Title: Sonic well logging tool for radially scanning cementing conditions in cased wells
Inventor: TELLO LUCIO N
IPC: E21B47/00
Filed: 1995-09-08
Granted: 2000-05-23
Abstract: A  sonic  well  logging  tool  radially  determines circumferential placement of cement longitudinally along exterior surfaces of a well casing. The sonic well logging tool includes a frequency shifting modulator for shifting the  frequency of  high  frequency  electrical  signals to provide analog data signals having substantially  lower frequencies.  The analog data signals have waveform shapes which directly correspond to time stretching the shapes of waveforms  for  the  high  frequency  electrical  signals representing  high  frequency  sonic  signals.    The  high frequency  electrical  signals  are  frequency shifted to substantially lower frequencies which can be transmitted uphole over a wireline.   The  sonic well  logging tool further includes high frequency sonic transducers which do not extend in a particular direction for substantially more than one quarter of a sonic waveform length of the high frequency  sonic  signals  travelling  in  the  particular direction within a sector of casing.

Abstract: A shield that is normally positioned or wrapped around a boiler tube when such tube is exposed to extreme operating conditions.  This shield consists of an elongated strip of thin material that is formed as a helix.  This strip also incorporates a means for spacing this strip from the tube so as to create a gap between the tube and the shield.  Generally the shield is secured  to  the  tube  by  spot  or  button  welding  only  the longitudinal end regions of the strip to the tube.   By thus wrapping and securing one or more such shields to the tube, the tube  is  protected while  still  permitting  both  it  and  the shield(s) to expand and contract as needed.

Abstract: Planning and toy assemblies of the invention comprise element receiving and storage members and a plurality of elements adherable by permanent magnet attraction to their receiving surfaces, the assembly also usually comprising a folder in which they are stored and carried. Each member comprises a thin sheet of magnetizable metal with a surface sheet mounted thereover. The receiving member surface carries a planning grid or picture, while the storage members have depictions on their exposed surfaces of the elements that are placed thereon. Each element is a piece punched from permanently magnetized sheet material of sufficient magnetic field strength to adhere to the metal sheets, even through a thin non-magnetic layer, and also carries a depiction of what it represents. Each element depiction has a respective visual orientation, while the sheet material has a respective magnetic orientation, and preferably while one plurality of the elements have their visual and magnetic orientations in a first angular relation, another plurality have their orientations in a different angular relation, so that elements of the two pluralities can overly one another without interaction of the magnetic fields that might otherwise cause unwanted relative movement between the overlying elements. A further plurality may have their orientations in an angular relation different from that of the other two pluralities for the same purpose. The two or three pluralities of elements may be formed by stamping from a single sheet of the material, and thereafter are mounted on the storage members with the same visual orientation.

Abstract: In a microscopic screening apparatus a calibration slide (28) is mounted on a stage (18) of a microscope (36), and a microscope positioning system is calibrated by reading and storing (1008) in memory the location of at least one fiducial marking that is on the calibration slide (28) using a microscope-dependent coordinate system. Next, a sample containing slide is mounted against the stage (18) of the microscope (36). The location of at least one feature on the sample containing slide is then transformed (2006) into a microscope-independent coordinate system, and is stored (2008) in a memory. Using a second microscope (36), a second calibration slide (28) is mounted against the stage (18) of the second microscope (36), and the second (36) microscope is calibrated using (36) a second microscope-dependent coordinate system, based on the second microscope (36). Next, the sample containing slide is mounted against the second stage (18). The stored feature location is read (3004) from the memory, and transformed (3006) from the microscope-independent coordinate system to the second microscope-dependent coordinate system. The transformed feature location in the second microscope-dependent coordinate system is utilized to relocate (3008) the feature on the sample containing slide.

Title: Synchronization of a stereoscopic video sequence
Inventor: CHEN XUEMIN
IPC: H04N7/50
Filed: 1997-10-20
Granted: 2004-07-13
Abstract: In a stereoscopic video transmission system, video pictures of lower and enhancement layers are transmitted in a particular order such that the number of pictures which must be temporarily stored prior to presentation is minimized. Furthermore, a decode time stamp (DTS) and presentation time stamp (PTS) for each picture can be determined to provide synchronization between the lower layer and enhancement layer pictures. Decoding may occur either sequentially or in parallel. In particular, a method is presented where the enhancement layer includes disparity-predicted pictures which are predicted using corresponding lower layer pictures. The video pictures are ordered such that the disparity-predicted enhancement layer pictures are transmitted after the corresponding respective lower layer pictures. The scheme is illustrated with a number of different specific examples.
