Title: Strippable tight buffered optical waveguide fiber
Inventor: CHIEN CHING-KEE
IPC: C03C25/10
Filed: 1991-12-12
Abstract: ABSTRACT OF THE DISCLOSURE      A tight buffered optical waveguide fiber having improved  strippability  is  provided.   The  fiber includes  a  core,  a  cladding,  a  first  protective coating in contact with the cladding, an interfacial layer in contact with the first protective coating, and a buffer layer in contact with the interfacial layer.   The  interfacial  layer  comprises  a  solid lubricant   such   as   sub-micron   particles   of polytetrafluoroethylene  (PTFE)  in  a  film-forming binder.   The  concentration  of  particles  at  the external  surface  of  the  interfacial  layer  is preferably  greater  than  the  concentration  at  the internal surface  so  that  the interfacial  layer is more adherent to the first protective coating than to the  buffer   layer.    This   differential   adhesion facilitates  the  manufacturing  process  while  still allowing  long  lengths  (e.g.,  a  foot  or  more)  of either the buffer layer or both the buffer layer and the first protective coating to be removed from the cladding without damage to the fiber's physical and optical properties.  A countercurrent technique for applying the  interfacial  layer to  the fiber  as  a water dispersion is also disclosed.

Title: Repulsion device for low capacitance electrostatic painting systems
Inventor: HARTLE RONALD J
IPC: B05D1/04
Filed: 1992-02-05
Abstract: REPULSION DEVICE FOR LOW CAPACITANCE ELECTROSTATIC PAINTING SYSTEMS          Abstract of the Disclosure An electrostatic repulsion device is pro-vided in an electrostatic spray paint booth having a grounded ceiling and conveyor to improve transfer efficiency in applying the paint to a workpiece and maintain a safe working environment without requiring protective fencing between an operator and the appli-cation equipment.  The device includes a length of electrical cable having a central resistive conductor and an insulation layer.  The cable is designed to produce low electrical capacitance in operation when connected to a high voltage source.  Conductive pins are mounted along the cable through the insulation to contact the conductor.  The conductive pins are arranged parallel to the spray path in two longitudi-nal groups, with the first set being diametrically opposed to the second set.  Each conductive pin has a discharge end that is substantially flush with the outside surface of the insulation of the electrical cable.  The device is transversely mounted with respect to a spray path of charged, atomized paint particles dispensed from a non-conductive, rotary atomizer or low capacitance spray gun, so that an electrostatic field from the first set of conductive members repels the atomized, charged paint particles away from the grounded ceiling and conveyor of the paint booth towards a workpiece.  The electrostatic field produced by the second set of conductive members bleeds accumulated charge from the low electrical capacitance repulsion device before a high energy spark or discharge can occur whenever a grounded operator or object comes into proximity with the device. This safety feature eliminates the need for protective fencing and interlocks within the spray booth.

Patent CA-2081168-A1 (CA)
Inventor: BALES BRUCE M
IPC: H04Q3/00
Filed: 1992-10-22
Abstract: Routing calls using a new protocol message which is a redirect message in a telecommunication system having a number of switching nodes to avoid circular paths among the switching nodes and for rerouting calls in the event of failures or overload conditions. During the establishment of a call from an originating switching node to a destination switching node where the call path has already been setup from the originating switching node through an intermediate switching node, a switching node is responsive to a setup message from the intermediate switching node requesting extension of the call path through the switching node to determine if such an extension would create a circular path. If circular path would be created, the switching node redirects the call (by using the redirect message) back to the intermediate switching node and indicates in that message to which switching node the call path should be extended. In response to the redirect message, the intermediate switching node reroutes the call path. Further, the redirect message entirely removes the call path between the switching node and intermediate switching node.

Filed: 1992-11-03
Abstract: METHOD OF SCREENING FOR PACEMAKER PATIENTS MYOCARDIAL ISCHEMIA                 ABSTRACT OF THE DISCLOSURE     A method for screening patients to assess for myocardial ischemia when those patients have an implanted pulse generator/lead system for cardiac rhythm management,  including the steps of implanting  the  pulse  generator/lead  system  and  waiting  a predetermined  period  of  time  until  the  sensing/stimulating electrodes become stabilized through tissue ingrowth.  A baseline electrocardiogram  is  then measured using the  implanted pulse generator.  This initial electrocardiogram serves as a baseline for future  reference  and may be  stored within  the  generator  or telemetered to an external programmer unit for storage.  At each subsequent followup by the physician, a new electrocardiogram is sampled and the characteristics of the ST segment thereof are compared with the ST segment characteristics of the baseline electrocardiogram.  If this comparison reveals a change in the ST segment  from the baseline  in at  least  one  of  its  duration, amplitude or polarity characteristics, myocardial ischemia may be inferred.

Patent CA-2095646-A1 (CA)
Inventor: PETERSCHECK HERMANN W
IPC: C02F11/08
Filed: 1993-05-06
Abstract: A process is disclosed for co-processing spent nitric acid wash water with organic or biological wastes under wet oxidation conditions  whereby  the  nitrogen  content  of  the  waste  and  the chemical oxygen demand and the nitrogen content of the nitric acid wash water and of the organic or biological wastes are significantly reduced.  The nitric acid wash water is the waste stream generated by  descaling wet  oxidation  reactors  used  for  the  treatment  of organic  or  biological  wastes,  especially  municipal  wastes.  The process of this invention can be carried out in conventional above ground equipment or in a subterranean, down-hole reactor having a vertical  configuration  which  utilizes  gravitational  forces  to provide a high pressure reaction environment.  The nitric acid wash water  and  organic  wastes  are  reacted  with  an  oxidant  at  a temperature greater than 150~C and a pressure suffient to keep water in the liquid state.  The nitric acid wash water is mixed with the organic  waste  or  is  introduced  through  the  oxidant  (preferably gaseous oxygen) inlet in such a manner that gas with water vapor and the remaining acid provides a liquid film so there are essentially no "dry spots" in the oxidant inlet lines.
