Abstract: A copolymerized polyamide, comprising amide bands formed by an aliphatic diamine with 4 to 14 carbon atoms and terephthalic acid, with the existence ratios of distributed respectively adjacent amide bonds satisfying the following formulae (A) and (B), and with the half-crystallization time satisfying the following formula (C). 0.9 ~ [XY] obs./[XY] calcd. < 1.1 (A) 0.9 ~ [XX] obs./[XX] calcd. < 1.1 (B) wherein X stands for an amide bond formed by an aliphatic diamine with 4 to 14 carbon atoms and terephthalic acid, and Y stands for any other amide bond than X. [XY] refers to the rate at which X and Y are adjacent to each other among all the amide bonds in the polymer structure, and [XX] refers to the rate at which X and X are adjacent to each other among all the amide bonds in the polymer structure. [XY] calcd. and [XX] calcd. are respectively the values of [XY] and [XX] calculated on the assumption that X and Y amide bonds are distributed statistically at random, and [XY] obs. and [XX] obs. are respectively the values of [XY] and [XX] measured from said copolymerized polyamide. 4.4 - 0.1 (Tm - T) ~ log tl/2 < 5.5 - 0.1 (Tm - T) (C) t1/2 is the half-crystallization time (seconds). Tm is the melting point (°C) of the copolymerized polyamide. T is the measuring temperature (°C) of the half-crystallization time.

Title: Technique for use in processing telephone calls
Inventor: EISDORFER JERRY
IPC: H04M3/54
Filed: 1995-10-10
Granted: 2003-08-19
Abstract: A telecommunications carrier other than the carrier of last contact is arranged to a) recognize that the telephone to which a particular call is placed is a disconnected telephone and b) provide different call treatment for the call, e.g., different call handling or different call features or services, as compared to the treatment the telecommunications carrier provides for the same call to the same telephone when it is recognized that the telephone is not disconnected. Advantageously, no effort is wasted in an attempt to complete the telephone call to a disconnected telephone. Such different treatments include 1) simply making no attempt to route the call to the disconnected telephone via the network of last contact, 2) routing the call to a secondary, alternate telephone, and 3) initiating transmission of a page to a pager that is associated with the owner of the disconnected telephone.

Patent CA-2190156-C (CA)
Inventor: SHELDON TODD J
IPC: A61N1/365
Filed: 1996-02-23
Granted: 2001-08-21
Abstract: A method of and apparatus for determining the physical posture of a patient's body, having a superior-inferior body, axis, an anterior posterior body axis and a lateral-medial body axis, in relation to earth's gravitational field. A medical device having first, second and optionally, third DC accelerometers having sensitive axes mounted orthogonally within an implantable housing is adapted to be implanted with the sensitive axes generally aligned with the patient's body axes. Each DC accelerometer generates DC accelerometer signals having characteristic magnitudes and polarities on alignment of the sensitive axis with. against or normal to earth's gravitational field and DC accelerometer signals of varying magnitudes and polarities when not so aligned. Body position may be determined through comparison of the magnitudes and polarities of the DC accelerometer signals with the characteristic magnitudes and polarities. A patient activity signal may also be determined from the frequency of body movements recurring over a time unit effecting magnitude changes in the DC accelerometer signals within a certain range of magnitude and frequency. The activity and body position signals may be stored and or used to monitor and effect the delivery of a therapy to the patient, e,g. by controlling the pacing range of a rate responsive pacemaker.

Title: Hybrid single sideband optical modulator
Inventor: DODDS DAVID E
IPC: H04L27/04
Filed: 1997-02-14
Granted: 2003-07-29
Abstract: Bandwidth reduction methods and apparatus that offset the effects of dispersion on a signal transmitted through an optical fiber. The apparatus and methods employ a generator of modulated optical signals in cascade with a modulator. One of the generator and the modulator may be an optical intensity or amplitude modulator and the other a phase (or frequency) modulator.  With the application of specific  signals,  the cascaded generator and modulator produce an optical signal with reduced energy in one half of the transmission bandwidth. One important benefit in the method is the fact that by exploiting the less obvious spectral  characteristics of  single sideband signals,  a simple modulator design is achieved. All of the designs exploit a method of generating analytic signals via hybrid modulation.

Title: Extracts of shark cartilage, process of production and uses thereof
Inventor: MAES DANIEL H
IPC: A61P17/16
Filed: 1995-10-30
Granted: 2004-08-17
Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, direct anti-tumor proliferating, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a homogenate of cartilage in an aqueous solution, this homogenate being centrifuged and further fractionated to obtain a total extract having molecules of a molecular weight comprised between 0 to 500 KDa. The composition of the liquid extract has then been investigated by different ways. Further fractionation of this extract led to the preliminary characterization of some of its active components. Due to the multiplicity of biological activities of the total liquid extract, it can be used for treating numerous diseases or conditions such as those having components selected from the group consisting of tumor proliferation, angiogenesis, inflammation and collagenolysis. This extract has no offensive effect on normal body functions. Therefore, this shark cartilage extract has a very promising therapeutic value. The process for the obtention of cartilage extracts is simple and efficient. The unexpectedly valuable products obtained by this process are therefore an indication of a new and non-obvious process.
