Granted: 2000-12-19
Abstract: A porous structure of a water-swellable, water-insoluble polymeric material which porous structure possesses unproved free swell capacity and is able to demonstrate said improved free swell capacity when in contact with an absorbent material such as a cellulosic fibrous web. Also disclosed is a method of making such a porous polymeric structure. The method comprising the steps of forming an oil-in-water suspension, wherein the water phase contains a water-soluble monomer and a crosslinking agent and the oil phase is a volatile organic compound having a boiling point greater than the boiling point of water. The monomer present in the water phase is polymerized to form a polymeric material having dispersed therein the oil phase. The resultant polymeric material is then dried at a temperature above the boiling point of water, such that the volatile organic compound volatilizes thereby forming pores in the polymeric material, which pores have a diameter of at least about 20 microns. The polymeric material is at least partially dried before the organic compound volatilizes so that the polymeric material possesses sufficient structural integrity to maintain the openness of the chambers.

Title: Method and apparatus for increasing two tier macrocell/microcell subscriber capacity in a cellular system in which microcell access by a mobile is dependent on a mobile's vehicular speed
Inventor: BENVENISTE MATHILDE
IPC: H04W16/32
Filed: 1993-03-09
Granted: 1999-08-10
Abstract: A particular method for enabling the service of mobiles by a microcell, in a two tier cellular system, involves identifying a microcell coverage area and offsetting microcell signal strength for a time sufficient to allow a fast moving vehicle, desiring service and having entered the microcell serving area, to exit the microcell coverage area before the call is set up or handed off forcing the controlling macrocell to handle the call setup or handoff. Hence only the mobile radiotelephones of stationary and relatively slow moving vehicles are served by the microcell.      There is a substantial offset-coverage overlap period between the locations where a mobile may be found during the offset interval or duration of the apparent reduced signal strength of the microcell and the microcell coverage area. Calls that could be serviced by the microcell are instead serviced by the macrocell because the mobile radiotelephone responds to the strongest signal.      This loss in capacity is solved by reducing the offset-coverage overlap. Offset-coverage overlap is reduced by starting the offset or timed duration in response to a broadcast signal sent by the microcell at some predetermined point before the mobile enters the microcell coverage area and by increasing the length of the offset duration or interval by some predetermined increment to prevent service by the microcell to a vehicle exceeding a cutoff speed. Far slow moving vehicles then is a net shift to a reduced offset period within the microcell coverage area and hence proportionately more call setup and handoff requests of slow moving vehicles can be accommodated.      Service permissions for call setup with microcells may also be based on certain identification associated with mobile radiotelephones.

Abstract: A hardware arrangement is provided for transforming plaintext into corresponding ciphertext.  The plaintext includes a plurality of words each having a predetermined bit length.  The hardware arrangement sequentially acquires the words and exhibits a predetermined number of arithmetic operations on the word acquired.  Each of the arithmetic operations includes a plurality of arithmetic processes.

A selector is arranged to receive two inputs and selectively output one of the two inputs.  One of the two inputs corresponds to the word acquired.  A multiplier is coupled to receive the output of the selector.  The multiplier multiplies the output of the selector by a multiplier and outputs a product therefrom.  An adder is coupled to receive the product.  The adder adds the product and an addend and then outputs a sum.  A divider is coupled to receive the sum such as to divide the sum by a modulus and outputs a residue therefrom.  The value of the modulus is subject to change at each of the arithmetic operations.  The residue is applied to the selector as the other of the two inputs.

Title: Process for the production of a pyrogen-free fructan which is readily water-soluble as well as renal diagnostic agent containing such a fructan
Inventor: NITSCH ERNST
IPC: A61K31/733
Filed: 1992-01-21
Granted: 1998-11-24
Abstract: A process is described for the production of a readily water-soluble fructan as well as a well-tolerated renal diagnostic agent containing such a fructan. In the process an aqueous fructan extract obtained from parts of plants is ultrafiltered over a first membrane which retains carbohydrates and proteins with a higher molecular weight but which allows passage of fructan and the filtrate obtained in this way is then filtered in a second ultrafiltration through a membrane which retains fructan but which allows passage of salts and low-molecular substances such as monosaccharides and oligosaccharides. The fructan obtained in this way is used as a renal diagnostic agent together with physiologically tolerated buffer substances at an osmolality which corresponds to that of blood and which has a pH of 5.0 to 7Ø

Title: Method and apparatus for immobilized enzyme reactions
Inventor: AFEYAN NOUBAR B
IPC: C12N11/00
Filed: 1992-04-09
Granted: 1995-12-12
Abstract: Perfusive matrices (10) useful in immobilized enzyme reactors (IMERs) are disclosed. The matrices define first and second interconnected sets of pores and an intraparticle high surface area (18) capable of immobilizing enzymes, in fluid communication with the second set of pores. The first and second sets of pores are embodied, for example, as the interstices (12) among particles and throughpores (14) within the particles. The particles also contain diffusive transport pores (16). The dimensions of the first and second sets of pores are such that, at fluid flow rates and pressure drops practical for immobilized enzyme reactions, convec-tive flow occurs in both pore sets, and the convective flow rate exceeds the rate of diffusion of the substrate and product to and from immobilized enzymes within the particles. This approach allows rapid enzyme loading and substrate conversion reactions at optimal catalytic flow rates.
