Abstract: On réalise une anastomose terminolatérale entre un premier vaisseau (27) et un deuxième vaisseau (51) au moyen d'un instrument d'anastomose comprenant un tube (20) dans lequel on introduit le premier vaisseau (27) que l'on retourne à l'extrémité dudit tube (20), afin de former un col (28), un raccord anastomotique élastique (30) pourvu de pointes (32) dirigées vers l'extérieur ayant été préalablement placé sous incurvation élastique dans un évidement circulaire (22). On introduit le tube (20) dans une incision pratiquée au préalable dans le deuxième vaisseau (51), tandis qu'un élément de guidage (35) permet le contact de la région de paroi (53) située autour de l'incision avec le col retourné (28). On utilise ensuite un éjecteur (23) afin de libérer le raccord (30) de l'évidement (22), ce qui provoque la dilatation rapide dudit raccord, de telle manière que les pointes (32) pénètrent dans le col (28) et dans la région de paroi (53). On enlève ensuite le tube (20) et l'éjecteur (23), ainsi que l'élément de guidage (35) qu'on a laissé s'affaisser préalablement, d'une façon non représentée par la figure, afin de pouvoir le retirer par le premier vaisseau (27).

Abstract: The present invention provides a concrete form comprising a housing having a foot portion and a leg portion. The leg portion of the housing has a top end and a bottom end. The leg portion of the housing consists of four equi-spaced identical semi-conical wall segments and four concave wall segments joining adjacent semi-conical wall segments to provide a generally truncated conical configuration with a rounded cross or four leaf clover horizontal cross section. The top and bottom end of the leg portion is open.          The foot portion is an inverted dish shape. The dish shaped foot portion has an annular side wall and a top wall. The bottom end of the leg portion is coaxially connected to the top wall of the dish shaped foot portion. An opening is provided in the top wall of the dish shaped foot portion the same size and shape as the internal cross-section of the bottom end of the leg portion. The concrete form of the present invention because of its unique construction provides numerous advantages over conventional fiber tubes. It is easier to dig a hole into which the form can be inserted; the present invention will take about one third the volume of concrete that a similar sized fiber tube and due to its tapered construction, the concrete forms of the present invention will resist upward frost movement.

Title: Acoustic echo elimination in a digital mobile communications system
Inventor: SUVANEN JYRI
IPC: H04B7/26
Filed: 1996-06-07
Granted: 2006-04-11
Abstract: The invention relates to a method and arrangement for eliminating acoustic echo generated in a mobile station in a mobile communications system. According to the invention, an echo suppressor is placed on the side of the mobile network for eliminating the acoustic residual echo of the echo canceller of the mobile station. The echo suppressor comprises a downlink voice activity detector (35) because it is possible that the downlink speech returns from the mobile station as an acoustic echo superimposed to the uplink signal. When the detector (35) detects the downlink speech, a selector (303) disconnects the uplink signal from the speech decoder (38) and supplies in its place noise from the generator (302). The spectral characteristics and intensity of the comfort noise are similar to those of the background noise do the operating environment of the mobile station at each moment. Generation of the noise is started after a predetermined delay from detecting the voice activity, and terminated after a predetermined delay from the end of the voice activity.

Abstract: A method of and apparatus for spectrophotometrically analysing  a tablet  by  NIR  transmission  measurements includes a tablet holder 1 having a recess 5 within which a tablet 20 is located.     A probe 40 is applied to the tablet 20 to direct an NIR beam 45 to and through the tablet for sensing at a detector 32 from which measurements characteristics of the tablet are analysed.   The recess 5 accommodates  the  tablet  20  as  a  close,   possibly complementary fit.   The tablet is clamped in the recess 5 by a spring loaded rod 8 to ensure that the tablet is located and retained at a predetermined position in the recess  5  relative to an aperture 7  through which the transmitted  beam  is  directed  to  the  detector  32. Preferably the tablet 20 is subjected to clamping forces applied  by  two  spring  loaded  clamping  rods  disposed substantially perpendicularly relative to each other in the tablet holder.     The effect of clamping the tablet in the tablet holder permits reproducible analysis measurements to be achieved from which may be determined the acceptability or  otherwise  of  the  characteristics  of  tablets  as manufactured commercially.    The invention also provides for the structure of a tablet holder.

Abstract: A scroll compressor includes a scroll set in which fluids at various operating pressures impart a plurality of forces on the scroll set orbiting and fixed scroll members. An axial biasing force is applied against the orbiting scroll member urging same toward the fixed scroll member. Fluid at discharge pressure exerts an axial force at a first area of the back surface of the orbiting scroll member which urges the orbiting scroll member toward the fixed scroll member to maintain axial compliance therebetween and to prevent leakage of compressed refrigerant fluid during compressor operation. An axial anti-biasing force is applied between the orbiting and fixed scroll members to urge them apart. An annular chamber provided between the end plates of the orbiting and fixed scroll members forms a cavity that is in communication with fluid contained in pockets of compression in the scroll set. The fluid in the pockets of compression is at a pressure intermediate discharge and suction pressures. A passage provided in the scroll set communicates the intermediate pressure fluid from the pockets of compression to the intermediate pressure cavity. The intermediate pressure fluid acts upon the opposing face surfaces of the orbiting and fixed scroll members urging them apart. In this manner, an unbiasing force is exerted between the scroll members to offset excessive axial biasing forces which may act upon the orbiting scroll member, thereby preventing excessive wear and power consumption and providing enhanced operating efficiency. The intermediate force effectively acts as a cushion to lessen the biasing force at the higher end of the operating range.

Abstract: A method is disclosed for borehole compensation of measurements of earth formations penetrated by a borehole including differential time (.DELTA.t) measurements obtained from a borehole tool in the formation. The borehole tool includes at least one transmitter and a plurality of receivers spaced apart from each transmitter. Each transmitter generates a waveform, and the receivers are responsive to the waveform. A receiver array .DELTA.t measurement is generated for a depth interval spanned by the receivers by cross-correlating receiver array waveforms relevant to the spanned depth interval. A synthesized transmitter array .DELTA.t measurement corresponding to the spanned depth interval is generated by cross- correlating selected transmitter array waveforms. The transmitter array waveforms are selected corresponding to the spanned depth interval by identifying the receiver arrays whose transmitter locations fall within the spanned depth interval and identifying a set of waveforms from the identified receiver arrays to obtain the transmitter array waveforms. The receiver array .DELTA.t measurement is averaged with the transmitter array .DELTA.t measurement to obtain a borehole compensated .DELTA.t measurement corresponding to each transmitter. When the borehole tool includes more than one transmitter, all the borehole compensated .DELTA.t measurements corresponding to each transmitter are averaged to obtain a comprehensive borehole compensated .DELTA.t measurement.
