Title: Electromagnetic door lock
Inventor: CLARKE WALTER WILSON HUGH
IPC: E05C19/16
Filed: 1985-11-07
Abstract: A door lock of the type which makes use of an electromagnetically generated force for holding fixed and movable parts together. The locking comprises a fixed part (10) for attachment to a door frame (12) and a movable part (14) for attachment to a door (16). The fixed part (10) includes a ferromagnetic plate (32) and a solenoid coil (30). The movable part (14) includes a tubular 30 collet (42), which is fixed at one end relative to the door (16), and a tapered ferromagnetic plug (44) disposed longitudinally within the collet (42) such that energisation of the coil (30) causes the door (16) to be held in its closed position by magnetic attraction between the tapered plug (44) and the fixed plate (32). However, when the door is pulled in an opening direction from its closed position, the free end of the collet (42) is arranged to be caused to ride up the taper of the plug (44) whereby the collet is expanded radially outwardly to bring a projection (48) thereon into engagement with a stop (50) fixed relative to the door frame (12), thereby to prevent further opening movement of the door (16). <IMAGE>

Title: Preparing maps
Inventor: KIDNEY PAUL
IPC: G06T17/05
Filed: 1990-01-02
Abstract: In a method of making a map, data collected by remote sensing, such as satellite image data 41, is processed 42 to provide an image of a selected region. Feature data representing geographical features within the selected region is digitised 43, compared 44 with the satellite image data and corrected for distortion. The two sets of data are then integrated 48 in such a way that each element of image data for which there is a corresponding element of feature data which serves to define a feature is modified to provide a new element of combined data, so that, following the data integration step, there is incorporated information pertaining to features as defined by the digitised feature data. 
<??>Data integration may alternatively be achieved by printing 45 an image of the region using the image data, tracing 46 therefrom the required feature data, and digitising 47 and inputting this data into stage 48. A further stage 52 may enable the incorporation of text data, e.g. from a typeset film 49a or by direct input 49b, into the integrated feature and image data. 
<??>The final output is in the form of master separations 53 suitable for colour printing, and provides a product in which an integrated appearance of image, feature and text data is achieved without any suggestion of overlay printing.
