Title: Personal telecommunications system
Inventor: PATEL RAJENDRA
IPC: H04M11/00
Filed: 1992-05-27
Abstract: ABSTRACT          The location independent personal telecommunications system of the present invention enables a subscriber to have a single personal telephone directory number. When that personal telephone number is dialed, the system uses the existing public and cellular communication systems and a service node all comprising parts of the personal telecommunications system to route the call to the present, or last known location of the subscriber. The location of the subscriber is determined by the personal telecommunications system through a radio tracking system comprised of a number of radio base stations that monitor the subscriber's location by communicating with a personal communicator carried by the subscriber. The subscriber location information is transmitted from the base stations to the service node for storage and subsequent access when a call is placed to the subscriber's personal telephone number. The service node will then transfer the call to the proper telephone number at the location where the subscriber is currently, or last known to be located, or if not at a fixed location with a known phone, notify the subscriber through the base stations and the personal communicator of the incoming call.
Patent CA-2071768-A1 (CA)
IPC: F24F3/14
Filed: 1992-06-22
Abstract: The present invention describes a method and apparatus for conditioning air utilizing a desiccant based air conditioning system  requiring  substantially  less  regeneration  energy  than typical  systems.     This  regeneration  energy  reduction  is accomplished through the use of two separate desiccant devices and an indirect evaporative cooler having both a wet and dry side for air flow-through.  The first desiccant device regeneration air is first passed through the wet side of the indirect evaporative cooler wherein it is humidified and heated.   This air is then dehumidified by passing through the second desiccant device which operates at a high moisture content.  This results in a substantial amount of moisture being adsorbed from the first regeneration air stream causing a substantial air temperature increase and thereby, reducing the auxiliary heat required.  The second desiccant device may be regenerated with ambient air.

Title: Bio specifically recognizing surfaces on solid supports and method for their preparation
Inventor: BARNER RICHARD
IPC: G01N33/53
Filed: 1993-06-22
Abstract: The biologically recognising layer on a solid phase consists of biologically recognising molecules comprising regions which recognise (bond) the substance to be analysed and regions which do not recognise (do not bond) the substance to be analysed.      The biologically recognising molecules are aligned on a suitably modified surface by means of molecular regions which do not recognise the substance to be analysed. The biologically recognising molecules are cross-linked with the aligning surface and are consequently covalently altered. The molecular regions recognising the substance to be analysed are not altered by the covalent bonding and retain their bonding activity.      The layer is produced in a novel two-stage method. In the first step, the biologically recognising molecules, the aligning molecules and the carrier molecules are adsorbed. In the second step the molecules are covalently anchored by cross-linking. Cross-linking is brought about by photolytic activation of the reagent bonded to the carrier molecules.      Even after reacting with the earner molecules the reagent contains water-solubilising groups.
