Patent CA-2116255-A1 (CA)
Inventor: FLANAGAN RICHARD T
IPC: H04B7/005
Filed: 1994-02-23
Abstract: PREDISTORTION TECHNIQUE FOR COMMUNICATIONS SYSTEMS Abstract The problem of noise enhancement is eliminated in communications systems by predistorting the amplitude of the transmitted information signal in a manner which compensates for the amplitude distortion introduced in a portion ofthe communications channel. In the disclosed embodiments, the communications system includes two signal transceivers which communicate with one another through a communications channel. The communications channel includes two-wire subscriber loops adjacent to each signal transceiver with a four-wire transmission path disposed between the subscriber loops. Each transceiver transmits an information signal which, depending on the system noise characteristics, is predistorted to compensate for all or a portion of the amplitude distortion introduced in a subscriber loop adjacent to that signal transceiver. The predistortion necessary to provide such compensation is determined at each transceiver in response to a received narrowband signal at that transceiver. Advantageously, this narrowband signal may be that used to disable echo cancellers and/suppressors in the communications channel.

IPC: G02B6/44
Filed: 1994-09-02
Abstract: A rotation sensor for use in a fiber optic gyroscope includes a substantially-planar disk-like coil mounting member of titanium.  A wound sensor coil is supported by the member in an edgewise fashion, allowing free expansion of the sensor coil in the direction orthogonal to the plane of the member to minimize thermally-induced stressing of the sensor coil.  In an alternative embodiment, the free-standing coil is effectively "split"; that is, one-half is mounted to one side of the member and the remainder to the other side in such a way that the sensitive axes are coincident.  Edge ramps are provided in the member for guiding the continuous optical fiber comprising the coil segments from one side of the disk-like mounting member to the other without microbends.  A cylindrical inner hub includes a thinned and flexible portion for contacting a mounting pedestal of stainless steel composition whereby the differential thermal expansions of the pedestal and mounting member materials will not produce misalignment of the sensor coil with respect to a predetermined input axis of rotation.

Title: Granular urea-based fertilizer
Inventor: WESTON CHARLES W
IPC: C05C9/00
Filed: 1994-10-11
Abstract: ABSTRACT    An improved homogenous granular fertilizer composition is disclosed; the composition is comprised primarily of urea, N-(n-butyl)thiophosphoric triamide (NBPT), and dicyandiamide (DCD). The composition of this invention can be applied to a field crop in a single surface application and will nevertheless supply sufficient nitrogen to the plants throughout their growth and maturing cycles.          The new improved composition increases the nitrogen uptake by plants,  enhances crop yields,  and minimizes the loss of both ammonium nitrogen and nitrate nitrogen from the soil.    The  NBPT is  incorporated  into  the  homogenous  granular fertilizer composition of this invention by blending a concentrated solution of NBPT in a solvent selected from the group consisting of liquid amides, 2-pyrrolidone, and N-alkyl 2-pyrrolidones directly into molten urea prior to its granulation; the DCD may be added to the urea melt as a solid or in dissolved form along with the NBPT.

Abstract: ABSTRACT OF THE DISCLOSURE          In a method and apparatus for manufacturing a slide fastener chain having rows of coupling elements and members of a separable bottom end stop assembly, two positioning holes are formed at predetermined positions on reinforcing films attached to a pair of fastener tapes. The positioning holes are used to position the fastener tapes relative to a molding unit with respect to each individual slide fastener length. Thus, even when a positioning error is produced due to a change in tension on the fastener tapes being processed, such error is limited to a small extent which is created only in the individual slide fastener length. Thus, the coupling elements and the first pin member and the second pin member can be molded precisely. Additional to its primary positioning function, the positioning holes further have a  function to provide a reference when a pair of U-shaped cutout portions is formed in the fastener tapes to facilitate smooth and reliable attachment of a box relative to the first pin member and the second pin member, and also have a function to provide a reference when the slide fastener chain is cut off at the cutout portions transversely across the fastener tapes.

Title: Method and apparatus for presenting stereoscopic images
Inventor: DEAN DAVID MICHAEL MOORE
IPC: G02B30/25
Filed: 1993-12-08
Abstract: Stereoscopic images are presented by alternately displaying corresponding left eye and right eye images in succession, substantially extinguishing transmission of light from the left eye images to the right eye of a viewer and from the right eye images to the left eye of the viewer, for example by the use of polarizing filters (2, 6), and alternately and in synchronism with the alternate display of images, scattering unextinguished light from the left eye images that leaks through to the viewer's right eye and from the right eye images that leaks through to the viewer's left eye. In a preferred embodiment, scattering is achieved by using a liquid crystal scattering shutter (10, 12) that is electrically triggered in synchronism with the display of images. The shutter disperses the unextinguished light that leaks through the system so that no image information is perceived and the light appears merely as a slight increase in background illumination.
