Title: Diagnostic assay for breast cancer susceptibility
Inventor: RESTA REGINA
IPC: C12Q1/6886
Filed: 1997-11-06
Abstract: The lifetime probability of a woman developing breast cancer can now be determined based on an allelic variation found in the 3'UTR of the prohibitin gene. The probability is dependent on the sequence of the 3'UTR at position 729, i.e., whether there is a thymine (T) or a cytosine (C) or both at this position. Polymorphism at position 729 is also disclosed as a susceptibility indicator for hereditary breast cancer in men. Determining the sequence at the position 729 can be done by any number of standard techniques. Preferably, the sequence is determined by amplifying this region by PCR and subjecting it to an RFLP analysis.

Title: Method and apparatus for harvesting crops
Inventor: PARSON KENNETH ROSS
IPC: B07B7/08
Filed: 1999-06-09
Abstract: A method and system of harvesting crops involves cutting and threshing the crop, separating graff (a mixture of grain kernels, chaff, weed seeds, and other organic matter) from straw, and returning the straw to the field.  This is carried out in a harvesting unit of the pull type having a large graff storage tank. The collected graff is moved to a cleaning mill in a different location by means of a suitable vehicle such as a truck. The storage capacity of the harvesting unit should be no larger than the carrying capacity of the truck. Similarly, the throughput of the cleaning unit should be able to process graff (separate grain kernels from the remainder of the graff) at a rate at least as fast as the rate at which graff is delivered to the cleaning mill. The method allows for efficient harvesting, transportation and cleaning of graff. The invention relates also to improvements of the harvesting unit and the cleaning mill.

Patent CA-2282814-A1 (CA)
Inventor: MACDUFF JAMES
IPC: F16L33/207
Filed: 1999-09-21
Abstract: A tubing connector seals an end portion of a tubing that serves as a conduit for fluids. An elastic seal ring is provided in each of two annular grooves in an external periphery of a connector portion of the tubing connector. Each groove has a depth that approximates a thickness of the seal ring and a width greater than a width of the seal ring. When the connector portion is inserted in the tubing and a radial pressure is exerted on the tubing by a crimp ring, the plastic inner periphery of the tubing intrudes into each annular groove and further compresses the seal ring inwardly in the groove. The remainder of the tubing overlapped by the crimp ring is compressed tightly around the external periphery of the connector portion to form a fluid-tight seal.

Title: Containment structure and method of manufacture thereof
Inventor: FITZPATRICK P JOHN
IPC: B63B25/14
Filed: 1999-09-22
Abstract: A marine gas storage and transport system formed of small diameter steel pipe, which is coiled and stacked in a specific manner. The system is suitable for use on top of a barge or inside the holds of a ship, when contained within a secondary containment system. The specific manner in which the pipe is coiled is such that about 97%  of the total length of pipe coiled may be described by constant curvature or pure circles.  Additionally these circles lie directly on top of one another about 94% of the time and vertical stacking stresses are minimized. Only about 6% of the pipe is involved in crossover geometry. This method, of about 97% circular coiling, combined with about 3% transitional coiling results in a continuous length of pipe that nests easily, provides greatly reduced contact stresses and is very economic to construct due to its ease of nesting and it's long lengths of constant curvature. Descriptions of the marine transport system or the coil containment system are not included since they are described in related patents.

Title: Apparatus for separating components in well fluids
Inventor: HOMAN EDWIN DARYL
IPC: E21B21/06
Filed: 1996-08-28
Abstract: A system for separation of fluids and drill cuttings received from a borehole during an under-balanced drilling procedure. The system is designed to cope with significantly varied pressures and flow rates, particularly in relation to gas content of drill fluids returned to the surface during the drilling process in a production zone, and to provide effective separation and to reduce the detrimental effect due to the presence of the drill cuttings in the returned drill fluids. In the present invention there is utilized a first stage, high pressure vessel in which a major portion of the gases ad drill cuttings are separated, and a second stage, horizontal low pressure vessel, preferably of greater volume than the high pressure vessel, in which further separating is achieved, including the separate removal of the drilling liquid to be returned to the drill tube. Because in under-balance drilling, the most serious variation in the pressure of the returning fluid is due to rapid increases in the proportion of gases in the drill fluid, the system of the present invention includes features allowing the control of the operating pressure in the high pressure vessel by way of the flow control of the gases exiting the high pressure vessel while the remaining separating procedure continues to provide effective results.

Title: A method of and apparatus for selecting base stations to communicate with a remote station
Inventor: SOLIMAN SAMIR S
IPC: H04B7/26
Filed: 1998-07-21
Abstract: A mobile station (2), for use in a communication system compris-ing plural base stations (4) controlled by a base station controller (6), com-prises a receiver (50, 52, 54) for re-ceiving signals from plural base sta-tions which together comprise a set of candidate base stations. The mo-bile station determines power in the received signals, and compares the power with a first threshold value.  The mobile station (2) identifies base stations (4) whose signals have a re-ceived power greater than the first threshold value and transmits a sig-nal to the controller (6) representing identified base stations as being suit-able for inclusion in an active set.  The measured pilot energy of each pilot in the candidate set is iteratively compared against a threshold gener-ated in accordance with the sum of the energies of the pilots in the ac-tive set. If the strongest pilot in the candidate set satisfies this threshold condition, it is added to the revised active set. A second iterative process is performed to determine whether a pilot should be deleted from the revised active set. The mobile station (2) determines whether a change to the current active set is desirable by measuring the energies of the pilots in the active set and the candidate set, and dynamically adjusting the necessary thresholds based on its own estimation of the communication environment.
