Title: Analysing fluid flow within hollow bodies
IPC: G01T1/29
Filed: 1981-11-13
Abstract: A representation of oil flow in a hollow body such as a gas turbine engine (10) is obtained by injecting a compatible radioactive isotope label into the engine oil flow and detecting the radiation emitted from within the body with detectors (23) mounted outside the body to produce signals representative of the quantity and direction of the radiation; the detector output signals are compensated for attenuation on passing through the engine in accordance with attenuation signals derived from a representation of the spatial distribution of the engine and of its materials, and signals from non-viable directions are discounted. The compensated detector output signals are used to generate a number of focal-plane tomograms from which an image in a desired plane may be reconstructed. The image may be formed on a background of the engine in the relevant plane generated from the representation thereof. The injection of radio-active label and the detector output signals may be pulsed to produce a strobed image from which velocity measurements can be obtained. <IMAGE>

Patent GB-2100820-A (GB)
Title: Axial compensator
Inventor: BREDAHL HENNING
IPC: F16L51/02
Filed: 1981-11-10
Abstract: Changes in length of a district heating pipeline which arise as a result of temperature changes are absorbed by inserting axial compensators, said compensators being provided with a flexible metal bellows (1) secured in a gas-tight manner to each its tube piece (3, 4) inside the compensator. The variations in length which arise are taken up by the metal bellows. This construction ensures a completely closed compensator, thus preventing the ingress of water, steam and foreign matter between the tube ends, and thereby ensuring undisturbed operation of the bellows. By forming the tubes (3, 4) in such a way that they act as a telescopic guide, optimum stiffness and thus protection of the bellows is achieved. The bellows (1) is protected externally by a casing consisting of a cylinder (10) which extends between two flanges (7, 8), thus totally enclosing the bellows. Furthermore, the compensator can be provided with a pair of rails (9) having a sliding engagement with recesses in a guide (11), this guide being secured to the casing cylinder (10). This prevents torsion of the bellows during installation work, when the compensator is twisted to provide access for welding between the compensator and the district heating pipeline.

Title: Load transporting apparatus
Inventor: DICKSON-WRIGHT EDWARD ANTHONY
IPC: B65G7/06
Filed: 1982-08-27
Abstract: Load transporting apparatus enables loads to be transported on and off vehicles. The apparatus requires a loading platform to be located adjacent a load receiving surface of a vehicle. The platform and the surface each have channel shaped tracks which are aligned with one another. An inflatable tube on which is carried a plate is located in the base of the channel and skates are arranged to be moved along the plates when the tube is inflated. Thus the skates can move along the channels supporting a load when a transfer to or from the vehicle is required. When in position deflation of the tube causes the skates to lower and the load rests on the associated surface. In the deflated position the skates can be moved along the tracks out of engagement with the load. The plates have a central depression to ensure that the skates remain centrally located in the tracks.
