Abstract: A portable communication unit that operates based upon predetermined discrete blocks of airtime. The unit may be operated as a conventional portable communication unit when airtime is available, and operation of the unit for conventional communication is disabled when all the airtime has been used. By entering a specific code, which may be supplied by a dealer, the user may activate an additional block of airtime. Two classes of airtime may be provided; home time airtime which is used when the unit is within the area of a local or primary communication service provider, and roam time airtime which is used when the unit is outside of the area of a local or primary communication service provider. The unit may be programmed, preferably only by the dealer, with toll restrictor codes that limit the available range of numbers with which the unit may initiate a communication session.

Abstract: Porous polyolefins are especially efficiently free-radically grafted using (fluorinated alkyl)olefins, vinylsilanes or certain carboxylic acids or their esters as the grafting molecules. The use of a solvent to swell the porous polyolefin is sometimes advantageous.

Abstract: Disclosed are compositions prepared by free-radical-driven grafting onto hydrocarbons or hydrocarbon ethers of olefinically unsaturated fluorocarbons containing sulfonyl fluoride, fluorosulfonate, fluorosulfonimide, or fluorosulfonyl methide groups, wherein the grafting step is followed by a hydrolysis step in the case of sulfonyl fluoride.

Abstract: Children's game structure having two modular parts (1) and (2), of an arbitrary number which combine to form a number of ogival arches (5) (5a) (5b) (5c) and which are joined together in line one after the other simulating the rings of a centipede and configuring a tunnel fitted at both ends with flat, vertical parts (17) and (18) representing the centipede's head and tail, with openings (19) and (20) for the children to enter and exit the centipede. The game structure is applicable for children's games of the type that allow the children to crawl through the inside or on top of the outside of the tunnel and the structure is easy to assemble and disassemble for storage as it only requires a small amount of storage space and no tools.

Abstract: A machine for dispensing publications one by one having (a) housing defining an enclosed interior; (b) having an exit opening for dispensing the publications; (c) a platform for receiving a stack of the publications, the platform being supported within the housing for vertical movement between a plurality of positions; (d) a slider which, in an operating mode of the machine, is horizontally movable between fore and aft positions; the slider being disposed within the housing for contacting a topmost publication of the stack with the platform in one of the plurality of positions and for feeding the contacted publication to the exit opening when the slider is moved horizontally; (e) a coin operated mechanism for placing the machine into the operating mode, and (f) a mechanism disposed within the housing for automatically imparting a motion to the slider that pushes the slider against a rear edge of the topmost publication so as to move the topmost publication from the stack to the exit opening when the machine i

Abstract: Improvements in the form of articulated structures for dolls or puppet bodies are disclosed. The improvements include a structure or skeleton-like framework in which the various elements and members which comprise it are connected with one another at their ends by link connections which in combination with the structure of the referenced ends constitute ball and socket articulations. The link connections are formed by two spheres 8a connected by a radial appendix 8b, over which is injected the integrating material making up the semispherical catches 9, constructed in the ends of the elements or members of the skeleton-like framework. The improvements are applicable in the manfuacture of articulated structures for dolls which permit stable and voluntary positioning of their members or connecting parts.

Abstract: A modular structure for constructing houses is designed for children to play. The structure includes moulded material panels which are connected with the assistance of corner parts through conjugated members built into the panels. The panels have an outer embossed surface resembling stonework, windows and door openings in which the relevant leaves or panes are articulated. The facade parts form a top angle for supporting saddle roof parts above. The modular structure is used for mounting houses for children to play within and it is accessible for children. The house may also have auxiliary rotatable simulated domestic elements, such as a vertical mirror that rotates down to be a horizontal table top.

Abstract: A modular construction for children to play. It consists of two side parts (1) forming two ladders, connected at the bottom and top ends by a part (11) forming a seat, and by a roof-like part (7) with a handrail (8), a slide having two sections (13) and (14) extending from such roof to the supporting plane. The invention is applicable for constructions based on modular parts made of a hard plastic material, which include conjugated connectors integrated therein.

Abstract: A mountable toy for children comprising four modular facade parts (1) and two modular roof parts (2) of a moulded material, the parts (1) making contact through their upright sides, at joints (24) on either side of which there are holes (5) facing holes (4) in plates (3) lying over the joints (24). Parts (2) have holes (11) matching holes (10) at the ends of strips (9) which cross over the resulting joint (23). Parts (1) are provided with spherical heads (14) at their top which are housed in cavities (15) in parts (2), establishing a connection between the facade and the roof structures. The facade parts and roof parts embody a particular configuration which resembles a caricature, such as a mushroom.

Abstract: A method of configuring an artificial neural network for predicting residual chlorine concentration in water contained in a storage tank of a water supply system, the storage tank having an inlet for admitting water into the tank and an outlet for discharging water from the tank. The method of the invention comprises the steps of (a) collecting historical data representative of selected operational and water quality parameters associated with chlorine demand in the tank; (b) scaling the data collected in step (a); (c) organizing the data scaled in step (b) in the form of a set of time-lagged data; and (d) processing the data organized in step (c) through an artificial neural network by scanning a window over the set of data, the window having a size corresponding to a sub-set of the data, to associate a predicted value with a respective one of the sub-sets scanned by the window, the predicted value being representative of the residual chlorine concentration at the tank outlet.

Abstract: Apparatus for spin closing an open end of a tube of a suspension strut comprising a throughbore having a longitudinal axis; a first pair of rollers, each roller of the first pair being rotatably mounted in a bore opening into the throughbore, having a contact surface at a first predetermined angle to the longitudinal axis and which extends into the throughbore, and being biased such that the contact surface can retract from the throughbore against the action of biasing means; and a second pair of rollers, each roller of the second pair being rotatably mounted in a bore opening into the throughbore, and having a contact surface at a second predetermined angle to the longitudinal axis and which extends into the throughbore; wherein the second predetermined angle is greater than the first predetermined angle; and wherein the first pair of rollers is offset from the second pair of rollers along the longitudinal axis such that, on insertion, the open end of the tube of the suspension strut will make contact with t
