A torsional vibration damper for mounting on a shaft comprises a driving member 10, Fig. 1, with a radial flange 12 for attachment to the shaft, a driven inertia member 16, 16a resiliently supported at 26, 27 on the driving member and provided with an annular cavity 18 to contain a viscous fluid, and a portion 23 on the driving member extending into the cavity so that a fluid film between the portion and the cavity partly absorbs the torsional vibrations. The driven member consists of two sections connected by rivets 17, the cavity 18 being provided with fill passages 21 and sealed by a gasket 22. Rubber or a similar material may be injected into the space between the driving and driven members before or after curing so as to be in a state of radial compression. In an alternative construction, the sections of the driven member are held together by an annular band having its outer marginal portions deformed into grooves in the sections, an inwardly directed central radial flange on the band forming the base of the cavity 18. Fig. 4 shows a construction in which the driving member has two outwardly flanged portions 32a, 33a while the driven member has two cast or otherwise formed sections 34, 36 of ductile material, the section 34 having a flange 41 extending around the section 36 and enclosing under pressure a sealant in a groove 43. The portion of the driving member which extends into the cavity of the driven member is slotted to provide fingers 49 extending alternately in opposite directions so that a frictional facing 51 is urged into engagement with the side faces of the cavity. Cooling fins 44 may be provided. The portions 32a, 33a may be frusto-conical, instead of curved, and the flange for connection to the shaft may be formed in a manner similar to that shown in Fig. 1, while the sections of the driven member may be connected by a ring of ductile or other metal, sealing being effected by material trapped under the ring or by a separate ring of elastic material. In Fig. 9, a section 94 of sheet metal or cast in ductile material is secured in an annular depression in the driven member 92 to form the cavity 93. In a further construction, the driving member has a pair of members with end flanges arranged back to back to sandwich the portion extending into the cavity of the driven member while the latter has a pair of sections with opposed chamfers to form a space for an elastic sealing ring held in place by a circumferential band.

Title: An improved process for refining petroleum distillates
IPC: C10G29/20
Filed: 1937-12-24
Abstract: A process for sweetening sour mineral oil distillates consists in removing the mercaptans by (a) converting them into copper mercaptides, and (b) extracting these by a selective solvent such as an alkylamine or an alkylolamine.  The oil may be previously washed with a dilute aqueous solution of alkali such as sodium carbonate solution to remove hydrogen sulphide.  Sour gasoline is agitated with ammoniacal cupric sulphate solution until the mercaptans are converted to copper mercaptides.  The mixture is allowed to settle till two layers are formed.  The oil layer is drawn off and agitated with a 10 per cent volume of ethanolamine. On allowing to stand, the gasoline and amine layers are separated. The gasoline layer gave a negative test for mercaptans when treated with sodium plumbite solutions.  After treating with copper salt solution, the gasoline may be partly distilled at a temperature below the decomposition temperature of the mercaptides, and the still bottoms then treated with alkyl amine or alkylol amine to dissolve out the mercaptides. The distillate and extracted parts are then blended.  Instead of ammoniacal copper sulphate solution, a solution of the copper sulphate or other salt in the extraction agent may be used.  The process may be carried out with batches or as a continuous counter current process.

Filed: 1967-08-07
Abstract: 1,201,242. Electroluminescence. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 7 Aug., 1967 [15 Aug., 1966; 27 Oct., 1966 (3)], No. 36218/67. Heading C4S. An infra-red to visible image converter comprises an electroluminescent layer, an infra-redquenchable photoconductive layer (e.g. CdS), electrodes, an A.C. source, a visible bias light source to induce a bias photo-current and means for projecting a visible light on to the photoconductive layer to induce a photo-current greater than the bias photo-current to erase the after-image of the incident infra-red image. The bias light may be provided by a second electroluminescent layer, an external light source or may be omitted, in which case the decaying photo-current of the after-image eliminating light may serve as bias photo-current (e.g. Fig. 6, not shown). A light (23) of variable intensity may serve alternately as bias light and afterimage eliminating light source (Fig. 2, not shown) or rotating slotted discs, or a stroboscope may be used to periodically radiate the device with the after-image eliminating light, to obtain moving displays for instance (Fig. 3, not shown). The infra-red radiation may be interrupted at intervals or may be continuously incident. Also, to reduce flicker, the A.C. supply to the device may be periodically terminated during after-image elimination by mechanical switching (Fig. 4, not shown) or by a photo-cell-relay mechanism in combination with a rotating slotted disc, for example (Fig. 5, not shown). Alternate interruption of the radiation from continuous infrared and after-image eliminating light sources may be achieved by pairs of discs slotted in opposite senses (Fig. 7, not shown).

Abstract: 994, 522. Doffing spinning &c spindles; coupling cop-tubes to spindles. E. NEGISHI. Sept. 25, 1962 [Oct. 30,1961], No. 36347/62. Heading D1D. [Also in Division B8] Means for doffing a spinning &c. machine comprises a series of two-armed levers each rotatable about a central pivot arranged on a ring-rail or spindle-rail and disposed between a pair of adjacent spindles so that at the time doffing each lever is rotated to engage the lower ends of the associated bobbins and lift them off their spindles. As shown, levers A 1 A 2 ,Fig. 5 are pivoted at 4 on a ring rail which is moved to effect the build, and each is pivotally linked at 5 to a bar B which when moved to the left causes the levers to swing to the positions shown where they engage beneath the bobbins 11. The bar B can be operated by a forked member 7, Fig. 4 carried by the ring-rail which is rocked between two oppositely-inclined positions as the rail descends and brings its arms 9,10 into contact with members 16,17 on a shift bar 15. Bar 15 is moved to left and right by a member 21, Fig. 5, to which it is pivoted which can be rocked about a pivot 18 as a cam 19 is rotated through 180 degrees at a time. The bobbin is attached to the spindle by a magnet M attached to the top of the spindle and a correspondingly-shaped member N of magnetic material inside the bobbin. At the end of a build, the ring rail is at c Fig. 1 and is lowered, the member 7 being inclined to the right and member 17 vertically below arm 10. At the point d arm 10 engages member 17 and as the rail continues to e member 7 is rocked to the position shown in Fig. 4 so that bar B assumes the position shown in Fig. 3 to bring levers A 1 ,A 2 under the bobbins. The rail is now raised to f so that the bobbins are raised relatively to the spindles being guided by the lappets until the latter reach the end of their travel whereupon the bobbins are caused to topple off the spindles on to a conveyer. During this upward movement of the rail, to point f, the cam 19 is rotated to shift bar 15 and bring member 16 below arm 9 and move member 17 clear of arm 10, so that as the rail is lowered, the member 7 is rocked to bring the levers A 1 ,A 2 to inactive position.
