Tubular articles

The removal of volatile components during processing. The gate used in molding annular or tubular articles that forms a solid web across the opening of the part. 

The flat knitting machine was fitted with sinkers, which controlled stitches in order to knit single-jersey tubular articles such as gloves, socks, and berets. 

The process is versatile with low capital investment. In the electrostatic spraying process, the particles released from the spray gun are electrostatically charged and propelled at low velocity by air or revolving spray head. Too much air pressure is to be avoided. This procedure produces a good wrap around without the need to positioning the workpiece. The process is suitable for tubular articles. 

This problem indicates the considerations that enter into the design of a tubular reactor for an endothermic reaction. The necessity of supplying thermal energy to the reactor contents at an elevated temperature implies that the heat transfer considerations will be particularly important in determining the longitudinal temperature profile of the reacting fluid. This problem is based on an article by Fair and Rase (1). 

In the following section, we will focus on markers and methods for measuring the GFR because data for dynamic and continuous renal function measurements are available. In doing so, we acknowledge the importance of tubular secretion and fixation markers in the overall evaluation of renal status, and the reader is referred to some articles covering these subjects [174,176-182]. 

Three broad categories define the analytical columns used in pHPLC Open tubular, semi-packed, and packed. Each of these three columns types is discussed briefly while making reference to the extensive review articles that cover each area. 

Drain. Tiles belong to the coarsest class of earthenware, and areaf various shapes sometimes curved over a mould, and sometimes formod by forcing the material through a machine by mechanical means. Other articles, likewise, come under this denomination of wares in their manufacture, such as chimney-pots, tubular pipes for water or drains, and which sometimes require the assistance of the lathe to complete their formation. 

Extrusion blow molding. In extrusion blow molding, a parison or tubular profile is extruded and inflated into a cavity with a specified geometry. The blown article is held inside the cavity until it is sufficiently cool. Figure 3.56 [25] presents a schematic of the... 

De Deken and his colleagues197 have studied the nature of the carbon deposited on a commercial CCE catalyst (12 wt% Ni on a-Al203) and have concluded that it has diffused into the bulk of the nickel and that some of it is present as carbide. A more applied article from the same group198 presents intrinsic kinetic data from a tubular reactor in the temperature range 823-953K. 

The potential applications of BIONELLE in injection-molded articles (such as cutlery, brushes, etc.), tubular films (composting bag, shopping bag), flexible packaging, food tray, cosmetic bottles, and beverage bottles have been projected. In some of these applications, there is a need to improve the performance of existing grades. 

Abstract. In article approaches to optimization of HHP operation as heat machine are planned. Optimization is directed on achievement of the maximal efficiencies, cold-productivities or levels of temperatures. Optimization of weight and the sizes of tubular sorbers are possible. The question of the coordination of a heat emission in hydride beds and heat exchangers is especially important. To increase efficiency of HHP it is possible, both by a choice of the best hydrides, and by optimum control in regime parameters of HHP. The mathematical modelling spent both a method enumeration of possibilities, and a regression procedure analysis, testifies to extreme behaviour of regime parameters of HHP. 

In 1983, Godec and Gleich reviewed all published results of treatment of intractable hematuria with formalin. Dilutions of 1-10% formalin (containing 0.37-3.7% formaldehyde) were used the most commonly used concentration of formalin was 10%. The authors concluded that formalin was probably the most effective tool for controlling massive hematuria, but also probably the most dangerous. The review covered 23 articles and 118 patients in 104 cases, treatment was successful. However, in only 10 reports had the treatment been used without serious adverse effects the other 13 articles listed four deaths and many serious local and systemic complications. The complication rate increased when the formalin concentration was higher, but the contact time and the volume instilled did not influence the occurrence of adverse effects. The most frequent local complications were reflux and hydronephrosis. Fibrosis of the bladder with reduced capacity was the usual clinical outcome. A systemic effect was tubular necrosis with anuria, with two deaths. Another complication was ureteric obstruction, which was not related to ureteric fibrosis or bladder wall fibrosis obstructing the intramural ureter in two cases the obstruction appeared to be due to retroperitoneal fibrosis (SEDA-11, 476) (4). 

The injection system in a GC analysis provides a means of introducing the sample onto the column. This is normally a simple injector design when packed columns are used. Capillary or open tubular columns require, however, more sophisticated design than do packed columns, because of their very low capacities and small internal diameters. A number of different injector designs have been recently developed. Unfortunately, no universal injector has so far been commercially available to handle all sample types. This article will discuss various approaches to sample injection.

The nonlinearity of chemical processes received considerable attention in the chemical engineering literature. A large number of articles deal with stand-alone chemical reactors, as for example continuously stirred tank reactor (CSTR), tubular reactor with axial dispersion, and packed-bed reactor. The steady state and dynamic behaviour of these systems includes state multiplicity, isolated solutions, instability, sustained oscillations, and exotic phenomena as strange attractors and chaos. In all cases, the main source of nonlinearity is the positive feedback due to the recycle of heat, coupled with the dependence of the reaction rate versus temperature. 

Zeolite X was also examined for the decomposition of polyethylene in a series of articles by Ayame and co-workers.Using both a batch reactor and a fixed bed tubular flow reactor, the rate of conversion of polyethylene was enhanced in the presence of CaX and NaX. Deactivation was observed in the flow studies, as the rate of formation of gaseous products decreased by a factor of three after 2.5 hours time on stream when the reaction was carried out at 750 K with 4.0 g of catalyst and a polyethylene flow rate of 7.23 x 10 g min . When a CaX catalyst was used, C4 species were observed in the highest yield. In the batch reaction, the yield of iso-C4 species was increased dramatically compared with thermal degradation, as thermal degradation afforded no iso-C4.
