Title: Improvements in aircraft tail chassis
IPC: B64C25/50
Filed: 1932-12-23
Abstract: 390,469. Aeroplane-tail wheels. ROSATELLI, C., 37, Via Po, Turin, Italy. Dec. 23, 1932, No. 36505. Convention date, July 18. [Class 4.] In an aircraft-tail chassis of the kind in which a rotatable fork carrying a wheel is connected with means tending to maintain the wheel in position in a determined vertical plane and to restore it to this position after displacement therefrom, resilient means are adapted to exert a couple having a magnitude substantially above zero at said position of the wheel and increasing even with small displacements of the wheel in order to ensure effective resistance to such displacements and positive restoration of the wheel to the said position. In one form, a tail skid 1, Fig. 3, is carried by a fork 2 pivoted in tubular member 3 to which are joined frame members 4, 5 of which 4 are articulated to the fuselage whilst 5 are connected to shock absorber 6 which is, in turn, articulated to the fuselage. A sleeve 8 is mounted at the upper end 7, Fig. 5, of fork 2 which sleeve may be coupled or uncoupled to part 7 at the will of the pilot through distant control mechanism. Sleeve 8 is formed with an arm 8<1> which with an arm 14<1> of a corresponding member 14 supports a pin 16. Bellcrank levers 12, 13 shaped as shown in Figs. 4 and 6, are freely mounted on sleeve 8 between arms 8<1>, 14<1>. Forwardly extending arms 12<1>, 13<1> of levers 12, 13 normally abut on pin 16 whilst resilient members 18, Fig. 4, are connected to the outwardly extending arms of the levers. A stop member 17 forms a fixed abutment for loose levers 12, 13. When sleeve 8 is coupled to part 7 of fork 2 rotation of the latter causes rotation of one or other loose lever by its engagement with pin 16, the other lever being held against stop 17 by its associated tension member. Lateral movement of the wheel is thus resisted by the full tension of one member 18 which always tends to restore the wheel to its central position defined by stop 17. Sleeve 8 is uncoupled for manoeuvering the craft on the ground at low speeds. Fairings 26, 27 enclose tail wheel chassis and tail wheel. In a modification, Fig. 9, a lever 28, shaped as shown, fast on part 7 actuates loose levers 29 normally held against stops 30 by tension members 18. Here again lateral turning of wheel 1 only causes extension of one member 18. In a further modification, Fig. 14, loose arms 34 are coupled to part 7 of fork 2 by one-way clutches. Each lever is formed with a spiral track terminating in a tooth 33 adapted to be engaged by a spring pressed detent 31 when fork 2 is rotated in the appropriate sense.

Title: Removal of iron values from aluminium sulphate solutions
IPC: C01F7/748
Filed: 1963-09-18
Abstract: The iron values in aluminium sulphate solutions containing dissolved ferric iron impurities are removed by intimately contacting, e.g. countercurrently, the said solution with a weak base secondary amine liquid anion exchanger with a basic dissociation constant of at least 1 x 10-5.  The organic and aqueous phases may be separated and the aqueous phase containing iron-free aluminium sulphate removed.  The weak base secondary amine liquid anion exchanger, e.g. "Amberlite" (Registered Trade Mark) may be in the sulphate or bisulphate salt form, and dissolved in a water-immiscible organic solvent, preferably kerosene or heptane.  The iron impurities dissolved in the aluminium sulphate solution may initially be converted to the ferric form with an oxidizing agent, e.g. hydrogen peroxide. The aqueous phase may be purified from undesirable odour imparted by the organic solvent with activated charcoal or an oleophilic organic pigment.  An alcohol containing more than 8 carbon atoms may be added to the anion exchanger as a surface active agent.

Abstract: 781,494. Fluid-pressure servomotor-control systems. BENDIX AVIATION CORPORATION. Dec. 21, 1954, No. 36973/54. Class 135. A device for actuating, e.g. an indicator or a valve member in response to a fluid temperature change comprises a pressure responsive means 21<1> operatively connected to the member, means including a fluid circuit for establishing a pressure differential variable with temperature variation in the fluid including a fluid-flow orifice 16<1>, a thermal element 11<1> connected to a valve 141 for varying the effective area of the orifice, a vent 22<1 >to a low-pressure source downstream of the orifice, and means for imposing the differential pressure on the pressure responsive means, the effective area of the vent being such that the product of the pressure differential and a given orifice area is greater than the tensile load exerted by the valve on the thermal element. Fluid moving into the scoop 27 creates a high pressure PH via passage 23<1> in chamber 191 outside the bellows 211. Movement of the valve 14<1> by the element 11<1> produces a variable pressure PM inside the bellows via passage 18<1> having the variable or fixed vent 22<1> leading to a region of low pressure PL.
