Abstract: ABSTRACT         Flanged steel wheels remain in service on rail cars, locomotives, and other heavy rail guided machinery until they no longer maintain minimum specified rim or flange profile dimensions.   If at this point the wheel rim or flange profile cannot be returned to at least minimum specifications by surface machining operations, the wheel is condemned as being defective and is removed from service and scrapped.   It is desirable to be able use an automated inspection method to determine if a wheel is approaching this condemning limit for profile wear;  to date no satisfactory means for doing so is commercially available.  In this  method,  high  flange,  thin  rim,  and thin  flange  type  surface profile defects  are detected automatically while  equipment  or  axle mounted  wheels  pass  between  rail  mounted  antennae  which  transmit microwave radiation.   This antennae configuration, when energized and influenced by a wheel possessing condemnable rim thickness,  flange thickness, or flange height surface profiles will cause a D.C. voltage to propagate at a microwave detector inserted into an interconnected comparison  bridge  network.    By  monitoring  this  detector  with  a suitable  controller  it  is possible  to  effect  alarms  at  a  remote location which will not only notify operating personnel but will also sequentially log the date and time of the alarm occurrence, axle and wheel position location of the defective wheel, and note the specific profile defect present on the wheel.

Abstract: "METHOD AND APPARATUS FOR MEASURING FLUID VISCOSITY"    ABSTRACT OF THE DISCLOSURE        A transient flow capillary viscometer is provided for establishing a measure of the viscosity of a highly viscous test fluid.  More particularly, a capillary tube filled with the test fluid is provided.  The viscometer relies upon inducing a step change in the differential pressure across the ends of the capillary tube, which causes the fluid to flow therein.  The resultant decrease in pressure drop as a function of time, i.e. the half-life of pressure decay, is monitored and provides an approximate measure indicative of the viscosity of the fluid.

Abstract: ABSTRACT               Disclosed is a stopper for wine bottles and the like which comprises an insert for a well in a wine cork and a puller device for operative association with the insert and cork when the stopper is in the neck of a bottle.  The puller device as part of the stopper enables the cork to be pulled without auxilliary devices such as a corkscrew.  The stopper insert is capable of being pre-assembled with the cork without any stress being imparted to the cork.  This enables existing corking equipment to be used with the stopper.  The puller device can be inserted after corking before lead foil is applied about the neck and cork stopper.    With appropriate modification to corking equipment, the stopper of my invention could be totally preassembled before corking of the bottles.

Abstract: PATIENT INTERFACING SYSTEM AND METHOD TO PREVENT WATER CONTAMINATION                            Abstract Described herein is a patient interfacing system for sampling the inspired and expired gases of a patient and removing moisture from the sample.   In one embodiment of the present invention,  a patient link receives the gases from  the  patient's  airway  circuit  and  a vaporization section vaporizes  condensed moisture  in the sample.   A separator section allows the vaporized moisture component of the sample to exit the patient interfacing system before the gas sample reaches the monitoring instrument.  A filter may  also  be  utilized  to  prevent  condensed  moisture, particulates  and  liquids  from  entering  the  monitoring instrument.   Thus, the patient interfacing system of the present invention provides a reliable, cost effective and efficient means for delivering gas samples to a monitoring instrument which  reduces  or prevents water  condensation inside  the  gas  analysis  portion  of the  monitoring instrument.

Responsive to a firmware load instruction (23), the data controller reads the first through the N-th firmware data from the holding device as first through N-th read-out data.  The holding device makes the memory device memorize the first through the N-th read-out data as first through N-th memorized data.  Connected to the control memories, the data controller makes the control memories of the first through the N-th control memory layers memorize the first through the N-th memorized data through the data path.  In this event, the data controller makes at least one control memory of each of the first through the N-th control memory layers simultaneously memorize each of the first through the N-th memorize data.  The holding device may be included in one of the input-output devices.  The firmware data may be stored in the control memories successively from the first control memory layer to the N-th control memory layer.
