Spinning company

Company (80). Rayon pretreated with hydrogen peroxide initiated grafting of styrene from an emulsion as reported by Toyo Spinning Company (81). 

The Houldsworth family had founded cotton-spinning companies in Glasgow and Manchester, and the Glasgow branch established the Anderston Foundry. Henry Jr became a partner sometime in the 1820s in the Manchester... 

DoreTex is a yam-spinning company that focuses on high-end yams. While 60% of the company s output is synthetic, the company s core focus is cotton. This is both because the DoreTex production technology is based on the system used for cotton and because the natural fibre, along with linen, hemp, silk, wool and cashmere, is what ensmes the company s privileged relationship with the fashion industry. Consequently, the application of the decision-making process was focussed on the cotton division. 

The second ceUulosic fiber process to be commercialized was invented by L. H. Despeissis (4) in 1890 and involved the direct dissolution of cotton fiber in ammoniacal copper oxide Uquor. This solvent had been developed by M. E. Schweizer in 1857 (5). The cuprammonium solution of ceUulose was spun into water, with dilute sulfuric acid being used to neutralize the ammonia and precipitate the ceUulose fibers. H. Pauly and co-workers (6) improved on the Despeissis patent, and a German company, Vereinigte Glanstoff Eabriken, was formed to exploit the technology. In 1901, Dr. Thiele at J. P. Bemberg developed an improved stretch-spinning system, the descendants of which survive today. 

A similar method of test was used at the International Nickel Company s Corrosion Laboratory at North Carolina. The specimen discs are mounted on insulated vertical spindles and submerged in sea-water, which is supplied continuously to the tank in which the specimens are immersed. The maximum peripheral speed of the spinning disc is about 760cms , and the characteristic pattern of attack is shown in Fig. 19.3a. Studies of variation of depth of attack with velocity indicate that at low velocities (up to about 450 cm s ) alloys such as Admiralty brass, Cu-lONi and cupro-nickel alloys containing iron maintain their protective film with a consequent small and similar depth of attack for the diflferent alloys. At higher velocities the rate increases due to breakdown of the film. 

Farnesol was obtained from Fluka AG (Buchs, CH9470, Switzerland) as a mixture of 65% (E), (E)- and 35% (Z), (E)- isomers. It is also available from the Aldrich Chemical Company, Inc. This procedure works equally well with pure (E), (F)-famesol, which may be obtained from the above mixture by careful distillation, at reduced pressure, through a Nester-Faust Teflon spinning-band column. 

Pure (A)-1 -chloropropene was obtained by careful distillation of a mixture of (E)- and ( )-l -chloropropene (available from Columbia Organic Chemicals Company Inc.) using a Nester-Faust Teflon annular spinning band column [(Z)-l-chloropropene has b.p. 33° (A)-l-chloropropene has b.p. 37°]. Small quantities of powdered sodium bicarbonate and hydroquinone (1,4-benzenediol) placed in the distillation flask inhibit acid-catalyzed isomerization and polymerization. Gas chromatographic analysis of the material used in these experiments on a 4-m., 15% l,2,3-tris(2-cyanoethoxy)propane (TCEP) on Chromosorb P column, operated at room temperature, typically indicated that it had isomeric purity >99.9%. (A)- 1-Chloropropene is stable for several months at room temperature, but it should be stored in a cool place. 

Fiber-containing cement was initially developed as a high-strength material that could be used to line a borehole [1789]. Several relatively simple and cheap spin-off applications of fiber cement were identified, such as the use of fiber cement in cement plugs for borehole stabilization and as a lost circulation material. Several companies are already applying or offering fiber cement for these purposes in the field, in both organic fibers and metal fibers [372,1077, 1682-1684].

In 1999 a new type of annular chromatograph was presented by Prior Separation Technology GmbH, a spin-off company of Prior Technology GmbH. At the same time the selling of the machine under the brand name of P-CAC started. 

Many companies are investor-driven and, thus, have an intense dedication to development and success. But can a company with one or two products compete It appears it can. However, often the process requires merger or acquisition by larger firms fo succeed. Some companies sfarf ouf as "spin offs" of academic research, ofhers license a producf being developed by "big pharma," and ofhers sfarf as marketing or generic firms fhaf grow from fheir own success.
