Patent CA-2080011-A1 (CA)
Title: Interferometric signal analysis with modulation switching
Inventor: FERRAR CARL M
IPC: G01C19/72
Filed: 1991-06-11
Abstract: In a fiber optic rotation sensor, two phase modulators are symmetrically offset with respect to the center of an optical fiber loop and alternately excited by a waveform whose frequency alters the differential phase between counter-propagating light waves in the loop to maintain a fixed intensity signal at a detector upon lo op rotation. The difference between the waveform frequencies is proportional to the speed of sensor rotation while the mean value of the waveform frequencies equals the frequency value in the absence of sensor rotation. In the alternative, a single modulator is excited by a waveform whose polarity is reversed at intervals of time.

Title: Self converging wide screen color picture tube system
Inventor: MILILI MARC
IPC: H04N5/68
Filed: 1991-05-10
Abstract: A self converging, widescreen color picture tube system includes a widescreen, in-line color picture tube having a funnel, an electron gun assembly (28) for three in-line electron beams located in a neck at one end of the picture tube, and a faceplate with a viewing screen at the other end. The picture tube has a wide aspect ratio. A self converging widescreen deflection yoke (40) for deflecting the electron beams in the wide aspect ratio picture tube includes horizontal and vertical deflection windings. The yoke (40) is located by an initial flare section of the funnel and positioned along the longitudinal axis of the picture tube to make the tube reference line and the yoke deflection plane substantially coincident. To achieve substantial horizontal astigmatism cor-rection at the extremes of the major axis of the wide viewing screen, the horizontal deflection winding is constructed to have a generally pincushion-shaped horizontal deflection field over the effective length of the field. The field is modified from that re-quired of the horizontal deflection field in a comparable self converging narrowscreen yoke. The modification is made in accord-ance with the differences in centerscreen slope angles and S-spacing.

Title: Inducible lymphoid specific protein tyrosine phosphatase
Inventor: MAK TAK W
IPC: C07H21/00
Filed: 1992-12-29
Abstract: Abstract of the Disclosure Tyrosine phosphorylation and dephosphorylating event have been shown to be central to the process of growth regulation and signal transduction.  The invention is the identification of a new gene with a tyrosine phosphatase domain (EC 3.1.3.48) which is expressed exclusively in thymus and spleen.  A cDNA of 2760 bp encodes a 339 amino acid, intracellular, single domain tyrosine phosphatase.  When expressed as a glutathionine-S-transferase fusion protein, efficient lysis of p-nitrophenyl phosphate is noted, indicating in vitro enzymatic activity of the cloned gene product.  Normal mouse lymphocytes increase mRNA expression 10-15 fold upon stimulation with phytohemaglutinin, concanavalian A, lipopolysaccharide or anti-CD3 monoclonal antibody.  This new hematopoietic tyrosine phosphatase, (HePTPase), may play a role in the regulation of T and B lymphocyte developement and signal transduction.

Title: Apparatus and process for controlling the flow of a metal stream
Inventor: MOURER DAVID P
IPC: B22F9/08
Filed: 1993-01-21
Abstract: APPARATUS AND PROCESS FOR CONTROLLING              THE FLOW OF A METAL STREAM                 ABSTRACT OF THE DISCLOSURE An apparatus that controls the flow of a stream of metal, such as produced from the bottom of a hearth, includes a cylindrical metallic nozzle body having a hollow wall which includes a slit extending substantially parallel to the axis of the cylinder so that there is no electrical continuity around the nozzle wall across the slit.  The walls of the cylinder are preferably formed of hollow tubes through which cooling water is passed.  A sensor senses a performance characteristic of the apparatus, such as the temperature of the nozzle body.  An induction heating coil surrounds the nozzle body, and a controllable induction heating power supply is connected to the induction heating coil to provide power.  A controller controls the power provided to the induction heating coil by the induction heating power supply responsive to an output signal of the sensor, so that a selected performance characteristic of the apparatus may be maintained.

Inventor: HOLLIER MICHAEL P
IPC: H04M1/19
Filed: 1991-09-05
Abstract: A noise-cancelling telephone handset comprises a housing defining an earpiece (2) and a mouthpiece (3) housing a first order pressure gradient microphone (m). The housing is pro-vided with two pressure-sensing locations (h1 and h2) in the region of the mouthpiece (3), these locations being connected to the microphone (m) by ducts (5). The pressure-sensing locations (h1 and h2) are spaced apart by a predetermined distance which is sufficiently large to permit locally-generated speech signals to produce a pressure gradient between the pressure-sensing locations whilst sound signals from distant sources produce substantially equal pressures at the pressure-sensing locations, whereby, in use, the output from the mouthpiece is substantially entirely that resulting from the locally-generated speech sig-nals.

Filed: 1991-09-26
Abstract: CHARACTER RECOGNITION METHODS INCLUDING SEPARATING AND   EXTRACTING PARTICULAR PORTIONS FROM EXTRACTED DATA          By Norbert Klenner ABSTRACT OF THE DISCLOSURE:         A method for recognizing amount data characters contained on a document, such as the courtesy amount (10b) on a check (10).  The courtesy amount (10b) typically comprises a dollar portion (10b-2) and a cents portion (10b-1).  Recognition of the courtesy amount (10b) is accomplished by investigating an image of the document area containing the courtesy amount to derive a separation characteristic between dollar and cents portions, such as a period (Fig. 14, PC) or a fraction (Fig. 17).  The separated cents portion is then categorized, and the cents characters derived based on the determined category, following which the characters of the dollar portion are recognized.

Abstract: A double lead-pup trailer assembly for container transport has swivel bunks enabling the container to be carried on the articulated trailers.  The rear swivel bunk slides rotatably within a slot extending to the rear of the pup trailer allowing the container to be directly unloaded.  The coupling means between the trailers is adjustable between a highway articulated driving relationship, and a backing up aligned relationship.  One advantage is the gross vehicle weight and payload are improved.  Another advantage is that the container more closely tracks the tractor and trailer wheels on turns, thus providing more manoeuvrability and safety.
