Filed: 1949-03-11
Abstract: 662,659. Spray producers. DEFENSOR AKT. GES. March 11, 1949. No. 6790/49. Class 69 (iii). A liquid is formed into a fine mist (aerosols) by being fed to one or more rotary discs, the film so formed being projected outwards towards a disintegrator containing apertures and subsequently against baffle and guide surfaces. In Fig. 1 liquid mixture from a container 16 is drawn up a passage 7, spreads across rotor discs 6 and is flung against curved vanes 10, the mist being drawn from a chamber 1 by a fan 11 leading to one or more outlets. A motor 3 drives the shaft 5 carrying the rotor 6 and the fan 11 ; the fan may be adjusted along the shaft. Ambient air enters the chamber 1 through inlets 1b. The vanes 10 may be adjustable, have their upper surfaces shaped parabolically, made in rake-like fashion, or be formed of pins or wires of highly elastic and resilient material. Vibrations of very high frequency may be imparted to the vanes. In place of the vanes, a ring may be provided, containing slots of varying width. A skirt 17 around the inlet nozzle, prevents splashing. The cross-section of the inlet 7 may be varied and the fan 11 adjusted to alter the quantity of mist produced, particularly if it is used for inhalations. The mist may be heated or cooled. The fan may be made of rubber and other parts of the apparatus of plastic material. The aerosold may be charged with electricity particularly when used in disinfection, control of parasites and the like. Quartz lamps 20 may be used to submit the aerosols to ultra-violet irradiation or ionisation may be produced by a condenser on the motor 3. Infra red irradiation may be used to treat the aerosols. For the production of ozone the aerosols can be treated by quartz lamps or spark discharges. Agents, such as alkyl-sulfonic acid salts, alkyl-sulphuric acid salts or condensates of ethylene-oxide, may be used for reducing the surface tension of the aerosols. The active components of the liquid to be atomised may consist of fixed aldehydes, e.g. dioxymethal-carbamide or of the following: N Oxymethyl-carboxylic acid amides, N Oxymethyl sulphonic acid amides, or of aromatic compounds containing the hydroxyl group, or of compounds containing the -oogroup, or of substances liberating oxygen, or of chloramine and chloramide, or of glycols.

Title: Improvements in and relating to aircraft cabin pressure control arrangements
IPC: B64D13/04
Filed: 1945-03-19
Abstract: 589,201. Automatic control systems for aircraft cabins. BRITISH THOMSONHOUSTON CO., Ltd. March 19, 1945, No. 6854. Convention date, March 20, 1944. [Class 38 (iv)] Fluid pressure control.-In an arrangement for controlling the air pressure in an aircraft cabin, compressed air, controlled by a valve 14, Fig. 1, is fed into a cabin 12 via a conduit 13 and discharged via a restriction 18 and a valve 17. Between altitudes 10,000 and 35,000 feet the pressure is maintained constant by means of a bellows 29 connected between the restriction 18 and the valve 17 and co-operating with a similar but evacuated bellows 33 containing a spring, to move one end of a switch arm 25 in accordance with the absolute pressure in the cabin and so control a reversible servomotor operating the outlet valve. The effect of measuring the pressure between the restriction 18 and the valve 17 instead of in the cabin is to prevent hunting. At an altitude of 35,000 feet a bellows 37, responsive to altitude pressure, expands and a spring 41 begins to act on the other end of the lever 25 to effect a drop in the pressure as shown by the part CD, Fig. 2. At the altitude represented by the point D, the spring 41 is fully compressed and a pin 40 engages with the lever 25, thus, at higher altitudes, the valve 17 is responsive to changes in the of cabin pressure to altitude pressure.

Abstract: 797,528. Fluid bearings. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 14, 1956 [March 16, 1955], No. 7714/55. Class 12 (1). A shaft 1 is surrounded by a sleeve 2 having a clearance therewith and air from three jets of radius rj, equally spaced around the periphery, flows into three cavities 3 and escapes through orifices at the outer ends of the cavities 3. The air pressure in each cavity exerts a varying restoring force on the'shaft the phase of which is so arranged that the force has maxima which coincide with velocity maxima of oscillation of the shaft and tends to oppose the oscillation. In a modification, the radial clearance between the shaft and the sleeve is enlarged which has the effect that the shaft is attracted towards each of the jets. In another modification, shown in Fig. 12, the air supply to each of three shallow cavities 3 formed in a sleeve 2 is controlled by a pneumatic amplifier consisting of a spring- pressed diaphragm 5 which responds to pressure variations in cavity 3 with a lagging phase shift. Air from cavity 3 leaks into a cavity 9 behind the diaphragm 5 through a central hole 10 in the diaphragm 5. Fig. 14 shows a further modification in which no central hole in the diaphragm is provided but increased damping is effected by an additional resistance and cavity network 11 ... 14 connecting the cavities 3 and 9. In the construction shown in Fig. 18, the air supply to each cavity 4 has a branch 15 leading to a calibrated orifice 16 through which air is admitted to a recess 17 in the wall of the sleeve. Figs. 20 and 21 show an embodiment in which two sets of cavities 3 and 17 and their associated resistances 20 and jets 16 are disposed around the circumference of the sleeve and another similar arrangement is located axially alongside it and turned round through an angle of 90 degrees.
