Title: Improved telecommunications network
Inventor: ARDON MENACHEM TSUR
IPC: H04Q1/18
Filed: 1996-04-22
Abstract: This invention relates to arrangements for interconnecting a plurality of stand-alone switches by data and communication channels (the latter typically used for communicating voice signals) in such a way as to make the plurality of switches act as if they were one switch. According to one arrangement of the invention, a method of controlling a plurality of associated key telephone stations within a set of the stand-alone switches is disclosed. The method includes the steps of grouping the set of stand-alone switches into a symbiotic network, and transmitting first display control data messages, over the data network, to second ones of the switches connected to the stations to control displays of the stations. The method also includes the steps of transmitting display control messages fromthe second switching systems to the stations based on the receipt of the first message in the switching systems and transmitting, over the data network, a request to the first switches to establish a connection from the line or trunk to the stations. The final step involves establishing a connection from the incoming trunk to thestations. Advantageously, such an arrangement provides a convenient way of achieving the advantages of a giant switch without requiring the capacity of such a switch and without requiring the geographic concentration of traffic necessary to keep the links to a giant switch reasonably short. Advantageously, a virtual symbiotic network provides an economical and flexible solution to the problem ofproviding services such as wide area Centrex.

Title: Gastric-retentive, oral drug dosage forms for the controlled-release of sparingly soluble drugs and insoluble matter
Inventor: LOUIE-HELM JENNY
IPC: A61K9/22
Filed: 1997-09-18
Abstract: Controlled-release oral drug dosage forms that comprise a tablet or capsule containing a plurality of particles of a solid-state drug dispersed in a swellable/erodible polymer, such as poly(ethylene oxide) are described. Once ingested, the tablet or capsule disintegrates to disperse the particles within the stomach where they imbibe water to cause them to swell and promote retention in fed-mode-induced patients. As the gastric-retained dosage form gradually erodes, the drug is released in a controlled manner to the stomach for treatment of local disorders, and to the upper gastrointestinal tract where it becomes available for absorption in a controlled and therapeutic manner. Drug-containing vesicles, such as liposomes or nanoparticles or enteric-coated drug particles, can also be delivered to the gastrointestinal tract in a controlled manner using the gastric-retentive dosage forms of the present invention.

Title: Apparatus for and method of evenly distributing an electrical load across an n-phase power distribution network
Inventor: WITTNER LUPU
IPC: H02J3/14
Filed: 1997-12-05
Abstract: An apparatus for and method of evenly distributing an electrical load across an n-phase power distribution network. The current in each incoming phase (.SLZERO.1, .SLZERO.2, and .SLZERO.3) and in each branch circuit (1-5) is measured by a current sensor (16, 18, 20, 42, 44, 46, 48 and 50). The outputs of the current sensors are monitored by a processor (12).  Associated with each branch circuit is a multi-pole switch (22, 24, 26, 28 and 30) and a conventional circuit breaker (32, 34, 36, 38, 40).  Each switch (22, 24, 26, 28 and 30) is able of connecting its corresponding branch circuit (1-5) to any incoming phase (.SLZERO.l, .SLZERO.2, and .SLZERO.3), and of disconnecting the branch circuit (1-5) from all n phases (.SLZERO.l, .SLZERO.2, and .SLZERO.3). The processor (12) periodically monitors currents flowing through each incoming phase and, based on branch circuit load conditions (1-5), reprograms the switches (22, 24 and 26) to keep the branch circuit loads (1-5) evenly distributed across all three incoming phases (.SLZERO.1, .SLZERO.2, and .SLZERO.3).

Patent CA-2275440-A1 (CA)
Inventor: BRINGAS PEREZ RICARDO
IPC: C07K7/23
Filed: 1997-12-17
Abstract: The invention relates to the field of genetic engineering and biotechnology and particularly to the use of a peptide derived from GnRH for the immunocastration of mammals. Vaccinations tests have been carried out in mammals with the gonadotropine release hormone (GnRH), in order to ellicit and immune response which neutralizes the activity of said hormone. The present invention relates to the use of a GnRH variant of mammals wherein a glycin residue has been substituted by a prolin residue in position 6: Glu-His-Trp-Ser-Tyr-Pro-Leu-Arg-Pro-Gly. This substitution or change has induced an immune response which is superior than that of natural GnRH, when both are coupled to a same carrier protein, in experiments carried out in pigs. This same result can be expected in any other mammal since this hormone is present in all species.

Abstract: The invention relates to electroplating with refractory metal, mainly tantalum and niobium, from molten salts and can be applied in chemical, metallurgical, pharmaceutical, medicinal industries, turbine manufacture, air- and spacecraft, and other areas of engineering, in creation of corrosion-resistant and barrier coatings. The essence of the invention is that when the article to be coated is immersed into a molten electrolyte containing fluorides of both refractory and alkali metal and a eutectic melt of sodium, potassium and cesium chlorides, the article is warmed up to the working temperature of the electrolyte of 700-770 ~C whereupon direct or reverse electric current is passed through the electrolyte, the current parameters being adjusted so that quantity of electricity in the anodic Qa, and cathodic Qc, parts of the electroplating cycle corresponds to the ratio OQa/Qc < 0.9. To improve the article quality it is desirable that the weight of the electrolyte exceeds that of the article by 5 times or more. The technical result attained is the production of uniform-thickness, high quality tantalum or niobium coatings on articles for industrial applications made of conventional materials. Open porosity of the resulting coatings is not higher than 0.001 %, adhesion to the substrate is as high as 8 kg/mm2.
