Patent CA-2182363-A1 (CA)
Title: Formules de resine a matrice adaptee par des methodes chimiorheologiques, contenant des agents de polymerisation anhydrides
Inventor: MUMFORD NEAL A
IPC: B29B15/10
Filed: 1995-02-13
Abstract: L'invention décrit des formules de résine dont la viscosité de la matrice est adaptée par des méthodes chimiorhéologiques, utilisées pour former des articles préimprégnés et composites. Ces formulations ont un profil de viscosité précis, obtenu à partir d'une matrice polymérisable et d'une quantité efficace d'un agent de polymérisation de la résine réactif à température ambiante et d'un agent de polymérisation de la résine latent sensiblement inerte à température ambiante. L'agent de polymérisation de la résine latent est activé par la chaleur ou par un rayonnement. La formule de la matrice de résine est adaptée lors de la formulation de façon à obtenir une viscosité suffisamment faible pour permettre l'imprégnation de fibres ou de plaques par la résine de la matrice à température ambiante sans qu'il soit nécessaire d'appliquer de la chaleur ou un solvant, laquelle viscosité augmente lors d'un séjour à température ambiante après imprégnation des fibres ou plaques pour former un préimprégné. La viscosité de la résine de matrice du préimprégné diminue au chauffage jusqu'à une viscosité minimale suffisamment basse pour que la résine de la matrice puisse couler et éliminer sensiblement les vides dans l'article composite formé dudit préimprégné, mais pas suffisamment basse pour qu'il se produise une fuite excessive de la résine de la matrice hors du préimprégné. Si le chauffage se poursuit, la résine de la matrice polymérise dans un état durci ou gélifié.

Title: Two stage clock dejitter circuit for regenerating an e4 telecommunications signal from the data component of an sts-3c signal
Inventor: UPP DANIEL C
IPC: H04J3/07
Filed: 1995-06-30
Abstract: A two stage desynchronizer (10) is provided to receive a gapped data component of an STS-3C(STM-1) signal and provide therefrom an ungapped DS-4NA (E4) data signal. The first stage (10a) includes a data byte formation block which takes the gapped STS-3C payload data and formulates the data into bytes, a first FIFO (25) which receives the bytes, and a first FIFO read controller (30) which utilizes the STS-3C clock signal and causes bytes of data to be read out according to a schedule which reads bytes eight or nine times out of every ten STS-3C clock cycles. For each row (270 byte times) of the STS-3C frame, either 241 or 242 bytes are read out of the FIFO according to a slightly gapped schedule where the reading of the 242nd byte at least partially depends upon the number of stuffs in the signal and the pointer movements received. The second stage (10b) of the desynchronizer (10) includes a second FIFO (50), a second FIFO fullness measurement block (60), and a VCXO (80). The second FIFO fullness measurement block (60) uses the incoming slightly gapped byte clock and the ungapped DS-4NA output clock as inputs for effectively measuring the relative fullness of the second FIFO (50), and provides a control signal based on the relative fullness.

IPC: G07B15/00
Filed: 1997-01-10
Abstract: A mobile terminal (20) for mobile communication transmits a radio signal carrying a terminal number and a particular dial number. Each toll lane (12) of a tollgate is provided with an antenna (121) for receiving the radio signal and a vehicle's class detector (122) for detecting the vehicle's class of an automotive vehicle (11). Each tollgate is provided with a terminal information receiving unit (13) and an interface circuit (16). Responsive to the radio signal from the antenna (121), the interface circuit (16) identifies as lane information an entry lane which the automotive vehicle (11) is entering and acquires terminal information corresponding to the terminal number by accessing the mobile communication exchange system (30). The terminal information receiving unit (13) receives the lane information and the terminal information for transmission to a data memory unit (14). On the other hand, the processing unit (17) acquires vehicle's class information from the vehicle's class detector (122). The processing unit (17) then prepares and stores in the data memory unit (14) passage car information containing the lane information, the terminal information, the vehicle's class information, and a passage time. A central processing computer (15) obtains from every tollgate vehicle passage data including the passage vehicle information and tollgate information to prepare toll charge data.
