chamber: the defect in the flatness of the finished glass surface (known as "mura" or "cord" "), and precious metal particle impurities (inclusi〇ns), these metal particle impurities are caused by the corrosion of the stirring knife and the corrosion of the stirring chamber wall. Corrugati〇n—c痕rd—common in: the glass homogeneity (h〇m〇genehy) is insufficient or the glass is insufficiently mixed in the finished product before the finished product is delivered. The resulting change in panel thickness translates into a change in the liquid crystal gap, which can cause erroneous operation. The impurity of the precious metal causes the discontinuity of the glass panel body, resulting in a defect of the black spot (bIacJcsp〇t) j of the finished LCD product. [Area] The purpose of the stirring system is to reduce the chemical change in the glass, and the chemical changes are the melting process. Abnormal growth processes: batch melting, decomposition products from refractory sump, etc. Optimal glass agitation is the equilibrium behavior between the two phenomena: homogenization of broken glass (h〇m〇 Both genizati〇n) and material corrosion, both of which are enhanced by increasing the shear between the stirrer blade and the wall of the agitating chamber. For the quality of the glass, the glass homogenization is enhanced and the material is corroded. Disadvantages: A month, people have found a solution to improve glass homogenization: without increasing the speed of the stir bar. The numerical model results and the oil model indicate that the glass entering the mixing chamber from the bottom of the conduit is less authorized. Corpse 5 201242919

以產生熔融玻璃124之步驟。如第3圖所圖示，（例如） 藉由第-導管132’熔融麵124接著被送至澄清腔室 130中。該方法接著包括：由澄清腔室13❶申之熔融玻 璃124移除氣泡206之步驟，及將熔融玻璃124由澄清 腔至130送經第二導官136之入口 13<7之步驟，該第二 導管136在澄清腔室13〇與攪拌腔室134之間提供流體 連通（fluid communication) 〇 如第3圖與第4圖所圖示，進入入口 137之熔融玻璃 124包括.具有第一流量182之流體剖面18〇，該第一流 直182在比第二流量184之更低高度處在第二導管 内流動，該第二流量184在第二導管136内流動。如進 一步所圖不，該方法亦可包括：將第二導管136内之流 體剖面180重新導向之步驟，使得第一流量182在比第 二流量184之更高高度處在第二導管136内流動。 该方法亦包含將熔融玻璃124由第二導管136之出口 139送至攪拌腔室134中之步驟。熔融玻璃124接著在 攪拌腔室134中被攪拌。例如，可轉動軸14〇可如轉動 箭頭142所指而被轉動，以轉動混合元件138 (示意地 20 201242919 圖，F於第3圖中）。藉由攪拌腔室134的動作，可在將熔 融玻璃之流量由攪拌腔室送至成型容器以使玻璃物件成 型之前，將熔融玻璃124均質化。 將理解，攪拌腔室134係被設計以減少熔融玻璃124 中的化學變化，該等化學變化係源自熔化製程❶例如， 將批量材料熔化，及部分設備1〇2 (例如耐火材料）的 分解，為可造成熔融玻璃124中化學變化之來源的範 例希望達成授拌腔室134中熔融玻璃的最佳混合，以 使離開攪拌腔室至成型容器之熔融玻璃124的均質化最 佳化。最佳攪拌為玻璃均質化之間的平衡，該玻璃均質 化可藉由以下方式加強：增加攪拌元件138與攪拌腔室 134的壁之間的剪力。另一方面，增加剪力亦可增加搜 拌腔室134内的材料腐蝕，因此增加不希望的來自部分 攪拌腔室之分解的化學成分。 據信’如上述所論述的將流體剖面j8〇重新導向，可 導致改良玻璃均質化’而不增加混合元件138在攪拌腔 至134中的轉動速度。在進一步的範例中，將流體剖面 180重新導向可允許相同或經增加的均質化，而伴隨較 慢的混合元件之轉動速度；從而減少由剪力所造成的分 解，該剪力介於混合元件138與攪拌腔室134之壁之間。 建模結果指出：接近流體剖面底部進入攪拌腔室的熔 融玻璃124傾向位於較少被攪拌腔室j34混合之位置。 因為缺陷傾向落於沿著「污泥層」處，所以流體剖面之 底部位置相應於熔融玻璃124中最大程度的非同質性。 21 201242919 因此，當進入攪拌腔室134時，將位於流體剖面18〇之 第一流量182處之污泥層重新導向於較高高度處，可增 加離開攪拌腔室134之熔融玻璃124的整體同質性。 接著，返回第1圖，熔融玻璃124的均質混合可送經 第二導管146與傳送容器144，經過降流管148並進入 成型容器152之入口 15〇中。如第2圖所圖#，成型容 器可包含：等靜壓管，該等靜壓管係經設計以熔融下拉 出玻璃帶104,以接著用於處理玻璃板。當由更為均質

The batch material 1 〇 8 can be introduced by the batch transfer device U2, which is powered by the motor n4. The selectivity controller 116 can be configured to activate the motor 114 to introduce a desired amount of batch material 108 into the glass melter 1 6 as indicated by arrow 118. The detector 12 can be used to measure the height of the molten glass 124 (ievel) 122' within the standpipe (126) and communicate the measured information to the controller 116 via the communication line 128'. The melt down draw apparatus 1〇2 may also include a fining chamber 130 (e.g., a clarification tube) located below the glass melter 1〇6. The clarification chamber 130 is arranged to receive the glazed glass 124 by the glass dissolver 1〇6. For example, in one example, the smelting down apparatus 1 〇 2 includes a first conduit 132 that is configured to provide a path for the molten glass 124 to flow from the glass melter j 〇 6 to the clarification chamber 130 . The melt down draw apparatus 102 can further include a stir chamber 134 located downstream of the clarification chamber. The agitation chamber 134 is configured to receive the molten glass ι 24 from the clarification chamber 130. For example, the melt down device 102 can include a second conduit 136 that is configured to provide a path for the molten glass 124 to flow from the yielding chamber 130 to the mixing chamber 134. In one example, The agitation chamber ^ 134 can include a plurality of mixing elements 138 mounted to the rotatable shaft 140' for fine rotation about the rotatable shaft 14'', as indicated by the turning arrow 142. 