Le 1-butène peut erre mélangé à d'autres hydrocarbures; en particulier quand du butadiène est présent, ce dernier se trouve hydrogéné en monooléfine à 4 atomes de carbone. 1-Butene is isomerized to 2-butene by bringing it into contact with a noble metal isomerization catalyst from group VIII previously treated with a sulfur compound, such as hydrogen sulfide, then with hydrogen. 1-Butene can roam mixed with other hydrocarbons; in particular when butadiene is present, the latter is found to be hydrogenated to a monoolefin with 4 carbon atoms.

Binding machine and cover for use therewith

A machine for binding a plurality of loose sheets into bound pamphlet form is disclosed, together with a cover suitable to receive such sheets. The machine has a stationary base to which a main chassis is fixedly mounted. A movable carriage is mounted for slidable movement with respect to the chassis by means of rollers fixed to the carriage and which slide along the inner side edges of the upper plate of the chassis. When the carriage is in the open position, its upper rear wall is separated from the fixed rear wall of the base, thereby exposing an underlying heating channel and permitting the insertion therein of a cover containing pages to be bound thereto. The chassis is then moved to a relatively closed position, whereby its rear wall approaches the corresponding rear wall of the base, retaining the cover and its contained pages therebetween. A brief heating cycle, utilizing a printed circuit board in the heating channel, then causes the pages to adhere to a pre-glued strip along the inner spine of the cover, which has become somewhat viscous during the heating cycle. The cover is then removed and following a short cooling period, the bound pamphlet is completed. In one embodiment of the cover to be used with this invention, thin flexible strips running parallel to the spine of the cover are affixed to the inner surfaces of the front and rear cover portions to provide sufficient rigidity to retain the pages in a firm binding position in the cover when the carriage is moved to its closed position and the heating cycle is initiated. Other embodiments of the cover provide for adhering different binding members to the cover member to provide binding versatility.

Process for preparing a fatty acid ester composition, useful with hydrated ethanol as a substitute for gas oil; ester composition thus prepared

L'invention concerne un procédé de fabrication d'une composition d'esters d'acides gras, utilisable comme carburant de substitution du gazole, et comprenant au oins 75% en poids d'esters éthyliques par transestérification d'une huile et/ou d'une graisse d'origine végétale ou animale, pouvant contenir des acides libres, ledit procédé étant caractérisé en ce qu'il comprend: a) une première étape dans laquelle on effectue au moins une transestérification acide de ladite huile ou graisse avec de l'alcool éthylique contenant de 1 à 60% en poids d'eau en présence d'un catalyseur acide, à 70.degree. C - 150.degree. C durant un temps suffisant pour transestérifier au moins 75% de ladite huile ou graisse en esters éthyliques, on récupère une phase d'esters éthyliques bruts contenant des acides gras libres et une phase glycérol et on sépare lesdites phases, b) une seconde étape dans laquelle on fait réagir ladite phase d'esters éthyliques bruts à un pH acide avec un alcool choisi dans le groupe constitué par le méthanol, éthanol, propanol et butanol et dans laquelle on distille simultanément l'eau du mélange réactionnel, de sorte que l'on forme des esters additionnels à partir desdits acides gras libres présents dans la phase d'esters éthyliques bruts séparés tandis qu'on diminue la teneur en acides gras libres à au plus 2% en poids de la phase d'esters éthyliques bruts, et c) une troisième étape dans laquelle on fait réagir le produit de la réaction résultant de la deuxième étape avec au moins un mono alcool aliphatique, linéaire ou ramifié de 1 à 5 atomes de carbone en présence d'un catalyseur basique, conduisant à la réduction de la teneur en acides gras libres dans le produit de l'étape (b) et a la formation d'une composition purifiée d'esters d'acides gras. Ces compositions peuvent être utilisées comme carburant de substitution du gazole.
