Patent CA-2034196-A1 (CA)
Title: Vulcanizable liquid compositions
Inventor: COOLBAUGH THOMAS S
IPC: C08F8/04
Filed: 1991-01-15
Abstract: There is disclosed a linear block copolymer comprising at least one triblock I-B-I, wherein I is a block of at least one polymerized conjugated diene of at least five (5) carbon atoms, such as isoprene, and B is a block of a polymer of at least one conjugated diene, different from that used to polymerize the block I, of at least four (4) carbon atoms, such as 1,3-butadiene. The B block is selectively hydrogenated, while each of the I blocks is unhydrogenated and therefore retains a sufficient amount of its original unsaturation to vulcanize the copolymer. There is also disclosed an alternative linear block copolymer containing at least one triblock of the first polymer block made from a minor proportion of at least one aryl-substituted olefin, such as styrene, and a major proportion of at least one conjugated diene used to polymerize the block I, the second middle polymer block of at least one diene used to polymerize the block B, and the third polymer block which is the same as the first polymer block. In this alternative copolymer, the middle block is also selectively hydrogenated, thereby leaving the terminal polymer blocks with a sufficient amount of their original unsaturation to vulcanize the copolymer. The polymers can be crosslinked or functionalized through the terminal block containing the vinyl unsaturation. There are also disclosed random linear and star-branched block and random copolymers made from the same monomers as the linear block copolymers.      Also disclosed are methods of producing the polymers and selectively hydrogenating the aforementioned polymerized dienes.

Abstract: Architecture améliorée d'interface réseau pour commutateur/commutateur rapide de paquets. Cette architecture d'interface réseau permet la combinaison de la voix et des données grâce à un seul commutateur à l'aide d'une structure commune de paquets. Cela permet une répartition dynamique de la largeur de bande en fonction du chargement du système. Cela comporte non seulement la largeur de bande comprise dans la zone de voix ou dans la zone de données de la trame, mais aussi celle entre la partie voix et la partie données. Dans l'interface réseau (IR), un moyen (Bus-IR) permet la transmission de tous les paquets par l'entremise de l'interface réseau ou l'échange direct de paquets entre les dispositifs de commutation des paquets. La largeur de bande attribuée peut facilement être modifiée parce que la mémoire de commande et la mémoire de données sont synchronisées. L'architecture d'interface réseau, grâce à la présente invention, permet la commutation des paquets de données et l'attribution de la largeur de bande à l'aide d'un seul dispositif de commutation. La présente invention permet la synchronisation du transfert des données et l'attribution de la largeur de bande aux bus. Le contrôle des dispositifs de commutation des paquets peut s'effectuer selon un débit binaire très élevé, par exemple 400 Mbit/s. L'invention permet également aux dispositifs de commutation des paquets de transférer directement des paquets. Elle permet de réattribuer la largeur de bande grâce à l'utilisation des registres de base de l'interface réseau.

Title: Circuit for adding r.f. signals
Inventor: BURRAGE CLEMENT P
IPC: H04N5/38
Filed: 1991-07-16
Abstract: ABSTRACT           Circuit for Adding r.f.  Signals (Figure 6) The  circuit  is  capable of selectively  adding  r.f. inputs  at  A, B, dependent on the bias voltage  applied  to varactor diodes D1, D2. In one bias condition of the diodes and hence  one value of capacitance, the reactance between A and B and  between  the output and point D is equal  to  the reactance  of  transmission lines 10, 11 formed by  co-axial cables,  and  quadrature inputs at A and B are  combined  at output O/p.  At another value of capacitance of the varactor diodes,   corresponding  to  another   bias   voltage,   the capacitance of the diodes and the series capacitances C1, C2 resonate  with  the  inductances  L1,  L2  and  input  A  is effectively isolated from input B.     The  circuit can be used to produce a power  amplified composite  video r.f.  signal, input A being connected to  a power amplifier  for the video signal only and input B being connected  to  a pulse amplifier for the sync  pulses  only.   This permits  more efficient use of the amplifiers  compared to a single  amplifier  for amplifying the  composite  video signal.

Title: Apparatus for communicating between systems having different communications standards
Inventor: LONGSDORF RANDY J
IPC: G05B19/418
Filed: 1991-07-19
Abstract: ABSTRACT OF THE DISCLOSURE           The communicator made according to the present invention receives queries from a process controller and directs  them  to  their  intended  destination  after formatting them appropriately.          The received query contains a process variable (PV) address section.   A storage section stores the PV address, which is representative of a storage location for a process variable in a field device (FD).  The FD is in a network of FDs where each FD has an FD type and a unique FD  address.    In  an associating  section,  each  of  a plurality of FD addresses and the FD type corresponding to such  FD  address  are  associated with  one  PV  address corresponding thereto and an output is provided which is representative  of  a  corresponding  address  pair.    An extracting section receives the stored PV address from the storing  means  and  accesses  the  associating  means, searching through the address pairs and extracting an output  containing  the  FD  address  and the  FD  type corresponding to a PV address which matches the stored PV address.   Finally,  a generating section receives the extracted FD address  and FD type and generates  a FD request as a function of the PD type and containing the extracted FD address.  The FD request is conveyed over a line common to the FDs, to the FD containing the stored PV address location.          The storage section includes an IEEE serial interface for coupling to the process controller.   In a preferred embodiment, the IEEE serial interface can be RS-232, RS-422 or RS-485.  In another embodiment, the storage section  includes  two  IEEE  serial  interfaces,  either couplable to the process controller.  The storage section also has a bidirectional echoing section coupled between the IEEE serial interfaces for echoing a query received on one interface to the other interface.
