Title: Multiple stage drag and dynamic turbine downhole motor
Inventor: BARNETCHE-GONZALEZ EDUARDO
IPC: F03B13/02
Filed: 1992-05-08
Abstract: ABSTRACT OF THE DISCLOSURE           A multistage  turbine  is  provided  for  driving  a downhole motor (1), which is driven by the flow of a fluid therethrough.  The turbine comprises a housing (3) and a shaft (5) positioned in the housing, the shaft rotating about the longitudinal axis thereof.  A plurality of turbine stages (9) are mounted on the shaft for rotation therewith, each turbine stage  including a  rim  (15)  coaxial with the  shaft  and a plurality of turbine blades (13) fixed to the rim.  A plurality of flow directing stators (11) are positioned between adjacent turbine stages, each of the stators having a wall portion and diverter portion  (17,  19),  wherein the wall portions  are perpendicular to the axis of the shaft and the diverter portions are at an angle of less than 90° with respect to the axis of the shaft. At least one of the turbine blades and the diverter portions form a seal for preventing the flow from passing therebetween,  such  that  flow  through  a  turbine  stage  is perpendicular to the axis of the shaft in the space between adjacent wall portions and wherein the diverter portions are positioned with respect to said wall means for diverting flow from the turbine stage to an adjacent turbine stage.          The turbine blades are positioned between adjacent stators such that flow between the wall portion of adjacent stators contacts the edges of the turbine blades,  thereby imparting a drag force on the turbine blades and flow through adjacent diverter portions impinges upon the face surface of the turbine blades, thereby imparting a dynamic force on the turbine blades,  whereby  the  turbine  blades  are  rotated  by  the combination of the drag forces and dynamic forces thereon.

Abstract: A shared-buffer-memory-based ATM switching module (1) used with ATM cells having a multiplicity of priorities has a plurality of queues for each output port (O-N), one for each cell priority, and handles buffer overflow in a manner fair to all output ports. It initially allows output-port queues to completely consume the buffer memory (12). Thereafter, when an additional incoming cell (on 7) is received for which there is no room in the buffer memory, the lengths of all of the queues of each output port are individually summed and compared to determine which port has the greatest number of buffered cells. A buffered ATM cell is discarded from the lowest-priority non-empty queue of that port. The incoming cell is then stored in the memory space vacated by the discarded cell. <IMAGE>

Inventor: RUDE EDWARD T
IPC: E05D11/10
Filed: 1991-11-04
Abstract: There is disclosed a hinge assembly that has a pintle (9) and two plates that can rotate about the axis of the pintle. The first plate (17) is irrotatably affixed to the pintle. The second plate is part of a friction element which also includes a band having a plurality of turns helically disposed about the pintle. Between the other end (15) of the band and the second plate there is a spring (13) that tightens the band about the pintle. The band is flexible enough so that it does not grip the pintle without the force of the spring. Frictional force is developed between the band and the pintle that opposes movement of the second plate in a direction that tends to tighten the band about the pintle. Movement of the second plate in the opposite direction tends to loosen the band's grip on the pintle so that very little frictional force is developed.

Title: Arc interrupter apparatus having contact bounce suppressor
Inventor: KAMP EUGENE L
IPC: H01H33/18
Filed: 1992-09-11
Abstract: ABSTRACT OF THE DISCLOSURE An arc spinner interrupter apparatus includes a first electrical contact assembly having a fixed contact and an arcing element.   A second electrical contact assembly includes an arm selectively movable along a path into and out of engagement with the fixed contact.  The arcing element extends beyond the fixed contact in a direction parallel to the path of the arm and is biased toward a position at least partially within the path of movement such that the arm impacts and engages the arcing element during movement toward the fixed contact.  A mass is biased toward a position in  contact  with  the  arcing  element  for  dampening oscillation  of  the  arcing  element  in  a  direction transverse to the path of movement.   When the arm impacts the arcing element the kinetic energy of the arcing element acting in the transverse direction is transferred  from  the  element  to  the  mass  and oscillation of the element is reduced.

Title: High performance bearing pad for thrust bearing
Inventor: HALL DAVID R
IPC: F16C33/26
Filed: 1992-11-20
Abstract: ABSTRACT OF THE INVENTION Cylindrical bearing pads are insertable into bearing pad recesses  formed  in a receiving surface of a bearing pad retainer in a load-carrying structure.  The bearing pads have an insertion end which is fixed into the bearing pad recess by brazing or by interference fitting and a bearing end which projects  from the receiving surface and terminates  in a bearing  face.    The  bearing  face  has  a  periphery  which encircles  the  bearing  face  and  an  indentation  having  a perimeter formed centrally in the bearing face.  An annular flattened area encircles the indentation forming an effective bearing contact area between an outer border of the flattened area  and  the  perimeter  of  the  indentation.    When  the indentation is filled with drilling fluid,  lubrication is provided to an opposed bearing face of an opposing bearing pad.  The indentation can be filled with drilling fluid or some other material with a higher heat storage capacity than polycrystalline diamond to provide temperature modulation for storing heat produced at the bearing face.  When filled with a material, the indentation also serves to dissipate heat to reducing the length of a path of heat when the heat is conducted to cooler areas of the bearing face.   Alternate embodiments  include bearing  faces with single  or plural indentations of various shapes. G:\pat\117922.pat

Title: Miniature fiberoptic bend device and method
Inventor: STOWE DAVID W
IPC: G02B6/26
Filed: 1991-06-17
Abstract: Bends in optical fibers (14) can be miniaturized by reducing the diameter of a section (18) of the fiber in the region where bending (20) is desired. In one aspect of the invention radii of curvature less than 100 microns and very low optical power loss are achieved. A fiber with greatly reduced diameter (Fig. 1d, Section-b-b) may also be twisted about its longi-tudinal axis to a greater degree than a comparable length of larger diameter fiber. In another aspect of the invention, reduc-ing the cross-sectional area of fiber is not required. Bent sections of the fiber are thermally annealed forming stress free bends of minimum bend radius for long term applications. Any optical fiber can be processed by redrawing and/or chemical means to allow such bending or twisting. Bend or twist tolerant regions and annealed bends may be packaged separately or built integrally into a wide range of fiber optic components; sensors; networks, or systems with significant space savings, added performance features and mechanical flexibility.

Title: Push rod retention shelf for an engine
Inventor: BRAKER BRENT L
IPC: F01L1/46
Filed: 1991-08-30
Abstract: The design and construction of past pushrod retainers have required complex components, sliding relationships and additional assembly time and expense. The present invention overcomes these problems by using a retention shelf (144) attached to a cylinder block (14). Thus, the components are simple to install, inexpensive to manufacture and do not increase assembly time since there is no adjustment necessary when using the device. The present retention shelf assemblies (142) provide a device which prevents extensive damage to the engine (12) caused by a large separation between the cupped end (96) of the pushrod (94) and the first end (50) of the rocker arm (46) which allows the pushrod (94) to fall into other components, resulting in malfunction of the engine (12). The device is preassembled to the cylinder block (14) and requires no additional assembly time or alignment when assembling the engine (12). The device is inexpensive to manufacture and prevents the pushrod (94) from causing damage to the engine (12) should the first end (50) of the rocker arm (46) not be moved to the second operating position (84) causing the pushrod (94) to become free or disconnected.