12 201242919 As shown, a forming vessel 152 can be located downstream of the retrieval chamber 134, wherein the forming vessel ι5 is configured to receive the molten glass 124 from the dispensing chamber 134 and shape the glass article. For example, the melt down apparatus 102 can include a delivery vessel 144, such as a tank (b〇wl), located downstream of the agitation chamber 134. The transfer container 144 can be configured to receive the molten glass 124 from the agitation chamber 134. For example, the 'melt pull down device 102 can include a third conduit 146 that is disposed to provide a path for the molten glass 124 to flow from the agitation chamber I34 to the transfer vessel 144. As further illustrated, the 'melt pull down apparatus 1 〇 2 may also include: a downcomer 148 that is positioned to transport the molten glass 124 from the transfer vessel 144 to the inlet of the forming vessel 152 150 ' as indicated by arrow 154. A variety of shaped containers can be used in accordance with the present disclosure, depending on the particular application. For example, shaped containers can be used to provide glass articles having a wide range of settings for different optical applications. For example, a shaped container can be designed to provide a glass lens or other optical glass assembly. In only one dry case, the shaped container may comprise: a device for processing the glass ribbon. Such a molded container may include: a pull-down type (d〇wndraw), an up-draw type, a floating type (fi〇at), a molten type (fusi〇n), a roll-type (press rolling), a flow hole. Slotted draw or other shaped container for the production of glass articles. In one example, a shaped container can be designed to provide a glass ribbon that can be used in a variety of applications. For example, the glass ribbon provided by the molded container can be further processed to be incorporated into the following 13 201242919. Liquid crystal display, electrophoretic display, organic light emitting diode display, electrosonic display panel or other display or lighting application . In one non-limiting example, FIG. 2 illustrates an example shaped container 152 that can optionally include: isostatic tubes that are configured, for example, from molten glass Melt out the glass object. For example, Fig. 2 is a cross-sectional perspective view of the isostatic pressing tube for the example of the molten pull-down device 1〇2 along the line 2_2 in the i-th figure. As shown, the shaped container 152 includes a shaped wedge 156 that includes: a pair of downwardly sloping contoured surface portions of the contoured surface portions 158, 16 that are formed in the shaped wedge 156. Extend between the ends. The pair of downwardly inclined forming surface portions 158, 16 are merged in a downstream direction 162 to form a root portion 164. The drawing plane 166 extends through the root 164, wherein the glass ribbon can be pulled along the drawing plane 166 on the downstream square 162 as shown, and the drawing plane 166 can bisect the root 卩I64 'although the drawing plane 166 It can extend in other directions relative to the root 164. As illustrated in FIG. 4, the molten glass 124 in the first conduit 132 and the second conduit 136 includes a fluid profile 18〇 having a first flow rate 182 that is greater than the second flow rate. The lower temperature of 184 flows within the conduit, and the second flow 184 flows within the conduit. In one example, the first flow 182 can flow along the lower P-knife 132a 136a of the conduit and the second flow 184 can flow over the first flow 182. Thus, the first flow rate 182 can be between the second flow rate 184 and the lower portion 132a, 136a of the conduit. In a further example 14 201242919 A, the second flow 184 can flow within the conduit at a higher elevation than the first flow 182 and laterally offset from the first flow 182 rather than above the first flow 182. The melt down draw apparatus 102 can optionally include: a structure within the first conduit 32 and/or the second conduit 136 that is configured to twist the fluid profile 180 in the conduit such that the first flow 182 is within the conduit The second flow 184 has a higher altitude flow. For example, in one example, the first grip 184 can flow below the first flow 182 such that the second flow 184 can be between the first flow 182 and the lower portion i32a, 136a of the