Patent GB-2201773-A (GB)
Title: Determining thermal history
Inventor: PILLHOFER HORST
IPC: G01N33/20
Filed: 1987-12-09
Abstract: The thermal history, of a metal alloy specimen, (particularly the maximum temperature to which it has been subject) is evaluated by examining an etched surface at a number of grid points 1 by a scanner 2 controlled by a computer 6. The presence or absence of a particular phase (the  gamma ' phase) is monitored at each grid point and the volumetric proportion of that phase is derived and correlated with e.g. the maximum temperature according to a linear relationship previously determined from known standards. The method is useful for determining whether a turbine blade has been subjected to excessive temperatures which would invali- date a guarantee, for example. <IMAGE>

Title: Thermocouple assembly
Inventor: HOLLIDAY CHRISTOPHER IAN
IPC: H01L35/20
Filed: 1988-02-15
Abstract: A thermocouple has an outer metal sleeve 1 with an insulating mineral filling 40 that supports thermocouple junctions 11 to 13. A wire 20 extends from a first terminal 5 to the forward end of the sleeve 1 where it branches into shorter wires 21 to 23 of the same material which extend rearwardly by different distances to the respective junctions 11 to 13 from which wires 31 to 33 of material of the opposite polarity extend in parallel to a second terminal 6. The output across the two terminals is a measure of the average temperature of the region R over which junctions 11 to 13 are located. The different resistance between the two terminals 5 and 6 via the different junctions 11 to 13 that would otherwise be produced, because of the difference in resistivity of the two materials forming each junction, is compensated by varying the diameters of the wires 31 to 33 or 21 to 23. <IMAGE>

Title: Processor for radar system
Inventor: ARAMBEPOLA BERNARD
IPC: G01S13/90
Filed: 1988-11-09
Abstract: In a synthetic aperture radar system the radar pulse echo return signals are sampled, which samples are correlated with a replica of the original signal to produce range line samples with increased resolution in the range direction. To increase resolution in the azimuth direction, a series of range lines are correlated or combined in some other way with Doppler or other reference coefficients. A problem with this is that there is relative movement between any particular point on the ground and the radar system, and the samples in the range lines corresponding to that position lie on a slant line such as 103 (skew axis y). To utilise the incoming data, the skew axis is arranged in a saw-tooth form. To facilitate processing, data is fed into an input sequence of data storage location, in for example a buffer 51, at a variable starting posttion which moves corresponding to each discontinuity in the zig-zag, so that the discontinuities are transparent to the processor. In one embodiment, azimuth processing can take place along columns in bands 83 in a two-dimensional memory 53, corresponding to swaths on the ground 101.   <IMAGE>

Title: Elevator group control responding to subjective feelings of users
Inventor: MORITA YUZO
IPC: B66B1/20
Filed: 1991-02-15
Abstract: Supervisory control of a group of elevators serving a plurality of floors employs the input of qualitative requests or "feelings" of the user, concerning elevator running parameters. Qualitative requests concerning elevator running are set in the form of feeling (or request) targets (102). For example, users may declare a preference between rapid arrival time and total numbers of passengers carried or between speed of journey and reduced car crowding. This information may be input using a questionnaire technique or a so-called "radar" plot where conflicting parameters are plotted around a circle. A knowledge based system can be used to evaluate the input parameters on the basis of the circumstances of the building. time of day etc. The thus set request targets are converted into control targets for elevator (103) and group supervisory control is executed using the control targets (104). <IMAGE>
