    摘要： A tall tower equipped with a plurality of flashing beacon lights and continuous obstruction lights is sensed at a remote location for indicating whether all lights are in proper working order, and if they are not, the system identifies the fault to the remotely located operator.

    摘要： An ultrafiltrate prepared from the blood of a host is put into the venous bloodstream of a recipient while simultaneously withdrawing an ultrafiltrate from the arterial bloodstream of the recipient at approximately the same rate. The ultrafiltrate intended for the recipient is prepared by withdrawing it from the arterial system of the host while simultaneously introducing the recipient''s ultrafiltrate into the host''s venous system for processing. The parabiotic exchanges for both host and recipient may be done simultaneously; but if they are not, it is preferred to collect the ultrafiltrate of each in a plurality of quantities. In the latter case, the exchange is effected by introducing the ultrafiltrate in inverse order of purity in the case of the recipient and by introducing the ultrafiltrate into the host in order of purity of the quantities to promote more efficient processing by the host. Preferred apparatus for a plasma extractor and continuous ultrafilter are also disclosed.

    摘要： This invention relates to a blood flowmeter comprising a catheter suitable for insertion into a blood vessel, thermal resistors (thermistors) connected in electrical circuits disposed in the catheter near the insertable end of the catheter; and moving means for moving the thermistors out of the insertable end of the catheter into the blood flow and, when desired, back into the catheter. Means are also provided for measuring electrical response through the thermistors. Flow characteristics in the blood vessels are determined by observing changes in measured electrical response through the thermistor circuits.

    摘要： A PROBE HAVING ELONGATED, SEPARABLE SIDE PRESSURE PLATES IS INSERTED INTO THE SOIL UNDER TEST, SEPARATING THE SOIL AS IT PENETRATES. AFTER THE PROBE IS INSERTED, A LATERAL FORCE IS APPLIED TO THE PRESSURE PLATES TO COMPRESS AND CONSOLIDATE SOIL ENGAGED BY THEM WITH A KNOWN LATERAL CONTACT PRESSURE. THE EXTERIOR SURFACES OF THE PRESSURE PLATES ARE PROVIDED WITH METAL BARBS OR TEETH TO CAUSE SHEARING WITHIN THE SOIL AS THE PROBE IS REMOVED UNDER FORCE. AS THE PROBE IS REMOVED, MEASUREMENTS ARE RECORDED OF THE RESISTING FORCE REQUIRED FOR SHEARING AND THE DISPLACEMENT OF THE PROBE. THE SEGEMENTS OF THE PRESSURE PLATES EXTENDING ABOVE THE SURFACE OF THE SOIL RELAX SO THAT THE ENTIRE LATERAL FORCE CAUSING EXPANSION OF THE PLATES IS EXERTED ON THAT FORCE CAUSING EXPANSION OF THE SOIL. THE PROBE IS PULLED OUT IN INCREMENTS, THIS DECREASING THE AREA OF THE PRESSURE PLATES IN CONTACT WITH THE SOIL. HOWEVER, THE LATERAL PRESSURE EXERTED ON THE SOIL INCREASES CORRESPONDINGLY-THIS FORMING A OF THE COHESION AND INTERNAL FRICTION OF THE SOIL WITHOUT HAVING TO FORM A BORE HOLE.

    摘要： Calcium sulfate is subjected to gaseous reduction at a high temperature to obtain an SO2 containing gas product and a CaO solid product. The reduction is carried out in a fluidized reaction bed by flowing proportioned air and natural gas into and through the bed to fluidize the finely divided calcium sulfate and to heat to reaction temperatures. The natural gas is only partially burned within the bed, thereby also producing reducing quantities of CO and H2. In a preferred embodiment, the calcium sulfate feed is preheated by direct contact with the gas product to recover part of the heat therefrom, and the gas product of reduced heat content is then subjected to indirect countercurrent heat exchange with the air being supplied to the reaction bed.

    摘要： A LASER IS USED TO DETERMINE THE SIZE OF SMALL PARTICLES OR OTHER OBJECTS. THE PARTICLES ARE INTRODUCED INTO THE ELECTROMAGNETIC CAVITY OF THE LASER IN AN AQUEOUS MEDIUM FLOWING THROUGH A CHANNEL WHICH INTERSECTS WITH THE LASER BEAM. THE CHANNEL IS DEFINED IN A QUARTZ HOUSING, AND IT IS ORIENTED RELATIVE TO THE ADJACENT QUARTZ WINDOWS AT THE BREWSTER ANGLE TO INSURE COMPLETE TRANSMISSION OF THE LIGHT. A LIGHT POWER METER MONITORS THE LASER OUTPUT AND CONVERTS IT TO AN ELECTRICAL SIGNAL REPRESENTATIVE OF THE INTENSITY OF THE LASER BEAM. AS INCIDENT LIGHT STRIKES THE PARTICLES, THE TOTAL SCATTER WILL DEPEND UPON THE SIZE OF THE PARTICLES, AND A CHANGE WILL BE REFLECTED IN THE LASER OUTPUT DUE TO THE GAIN CHARACTERISTICS OF THE LASER. THE CHANGE IN LASER POWER BEARS A ONE-TO-ONE CORRELATION WITH PARTICLE SCATTERING CROSS SECTION.
