Title: Improvements in or relating to automatic steering apparatus for air and other craft
IPC: G05D1/08
Filed: 1933-05-19
Abstract: 402,345. Controlling aircraft and watercraft. DEHN, F. B., 103, Kingsway, London.-(Aakania Werke Akt.-Ges. vorm. Centralwerkstatt Dessau und C. Bamberg- Friedenau ; 87 Kaiseralle, Friedenau, Berlin.) May 19, 1933, No. 14579. [Class 4.] Aircraft, submarines and other watercraft, and vehicles automatically steered or stabilized by means responsive to angular deviations of the craft about an axis and /or by means responsive to speed of turning about the same axis have means comprising a gyroscopic turn indicator so connected to the control apparatus that pressures on the precession axis which are proportional to the angular accelerations of the deviation also effect an additional compensation of the control. A gyroscope 10 having its axis normally parallel to the lateral axis of the craft is mounted in a precession frame 12 pivoted at 13 in a frame 14 pivoted about normally vertical pivots 16 in a frame 15. This frame is pivoted at 18 in fixed supports and can be clamped in any angular position to the vertical by a clamping nut 19. A curved rod 25 pivoted about the pivots 13 and connected to the precession frame 12 by adjustable springs 28 is engaged by a fork 26 connected to a jet tube 1. This tube is pivoted about a vertical axis and directs a jet of air on to two nozzles 3, 4 connected to a cylinder 7 by which the rudder or other control element is actuated. The precession pressure on the pivots 13 causes the frame 14 to move and a curved bar 29 attached to this frame positively engages a fork 30 on a vertical limb 2 of the tube 1 to add a correction depending upon the angular acceleration of the craft. A movement proportional to the angular displacement is applied to the tube 1 through a resilient connection 33 to a diaphragm 32 in a chamber controlled by a compass. Movement of the rudder also applies a follow-up correction to the jet tube 1 by means of the cable 34, lever 35 and spring 36. In order to compensate for movements about axes at right angles to the axis about which the control is being effected, the frame 15, which has a pointer moving over a scale 22, is set at an angle to the vertical so that, e.g., a correction is applied to the steering control when the machine tilts about a longitudinal axis. For control about the longitudinal or lateral axes a pendulum may be used to apply the correction for angular displacement.

Filed: 1969-03-21
Abstract: 1,263,998. Mixing apparatus. LUWA A.G. 21 March, 1969 [25 March, 1968], No. 15024/ 69. Heading B1C. [Also in Division F4] Flowable materials (unspecified) are distributed as a thin film over a heated or cooled wall surface by a spreader member which moves relatively to the wall surface. As shown, a plurality of spreader members 36 are axially spaced (either uniformly or not) along a shaft 38 which is reciprocated axially so that the spreader members pass over the inner surface of a shell 12. The flowable material enters the shell through an inlet 20 and ports 24, and flows downwardly as a film over the wall 12 to an outlet 26. The action of the spreader members on the film as they reciprocate across the wall as shown in Figs. 2 and 3. The wall is heated or cooled by a fluid circulated through a surrounding jacket 14. A rotary motion may be superimposed upon the reciprocating motion of the spreaders and this is said to improve the distribution of the flowable material. The spreader elements 36, as shown, comprises rings which when heating of the flowing material is involved, permit the escape of vapour to an outlet 28 at the top of the shell. A modified spreader is described (Fig. 6) which accelerates the escape of vapour from the surface of the film and also removes any entrained droplets in the vapour. The spreader rings may be such that in one direction of their reciprocating motion they scrape the film from the surface. Another form is described (Figs. 7-10) in which the film runs over the outer surface of a cylindrical member (88) through which passes the heating or cooling fluid. The spreaders are reciprocated over the cylindrical surface and incorporate means to separate droplets from the vapours generated in the flowing film and to guide the vapours towards the wall of a surrounding casing where they may be condensed by a cooling coil (120) and guided back into the film. The spreaders may be stationary, the relative motion being applied to the wall.

Title: Production of phosphorus oxychloride
IPC: C01B25/10
Filed: 1953-06-03
Abstract: Phosphorus oxychloride is prepared by treating phosphorus trichloride with gaseous oxygen in the presence, as catalyst, of orthophosphorous or orthophosphoric acid, preferably in an amount within the range 0.015 to 0.4 per cent. by weight of the phosphorus trichloride. Orthophosphorous acid may be produced in situ by the addition of water or humidified air, for example, by the addition of 0.01 to 0.2 per cent. by weight of water (equivalent to 0.015 to 0.3 per cent. by weight of orthophosphorous acid).  Increased pressures of from 2 to 25 pounds per square inch or more are preferably employed.  The reaction temperature may range from 0 to 100 DEG  C. or higher.  At 0 to 5 DEG  C. the phosphorus trichloride may be simply shaken in the presence of oxygen.  At 50 to 70 DEG  C. or higher the oxygen should be introduced below the surface of the liquid and thoroughly incorporated therewith, for example, by extremely turbulent agitation, or the phosphorus trichloride may be sprayed into an oxygen atmosphere.  The oxygen employed is preferably substantially free from nitrogen.  The process may be batch or continuous.
