Patent CA-2220911-A1 (CA)
Title: Code division switching scheme
Inventor: SHERMAN MATTHEW J
IPC: H04B1/707
Filed: 1997-11-12
Abstract: Each user signal of a communications network is encoded using a narrowband traffic code and a wideband cover code for transmission to a signal relay (e.g., a communications satellite) in one of a plurality of uplink signal beams. The sign al relay receives all of the user signals in the different uplink signal beams and proces ses them to re-transmit them in different downlink signal beams to their different approp riate destinations. The narrowband traffic codes and wideband cover codes are selected to encode the individual user signals in such a way as to permit the switching proc essing of the signal relay to be implemented at the beam level (e.g., individual compon ents processing multiple user signals at a time) rather than at the user level (e.g., one switching circuit for each user). For example, in one embodiment, all user signa ls within the same signal beam are encoded using different narrowband codes and the same wideband cover code, while user signals in different signal beams are encod ed using different wideband cover codes. The present invention enables a reduction in the volume and cost of switching equipment within the signal relay. Furthermore, muc h of the switching processing can be implemented at intermediate frequencies (IF) usi ng conventional, relatively inexpensive radio frequency (RF) components.

Title: Adapting the fixed network protocols to a mobile communications network
Inventor: R S NEN JUHA
IPC: H04W92/02
Filed: 1996-11-06
Abstract: The invention relates to an interworking function apparatus (IWF), a method and an arrangement for establishing a mobile-terminating call in a mobile communications network when the call is received from a calling party via a fixed network without any signalling support which provides information on the protocol employed by the calling party. In the invention, a service is assigned only one directory number, which is common to all the protocols employed by the service. The protocol identifier in a service definition linked with this directory number has a neutral (undefined) value or may be interpreted as neutral. The IWF, upon receiving the neutral RA parameter (Step 2), is switched onto the line and monitors a traffic channel received from the fixed network in order to identify the protocol employed by the calling terminal equipment (Steps 54-57). After identifying the protocol, the IWF is configured according to the identified protocol (Steps 58-60 or 61-63), and data transfer may begin (Step 64).

Filed: 1996-12-16
Abstract: A medical valve has a body which includes a wall structure defining an internal cavity having a proximal end and a distal end. The proximal end has an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through the delivery end. The valve also has a spike with a tip contained within the cavity and at least one hole located distal the tip. The spike has a passageway in communication with the hole that allows fluid to flow through the spike. The valve also has a resilient seal in the cavity which surrounds the spike. The seal is adapted to be moved into a compressed state upon insertion of the tip of the medical implement into the opening. The seal is sufficiently resilient to return to a decompressed state upon removal of the tip of the medical implement from the opening. In addition, the seal has at least two tires in contact with the spike proximal the hole, preventing the flow of fluid through the valve when the seal is in the decompressed state.

Patent CA-2262305-A1 (CA)
Inventor: TRACEY MICHAEL E
IPC: F23D14/46
Filed: 1999-02-23
Abstract: A two-step method to porcelain-coat an article is provided particularly useful for porcelain-coating a gas burner used in a gas-fired residential barbecue grill. A gas burner constructed from mild enameling-grade steel is dipped in a slip containing porcelain frit and manipulated so that the slip adequately coats and adheres to the interior surfaces of the burner. The porcelain-containing slip simultaneously coats and adheres to the peripheral "shoulders", and particularly to the interior "shoulders", of the gas jet openings of the burner. A second coating of porcelain-containing slip is then applied, for example, by spraying or other conventional wet application techniques, to the exterior surfaces of the burner. The properties, for example specific gravity, of the porcelain-containing slip of the second wet coating are adjusted for optimal coating properties. Then, the double slip-coated gas burner is fired in a continuous furnace at a peak firing temperature of 1480°F to 1550°F, with a target of 1530°F  ~ 10°F for about ten minutes, which adequately bonds the porcelain to the steel gas burner.
