Abstract: 1,087,153. Grounded flight trainers. GENERAL PRECISION SYSTEMS Ltd. Nov. 12, 1964 [Dec. 13, 1963], No. 49396/63. Heading B7W. [Also in Division G2] In an aircraft flight simulator a vertically hung terrain model 20, to a scale of <SP>1</SP>/ 2000  of the full size, is viewed by a mirror 19, which, through field lenses 18, 17, 16, objective 12 and an image rotator consisting of mirrors 13-15, produces an image on the photocathode 10 of an image orthicon television camera 11. The model 20 is moved in the Y direction and the camera assembly is moved in the X direction (not shown) and Z direction. Rolling or banking is simulated by rotation of the image rotator 13-15 about the optical axis, pitching is simulated by rocking of mirror 19, as indicated at P, and yawing, by rotation of the optical system, as indicated at H, in which case the tube 11 may be rotated as well but is usually fixed and an additional movement is imparted to the image rotator 13-15. A space between S<SP>1</SP> and A allows additional effects to be introduced, such as mist or sky effects, which can appear to be anywhere between the viewer's eye and infinity. When the mirror 19 closely approaches the model 20 a focusing device may be actuated which is mounted in position A<SP>1</SP> (see Division G2).

Title: Improvements in or relating to speed-control circuits for commutator motors
IPC: H02P25/14
Filed: 1967-10-31
Abstract: 1,139,320. Automatic control of speed. HEBERLEIN & CO. A. G. Oct.31, 1967 [Nov. 1, 1966; March 20, 1967], No. 49434/67. Heading G3R. In a system for controlling the speed of a commutator motor supplied from an A. C. source by adjustment of the firing angle of a controlled rectifier, e. g. a thyristor, in which a triggering capacitor 17 is charged by a fast rising "pedestal" voltage and then by a slowly rising "ramp" voltage, the capacitor is connected to the point 14 of a voltage divider 10, 11, 12 across which is applied the sum of a constant voltage (from Zener 8) and a speed representative voltage. The "pedestal" voltage comprises the constant voltage minus the volt drop across 10: when the voltage on capacitor 17 reaches this a diode 15 blocks and charging continues by the "ramp" voltage which is the constant voltage applied through a high value resistor 19. Desired speed is set on variable resistor 12, which determines the magnitude of the pedestal voltage. As shown, the motor is a shunt machine having a field 2 shunted by a "flywheel" diode 7. The armature 1 is energized through a single thyristor 3 and the speed representative voltage is the back e. m.f. during the non-conducting half cycles. The thyristor is triggered directly by a unijunction transistor 18. In an alternative embodiment Fig. 2 (not shown) the motor is a series machine energized during both half cycles through back to back thyristors triggered by a transformer whose primary is in series with a unijunction transistor across a diode and resistor bridge. The triggering capacitor is also across this bridge, which provides for a triggering pulse in each half cycle. The speed representative voltage is provided by a tachogenerator. Either embodiment may additionally have current limit circuits. In Fig. 4 (not shown) there is one for limiting normal running current, in which excessive current charges a capacitor sufficiently to cause a transistor to conduct which increases the volt drop in resistor 10 and so retards the firing angle; this circuit has a long time constant, and starting current is limited by a separate circuit comprising an R C delay network which restricts the rate at which the pedestal voltage can rise. In Fig. 5 (not shown) these two functions are combined in a single limiter circuit comprising an R C network connected through diodes to the junction of resistors 11 and 12 and across the Zener diode.

IPC: B01J27/19
Filed: 1967-11-06
Abstract: 1,195,037. Production of aliphatic dinitriles. IMPERIAL CHEMICAL INDUSTRIES Ltd. 23 Oct., 1968 [6 Nov., 1967], No. 50335/67. Heading C2C. Aliphatic acyclic dinitriles are obtained by contacting a gaseous mixture comprising cyclohexane or cyclohexene, singly or in admixture, ammonia and oxygen with a solid catalyst comprising a compound of antimony or molybdenum and oxygen, at an elevated temperature, in the presence of a halogen at the catalyst surface. The presence of a halogen at the surface of the catalyst may be induced either by doping the solid catalyst with a halogencontaining compound, e.g. an inorganic halide, or by incorporating a volatile chlorine-, bromine- or fluorine-containing compound in the feed gases. The reaction is generally effected at a temperature of 300-700‹ C. employing a ratio of hydrocarbon feed to ammonia of 1: 3 to 7: 1, and a ratio of oxygen to hydrocarbon feed of 1: 3 to 8:1, and an inert gas and/or water vapour may also be present. The process is preferably operated on a continuous basis with mean gas feed/catalyst contact times of 0À4-5 sees. The antimony-containing catalyst, which may be present as the trioxide, tetroxide or pentoxide or mixtures thereof, may also be employed in admixture with one or more other metal oxides which may take the form of separate metal oxides or they may be present in chemical combination with the antimony oxide. The molybdenum-containing catalyst, which is molybdenum oxide or a molybdenum compound capable of yielding molybdenum oxide when heated in oxygen at 450-650‹ C., is advantageously employed with an acidic material, e.g. an oxide of phosphorus, arsenic or boron, as a promoter. The catalysts, which may be prepared by conventional methods, may be employed alone or admixed with inert diluents or carriers, and are preferably pre-heated before use. Specific examples describe the production of adiponitrile, succinonitrile and glutaronitrile.
