Patent DE-19644932-A1 (DE)
Title: Base-catalysed reaction of 1,3-di:isocyanato alkyl cycloalkane
Inventor: MOSBACH JUERGEN DR
IPC: C07D247/02
Filed: 1996-10-29
Abstract: Base-catalysed reaction products of 1,3-di-isocyanato-alkylcyclohexane R1(NCO)2 in presence of acyclic urethane groups or corresponding isomeric cyclic allophanate groups (and optionally higher homologues) of formula (I) and (II) respectively, are claimed. The products are obtained by reaction of 1,3-di-isocyanato-alkylcyclohexane with polyols of formula A(OH)x. (OH)y-A-(O-CO-NH-R1)x-y-NCOn-x+y (I) A = residue of x-hydric hydroxyl compound;  R1 = residue of 1,3-di-isocyanato-alkylcyclohexane;  n = number of NCO equivalents in the di-isocyanate components;  x = number of OH equivalents in the hydroxy components;  y = (x - n) which is number of optionally unreacted OH groups, i.e. 0-4;  n - x + y = number of NCO groups in the urethane of not more than 4.     The NCO/OH ratio is (0.5:1)-(200:1) and the content of urethane or allophanate groups is 0.05-48 wt% based on the reaction mass used. The process comprises urethane-formation and a simultaneous or subsequent poly-addition reaction with NCO groups in excess (NCO/OH = 1.05:1-200:1), in the presence of 0.00005-10 wt% basic catalyst (in monomeric form or ionically or preferably covalently bonded to a sparingly-soluble matrix) and optionally in presence of air, to give poly-allophanate-polyisocyanates of formula (III) and/or (IV) with an allophanate group content of 2-55 wt%. A--OCO-N(R1-NCO)-CO-N(R1-NCO)m-Hx (III) m = more than 1.05; and  p = 0 or more.    The mixtures obtained have an average NCO functionality of more than 2.1, and contain less than 10 wt% sparingly soluble heterocyclic polyamide-1,1-compounds with no isocyanate groups, less than 10 wt% isocyanurate structures based on 1,3-di-isocyanato-alkylcyclohexane and less than 2 wt% monomeric di-isocyanate starting material.     Also claimed are processes for the production of poly-allophanate-polyisocyanates as above.

Title: Method for measuring directivity pattern of vehicle radar antenna, etc.
Inventor: WAGNER KLAUS-PETER
IPC: G01R29/10
Filed: 1997-01-15
Abstract: The method involves linking the antenna (11) to be measured with an evaluation or reception equipment (10).

Patent DE-19715762-A1 (DE)
Title: New kit for preventing thrombosis and improving blood flow
Inventor: SCHREIBER HANS DR DR
IPC: A61M1/36
Filed: 1997-04-16
Abstract: A kit for preventing thrombosis and improving blood flow works by organ-specific extracorporeal circulation, where plasma from arterial blood is passed through exchange membranes and/or capilleries and absorbers, or where whole blood is directly brought into contact with absorbate-covered polycarbonate elements. This removes any atheroma-forming components from the blood, especially the low density lipoprotein (LDL) fraction of cholesterol. The regenerated blood is then oxygenated and re-introduced via the venous circulation to the relevant organ of the body.

Patent DE-19744470-A1 (DE)
Title: Pressure swing adsorption plant for recovery of materials from gases, removes e.g. polar solvent, especially water from process gases for re-use and releases benign emissions into environment
IPC: B01D53/04
Filed: 1997-10-08
Abstract: A hydrophobic molecular sieve is used for adsorption. Its polar potential derives from loading with a set quantity of polar material, the binding of the product gas resulting exclusively from van der Waals forces.  An Independent claim is included for corresponding equipment carrying out the process.  Preferred features: Desorption is by evaporation under microwave heating. The molecular sieve resists microwaves, not itself undergoing significant heating. This is treated with steam and pressure-compensating gas, e.g. nitrogen or water, its saturation and temperature corresponding with the process gas. This prepares the zeolite for polar binding. Desorption commences with pressure reduction using a vacuum oscillator (see later under pressure oscillator). After pressure reduction to correspond with the water boiling point under conditions in the molecular sieve, evaporation is completed in a second stage, when microwave energy is supplied. The adsorber is a fixed bed, through which the gas is forced by a blower under pressure. It is de-sorbed by pressure reduction and/or blowing-off using dry nitrogen. Desorption takes place under the critical evacuation temperature, controlled from the boiling point of water, at which the water still in the adsorption isotherm. The product gas, however, is already in the desorption isotherm. The molecular sieve is conditioned by a process heater, preheating the reactor and also adjusting the analog moisture of the process gas for the conditioned adsorption bed at the start of the process. The adsorption and desorption beds (interchangeable) are placed in chambers through which process gas flows, holding them at working temperature, such that no capillary condensation takes place in the molecular sieve. Adsorption takes place in a pressure swing plant or a reactor with thermally driven fixed beds or rotor fixed bed system. For desorption a pressure oscillator using four reduced pressure buffer vessels and a vacuum pump, is used, operated by a system of synchronized valves.
