    Abstract: 1377076 Stabilized optical systems OPTICAL RESEARCH & DEVELOPMENT CORP 29 Oct 1971 45896/71 Heading G2J To stabilize an optical system, a lens C 1 (and in the embodiment illustrated a further one C 2 ) is arranged in a fluid filled cavity B and is of neutral transparency. It is biased by ring magnets 90 acting on the magnetic ring 70 (additionally extra magnets 91 and the "tethers" 94 may be provided for wind restraint). The optics are such, formulae are given in the Specification, that the optical path through the assembly is independent of the deviation from the horizontal, the initial movement of the fluid in the chamber acting as a compensating force.

    Abstract: The present invention concerns apparatus for analyzing flowable substances such as slurries using techniques such as X-ray fluorescence, infra-red reflectance or emisson spectrography. The material to be analyzed is caused to flow over a plate in a very thin film so that a quantitive measurement of the elements of interest in the material can be made by analytical systems.

    Abstract: A miniature pressure transducer of particular application in surgery is mounted at the tip of a catheter and operates to cause movement of a liquid-gas interface in a capillary tube in response to pressure on the deformable wall of a liquid-filled reservoir. The interface position is sensed in terms of electrical parameters and communicated through the bore of the catheter to external measurement apparatus.
