Title: Improvements in or relating to the separation of solid materials of different specific gravities
IPC: B03B5/30
Filed: 1944-05-26
Abstract: 584,504. Sink and float concentration. COLLIERY ENGINEERING, Ltd., LAWRIE, A. E., and NEEDHAM, L. W. May 26, 1944, No. 10205. [Class 82 (ii)] In a sink and float or gravity concentration process different parts of the raw material are treated with heavy separating media of different specific gravities respectively so that the process is carried out in a plurality of stages, the dilute medium obtained from the washing of the separated material at each stage is used in admixture with the separating medium provided in the same or another stage and/or the liquid obtained after removal of solids from the dilute medium as wash liquor in the same or another stage. As shown in Fig. 1 the dilute medium obtained from washing the separated material after a high gravity separation 1 flows by line 3 to a high gravity settler 4 the overflow from which is used for washing the separated material from an intermediate gravity separator 7. The separated material from a low gravity separation 12 is washed by the overflow from the intermediate gravity settler 9 and the overflow from the low gravity settler 14 is clarified and used as wash liquor for the high gravity separation. In a modification, Fig. 2, (not shown) the dilute medium obtained from washing at the high gravity separation is led to the intermediate gravity settler and similarly from the intermediate separation to the low gravity settler. In a further modification, Fig. 3, (not shown) the high gravity separator is fed with fresh water for washing, the circulation being confined to the intermediate and low gravity stages. In a further modification, Fig. 4, the dilute medium obtained from washing the high and intermediate gravity separator is led by lines 34 and broken lines 35 and 35a for use as separating medium in later stages while that from the low gravity separator 12 after clarification may be directed to any of the settlers, and the overflow from the settlers used as wash liquor in the same stage.

Patent GB-498814-A (GB)
Title: Improvements in and relating to process and apparatus for purification of befouled liquids, sewage and the like
IPC: B01D21/02
Filed: 1937-04-12
Abstract: 498,814. Treating sewage and foul liquids; furnaces for burning sewage sludge. HAWLEY, C. G. April 12, 1937, No. 10350. [Class 111] [Also in Group XII] In a process for purifying sewage and foul liquids, the bulkier solids are first separated by screening and the liquid is then caused to flow through an elongated tank where lighter solids are floated off and heavier solids settle, these separated matters being afterwards destroyed by combustion. Light mineral oil, such as kerosene, may be added to aid the levitation of the lighter matter. The liquid may be aerated. Standardized tanks built up of flanged metal plates and of trough-like cross-section may be used. Fig. 5 shows plant comprising two such tanks 4, 4<1> placed side-by-side. The liquid is introduced at one end of the tank 4 through straining apparatus I as described in Specification 499,021 and passes down into the tank through a wide channel 22, Fig. 8, with baffles projecting from the walls to disperse the liquid laterally. At the other end of the tank the liquid overflows into a trough 48 and is lifted as spray into a chamber A by a rotor R. Floating matter is removed by a skimming device S in the form of a bar having an inclined surface with a series of upstanding V-shaped guides. The settled matter is removed by flights 81 on an endless chain 8. The separated floating- matter, the settled sludge and the matter separated by the strainer are all passed to an incinerator D. The rotor R may be formed as a cylinder with smooth surface or may comprise a number of discs closely spaced apart on the axis. The chamber A is open at the top and has an inclined wall a' having inwardly turned steps a<2> with air admission slots below, so that the liquid is thoroughly aerated as it cascades down to collect in a trough 51. From the trough 51 it passes to a similar aerating device at the end of the tank 4<1> and then flows back through the tank 4<1> to an outlet T<1>. Matter removed by a skimming device S<1> is returned to the liquid in the tank 4. A more complicated arrangement of plant, comprising a large number of tanks 4 with connections for passing the liquid therethrough in parallel, is described. Fig. 31 shows a suitable form of sludge-drying and incinerating furnace. Sludge supplied to troughs d<3> is caused to boil by the heat of a chain d
 which passes round sprocket wheels d<7> in the troughs and hangs loosely in the chamber d of the furnace. The chamber d may have a fuel grate or an oil or gas burner d<2> . The chain carries the dried sludge as a powder into the chamber d where it is consumed. Steam rising from the troughs is condensed in a chimney d<9>. Matter separated by the strainer is supplied directly to the chains through a pipe W<1>.

Title: Rotary take-up for sewing machines
IPC: D05B49/04
Filed: 1951-05-03
Abstract: 679,353. Sewing-machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.). May 3, 1951, No. 10357/51. Class 112. Rotary take-ups.-A pair of rotary take-up elements rotate about respective fixed, spaced axes, the orbit or periphery of one lying at least partly, and preferably wholly, within that of the other. In the form shown, a pin 36 projects inwardly from a disc 34 fixed to a shaft placed above the needle-bar shaft end rotating at the same speed, and a pin 35 projects outwardly from a disc 33 rotating in the plane of the face-plate of the machine at twice the speed of the disc 34; the disc 34 and the face-plate together form a narrow thread-confining space. The shaft of the disc 33 is geared to the needlebar shaft, and that of the disc 34 to the former shaft; the shaft of the disc 34 takes part in controlling the thread, as shown. In the stitchsetting position, the two pins are moving together from their greatest spacing, and their frictional effects on the thread act in opposite directions, thus permitting the use of a lighter tension. Since the pins move towards and away from each other any broken thread tending to become wound on them will be broken; in a modification, to give better thread-breaking action in a broken thread, the disc 34 carries a second pin arranged so that it passes inside the pin 35. Specifications 656,419 and 656,420 are referred to.

IPC: H01H63/32
Abstract: 106,506. Siemens & Halske Akt.- Ges. May 4, 1916, [Convention date]. Addition to 23336/13. Automatic exchange apparatus.-Relates to selectors of the kind described in the parent Specification in which the brushes of the selector are arrested by a locking-member which is brought into the locking position mechanically by the operation of the selector and is held there by the test magnet when the terminals of an idle trunk are reached, and consists in effecting the mechanical movement of the locking-member by means of a rotary cam with easy inclines, for example a swash-plate. The selector brushes are carried by the shaft of a worm-wheel 1 which drives a worm 2 on a shaft 3 carrying the swash-plate 6. A rocking arm 9 mounted on a pivot 10 carries two springs 7, 8 engaging opposite sides of the cam 6, by which the arm 9 is rocked to and fro between the test magnets 11, 12. Two radial arms 4, 5 project in opposite directions from the shaft 3, and normally the action is such that the head 13 of the locking-member 9 is withdrawn from the path of the arms 4, 5 and allows them to rotate continuously. When, however, the selector brushes engage terminals connected to an idle line, the test magnets 11, 12 are energized and the locking-member 9 is held magnetically in one or other extreme position, so that the rotating-arm 4 or 5 is arrested after advancing further for about one quarter of a revolution. During this further advance, the spring 7 is put under tension which enables the locking-member 9 to spring away from the magnet when the latter is subsequently de-energized. The springs 7, 8 are arranged radially to the shaft 3 and are kept slightly apart by distance-pieces 14 secured to the locking-member 9. The arm carrying the head 13 of the locking-member 9 is approximately tangential to the cam 6.