conduit. In a further example, the first flow rate i82 can flow at a higher elevation than the second flow rate 184 within the conduit and laterally offset from the second flow rate 184 rather than above the second flow rate 184. In one example, the structure can include a device located within the conduit to twist the fluid profile. For example, the device may include: a helical blade vane 170' which is configured to redirect the fluid section 180. As shown, the helical blade 17A can be non-rotatably secured to the first conduit 132+ (as illustrated in FIG. 1G) and/or the first conduit 136 (as illustrated in Figures 1 and 3). Show). As shown in Figures 4 and 7, if a helical blade 170 is provided, the helical blade 170 can be configured to reverse the fluid profile 18 of the molten glass 124 of the conduit 132, 136+. The spiral blade 17G may include a wide range of settings. As shown in Figures 4 and 7, the spiral blade 170 may comprise a smooth spiral arrangement to avoid dead fl〇w zones and to minimize the build-up of the pressure 15 201242919 in the conduit. The smoothing of the spiral arrangement further avoids ebbing or other disturbances in the flow of the glass as it is twisted. Thus, when twisting the fluid profile with the helical blade 170, the smoothing of the spiral arrangement allows for torsion of the fluid flow while minimizing disturbances in the fluid flow of the laminar flow. Further, the spiral blade 170 includes: a simple structure having a smooth arrangement. The simple structure having a smooth arrangement allows any air bubbles to pass through, and the bubbles may not be able to leave the molten glass passing through the duct. Although it is intuitively possible to remove the bubbles immediately by the redirecting means in the fluid path, it is surprising that allowing the glass bubbles to pass freely can, in fact, simplify the subsequent removal of glass bubbles in the molten glass. In fact, attempting to dissipate the bubbles with a redirecting device placed on the path of the molten glass can in fact lead to the accumulation or accumulation of bubbles which can complicate the subsequent removal of the bubbles prior to shaping the glass article. Thus, the simple geometry of the helical vanes 17〇 assists in the passage of any bubbles that cannot pass through the path of the molten glass. The helical nature of the blade may thus undesirably assist in the removal of any bubbles in the molten glass by: allowing the disturbance of the bubbles passing through the helical blade 170 to be minimized. As shown, the helical blade 170 can include an upstream end 1723 and a downstream end 172b that define a continuous helical segment therebetween. Although not shown, a plurality of segments can be stacked continuously in the catheter to produce a desired redirect of the fluid profile 180, depending on the particular application. As further illustrated in Fig. 7, the helical blade 17A can comprise two helical edges, the helical edges 1733, 17 complement 16 201242919 can assist the helical blade i 7 () with its spiral edge 171 / mounted on the guide s inside. In one example, the screw ground #3 173Ϊ>#' fits into the catheter, although the '(4) spin edge can be == mechanically attached to the catheter such that the helical blade (7) is non-rotatably worn in the catheter. As shown in the further step, the upstream end ma may comprise a downstream edge of the upstream edge (four) may comprise a downstream edge (four). The illustrated edge is substantially flat, but one or both edges may be And the ancient ° addition 'as shown in the 'edge' is generally straight, but the edge can be -. 'f curved shape, such as S shape (in a further example). People as shown in Figure 7 'in- In one example, the helical blade 170 may be in the shape of a shape which is produced by a clockwise rotation of the section axis (7) between the upstream edge 4a and the downstream edge IWb in the axial flow direction 19 (). In the following, the shape of the spiral > 17〇 can also be generated by: # 由 turning the section axis between the first edge and the second edge. The section axis 176 can be at the upstream end i72a and the downstream end "2b" Rotating at a wide range of angles. For example, the section car 176 can be twisted to twist the angle between the upstream end 172a and the downstream end 172b of the auger blade 170, the angle being between about 90 and about 360. 