IPC: B30B11/12
Filed: 1968-04-23
Abstract: 1,215,977. Roller and ring extruder. H. LIST. 23 April, 1968, No. 19190/68. Heading B5A. Apparatus for moulding powdery or pastelike materials into a granulate, comprises a pair of oppositely rotating rollers 41, 42 respectively located within and outside the circumference of a rotating ring member 40 and defining a nip whereat the material is compacted into apertures extending through the ring member 40. In the Fig. 5 embodiment, the material is pressed by a smooth roller 42 into apertures extending through the ring member 40, which a roller 41 contacts only at the edges thereof and is provided therebetween with a circumferentially extending recess whereby the material extrudes as strands 46 on the interior of the ring member 40. At the nip 47 of a further similar roller pair 43, 44 the strands 46 are similarly extruded to the exterior of the ring member 40 from whence they are cut by a knife 48. Further pairs of rollers may be provided. In the Fig. 3 embodiment, not shown, a single similar nip (20, 21) is provided whereby the strands (27) are cut by a knife (28) in the interior of the ring member, and a stationary shoe (30) may be provided in the interior of the ring member (23), at the entrance to the nip, which acts to prevent the premature passage through the cavities of powdery materials and has a trough at the trailing end thereof which collects waste material scraped from the interior of the ring member (4) by the trailing contacting edge of the shoe (30). In the Fig. 1 embodiment (not shown), both nip rollers (1, 2) co-operate to pass material into the ring member apertures (5) from which the granulate may be ejected outwardly by compressed air nozzles (8) located within the ring member (4); alternatively, for larger granulate, mechanical ejection devices may be driven by teeth thereon engaging perforations at the end of the ring member (4) or, with a flexible ring member (4), the ejection may be performed by the deflection thereof by rollers or by a jolting action. The ring member (4) is driven by frictional engagement with the nip rollers or by toothed engagement with the interior nip roller (1). Where it is necessary to maintain the material in a plasticized condition, the nip rollers are heated and the granulate solidified by cooling air or gas blown on to the forming member which may be reheated by hot air or inductive means prior to the roller nip. One roller member may also be rotated at a higher velocity or tangentially or radially oscillated. One of the rollers may also be provided with teeth and the forming member may be provided, either externally or internally, with counter teeth at the base whereof the apertures are located.

Filed: 1960-06-01
Abstract: 931,024. Purifying water. SUN OIL CO. June 1, 1960, No. 19442/60. Class 46. In a process in which fresh water is taken from a suitable source of supply through line 1 and is fed to boilers or other generating means 2 and 4 and condensate from such heating and power units which has come in contact with contaminants such as lubricating oil is taken off through line 6 and mixed with other plant water streams, eventually flowing into oil separator 17 and being collected in basin 20, the water from basin 20 is passed to the cooling towers 23 via return line 27 as the temperature in the line is also ideal for bacterial growth and the high degree of aeration obtained in the towers is exceedingly favourable for bacterial oxidation. In case the water from impounding basin 20 is insufficient to furnish make-up water for the cooling towers, fresh water may be introduced through line 24 in an amount sufficient for that purpose. The water from the cooling towers is circulated to coolers and condensers 25 through line 26 and is returned to cooling towers 23 through line 27. Circulation of the water is continued until an equilibrium amount of dissolved solids is built up in the water after which a regulated amount of cooling tower blowdown water will be removed from cooling towers 23 through line 28, a portion thereof being deflected through line 29 to crude oil desalter 30. Water from desalter 30, which will contain only a small amount of entrained oil and water soluble phenols is taken through line 31 and mixed with the balance of the cooling tower blowdown water, and then passed to oil separator 32, oil being withdrawn therefrom through line 33 and effluent water for discharge to the sewer through line 34. U.S.A. Specification 2,899,385 is referred to.

