Abstract: A system for determining the value of a compositional parameter of blood, including a sensor for producing a signal related to the value of the compositional parameter. A computer analyzes the signal and produces an output representing the value of the compositional parameter of blood. There is a delayed response in the system such that the signal has a time-varying waveform that varies from an initial value to an equilibrated value. The equilibrated value is predicted by detecting the occurrence of an inflection point and then computing an estimate of the equilibrated value based upon the assumption that the waveform varies exponentially from the inflection point to the equilibrated value.

Abstract: The invention relates to a procedure and a device for the deburring of pipe end faces by machining. In the process, the pipe (1) to be deburred is rotated about a longitudinal axis (8) and pressed with its end face against a grinding belt (5) in such a way that the grinding direction is from the inside of the pipe to the outside of the pipe. As a result, a burr-free inner edge and secondary grinding burr on the outer edge are produced. This outer burr is then removed by the known technique of an elastic grinding tool and at the same time slight edge radiusing is produced. <IMAGE>

Abstract: There is provided an arrangement for preventing a premature ignition of an active charge, to be ignited by an adjustable delayed-action fuse, of a projectile fired from a launching barrel by an ejection charge, the arrangement being based on a mechanical and a pyrotechnic safety element. The ignition path between a first delayed-action piece ignitable during firing and the active charge of the projectile can be blocked by a tubular sensor which is displaceable transversely relative to the firing direction and which, in its position blocking the ignition path, can be retained by an acceleration sensor displaceable counter to the firing direction and, as long as the projectile is in the launching barrel, by the tubular wall of the projectile. A second delayed-action piece likewise ignitable during firing and having a delay time shorter than that of the first delayed-action piece loads the tubular sensor by gas pressure in the direction of its arming position after the expiry of its delay time. …<IMAGE>…

Abstract: A method and apparatus are described for determining the cylinder mass of air M available for combustion in a crankcase scavenged, two-cycle engine 10, based upon the Ideal Gas Law relationship and indications of pressure P, volume V, and temperature T of air in the crankcase chamber 18, at predetermined points in the engine operating cycle. This is achieved by first determining the mass of air M T  trapped and compressed in a crankcase chamber 18, and thereafter, determining the residual air mass M R  remaining in the crankcase 18 after the transfer of air to the associated combustion chamber 40. Then, the actual air mass 17 transferred to the combustion chamber is determined as a function of the difference between the trapped and residual air masses. Engine trapping efficiency can be used to correct for air leakage from the combustion chamber 40 prior to cylinder exhaust port closure. The volume of the air within the crankcase chamber 18 is derived as a function of engine cycle position, with crankcase air temperature T being derived as a function of intake air temperature T IN . Air pressure P in the crankcase 18 is monitored with a pressure transducer 46.

Abstract: A process for enhancing the dewaterability of concentrated waste sludges which have a substantial content of a water retaining cellular structure arising from microbiological action by heat treating them at temperatures in excess of about 260°F is disclosed. A preferred embodiment involves the use of treatment temperatures of less than about 390°F and consequently a treatment pressure of less than about 200 psig. The heat treatment is advantageously conducted by direct contact between the concentrated waste sludge and pressurized steam. The effect of the heat treatment may be accelerated by adjusting the pH of the sludge to an extreme value, particularly an acid value of about 3 or less. It is beneficial to neutralize the concentrated waste sludge before dewatering it and it is advantageous to neutralize before completing the heat treatment.
