Title: Text processing device
IPC: B41J3/50
Filed: 1979-03-27
Abstract: A text processing device employs a typewriter (T,DrSt, D, SW) in association with a storage device (Sp, SpSt) in which information input via the typewriter keyboard (T) can be stored and which controls the print-out device (DrSt) of the typewriter as and when required in accordance with the stored information. For text processing, the originally printed original provided with handwritten corrections can be reinserted in the printer (D, SW); when a starting position has been reached in which the text section located at the print-out position of the printer device and the storage device agree with one another, a control connection (via Z) is established so that when a change occurs in the position of the printer relative to the data carrier the corresponding location in the store (Sp) is automatically selected. <IMAGE>

Title: Improvements in Interpolation Methods and Apparatus
IPC: H04N1/60
Filed: 1980-06-30
Abstract: The invention relates to methods and apparatus for interpolating between coarse stored data to achieve a more accurate answer, and is particularly applicable to colour scanning reprographic equipment. Colour scanners (5) analyse an original to obtain digital signals (8) representing three primary colour intensities. The values for the intensities of each of four printing colours, including black, are functions of all three primary colour intensities, and a limited quantity of these sets of four values is stored as a three dimensional matrix (25), consisting of cubes with values at their corners. To obtain values from these coarse stored data corresponding to a point (P) within a cube, an interpolator (26) determines which one, of the three pyramids (e.g. W B G C V in Figure 2) comprising the cube, contains the point, and interpolates within that pyramid between the values at its five vertices. <IMAGE>

Abstract: Light-tight hood 16 fits over a standard road lamp, turning it on if it is controlled by a light sensitive switch. Light dependent resistor 32 is mounted against hole 26 in the hood opposite a lens enclosure of the lamp, to receive light therefrom. When the lamp flashes, light emitting diode D1 flashes in synchronism, indicating correct operation. If the power of the lamp is below a first predetermined level, such that the batteries would be likely to fail if left over a weekend, this is detected and light emitting diode D3 is turned on. If the power of the lamp is below a second, lower predetermined level, such that the batteries would be likely to fail if left overnight, light emitting diode D3' is turned on. <IMAGE>

IPC: B64C21/02
Filed: 1980-11-26
Abstract: To induce lift on a conventional aircraft wing during vertical take-off, landing, or hover, rearward flow is induced over the inboard half of the wing by blowing air at 2 through slots at the rear of a leading edge flap, and forward flow is induced over the outboard half of the wing by blowing air at 6 through slots at the front end of trailing edge flaps, with boundary layer suction at 3 ahead of the trailing edge flap of the inboard half and at 7 behind the leading edge flap of the outboard half to reduce flow separation over said flaps.
