Patent CA-2230876-A1 (CA)
Title: Ceramic envelope device, lamp with such a device and method of manufacturing such a device
Inventor: JUENGST STEFAN
IPC: H01J61/82
Filed: 1998-02-26
Abstract: This invention involves a new type of feedthrough-plug member for metal halide HID lamp using PCA envelopes. The construction of the lamp housing consists of a PCA envelope and specially designed radially graded alumina-metal cermet multilayers to eliminate cracking in cermet or PCA due to thermal stresses arising from thermal expansion mismatch. The fills are metal halides such as Na-Sc-I, rare earth halides, Hg, Sn, and inert gases. The PCA vessel and directly sealed cermet-feedthrough assemblies allow the metal halide lamps to operate at high wall temperatures with better lumen output, color temperature, and CRI.
Patent CA-2233133-A1 (CA)
Title: Ready-to-wire circuit breaker
Inventor: HUDSON RICHARD H II
IPC: H01H71/08
Filed: 1998-03-25
Abstract: A circuit breaker terminal (18) has an attachment screw (20) pre-assembled to an "open position" enabling an installer to insert a wire without having to loosen and back out the screw. After a wire has been inserted, the installer tightens the screw into forceful engagement with the wire to secure the wire to the load terminal. The attachment screw shank (20s) has an irregularity (38) that is located along a segment of the screw thread that lies between proximal and distal ends of the screw thread (34) and that interrupts the uniformity of the screw thread. This irregularity is disposed in interaction with a through-hole (28) in the terminal when the screw is in open position to create a resistance to turning of the screw which sufficiently exceeds the resistance to turning encountered when a portion of the screw thread immediately contiguous the irregularity is threaded into the through-hole. The irregularity maintains its interactivity with the through-hole to keep the screw in open position until the screw is turned by an installer at time of installation.
Patent CA-2233917-A1 (CA)
Title: Therapeutic administration of hemoglobin in cardiac arrest
Inventor: CHOW MOSES S S
IPC: A61P9/00
Filed: 1996-08-20
Abstract: Administration of stroma-free cross-linked hemoglobin during standard cardiac pulmonary resuscitation procedures enhances return of spontaneous circulation following electrical defibrillation. The difficulty in restoring spontaneous circulation directly correlates with a generally poor prognosis in cases of cardiac arrest. The therapeutic effect of hemoglobin as an adjunct to conventional treatment may thereby improve survival.

Patent CA-2239152-A1 (CA)
Inventor: RAMFELT LARS
IPC: H04J3/00
Filed: 1996-12-23
Abstract: The present invention relates to a defragmentation method and arrangement for increasement of the average block size of free tokens in the nodes of a DTM  (Dynamic Synchronous Transfer Mode) network. The defragmentation comprises defining a home node for each token at network startup in such a way that the tokens sharing the same home node will always define at least partly a continuous slot range, sending back free tokens to home nodes when a significant time has passed and, merging two or more slot-consecutive tokens with the same slot range into a single token when existing in the free pool of a node. The defragmentation can be realized in a central or a distributed token management scheme.

Patent CA-2241924-A1 (CA)
Inventor: CERAMI ANTHONY
IPC: C07K14/415
Filed: 1996-12-23
Abstract: Methods are disclosed for measuring the accumulation of advanced glycosylation endproducts (AGEs), and for lowering the accumulation of advanced glycosylation endproducts, which are predicated on the discovery that such AGEs and their precedent glycotoxins are present in tobacco and its byproducts. More particularly the methods focus on the observation that individuals who smoke or otherwise use tobacco have increased levels of AGEs relative to non-smoking individuals. The present methods relate to the measurement of AGE levels in both individuals and in tobacco and its byproduct, smoke, and to the treatment of such individuals with agents capable of reacting with glycosylation products to either avert or diminish the accretion of AGEs in the body. Methods are also disclosed for the evaluation of the tobacco products to determine their storage status and organoleptic capacity and potential, for the treatment of the ambient atmosphere to lower AGE levels, and for the treatment of the tobacco products and combustion byproducts to lower AGE levels therein. For example, air or other samples may be taken and evaluated by a dosimeter or like device, to determine whether AGE levels exceed normal, after which measures could be implemented to remediate the ambient condition. Likewise, filters and similar devices for removing AGEs from tobacco smoke are disclosed. All such methods and corresponding materials are contemplated and included.

Abstract: A telecommunications management network (TMN) (32) is directly connected for operation and maintenance data message exchange to a common channel signaling network (12). The direct connection to the telecommunications management network is made through a gateway one (18 1) of a plurality of signal transfer points (18) included within the telecommunications network (10). Addressing and format conversions are effectuated between the transmission control protocol/Internet protocol (TCP/IP) used for the telecommunications management network operation and maintenance messages and the common channel signaling - signaling system No. 7 messages. The telecommunications management network and each of the network element nodes are accordingly assigned both an Internet protocol address and a signaling system No. 7 (SS7) address. Static tables (44) maintained in certain ones of the signal transfer points map Internet protocol addresses and signaling system No. 7 (SS7) address against each other for message routing.

Filed: 1998-06-05
Abstract: An improved DC compensation method for use in conjunction with telephony signalling. The method includes defining a frame that includes at least two n-bit codewords. An unsigned codeword is then identified within the frame by applying a rule to the codewords in the defined frame. Next, a sign bit is appended to the unsigned codeword, thereby producing a DC compensating codeword. The sign bit is selected based upon a weighting function of the linear values associated with previously transmitted codewords. The remaining unsigned codewords in the frame are assigned sign bits from user data.
