At present there are two practical approaches in the design of casting equipment and procedures for a propellant with unfamiliar characteristics. One can measure directly height of casting vs. time in a long cylindrical experimental casting, or the solvent viscosity may be determined as a...

Centrifugal casting allows for greater control of the distribution of phases, by controlling the time of separation. The two types of centrifugal casting equipment are shown in Fig. 9. For radial centrifuges (Fig. 9a), the sample is placed at a... 

At the end of the article I ve included some info on a mail order firm that specializes in supplying furnaces and casting equipment to the home metal caster. A catalog of casting books, sand casting kits and supplies is also available for 2.50 from Caldwell Industries, Box 591, Luling, Texas 78648. 

Polymer concretes can be mass produced, taking advantage of short curing times. With special processing techniques and molds it is also possible to cast equipment such as wash basins and bath tubs, plain or with a marble or onyx effect, slabs with many different surface effects, and even marbles with two or more colors. 

Introduction of microgravure and slot die coating heads on tape casting equipment in Japan to produce precision thickness in thin tape-cast materials. 

Tape casting equipment capable of manufacturing 5-micron tapes continuously for use in multilayered ceramic capacitors introduced to the marketplace in Japan and the U.S. 

The optimized slip is now ready to be moved to the casting equipment for forming the tape-cast product. The tape casting process is discussed in Chapter 4. 

As illustrated in Fig. 6.38, the key component of the tape casting equipment is the doctor blade assembly. It consists of an adjustable doctor blade mounted in a frame with a reservoir to hold the slurry (or slip) before it is metered out under the blade to form the thin layer of slurry on the carrier surface. The flow behavior of the slurry during the casting of the tape has been analyzed theoretically to estimate the influence of the casting parameters on the thickness of the tape (47).

A decade after Dr. Hassler s efforts, Sidney Loeb and Srinivasa Sourirajan at UCLA attempted an approach to osmosis and reverse osmosis that differed from that of Dr. Hassler. Iheir approach consisted of pressurizing a solution directly against a flat, plastic film. Their work led to the development of the first asymmetric cellulose acetate membrane in 1960 (see Chapter 4.2.1). This membrane made RO a commercial viability due to the significantly improved flux, which was 10 times that of other known membrane materials at the time (such as Reid and Breton s membranes). These membranes were first cast by hand as flat sheets. Continued development in this area led to casting of tubular membranes. Figure 1.3 is a schematic of the tubular casting equipment used by Loeb and Sourirajan. Figure 1.4 shows the capped, in-floor immersion well that was used by Loeb and students and is still located in Boelter Hall at UCLA.
