Abstract: ABSTRACT     In a method of ultrasonically measuring the thickness between opposed surfaces of a workpiece from one surface, a velocity parameter of ultrasonic longitudinal waves through the material of a workpiece is measured at a location along a first surface of the workpiece.  Ultrasonic longitudinal waves are transmitted from one surface to the opposite surface, and the ultrasonic waves reflected from the opposite surface are received and a time parameter between transmission of the longitudinal waves and reception of the reflected waves is measured.   The thickness between the opposed surfaces is determined from the measured velocity parameter and the measured time parameter.  a device for measuring the thickness of a workpiece from one surface includes a transducer assembly with a pair of spaced apart transducer units each having a coupling member and a piezoelectric element mounted thereon. a third coupling member has a pair of piezoelectric elements mounted thereon, and an electrical circuit connected to the piezoelectric elements for control and measurement. The piezoelectric element is mounted on the first coupling member of one of the pair of transducer units at a predetermined angle relative to the bottom surface to generate a subsurface longitudinal ultrasonic wave through the workpiece to be tested and to be received by the other piezoelectric element of the pair of units.  The measuring device further includes apparatus for supplying couplant medium to the interface between the bottom surface of the coupling members and on the workpiece, and means for supporting and moving the transducer assembly along the workpiece.

Abstract: ABSTRACT     A high speed cylindrical nuclear magnetic resonance (NMR) sample spinner includes a housing to which pressurized air is supplied.  A cylindrical stator is mounted within the housing and is adapted to support a receiver coil.  There are spaced along the length of the stator a number of circumferentially spaced openings through which the pressurized air is transmitted from the housing to the interior of the stator.  A solid to be analyzed by nuclear magnetic resonanc? is placed within a rotor and the rotor is inserted into the stator.  The rotor is supported within the stator by the pressurized air transmitted through one or more of the openings formed in the stator.  The rotor is driven by a turbine-shaped end cap which is responsive to the air supplied through other of the openings formed in the stator.

Abstract: ABSTRACT      The head for the hydrostatic detection of the level com-prises a main enclosure divided by a membrane into two chambers, one of which communicates with a supply of air under pressure, while the other is connected to a probe that is immersed deeply in the liquid by an auxiliary enclosure also containing a primary chamber that communicates with the inlet of the gas under pressure, and a secondary chamber separated from the primary chamber by a membrane forming one piece with a valve mounted between the secondary chamber and a small connecting pipe, which prevents any ill-timed rise of the liquid inside the device, in the case of the disappearance of the compressed air supply, and which makes it possible, at the same time, to install the detector head above the tank.

Abstract: MEASUREMENT SYSTEM OF ENHANCED RELIABILITY          ABSTRACT OF THE DISCLOSURE    As a means   to enhance the reliability of a measurement system and render the measurement system tolerant of failure, the method which comprises tripling the component elements of the measurement system, for example, providing three thermo-meters to measure one and the same temperature and selecting a correct measured value by the logic of decision by majority has found popular recognition in the art.  This method, however, entails many problems such as increased cost, increased weight, and increased volume because it necessitates the component elements thereof to be tripled.    This invention, owing to the addition to the measure-ment system of a check signal generator adapted to produce a check signal which is the linear combination of functional values of physical quantities under measurement, enables the measurement system to materialized detection of failure, identification of the site of failure, and recovery of a correct measured value by feeding the produced check signal in parallel with the former measured values into a computer and causing the computer to perform prescribed arithmetic operations by using the check signal and the measured value.  Thus, the invention enables the measurement system to acquire enhanced reliability of performance and improved tolerance  against failure by the incorporation of de-cisively few redundant component elements as compared with the conventional method which necessitates the component elements to be tripled.

Abstract: ABSTRACT OF THE DISCLOSURE     In order to be able to run a gas turbine engine with pulverized coal as fuel on an industrial basis an arrangement is provided for utilizing the energy contained in the bypass flow with the help of which the solid combustion particles in the combustible gas are removed prior to its entry to the gas turbine blading. If the engine is used for an aircraft this arrangement consists of a thrust nozzle (12) impinged upon by the bypass flow which augments the action of the main thrust nozzle (7). For use in a stationary power plant this arrangement consists of a heat exchanger in which the heat of the bypass flow is utilized. Thus no unused energy gets lost by way of the bypass flow, so that the heat exchanger need not be kept extremely small for enonomic reasons. The result is a well cleaned combustible gas and the blades of the gas turbine (5) are to a large extent protected from erosion caused by combustible residues.
