Title: A method and apparatus for compressing a wood sample
Inventor: THOMASSEN THOMAS
IPC: B27H1/00
Filed: 1990-08-23
Granted: 1997-03-18
Abstract: A heated wood sample having a water content exceeding 20 percent is compressed axially in the direction of the grain or fibres of the sample in a compression mould. Oppositely directed compressive forces are applied not only to the end surfaces of the sample, for example by means of a hydraulic cylinder, but also to side surface parts of the sample as frictional forces.  The sample may be arranged within a compression chamber which is at least partly defined by longitudinally overlapping side wall parts, which  are  mutually  displaceable  in  the  longitudinal direction of the chamber, and these side wall parts may be pressed into frictional engagement with the sample for example by means of an inflatable bag or an inflatable hose section, and means may be provided for mutually displacing the side wall parts so as to apply frictional compressive forces to the wood sample.  The side wall parts or friction plates may engage with longitudinally spaced sections of the  sample,  if  desired.    However,  if  a  substantially uniform compression along the  length of the sample is desired, the side wall parts are preferably arranged in pairs of oppositely positioned wall parts each of which extends along substantially the total length of the sample. The hydraulic cylinder by means of which compressive forces are  applied  to  the  end  surfaces  of  the  sample,  may simultaneously  displace  one  pair  of  the  oppositely positioned side wall parts longitudinally in relation to the other pair of side wall parts.   The longitudinally compressed wood sample may be bent and shaped much more easily than a corresponding non-compressed sample.

Title: Methods for locating oil or gas deposits employing earth surface temperatures
Inventor: FONS LLOYD C
IPC: G01V9/00
Filed: 1992-10-01
Granted: 2001-01-30
Abstract: A method for predicting the likelihood of encountering oil or gas deposits below a location and determining the areal extent and magnitude (economic value) of such deposit. The earth's surface temperature at selected points within a location is compared to the earth's surface temperature at a plurality of paints in the surrounding geographic area to determine locations having anomalously low surface temperatures which are indicative of the presence of oil or gas deposits. Representative earth surface temperatures for all locations under consideration and reference temperatures in the geographic area are obtained, under similar ambient conditions, at points having similar topography, vegetative cover and surface features for minimizing extraneous factors which affect earth surface temperature, such that the earth surface temperatures may all be compared with each other to determine locations which have low earth surface temperatures, and therefore are more likely to have oil or gas deposits beneath them. The magnitude of the temperature difference between a location having low temperatures and the representative temperature for the geographic area as a whole is indicative of the thickness and area of an oil or gas deposit below the location.

Title: Touch point identification for automatic clutch controller
Inventor: LIU CHIA-HSIANG
IPC: B60W10/11
Filed: 1992-12-16
Granted: 1999-04-13
Abstract: This invention provides automatic and reliable determination of the touch point of a clutch controlled by an automatic clutch actuation controller.  This invention determines the touch point while idling the engine, with the transmission in neutral and an inertial brake applied.          The clutch actuation controller engages the clutch so that the measured transmission input speed matches a reference speed signal preferably between 40% and 60% of the idle speed.    This  reliably  provides  the  degree  of  clutch engagement at a small torque matching the braking torque.          When the transmission input speed is within a predetermined amount of the reference speed signal,  such as 4%, this invention determines the clutch touch point corresponding to the degree of clutch engagement.  This degree of clutch engagement may be a clutch position signal or a clutch pressure signal produced by an existing sensor used in the automatic clutch control.  If no measured clutch engagement signel is available, this degree of clutch engagement may be the clutch engagement signal used to control the degree of clutch engagement.   The touch point  is  set  as the difference between this degree of clutch engagement for the small torque and a clutch touch point offset.

Title: Temperature abnormality detecting structure for fluid pipe
Inventor: AMANO KAZUO
IPC: G01M3/04
Filed: 1993-02-10
Granted: 1999-06-01
Abstract: A temperature abnormality detecting structure for a fluid pipe detects a temperature abnormality location by laying an optical fiber serving as a temperature detecting portion of a Ramam scattering optical fiber distribution type temperature sensor along a fluid pipe.          The fluid pipe is divided into a plurality of sections in the longitudinal direction, independent optical fibers are laid along the fluid pipe in the respective sections.  A portion of the optical fiber laid along one of the adjacent sections is superposed to be laid on a portion of the optical fiber laid along the other of the adjacent sections in the vicinity of each of the respective boundaries of the sections.  Since the portion of the optical fiber laid along the pipe of one of the two adjacent sections is superposed on the portion of another optical fiber laid along the pipe of the other of the adjacent sections, if an abnormal temperature change occurs due to a trouble such as leakage or outflow of the fluid from the pipe in the boundary area, the temperature change peak position, i.e., the abnormality occurrence locations is detected by the two different optical fibers.  Thus, the detecting accuracy is remarkably enhanced as compared with a case wherein the abnormality is detected by only one optical fiber.

Title: Signal routing device
Inventor: JENKINS RICHARD MICHAEL
IPC: G02F1/21
Filed: 1991-12-02
Granted: 2003-04-22
Abstract: A signal routing device (10) incorporates a multimode beamsplitter waveguide (20) connected by a set of parallel relay waveguides (22) to a multimode recombiner waveguide (24). Each relay waveguide (22) contains a respective electro-optic phase shifter (36). Sets of input and output waveguides (18, 28) are connected to the beamsplitter and recombiner waveguides (20, 24) respectively. The input and output waveguides (18, 28) are periodically spaced at off-centre positions across the respective multi-mode waveguide transverse cross-section associated therewith. Radiation in any one of the input waveguides (18) is distributed between the relay waveguides (22) by virtue of modal dispersion in the beamsplitter waveguide (20). The phase shifters (36) apply a set of phase shifts to the distributed radiation. Modal dispersion in the recombiner waveguide (24) results in the phase shifted radiation providing a non-zero input to one or more of the output waveguides (28). Different sets of phase shifts provide for radi-ation in any one of the input waveguides (18) being transferred selectably to any one or more of the output waveguides (28), as required for selectable signal routing.
