Patent CA-1185578-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE:           A heating system incorporating an absorption-type heat pump where the generator is heated by an aerated gas burner combusting a fuel-lean mixture whose efficiency is very high both at full and at part load and whose flue gas has a very low nitrogen monoxide and nitrogen dioxide content.  The mixture of fuel gas and combustion air flows from at least one mixer tube into a mixer and is fired on the burner plate, which is cooled by a rich solution and arranged at a distance of less than 50 mm. from the genera-tor. When the generator is of the vertical type, a burner is preferably installed where the burner plate surrounds the generator concentrically at such a distance from the bottom of the generator that only the central section of the generator is directly heated.  Preferably two heat exchangers are located in the flue duct downstream of the generator to recover the waste heat, indlucing the heat of condensation.  A second burner upstream of the first heat exchanger will light up and replace the first-mentioned burner for heating the generator, if the temperature falls below a preset lower temperature limit so that the heating system will meet demand even at very low outdoor temperatures.

Abstract: Case 5561 GLR/gs/ejl ABSTRACT OF THE INVENTION      Viscous materials,  such as bitumen,  can be recovered from subsurface  earth  formations,  such as tar sands,  by forming  a  shaft  or  first  borehole  to  the  base  of  the desired  subsurface  formation,  drilling  second  boreholes into  the  formation,  injecting steam into these boreholes until  the  temperature of parts of  the formation is such that the viscosity of the material is reduced, and collect-ing  the  liberated  material.   Variations  of  this  basic procedure are discussed.

Abstract: A B S T R A C T            A bioelectrode for use in the iontophoretic delivery of ions into the skin or tissue of a person includes either a recep-tacle or a composition of material suitable for holding ions to be delivered, a metallic foil disposed on one side of the receptacle or composition of matter, and a coupling device for electrically coupling the foil to an electrical source.          The other side of the receptacle  or composition of material is for placement against a person's skin or tissue so that ions may be delivered thereinto.  The receptacle or composi-tion of material both include features or characteristics which inhibit the migration of ions laterally therein, i.e., in a direction generally parallel to the surface of the skin or tissue, but which allow migration in a direction generally perpendicular to the surface of the skin or tissue, and in particular from the metal foil toward the person's skin or tissue.  The advantage of this capability is to provide a substantially uniform movement of ions into the skin or tissue over surface area of contact of the bioelectrode with the skin.

Abstract: STEAM GENERATING SYSTEM            Abstract of the Disclosure Disclosed is a catalytic combustor and systems for the boilerless stoichiometric production of a working fluid such as steam from a fuel-mixture comprised of a carbonaceous fuel and a diluent such as water mixed in a thermally self-extinguishing mass ratio.  Production of the steam is by a controlled substantially stoichiometric process utilizing a combustor to provide steam over a wide range of heat release rates, temperatures and pressures for steam flooding an oil bearing formation.  Even though formation characteristics change during a steam flooding operation, output steam of the combustor may be kept at a constant heat release rate by dividing the total amount of water passing through combustor between a first portion which is included in the fuel-mixture and a second portion which is injected into the heated products of combustion.          In this way, the space velocity of the fluid stream passing through the combustor catalyst may be kept within operational limits of the catalyst while maintaining stoichiometric combustion.  When necessary, preheating of at least one of the components of the mixture burned in the catalyst is provided by a portion of the heat of combustion.

Abstract: Adaptive Welding System Abstract of the Disclosure The performance of prior automated welding systems has been limited by their inability to independently track and weld and by their inability to accurately determine the groove profile.  The adaptive welding system disclosed herein includes a weld torch adapted to be controllably positioned in at least two dimensions, and means for tracking a workpiece seam  to be welded.  The tracking means is pivotably connected to the weld torch.  Means for pivoting the tracking means relative to the weld torch is included to permit both the tracking means and the weld torch to be independently maintained over the seam.  The tracking means monitors the seam by optical triangulation of a rotating laser beam projected against the workpieces.          This rotating laser beam crosses the seam twice during each cycle of the beam.

Abstract: ABSTRACT OF THE DISCLOSURE           A tuning control system for a klystron comprises a D.C. motor connected to the tuning shaft of the klystron.  A transducer derives a voltage dependent on the position of the tuning shaft and this is used together with a reference voltage to drive a control circuit for the D.C. motor.  A coincidence signal is produced every time the difference between the position voltage and the reference voltage becomes zero and the number of coincidences is counted.  After a predetermined number is counted the drive direction of the D.C. motor is switched so that the D.C. motor is turned a little in the opposite direction for a very short period of time. After that normal operation to reduce the error voltage to zero resumes. As the adjustment of the tuning shaft is only in one direction any backlash that may occur has no adverse effect.
