Abstract: A cuvette for holding a liquid to be examined optically has front, back, and side walls defining a rectangular cross section and a Y-shaped structure at the bottom thereof for holding the liquid. The Y-shaped structure extends between transparent front and back walls with an upper funnel mouth extending to the side walls, and a liquid holding portion formed of inner walls spaced between the side walls, and extending down to a rounded, tub-shaped bottom. The front walls are transparent and serve also to form the front and back of the liquid holding portion. The bottom preferably has a frustroconic surface to minimize the amount of liquid required for examination and to facilitate mixing of liquids added to the cuvette. The side walls extend below the tub-shaped bottom, and are joined to the front and back wall midway up the liquid holding portion by means of a rib, so that light is not scattered by the side walls and optical inhomogeneities are prevented.

Title: Well packing system
Inventor: DRNEVICH RAYMOND F
IPC: E21B35/00
Filed: 1989-12-18
Granted: 1994-05-24
Abstract: WELL PACKING SYSTEM               ABSTRACT OF THE DISCLOSURE The present invention pertains to a packing structure and method of packing which can be used in the wellbore of injection wells for the recovery of heavy oils, shale oils, and tars, and in well shafts for in-situ coal gasification.  The packing can also be used in the wellbore of gas and light oil production wells.  The packing is used to provide passive protection of well structural components in the event of a well fire or fire in the formation near the well.         The packing is placed in the well shaft below ground level, and preferably below the well packer.  The packing particle size, as related to the well casings, is a critical feature of the invention.  Particle size distribution, and position of placement of packing in the wellbore as a function of packing particle size, are significant variables which can be tailored to the application. The packing material is non-combustible under anticipated conditions which will occur in the well in the event of a fire and can be endothermic to provide increased efficiency.

Granted: 2001-03-20
Abstract: A feedforward predistortion equalizer includes a first loop with a signal divider for dividing signals into first and second portions, and a distortion generator for distorting the second signal. The first loop is completed by a signal combiner which combines the undistorted first signal and the distorted second signal. The phase and amplitude of the signals in the loop are controlled so that the linear or carrier signal component is cancelled, leaving at the output of the first combiner only the distortion component of the distorted signal. A second loop includes phase and amplitude controls for combining the pure distortion and undistorted signals to produce the desired predistorted signals. In a particular embodiment, the phase and amplitude controls of the first loop are automatically adjusted for a null.

Title: Method of restoring the correct cell sequence, particularly in an atm exchange, and output unit therefor
Inventor: SCHRODI KARL
IPC: H04L12/56
Filed: 1990-12-20
Granted: 1994-02-01
Abstract: Abstract Method of Restoring the Correct Cell Sequence, Particularly in an ATM Ex-change, and Output Unit therefor It is known that, to be able to load an ATM switching network as uniformly as possible (also for short periods of time) and, thus, keep costs low, the successive cells of one and the same connection are routed to the output by as many different paths as possible.  A problem with this is that mutual overtaking of successive cells must be avoided or corrected.  In the present invention, each cell is held at the output until it is certain that no older cell can be buffered in the switching network. before the cell is passed on, a check is made to determine whether the cells received from the switching network later include an older cell which must be passed on before that cell.  At the input end, consecutive numbers ("Sequence Numbers") are allocated to the cells (on a per-connection basis or not).  A buffer at the output end is operated, at least in part, in the manner of a shift register, thereby introducing a predetermined delay.  Prior to the output of a cell, at least the shift-register-like portion of the buffer is examined as to whether a cell written in later is to be put out earlier, if so, the two cells are interchanged.

Title: Method and pulling plug for installing a cable in a cable conduit
Inventor: GRIFFIOEN WILLEM
IPC: G02B6/44
Filed: 1991-02-25
Granted: 1996-05-28
Abstract: The invention comprises an improved method for installing a cable (4) in a tubular cable conduit (6) with the aid of the drag forces of a flowing medium and a pulling plug which can be used in this method. Coupled to the foremost end (8) of the cable in the conduit is a partially leaky pulling plug (10) which is provided with a flow opening (12)  for the flowing medium. Said flow opening (12) is so dimensioned that, on the one hand, no harm is done to the drag forces of the flowing medium along the cable  (4)  but,  on the other hand,  a small pressure difference is maintained across the pulling plug, with the result that the pulling plug (10) energised in this way exerts additional tensile forces on the foremost end (8) of the cable (4) which compensate at least at that point for compressive forces arising as a consequence of intrinsic curvatures. Said flow opening is preferably such that during the installation of a cable the flow velocity in the flow opening (12) is essentially equal to that of sound in the flowing medium (shock wave condition). The flow opening (12) can be chosen as constant, but may also be regulated in a pressure-dependent manner to maintain the said shock wave condition better. Three embodiments of such a partially leaky pulling plug (10) are described, namely one having a constant flow opening, one in which the size of the flow opening varies with an essentially constant pressure difference across the pulling plug and one in which the size of the flow opening varies with the pressure at the position of the pulling plug. The pulling plug preferably has a circumferential suction seal with the inside wall (11) of the conduit (6). Advantages are reduction of the risk of upsetting and buckling, generally greater installation lengths in one stroke, and a lower compressor power.
