Filed: 1990-07-04
Abstract: A vehicle, preferably a commercial vehicle, is fitted at the rear with an aerodynamically operating device to reduce the air resistance in the form of an air hose (3) which automatically inflates during the journey. The air hose preferably forms part of the rear surface (1), whereby the rear area (1) is double-skinned at the outer edges, i.e. at both sides of the rear, and at the top so that a hose body closed on three sides is produced.

Title: Use of motor-driven vibrating pile hammer - involves acceleration to operational RPM with masses in balance and activation of unbalance masses when desired RPM is reached
IPC: E02D7/18
Filed: 1991-12-03
Abstract: The hammer is for ramming and/or drawing of ramming equipment. It has two or more unbalance generators, with controllable static momentum. The RPM of the hammer without active unbalance mass, may be raised to above the critical level, and the mass is moved into its operating position above that level. It may be moved into the balance position above this critical level, when the RPM is being reduced. The motor-driven generators each have at least one unbalance mass. These (10,11) are fastened to the associated shaft (8,9) so as to be adjustable relative to the inactive unbalance radius. Adjustment is synchronous, in the same direction, and continuous in radial direction of the unbalance radius. USE/ADVANTAGE -  Pile driving hammer avoids damaging resonances during ramming and/or drawing, and is of simple construction.

Abstract: The cyclic polyiminoethers described are bis-, tris- or tetrakis-isoxazolines of the formula (I), in which n is 2, 3 or 4; A is a carbonyl group or the acyl unit of a di-, tri- or tetracarboxylic acid with 2 to 20 C-atoms; R is hydrogen or an alkyl, alkenyl or aryl group with not more than 12 C-atoms; M is a direct linkage or a double-bonded group with not more than 12 C-atoms, selected from the group comprising alkylene, alkenylene, arylene and alkylarylene, which may contain ether oxygen atoms in the carbon chain, whereby R and M may be substituted by alkoxy groups with 1 to 3 C-atoms. The new polyiminoethers can be prepared in almost quantitative yields from polycarboxylic-acid esters of the formula (II): A(-O-R')n, in which A and n are as defined above and R' is an alkyl group with 1 to 4 C-atoms, by an ester interchange reaction with n moles of a hydroxyoxazoline of the formula (III), in which all the symbols are as defined above. The polyiminoethers described are intermediates with a wide range of applications. A preferred field of application is in processes for the production of cross-linked polymers, the polyiminoethers being used alone, or preferably together with other low-molecular or polymeric starting materials. Particularly preferred are polymeric coatings, consisting of the bis-, tris- or tetrakis-isoxazolines described, on rigid substrates. Such coatings have shown themselves to be extremely resistant to the action of light and solvents.
