Title: Rotary coupling apparatus for transmission cables
Inventor: TUTTLEBEE ROGER
IPC: G02B6/24
Filed: 1999-02-08
Abstract: A rotary coupling apparatus includes a stationary housing defining a chamber, an elongated hollow shaft extending through the chamber of the housing and rotatable relative thereto, a drum supported about the shaft and rotatable therewith, and an elongated coupling cable for carrying communications elements being disposed in the chamber and interconnecting the stationary housing with the rotatable drum. The stationary housing has a pair of spaced end walls and a circumferential side wall disposed therebetween. The end walls define the chamber therebetween and the circumferential side wall defines an outer periphery of the chamber. The shaft extends through the chamber between the end walls and is mounted to undergo rotation relative to the end walls.  The circumferential side wall is radially spaced outwardly from and extends about the rotatable shaft and drum. The coupling cable terminates in a pair of opposite end portions, a first being secured to the stationary housing and a second being secured to the rotatable drum and shaft such that the second end portion of the coupling cable rotates with the drum and shaft as the first end portion of the coupling cable remains stationary with the stationary housing. The coupling cable is adapted to wind about the rotatable drum away from the circumferential side wall of the housing until reaching a wound condition about the drum and to unwind from the drum toward the circumferential side wall of the housing until reaching an unwound condition as the drum and shaft undergo rotation in clockwise and counterclockwise directions relative to the housing.

Title: Electrochromic metal oxides
Inventor: COLEMAN JAMES P
IPC: G02F1/1523
Filed: 1997-09-26
Abstract: Tin oxide doped with an electrochemically effective amount of a metal, e.g., antimony or niobium, which provides a color change when the doped tin oxide is exposed to an electrochemical potential in the presence of mobile ions.  Particles of electrochromic doped tin oxide, e.g., coated on a white or pastel pigment substrate, have a contrast ratio greater than 1.2, where contrast ratio is a measure of electrochromic functionality of a material and is the ratio of reflectance of the material in an oxidized state to the color of the material in a reduced state and where color is a photodiode measurement of the value of light reflected off the oxidized or reduced material from a constant source of light shining on the material. Such doped tin oxide-containing particles are useful as electrochromic material in display devices, and may be employed in display devices that advantageously exhibit a linear or nearly linear relationship between stored electrical charge and voltage, and which also exhibit linear or nearly linear optical characteristics as a function of voltage. Electrochromically active materials made from metal oxides and doped with substances other than antimony and niobium have also been found with high contrast ratios. These additional doped materials may be substituted for electrochromically active antimony-doped tin oxide in electrochromic displays.

Title: Thermochemical regenerative heat recovery process
Inventor: KOBAYASHI HISASHI
IPC: C01B3/34
Filed: 1999-04-28
Abstract: A furnace is provided having at least two regenerator beds for heat recovery. While a first bed is being heated by hot flue gases produced by combusting a fuel and an oxidant in the furnace, a second bed, heated during a previous cycle, is cooled through carrying out an endothermic chemical reaction therein, for example the reforming reaction of a hydrocarbon with water vapor and carbon dioxide and/or the dissociation of a hydrocarbon. Once the second bed is cooled by the endothermic reaction, the hot flue gases are redirected to it while the first bed, now hot, is used for carrying out the endothermic chemical reaction. Thereafter the cycle is repeated.

Abstract: An artificial esophagus characterized by comprising a tube having a layer of microfibrillar collagen on its outer side. It is capable of retaining over a certain period the effect characteristic of collagen such that esophageal epithelium regeneration is accelerated in a defective region of the esophagus to thereby effect esophageal neogenesis.

IPC: B01J20/32
Filed: 1999-07-09
Abstract: Pentadentate chelators (PDC) resins are the metal chelate resins capable of forming the octahedral complexes with several polyvalent metal ions including Cu2+, Ni2+, Zn2+ and Co2+ with five coordination sites occupied by the chelator. This results in the best stability of the complexes and in one coordination site free for interaction and selective binding of accessible cysteine/histidine residues and chiefly histidine containing biomolecules such as proteins or peptides etc.      Cu-PDC can be used as concentration resins to reduce the volume of a protein solution. It can be used also as a universal support for immobilising covalently all proteins, using a soluble carbodiimide.

Title: Fault detection and isolation in a synchronous optical network (sonet) and in a synchronous digital hierachy (sdh) network
Inventor: ZELINGHER SIMON S
IPC: H04J3/14
Filed: 1999-07-16
Abstract: An in-band fault detection and isolation system and method for networks such as Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) networks. Fault detection may be quickly and efficiently performed by a network without requiring modification to any add/drop multiplexers (ADMs) and/or without the involvement of an external network management system (NMS). To accomplish this without violating SONET/SDH standards, a new signal, called a fault isolation signal in the path (FIS-P), is proposed. The FIS-P may be used in lieu of an AIS-P to support special applications on certain digital cross connect (DCS)-to-DCS path segments. Moreover, the present invention may be implemented such that the behavior of path terminating equipment (PTE) is unaffected.

Title: Process for treating waste water
Inventor: CAMPBELL BRYAN A
IPC: C02F1/72
Filed: 1999-09-15
Abstract: A process for treating bacteria laden effluent from a sewage treatment digester to condition the effluent for release into the environment includes the steps of thoroughly mixing the effluent with a bactericide, conveying the mixed effluent to a reaction zone to completely kill any bacteria entrained in the waste water to provide a substantially bacteria free effluent, mixing an oxidant with the bacteria free effluent, maintaining the mixture for a sufficient time to permit substantially complete oxidation and neutralization of entrained bactericide, and discharging the treated effluent into the environment. In an alternative procedure the treated effluent is passed through a neutralizing filtration step to neutralize any active bactericide before the effluent is discharged to the environment.
Patent CA-2284188-A1 (CA)
Title: High efficiency alternating and direct current electrostatic motor
Inventor: GENDRON DANIEL
IPC: H02N1/00
Filed: 1999-09-15
Abstract: The present invention provides an electrostatic motor wherein the poles of the stator have a substantial geometry in the shape of fixed "comb-poles" adapted to be crossed by moving "comb-poles" of the rotor. The fixed comb-poles are equally spaced apart, radially and inwardly extending from an electrically insulating hollowed outer cylinder forming the stator, while the moving comb-poles are equally spaced apart, radially and outwardly extending from an electrically insulating inner cylinder forming the rotor and located inside the stator.    Having all those combs essentially facing each other allows for taking full advantage (100% in theory) of the electric force vector created between adjacent comb-poles of the stator onto the free moving rotor comb-poles when they are electrically charged. The rotor comb-poles become charged by passing through a stator comb-pole thereby eliminating any known collector devices. This geometry allows for making AC or DC motors using the electrostatic power with a theoretical efficiency of nearly 100%.
