Title: Method and apparatus for coalescing
IPC: B01D17/022
Filed: 1976-04-09
Abstract: 1530690 Coalescing liquid droplets; separating oil and water MARINE CONSTRUCTION & DESIGN CO 9 April 1976 [10 April 1975] 14594/76 Heading B1D Droplets of a first liquid suspended in an immiscible second liquid, e.g. oil in water, are coalesced by ingesting the mixture into the voids of a porous, resiliently compressible and expansible matrix, e.g. foam plastics, immersed in the compressed state in the mixture, the ingestion occurring as the matrix expands from the compressed state whilst immersed in the mixture, holding the ingested mixture in the matrix in a quiescent state until all or substantially all of the droplets have settled and coalesced in the voids of the matrix and thereafter discharging the ingested liquids from by matrix by applying pressure. The matrix may be moved from a first ingestion station to a second purging station whilst the ingested mixture is settling therein. Figure 3 shows an apparatus for effecting the process comprising a casing 10 containing an upright cylinder 32 of framed polyurethane mounted for rotary motion. The cylinder 15 surrounded around a major arc by a stationary cylindrical shield 16 against which the cylinder 32 forms a sliding seal. A roller 64 compresses the polyurethane cylinder as it rotates as the part of its surface not covered by shield 16. Incoming mixture from inlet 73 is ingested by the re-expanding polyurethane cylinder and is carried by it, as it rotates, around to the other side of the roller whereat the mixture containing coalesced droplets is squeezed from the cylinder by the roller 64. A scraper mechanism 56 provides a seal to separate the inlet and outlet sides of the apparatus. Coalesced oil is removed by an upper outlet 80 and water flows under a baffle 84 to an outlet 86. As an alternative (Fig. 9 not shown) an elongated, vertically-mounted, endless band of polyurethane may be used instead of the cylindrical element 32. The apparatus is of use in oil refineries or for treatment of engine cooling water discharge and ships bilge or ballast waters.

Title: Process for the production of pure glucose oxidase
IPC: C12N9/04
Filed: 1965-04-06
Abstract: A process for the production of purified glucose oxidase comprises mixing aqueous mycelium material containing glucose oxidase and impurities including catalase with ammonium sulphate to precipitate the glucose oxidase, separating the precipitate and dissolving it in water, contacting the solution with a weak anionic ion-exchange material which adsorbs the glucose oxidase and impurities, then selectively removing pure glucose oxidase. The solution of the precipitate may be dialysed to remove salts and then adjusted to pH about 4.5 before contacting it with the ion-exchange material.  The impurities may be removed first from the resin by eluting with a first buffer solution, and then the pure glucose oxidase by eluting with a second buffer solution.

Title: Improvements in roasting zinc sulfide ores
IPC: C22B1/10
Filed: 1957-05-10
Abstract: Cadmium, lead, arsenic, antimony, tin, germanium, and mercury sulphides are removed from finely-divided zinc sulphide ore concentrates by agglomerating the concentrate into particles between 4 and 65 mesh (Tyler), charging the agglomerates into the upper portion of a columnar fluidized bed and introducing air into the lower portion of the fluidized bed in an amount at least 5 per cent, preferably 15-35 per cent, in excess of that theoretically required to combine with the zinc sulphide component of the charge.  This air also fluidizes the bed.  A gaseous fuel in amount at least sufficient to consume the excess air is introduced into the upper part of the bed, but a substantial distance below the surface, thus maintaining in the upper part of the bed an atmosphere non-oxidizing with respect to the sulphides.  The bed is maintained at at least 900 DEG  C., preferably between 900 DEG  and 1100 DEG  C., by recycling some of the roasted ore, or by immersing water coolers in the bed.  Roasted zinciferous particles are withdrawn from the bottom of the bed, and roaster gases containing the volatile sulphides, as enumerated above, and the sulphur values from the zinc sulphide as SO2, are withdrawn from the top of the bed.  A small proportion of the roasting air may be used to purge the zinciferous particles as they are withdrawn before it enters the bed.  The term gaseous fuel includes liquid fuels which are gaseous at the temperature of the bed.  The fuel may be natural gas, refinery cracking gas, butane, or a gas such as producer or coal gas, or a vaporized fuel oil by charging fuel oil directly into the column.  In an example, zinc sulphide concentrates are agglomerated with bentonite, sulphite liquor, and water, dried and roasted, as described above.  Specification 661,560 is referred to.

