Patent CA-2187066-A1 (CA)
Inventor: STREITBERGER HORST
IPC: B01D11/04
Filed: 1996-10-03
Abstract: The invention relates to a process for removing salts or water-soluble substances from a nonaqueous, water-miscible scrubbing liquid in gas scrubbers, which comprises feeding water to the scrubbing liquid until an aqueous phase separates out from the scrubbing liquid, and taking off this aqueous phase. The advantages of the process according to the invention are essentially that it circumvents the salting of the scrubbing media by a continuous removal of salts from such scrubbing processes.   Alkyl ethers particularly suitable for the process are, for example, the polyethylene glycol dimethyl ethers having a mean molar weight between 200 and 700, preferably 250 to 550. Corresponding compounds are sold, for example, by Hoechst AG (D-65926 Frankfurt am Main) under the trade name Genosorb.

Title: Service provision system for communications networks
Inventor: BUSUIOC MARIUS-NICOLAE
IPC: H04M15/00
Filed: 1995-04-28
Abstract: A services management sys- tem, which can provide services to a mobile user, can do so via a com- bination of network platforms (10). The system uses "Co-operating In- telligent Software Agent" technol- ogy in a heterogeneous agent archi- tecture (25) to provide enough flex- ibility to deal with changing net- work constraints, for instance as the user moves. In an example, a fixed broadband network might be used in combination with radio transmitters of a mobile network. The agent architecture (25), in- volving autonomous agents work- ing co-operatively, forms a layered system using the underlying fixed network (1) for inter-agent commu- nication. In an application, a mo- bile user might move from a cell of the mobile network which can provide relatively wide bandwidth to one which can only provide lim- ited bandwidth. The service man- agement system can advise the user what services are available in ei- ther cell, at what price, based on current bandwidth usage at the two locations. If the user was already using a service which became unavailable in the new cell, the system will ad vise the user and, if appropriate, put the service effec tively on hold until the user enters a cell in which the service is available once mor e.

Filed: 1997-08-11
Abstract: An apparatus for creating revascularization channels in tissue, such as the myocardium of the heart, mechanically cuts the channels using a hand piece with easily removable cutting tip assemblies having angled, sharpened edges to allow rapid tip replacement.  The cutting tip assembly has an inner  needle within an outer hollow needle with each needle attached to the hand piece for independent rotation and axial movement.  The inner needle may be hollow, or formed with a pointed tip, and may rotate counter to the outer needle to enhance gripping and storage of the tissue excised by the outer needle.  The hand piece may attach a cylindrical magazine of cutting tip assemblies or one cutting tip assembly.  The cutting tip assembly may be heated to provide thermal damage to the heart muscle during the creation of the channel, providing some of the advantages of the laser method of TMR.

Abstract: The present invention relates to a method for producing security paper which includes a security feature. The method comprises forming paper in a wet state, which paper incorporates on or more security features, applying to the paper a sizing agent, thereafter applying to one or both sides of the sized paper a coating comprising an unpigmented polyurethane. The unpigmented polyurethane may optionally comprise a functional additive provided that the presence of the functional additive does not increase the opacity of the paper by more than 1 %. After the polyurethane has been applied the paper is dried. The coating composition provides a film, when cast on a glass surface, having a König hardness of from 15 to 130 seconds, and also passes the water resistance test as defined by the following steps: a) the total formulation to be used in the coating is cast on a glass plate so as to produce a film with a dry weight of 80 g/m2; b) the film is initially dried at 23°C. Once it is tack free it is dried for an additional hour at 80°C; c) the film is weighed before being wetted and tested for tensile strengths, Young's Modulus and is visually checked for any change in its transparency; d) a sample of the film is boiled in water containing 10g/litre Na2CO3 for 30 mins; e) the film is then rinsed in cold water and the steps b) to c) are then repeated; wherein when the film is dried and re-weighed the film meets the following criteria: i) the wet tensile strength and Young's Modulus of the boiled film is not less than 90 % of the initial film wet tensile strength and Young's Modulus; ii) the film shows no perceptible loss of transparency; and iii) the dried weight of the film is not less than 98 % of the original weight.
