| 20120006735 | Separating Screens - A separating screen has a rectangular body ( | 01-12-2012 |
| 20110284455 | Sifting Screen - The invention relates to a screen frame adapted for use in a shaker and to which woven wire mesh is to be attached, comprising an outer perimeter and a plurality of plastics ribs extending between opposing regions of the perimeter, the frame being arranged such that, when fitted in a shaker to which it is adapted for, a portion of the opposing regions is clamped in place and a portion of the opposing regions is not clamped with the number of plastics ribs per unit length for the clamped portion greater than the number of plastics ribs per unit length for the unclamped portion, and to a shaker comprising at least one such screen frame. | 11-24-2011 |
| 20110266214 | Improved Sifting Screen - The invention relates to a screen frame adapted for use in a shaker to separate solids from a liquid/solid mixture and to which woven wire mesh is to be attached, comprising an outer perimeter and a plurality of plastics ribs extending between opposing regions of the perimeter, the plastics ribs together forming an upper face and a lower face, wherein the frame further comprises at least one metal rib extending between opposing regions of the perimeter and extending from the upper face to the lower face, and to a shaker comprising at least one such screen frame. | 11-03-2011 |
| 20110259814 | SIFTING SCREEN - There is provided a screen frame adapted for use in a shaker to separate solids from liquid/solid mixture and to which woven wire mesh is to be attached, comprising a plurality of intersecting elongate members ( | 10-27-2011 |
| 20110215047 | LOCATING FEATURE FOR SCREEN - A vibratory separator screen assembly, the screen assembly including a frame having a top surface and a bottom surface having a tapered recess configured to receive a locating element disposed on the vibratory separator. The system also includes a screen element | 09-08-2011 |
| 20110155653 | Sifting Screen - The invention relates to a screen frame adapted for use in a shaker to separate solids from a liquid/solid mixture and to which woven wire mesh is to be attached, comprising an outer perimeter and a plurality of ribs extending between opposing regions of the perimeter, the ribs defining an upper horizontal face to which a screen is to be attached, wherein at least one rib extends downwardly from the upper face at an angle off set to vertical, and to a shaker comprising at least one such screen frame. | 06-30-2011 |
| 20110139688 | PERIPHERAL SEALING SYSTEM FOR PRE-TENSIONED SCREENS - A method of forming a shaker screen includes forming a frame, and attaching a first sealing element to at least one side of an outer perimeter of the frame, wherein the attaching comprises aligning a first mating surface of the frame to a second mating surface of the first sealing element, and wherein the first mating surface of the frame includes an extension, and the second mating surface of the first sealing element includes a groove configured to align with the extension. A system of sealing shaker screens includes a first screen and a second screen disposed adjacent the first screen, wherein a first sealing element of a first frame and a portion of the second screen interact to provide a seal between the first screen and the second screen. | 06-16-2011 |
| 20100307962 | PREFERENTIAL BOW ON COMPOSITE SCREENS - Abstract: A shaker screen for attachment to a bed of a shaker includes a screen frame having at least one mesh screen attached to the top side of the screen frame, wherein the screen frame is preferentially bowed prior to attaching the mesh screen to the screen frame. | 12-09-2010 |
| 20100270215 | VIBRATORY SEPARATOR SCREEN ATTACHMENT - A vibratory separator including a screen frame and a screen attachment. The screen attachment including at least one vertically disposed latch on the screen frame, at least one vertically disposed catch on the screen frame, and at least one bearing surface proximate the at least one vertically disposed catch. Additionally, a method of securing adjacent screens including inserting a vertically disposed latch of a first screen into a catch of a second screen, wherein the inserting includes contacting the latch of the first screen with a bearing surface of the second screen adjacent the catch of the second screen. The method further includes forming a planar alignment of the first screen to the second screen. | 10-28-2010 |
| 20100219110 | Sifting Screens - A frame over which woven wire mesh is to be stretched and secured to form a sieving screen and which can be used to screen solids from drilling mud recovered from down-hole when drilling for oil or gas. The frame is a rectilinear moulded plastics frame having edge regions by which it is secured in place in a shaker. Within the frame is a plurality of rectilinear windows formed by an orthogonal array of intersecting ribs also of moulded plastics material. Some of the ribs are internally reinforced by rigid metal members which extend orthogonally between hollow box-section members which define a sub-frame for reinforcing the four edge regions of the frame. The orthogonal members are secured at their ends to the sub-frame. The ends of the sub-frame members are joined at the four corners of the sub-frame. In this way not are only the edge regions of the frame reinforced internally but so also are some of the orthogonally intersecting ribs, so as thereby to produce a rigid frame for the screen. The internal reinforcement for those ribs which are to be reinforced may comprise hollow box-section metal members which may be of similar cross section to that of the sub-frame members, or the internal reinforcement for those ribs which are to be reinforced comprises metal I-beam cross section members, which typically have the same height as the height of the box-section members forming the sub frame. | 09-02-2010 |