Title: Improvements in or relating to belt conveyors
IPC: B65G47/31
Filed: 1958-05-09
Abstract: 843,480. Endless-belt conveyers. SMITH, J. H. W., and BALDWIN, D. T. R. May 9, 1958 [May 10, 1957], No. 14948/57. Class 78 (1). In a conveyer system for carrying articles, e.g. bundles of newspapers, in which a conveyer 1 feeds the articles on to a second conveyer 5 in controlled, spaced or timed relationship, the second conveyer travels more rapidly than the first and means is provided, which is-actuated by each article after it has left the first conveyer, to stop the feeding of further articles on to the second conveyer until the first - mentioned article has left it. The belt 1 carries rollers 3 for supporting the articles and permitting movement of the belt below them when they are stopped. These rollers are mounted in pairs in cradles 4 attached to the belt. The second conveyer consists of a pair of narrow belts 5 and a wider belt 12 between them. A vertically-movable stop 14 is disposed at each side of the belt 1 in the path of the articles and is connected to one end of a bell-crank lever 15, 16, the other end of which carries a roller 18. This roller bears against a cam 19 fast on a shaft which is connected by bevel gears to a shaft 20. This shaft is connected by chain-and-sprocket mechanism to a' shaft 28 which is connected by similar mechanism to a shaft 25. Gates 23, 24 are fast on the shafts 20, 25, respectively. If the gate 23 is at right-angles to the position shown in Fig. 1, it is engaged by the leading article and turned, thereby rotating the cam 19 to project the stop 14 into the path of the next article. When the article nears the left-hand end of the belts 5, 12, it is discharged by a push-bar moving across the belts and moves the gate 24 to a position at right-angles to that shown. The movement of the gate 24 causes the gate 23 to return to the position shown in Fig. 1 and the stop 14 to be retracted. In a modification the gate 23 is omitted. In another modification the stop actuating means includes a rocking arm which carries the stop at one end and a roller at the other which is depressed by the passage of an article.

Patent GB-929725-A (GB)
Title: Automatic chain tightening mechanism for infinitely variable cone pulley gears
IPC: F16H9/16
Filed: 1962-04-19
Abstract: 929,725. Expanding wheel gearing; belt gearing; ratchet gearing; linkwork. W. REIMERS. April 19, 1962 [April 19, 1961; March 17, 1962], No. 15272/62. Classes 80 (1), 80 (2) and 80 (3). In an expanding pulley belt or chain gearing, in which both pairs of conical flanges 3, 4 and 5, 6 move relatively axially in opposite directions for a ratio change and may be moved axially in the same direction by a tightening spindle 14 to tighten the belt or chain 7, the spindle 14 is turned by mechanism controlled by a device responsive to the belt tension, operable when the tension decreases and inoperable at other times. In one embodiment, Figs. 1 to 3, spring-pressed shoes 15, 16 cause a slack run of the chain 7 to drive a drum 22 carrying planet pinions 26 engaged by two sun gears 24a, 24b in opposed one-way connection through roller ratchets 25 with a shaft 21, and by a sun gear 24c rigid with a pivot member 11 for the gear adjusting links 8, 9. The gears 24 are of slightly different diameters such that rotation of the drum 22 in either direction produces slow rotation of the shaft 21 in one direction to act through opposite pitch threads to decrease the distance between the pivots 11 and tension the belt. In a second embodiment, Fig. 5, tension sensing levers 17, 18 are connected to a pushrod 50 which, on decrease in chain tension, allows a pawl holder 52 to move into the path of an eccentric strap 51 driven from the gear input shaft 1, and rotate a ratchet-wheel 54 rigid with the threaded shaft 21. In a modification, Fig. 6, the levers 17, 18 are coupled to a spring-loaded lever 61 which forms, in conjunction with a lever 65 pivoted on the gear casing, a snap action switch to engage the reciprocating push-rod 66 with the eccentric 60 only when the chain tension decreases and to disengage the push-rod when the tension is correct. The outer member 67 of a ratchet clutch 68 on the shaft 21 may be held by a positive detent on the push-rod 66 in the inoperative condition. In another embodiment, Fig. 9, sloping surfaces 125 on the levers 17, 18 cause engagement of a pawl 129, driven from the speed adjusting shaft 14, with a ratchet-wheel 122 rigid with the shaft 21. In a modification, the pawl 129 may be driven slowly through skew gears from the driven shaft 2. Where the gear ratio may be also dependent upon the torque transmitted through camming balls 91, Fig. 14, excess freedom in the camming mechanism, due to a slack chain, allows a conical member 92 to engage a corresponding conical member 98 and drive an adjusting sleeve 80 through a double worm reduction gear.
