Title: Arrangement for billing interactive communication services
Inventor: CHEN HOWARD ZEHUA
IPC: H04N7/173
Filed: 1996-08-28
Abstract: Only one or only a few channels are sent at a time from curbside circuitry located in a curbside box (15), via a link (22) such as either a coaxial or a fiber cable, into a customer's home TV set (14) or personal computer. However, many more thana few channels are delivered to the curbside box from a central office (36) or a central bank (37) of paid video-movies to be selected by the customers. The curbside boxserves a multitude of homes, a separate (narrow-band) cable (22) running to each home from the (same) curbside switch. Each channel can be a free radio or free TV channel, a stored or an on-line newspaper pay channel, or a pay TV channel, or a pay-per-view channel. Requests from each TV set in each home (e.g., initiated by means of a hand-held remote control infra-red sending device (11)) can be sent to the curbside circuitry from the home along a link (23) such as a wire or along the same curbside-to-home cable itself. Storage of billing information with respect to each customer is accomplished by means of a billing recorder (19) located in the curbside box. A relatively short link (50) connects this billing recorder to a junction (25) in the link that carries the request signals to the curbside box. The billing recorder has registers that record the history of each customer's requests for access to each channel. The billing recorder is provided with circuitry responsive to remote billing interrogation signals sent by one or more remote billing centers (51, 52). In response to these remotebilling interrogation signals, the billing recorder sends the records of the customers to the remote billing center.

Inventor: TAGAWA ITSUO
IPC: B02C1/02
Filed: 1996-01-26
Abstract: A crusher capable of effectively crushing a building structure, shearing iron reinforcing rods, etc., smashing the crushed scraps into pieces, and collecting and carrying an elongated object. A pair of arms (2a, 2b) are driven to open and close for crushing and shearing the object. A front end of each of the pair of arms is divided into a plurality of fingers to which claws (7a, 7a', 7b) are respectively attached.          Only the central claw (7a') is inwardly directed by a greater angle as compared with the other claws (7a, 7b).  Each arms has a shearing blade (10a, 10b) for shearing an iron reinforcing rod, an iron frame, etc. in the vicinity of the pivoted portion, and also through holes (11) in the central portion. Weight of the arms (2a, 2b) and an arm support (3) are balanced with respect to the central axis of rotation of the arm support (3).         The central claw (7a') gives a concentrated stress to the building structure to cause cracks when the arms (2a, 2b) are closed, thereafter the object is squashed out by all of the claws (7a, 7a', 7b). Concrete scraps are smashed by the central portions of the arms and flow out from the through holes.

Abstract: A method and apparatus for executing a conference call session between parties provides collaboration between nodes having separate conference-bridging capabilities, so that selection from a number of alternativeconnectivity schemes can be based upon bridge-to-bridge negotiation. The selection of a connectivity scheme may be based upon one or more of cost and telecommunication resource availability. Selection may also be based upon stored historical data relating to prior conference calls involving at least one of said parties and/or upon historical data of patterns of node resource availability. A conference bridge includes a user interface, a message interface, a connectivity computation component, a conference bridge manager, and a multimedia exchange component. An input to the connectivity computation component includes a database having tariff table information and resource-demand cycle information. Another input to this component is a load monitor for continuously determining the availability of telecommunication resources. In the preferred embodiment, the method and apparatus allow dynamic reconfiguration of conference call connectivity when a time-dependent condition or a load-dependent condition is detected.

Title: Process and composition for cleaning surfaces
Inventor: GRIFFITHS GILLIAN
IPC: C11D3/30
Filed: 1996-02-07
Abstract: When products comprising aqueous solutions of nonionics or nonionic/solvent systems are sprayed as fine droplets to form a discontinuous film, either less cleaning effort can be used with the same level of product, or the same effort can be used with less product. It is believed that the effect is due to the presence of an increased number of menisci and evaporation of the aqueous liquor or part of any solvent component from the product on the surface, and further believed that this evaporation causes local increases in concentration and/or local turbulence which enhances the cleaning process. Accordingly, a first aspect of the invention provides a packaged, aqueous or solvent-containing, nonionic cleaning composition, in a container provided with a spray jet adapted to deliver the composition to a surface in the form of a spray, characterized in that the dosage applied to the surface by each operation of the spraying apparatus falls in the range 0.15-0.5 ml and the said dose is applied over an area of at least 50 cm2 when the spray is operated 15 cm from the surface. A further aspect of the invention relates to a method using the above-mentionned packaged composition. Preferred compositions have a pH of > 10 and comprises, in admixture with water, nonionic surfactant, solvent, an alkanolamine, buffer/alkali and a polymer.

Filed: 1996-06-08
Abstract: The invention relates to a process and a device for transmitting confidential and authentic connection and/or service information between subscribers' data terminals and one or more exchanges of a digital communication system. As this confidential information is transmitted between a subscriber's terminal and an exchange in plain language, i.e. uncoded, there is the risk that intruders or eavesdroppers may receive this information. It is therefore the aim of the invention to make misuse of the exchange and prejudice to the subscriber by an unauthorised person difficult or even completely impossible. To this end the invention provides a process and a device in which there is at least one first security device at at least one subscriber, there is at least one second security device in the exchange or, alternatively, prior to each exchange there is an additional device in which there is at least one second security device. The first and second security devices can encode and/or decode the subscriber's connection and/or service information and exchange it between them.
