Title: Apparatus to mix and burn fuel with waste gases
Inventor: REED ROBERT D
IPC: F23G7/06
Filed: 1976-10-15
Granted: 1979-05-08
Abstract: Abstract of the Disclosure Apparatus for the useful recovery of heat from waste gases of substantial heat value which would otherwise be burned without the recovery of the heat, comprising a special burner head attached to a burner pipe, with a smaller diameter pipe passing axially through the burner pipe.  Fuel gas or steam is applied through the axial pipe to a first plurality of nozzles arranged on the surface of a cone, spaced circumferentially around the axis of the head, and directed outwardly at a selected angle with the axis.  The first set of nozzles lead into a corresponding second set of larger diameter second nozzles.  There are longitudinal, circumferentially-spaced bores, which intersect the second nozzles, through which the waste gases are aspir-ated, and are sprayed out in the form of a conical sheet, with the fuel gas or steam,into a burning space, such as a furnace, wherein the heat liberated by the combustion can be recovered.  The velocity of flow of fuel gas or steam through the first nozzles must be at least .25 mach in order to provide suffi-cient lowering of the pressure in the second nozzles to aspirate the waste gases.

Abstract: ABSTRACT OF THE DISCLOSURE A drill string holder for a rock drilling machine has two jaws opposite each other for gripping a drill string e.g. the drill string in core drilling with a diamond drill bit.  The jaws are forced into their gripping positions by means of a heavy spring.  A first selectively actuatable hydraulic piston is arranged to overcome the spring and permit the jaws to release their grip.  A selectively actuatable second piston is located in-side the first piston.  By means of the second piston, the operator can apply a selectively variable force to the jaws when the jaws are released from the spring.  This permits the operator to let the drill string gently down into the bore hole by applying a controlled braking force on it.

Abstract: ABSTRACT OF THE DISCLOSURE       Conventionally, grab bars used in baths, showers and the like are either secured to a flange which in turn is held to a supporting surface by heavy duty screws or is welded to a flange and held by set screws to an attaching plate attached to the supporting surface.  The first method is easily detached so that it can readily be stolen and the second method is rela-tively expensive inasmuch as the weld has to be ground plated and then polished.  In hospitals, such devices have to be  fre-quently and readily attached for cleaning.  The present device comprises an apertured support plate securable to a wall sur-face or the like and an end cap is provided with a central socket within which the end of the hollow grab bar engages.  A nut is spot welded or otherwise held within the end of the grab bar and a bolt holds the bar firmly within the socket.          Recessed set screws adjacent the perimeter of the end cap de-tachably secure the end cap and bar to the supporting plate and an inclined surface is provided at the rear outer peri-meter of the supporting plate engaged by the set screws thus drawing the end cap into sealing and clamping engagement not only with the end cap but also with the supporting surface, thus eliminating ready detachability by unauthorized personnel yet at the same time providing a smooth finished surface which is easily maintained in a clean and sterile condition.

Abstract: A METHOD OF DETECTING HEATER RESISTANCE            INDEPENDENT OF CONTACT RESISTANCE                       Abstract A constant current is applied through a heater by means of an electrical connector which mates with ter-minal pins of the tube.  The applied current causes a voltage across the heater.  A first voltage measurement is made across the heater at a first time. After a pre-determined time interval has elapsed, a second voltage measurement is made across the heater.  The value of the first voltage measurement is subtracted from the value of the second voltage measurement and the value of the differ-ence obtained is compared with a predetermined reference value.  If the difference value is less than the reference value, a first nominal value of heater resistance is indicated.  If the difference value is greater than the reference value, a second nominal value is indicated.  The nominal heater resistance values are detected independent of the electrical connector contact resistance.
