Title: Method of tamping railway-track ballast and devices for implementing the method
IPC: E01B27/16
Filed: 1963-02-06
Abstract: 1,027,802. Railway track-packing machines. MATISA MATERIAL INDUSTRIEL S.A., and CONSTRUCTIONS MECANIQUES S.A., RENENS. Feb. 6, 1963 [Feb. 8, 1962], No. 4918/63. Heading E1G. In a method of tamping railway track ballast wherein at least one pair of co-operating tamping tools D, D<SP>1</SP> (Fig. 1) embedded in the ballast is moved from a spaced-apart starting position towards one another whilst vibrating them, the amplitude of the vibrations applied to the tools D, D<SP>1</SP>, as distinct from the frequency thereof is so modulated as to be less as the tools approach the end of their travel than at the start. Controlled modulation for the or each pair of tools D, D<SP>1</SP> is got by applying vibrations to the pivotal axis of a joint of the toggle bars AB, AB<SP>1</SP> along the bisecting axis (through A, A<SP>11</SP>) of the angle between them, so that when they are set at 80‹, the amplitude of the vibrations received at B, B<SP>1</SP> is virtually zero but increases as they are set at lesser angles, connecting the ends B, B<SP>1</SP> symmetrically to the respective tools D, D<SP>1</SP> of the or each associated pair and selectively adjusting the pivotal axis at A along the bisecting axis to vary the angle L at which the vibrations are applied thereat. A device V supplies vibrations at A and a jack X moves the joints and device V in bisecting the angle L and is on the mobile chassis of a ballast-tamping machine embodying the tools D, D<SP>1</SP> and the modulating mechanism. The jack X simultaneously moves the tools D, D<SP>1</SP> inwards, the toggle-bar ends B, B<SP>1</SP> transmitting vibrations and motive force to the tools.

Title: Pyrophosphoryl tetramide, condensation polymers of pyrophosphoryl tetra-amide and n-octa-alkyl pyrophosphoryl tetra-amides
IPC: C01B21/082
Filed: 1957-02-14
Abstract: Pyrophosphoryl tetra-amide, N-octa-alkyl pyrophosphoryl tetra-amides, and condensation polymers of pyrophosphoryl tetra-amide are prepared by reacting pyrophosphoryl tetrachloride with ammonia or a dialkyl amine in the liquid phase under anhydrous conditions.  If the P2O3Cl4 is added slowly and dropwise in stoichiometric amount to liquid NH3, P2O3(NH2)4 is formed, but if the P2O3Nl4 is added rapidly in less than the stoichiometric amount the polymer (P2O3N3H5)x is formed, which may be isolated by washing out NH4Cl with water.  If liquid NH3 is used to wash the polymer, then NH3 is absorbed with formation of (P2O3N4H8)x.  The reaction may be carried out in a solvent where amines, e.g. dimethyl- or diethyl-amines, are used.  In examples: (1) P2O3Cl4 is added dropwise to liquid NH3 an the mixture is filtered and washed free from NH4Cl to leave P2O3(NH2)4; (2) a solution of P2O3Cl4 in dry ether is added dropwise to an ether solution of (CH3)2NH cooled to - 40 DEG  C. with constant stirring and cooling, excess (CH3)2NH and ether are distilled off, and (CH3)2NH.HCl is filtered off to leave liquid P2O3(N(CH3)2)4 which may be redistilled; (3) P2O3Cl4 is added dropwise to (CH3)2NH cooled to - 70 DEG  C., excess (CH3)2NH is distilled off, and (CH3)2NH.HC removed by filtration to leave the octamethyl derivative of (2); (4), (5) less than the stoichiometric amount of P2O3Cl4 is added rapidly to liquid NH3, excess NH3 is distilled, and NH4Cl is washed out with water to leave (P2O3N3H5)x or liquid NH3 to leave (P2O3N4H8)x.ALSO:N-octa-alkyl pyrophosphoryl tetra-amides are prepared by reacting pyrophosphoryl tetrachloride with a dialkyl amine in the liquid phase under anhydrous conditions.

Title: Improvements in or relating to stabilizing devices for the pivoted aerofoils of aircraft
IPC: B64C13/00
Filed: 1929-02-18
Abstract: 329,648. Vickers (Aviation), Ltd., and Pierson, R. K. Feb. 18, 1929. Steering, balancing, and regulating altitude.- A stabilizing device for the large pivoted aerofoils of aircraft, is so constructed and arranged as to exert a stabilizing or restoring force upon the aerofoil during its angular movements when the aerodynamic forces on it are unbalanced, to relieve the aerofoil of this force at or near the angle of incidence at which the aerodynamic forces on the aerofoil are more or less unbalanced, and to maintain the aerofoil free of this force at greater angles of incidence. Such a device is shown diagrammatically in Fig. 1 and applied to a rudder in Fig. 6. A triangular plate A is connected at its apex to the control cable B and is arranged to rock about one of two fulcra C, C<1>. A short link D is pivoted to the plate at D<x> and to a longer link D<1> at D<2>. The latter is acted upon bv a spring E through a rod E' pivoted to the link at D<1x>. When the aerofoil is moved angularly the plate A is caused to rock upon one or other of its fulcra C, C<1> and the apex of the plate is thereby lifted, compressing the spring E. The links are so arranged that the moment of the spring decreases with increased movement of A until link D<1> abuts against a stop F at which point D<2> coincides with C or C<1> and the moment of the spring is zero. From this point on to the limits of its movement, which are set by the stops G, the plate A, and hence the aerofoil, are not acted upon by the spring. Fig. 6 shows how a, casing H upon which the device is mounted may be adjusted to set the aerofoil when in its central position, as determined by the stabilizer, parallel to the air current. An alternative form comprises a slidable member connected to the control cable, which carries a roller disposed between two spring-operated cam members.
