摘要： 1,123,442. Filter. RICE BARTON CORP. 1 Feb., 1966 [2 Feb., 1965], No. 4440/66. Heading B1D. Filtration apparatus comprises a disc press 12 which includes a pair of discs 44 mounted on axes 54, 56 which are inclined at an angle to each other and which lie in a common horizontal plane and a housing 42 which cooperates with each of the discs 44 around at least part of the outer opposed peripheries in labyrinth seals 66, the discs comprising passages 48 for the removal of filtered liquid and presenting mutually opposed frustoconical screened disc surfaces 62 defining a pressing zone which varies in thickness from a section of maximum thickness communicating with an input zone 40 to a section of minimum thickness communicating with an output zone 86. Wood fibre slurry is fed to the input zone 40 of the disc press 12 by a screw extrusion press 10, which incorporates precision-ground stainless steel bristles 24 (Fig. 5 not shown) secured along the edge of screw 22, and a lump breaker 34 which may be selectively moved to control the operating pressure within steel screen 60. Screw 23 screen 26 and casing 28 are all in joined semicylindrical portions. A standpipe (39) (Fig. 6 not shown) may be used to control the liquid head. Holes 48 in the discs 44 communicate with concentric grooves 50 and radial grooves 52. A doctor 70, the sides of which are spaced closely to screens 62, provides water lubrication holes 71 and a knot removal chamber 74 in which knots carried by screens 62 into chamber 74 are both rubbed from the screens and upwardly removed by auger 76. Material leaving output zone 86 is broken up by shredder 90 which comprises teeth 92 carried by chains running on sprockets 94. The rate of rotation of discs 44 is varied by pressure sensor 85 mounted in input zone 40 or the output zone of the screw extrusion press, 10.

摘要： 1,018,367. Removing water &c. from felts. RICE BARTON CORPORATION. Oct. 6,1964 [Oct. 14,1963], No. 40772/64. Heading D2A. [Also in Division F4] Foreign substances-for example water, paper fibres, and particles-are removed from dewatering and transporting felts in paper-making and other machines by passing the felt around a curved surface of sufficiently small radius that the foreign substances are flung out by centrifugal force, air being introduced to the innerside of the felt under sufficient pressure to reduce friction and to fill voids created therein. In one example felt 73 passes over supports 64, 65, air under pressure being supplied from tibe 58 through holes 76. In other examples the felt passes over a fixed perforated tube having a perforated cover of polytetrafluoroethylene, over a rotating perforated roll, over a plurality of rotating rolls mounted on a shaft, or over a perforated oval shape tube. Air may be supplied under sufficient pressure to lift the felt off the curved surface. A shower tube may be placed upstream of the curved surface and a felt conditioning shower tube downstream thereof. The felt may pass around a series of curved surfaces.

摘要： 863,292. Flow-boxes of paper-making machines. RICE BARTON CORPORATION. Jan. 14, 1959 [Jan. 23, 1958 (2)], No. 1420/59. Class 96. A flow-box of a Fourdrinier paper-making, machine has perforated flow-evener rolls 18, 20, 22 and provision at 24, 82, 84, 86 for foam removal, and a slice outlet formed by an apron 26 with a lower lip 27 and an arcuate slice-plate 28 which slides against the forward edge of a thin flexible blade 30 between which blade 30 and plate 28 in an air-loaded sealing-tube 118 which lies adjacent to a Z-section strip 114 securing the rear edge of the blade 30, the tube 118 preventing leakage of pulp from the space 124. A shaft 34 carries the slice-plate assembly and is turned about its own axis by rotating a screw 67 to actuate fore-and-aft jack-screws 44 to give fore-and-aft movement of the slice-plate 28. Vertical movement of the slice lip is effected by rotating a shaft 68 to actuate up-and-down jack screws 64 to rotate an upper shaft 58 about its own axis to raise or lower local, slicelip adjustment rods 54. The roll 12 may be substituted by a suction breast roll. A modified form of both fore-and-aft and up-and-down adjustment of the slice lip is also described.

摘要： 1,000,934. Web coating apparatus. RICE BARTON CORPORATION. May 23, 1963 [May 28, 1962], No. 20680/63. Heading D1L. A trailing blade type coater having a backing roll 10 over which a travelling web 16 to be coated is drawn in a downward direction and a pond and doctor blade assembly including a pond enclosure having an open face closed by the web, and a doctor blade forming a bottom closure against the web, is characterised by movable supports on which the pond enclosure is movable for adjustment toward and away from the travelling web and a system of relatively shiftable overlapping main and auxiliary dyke members forming a liquid light expandable and collapsible closure between the rear face of the pond enclosure and the web, at each end of the pond. As shown the doctor black and pond assembly comprises a tubular support member 17, a bar 18 bolted thereto and shaped to provide a pond for the coating material, a lower movable jaw 22 which supports doctor blade 23 and a dykes assembly 24, 25 at each end. Each dyke assembly consists of a dyke 24 fitted to and in fixed relation to the internal face of the pond to be movable adjusted therewith and an auxiliary dyke 25 which is held in a relatively stationary position adjacent the backing roll and web the two dyke parts having sealing means there between and being capable of relative movement. The tubular member 17 has, secured to each end, end plate members 26 which are pivotally mounted on elements 28 at 32, the pivot 32 being substantially in alignment with the edge of the doctor blade so that the entire assembly can be rocked about this edge. The elements 28 are pivotally supported by pins 38 on normally stationary brackets 42 pivotally mounted on shaft 12 of roll 10 such that movement of links 28 about pins 38 will have the effect of moving the pond and doctor blade assembly in an in and out direction with relation to the backing roll 10 and web 16. Rotational movement of brackets 42 has the effect of raising or lowering and thereby adjusting vertically, the position of the pond and doctor blade assembly. The position of brackets 42 is determined by links 48, 52 and rock shaft 56 operated by a motor and brake unit 58. Rocking of the assembly about centers 32 is controlled by a pair of pneumatic cylinders 60 and associated pistons 62 and the in and out adjustment is controlled by a pair of pneumatic cylinders 68 and associated pistons 72. The dyke assemblies for closing the end of the pond have air pressure sealing means at their peripheries and the two positions 24 and 25 are in sliding contact with each other by means of bolt and elongated slot connections. Further the dyke assemblies are adjustable in position by telescoping connections 100, 102; 86, 88. The doctor blade 23 is mounted in a holder 110 which in turn is mounted in the slotted upper surface of slide bar 112 which is supported for backward and forward sliding movement between upper jaw 20 and lower jaw 22. Towards its outer edge blade 23 is supported by edge plate 114 there being a loose fit between the jaw 20 and plate 114 so that the blade 23 can bend downwardly under the pressure of fluid in the pond. The lowe jaw 22 is mounted on a series of yokes 116 which are pivotally mounted on shaft 118 and has rearward extensions 120 which engage an inflated tube 122 resting against the underside of tubular member 17 so that the weight of the lower jaw is carried directly by the member 17 and thus does not tend to strain or warp the blade 23. Forward and backward adjustment of the blade 23 can be effected by means of screw threaded rods 124, sleeves 126 and nuts 128. A fine adjustment may be effected by knobs 134. In a second embodiment the entire dyke assembly is mounted on a bracket which is supported for adjustment longitudinally on a guide bar secured to the bar 18, and comprises two spaced parallel plate members with a movable auxiliary member there between.
