Abstract: THROUGH THE DOOR WATER AND ICE DISPENSER               ABSTRACT OF THE DISCLOSURE         A through-the-door ice and cold water dispenser for domestic refrigeration units provides a housing positioned within a recess formed in the door insulation.  The dispenser provides an actuation cradle formed with a smoothly curved concave surface in combination with a switch operating system which requires low forces for operation so that the dispenser can be actuated by fragile containers, such as styrofoam cups. An insulated damper door is closed when the dispenser is not operating  to  prevent  heat  transfer  into  the  freezer compartment where the ice is produced and stored.  A heater positioned against the damper door operates to release the damper door should it become frozen in the closed position. All of the controls for the dispenser are located in the upper portion of the housing and are accessible with a minimum amount of disassembly when service or maintenance is required. A spill tray is located in the bottom of the dispenser recess to contain and retain spilled water and melted ice water.  The spill tray is easily removable for dumping.

Title: Laser rangefinder testing system incorporating range simulation
Inventor: RUHL JOSEPH W JR
IPC: G01S7/497
Filed: 1993-12-09
Abstract: LASER RANGEFINDER TESTING SYSTEM  INCORPORATING RANGE SIMULATION                          ABSTRACT A range extinction simulator system that simulates an outdoor laser test range in a relatively small area, which provides for a computer controlled, electronic laser range simulator used to test laser rangefinders. The system evaluates a laser rangefinder's output energy and programs a laser transmitter to fire into the rangefinder at a specific optical power level needed to simulate a return signal from a target for a given range, atmospheric attenuation, and target reflectivity. This invention allows laser rangefind-ers to be tested without the necessity of a long distance (typically outdoor) laser range. The system provides for a significant cost savings over current test systems andimproves the ability to perform varied tests on laser rangefinders. The specific advan-tages that are realized are the elimination of the outdoor, fixed range, laser test facility with its associated maintenance and safety problems; the elimination of the necessity to move hardware to be tested from the manufacturing floor or development laboratory to the outdoor laser range for testing; the ability to test laser rangefinders during bad weather, and the ability to test laser rangefinders at variable ranges, target reflectivities, and atmospheric conditions, rather than at a single fixed range, single target reflectivity, and uncontrolled atmospheric conditions.

Title: A method for detecting nitric oxide, nitrosonium equivalents, s-nitrosothiols and s-nitroso-proteins in biological systems
Inventor: STAMLER JONATHAN
IPC: G01N21/63
Filed: 1993-04-21
Abstract: Nitric oxide, nitrosoni-nm, S-nitrosothiols, and S-nitroso-proteins can be de-tested in biological samples, using a method which in-volves injection of samples into a photolysis cell, prior to detection of chemilumines-cence generated by the reac-tion between nitric oxide and see Formula I ozone. To detect S-nitrosoth-iols and S-nitroso-proteins separate aliquots of the same samples are subjected to pre-treatment with mercurous ion, and a protein-precipitat-ing agent, respectively, and the resulting nitric oxide sig-nals are compared to those generated by untreated sam-ples. This method is useful for monitoring the levels of nitric oxide bioactivity in both normal physiological states, and diesease states, such as septic shock, atherosclerosis, thrombosis, hyperhomocysteinemia, pulmonary hypertension, malignancy, infections and central nervous systems disorders.

Title: Method and apparatus for zero-calibration of a raman spectroscopy system
Inventor: MITCHELL JOHN
IPC: G01J3/02
Filed: 1994-03-28
Abstract: METHOD AND APPARATUS FOR ZERO-CALIBRATION      OF A RAMAN SPECTROSCOPY SYSTEM    Abstract of the Invention A Raman spectroscopy system and method for determining a zero-calibration level.  A gas sample chamber is located within a resonant cavity.  A light source is located to cause light to be incident on the gas sample,  the light resonates in the resonant cavity.   Typically,  the light source and resonator cavity in conjunction form a laser source which propagates coherent,  monochromatic laser light energy through the gas sample.  This causes Raman scattering from the gases constituent in the gas sample.   The amount of Raman scattered light is measured at  detectors  along with light  due  to dark noise inherent in the detectors and glow from the laser source, i.e., light at wavelengths other than the laser light wavelength produced  by  the  laser  source.    The  resonator  cavity  is obstructed, via a ball inserted into the path of the laser beam for example, to prevent resonance.   If the light source and resonant cavity in conjunction form a laser,  prevention of resonance causes cessation of lasing.  Thus, substantially no Raman  scattering  occurs  and  detectors  measure  light  due primarily to background noise.  The origin of the measurement scale  for  the  detectors may then be  set  at  the measured intensity, i.e., a zero-calibration level for the detectors may be determined.
