Abstract: Le systeme fonctionne en s'adaptant aux besoins du trafic. Il peut faire une distinction entre une demande de routine et une demande prioritaire. Le systeme se compose essentiellement d'un micro-ordinateur forme par une unite de traitement central (3), par une memoire de programme (4) et par une banque de donnees, tous ces dispositifs recevant des parametres de commande par l'intermediaire d'un systeme d'entree a clavier (7) ou un systeme de transmission de donnees (8). Le systeme est tres flexible pour coordonner le trafic urbain dans la mesure ou il peut etre adapte aux differents plans et horaires du trafic par l'intermediaire d'une memoire de programme (4) et des elements peripheriques. Il peut fonctionner centralement, simplement par l'installation d'un systeme de communication entre le systeme central et un systeme de commande local. Ceci permet l'application d'un plan de controle du trafic par zones. En fonctionnement pendant des periodes de trafic de faible densite, le systeme donne la priorite avec un minimum d'attente par l'intermediaire de l'unite de traitement central, l'assemblage de phases, et l'interface de module de phases (6). Il permet de plus la synchronisation entre plusieurs systemes de commande identiques par l'intermediaire d'une horloge synchronisee externe sans qu'elle soit connectee physiquement au systeme de commande.

Title: Moulage par soufflage sans presse
Inventor: ELGNER ROGER
IPC: B29C49/32
Filed: 2003-02-11
Abstract: Un moule destiné au moulage par soufflage possède un premier (12) et un second bâti (14). Ces bâtis (12, 14) correspondent à des demi moules ou des parties de moule classiques. Ce premier bâti (12) comprend un organe de commande (40), habituellement sous forme de pitons (46), alors que le second bâti de moule possède un organe de commande de réception (66), habituellement sous la forme de trous (70), destinés à recevoir les pitons (46). Lorsque le second bâti (14) de moule est en registre avec le premier bâti (12) de moule, les pitons (46) ou d'autres organes de commande (40) sont déployés de façon à verrouiller ensemble et à mettre en place les deux bâtis (12, 14). Le moulage par soufflage peut ensuite être effectué sans qu'il soit nécessaire de recourir aux presses de moulage par soufflage habituelles. Un procédé de soufflage consiste à utiliser un bras robot (84) pour déplacer le second bâti (14) de moule relativement léger susmentionné en dessous d'une tête d'extrudeuse (102) de façon à accepter une paraison lorsque celle-ci est extrudée, et cette paraison est ainsi contenue dans la cavité (60) du moule. Après cette extrusion, le bras (84) déplace le second bâti (14) de moule vers le premier bâti de sorte que ces bâtis puissent être mis en place et verrouillés ensemble. Un seul robot (110) utilisant une seule tête d'extrudeuse (102) peut servir plusieurs stations de moule dépendant de durées de cycle.

Patent CA-2006247-A1 (CA)
IPC: H02J13/00
Filed: 1989-12-20
Abstract: Abstract of the Disclosure Outbound signals carried over an electric power network are detected and crosstalk is rejected by sampling the waveform in three segments of each cycle.  In the first segment valid signals are always absent.  Valid signals appear at the same time in both the second and third segments.  Sample waveform values from alternate half cycles are compared to detect differences indicative of outbound signal information.  The energy in each of the three segments is compared with an energy threshold for that segment and a cycle under test is rejected when the energy in the first segment exceeds the threshold for that first segment.  A cycle under test is also rejected if the energy in the third segment greatly exceeds the energy in the second segment.  Signal detection thresholds for both signal strength and energy in the segments are set recursively using actual samples acquired at the outbound detection site.  These thresholds are sensitive to dynamic network changes.

Inventor: HAHN CARL J III
IPC: H01Q3/24
Filed: 1990-03-22
Abstract: A transponder (10) that selectively provides both global and spot beam antenna coverage. The transponder (10) comprises a channel amplifier (12) and an antennafeed network (18) that includes coupler means (20) for coupling energy into a plurality of power distribution networks (21, 22) that feed a plurality of antenna radiating elements that form a beam that illumates the desired coverage area. A variable power divider (13) is coupled to the amplifier (12) that variably couples power along two channel output paths. Each output path includes a matched bandpass filter (14, 16) and the second output path includes a phase delay circuit (15). Selective control of the ratio of the power coupled to the respective output paths, and the phase delay provided by the phase delay circuit (15), provides for selective coupling of the total power provided by the channel amplifier (12) to either the full set (26), or a selected subset (25) of the antenna elements which generates global and spot beams, respectively. A more complex version is described which additionally incorporates an N-channel multiplexer (30). The present invention may also be employed as an interface circuit that may be interposed between a transponder channel amplifier (12) and an antenna feed network (18) to retrofit existing transponders to provide for selectable beam coverage.

Abstract: A drum brake assembly including a brake member comprised of a substantially circular shoe having a radially outer face on which at least one lining is mounted. The shoe is made from a high strength resilient material and is of substantially constant cross-section along its entire length. The brake member is arranged to be diametrically expanded by actuation means on the brake assembly. When the actuation means is released the resilience of the shoe material causes the shoe to diametrically contract. The lining may be machined to a circular form prior to the brake member being fitted to the brake assembly, and that machining is preferably done after the shoe has been expanded a predetermined extent. The invention extends to a method of manufacturing a brake member. and to a brake member for a drum brake assembly.
