Patent GB-2222560-A (GB)
Title: Road vehicle stability indicating system
Inventor: SHORT DAVID F
IPC: B60R16/023
Filed: 1988-09-09
Abstract: The stability indicating system e.g. for long articulated vehicles, container transport vehicles and tanker vehicles, includes means (14, 15) for monitoring the road speed and angle of steer of the vehicle and provides an audible and/or visual indication (12) in the driver's cab of an approaching condition of instability. The monitoring means preferably monitors not only the angle of steer but also the rate of steer and may additionally include means (16,17) for monitoring relative movements between the vehicle axles and the tractor, trailer or vehicle chassis. The warning is preferably progressive, for example, an audible warning can become louder or a visual flashing indicator can increase its rate of flashing as the instability point is more closely approached. The warning should, of course, be given sufficiently in anticipation of the instability point to give a comparatively unskilled driver the opportunity to take corrective action. <IMAGE>

Abstract: An air traffic control system 15 (Fig. 2) for a region of airspace defined by surveillance radar system 17 and a plurality of reporting waypoints formed by radio beacons 18, includes a CRT display 30 (Fig. 3) and a display pointing input device, such as a joystick and cursor, whereby displayed flight progress data 35-40 can be accessed and then amended with the aid of a displayed menu 51. The flight progress data for each aircraft has a subset formed comprising its identification, cleared flight level, next reporting waypoint and estimated time thereto. Primary sorting means (331) assigns the subsets for aircraft whose next reporting waypoints is in the controller's region but not yet accepted by him to a pending group displayed at 40 and upon aircraft acceptance secondary sorting means (332) assigns the aircraft to groups, displayed at 35-39, according to next reporting waypoint. The use of subsets enables minimal information on many aircraft to be displayed in a small screen area for scanning by the controller and the screen area occupied by each subset provides a menu-like means of addressing the data for that aircraft. The full flight progress data for any aircraft so addressed is also displayed at 46. Screen space saved through the use of subsets may contain a synthetic radar map showing waypoints 12, etc. and aircraft 56 and the display pointing device can address the data of any aircraft by pointing to its map position as well as its subset position. <IMAGE>

Title: Disposition of parts in photosensitive printers
Inventor: KOGA YUJI
IPC: G03G21/18
Filed: 1991-08-20
Abstract: In a printing device which employs a photosensitive imaging surface which is imaged by an optical exposing apparatus, the housing or casing is arranged as an upper and a lower part which are mutually openable (e.g. for maintenance), and the optical exposing apparatus is accommodated in the upper part in such manner as always to take up the same position with respect to stabilising means when the parts are closed together. Undistorted exposure is thereby ensured even when the fit of the upper casing on the lower casing is incorrect or is disturbed during printing. As described (see Fig 1) the upper housing (1) and a sub-frame (10) carrying the optical scanner (11) are separately pivoted about a common axis (3). Lugs (20) on the housing (1) engage in oversized apertures (16) in the sub-frame (11) to allow limited pivotal movement therebetween while ensuring that the sub-frame follows when the lid is opened. A spring (25) acts between the housing part (1) and the sub-frame (11), which spring serves to urge the sub-frame (11) against abutments (5) on a lower casing part sub-frame (2), whereby its position is stabilised even if the upper part (1 a) is disturbed. <IMAGE>
