Title: Towing vehicle for maneuvering aircraft
Inventor: CURTEN FRANZ JOHANNES
IPC: B64F1/22
Filed: 1988-01-22
Abstract: A towing vehicle for moving aircraft without a towing bar has a driving frame (5) with a forked receiving space formed between the wheels of an axle, in which is arranged a retractable and extendable gripping and pulling device (28, 68) that cooperates with a lifting device and that engages the nose wheel (24) of the aircraft, pulling it on a paddle (14) up and down with respect to the driving frame. A single paddle (14) is provided to support the nose wheel (24) in the proximity of the line of influence of the nose wheel load, thus preventing blocking and deforming forces from acting upon the nose wheel (24) while this is pulled or lifted. The paddle can pivot around a horizontal axis arranged on the driving frame, and its pivoting position can be controllably adjusted relative to the driving frame. In a further development, the paddle can additionally tilt at an angle to the horizontal axis, thus preventing unacceptable strains when the towing vehicle carrying the nose wheel follows a curved path. Preferably, the paddle is steered on the driving frame by means of a parallelogram or trapezoid linkage (70, 71, 73, 74).

Abstract: The styrene derivative of the present invention is characterized by comprising a compound represented by general formula (I), wherein at least one of R 1 , Rz, Ra, R 4  and R 5  is a carboxyl group, an alkyl group having 1 to 5 carbon atoms, a hydroxyalkyl group having 1 to 5 carbon atoms, a carboxyalkyl group having 2 to 6 carbon atoms, an alkoxycarbonyl group having 2 to 6 carbon atoms, an alkoxycarbonylalkyl group having 2 to 6 carbon atoms, or an aryl group and the remainders are each a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and R 6  is a sulfur atom or an oxygen atom. The styrene derivative has excellent capability of absorbing an ultraviolet ray having a wavelength form 290 nm, i.e., the shortest wavelength contained in sunrays reaching the surface of the earth, to 360 nm having an effect of causing the change In the plastics. The polystyrene derivative of the present invention is characterized by maintaining high water solubility through polymerization of said styrene derivative and causing no skin absorption, i.e., having high safety to the human body. Since the ultraviolet absorption wavelength region is the same as that which brings about a sunburn of the skin, which renders the polystyrene derivative suitable for use as an ultraviolet absorber. Further, according to the process for preparing the polystyrene derivative of the present invention, the polystyrene derivative can be purified in the stage of a monomer, which makes it possible to provide a polystyrene derivative having high quality and high stability.

Abstract: The invention relates to a process for the processing of environmentally harmful industrial waste, particularly mineral residues, for example filter dusts resulting from the purification of flue gases from communal and industrial incinerators, where the dusts, together with binders, are expediently compressed to form stackable shaped bricks, preferably by the process of lime sand brick production, the binder used preferably being sand, cement and additives. The composition has a particularly high dust content having a weight fraction up to 80%, preferably 67 to 63%, the sand fraction is up to 32%, preferably 30 to 28%, and the cement fraction up to 10%, preferably 7 to 9%. The non-leachable bricks made in this manner landfilling are stacked in a regular fashion next to and on each other, forming accessible control passageways and shafts in the interior of the landfill site, the shaped bricks being tongued and grooved to improve their inherent stability.

Abstract: La présente invention se rapporte à de nouveaux gènes servant à l'expression de protéines. Ces gènes permettent l'expression de protéines qui sont normalement retenues à l'intérieur d'une cellule, afin qu'elles soient transportées hors de la cellule ou qu'elles se lient à la membrane cellulaire de la cellule. La présente invention se rapporte en outre à de nouveaux gènes servant à l'expression de protéines qui sont naturellement transportées hors de la cellule ou liées à la membrane de la cellule. Les nouveaux gènes de la présente invention sont particulièrement utiles dans l'expression d'antigènes de rotavirus et notamment de la protéine de rotavirus VP7 qui est normalement retenue dans le réticulum endoplasmique de la cellule. En permettant l'expression de protéines, telles que la protéine de rotavirus VP7, sur la membrane de la cellule ou sous une forme transportée hors de la cellule, on obtient un procédé avantageux qui permet de produire cet antigène pour son utilisation dans des vaccins.
