M47 loo-pound bomb with an incendiary filling was satisfactory, but it was late in 1942 before a successful filling could be produced in quantity. Quantity production of toxics was just beginning, and not even token shipments to the European theater were authorized until January 1943. Defensive equipment and service supplies were no more available to the air forces than they were to the ground and service forces, and all stockages in and destined for the European theater were subject to the demands of the North African campaigns. Existing demands on the British supply system had reached monumental proportions, but the British were in a position to be of some assistance to the chemical preparedness of the United States forces. 

While the total quantity of British chemical warfare materials furnished the United States Forces was small, and while only token deliveries were made in 1942, awareness of British capability and British reserves was nearly the only reassuring gleam in the dark chemical supply picture from July 1942 to July 1943. The entire gas warfare retaliatory potential depended on British resources for most of that period. CWS ETO officers measured the British contribution as much or more in terms of their willingness to co-operate and their readiness to provide technical and operating experience data as they did in their provision of supplies under reverse lend-lease. ... 

Other weapons and ammunition furnished by the CWS ETO to the combat forces included the flame thrower, smoke pots, and smoke grenades. The CWS ETO had acquired a sufficient supply of the portable flame throwers, and chemical units had mixed a substantial quantity of thickened fuel. No American tank-mounted flame thrower was available, but fuel had been mixed for use in British models on loan in limited numbers to the United States forces. Soon after the invasion, St. John reported critical shortages of both portable and mechanized flame throwers and of fuels as well as of mortars and mortar parts, but subsequent experience did not warrant the critical designation since flame throwers were not popular in Europe. ... 

The incendiary bomb had the distinction of being one of the most effective munitions employed strategically by United States forces in World War II. Ranging from a compact 4-pound, metallic model to an oil-filled 500-pounder, these bombs, developed and procured by the CWS and employed by the Army Air Forces, wrought almost im-paralleled destruction. Tlie fire bomb, the tactical corollary of the incendiary, proved effective when dropped by fighter-bomber aircraft on a variety of targets in the forward areas. 

At this point in time, the total sulfur content of crudes was not taken into consideration, since most of them were produced and refined in the United-States and contained less than 1%, and only the gasoline coming from corrosive crudes needed sweetening (elimination of thiols) for them to meet the specifications then in force. Today all crudes containing more than one per cent sulfur are said to be corrosive . 

United States Caustic Soda Production. In 1987 U.S. production of caustic soda increased to 10.4 million tons (fig. 1), more than 10% over that of the previous year, furthermore, 1988 production was up another 6.7% to 11.1 million tons. The demand for caustic soda has been very strong in recent years as evidenced by both increased U.S. consumption and a strong export demand. In 1987 the United States exported 1.5 million tons, 14.5% of the total caustic soda production (6), representing a 25.5% increase over exports in 1986. Then, in 1988, caustic soda exports grew by another 4.1%. A weak doUar helped boost the 1987 exports. Growth slowed in 1988, however, as a result of an industry (and world) wide caustic soda shortage, which was caused by lower U.S. chlorine consumption and forced allocations. Because industries switched from caustic to soda ash where possible, the lower 1988 export growth was not indicative of caustic soda s export potential. 

Caustic Soda to Chlorine Balance. In 1988, the ratio of U.S. caustic soda to chlorine consumption was 0.96 1 (see Fig. 39). Since 1968 this ratio has ranged from alow of 0.88 1 (1978 and 1981) to a high of 0.98 1 (1969). No single factor can explain these variations, since caustic soda and chlorine, with few exceptions, have different markets and are therefore not driven by the same economic forces. This ratio is expected to trend upward over the next five years, however, since caustic soda consumption in the United States is forecasted to grow somewhat faster than chlorine consumption. It is expected that this ratio will remain within the range experienced in 1970—1990. Because caustic soda is co-produced with chlorine at a theoretical ratio of 1.1 1, a U.S. consumption ratio below that level results in excess avaHabihty of caustic soda. This material is typically shipped offshore to fill a significant export demand, and in 1988, for example, net U.S. exports of caustic soda amounted to 7.1% of production. 

In most of the rest of the world the olefins industry was originally based on naphtha feedstocks. Naphtha is the dominant olefins feedstock in Europe and Asia. In the middle 1980s several large olefins complexes were budt outside of the United States based on gas Hquids feedstocks, most notable in western Canada, Saudi Arabia, and Scotiand. In each case the driving force was the production of natural gas, perhaps associated with cmde oil production, which was in excess of energy demands. 

The amount of Hquid crystals produced each year for appHcations is several tens of tons, with the vast majority designed specifically for display appHcations. Several of the largest producers of commercial Hquid crystals are E. Merck, Hoffmann-LaRoche Inc., and Chisso. E. M. Chemicals (Hawthorne, New York) is the distributor for E. Merck in the United States and Chisso America Inc. has an office in New York. Hoffmann-LaRoche and Di Nippon Inc. have joined forces to form a new company, Rodic.

Issuance of a United States patent transforms a patent appHcant into a patentee, and new concerns may arise relevant to management. For example, the patent should be reviewed to determine formal and substantive correctness. An audit should be taken regularly to determine whether there is a continuing justification to pay the maintenance fees required to keep the patent in force during its effective period. The patentee or patent assignee may have to address concerns of patent infringement or patent vaHdity. 

Naphthalene (qv) from coal tar continued to be the feedstock of choice ia both the United States and Germany until the late 1950s, when a shortage of naphthalene coupled with the availabihty of xylenes from a burgeoning petrochemical industry forced many companies to use o-xylene [95-47-6] (8). Air oxidation of 90% pure o-xylene to phthaUc anhydride was commercialized ia 1946 (9,10). An advantage of o-xylene is the theoretical yield to phthaUc anhydride of 1.395 kg/kg. With naphthalene, two of the ten carbon atoms are lost to carbon oxide formation and at most a 1.157-kg/kg yield is possible. Although both are suitable feedstocks, o-xylene is overwhelmingly favored. Coal-tar naphthalene is used ia some cases, eg, where it is readily available from coke operations ia steel mills (see Steel). Naphthalene can be produced by hydrodealkylation of substituted naphthalenes from refinery operations (8), but no refinery-produced napthalene is used as feedstock. Alkyl naphthalenes can be converted directiy to phthaUc anhydride, but at low yields (11,12). 

European siting considerations are somewhat different than those in the United States. Germany, the Netherlands, France, and Italy were traditionally the favored locations for European CPI industry plants because of their proximity to the markets, cheap energy, and presence of a skilled labor force. 

In 1993, the United States medical device industry employed 282,000 people, averaging a growth rate of about 4% since 1975. Research and development spending in this industry outpaced that in virtually every other industry. Over 7% of sales were spent on research and development in 1993, amounting to a Httle less than 3 bHHon. This rate reflects both the rapid rate of innovation and short product life-cycle. Medical devices become obsolete far more rapidly than pharmaceuticals (qv), forcing companies continuously to be innovative. 

More often than not, however, the demand for post-consumer materials has failed to keep pace with this boom in collection. In many regions of the United States and elsewhere, the supply of recyclable materials is so great that cities have been forced to either store the materials or curtail the number of items collected. Many principal cities worldwide have reported occasions when source-separated materials were actually sent to dumps or incinerators rather than being recycled (4).