Title: Molten adhesive dispensing device
IPC: B05C17/005
Filed: 1976-04-01
Abstract: 1517822 Heating adhesive in applicator device NORDSON CORP 1 April 1976 [7 April 1975] 19598/77 Divided out of 1517821 Heading B2L Solid adhesive feedstock is melted at a reservoir distant from the use location and maintained at a relatively reduced temperature level which will not degrade the feedstock over an extended period; a heat exchanger is provided in the discharge head of the dispensing device at the use location and molten feedstock is passed from said reservoir to said discharge head, where prior to application to a substrate, it is heated by the heat exchanger to a relatively higher use temperature at which the adhesive would degrade were it to be maintained at the use temperature for an extended period. Molten adhesive is fed at reduced temperature from a distant reservoir via 71 to gun 10. Various nuts and washers serve to constitute a swivel connection 72 through which adhesive passes before being fed to a spiral channel 114 between a threaded core 106 and threads on the inner bore 97b of a heat exchanger block 14 heated by cartridge heaters placed therein (Fig. 7, not shown). Here the adhesive is heated to said use temperature, monitored by thermostat 141, and then passes via 110 into bore 22, whence it is discharged via nozzle 23, by pulling trigger 49 such that valve 34 retracts against the pressure of spring 50. An alternative type of heat exchanger core is a fluted cylinder which slip-fits into bore 97b, the adhesive in this case following a plural linear path along the flutes (Figs. 4 and 7 not shown).

Title: Improvements in the manufacture of yeast
IPC: C12N1/18
Filed: 1919-08-11
Abstract: 153,667. Aktieselskabet Dansk Gaerings Industri, and Sak, S. Aug. 11, 1919. Yeast; alcohol.-In fermenting to produce yeast, especially by the aeration process, additions are made to the fermenting mixture of wort or mash of higher concentration than that in which the fermentation is commenced in order to maintain the concentration of the nutrient substances. The alcohol in the fermented mixture mav be recovered, and its amount may be varied by varying the temperature, aeration, &c. so that more or less is assimilated by the yeast. The liquid to be fermented may be sown with an amount of yeast up to 60 per cent of the material used in making the mash. A mash prepared in the usual manner from maize, barley, or barley malt and malt-culms, is filtered and the residues washed. The weak washing waters are sown with yeast, and during the fermentation additions are made at intervals of the stronger washing-water and of the filtered wort, the liquid being aerated by passage of air which is reduced in amount in the later stages of the fermentation. Additions of ammonium sulphate, ammonia solution, or nutritive salts may be added at intervals. Specification 3196/04 is referred to.

Title: A machine for offset multicolour printing on containers or the like having the shapes of truncated cones
IPC: B41F17/28
Filed: 1945-08-02
Abstract: 613,023. Printing on cones. WAGNER, J. Aug. 2, 1945, No. 19905. [Class 100(ii)] A machine for printing on containers &c. shaped like a truncated cone is constructed so as to be capable of dealing with containers which vary in diameter and in inclination. In all cases the truncated cones are mounted on chucks 19 mounted to rotate about an axis a, b and the vertex F of the cone is arranged to be at the junction of the axis a, b and plane of the printing- surface 7. The chucks 19 are mounted on four arms 10, 11, 12, 13 of an intermittently rotatable device 9, and the chucks are adjustably connected to arcuate slots 20 having the vertex point F as centre, so as to adapt the printing operation to cones of different inclination. Also for dealing with cones of different diameters the device 9 and associated parts are adjustable longitudinally in the printing plane by arranging its base 14 to be capable of sliding along bars 15, the driving means for the device 9 being splined to its driving shaft 16. The cones can be fed and delivered automatically to the chucks when in the position of rest, and during this interval the printing-surface 7 receives its impression and moves to the position II so as to enable the cone to be printed by being rolled over the surface 7. As shown the printing-surface 7 is an offset surface which receives a three-colour impression from rollers 4, 5, 6, as is passes to the printing position. When the printing has been effected the surface 7 is returned to its starting position without coacting with the rollers 4, 5, 6. As shown in Fig. 6, the offset surface 7 is surrounded by a marginal portion 23 outside of the printing area, and rotation of the cones is started while engaging the marginal portions, and so the cone is in motion as it contacts the offset impression. Adjustment of the position of the chucks 19 may be obtained by using arms radially adjustable in length, or by employing a series of arms of sizes varying by constant amounts. The rotating device is pressed towards the printing surface.
