IPC: G01D5/20
Filed: 1998-04-24
Abstract: An angular displacement transducer has a highly magnetically permeable target which preferentially directs the flux of a fluctuating magnetic field through one of two or more cores. The fluctuating magnetic field includes voltages in secondary windings around the cores. Output signals which vary with the angle of the target about an axis are obtained by connecting pairs of secondary windings differentially. By choosing targets of different shapes the output voltage can be made to vary with angle as a sine wave or as a triangular wave.  Transducers according to the invention can be rugged and accurate while retaining a simple construction.

Title: Alpha 1a adrenergic receptor antagonists
Inventor: BOCK MARK G
IPC: A61K31/421
Filed: 1998-06-17
Abstract: This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as alpha 1a adrenergic receptor antagonists.  One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved.

Patent CA-2296422-A1 (CA)
Inventor: DE BOER ANTHONY
IPC: B01D39/08
Filed: 2000-01-19
Abstract: A filter structure, typically for in ground use on perforated pipes, in which a tubular knit fabric is used, thus providing the elasticity inherent in a knit construction, but the yarns of the fabric are napped or suaded, cutting filaments from them. The filaments extend across the stitch opening, reducing the micron size rating of the filter without the need to use more and costly yarn. Preferably the filaments are cut from additional laid-in yarns while leaving the base or ground structure of the fabric intact and hence unweakened. The napping or suading can be on the inside or outside of the filter fabric. The filter can be used for gases as well as liquids and can be on flat sheets as well as in tubular form.
