Abstract: A method of selecting information sources from which information is provided to users via a telecommunications system, the method comprising: tracking the location of a user in the system by receipt of tracking information for the user; accessing location data indicating localities in which information from the respective sources is deemed to be relevant; generating a shortlist of information sources for the user on the basis of the tracking information and the location data; and transmitting the shortlist to a terminal associated with the user so as to allow the user to select an information source of interest and thereby to access information from the source.

Abstract: A system for creating a coil of stamps from a web of stamp material having an adhesive applied to a side thereof is provided. The system includes an anvil and a perforation die cooperating therewith with the web passing therebetween in order to perforate the web. The web is passed between the anvil and the die with the adhesive side thereof facing the anvil. The anvil is chilled so as to inhibit the adhesive from adhering thereto as the web is perforated. The anvil may be chilled from an outer surface thereof, or may be hollow and chilled from an inner surface thereof. In the former case, the system preferably includes a trough holding a chilling material through which at least a portion of the outer surface of the anvil is passed. Where the anvil is chilled from an inner surface thereof, a cooling fluid is preferably passed therethrough.

Abstract: A coil of stamps is formed from a plurality of self-adhesive stamps detachably connected to each other end-to-end to form a continuous strip. Because the stamps include a primer layer, it is practicable to wind the strip about itself in spiral-like fashion. The strip also includes a portion adjacent to the inner end of the strip having a piece of liner material disposed thereon, and a portion having no liner material thereon, whereby the portion having no liner material thereon allows the strip to be wound directly onto itself. Preferably, the strip of stamps also includes a portion adjacent to the outer end of the strip having a piece of liner material disposed thereon in order to facilitate removal of the first stamp or group of stamps from the strip.

Abstract: A multi-user meal planner for providing users with an individually customized, daily meal plan is disclosed. The multi-user meal planner includes a user interface and a relational database management system. The database management system includes nutritional information and an algorithm operationally connected to the nutritional information. The database management system further includes user information that is inputted through the user interface. After being inputted through the user interface, the user information is processed by the algorithm. The algorithm generates a meal plan for the user and the database management system transmits the meal plan to the user interface. A method of providing the individualized meal plan is also provided.

Abstract: An integrated and computer controlled printing press, inspection rewinder and die cutter system for manufacturing printed products from a web of material is provided, which generally comprises at least one rotary die cutter, a plurality of cameras, a plurality of networked computers electrically connected to the cameras for inspecting the print registers and the print to cut register of each product, and at least one monitor connected to the networked computers. The system uses an identification code for each product to precisely detect, track and record in a permanent format the defective and non-defective printed products at every stage of the manufacturing process and can also automatically adjust the die cutters to correct the cut to print registration in real time.

Abstract: A system of elements capable of transferring thermal energy from outside to inside a building or vice versa, has abutting waterproof trays (a) enclosing tubes (d) at their junction. Correspondingly long slotted profiles (b) enclosing the joints and held captive by them may be rotated to allow the insertion of rigid elements (c) sequentially so that adjacent pairs of profiles (b) are restrained from further rotational movement and provide a planar surface. Rigid elements (c) of sufficient density may provide a flat roof which is self-ballasting against wind uplift without penetrative fixings to the sub-surface.

Abstract: A biocidal material comprises an organic biocide immobilised on a polymeric support characterised in that the support is water-insoluble and the biocide is covalently bound to the support by a hydrolytically stable covalent linkage. The material can be used for inhibiting bacterial growth in an aqueous medium e.g. the wash water of a photoprocessing system. The material can be housed in a flow-through container.

Abstract: An ion-sensitive calix(4)arene compound having the formula A.sup.2 +B.sup.2 - wherein A represents a cation capable of forming a receptor-substrate complex with an anion, and B represents sulfate, nitrate or borate, characterized in that the cation is an anion receptor represented by the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are each independently a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group wherein substituents are selected from alkyl C(O)NH--, aryl C(O)NH--, alkoxy, aryloxy, alkoxycarbonyl, aryloxycarbonyl, alkylsulfonamido, arylsulfonamido, alkylcarbonyl, alkoxycarbonyl, aryloxycarbonyl, cyano and nitro;R.sup.5 and R.sup.6 are each independently H or a lower alkyl group having from 1 to 4 carbon atoms, or R.sup.3 and R.sup.4 taken together represent an ethylene bridging group; and,n is 0 or 1.

Abstract: A biocidal material comprises a biocide immobilized in a porous inorganic polymer network such as a sol-gel matrix. The polymer may be coated on an inorganic support. The material can be used for inhibiting microbial growth in an aqueous medium, e.g., the wash solution of a photoprocessing system. The material can be housed in a flow-through container.
