Abstract: A method of operating a telecommunications network to provide network-based messaging services includes utilizing a communication link between the network and a telephone adjunct interface. The adjunct interface detects and alerts the subscriber to the existence of waiting messages. In accordance with an illustrative embodiment of the invention, a combination of AC ring detection and outcall polling of the network is employed to determine whether any messages have been received by the network service platform. Specifically, if the subscriber phone is not answered after a predetermined number of rings, the interface polls the network after a suitable delay to determine if any messages were left. If so, the network transmits a code or other signal that is recognized by the interface device, and a visual and/or audible indication is then provided to the subscriber. If the subscriber line is busy or on call-forward while a calling party is seeking to leave a message, the network service platform stores the message and waits a selected interval before seeking to alert the subscriber.

Title: Process for the preparation of polybenzazole filaments and fibres
Inventor: SEN ASHISH
IPC: D01F6/74
Filed: 1995-09-08
Abstract: Described is a continuous process for removing polyphosphoric acid from a polybenzazole dope filament, which comprises: (a) contacting the dope filament with water or a mixture of water and polyphosphoric acid under conditions sufficient to reduce the phosphorous content of the filament to less than 10,000 ppm by weight; and then (b) contacting the dope filament with an aqueous solution of an inorganic base under conditions sufficient to convert at least 50 percent of the polyphosphoric acid groups present in the filament to a salt of the base and the acid. It has been discovered that contacting the dope filament with a solution of a base after washing the filament to remove most of the residual phosphorous advantageously leads to an improvement in the initial tensile strength of the filament, as well as improved retention of tensile strength and/or molecular weight (of the polybenzazole polymer) following exposure to light and/or high temperatures.

Inventor: GAGNON ANDRE
IPC: G08B13/24
Filed: 1997-06-06
Abstract: In an intrusion detection system of the kind which comprises a "leaky cable" or open transmission line and is used to determine the presence of objects, things or people moving in the vicinity of the leaky cable, a transmitting antenna and a receiving antenna, one of which is a leaky cable, and connected to a transmitter unit and a receiver unit, respectively. A control unit controls both the transmitter and the receiver, and causes the receiver to scan a preselected radio band, with the transmitter not transmitting, to detect one or more relatively quiet portions of the band in which instant received signal levels are lower than a predetermined threshold. The control unit selects a plurality of disparate frequencies in such one or more relatively quiet portions and subsequently causes the transmitter to transmit signals by way of the transmitting antenna at the disparate frequencies. The receiver unit receives signals corresponding to the transmitted signals and the control unit detects perturbations in the received signals caused by an intruder in the vicinity of the leaky cable to determine the presence of an intruder. The disparate frequencies may have a bandwidth equal to at least 5 per cent and preferably about 10 per cent of their mean frequency. Operation in the quiet bands allows frequency diversity to be employed, reducing the effects of standing waves and allowing the leaky cable to be deployed without a surrounding electrically-lossy medium, for example above ground, while providing uniform detection sensitivity.
