Title: Radiological operating system - interpolates absorption data by forming signals representing differences
IPC: G16H10/60
Filed: 1975-07-21
Abstract: The system constructs a pattern of the distribution of absorption into a body surface, generating data signals representing radiation absorption along a series of parallel tracks on the surface concerned. By interpolation between these signals further signals are obtained representing absorption along a larger number of such tracks. At each of a number of predetermined points the data signal or other ones are allocated belonging to the track whose centre is closest to the point concerned. Interpolation is carried out by forming signals representing differences from the data extending to the mth order, m being at least equal to two of these difference signals. The subdivided differences are combined by continuous addition.

Patent NL-8801766-A (NL)
IPC: C05F17/02
Filed: 1988-07-12
Abstract: In the procedure for producing composte from manure by means of fermentation, in which an oxygen-containing gas and also a gaseous and/or vaporous phase originating from the manure is passed through the manure, the temperature of the manure rises. In order to avoid the temperature rising too high, the gaseous and/or vaporous phase is subjected to cooling outside of the manure to form an ammonia-containing aqueous phase and a residual gas phase. Furthermore, the ammonia is evaporated form the aqueous phase and supplied to the manure along with the residual gas phase. In this way, the ammonia which was hitherto lost in the atmosphere can also be converted into nitrates in the manure, resulting in a higher quality for the manure. Furthermore, less ammonia is discharged in the environment, resulting in less acidification

Title: Method for producing mold-shaped ceramic bodies
Inventor: LAROCHE EVANS ALLEN JR
IPC: C04B35/65
Filed: 1988-01-06
Abstract: A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a gas-permeable, conformable material (20) to a shape-defining surface of a shaped parent metal (10). The gas-permeable material (20), when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface. Upon heating, the parent metal (10) melts and flows from the mold into a receptacle without disturbing the mold. Oxidation reaction product is then grown by oxidation of the molten parent metal with a vapor-phase oxidant to form an oxidation reaction product which grows into the mold cavity and is shaped by it. A ceramic body is recovered from the mold and has substantially the same shape as the pattern section (12,14,18) of the original shaped parent metal (10).
