Title: Polymers for cement dispersing admixtures
Inventor: WIDMER JUERG
IPC: C04B40/00
Filed: 2001-03-21
Abstract: Polymers for cement dispersing admixtures, which show different performing properties in concrete are de-scribed. All polymers are based on a composition of reac-tants, namely a) a poly(acrylic acid), b) a polyalkyleneglycol-monoalkylether and, optionally c) a .alpha.-amino-polyalkylene-glycol-.omega.-alkylether and/or d) a primary or secondary amine.      By keeping the composition of reactants constant and varying only the reaction time, polymers with different properties can easily be achieved. Such polymers are suitable for pre-cast, readymix or for increasing workability over time, just depending on reaction time. Polymers of the invention can be used as single polymer or in polymer blends. For this, the kinetics of the used polymer analogous condensation reaction was intensively studied. Additionally, the benefit of amines as reactant regarding stability and hydrolysis velocity of cleavable side groups was investigated.

Title: Suspension assembly
Inventor: JONES JOHN DORIAN
IPC: B60N2/90
Filed: 1999-08-31
Abstract: A seat suspension assembly, for example for incorporation in the seat frame of a motor vehicle to provide support for upholstery, comprises a platform element or pad formed of side wires (1) between which extend transverse wire s (2) that are anchored to the side wires (1) to form a grid. The platform element is suspended in a seat frame by means of a spring unit comprising a transverse wire (4) formed integrally with tension springs (5). Between the transverse wire (4) and springs (5) of the element are formed bights (6) at a spacing corresponding to that of the wires (1). In use, the bights (6) of th e spring element engage with the side wires (1) and extend around the latter t o hold the springs (5) in positions extending from the sides of the platform element. The spr ings (5) can thus be engaged with the seat frame, during manufacture, in a manner that is less labour intensive than would be the cas e if separate springs (5) were provided for engagement with each side wire (1) .

Title: Signaling system and method for network-based pre-paid wireless telephone service
Inventor: WILHOITE MICHAEL T
IPC: H04M15/00
Filed: 1999-09-13
Abstract: A pre-paid subscriber account system for use with wireless telephone systems is disclosed. The system, which monitors a subscriber's call, deducts the cost of the call from the subscriber's pre-paid account in real-time, warns the subscriber during a call when the account is nearing depletion, and terminates the call when the account is depleted. The system can also prevent the initiation of a new call when the account is depleted. Various options can also apply different charging rates, can charge only when specified criteria are met, or can charge only for calls to/from specified areas or telephone numbers. The system and method uses signaling techniques that will allow the metering or billing of the call, along with any authorization or restrictions, to be done remotely from the actual switching of the call. Call events or chargeable events are transmitted to the pre-paid control system while the communications path of the call is held at the switching system awaiting control information. The identity of the pre-paid service subscriber is established using existing means that currently are used to authenticate the user. The wireless phone user does not have to enter any additional codes or identification to obtain access to the pre-paid service.

Title: Method and apparatus for the processing of a web of material
Inventor: LANDOLT MARKUS
IPC: B41J21/00
Filed: 2001-05-24
Abstract: The beginning of a web material fed to a processing device and stored in the form of a roll on a core is provided with a machine readable code which represents an identification code for the web material as well as property data relevant for the processing of the web material. The identification code and the property data are read in at the beginning of the processing of the web material and only web materials with valid identification code are admitted for processing. The processing device is adjusted to the web material used by way of the read in property data. At termination of the processing, the identification code and the updated property data of the web material are again recorded in machine readable code onto the beginning of the remaining web material so that they are again available for the next processing procedure.  Alternatively, the identification code and the property data can also be stored in a storage element activatable by electromagnetic waves which is mechanically connected with the web material.  In this manner, the use of unintended web material types can be stopped. The manual entry of property data can be obviated and a higher user-friendliness achieved. Furthermore, incorrect manipulations are substantially prevented.

It will permit hearing impaired persons who have difficulty in discriminating dialog over ambient sounds in a theater to clearly hear the dialog and also permit persons who speak a foreign language there will be a choice of language for the closed caption text. The device 105 will either receive its signal information wirelessly or will plug into a connector built into the seat or other nearby structure. Power will either be integral or attached to the device or will also be supplied by a hardwire connection. The device can also be used by attendees of events who suffer from either partial hearing loss or are unable to understand the native language as a means of delivering information about the event.

Inventor: GUSTAVSSON PAR
IPC: H04J13/00
Filed: 1999-12-17
Abstract: Resources are reserved or otherwise allocated in a mobile radio communications system in an efficient and timely fashion. In general, the amount of resources that will likely be necessary to support a connection with a mobile station is predicted before those resources are actually required. More specifically, an unknown value of a dynamic connection parameter, like a number of radio paths likely to be involved in supporting the connection, is predicted. In the handover context, these radio paths might correspond to paths with different base stations (as in hard and soft handover) or to paths with different base station sectors (as in softer handover). The underlying resources are allocated using the predicted connection parameter and may include, for example, data processing and memory hardware resources, software resources, radio resources, etc. The resource allocation may also be established using both a predicted dynamic connection parameter along with one or more static connections parameters that are known at the time the connection is set up.
