Patent CA-2439141-A1 (CA)
Inventor: FRIEDRICH CHRISTIAN
IPC: H05B3/74
Filed: 2002-02-19
Abstract: The invention relates to a ceramic hob (10) comprising a glass ceramic or glass hot plate (12), an electrical heat-conductive layer (20) and a thermally injected insulating layer (16) between the hot plate (12) and the heat-conductive layer (20). A primer layer (14) that may consist for example of Al2O3, is first applied to the underside of the hot plate (12) by thermal injection and then the thermally injected insulating layer (16) from ceramics, preferably cordierite or mullite is applied. A heat-conductive layer (18) that consists for example of a meandering heat-conductive (20) is applied to the underside of the thermally injected insulating layer (16) preferably by thermal injection. A laminar structure of that kind allows for high thermal stress resistance and good long-term stability of the ceramic hob (10).

Title: Recursive query for communications network data
Inventor: MCMURRY KATHLEEN A
IPC: H04L12/56
Filed: 2002-03-20
Abstract: An approach for providing telephony and other services over a data network is disclosed. A communications system (100) includes a location server (115) that generates a first subset from the set of all addresses relating to a called party (118). A proxy server (113) obtains a first subset of addresses from the location server (115) and attempts to establish a session with the called party (118) based on the subset of addresses. In response to whether the first subset of addresses results in session establishment, the proxy server (113) may then request a second subset from the location server (115). Context information provided by the location server (115) with the first subset may be returned to the location server (115) as part of the request for the second subset.

Abstract: A packer fluid is provided for use with a wellbore fluid in an annulus or casing bore, having an aqueous portion which contains additives for preventing corrosion, microbiological activity, salt and scale deposition, and an environmentally-acceptable capping fluid which resides at a top of the wellbore to act as freeze protection and as thermal insulation in a the frost penetration layer. The additives in the packer fluid are particularly selected to exist in the aqueous additive fluid and in the wellbore fluid and to be substantially immiscible with the capping fluid and thereby prevent significant migration of the additives into the capping fluid which would compromise its environmental acceptability.

Title: Surgical stapling instrument having a spent cartridge lockout
Inventor: SHELTON FREDERICK E IV
IPC: A61B17/072
Filed: 2004-05-20
Abstract: A surgical instrument for laparoscopic and endoscopic clinical procedures simultaneously severs and staples tissue clamped in an end effector comprising an elongate channel, which holds a staple cartridge, and a pivotally attached anvil. An E-beam firing bar engages the channel and selectively engages the anvil during distal firing movements, wherein the tissue is severed and stapled driven upward from the staple cartridge to form against the anvil. In particular, a wedge integral to the staple cartridge is driven distally by a middle pin of the firing bar to effect stapling. A lockout mechanism of the staple cartridge responds to the presence of the wedge sled in its unfired position to allow the firing bar to fire. Otherwise, the lockout mechanism prevents firing when the staple cartridge is spent.
