Title: Stabilising and safety device for aircraft
IPC: F04F1/06
Filed: 1932-01-16
Abstract: 393,687. Aircraft. OEHMICHEN, E. E., 16, Rue de Villiers, Valentigney, Doubs, France. Jan. 16, 1932, No. 1380. Convention date, Jan. 17, 1931. [Class 4.] A heavier than air machine, particularly a helicopter, is combined with a balloon containing a light gas or atmospheric air which while normally rigidly fixed to the body of the machine may be instantaneously separated therefrom, carrying with it the occupants, the dimensions of the balloon being such as to permit of its maintenance in the air or its return to the ground at a reduced speed. As applied to a helicopter, Figs. 1 and 2, a frame 4 fitted with horizontal propellers 5 and tractor propeller 6 is secured by hooks 8 to cleats 10 on a cradle 3 of a balloon 1. The occupants are carried by a pyramidal car 2 located in a recess 2<1> in frame 4. The hooks 8 are pivoted to swing about horizontal axes and may be rocked simultaneously to release the frame 4 by the lever system shown in Fig. 2, which is arranged at one side of the car 2. The frame 4 is further connected to the balloon 1 by cables 15 wound on a pulley 19 mounted in frame 4 at one side of the car, the cables being guided by pulleys 17, 21. An adjustable brake 22 acts on drum 19 which is normally held fixed by a pawl 24 engaging a ratchet wheel 25 fixed to the drum. If the machine is falling the lever 13 may be operated to release the frame 4 a few meters above the ground, lever 13 is also arranged to release the pawl 24, thus the frame 4 separates from the balloon and cables 15 unwind from the drum; whilst the frame strikes the ground violently the balloon and the occupants fall much more slowly owing to the aerostatic buoyancy of the balloon, or may remain in the air if the buoyancy is sufficient. The cables 15 may disengage auto. matically from the drum or may remain fixed thereto when fully unwound, in which case they include resilient means and the releasing operation may be carried out at a greater height since the balloon continues to retard the fall of the frame. The brakes may be automatically regulated so as progressively to reduce the rate of rotation of the drum after half the cable has unwound. In single-seater machines the pilot may be attached to the balloon by harness. The balloon may be fitted with equatorial parachutes. Means for absorbing the shock of landing of the car, Fig. 4, comprise tubes 26 terminating in bases 27 and carried on slides 28. These tubes are normally supported in the position shown by hooks engaging heads 37 on. the tubes. These hooks are disengaged on detachment of the car by interconnections with the operating rods of hooks 8, thus permitting the tubes 26 to fall to the position 26<1>, Fig. 1. Friction brake means comprising shoes 30 actuated by springs 32 are normally held out of engagement with the tubes by wedges 34. The heads 37 of the tubes strike wedges 34 on falling, and cause engagement of the brake shoes which thus provide a powerful resistance to upward movement of the bases 27 and tubes 26 on contact with the ground.

Title: Process for clarifying and preserving liquids containing colloids
IPC: A61L2/238
Filed: 1934-01-19
Abstract: Liquids containing colloids are treated with oligodynamic metals in such quantity that, after absorption of some of the metal by the colloids and flocculation of the colloids, sufficient metal is present to sterilize the liquid.  The treatment with metal may be in two or more stages with separation of the flocculated matter by decantation or filtration between the stages.  Soluble compounds of the oligodynamic metals may be added to the liquid or the liquid may be exposed to a current between electrodes of such metals.  Excess of the metal may be removed by physical, chemical or electro-chemical means.  The process is stated to be applicable for the treatment of fruit juices, beer, wine, coffee extract, spirits, vinegar and pharmaceutical extracts, such as valerian or frangula.  In the case of vinegar the sterilizing effect of the oligodynamic metal may be assisted by that of sulphur compounds, such as sulphides, sulphites, bisulphites, hydrosulphites, pyrosulphites and thio-sulphites. Oligodynamic metal may be recovered from the separated flocks. Specifications 325,796, [Class 49], 353,409, and 384,466 are referred to.ALSO:Liquids containing colloids are treated with oligodynamic metals in such quantity that, after absorption of some of the metal by the colloids and flocculation of the colloids, sufficient metal is present to sterilize the liquid.

Filed: 1941-02-17
Abstract: 582,932. Spark-gaps. JONES, F. L. Feb. 17, 1941, No. 2093. Drawings to Specification. [Class 39 (i)] [Also in Group XXVII] A high-voltage spark-gap especially suitable for aircraft ignition systems comprises a gasfilled air-tight envelope in which the electrodes are sealed and rigidly supported and are so disposed that a uniform electric field is maintained over a substantial fraction of the sparkgap volume; the electrode material has a work function greater than 4.0 electron volts<1>; and the product of the pressure p and distance d apart of the electrodes is greater than five times the value of this product which corresponds to the minimum sparking potential of the gas. Very short breakdown times are obtained, ranging from 10-<4> to 10-<10> seconds. The preferred electrode materials are tungsten, molybdenum and platinum. The filling may be nitrogen or hydrogen; for aircraft the preferred filling is nitrogen at 50-100 cms., preferably 70 cms. Rare gases may also be used, with precautions against metastable states, but metallic vapours should be avoided. The electrodes in the preferred form illustrated are flat discs with rounded edges sealed into a hard-glass envelope by tungsten rod supports. The ratio of diameter to distance d should exceed 10, and d should be greater than 0.2 mm. and may be as great as 1.5 mm. Cooling is provided to reduce thermionic emission, which tends to prolong the spark, although a small degree of emission may be desirable to increase the reliability of breakdown. The whole envelope may be immersed in an oil-bath. The gap may be used for radio circuits.
