Title: Steroid sulfamates, method for the production and use thereof
Inventor: SCHUMANN WINFRIED
IPC: A61P15/12
Filed: 1998-03-18
Abstract: The invention relates to novel estratrienes of general formula (I) containing several sulfamoyoxy groups per molecule (m = 1-5).  They are produced by reacting the appropriate steroid alcohols with sulfamoy or n-alkyl or alkanoylsulfamoyl chloride in the presence of a buffer or a base. The compounds of formula (I) are characterized by a high sulfatase activity and are therefore suitable for the treatment of diseases responding to sulfatase inhibition. The high target specificity of the inventive compounds in relation to sulfatase and estrogen transcription assays enable said compounds, which are provided with a radiolabel e.g. [18F] fluorine instead of F, to be used as potential markers in tumor diagnosis.

Title: Radio calibration by correcting the crystal frequency
Inventor: DELL AERA SESTE
IPC: H03L7/197
Filed: 1999-11-02
Abstract: The present invention provides a simple and inexpensive method of calibrating radios. The present invention automatically corrects for crystal frequency drift by determining the true crystal frequency. once the true crystal frequency has been measured and calculated, the proper multiplier required to produce a desired frequency can easily be found and implemented.      The present invention allows for a constantly changing desired frequency without recalibration and without readjusting the crystal frequency once the true crystal frequency is known. Once the true crystal frequency is found, a proper multiplier can be calculated to produce the desired frequency. Continuously adjusting the multiplier thus allows for a changing desired frequency, thereby facilitating clear communications between radios, regardless of whether they are in motion or not.
Patent CA-2289212-A1 (CA)
Title: Active phase splitter
Inventor: APARIN VLADIMIR
IPC: H03F3/45
Filed: 1998-05-21
Abstract: An active phase splitter (100, 102) comprises two or more phase shift circuits (110, 150). Each phase shift circuit comprises a number of active devices (112, 114, 152, 150) and capacitors (116, 156, 158).  For a single-pole active phase splitter, within each phase shift circuit, two active devices are configured as a cascode amplifier. The first active device is configured as a common source amplifier and the second active device is configured as a common gate amplifier. A  capacitor (116, 156) is connected across the gate and drain of the first active device to generate the necessary pole-zero pair for the phase shift circuit. The cascode configuration results in the desired transfer function and provides transconversion of voltage input (VIA) to current outputs (Ia, Ib). Active phase splitters with two or more poles can be built using the same inventive concept.

The method is particularly suitable for use in the automated production and attachment of a loop to an implantable device (12) used in the implantation of a prosthetic ligament.
Patent CA-2291991-A1 (CA)
Title: Junk basket and method of use
Inventor: SHKURTI PIRO T
IPC: E21B33/134
Filed: 1999-12-10
Abstract: A junk basket comprises a sleeve sized to fit within a well bore. The sleeve has a bore therethrough, an internal latch at its top end for connection to a complementary retrieval tool having an external latch. A basket floor is movable axially in the bore between a first position intermediate the axial length of the sleeve, and a second position resting on a retaining shoulder at the bottom of the sleeve. In a well bore, the basket floor is supported at the first position, preferably on a retrievable bridge plug, and debris is collected in the defined volume above the floor. When the basket is lifted during retrieval, the basket floor falls to the second position, increasing the collection volume, loosening the debris and loosening the basket in the well bore for ease of retrieval. Further, a novel method of jointly deploying a junk basket and bridge plug results. The basket is connected to the plug and a setting/insertion tool passes through the basket's bore and through a port in the basket floor. Once the plug is set in the well bore the setting tool is removed. By lifting the retrieving tool with a predetermined load over string weight, the basket is sheared from the plug, a ball engages the port in the floor and the floor falls, loosening the debris and basket in the well bore.
