Patent CA-1086590-A (CA)
Inventor: NUGENT DUANE C
IPC: F24S10/40
Filed: 1977-10-20
Granted: 1980-09-30
Abstract: ABSTRACT OF THE DISCLOSURE    The disclosure relates to a modular form of solar energy collector apparatus in which several double-wall glass tube collectors, each with avcuum jacket, depend from opposite sides of an elongated manifold.  The manifold includes split halves of foamed polymer insulation and rigid fiberglass reinforced skin thereon, assembled about closed-looped, serpentine liquid carrying tubes preferably of metal or glass in U-tube configu-rations depending from the manifold halves and extending into the larger double-walled glass tubes, the serpentine tube being connected, respectively, into inlet and outlet header pipes The interior chamber of the collector tubes is closed by the manifold, thereby enclosing a part of each U-tube branch of the serpentine in a non-turbulent air space.  Solar energy collected on the absorber surface of the inner glass tube wall is trans-mitted to the U-tube and liquid therein.  The U-tube within the collectors is blackened and non-reflecting.  Principal heat transfer from absorber to U-tube is by radiation with some conduction and convection transfer.  The heat transfer liquid is entirely within a closed circuit, which avoids leaks, re-duces weight, and cycle time of the liquid is reduced to a fraction of other liquid systems.    The manifold and tubes are fastened to a support structure of novel construction enabling fabrication as a module and mounting on a solar exposure of a structure such as a roof, wall or frame.  Several modules are interconnectable to desired capa-city for a particular solar powered heating or cooling system.

Abstract: BOILER COLD START USING PULVERIZED COAL IN IGNITOR BURNERS            Abstract of the Disclosure:    An ignition, warm-up and low-load-stabilization system for furnaces fired by pulverized coal.  In conjunction with a system in which pulverized coal is sent directly from a coal mill to a load-bearing nozzle and in which combustion air is brought to the nozzles from an air preheater that uses hot furnace gases to warm the combustion air, ignitor nozzles are provided that are supplied by pipes bearing coal from which the drying air has been separated.  Combustion air for the ignitor nozzles is heated by an independent heat source that heats the combustion air or a portion thereof to a temperature higher than that of the air supplied by the air preheater.  Such a coal-fired ignitor burner can replace oil or gas-fired ignitors and warm-up guns and thereby reduce the amount of oil or gas used in ignition, warm-up, and low-load stabilization.

Abstract: PHN. 8973.           ABSTRACT:         High-pressure sodium vapour discharge lamps are used which contain an electron-emitting material consist-ing of alkaline earth metals bound to oxygen and tungsten bound to oxygen.  It has been found that such lamps which have a high Hg/Na ratio, use neon/argon as a starter gas and have powers of less than 400 W fail prematurely when the alkaline earth metals and tungsten in the electron-emitting material are present in stoichiometric quantities (total alkaline earth metal oxide : NO3 = 3).  The free ends of electrodes of lamps according to the invention are wound with tungsten wire.  Electron-emitting material com-prising barium, strontium and calcium bound to oxygen and tungsten bound to oxygen is disposed in the cavities formed between the tungsten wire turns.  The molar ratio of the total barium, strontium and calcium bound to oxygen to the tungsten bound to oxygen is between 8 and 50.

Abstract: LASER TUNNELLING DEVICE            Abstract of the Disclosure A device for use primarily in medical applications to locate, analyze, illuminate and destroy obstructions in a tube.  The device includes a fiberoptics bundle for insertion to the tube in a flexible conduit.  The conduit includes a connection to a suction source at one of its ends, a valved means of controll-ing the application of suction, which functions also to control the injection of locating material, and a connection to the fiberoptics bundle.  The fiberoptics bundle is divided into an illuminating source bundle portion, a viewing bundle portion and a laser bundle portion.  The device functions to remove obstructions in tube structures, both bilogical and non-biological, by insertion of the conduit sheathed device into the tube structure, distal to the obstruction.  A dye, or the like, is injected and the site of the obstruction thereby determined under the guidance of image-intensified fluoroscopy.  The conduit is moved toward the obstruction until resistance is felt, and the negative pressure source or suction applied to attach the conduit to the obstruction.          The physical contact between the device and the obstruction, as well as the physical appearance of the obstruction, are determined by direct viewing.  The obstruction is then vaporized by the laser beam with vaporized debris being constantly removed by the suction, and at the same time, the conduit is advanced by the suction, so that it is in continuous contact with the obstruction.          A transparent reservoir is connected to the conduit so that upon complete tunnelling an indication thereof may be observed in the transparent reservoir.
