Patent EP-0075384-A1 (EP)
Inventor: MOORES WILLIAM D
IPC: E02B15/00
Filed: 1982-08-04
Abstract: A process is provided for preparing a novel highly oil absorbent peat product useful to control oil spills for oil spill clean up. The process involves first preparing an initial mixture by mixing peat with an alkaline earth metal basic product, e.g., a magnesium/calcium hydroxide lime substitute material, e.g., at a ratio of about 1:15 to about 1:45. Then, that mixture is partially dried by heating either directly in an oven or a microwave oven or indirectly by a heat exchanger for a predetermined period of time, e.g., at a maximum temperature of about 150°C, for a maximum time of about 15 minutes. Then, a further mixture is prepared by mixing additional such basic material with the partially dried peat, e.g., magnesium/calcium hydroxide lime substitute material with the partially dried peat, e.g., at a ratio of about 1:10 to about 1:20. The further mixture is then heated, either directly in an oven or a microwave oven or indirectly by a heat exchanger, e.g., at a maximum temperature of about 150°C for a maximum time of about 15 minutes until the peat has the desired moisture content, e.g., about 5-10%. This novel product can absorb some 20 times its own weight of oil which makes it very advantageous for cleaning up oil spills either on land or on water. Also, the oil contained in the absorbent after it has been used to clean the oil spills may be easily removed.

Abstract: There is disclosed a method for treating waste material containing metal and/or metal oxide, organic material and optionally also water, for the purpose of separating the organic material and any water present in vapour form. The waste material is heated indirectly while continuously advancing the waste material through a screw housing (12, 13) by means of a screw, the heat being supplied in a quantity such that the volatile constituents of the waste material are converted to gas and/or vapour form. The resultant gases and vapours are used as fuel for heating the waste material in the screw housing. The screw housing (12,13) is only partially filled with material being treated, so as to form a vacant space in which the generated gases and/or vapours collect. The generated gases and/or vapours are discharged from the screw housing without contacting the material being treated and/or the material to be treated, and are supplied, optionally after partial condensation of gas and/or vapour originating from the organic material, to a combustion chamber (48) for generating combustion gases, which are used to indirectly heat the material in the screw housing.

Abstract: Le dispositif présente deux cadres (1, 3) reliés entre eux par un axe de rotation (2) et tenus écartés l'un de l'autre par des barres de torsion (6, 7) et par des ressorts pneumatiques (12, 13) précontraints et disposés près de l'axe (2). Le cadre supérieur incliné (3) sert d'appui pour la partie d'un matelas située près de la tête d'un sommier. Dans le but de modifier l'angle d'inclinaison du cadre supérieur (3), on prévoit, fixés sur celui-ci, des câbles en acier (14, 21), qui sont déviés par des poulies (15, 16, 17, 22, 23, 24) disposées sur l'autre cadre (1) et reliés à un levier pivotant (19) sur ce dernier cadre (1) et actionné par un moteur de levage (26). En actionnant le moteur de levage (26) dans un sens, les câbles (14, 21) font pivoter un cadre (1) contre l'autre (3) et contre la réaction des barres de torsion (6, 7) et des ressorts pneumatiques (12, 13). En l'actionnant dans le sens contraire, les cadres (1, 3) s'écartent l'un de l'autre sous l'effet des barres de torsion (6, 7) et des ressorts pneumatiques (12, 13).

Abstract: It is necessary to determine the effects of welding pressure in order to control the high-frequency welding process in the manufacture of pipes with longitudinal seams. It has been discovered that measurements of the height of the welding bead provide an approximation that is satisfactory for determining the mass of the bead, which is proportional to welding pressure in known pipe geometry. The height of the bead is transmitted by an optical system to the diode matrix of a commercially available diode-matrix camera. The results are processed to control welding pressure.

Abstract: The filtering capacity of a honeycomb filter (30) having a plurality of cells (34) formed by a matrix of thin, porous intersecting wails (31) and used for removing solid particu- 'ates mixed in fluids is improved by providing a porous outer wall (35) around the thin wails (31) through which the fluid is also filtered. A particulate barrier (40) is provided between the outer wail (35) and a conduit (20) carrying the contaminated fluid to and filtered fluid from the filter (30) which allows the fluid to flow along and through a substantial portion of the porous outer surface of the filter while preventing contaminated fluid from bypassing the filter. The barrier (40) s preferably formed near an inlet or an outlet end face of the filter and those cells which are located around the periphery of the end faces are preferably open at the same end face and closed at the remaining end face to ensure fluid flow across the porous outer wall (35).

Abstract: Alkyl aromatic hydrocarbons and their halogenated substitution products are partially brominated in a liquid phase reaction within the still head of a distillation system. Liquid bromine is introduced in the still head through side-arm 16, mixed with condensed hydrocarbon in zone 14 and reacted in chamber 15 when irradiated with UV or visible light of wavelength shorter than 550nm. The higher boiling partially brominated hydrocarbon formed returns to flask 11 via distillation column 17 and unreacted materials are recycled. 
     The brominated products, particularly tetrafluoro-p-xylyl bromide and pentafluorobenzyl bromide, are useful intermediates in the synthesis of, for example, insecticidal compounds.
