Title: Improvements in flexible mountings for aircraft engines
IPC: B64D27/04
Filed: 1934-12-01
Abstract: 451,577. Aircraft engine supports. PAULSEN, J. F., 6, Rue Francois Gaillard, Viroflay, Seine, and STRACHOVSKY, N., 31, Rue le Marois, Paris, both in France. Dec. 1, 1934, No. 34528. [Class 4] [See also Group XXVI] A flexible mounting for an aircraft engine comprises plate members adapted to be connected to the engine and its support respectively. These have flat surfaces lying in planes perpendicular to the crank-shaft axis and are connected by elastic or resilient material between them. The contact is limited to the flat surfaces, the outer surfaces of the edges of the plates being free. The elastic material is in shear and provides radial and angular elasticity, but limits axial displacement. In the construction shown in Fig. 2, the engine 1 is secured to the support 2 by plates 4, 5 with elastic material, e.g. rubber, between and permanently secured to the plates. The supports are arranged radially in a plane perpendicular to the engine shaft or to an axis passing through the centre of gravity of the engine. Five mounts are shown in a fivecylinder engine. In the construction shown in Fig. 8, the rubber packing 3 is secured to plates 4 and stamped plates 12. The plates 4 are secured to the engine by screwed rods 8, nuts, and sleeves 11. The plates 12 are secured to the plates 5 by bolts 15, and these are bolted to the aeroplane &c. framework. The sleeves 11 engages the walls of holes 13 and limit the displacement. If the rubber 3 breaks or deteriorates, the plates 4 prevent disengagement of the supports. The mounts 3, 4, 5 are distributed uniformly around the axis of the crank-shaft or around an axis parallel thereto. Inelastic steel balls 14, Fig. 4, may be inserted in the packing-elements 3 to limit the axial displacement. In a modification, Figs. 10, 11, 12, the support plates 5<1> are circular and bolted together. Elastic and metal plates 31, 4<1> are mounted between them. The plates 41 are provided with lugs 20 which pass through recesses in the plate 51 which permit angular play, and carry sleeves which support the engine. The ring 4<1> limits transverse displacement. A single element 3 may be arranged between two plates 4, 5. A plurality of plates may be carried by the engine and support respectively with packing elements between. The elastic plates may be of different hardness or consistency so that longitudinal displacement is different for compression and tension.

Abstract: 1322108 Programmed control of machine tools BENDIX CORP 26 July 1971 [5 Aug 1970] 34877/71 Heading G3N The motion of a cutter relative to a rotary spindle is controlled by a system, responsive to a source of numerical path information, wherein the spindle speed is modified by a signal which is a fraction of the distance of the cutter from the axis of rotation of the spindle. As shown, a punched tape 30 is fed through a reader 32 to derive input information blocks to a controller 34 providing signals to control a lathe 36. The control signals determine the movement of a cutter 42, by X, and Z axes phaseanalog serves 44. 46, through D.D.A. interpolators 48, 50. The output pulse rate of the interpolators is determined by a feedrate interpolator 52 as a function of a fractional feedrate number provided by the controller on a line 56 and a pulse train generated by a transducer, associated with a spindle drive 38, on a line 58. The feedrate number is derived from a programmed 1PR value and the incremental cutter path calculated as the square root of the sum of the squares of the X and Z axis incremental for a block. The X axis pulses are also fed to a radium store 62, maintaining a value proportional to the normal distance of the cutter from the workpiece axis of rotation, the contents of which are divided into a programmed cutter to workpiece surface speed value to derive a value proportional to a desired speed. The appropriate gear range is selected by an AND-gate, not shown. For gear-cutting a marker pulse generator, not shown, is used through a gate circuit to initiate spindle pulses at a set point in the spindle rotation.

Title: Improvements in or relating to the manufacture and treatment of materials made of or containing organic derivatives of cellulose
IPC: D01F2/28
Filed: 1930-11-20
Abstract: Artificial filaments, ribbons, horsehair, straw, and the like are made by causing an organic solution of cellulose acetate or other organic cellulose derivative containing a compound of sodium or potassium with ricinoleic, stearic, or oleic acid, or of an alcoholic amino body such as triethanolamine with a fatty acid, to set under such conditions that this wetting agent or soap is retained in the products.  Fine denier filaments may thus be made, and the products are very pliable and have a low scorching and high melting points. They are either of subdued lustre or may readily be delustred by water or aqueous baths; if relustred by ironing while damp, they may again be delustred by warm water. The wetting agent may amount to 1,5 to 10 per cent of the weight of the cellulose derivative; in an example a solution for dry spinning contains 25 parts of cellulose acetate, 73 of acetone, and 2 of potassium ricinoleate.  The spinning atmosphere may be heated air, nitrogen, or carbon dioxide.  For wet spinning, the bath may consist of water or dilute sulphuric acid.