4, such as at about 90. to about 270., or at about 9 〇. to about 18 〇. As shown in Figure 7 As is apparent from Figures 5 and 6, in one example, the helical blade 170 can be twisted between the upstream end 172a and the downstream end 172b by an angle of about 180. A helical blade 17 having an upstream edge can also be installed. That is, the upstream edge has a wide range of angles a from the horizontal axis 192, and the horizontal axis 192 hangs 17 201242919 straight to the axial flow direction 190. For example, the upstream edge can be tilted from 〇 to 18 〇. The angle α, for example, relative to The horizontal axis 192 is from about 3 〇 to about 6 〇. As shown in Fig. s, the 'upstream edge 1743' is located from the 豕 174a at an angle of about 4 with respect to the horizontal axis 192. As shown, at the sixth In the figure, with a helical twist of 18 〇, the downstream edge 144b can also be at an angle β of about 45. As further illustrated in Figure 5, when viewed from the cross-section of the conduit and looking into the axial flow direction 190' Four quadrants j, π, and out are observed, wherein the upstream edge 174a extends diagonally between the quadrant and the quadrant. Figures 8 and 9 show the use of blades similar to those illustrated in Figure 7. Computer model of spiral blade 'where the blade is at the upstream end i72a and the downstream end 17 The angle between 2b is about (10). The angle is the shape produced by the clockwise rotation of the axial section to the central section axis 176. Figure 8 shows: The upstream edge of the horizontal axis 192 is mounted 174" computer model shows: when melting When the glass 124 flows downstream from the upstream position 200 at the upstream end 172 & of the spiral blade 17 流 through the spiral blade 17 to the downstream position 2 〇 2 at the downstream end 172b of the spiral blade, the first section of the fluid profile 18 〇 182 is reversed. As indicated by the dashed line, the first flow-rate 182 of the fluid profile is redirected to a higher height and is within quadrant η and quadrant III. Figure 9 is a view showing the result of mounting a spiral blade having an upstream edge 174a. The upstream edge 174a is located at about 45 with respect to the horizontal axis 192. At angle α. However, unlike Figure 5, the installation of the computer model provides an upstream edge 174a, which is diagonally shown in the quadrants π and quadrants, and the computer model shows that when the molten glass 12 4 is from 18 201242919 upstream end When the upstream position 210 at 17 a flows downstream through the spiral blade 17 to the downstream position 202 at the downstream end 172b, the first flow rate 182 of the fluid profile 18 is redirected. As shown, it is about 45. The angle a mounts the movable downstream position 202 such that the downstream position 202 is redirected to a higher height and generally along the vertical axis 204 and above the upstream position 200, the vertical axis 204 being perpendicular to the horizontal axis 192. As shown in the figure, the downstream position may be about 5% of the height of the overall height of the catheter. In a further example, the height may be higher or lower than 50% of the height of the catheter. As shown, the glass melter 1〇6, the clarification chamber 130, the agitation chamber 134, the transfer vessel 144, and the forming vessel ι52 are examples of glass melting positions. The glass melting positions can be along the molten down-draw apparatus 1〇2 Being placed in succession. The glass melter 106 is typically constructed of a refractory material, such as a refractory (ceramic) brick. The molten down-draw apparatus 1〇2 may further comprise: an assembly typically composed of platinum or a metal comprising platinum, such as platinum-ruthenium, platinum-ruthenium or a combination of platinum-ruthenium and platinum-ruthenium, However, such components may also include, for example, the following refractory metals: molybdenum, palladium, rhodium, iridium, titanium, ruthenium, osmium, hungry, alloys of zirconium with such metals and/or zirconium dioxide. The included components may include: _ or more of the following: a first guide f HZ, a clarification chamber 13 〇 (eg, a thinner tube), a second conduit 136, a standpipe 126, a stirring chamber to 134 (eg, agitation) The chamber), the mixing element 138 and the rotatable shaft 140, the third conduit 146, the transfer container 144 (e.g., the trough), the downcomer 148, the ηn, the crucible 150, and the spiral vane 170. The shaped container 152 is also