Abstract: LOW LOSS CLADDED OPTICAL FIBERS FROM HALIDES AND PROCESS FOR MAKING SAME                   Abstract Of The Disclosure A low loss cladded halide fiber for transmission of infrared energy is provided, and a process for making same, A single crystal ingot is grown from a powder of the core halide. The ingot is machined or extruded to provide a cylindrical billet core.  A sleeve member of a second halide of lower refractive index is prepared in the same fashion and is coaxially core drilled to accept the billet core.  The assembled composite billet is covered with a polymer film.  The film-covered billet is heated and extruded to form a polymer coated fiber in the range of 75 to 2,000 microns in diameter.  The extruded fiber may be rapidly cooled as it leaves the extrusion die to minimize grain size in scattering loss. The resulting fiber, suitable for surgical and industrial use, is protected from deterioration by the atmosphere.      In another embodiment of the fiber, a second polymer film is coaxially interposed between the billet core and cladding.      For applications of the infrared cladded optical fiber, a cable is provided formed from a length of the fiber contained in a coaxial outer strength member.

Abstract: A B S T R A C T    The apparatus for preheating heavy fuel oil has the task of using heavy fuel oil instead of light fuel oil at boilers (furnaces) and/or diesel motors. It is adaptable to preheating heavy fuel oil at light fuel oil systems especially For boilers (furnaces) and/or diesel motors.  With a preheater thermo insulated operated by a thermostat and a pre erected regulating circulating valve fitted to the return pipe connected through the regulating circulating valve at preheater, the apparatus can solve the task. 1.   Thus it is possible to obtain a substantial preheating saving and to reduce the weight of preheating installations and respective thermo insulations of the actual installations whose return pipe of burners and/or injection pumps are connected at daily or mixing tanks.     S P E C I F I C A T I O N        This invention relates to an apparatus for preheating of heavy fuel oil and using as defined in Claim 1 . It is common apparatus and installations which can use heavy 2.  fuel oil. For all boilers (furnaces) and diesel motors the return pipe of burners and/or injection pumps are connected at daily tanks or at mixing tanks. This kind of connection becomes unfavorable because a lot of preheating of heavy fuel oil is lost through the walls  of the tanks. For this reason it is necessary to be provided an appropriate thermoinsulation and a corresponding pre-heating installation. I have found these disadvantages may be overcome by providing an apparatus to be able to 3.  attract the return of heavy fuel oil from burner/injection pump in way to be preheated and to be oriented again toward the burners/injection pumps. In this manner the invention solves the task to use with a small quantity of energy heavy fuel oil instead of light fuel oil at boilers and diesel motors.

Abstract: Abstract of the Disclosure An ultrasound liquid level detector system for automatically controlling the dispensing of a post-mix beverage, including microprocessor-controlled circuitry for monitoring and implementing the automatic dispensing process.  The microprocessor is interfaced with an ultrasonic transducer which transmits ultrasonic wave energy towards the container to be filled and receives reflected ultrasonic wave energy, the characteristics of which are analyzed within the microprocessor to implement control functions of the automatic dispensing process. Dispensing automatically begins as a container is inserted under the ultrasonic transducer into a proper position beneath a post-mix beverage dispenser nozzle. The transducer continuously measures the distance between the top or lip of the container and a liquid/foam interface of a carbonated beverage being dispensed into the container.  Dispensing stops when the transducer senses a predetermined level of carbonated beverage within the container.  In addition, dispensing is initially stopped before the liquid level reaches the top of the container to allow for dissipation of foam on the top of a carbonated beverage and dispensing is reinitiated to top off the level of beverage adjacent the top of the container. The disclosed system also utilizes the ultrasonic transducer to measure the level of ice within the container prior to dispensing and precludes dispensing of the beverage if the level of ice exceeds a predetermined limit.  The system also has additional safeguards programmed into the microprocessor to preclude operator errors such as triggering of the dispenser system by devices other than the container to be filled.

Abstract: A B S T R A C T             A blind fastener including a pin and a sleeve and having grip compensating means for accommodating workpieces varying in total thickness and having means for expanding the sleeve for filling the clearance between the fastener and associated openings in the workpieces and at the same time providing material from the sleeve in the area of expansion to define a lock between the pin and the sleeve.  The grip compensating means is separate from the pin and is generally tubular in construction with a portion adapted to provide radial deformation.  The construction is such that the pin will travel the same amount regardless of whether the fastener is used in the minimum grip or maximum grip condition.  The fastener provides hole fill over an extended portion of its grip.  The excess of the material of the sleeve that is used to provide hole fill is used to provide the material for the internal lock between the pin and sleeve.  The lock material is provided for at least between one-third to around one-half of the pin travel, i.e. the distance over which the pin extruding land engages the reduced diameter hole filling sleeve bore.  This permits the use of a substantially wide lock groove.  The fact that the groove is wide results in an increase in effective shear area enhancing the lock between pin and sleeve.  The extruding land on the pin does not act as a stop and movement of the pin is arrested by an external means such as engagement of a tool with the leading face of the guide land on the pin.
