Title: Device for transmitting torque between two rotatable shafts
Inventor: LUNDSTROEM BO
IPC: F16D43/284
Filed: 1994-03-14
Abstract: A device for transmitting torque between two rotatable, co-axial shaft members (1, 2) in a stationary housing (4) has a clutch (11, 12) engageable to counteract differential rotational speed between the shaft members. A hydraulic clutch piston (14) is arranged to engage the clutch, and a hydraulic pump arrangement (1'; 18 - 21, 11", 14 - 17), driven by the speed differential between the two shaft members, creates a hydraulic pressure on the clutch piston.       The hydraulic pump arrangement includes a supply piston (18) and the clutch piston. Rollers (17, 21) are rotatable with one of the shaft members (2) and engage the other of the shaft members (1) via cams (1', 11"), which are angularly offset in relation to each other, so as to impart to the pistons a reciprocating movement at the differential rotational speed between the shaft members. A hydraulic line system (25, 27, 29, 31) connects a cylinder (23) at the supply piston on one hand with the tank (24) via a check valve (26) and on the other hand - via a line (27) with a check valve (28) - with an outlet line (31) and connects a cylinder (30) at the clutch piston (14) with the outlet line.

Title: Determining optical signal transit delay time in an optical interferometer
Inventor: FERRAR CARL M
IPC: G01R33/032
Filed: 1992-04-07
Abstract: In a fiber optic gyroscope (10) having a pair of light waves counter-propagating in a fiber optic loop (44), a phase modulator (28) driven with a variable frequency and amplitude modulation signal on a line (32) so as to null any rotation induced optical phase shift; and using the difference between the drive frequency and the loop eigenfrequency as a measure of rotation rate, is provided with a calibration circuit (34) which determines the actual loop eigenfrequency while in rotation. A modulation signal is applied having an amplitude that causes the closed loop output frequency to equal the loop eigenfrequency independent of rotation rate. The amplitude is fine tuned by applying a phase dither and adjusting the amplitude until effects of the dither are minimized.

Patent CA-2141898-A1 (CA)
Title: Rule based parametric design apparatus and method
Inventor: SMITH RANDALL W
IPC: G06T17/00
Filed: 1995-02-06
Abstract: The present invention provides for a rule based parametric design apparatus and method.  The apparatus utilizes one or more predetermined designs including draw primitives and/or other objects.  Designs for the draw primitives are preferably created by artists who refine and distill the designs into a set of rules, with the rules residing in a computer program.  This allows the original, or "parent" design, to be automatically adapted to differently shaped and sized windows and window groupings, while the shapes of the grouping change as units are added to the overall design, the unity of the overall art work is maintained.          A computer, with associated memory to store the various data tables, implements the algorithms and program constraints associated with the present invention.

Patent CA-2144495-A1 (CA)
Title: Strand displacement amplification using thermophilic enzymes
Inventor: FRAISER MELINDA S
IPC: C12Q1/6844
Filed: 1995-03-13
Abstract: Strand Displacement Amplification methods (thermophilic SDA) which can be performed over a broad temperature range (37°C to 70°C). The preferred temperature range for thermophilic SDA is 50°C to 70°C. It has been found that certain thermophilic restriction endonucleases are capable of nicking the hemimodified restriction endonuclease recognition/cleavage site as required by SDA and dissociating from the site.  It has further been found that certain thermophilic polymerases are capable of extending from the nick while displacing the downstream strand. Thermophilic SDA, because of reaction temperatures higher than previously possible with conventional SDA enzyme systems, has improved specificity and efficiency, reduced nonspecific background amplification, and potentially improved yields of amplification products. In addition, the need to add the enzymes in a separate step after the initial heat denaturation of double stranded targets is eliminated when enzymes capable of tolerating the denaturation temperature are used.

Title: Method and apparatus for non-invasive measurement of blood sugar level
Inventor: KOASHI KATSUE
IPC: A61B5/00
Filed: 1993-08-12
Abstract: Laser light is periodically intensity and wavelength modulated. This light is separated into two optical paths.      One irradiates an examined portion of skin for assessing blood sugar. A first detector detects the intensity of transmitted or reflected light from examined portion, while the intensity of the laser light passing through the second path is detected by a second detector. The ratio of the former intensity to the latter intensity is determined by a logarithmic ratio amplifier. The rate of change in the ratio with respect to the change in wavelength of the wavelength modulation is determined by a lock-in amplifier to obtain a derivative spectral signal of the absorption spectrum of glucose. An arithmetic processor detects the blood sugar in the examined portion from the derivative spectrum.

Title: Zig-Zag Electromagnetic Acoustic Transducer Scan
Inventor: LATIMER PAUL J
IPC: G01N29/24
Filed: 1995-06-06
Abstract: A flaw detection method and arrangement utilizes electromagnetic acoustic transducers (EMATs) which ultrasonically test a material for cracks or flaws. Four EMATs are used in a pitch-catch configuration, i.e. two pairs of EMAT transmitters and receivers. The EMAT transmitters and receivers are arranged such that a first EMAT transmitter is located on the surface diagonally across from a first EMAT receiver and a second EMAT transmitter is located diagonally across from a second EMAT receiver. The first and second EMAT transmitters transmit ultrasonic signals to the first and second EMAT receivers respectively; and these ultrasonic signals are transmitted orthogonal to each other. A pulser/receiver is operatively connected to the first and second EMAT transmitters and the first and second EMAT receivers for inducing the EMAT transmitters to propagate their respective waves. The pulser/receiver also receives the signal transmitted through the material after being received by the first and second EMAT receivers. A power source is operatively connected to the pulser/receiver for powering the arrangement; and a computer or oscillator is operatively connected to the pulser/receiver for recording and displaying the signals.

Title: In-flow coriolis effect mass flowmeter
Inventor: KALOTAY PAUL ZOLTAN
IPC: G01F1/00
Filed: 1994-01-18
Abstract: A mass flowmeter is disclosed having a flow tube inserted within the confines of a conduit containing a material flow. Mass flow information is derived for the material flow within the conduit by generating mass flow information for the material flowing within the smaller flow tube positioned within the conduit and then by adjusting the calculations for the flow tube to represent mass flow information for the conduit. In accordance with a first embodiment of the invention, a pressurized cover is positioned around the flow tube to isolate the exterior surface of the flow tube from the material in the conduit. The space between the exterior of the flow tube and the cover is pressurized to a pressure equal to that of the material in the conduit. Both sides of the flow tube walls are at the same pressure so that a flow tube comprised of thinner and more flexible material may be used. In accordance with a second embodiment of the invention, the cover is not used and the flow tube is inserted directly into the conduit and the exterior walls of the flow tube are in contact with the material within the conduit. This embodiment is advantageous in applications in which the conduit material is of low viscosity. The embodiment with the pressurized cover is ideally suited for use in applications with heavy viscosity material.
