Abstract: A valve arrangement contains a housing (2) and a shut-off element (8) with which a shaft (10) is rotatably coupled, the passage of the shaft through the housing (2) being sealed by means of sealing elements (32). The valve arrangement is to be improved to the effect that, with little constructive expense, the leakage rate can be minimized and strict safety requirements can be satisfied, the valve arrangement being provided in its interior with a lining (20, 21). It is proposed that, as an option to the first sealing element (32), which is disposed in an annular space between the shaft (10) and the housing (2), a second sealing element (42) is disposed at least partially within a ring (3) joined to the housing (2). The lining (20) of the housing (2) reaches at least as far as the first sealing element (32) which is directly in contact with the lining (20), the first sealing element (32), and if necessary the second element, being compressible by means of a bushing (48) movable in the direction of the axis of rotation (14) of the shaft (10).

Granted: 2000-11-21
Abstract: A color-sorting machine for granular materials (1) optically detects raw material grains (G) falling along a substantially fixed path (A) and sorts out no-good grains by color.  An optical detection unit (21; 230) to this end comprises a condenser lens (9; 90), a plurality of optical filters (10a, 10b; 100a, 100b, 100c), and a plurality of light-receiving sensors (12A, 13B; 120a, 120b, 120c) corresponding to the filters and can detect a plurality of wavelengths.  The light-receiving sensors (12A, 13B; 120a, 120b, 120c) lie side by side on the same plane, are formed in a unit body, require no positioning adjustment among the light-receiving sensors, and make it possible to reduce the size of the light detection system.  A prism (11; 110) is provided between the condenser lens (9; 90) and the light-receiving sensors.  The prism has light path diffraction surfaces (11a, 11b; 110a, 110b, 110c) of the same number as the light-receiving sensors, so that the light-receiving sensors receive light of the same point of view and can perform color sorting.  Detected light partition plates (15; 150a, 150b) are provided between adjacent light path diffraction surfaces of the prism and between the corresponding adjacent light-receiving sensors to improve the precision of optical detection.

Title: Face seal having strain induced face geometry
Inventor: PEARCE DAVID E
IPC: F16J15/34
Filed: 1998-11-23
Granted: 2007-05-15
Abstract: The present invention provides a mechanical seal for rotary rock bits with a uniquely formed hydrodynamic wave geometry on the sealing faces. The faces are first manufactured flat and smooth, then upon assembly are elastically deformed into a hydrodynamic geometry by the energizing system. One or both of the mechanical sealing faces are lapped flat to less than about six helium light bands and polished to a minimum of about 5 micro-inch RA surface finish across the entire width of the sealing faces. After the smooth flat sealing surface is formed, the mechanical seal face elastically deforms into a hydrodynamic wave geometry. The typical deformation has a magnitude greater than about three helium light bands more than the original surface. The deformed surface maintains its finish of less than about five micro-inches RA. The region of the sealing surface at the outer periphery of the seal does not have a wave geometry. Rather the portion of the seal face at the periphery is flat and parallel to its mating seal ring to exclude abrasives and eliminate lubricant leakage.

Abstract: The invention relates to circulating subs for use in wellbores, particularly but not exclusively to circulating subs used during downhole drilling operations. The apparatus of the present invention is characterised by controlling means for controlling the movement of a sleeve between first (closed) and second (open) positions; the controlling means comprising: a control member (24) slidably mounted in a body (4) and moveable by fluid pressure in the body (4) in a first axial direction relative to the body (4); a spring (38) biasing the control member (24) in an opposite axial direction of the body (4); a pin (48) secured to one of the body (4) and the control member (24);  and a control groove (32) in which a portion of the pin (48) is received formed in the other of the body (4) and the control member (24), the central groove (32) being shaped to limit axial displacement of the control member (24) in response to pressure variations in the body (4) such that only after a predetermined number of movements of the control member (24) to a first limit position is the control member (24) able to move to a second limit position to displace the sleeve (52) into the second position of the sleeve (52). The present apparatus thereby has the advantage over the prior art of being reliable and convenient to use, and compatible with the use of wireline or coil tubing tools. The apparatus may also be reset many times whilst remaining in a downhole position and is therefore less time consuming and less expensive to use than the prior art.
