	Continuous production of phenol-formaldehyde resin and laminates produced therefrom - Patent 4413113
		For example, in the production of conventional thermoset plastics laminates, it is customary to produce the phenol-formaldehyde resin used to impregnate the core sheets in a batch process, employing aqueous solutions of formaldehyde (e.g.
		As a major technical problem to be overcome in the production of these resins is the control of the exotherm, one of the principal concerns of the originators of the various forms of equipment known has been to provide a reactor wherein the heat arising during the condensation may be effectively and controllably dissipated.
		The tube which was continuous and provided with a belled junction between the first and second section, was coiled into a spiral having a diameter of about 0.75 m and it was positioned in a stirred cylindrical tank containing water which was maintained at 100.degree.

	Crop rotation - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-23)
		A crop that leaches the soil of one kind of nutrient is followed during the next growing season by a dissimilar crop that returns that nutrient to the soil or draws a different ratio of nutrients, for example, rice followed by cotton.
		By crop rotation farmers can keep their fields under continuous production, without the need to let them lie fallow, and reducing the need for artificial fertilizers, both of which can be expensive.
		From the end of the Middle Ages until the 20th century, the three-year rotation was practised by farmers in Europe with a rotation: rye or winter wheat, followed by spring oats or barley, then letting the soil rest (fallow) during the third stage.

	Batch production - Wikipedia, the free encyclopedia
		Batch production is a method used to produce or process any product in groups that are called batches, as opposed to a continuous production process, or a one-time production.
		The products, for example bread, are made in batches of however many will fit in the baker's oven at a time.
		Batch production techniques are used in the manufacture of specialty chemicals such as active pharmaceutical ingredients, inks, paints and adhesives.

		Current practice for the production of flexible polyurethane foams using continuous or discontinuous process involves a polyurethane forming mixture being poured or fed into a foaming space where the polyurethane foam is left to freely expand and rise in contact with air, letting it completely polymerise.
		Moreover, in the continuous process for the production of polyurethane foam, a mixture of a polyol and isocyanate, complete with reactants and blowing agent, is usually poured or fed into a channel-shaped space, provided by sidewalls, fallplates and conveyors lined with a moving substrate.
		According to another aspect of the invention, an apparatus has been provided for the continuous production of flexible polyurethane foam slabstocks, whereby the foaming space is defined by an enclosure extending from the feeding zone of the polyurethane mixture, for the entire length of expansion and growth path of the polyurethane foam.

	Continuous Process
		The conventional process of coatings production is characterized by the use of the batch production philosophy.

	2.3. Algal production
		Furthermore, outdoor production is often characterized by a poor batch to batch consistency and unpredictable culture crashes caused by changes in weather, sunlight or water quality.
		Products such as aluminum sulphate and ferric chloride cause cells to coagulate and precipitate to the bottom or float to the surface.
		Algal production in outdoor ponds is relatively cheap, but is only suitable for a few, fast-growing species and is characterized by a poor batch-to-batch consistency and unpredictable culture crashes due to contaminations and/or fluctuating climatological conditions.

		Attention will be focused on distributed production control methods that are "guided" by the solution of a continuous flow (fluid) approximation of the production system.
		The continuous flow model will incorporate important production control decisions such as part release, routing, and machine scheduling, and will provide part release and operation-specific production targets for the system over a sufficiently long time.
		The vast reduction in computational complexity of the production control problem achieved by the continuous flow approximation allows the computation (and updating) of the continuous production targets in real time.
