Patent CA-2071952-A1 (CA)
Title: An article having a high friction surface, an apparatus and a method for producing said article
Inventor: NEFF CHARLES
IPC: B24D3/08
Filed: 1990-12-20
Abstract: A product and a process for producing a matrix and a tool for use in abrasive or cutting applications including a base tool structure which may be armed with a plurality of triangular or conically shaped structures (24B) consisting of abrasive particles (32) bonded together in a braze metal (38). The structures (24B) may be prepared in a manner which provides a selectable rake angle. Rake angles including negative (46), neutral (46') and positive (46") may be produced. The process is accomplished by dif-fusing magnetizable abrasive particles on a release mechanism which has been placed on a reusable fixture (10) consisting of a plurality of balls (16) secured to a magnetized surface (14). The particles (32) stack to form structures (24) which are then encap-sulated in a braze paste (26). The axis of the structures (24) is aligned with the applied magnetic field, The cones are symmetrical if the magnetic field emanates perpendicularly from the magnetized surface. If the orientation of the magnetic field is distorted the conical structures will realign themselves therewith. In this manner conner conical structures (24) may be formed which offer selectable rake angles. The matrix (22) foamed by encapsulating the abrasive particles (32) may be removed from the release me-chanism (18) and secured to a base structure (30). Once this assembly has been brazed, the base structure may be used as an abrading or cutting tool.

Inventor: HORTON HARRY M
IPC: B41J13/10
Filed: 1992-07-14
Abstract: An apparatus is provided to secure a facsimile machine and provide a secure receptacle portion adapted to receive and retain paper output from facsimile machines, so as to ensure the security and confidentiality of paper output from facsimile machines, so that the paper output is not accessed or readexcept by persons authorized to do so. The apparatus accommodates the usual operating function of a facsimile machine such as inputting paper having writtenmessages to be sent elsewhere and receiving the paper output of messages received from elsewhere. A base portion supports the facsimile machine on a horizontal surface and secures it thereto. A cover portion generally covers the facsimile machine and precludes it from being removed from the base portion. The receptacle portion and the cover portion are moveable with respect to each other so as to provide selectively securable access to the interior of the receptacle, being limited only to those who have a key or other means to open the receptacle. The cover for the entire apparatus also serves to secure the facsimile machine against unwanted or unwarranted removal away from its position.

Title: Fibroblast growth factor receptors
Inventor: DIONNE CRAIG A
IPC: C12N1/15
Filed: 1991-07-03
Abstract: The complete cDNA cloning of two human genes previously designated flg and bek is disclosed. These genes encode for two similar but distinct surface receptors comprised of an extracellular domain with three immunoglobulin-like regions, a single transmembrane domain, and a cytoplasmic portion containing a tyrosine kinase domain with a typical kinase insert. The expression of these two cDNAs in transfected NIH-3T3 cells led to the biosynthesis of protein of 150 kDa and 135 kDa for flg and bek respectively. Direct binding experiments with radiolabeled acidic FGF (aFGF), basic FGF (bFGF), or kFGF inhibition of binding with native growth factors, and Scatchard analysis of the binding data indicated that bek and flg bind aFGF, bFGF, or kFGF with dissociation constants of (2-15) × 10 -11 M. The high affinity binding of three distinct growth factors to each of two different receptors represents a unique double redundancy without precedence among polypeptide growth factor/receptor interactions. The use of transformed host cells overexpressing flg or bek or biologically active fragments thereof for drug screening is disclosed.

Inventor: CACI JOSEPH C
IPC: H04N7/00
Filed: 1993-05-13
Abstract: A communications processor serves a group of several workstations with audio and video transmission processing for the purpose of providing video conferencing. The communication processor utilizes artificial intelligence software to read the connection. Conversion rules contained in tables so that the system can react to the communications environment. The system is coupled for processing optical signals for low cost communication and video conferencing with audio and video communications within the facility area and for long haul transmission. The communication processor provides audio and video communications under instantaneous constraints of the transmission medium and instantaneous degree of loading or usage. Bandwidth, resolution and transmission rate are adjustable to fit the constraints at the time a request for service is made. A workstation initiates a request for service. A request for service includes data about the nature or type of service and signal destination. This information is sufficient for the communication processor to make several attempts to threads before an affirmative determination can be made. If an affirmative determination is not possible, then the communication processor will determine which is possible and provide an output to the user for possible changes in a request.

Title: Waveguide optical pick-up head using mach-zehnder interferometer wavefront sensor apparatus and method
Inventor: REVELLI JOSEPH F JR
IPC: G11B7/12
Filed: 1993-06-22
Abstract: WAVEGUIDE OPTICAL PICK-UP HEAD USING MACH-ZEHNDER INTERFEROMETER WAVEFRONT SENSOR APPARATUS AND METHOD                 ABSTRACT OF THE DISCLOSURE    An integrated optic head contains a planar and channel waveguides, a waveguide condensing lens, and integrated waveguide photodetectors.  The main portion of the beam returning from the disk is focused by the lens onto an integrated waveguide photodetector to provide the data signal.  A smaller portion of the beam is sampled by channel waveguide Mach-Zehnder (MZ) interferometers that measure the beam wavefront curvature to provide the focus error signal (FES). Additional channel waveguides provide reference signals for the interferometers and provide a means of measuring the tracking error signal (TES).  The TES method includes subtracting light detected by one channel waveguide detector from light detected by another, which difference is the tracking error.  The FES method includes obtaining the difference in the ratios of the light emanating from two interferometers divided by the light emanating from their respective channel waveguides, which difference in ratios is the focus error.

Title: Optical fiber feed system for a phased array antenna
Inventor: GAZDEWICH JEROME D
IPC: H04B10/25
Filed: 1993-07-19
Abstract: ABSTRACT        A signal feed system for a phased array antenna having a plurality of antenna elements arranged in an array with each antenna element being connected to a transmit/receive T/R module, the system having transmitter and receiver Tx/Rx equipment with an optical fiber signal feed between the Tx/Rx equipment and the T/R modules.  A first opto-electronic interface converts signals from transmitter Tx to optical signals which are applied, via an optical fiber, to an optical coupler that couples those optical signals to a first group of optical fibers, each of which is connected to another opto-electronic interface where the optical signals are converted to electric signals and applied to the transmitter T in an associated T/R module which feeds an appropriate signal to its associated antenna element.  Signals received by each antenna element are applied to a receive section R in a r/R module and then, from the receiver, to an associated opto-electronic interface where they are converted to optical signals and transferred by optical fibers in a second group of optical fibers to a second optical coupler that transfers those signals to the first opto-electronic interface.  The first opto-electronic interface then converts those received optical signals into electrical signals that are applied to receiver Rx in the Tx/Rx equipment.  This design allows for the use of a single high power laser as an optical carrier whose light can be remoted (i.e. distributed)to all the opto-electronic interfaces so that the optical carrier at each will be of the same wavelength.
