Title: Method and system for the early detection of the jamming of a core sampling device in an earth borehole, and for taking remedial action responsive thereto
Inventor: RAO M VIKRAM
IPC: E21B21/08
Filed: 1994-05-25
Abstract: ABSTRACT OF THE DISCLOSURE A drill string having a core sampling device at its lower end is suspended in an earth borehole by a rotary drilling rig at the earth's surface. Drilling fluid pulsations are monitored in the drilling fluid standpipe to generate characteristic signatures of normal coring operations and a precursor, abnormal, signature when the core sampling device first begins to jam, before catastrophic jamming has occurred. Responsive to the abnormal signature, remedial action is commenced, such as reducing WOB, RPM, or terminating the coring operation. The system is also used to determine that an activatable downhole tool has one or more of its parts moved from a first position to a second position.

Title: Vibrator for Transporting Articles
Inventor: SAHLBERG KARL M
IPC: B65G27/14
Filed: 1994-06-29
Abstract: A vibrator is provided herein for transporting articles. The vibrator has a base, a sliding carriage having an article-carrying surface, and a piston arrangement disposed in a piston cavity for reciprocating movement in opposite directions between two positions, the piston arrangement bearing on the carriage. At least one seal is disposed between the piston arrangement and the piston cavity. The piston arrangement, the seal and the piston cavity form two expansion chambers that are respectively enlarged and contracted with movement of the piston arrangement. The manifold communicates with the inlet, with the vent, and with the expansion chambers for supplying air to, and exhausting air from the expansion chambers. A mechanism is disposed outside of the expansion chambers, which is associated with the manifold and is operated by the piston arrangement to move between a first position, in which one expansion chamber communicates with the inlet and in which the other expansion chamber communicates with the vent, and a second position, in which one expansion chamber communicates with the vent and in which the other expansion chamber communicates with the inlet. In this manner, the piston arrangement is reciprocated. Regulating means are associated with one of the expansion chambers, for regulating air flow into one expansion chamber or air flow out from one expansion chamber. By such regulations, the piston arrangement and the carriage move relatively more forcefully in one of the opposite directions than the other of the opposite directions. Articles on the article-carrying surface are thus transported in a direction opposite thereto. In this way, articles on the article-carrying surface are incrementally displaced in the direction opposite to the more forceful stroke.

Filed: 1994-09-14
Abstract: A driving method of the present invention drives a semiconductor laser which is provided with at least first and second electrodes through each of which current is injected into the semiconductor laser. Varying current is injected through the first electrode when the frequency of the varying current is in a high frequency band.  Varying current is injected through the first electrode while phase-shifted current, whose phase is shifted relative to the varying current, is injected through the second electrode, when the frequency of the varying current is in a low frequency band which is lower than the frequency of the high frequency band.  Feedback-control may be performed for controlling a ratio between amplitudes of the modulation current and the phase-shifted current based on a light output from the semiconductor laser.  The varying current includes at least modulation current modulated according to a predetermined signal or negative feedback current produced by an electric signal obtained by detecting fluctuation of oscillation wavelength of a light output from the semiconductor laser. Thus, an optical signal radiated from the laser can be desirably stabilized over a wide frequency band range.

Title: Automatic control system of lights in a series circuit illumination plant, in particular lights for airport signalling
Inventor: PAVAROTTI REMO
IPC: H05B37/03
Filed: 1993-07-20
Abstract: This invention concerns an automatic control system for lights in a series circuit illumination plant, in particular lights for airport signalling or lamps for road lighting, motorway lighting or for private areas (large industrial areas). It is characterised in that it is physically distinct from the work circuit feeding the lights and galvanically separate from the latter. This system allows the lights to be switched on and off, and more importantly allows them to be switched on and off individually and not all together. This system permits one to have an always up-to-date picture of the state of operation of all the lights and is predisposed for activating alarms if necessary, or indication of breakdown for the human operator. Since all devices able to recognise and distinguish the type of vehicules which move on various airport runways and taxiways may also be connected to it, this system is proposed as a complete system for running airport ground traffic.
Patent CA-2143948-A1 (CA)
Title: Distributive Communications Network
Inventor: SMITH PHILIP J
IPC: H04B10/035
Filed: 1993-09-08
Abstract: A distributive communications network comprises groups of nodes (11-22, 31-36, 41-43, 51) at different levels (1, 2, 3, 4). Each set of nodes at one level is connected to an associated node in the level above for transmission and reception of traffic. Traffic is assigned to one of a number of bands of wavelengths according to whether it is local or wider area traffic. At the first level of node (11-22) local area traffic in the corresponding band of wavelengths is looped back and retransmitted to all of the terminals (a-x) that are connected to that node. At each level of node, traffic is either passed on to a higher level, or looped back according to the band of wavelengths to which it is assigned. Thus, the wavelength band determines the node level at which the traffic is looped back, and the breadth of terminals ultimately exposed to this traffic. It is possible to re-use bands of wavelengths for communicating between terminals.

Title: Bayesian Sequential Indicator Simulation of Lithology from Seismic Data
Inventor: DOYEN PHILIPPE M
IPC: G01V1/30
Filed: 1995-03-10
Abstract: A discretized lithologic model of the subsurface is defined by a regular array of pixels. Each pixel corresponds to one of a finite number of possible lithoclasses such as sand, shale or dolomite. The lithoclasses are unknown except at a small number of sparsely distributed control pixels associated with borehole locations. Associated with each pixel there is a multivariate record of seismic attributes that may be statistically correlatable with the local lithology. A Monte Carlo method is used to simulate the lithoclass spatial distribution by combining the lithologic data at control pixels with the seismic-attribute data records. Using Indicator Kriging, a prior probability distribution of the lithoclasses is calculated for each pixel from the lithology values at neighboring pixels. The likelihood of each lithoclass is also calculated in each pixel from the corresponding conditional probability distribution of seismic attributes. A posterior lithoclass probability distribution is obtained at each pixel by multiplying the prior distribution and the likelihood function. The posterior distributions are sampled pixel-by-pixel to generate equally probable models of the subsurface lithology.
