On j November, the zd Platoon began a 102-day haze to cover an exposed stretch of Highway 64, as well as several supply installations, in the right sector of IV Corps. Just as in the case of Highway 6j south of Bologna, before the haze daytime traffic on the road always drew fire. Afterward, the amount of enemy fire noticeably decreased, bridges were built and strengthened without interruption, and traffic passed with little interference. 

The degree to which arrangements need to be made to ensure the safe evacuation of members of the public from a building depends upon the level of risk. In some cases it will be considered to be reasonable to simply display some fire notices within some premises where there is limited public access. At the other end of the scale, for large premises or when large numbers of people are present, additional arrangements, such as public address systems and fire marshals, may be needed.

The fire was more serious than it would normally have been because the inventory in the plant, about 70 tons, was about twice the usual amount. Some of the overheads from a reactor were collected in a slops drum and recycled. The inventory in the drum was usually small. At about 9 a.m. on the day of the fire, the recycle pump failed. As a result, the level in the drum rose, and the level in the reactor fell. The operator noticed the fall in the reactor level (but not the rise in the drum level) and recycled product to maintain the level. At 8 p.m. the supervisor noticed that the high-level alarm on the slops drum was lit he found that the recycle pump had failed, and he changed over to the spare it leaked 25 minutes later. Section 3.3.1 describes another occasion when operators failed to notice unusual readings for 11 hours. 

As we mentioned above, however, linearly inseparable problems such as the XOR-problem can be solved by adding one or more hidden layers to the perceptron. Figure 10.9, for example, shows a solution to the XOR-problem using a perceptron that has one hidden layer added to it. The numbers appearing by the links are the values of the synaptic weights. The numbers inside the circles (which represent the hidden and output neurons) are the required thresholds r. Notice that the hidden neuron takes no direct input but acts as just another input to the output neuron. Notice also that since the hidden neuron s threshold is set at r = 1.5, it does not fire unless both inputs are equal to 1. Table 10.3 summarizes the perceptron s output. 

Other preparations and isolations. If damp methylenedi(nitroformamide) is allowed to stand for several days, the odor of formic acid is noticed, and MEDINA can be isolated from the residue (Ref 11, p 14). The details of scale-up to 150 lb batches, including exp details and flow sheets, and further scale-up with the aim of prodn of 1000 lbs are given. The report describes a fume-off and fire which occurred during the S3rd run. The cause was attributed to a stuck valve which allowed nitric acid to build up in the reactor (Ref 13, p 57). In Ref 16, p 73 there are cost analysis data for pilot plant and large scale prodn, flow sheet for a proposed coml plant, and material balances. The action of acet anhydr on N,Nf-bis(hydroxy-methyl)MEDlNA regenerates MEDINA (Ref 6) the diNa salt of N. N trinitrotrimethylene-diamine, on warming with me ale, ppts the Na salt of MEDINA... 

Arulanantham and Lees (1981) have studied pressure vessel failures in process plants such as olefins plants. They define failure as a condition in which a crack, leak or other defect has developed in the equipment to the extent that repair or replacement is required, a definition which includes some of the potentially dangerous as well as all catastrophic failures. In olefins plants fired heaters have failure rates of about 0.4 failures/year, while process pressure vessels have 0.0025 failures/year and heat exchangers 0.0015 failures/year. It is noticed that fired heaters are much unsafer than process pressure vessels, which are a little unsafer than heat exchangers. 

It was noticed that the order of process items in the layout spacing recommendations is almost identical. The furnaces and fired heaters are on the top of the list (see Table 18). The next group is formed by compressors and high hazard reactors. Air coolers, ordinary reactors and high hazard pumps appear next. After that come towers, process drums, heat exchangers and pumps. The last and safest group is formed of equipment handling nonflammable and nontoxic materials. 

A patented water injection system has been devised for extinguishing oil and gas well fires in case of a blowout. The "Blowout Suppression System" (BOSS) consist of finely atomized water injected to the fluid stream of a gas and oil mixture before it exits a release point. The added water lowers the flame temperature and flame velocities thereby reducing the flame stability. In the case where the flame cannot be completely dissipated, the fire intensity is noticeably deceased, preserving structural integrity and allowing manual intervention activities. A precaution in the use of such a device is that, if a gas release fire is suppressed but the flow is not immediately isolated, a gas cloud may develop and exploded that would be more destructive that the pre-existing fire condition.
