Abstract: A method is disclosed for efficiently protecting dy­namic compressors from surge under changing inlet condi­tions and in response to flow disturbances of varying size and speed. An antisurge control system based on this disclosed method will compute the relative proximity of the compressor operating point to its surge limit as a multi-variable parameter which is self-compensated for changes in gas composition, inlet temperature and pres­sure, compressor efficiency, guide-vane position, and rotational speed. A combination of adaptive closed- and open-loop control responses is used to maintain a margin of safety between the operating point and the surge limit. Both the safety margin and the magnitude of the open-loop response are proportional to the rate at which the operating point approaches the surge limit, thus maximizing process efficiency.

Abstract: A capacitively coupled printed patch (3) as a high efficiency device to couple orthogonally polarised energy between a stripline (5) and a waveguide (1). Coupling between the stripline (5) and the patch (3) is achieved by the stripline terminating in a narrow strip probe (4), the end of which lies close to, but not in contact with, an edge of the patch (3). Two separate probes (4) arranged mutually orthogonally are used to effect independent polarised couplings to produce independent linear orthogonal signals or independent left- and right-handed circularly polarised signals. The striplines (5) and patch (3) are supported on a common substrate (8) which extends transversely through the waveguide (1). The waveguide wall has a quarter-wavelength thickness (T) so that its inner edge (10) appears continuous to energy passing through the substrate (8). One application is in a DBS satellite TV receiving system where it is required to isolate two signals sharing a common channel but having orthogonal polarisations.

Abstract: A method of eliminating scattered gamma rays and collecting an image comprises the steps of detecting a radioisotope (RI) given to a living body, to form an RI distribution image, and eliminating scattered gamma rays generated in the living body or a gamma camera (1) from the RI distribution image. In this case, the energy spectrums of gamma rays incident to individual positions in the gamma camera (1) in association with pixels of the RI distribution image are collected at the same time as or during the collection of the RI distribution image. A ratio of the scattered gamma rays in respect to the RI distribution image is acquired from the energy spectrum for each position, and a scattered gamma ray component is eliminated from the RI distribution image for each pixel, by multiplying the ratio of the scattered gamma rays to the RI distribution image.

Two, spaced side curtains or panels (31, 32), which are suspended from the underside of the platform, guide fibers into a predetermined space located between opposite sides of the upper run of the screen, thereby to form the fibers into a shingle-free nonwoven mat which may, if desired, be fed successively onto the upper run of the screen in the next successive unit in a series thereof. The width and configuration of the mat can be changed by adjusting the panels toward and away from each other, and by placing a removable template (26) or baffle (75) over the suction opening.
