Abstract: 370,455. Twisting and winding artificial silk. PARCOFIL AKT.-GES., 20, Peterstrasse, and SCHWEIZER, E., 10, Neum³hlequai, both in Z³rich, Switzerland. Jan. 8, 1931, No. 717. [Class 120 (ii).] To maintain a uniform twist when twisting and winding artificial silk the drive of the machine is varied so as to compensate for irregularity due to the varying diameter of the delivery-bobbin as well as to compensate for that due to the varying diameter of the winding-bobbin. The entire compensation may be effected in the drive of the winding-bobbin, or the compensation in respect of the deliverybobbin may be effected by driving it at a speed which increases as its diameter decreases. The winding-mechanism may be adapted for winding cylindrical bobbins with conical ends, or those in which the diameter varies during each traverse, such as conical bobbins, or weft and bottle bobbins. As applied to a machine, such as described in Specification 370,454, for winding conical bobbins, wherein a spindle shaft 12 is coupled to a swash-plate shaft 11 which is driven from friction gearing 6 through eccentric wheels, and ratchet gearing 13, 14 driven from the swash-plate shaft serves to reduce the winding-speed by adjusting the gear 6 by means of a lever 19 in accordance with the growth of the bobbin 5, the ratchet gearing is arranged further to decrease the winding-speed in accordance with the decrease in the diameter of the delivery-bobbin 9, or the lever 19 is arranged to move the belt-fork of cone driving-mechanism and increase the speed of the delivery-bobbin.

Title: Method of making chlorine dioxide
IPC: C01B11/02
Filed: 1948-01-09
Abstract: <PICT:0639085/III/1> Chlorine dioxide is made by reacting sulphur dioxide, preferably diluted with inert gases such as air or nitrogen, with an acid solution of a water-soluble chlorate, the chlorate solution being substantially saturated with the sulphate of the cation of the chlorate whereby sulphate will crystallize out of itself as it is formed during the reaction, and adding more chlorate to the solution according as its is used up in the reaction. Chlorates specified are sodium, potassium, ammonium, calcium and magnesium. The sodium sulphate which is formed may be the only solid in the reaction vessel.  According to one embodiment, sodium chlorate solution acidified with sulphuric acid (or other strong acid such as phosphoric acid) in vessel 1 is treated with combustion gases from a pyrites burner introduced through the perforated end of a tube 3, from which bubbles rise upwardly through the tube 2 and cause circulation of the solution within vessel 1.  The chlorine dioxide formed escapes through a pipe 4 together with inert gases from the pyrites burner.  The reaction temperature is maintained at 30 DEG  C. by cooling coils 5, and the sodium sulphate formed crystallizes out as Na2SO4.NaHSO4.  Solution and crystals are pumped to a centrifuge 9 from which solution passes to a dissolver 11, in which sodium chlorate is added to the solution.  Here, the solution is kept at 40-50 DEG  C. and is agitated by means of air introduced at 15, and finally returned to the reaction vessel 1.  It is stated in the Specification to be known that the chlorate concentration may be kept high during the reaction by using liquid in the reaction mix to such an extent that only the chlorine dioxide formation is possible, the reaction mix, which must be vigorously agitated, remaining solid or pasty.

Patent HK-27590-A (HK)
Title: Dynamoelectric machines
Inventor: UHEN RICHARD FREDERICK
IPC: F16J15/54
Filed: 1990-04-12
Abstract: A lubricant slinger mechanism for preventing the loss of oil or other lubricant which is pumped between the rotor shaft and bearing in an electric motor or other dynamoelectric machine. The slinger is mounted to the rotor shaft and mounted adjacent the end of the bearing out of which oil flows as it is pumped along the shaft from the reservoir. The slinger initially throws the oil radially outward against an inner oil well cover, and the provision of an impeller, such as a spiral vane on the outer peripheral surface of the slinger, imparts an axial component of velocity to the lubricant which impels it rearwardly toward the reservoir and prevents the migration of oil out of the forward end of the oil cover through which the rotor shaft extends. The slinger, in one form, includes an annular cup portion which overhangs the end of the bearing so that lubricant is thrown off the slinger at a point rearwardly of the end of the bearing. The slinger is preferably formed with an opening that is larger in diameter than the shaft and includes a tapered surface on one end so that as the brass rotor sleeve is inserted into it, it centers the slinger and enables the brass sleeve to be pressed therein by means of automatic assembly machinery.
