Inventor: ATWOOD MARK T
IPC: C02F5/08
Filed: 1986-11-21
Abstract: A method of removing scale from the surfaces of a fluid treatment apparatus comprises directing a base solution and an acid solution through the fluid treatment apparatus. The fluid treatment apparatus cleaned by the method of the present invention may be a vertical tube wet oxidation treatment apparatus in which an aqueous slurry of organic materials is oxidized in a tube which extends deep into the surface of the earth. Water rinses may be performed between the steps of circulating the aqueous base solution, circulating the aqueous acid solution, and operating the fluid treatment apparatus. The water used for separating the sequential steps is preferably buffered water. The aqueous acid solution is preferably a mineral acid and most preferably nitric acid. The aqueous base solution is preferably potassium hydroxide or sodium hydroxide. The method also contemplates a sectional wash of the apparatus by directing a base or acid solution partially into the apparatus.

Abstract: In a circular loom, displacement means engage on the inner partial heald (7) of a partial heald pair (6, 7) after each shedding motion in order to bring about the instantaneous lateral relative counter-displacement of the partial healds for the reciprocal displacement of the leno thread (51), extending lengthwise to the ground thread (50), two neighboring warp threads (50, 51), for the production of a leno fabric (6, 7). Furthermore, the warp threads of one partial heald of a partial heald pair are guided freely by thread guide means (24) to bring about the shedding, and, on the other partial heald, to bring about a side change.

Abstract: Elements for making butt splices in optical fibers are simplified when formed of a deformable material and formed to define three surfaces (18,23,30) for contacting the fibers to be spliced. The surfaces are formed between two legs (20,21) of an element such that when the legs are closed onto the fibers the surfaces center the fibers and afford a resilient spring compression reserve force on the aligned fibers to maintain them in contact and the fibers are depressed into the surfaces slightly to center the fiber cores. Should one fiber be larger than another, the surfaces will deform sufficiently to clamp onto both fiber ends and be deformed even by the smallest of the two fibers. Thus, the splice element 11 will center the cores of the optical fibers such that in aligned position 90% or better of the surfaces of the core portions be aligned.

Abstract: In the embodiment, the entire cylindrical surface of a cylindrical object such as a cigarette is optically inspected by first inspecting at least 180 DEG  of the circumference of a first side of the surface, and then inspecting at least 180 DEG  of the circumference of the other side. Each of the inspection stations illuminates more than 180 DEG  of the circumference and images the surface from two angularly spaced directions to ensure that at least 180 DEG  of the circumference is seen at each station. Any object having a defective image is automatically rejected from the apparatus, and the images and other statistical information regarding the performance of the system are displayed by the system. The images are formed in such a way as to greatly increase the speed at which the inspection system operates so that it an keep up with the very high rates at which objects such as cigarettes are made in modern machinery (e.g., approximately 10,000 cigarettes per minute). The images are analyzed using techniques which make possible the detection of very small defects and also compensate for possible nonuniform illumination of the objects in the circumferential direction. In another embodiment, inspection of completed cigaretes is accomplished by the cigarettes travelling on a rolling drum 1 pas a single stationary rolling block 12 with perferably two cameras 5,14 connected to a vision system. The first camera views the cigarette before the rolling block, the cigarette is then rolled approximately 180 DEG  and then the second camera views the previousl hidden portion of the cigarette. Cigarettes are accepted or rejected based on a comparison of the viewed cigarettes to a predetermined set of characteristics. <IMAGE>

Abstract: The present invention is directed to a method for making fused silica glass. A liquid, preferably halide-free, silicon-containing compound capable of being converted by thermal oxidative decomposition to SiO2 is provided and introduced directly into the flame of a combustion burner, thereby forming finely divided amorphous soot. The amorphous soot is deposited on a receptor surface where, either substantially simultaneously with or subsequently to its deposition, the soot is consolidated into a body of fused silica glass. The invention further relates to an apparatus for forming fused silica from liquid, preferably halide-free, silicon-containing reactants which includes: a combustion burner which, in operation, generates a flame; an injector for supplying a liquid silicon-containing compound to the flame to convert the compound by thermal oxidative decomposition to a finely divided amorphous soot; and a receptor surface on which the soot is deposited.

Abstract: A painting wagon carries a plurality of components to be painted through a painting facility. The wagon includes a component supporting assembly having a plurality of opposed pairs of component mounting pins fixed thereto. The component supporting assembly is supported by a base structure having wheels which permit the painting wagon to be translated. The component supporting assembly may be selectively adjusted between a contracted configuration in which each of the pairs of opposed mounting pins, and thus the components mounted thereon, are oriented in contracted proximity to one another, so as to minimize the overall size of the wagon with the components mounted thereon to accommodate given dimensional limitations of the painting facility and an expanded configuration in which the pairs of opposed mounting pins, and thus the components mounted thereon, are oriented so as to be expanded apart from one another so that individual components may be mounted and dismounted onto the component mounting pins with reduced danger of bumping an adjacently mounted component and thus damaging the surface finish of the components.
