Title: Improvements in and relating to devices for damping the oscillations of rotary shafts and the like
IPC: F16F15/121
Filed: 1929-11-21
Abstract: 335,807. Junkers, H. Nov. 21, 1929. Flywheels.-In a device for damping torsional vibrations of rotary shafts wherein vanes rotatable with the shaft can move, under the restraint of fluid friction in liquid containing cavities in an otherwise free flywhel member, the radial boundaries of the cavities are inserted separately, and are preferably flexible, to facilitate accurate fitting. A flywheel 6 is formed in two parts 5, 5<1> centred on the boss of a disc 3 keyed to the shaft and carrying a series of vanes 4 each of which fits with a small amount of play into cavities in the parts 5, 5'. The cavities are formed by first drilling circular holes 9 and machining out the annular space 16, the semi-circular axial grooves thus remaining forming boundaries for radial walls 10 which may take any of the forms shown in Fig. 10, wherein the members are flexible and press outwards against the walls of the grooves. Member 34 is flexible both longitudinally and transversely. The interior is filled with liquid preferably oil through a central hole in the shaft and a hole 11, and vibration of the shaft causes the liquid to be forced from one cavity to the next through narrow, resistance offering gaps 13. The partitions 10, are in sliding contact with the steel disc 3 and are made of material of good running properties in relation to it, e.g. cast iron, or to obtain high elasticity, bronze. The chamber-forming annular recesses 16 may be formed on cylindrical, conical, or other rotational surfaces.

Abstract: 848,913. Stripping waste from bobbins. MOOS, K. Nov. 26, 1956 [Dec. 20, 1955], No. 36059/56. Class 120(3). Waste thread is removed from weft bobbins 4 by feeding them successively by an automatic conveying device to a thread loosening device 17 which partially unwinds the thread while the bobbin is rotated in the unwinding direction, past a stream of compressed air which forces the loose thread end downwards towards a thread removal device 27, 28, and past the removal device which removes residual thread while the bobbin is being rotated about its own axis. As shown, bobbins are supplied by a conveyer 5, Fig. 1, to a magazine 6, trailing threads being removed by automatic scissors 7. Entrance to the magazine and passage therethrough are each controlled by a bobbin detector 11 with a mercury switch 12 to prevent bobbin accumulation at these points. The magazine feeds to a slotted guide 2, comprising rails 2a, 2b, Figs. 3, 4, on which the bobbins are supported by their heads and along which they are moved by conveyer belts 14b, 14c which roll them along rail 2b in the unwinding direction of rotation. When a bobbin is opposite a thread-loosening disc 17, its linear motion is halted for several revolutions about its axis by an oscillating stop finger 20, Fig. 3, a further linked finger holding the following bobbin; during this rest period, the bobbin is pressed by a plate 18 against the foam rubber facing 17<SP>1</SP> of disc 17 which unwinds a length of the residual thread, assisted by a stream of compressed air from a pipe 26. When the bobbin is released it is fed between deflector sheets 34 past stripping rollers 27, 28. A stream of air from a tube 33 extends the unwound thread to facilitate its entrance between rollers 27, 28 which strip the residual thread and drop it past a deflector plate 41 into a container. A brake strip 36 fixed to one deflector plate steadies the bobbins opposite air tube 33, and a foam-coated bar 38 stabilises the bobbins over rollers 27, 28.

Abstract: Dicalcium phosphate dihydrate, CaHPO4 2H2O, is produced from phosphoric acid and/or a phosphoric acid salt, a calcium compound and, if desired, a basic compound, by a process comprising introducing the calcium compound and the phosphoric acid and/or phosphoric acid salt, in the presence of water, into a reactor, and rapidly and intimately mixing them therein at temperatures below 70 DEG  C., adjusting the reaction mixture to a pH value of 2.0 to 6.0 and maintaining the pH value during the greater part of the reaction, by regulating the introduction of the feed compounds so that the pH value is maintained, wherein to produce CaHPO4.2H2O formed of relatively small grains within a given range of grain, the reaction is carried out at a relatively high pH within the range specified, and for larger grains it is carried out at a lower pH value within that range, and wherein after the introduction of all of the phosphoric acid and/or all the phosphoric acid salt, the balance of the other starting materials is added to the reaction mixture while increasing the pH value of the said mixture, which is then treated for the separation of CaHPO4.2H2O from the accompanying liquid.  For instance, grain sizes within the range 5 to 40m  are obtained by conducting the reaction at a pH of about 3 and grain sizes smaller than 15m  are obtained when the pH is 5. Specified feed compounds are thermal phosphoric acid, potassium diphosphate, CaCO3, Ca(OH)2, CaCl2 and Ca(NO3)2.  The optional basic compound is e.g. an alkali metal or ammonium hydroxide, carbonate or orthophosphate. Stabilizers such as tetrasodium pyrophosphate, magnesium pyrophosphate, sodium tripolyphosphate, disodium metasilicate and disodium metaborate may be incorporated in the product by introduction at any stage of the process before final separation of the product. Examples are given of the production of CaHPO4.2H2O by discontinuous and continuous processes employing as the feed compounds (i) CaCl2, H3PO4 and NaOH, (ii) CaCO3 or Ca(OH)2, and H3PO4, (iii) CaCO3, CaCl2, H3PO4 and NaOH, (iv) CaCl2, H3PO4, monosodium tripolyphosphate and NaOH or (v) Ca(NO3)2, H3PO4 and aqueous ammonia.
