Abstract: 1,251,876. Aircraft simulators. SINGER-GENERAL PRECISION Inc. 27 Aug., 1969 [5 Sept., 1968], No. 42657/69. Heading B7W. [Also in Divisions G2-G3] An aircraft simulator film display system uses films with a frequency modulated signal corresponding to the original aircraft speed magnetically recorded on the films. In the simulator, the film 12 is advanced relative to the projection system 20, 21 by a sprocket 18 connected to the drive 26 of a motor 24 and a tachogenerator 28 provides a first feedback signal to the amplifier 32 controlling the motor 24. A second feedback signal is obtained from a discriminator 44 which receives the output from a magnetic reading head 42 which senses the recorded signal, the discriminator signal being combined at the input 48 of an amplifier 56 with a signal from a computer 10, which calculates the aircraft speed corresponding to the manner in which the simulator is controlled, and with a constant signal supplied to a terminal 54 corresponding to zero speed of the recording camera. The output of the amplifier 56 is then fed, along with a constant signal from a terminal 64 corresponding to the exposure film frame rate, to the input of amplifier 32, i.e. to the rate servomechanism described above. A method of ensuring that the computed position of the simulator corresponds to apparent position displayed by the film is also described in which the recorded signal is amplitude modulated at a point corresponding to a fixed point on the ground and a detector 74 provides a pulse when the film 12 displays this point. The timing of this pulse is compared with the timing of a similar pulse from a comparator 84 which gives such an output when the coordinates of the simulator computed by a velocity integrating circuit 80 correspond to the co-ordinates of the fixed point as stored in a device 86; a signal to speed up or slow down the film is then sent back to the terminal 48 at which the other signals are combined.

Abstract: 1,265,269. Semi-conductor devices. ARBEITSSTELLE FUR MOLEKULARELEKTRONIK. 2 Dec., 1970, No. 57267/70. Heading H1K. In an I.C. comprising a pair of complementary bipolar transistors produced by diffusion into a substrate, epitaxial growth, redistribution diffusion and surface diffusion steps, that one of the transistors which has its collector and emitter of the same conductivity type as the substrate and epitaxial layer has its base region in the form of a buried ring (4) surmounted and contacted by a surface region (10), the ring serving to define the portion of the substrate and epitaxial layer which forms the collector region. As shown, P-type buried ring 4, isolation frame 6 and collector region 5 and N+ type collector contact 3 and base contact 2 are formed by diffusion in an N-type Si substrate 1. An epitaxial layer 8 is then grown, and the diffused regions 1 are redistributed into this layer and the surface is provided with a thermal oxide layer 9 which is used as a mask for the diffusion of P-type base region 10 and surface isolation frame 11. N+ type emitter region 12 and base contact region 13 and P + type emitter region 14 and annular base contact region 15 are then formed by diffusion. A layer of Mo is then evaporated on and etched to provide top surface contacts and a layer of bonding glass is applied by cathode sputtering. A handling wafer 20 of oxidized Si is then thermocompression bonded to the glass layer. The thickness of the wafer is then reduced by grinding, polishing and etching the lower face to expose the buried regions and this surface is then provided with an SiO 2  layer 22 over which suitable interconnections are provided, the positions of the buried regions being determined by an I.R. microscope technique. Resistors may be produced simultaneously with the P-type buried layers 4, 5, 6 and/or base region 10. Diffused interconnections between the two sides of the wafer may also be provided.

Abstract: 1,265,498. Suppressing a pulse from a train. PLESSEY CO. Ltd. 9 March, 1970 [26 April, 1969], No. 21425/69. Heading H3T. A circuit for suppressing a single whole pulse from a pulse train comprises two bi-stable circuits and two gates arranged substantially as shown. Normally, both bi-stables are in a reset state which maintains both AND gates open so that the pulse train applied at I passes to output O. A suppress command signal at C primes bi-stable B2 to allow it to be set and sets bi-stable B1 to allow the next trailing edge of the input train to set-B2. This closes gate G1 and blocks the next pulse. The trailing edge of this pulse, however, resets B2 so that gate G1 is opened and the following pulse passes. The command signal lasts long enough for this sequence to be completed and after this it is terminated to reset B1. Using the trailing edge of the pulse train to switch B2 prevents a pulse being split if the command starts during a pulse.