constructed of a phoenix material' and is designed to form a glass|104. In the example of the advancement of 19 201242919, the forming container 152 may be constructed of other materials, which may not necessarily be refractory materials. For example, the forming vessel 152 can comprise 3. all metal or metal coatings, although other materials may be used in further examples. See the method of manufacturing a glass article. As illustrated in the figure, the method may include the step of melting the batch material in the glass melter 1〇6 to produce the molten glass 124. As illustrated in Figure 3, the molten surface 124 is then sent to the clarification chamber 130, for example, by the first conduit 132'. The method then includes the steps of removing the bubble 206 by the clarification chamber 13 from the molten glass 124, and the step of passing the molten glass 124 from the clarification chamber 130 to the inlet 13 <7 of the second guide 136, the second The conduit 136 provides fluid communication between the clarification chamber 13A and the agitation chamber 134. As illustrated in Figures 3 and 4, the molten glass 124 entering the inlet 137 includes a first flow rate 182. The fluid profile 18A, the first flow straight 182 flows within the second conduit at a lower elevation than the second flow 184, and the second flow 184 flows within the second conduit 136. As further illustrated, the method can also include the step of redirecting the fluid profile 180 in the second conduit 136 such that the first flow rate 182 flows within the second conduit 136 at a higher elevation than the second flow rate 184. . The method also includes the step of delivering molten glass 124 from the outlet 139 of the second conduit 136 to the agitation chamber 134. The molten glass 124 is then stirred in the agitation chamber 134. For example, the rotatable shaft 14A can be rotated as indicated by the turning arrow 142 to rotate the mixing element 138 (shown schematically at 2012 20124291, F in Figure 3). By the action of the stirring chamber 134, the molten glass 124 can be homogenized before the flow rate of the molten glass is sent from the stirring chamber to the molding container to shape the glass article. It will be appreciated that the agitation chamber 134 is designed to reduce chemical changes in the molten glass 124 that are derived from the melting process, for example, melting the batch material, and decomposition of some equipment 1 (e.g., refractory). An example of a source of chemical change in the molten glass 124 is desired to achieve optimal mixing of the molten glass in the mixing chamber 134 to optimize homogenization of the molten glass 124 exiting the agitating chamber to the forming vessel. The optimum agitation is the balance between the homogenization of the glass which can be enhanced by increasing the shear between the agitating element 138 and the wall of the agitating chamber 134. On the other hand, increasing the shear force can also increase the corrosion of the material in the search chamber 134, thereby increasing the undesirable chemical composition from the decomposition of the partially stirred chamber. It is believed that 'redirecting the fluid profile j8〇 as discussed above can result in improved glass homogenization' without increasing the rotational speed of the mixing element 138 in the agitation chamber 134. In a further example, redirecting the fluid profile 180 may allow for the same or increased homogenization, accompanied by a slower rotational speed of the mixing element; thereby reducing the decomposition caused by shear forces that are interposed between the mixing elements 138 is between the wall of the agitation chamber 134. The modeling results indicate that the molten glass 124 entering the agitating chamber near the bottom of the fluid profile tends to be less in a position where it is less mixed by the agitating chamber j34. Since the defect tends to fall along the "sludge layer", the bottom position of the fluid profile corresponds to the greatest degree of heterogeneity in the molten glass 124. 