Abstract: A check valve connectable in a refrigerant line is economically fabricated from only four parts - (1) a copper tubing body connectable in the refrigerant line,  (2)  a nonmetallic shutoff ball, (3) an annular valve seat member having  a  diametrically  opposite  pair  of  leg  portions axially projecting from one end thereof, and (4) an annular stop member also having a diametrically opposite pair of leg portions axially projecting from one end thereof, and further having a diametrically opposite pair of axially extending outer side surface grooves formed therein.  The seat and stop members are locked together to form a cage structure by axially press-fitting the valve seat member outer leg ends into the stop member grooves in a manner such that the stop member legs underlie and support the seat member legs, with outer ends of the stop member legs facing a conical seating surface of the seat member in an axially spaced relationship therewith.  The shutoff ball is captively retained laterally between the seat member legs for axial movement within the cage structure between an open position in which the ball seals against the seating surface, and an open position in which the ball is axially moved away from the seating surface and is stopped by the outer ends of the stop member legs.  The cage is coaxially and captively retained in a longitudinally central portion of the copper tubing body between two elongated, spun-down, reduced diameter end portions thereof that may be soldered into a refrigerant line.

Granted: 2002-05-21
Abstract: In a communication system, a source node responds to a packet by transmitting a signaling message to an ATM network, containing source and destination network-layer addresses and source and destination transport-layer addresses of the packet. The ATM network includes a filtering table having a plurality of entries each storing source and destination network-layer addresses and source and destination transport-layer addresses. Upon receipt of the signaling message, the ATM network returns a grant indication message to the source node if contents of the received signaling message are identical to contents of one of the entries of the filtering table, and establishes a virtual connection between the source node and a destination node. The source node is responsive to the grant indication message for storing the network-layer addresses and transport-layer addresses of the received packet into a virtual connection management table, segments a subsequently received packet into cells and transmits the cells over the virtual connection if the packet contains addresses identical to the addresses stored in the virtual connection management table.

Abstract: L'invention concerne un procédé et un dispositif permettant de produire une séquence de caractères à contrôle de transition et à équilibrage du courant continu à partir d'une séquence d'entrée d'octets de données. Dans chaque octet, les bits sont complémentés sélectivement en fonction du nombre de signaux logiques "1" afin de produire des blocs de données sélectivement complémentés. Une disparité cumulative est ensuite déterminée entre les valeurs logiques de type différent comprises dans certains blocs sélectivement complémentés déjà codés en caractères. Une disparité courante dans un caractère candidat associé à un des blocs de données sélectivement complémentés courants en train d'être codé est également déterminée. Le caractère candidat est assigné au bloc de données courant si la disparité courante est d'une polarité opposée à une première polarité de la disparité cumulative. Le complément du caractère candidat peut également être assigné au bloc de données courant si la disparité courante est de la première polarité. Dans un mode de fonctionnement à transition élevée, les bits contenus dans les blocs de données contenant moins qu'un nombre minimum de signaux logiques "1" sont complémentés sélectivement, de façon que chaque bloc ainsi complémenté contienne plus que le nombre minimum de transitions logiques. Dans un mode de fonctionnement à transition basse, les bits contenus dans les blocs de données ayant plus d'un nombre prédéfini de signaux logiques 1 sont complémentés sélectivement, de façon que chaque bloc ainsi complémenté contienne moins que le nombre maximum de transitions logiques.

Granted: 2002-03-26
Abstract: A coaxial drop cable safety device is used for cable television, data and telephony applications. The device is used on buried drop cable where 60 Hz powering voltages applied to the drop cable exceed low voltage safety limits and where the drop cable is buried at depths which is less than the minimum required to meet electrical safety codes. Tap end and premise end units are connected to the drop cable. The tap end unit applies a DC voltage to the center conductor of the drop cable. A monitoring circuit in the tap end unit monitors the center conductor DC voltage to a fault from the center conductor to ground along the drop cable.  The tap unit will immediately remove the powering voltage In the event of either an open or faulted condition on the center conductor along the entire length of the drop cable. Additionally, while providing fault protection for the low frequency powering circuit due to tampering or damage to the cable, the fault monitoring circuit allows the high frequency television, data and telephony signals to pass with little or no impediment.

Granted: 2006-11-21
Abstract: Transversely stretchable elastic laminated fabric with cloth-like facings was made by a two-step process. In the first step an inelastic laminate was made by continuously extruding an elastomer sheet between two plies of a fibrous sheet and joining the plies by applying pressure on them between a closed gap niproll assembly.      Two longitudinal slits were made into the laminate. Then the rolls of inelastic laminate so made were taken to an oven and the laminate was unwound and pulled through the oven at an elevated temperature, while tension on the web was increased until the slits necked. The necked laminate was wound up on a takeup roll.      When samples were unwound, surprinsingly they did not grow in width, and they showed good CD-elasticity (elongation and springback). Breathability of the laminate was superior to the laminate formed using an open niproll assembly gap.
