Title: Process for preparing hexamethylene diisocyanate
Inventor: AJIOKA MASANOBU
IPC: C07C67/00
Filed: 1985-11-18
Granted: 1987-07-23
Abstract: Hexamethylene diisocyanate (HDI) is prepared by simultaneously introducing a hexamethylene diamine (HDA) solution and an equivalent amount or more of hydrogen chloride gas into a turbulent zone in the vicinity of a stirrer blade in an inert organic solvent held in a tank-shaped reactor while being stirred, and passing them through, giving rise to a salt-forming reaction, in such a manner that a highly concentrated slurry of hexamethylene diamine hydrochloride (HDA . HCl) is obtained, and then reacting the slurry with phosgene. Phosgenation is effected by an HDA . HCl slurry having a high concentration, as obtained via the above process, being introduced into a tank-shaped reactor which is held at a pressure above atmospheric pressure but below 5 bar above atmospheric, and the amount of phosgene which has to be injected into the reactor being controlled to a level, in terms of moles, of from 1 to 18 times per hour of the total amount of HDA . HCl and HDI in the reaction mixture. In a preferred embodiment of the phosgenation, the phosgenation reaction is carried out in a continuous two-stage tank-shaped reactor, the degree of conversion in the first stage being controlled to be between 70 and 95%. This is a more efficient preparation process for hexamethylene diisocyanate, as it requires a shorter overall phosgenation time.

Patent DE-3631677-C1 (DE)
Title: Method for digital regulation of an actuating signal for a servomotor (actuator, actuating motor), and a circuit arrangement for carrying out this method
Inventor: RUPP JOSEF
IPC: G05B11/18
Filed: 1986-09-18
Granted: 1987-12-03
Abstract: The invention relates to a method for digital regulation of an actuating signal (Xa) for a servomotor, and to a circuit arrangement for carrying out this method. An input signal (Xe) is produced by comparison of a required value with an actual value. A switching signal (Xg) is formed by subtraction of a low-pass filter signal (Xr), which is produced by low-pass filtering of the actuating signal, from the input signal (Xe). This switching signal (Xg) is used to derive an actuating signal (Xa) which becomes positive if the switching signal (Xg) is greater than a predetermined first threshold value g2, and becomes negative if the switching signal (Xg) is less than a predetermined second threshold value h2, and becomes zero if the switching signal (Xg) is less than a predetermined third threshold value g1 or is greater than a predetermined fourth threshold value h1, the separation between the first and second threshold values forming a neutral zone, and h2 < h1 < g1 < g2. Before regulation commences, the neutral zone is enlarged if a digital computation arrangement determines that, in the steady state, values of the low-pass filter signal (Xr) which are successive in time cause, in the case of the given neutral zone, an extreme change from one extreme value to the other of the actuating signal (Xa). The input signal (Xe) then also has superimposed on it an amount which is formed by the digital computation arrangement. <IMAGE>

Title: Rotor housing, especially housing for turbine engines
Inventor: SIKORSKI SIEGFRIED
IPC: F01D21/04
Filed: 1993-08-28
Granted: 1995-01-05
Abstract: A vibration damper for rotor housings has a rubber-elastic damping band 6, which surrounds the outer circumference of the housing conforming closely to the contour and is fixed on the housing 4 by a clamping band 7 bearing on the damping band. The difference in the modulus of elasticity between the housing material and the clamping band material results in a de-tuning of the oscillation system comprising the rotor housing and vibration damper; this in turn reduces the susceptibility of the rotor housing to vibrations and furthermore, for the friction between damping band and housing surface on the one hand and between damping band and clamping band on the other, to a damping of the vibration. The fixing of the vibration damper on the rotor housing is of releasable design, so that the housing remains accessible for maintenance and inspection purposes. <IMAGE>

Title: Automatic start/stop mechanism for randomly coupled vehicles
Inventor: MEILER BERNHARD
IPC: F02D17/04
Filed: 1994-06-01
Granted: 1995-03-23
Abstract: The engine of manually coupled vehicles is activated at the start of the operation of the vehicles and deactivated at the end of the operation of the vehicles. The invention ensures a coordinated switching on and off of the vehicle when it is stationary for a relatively long time, such as for example at traffic lights, in traffic jams or at railway crossings. The invention consists of an engine sensor A which transmits to a coupling sensor B a signal a when the engine is operating and a signal b when the engine is deactivated, which coupling sensor B transmits to a vehicle stationary-state indicator a signal c when the coupling is closed and a signal d when the coupling is open, said vehicle stationary-state indicator transmitting a signal e when the vehicle is stationary. The signals d, b and e are conjunctively logically connected by means of logic element D which transmits an output signal f to the starter to activate it. The signals c, a and e are conjunctively logically connected by means of logic element E which transmits an output signal g to a switch-over element F for loads and to the switch-off device of the engine. This circuit can be supplemented by means of a logic element H which conjunctively logically connects an idle-motion sensor G to coupling sensor B in order to make the switching-off process functionally more reliable. The drawing shows the extended version. <IMAGE>
Patent DE-4433376-C1 (DE)
Inventor: KUNZ PETER M PROF DR
IPC: C23G5/00
Filed: 1994-09-20
Granted: 1996-04-04
Abstract: The invention concerns an agent, based on organic compounds obtained from micro-organisms, for removing rust from metal surfaces corroded with iron oxides. Rust is normally removed from metal articles using corrosive baths containing organic and/or inorganic acids which, owing to the concentrations used, must meet certain safety requirements and entail costly disposal procedures once the baths are depleted. Iron-absorbing products obtainable using biological methods are generally active in the neutral pH range, eliminating the salt production and contamination of the effluent associated with the neutralisation process normally required. Rust can be removed using reproducible intra- or extra-cellular products which have a high affinity with iron ions. The proposed agents are produced by culturing appropriate organisms in a suitable medium in such a way that they are stimulated to produce these agents. The articles requiring de-rusting are then treated by being dipped in or painted with the agent. Provision of appropriate supports to immobilise the articles facilitates use of the agents and permits recycling of the agent by suitable treatment.
