Title: Photodetector amplitude linearity
Inventor: GANZ ALAN M
IPC: G01M11/00
Filed: 1993-01-21
Granted: 2002-11-26
Abstract: To calibrate a photodetector, a rotating disk with a slot is disposed in a light beam with decreasing speed from a defined maximum rotational speed to a defined minimum speed, while magnitudes and times of signals are read out and stored. Vernier pairs of signals occur in adjacent readout intervals, and non-vernier signals exclude the verniers. Readout times for verniers are used to estimate a preliminary function of rotations versus time. From the function are estimated an occurrence time for each pair and period of disk rotation at the time. Vernier fraction is the ratio of one signal in the pair to the sum of the pair. A time offset is the product of vernier fraction, slot fraction of the disk and the estimated period. Occurrence times corrected with the time offset are utilized to fit a corrected function of disk rotations versus time. Points of time for the non-vernier signals are determined from the corrected function, each point corresponding to disk rotations to a corresponding non-vernier signal. These points of time are employed with corresponding signals for linearly calibrating the photodetector.

Title: Boiler buckstay system for membraned tube wall end connection
Inventor: KREIDER EDWARD W
IPC: F22B37/24
Filed: 1993-04-02
Granted: 1994-07-12
Abstract: A buckstay system for a membraned-tube wall having a first wall section which meets a second wall section at an angle to form a corner, utilizes the natural load carrying ability of membraned tube wall construction to simplify or eliminate structural components previously utilized at such locations. Some embodiments use the membraned-tube wall corner configuration alone, or in combination with corner reinforcing plates and/or stiffening members to distribute combustion gas pressure loads to adjacent membrane-wall panels. Other aspects provide reinforcement only to accommodate transient overpressure conditions.

Title: Premixed/high-velocity fuel jet low no x burner
Inventor: JOHNSON GREGORY LYNN
IPC: F23C9/00
Filed: 1993-04-07
Granted: 2004-11-02
Abstract: The invention is a process for combusting a gaseous fuel in a burner to result in low NO x emissions by first feeding a gaseous fuel stream and an air stream to a premixer where the fuel and air streams are mixed to form a fuel-air mixture. The fuel and air streams are fed to the premixer at a fuel to air equivalence ratio of less than 1 (i.e., fuel-lean). Second, the fuel-air mixture is passed to a combustion chamber where the fuel is substantially combusted to produce a combustion chamber jet and flue gases. The combustion chamber jet and flue gases pass into a heating zone which may include a furnace, heater, or boiler. Third, at least two high-velocity fuel streams, optionally diluted with a non-reactive thermal ballast, are passed to the heating zone contemporaneously with the second step. The high-velocity fuel streams entrain at least a portion of the flue gases. The fuel in the high-velocity fuel streams is partially combusted prior to coming into contact with the combustion chamber jet. Last, the flue gases are removed from the heating zone.

Granted: 1999-05-11
Abstract: A plurality of 2-dimensional images of different visual directions when an object to be displayed is seen from different directions are inputted and a phase distribution at a hologram forming surface is calculated.  The calculated phase distribution is expressed on the hologram forming surface  of a phase expressing section  using a display.  A reproduction light is irradiated and converted into an optical wave front, thereby displaying a solid image.  The 2-dimensional images are inputted by photographing an object by cameras.  The 2-dimensional images can be also formed by interpolating calculations from the two 2-dimensional images which were actually photographed.  The 2-dimensional images which are used in the phase calculation  are subjected to the enlargement, reduction, and movement of the coordinate position, thereby adjusting the size and position of the solid image.  The phase distribution  is calculated from a plurality of 2-dimensional image  every red, green, and blue components, and the reproduction light of each color is irradited, thereby displaying a color solid image.

Abstract: An endoscopic tool for dispensing units of hemostatic agent broadly comprises a hollow tube which holds a plurality of individual units of the hemostatic agent, a valve at the distal end of the hollow tube which permits the hemostatic agent to pass therethrough but prevents foreign matter from contacting the hemostatic agent while in the tube, a plunger which extends into the hollow tube and contacts a proximal unit of the hemostatic agent, and a mechanism for moving the plunger distally in incremental movements to cause, upon each incremental movement, an individual unit of the hemostatic agent to be pushed through the valve. Typically, the mechanism for moving the plunger and the proximal end of the hollow tube are held in a handle, One mechanism for moving the plunger utilizes a portion of the plunger as a ratchet by forming a plurality of conical elements thereon, and utilizes a switch in the handle which has a V-spring coupled thereto as pawl for advancing the conical elements. A second mechanism utilizes a regularly shaped notched cutout in the handle as the ratchet, and a vertical protrusion on the plunger which extends through the cutout as an engagement element. The notched cutout provides resilient stops, and the protrusion is shaped to allow it to be forced in a forward direction through each resilient stop and then to sit in another notch.

Abstract: An  operable  single  use  needless  hypodermic  injector includes an elongate housing with a proximal end, a distal end, a longitudinal axis and a hollow bore therethrough.   The housing has a reservoir at the distal end with a generally cylindrical chamber for containing an injectable liquid.  The chamber has a longitudinal axis axially aligned with the housing longitudinal axis.  The chamber has a first open end adjacent the housing with a resilient stopper mounted slidably therein.  The reservoir has a  distal  second  end  with  an  orifice  which  is  in  fluid communication with the  chamber.   The resilient stopper serves to  seal the chamber and to eject the liquid from the chamber, forming  a  stream  at  the  orifice  when  the  stopper  is  moved distally in the chamber.   The injector has  an elongate piston mounted for axial movement within the housing bore and elements to axially bias the piston distally within the bore.  The piston has an armed position wherein it is positioned proximally within the bore in opposition to the biasing elements.  The injector has elements to retain the piston in the armed position and elements to  release  the  piston  from  the  armed  position.     When  the injector release elements are released, the piston moves distally to engage and move the resilient stopper distally, ejecting the liquid in the chamber through the orifice in a stream which will make a hypodermic penetration when the orifice is placed adjacent dermal  tissue.  The   injector  further  has  elements  which substantially prevent the piston from being retained in the armed position  once  the  release  elements  are  released,  thereby rendering the injector substantially non-reuseable.
