Abstract: Verfahren zur Auftrennung der bei der Verätherung von C4-C7 Isoolefinen mit Methanol anfallenden Reaktionsprodukte durch Wasserwäsche in Gegenwart von inerten Kohlenwasserstoffen, wobei der Methanol und tertiäre Alkohole enthaltende Alkoholanteil vollständig mit Wasser extrahiert wird, die wäßrige Extraktlösung sich im Sumpf der Waschkolonne sammelt und von dort in eine Destillationskolonne geleitet wird, in der die Alkohole destillativ abgetrennt werden und tertiärer Alkohol als Seitenstrom abgezogen und in eine Abstreifkolonne übergeführt wird. Das vom Kopf der Abstreifkolonne abgezogene Methanol wird in die Destillationskolonne zurückgeführt, während der im Sumpf der Abstreifkolonne anfallende tertiäre Alkohol ausgeschleust oder dem Strom für die Kohlenwasserstoff/Äther-Trennkolonne zugemischt wird. Der tertiäre Alkohol sammelt sich dann im Sumpf der Trennkolonne als Komponente des trockenen und methanolfreien Ätherproduktes.

Abstract: La grille comprend une pluralite de passages de lumiere (3) delimites par des parois (4, 5, 6, 7) de hauteur appropriee et disposes a une distance mutuelle appropriee permettant a la lumiere emise par une source lumineuse (9) de se propager dans lesdits passages de lumiere. La grille comprend au moins deux organes de grille plans independants et paralleles (1, 2) disposes l'un pres de l'autre ou ecartes d'une distance predeterminee. Les organes de grille peuvent etre fixes l'un a l'autre par de moyens de retention (8), par exemple des connexions rapides. Les organes de grille peuvent etre du meme type ou de types differents de telle sorte que, par exemple, les deux organes soient des grilles ecran ou que l'un des organes soit une grille ecran alors que l'autre, de preference l'organe de grille inferieur, peut etre une grille a basse luminence a miroir. En fabriquant une grille constituee de deux organes espaces il est possible de placer les parois (4, 5, 6, 7) a une distance plus grande, ce qui permet une economie de materiau tout en maintenant l'angle d'ecran habituel. Une telle construction permet en outre de reduire l'epaisseur des parois par rapport aux grilles de types connus, ce qui implique une economie de materiau supplementaires. Le poids total de la grille est ainsi reduit de facon notable. De plus de nouveaux effets lumineux sont rendus possibles en donnant des couleurs differentes aux organes de grille.

Abstract: Wood and wooden materials are treated with aqueous treatment media. These media contain a water-soluble or water-dispersible, oxidatively drying, organic binder. The latter is a low-molecular weight, optionally modified 1,3-butadiene polymer which carries quaternary ammonium groups. This polymer is obtained by reacting an epoxy-group-containing polymer with a secondary and/or primary aliphatic amine and reacting the amination product with a low-molecular weight monoepoxide, during which process 0.05-0.5 mole of the quaternizable amino groups is quaternized per 100 g of the amination product. The treatment media preferably additionally contain wood preservatives and additives customary in the impregnating and varnishing field.

Abstract: An engine governor (30) has overriding means (38, 50) for limiting the flow of fuel to an engine (20), means for moving the overriding means to an intermediate reference position upon actuation of the governor, and means for moving the overriding means from the reference position to other positions for limiting the flow of fuel to that suitable for operating the engine at speeds close to a set speed. Means for actuating the governor before the engine reaches the set speed, means for moving the overriding means from the reference position to the other limiting positions at a very slow rate, and means for moving the overriding means toward limiting the fuel flow to a minimum when an over-running load causes the engine speed to run a predetermined amount above the set speed. The engine governor may be combined with a load speed governor (86) for independently governing the engine to a speed safe therefor, and to a lower speed safe for a load (24) and may also have a power take-off governing mode which is selected automatically upon connection of the power take-off to the engine.
