Abstract: A method of producing 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) by nitrosation of 1,3-bis(2-chloroethyl)-urea utilizing as a nitrosating agent dinitrogen trioxide (N2O3) in molar excess of theoretical wherein the molar excess of N2O3 ranges from 10-200% and preferably from 10-20%. The nitrosation reaction is conventionally carried out in the cold from 0 DEG  C to -20 DEG  C and a non-aqueous solvent is utilized. The preferred non-aqueous solvent is of the chlorinated variety; i.e., methylene dichloride. Other preferred solvents include related halogenated compounds such as ethylene dichloride, nitro-compounds such as nitromethane, acetonitrile, and simple ethers such as ethyl ether. Other less preferred but operable compounds include esters such as ethyl acetate, simple ketones such as acetones, and chloroform. Solvents to be avoided are olefins, unsaturated ethers and other unsaturated compounds, amines, malonate esters, acid anhydrides, and solvents which would interact with the reactant N2O3 and the urea as well as the product nitrosourea.

Abstract: Organic waste and/or sewage sludge is digested by passing it downwardly through a closed vessel while air is passed upwardly through it. The air is finely divided or distributed into the vessel so that it flows through the entire cross sectional area of the material being digested. The flow of air through the vessel is regulated by measuring the content of CO2 or O2 in the exhaust air from the vessel and comparing the measured value with a desired value. Similarly, the moisture content of the material being digested is measured in at least two spaced locations and the moisture content is compared with a desired value for determining the amount of water to be supplied into the air flowing into the vessel. In addition, the air supplied to the vessel is heated based on the temperature conditions to be maintained within the vessel. After exhaust air leaves the vessel, its heat and water contents are withdrawn and it is filtered to remove objectionable odors and other noxious matters.

Abstract: In tomosynthesis, plural sources 1, 2, 3, 4, form shadowgraph images P1, P2, P3, P4 of an object with features A, B from different perspective directions. In synthesising a selected sectional image the images P1 ... P4 are superposed with appropriate shift to cause corresponding image point locations defining the selected layer to overlap and reinforce one another. The present invention reduces the effect of background image points from other layers by a process of selection or enhancement logic which is applied to each set of overlapping local image values relating to a corresponding image location in the selected section, to allocate to that location a related image value or a substantially zero value depending on whether the image detail is assessed as lying in the selected section or not. In one embodiment, Figure 4, the images P1 ... P4 are each scanned in 5 lines Z1 ... Z5 to form a corresponding video signal 9 which is applied to a parallel storage arrangement with different shift delays O,  DELTA  t1,  DELTA t2,  DELTA  t3. The overlapping signal values at each location Pn1 ... Pn4 are processed by an analyser 10a which causes a control stage 10b to transfer an image signal to an output register Sn for display only when a signal exceeds a threshold in all or most component images. Alternatively (Fig. 7 not shown) images P1 ... P4 can be multiplied together using a Titus tube, polarised light beam and associated television equipment. <IMAGE>

Abstract: An evacuable tube (30) is used to separate two optical elements (32, 34) spaced at a known predetermined length L. A laser interferometer (20) is arranged to measure the change in apparent distance  DELTA between the elements (32, 34) when the tube is filled with ambient air and when the tube is evacuated. An interferometer calibration factor VA can then be determined from the equation  VA=1- DELTA /L, where VA is the ratio of the wavelength of light in vacuum to the wavelength of the light in ambient air. This calibration factor VA is used to correct further interferometer measurements for existing ambient environmental conditions of temperature, relative humidity and atmospheric pressure. <IMAGE>
