Title: Methods for the preparation of an n-bis-[2-(1,2-dicarboxy-ethoxy)-ethyl]amine derivative and products of the methods and their uses
Inventor: RENVALL ILKKA
IPC: C11D3/33
Filed: 1999-03-08
Abstract: The invention concerns methods for the preparation of an N-bis-[2-(1,2-dicarboxy-ethoxy)-ethyl]-amine derivative, products of said methods as well as uses of the products. According to the invention said derivative is prepared by reacting an alkali or earth alkali metal salt of maleic acid with an N-substituted diethanolamine, the reaction taking place with the two ethanol groups of the diamine while the substituent group bound to the N atom remains unaffected, or alternatively by first reacting diethanolamine with an alkali or earth alkali metal salt of maleic acid to yield N-bis-[2-(1,2-dicarboxy-ethoxy)-ethyl]-amine, which is then reacted with a substitution reagent to obtain the final product. The derivative is useful as chelating agents, e.g. in the bleaching of chemical or mechanical pulp or in textile bleaches containing hydrogen peroxide or a peracid, or as a calcium binder in detergents and cleaning agents.

Title: Method and apparatus for vehicle data transfer optimization
Inventor: LAGUER-DIAZ JUAN
IPC: B61L3/12
Filed: 2000-10-27
Abstract: An apparatus and method for identifying and transmitting time critical or high priority files from an on-board monitor aboard a vehicle. During operation of the vehicle, the on-board monitor collects and stores operational parametric information in the form of data files. The data files are transmitted to a remote site on a periodic basis or in response to certain predetermined conditions above the vehicle. To reduce the latency and delay times with transmitting the high priority files, those files are merged and transmitted before the transmission of relatively lower priority data files.

Title: Method and apparatus for the high speed application of coating to a traveling paper web
Inventor: GEORGE BRIAN J
IPC: B05C9/04
Filed: 1997-09-26
Abstract: Apparatus (20, 20b) for coating a traveling paper web (w) includes a coater head (22, 22b) for applying a film of an aqueous slurry of coating material either directly to the paper web, which is supported on the surface of a rotating backing roll (14, 14b), or to the surface of a backing roll (14, 14c') which in turn applies the film to the paper web (w) which is nipped between two backing rolls. The water head (22, 22b-d) includes an inlet (24, 24b) for receiving fresh coating material which is introduced into a mixing chamber (26, 26b).    A looped flow path is established within the water head which includes a feed channel (28, 28b) extending from the mixing chamber (26, 26b) and leading into a coating chamber (18, 18b) where one portion of the coating material proceeds in the direction of the rotating backing roll while another portion of the coating material exits the feed channel in the opposite direction over a baffle (30, 30b). The aqueous slurry of coating material near the downstream end of the coating chamber enters a recirculation channel from which it is directed through a plurality of flow metering orifices (58, 58b) back into the mixing chamber (26, 26b). This looped flow pattern operates to greatly reduce both the entrainment of air in the coating material in the application chamber and the quantity fresh coating material needed properly to coat the paper web, particularly at relatively high speeds desired. The application chamber can either include or not include a flexible blade (36, 36b). A rotating metering bar (40, 40b) is mounted on the coater head downstream of the coating chamber to meter the coating material applied to either the paper web or the backing roll.