21 201242919 Thus, when entering the agitation chamber 134, redirecting the sludge layer at the first flow rate 182 of the fluid profile 18〇 to a higher elevation increases the overall homogeneity of the molten glass 124 exiting the agitation chamber 134. Sex. Next, returning to Fig. 1, the homogeneous mixing of the molten glass 124 can be passed through the second conduit 146 and the transfer vessel 144, through the downcomer 148 and into the inlet 15 of the forming vessel 152. As shown in Fig. 2, the forming container may comprise: isostatic tubes designed to melt down the glass ribbon 104 for subsequent processing of the glass sheet. When the glass ribbon 1〇4 is formed from a more homogeneous molten glass 124, glass sheets can be produced which have an increased flatness of the finished glass surface, and the glass sheets avoid the inclusion of precious metal particles. Precious metal particles can additionally be created by corrosion of the agitator blade and the walls of the agitating chamber with a less efficient mixing procedure. As illustrated in Figures 4 and 7, the re-directing of the glass mixture can be achieved by using a screw, a rotary vane, and a swirling fluid profile, and again, when the spiral blade 17 is twisted, the fluid profile is reversed. At 180 o'clock, the helical leaf: 17 turns can remain non-rotatably fixed relative to the second conduit 136. Experimental evidence shows that enhanced mixing can be achieved by redirecting the fluid profile 18() at the first conduit 132 or at the second conduit (3). Figure 1 illustrates another example device trace. In the other example device 1〇2, the fluid profile is redirected in stem _ ^ ^ ^ ^ ^ , guide s 132. In this example, the '5" method includes the initial step of melting the batch material in a glass melter to produce a molten glass. The molten glass is then passed through an inlet 208' of the first conduit 132. The first conduit 132 provides fluid communication between the glass melter 1〇6 22 201242919 and the me/month chamber to 130. As shown, entering the inlet molten glass 124 includes a fluid profile X having a first flow 4 182. The first amount 182 is flowing within the first conduit 132 at a lower elevation than the second flow 184. - Flow inside the conduit 132. The method then includes the step of redirecting the fluid profile within the first conduit 132, </ RTI> {# θ at the first flow: !: 182 flowing within the first conduit 132 at a higher elevation than the second flow ι 84. The fluid profile in the first conduit 132 can be redirected by, for example, the aforementioned helical blade 17G. In an example, the helical blade 170 can be located outside of an electrical flange ((4)) 212 that is designed to provide an electronic heating circuit that is electrically convex. The provision of impedance heating between the rims 212 via the first conduit 132 thus 'places the helical vanes 17G at least partially in the glass melter m' may avoid interference with the impedance addition circuitry. The helical blade 170 within the first guide 132 also provides additional structural stability to the conduit 132, which can be easily deformed over time. This embodiment may have the additional benefit of increasing the rate of dissolution of the refiner to the flint by: reducing the saturation of the refractory chemical composition in the glass surrounding the refractory chemical composition. The method is then carried out by feeding the molten glass from the outlet 21 of the first conduit 132 to the clarification chamber 13 〇 + . The bubbles 2〇6 are then removed by the molten glass 124 in the clarification chamber 130. Then: the molten glass is fed to the mixing chamber 134. As shown, when the first flow of material M2 enters the agitating chamber 134, the first flow of material 182 is still 23 201242919 which may be located above the second conduit 136. Therefore, it is possible to increase the homogeneity of the molten glass and increase the quality of the glass article. As noted above, increased surface flatness can be observed in glass articles (e.g., glass sheets) by redirecting the fluid profile. It is also possible to reduce the month b; the agitation speed of the mixing element 138 in the agitating chamber 134 to provide less corrosion and thus provide more homogenization within the agitation chamber. Still further, increasing the mixing efficiency may allow for a reduction in the size of the agitation chamber 134, which significantly reduces the cost of manufacturing the agitation chamber 134, which is typically fabricated from a precious metal. It will be apparent to those skilled in the <Desc/Clms Page number> Thus, it is intended that the present invention cover the modifications and variations of the invention, and the modifications and variations thereof are within the scope of the appended claims and the scope of the appended claims.
