Spinner

In Europe, 1. G. Earbenindustrie decided to develop nylon-6 that had been synthesized from S-caprolactam using an aminocaproic acid catalyst (1) and commercially introduced as Pedon L in 1940 (11,12). 1. G. Earbenindustrie had evaluated over 3000 polyamide constituents without finding an improvement over nylon-6 and nylon-6,6 (13). In Italy, Societa Rhodiaceta started making nylon-6,6 in 1939. In the United Kingdom, ICl and Courtaulds formed British Nylon Spinners in 1940 and started to manufacture nylon-6,6 in 1941. [Pg.246]

The Sturtevant air separator Stuiicvant Inc.) incorporates a hydrauhc mechanism to adjust the width of the ring baffle over the spinner blades, which allows adjusting the separation cui ve within limits, at some cost in production rate. For example, the residue on 74- Im screen can be varied from 1 to 20 percent, with a production rate shown in Table 20-20 for cement rock. [Pg.1857]

The Wilhams ring-roller mill Williams Patent Crusher Pulverizer Co.) is an air-swept mill with integral classifier of the rotating-blade type (the Spinner air classifier) or a double-cone type. The fluid-bed roller mill system has jets to introduce hot air into the bed of coal in the mill to diy it. [Pg.1863]

Because the laser beam is focused on the sample surface the laser power is dissipated in a very smaU area which may cause sample heating if the sample is absorbing and may cause break-down if the sample is susceptible to photodecomposition. This problem sometimes may be avoided simply by using the minimum laser power needed to observe the spectrum. If that fails, the sample can be mounted on a motor shaft and spun so that the power is dissipated over a larger area. Spinners must be adjusted carefully to avoid defocusing the laser or shifting the focal spot off the optic axis of the monochromator system. [Pg.435]

Aircraft radomes, ducting, spinners and other parts are often prepared from polyester resins in conjunction with glass cloth or mat. The principal virtue here is the high strength/weight ratio possible, particularly when glass cloth is used. Land, sea and air transport applications account for almost half the polyester resin produced. [Pg.707]

The first tank was cleaned without incident. By the time the contractors started on the second tank, a new foreman was in charge. To soften the deposits, he disconnected the steam coil, blew live steam into the tank, and then sprayed kerosene onto the walls, section by section, using a spinner mounted on a tripod. The report does not make it clear whether or not the kerosene was heated. While men were moving the tripod, a fire started in the tank, followed by an explosion. Three men were icilled. one by the fire and tw o by falling bits of the external concrete cladding. [Pg.349]
