Title: Chemical luminescence-detecting apparatus
Inventor: SAITO YUKIO
IPC: G01N21/76
Filed: 1991-03-13
Granted: 1996-07-09
Abstract: The present invention relates to a chemical luminescence-detecting apparatus in which the intensity of chemical luminescence generated in a photometric cell is detected by means of an optical detector.  The apparatus is provided with a plurality of optical detectors of different sensitivities in the vicinity of the photometric cell and the ratio of outputs from the optical detectors for the same sample concentrations is initially determined by taking measurements from standard sample solutions.  When used for measuring unknown sample solutions, the outputs from low sensitivity optical detectors are multiplied by a factor determined by the previously determined ratio so that the converted output signals from the low sensitivity detectors are made the same as the output signals from the high intensity detectors would be for the same concentrations but for the saturation.  In this way, low sensitivity detectors can be used when the high sensitivity detectors are saturated but the output signals from both low and high sensitivity detectors can be processed and displayed in the same way.

Title: Tension buster
Inventor: RITCHEY MERVYN G
IPC: A61H15/00
Filed: 1991-06-14
Granted: 1994-12-27
Abstract: The Tension Buster is a self-help device where the user fully regulates it's usage.  For functional use the device is attached  (to  a  wall,  doorjamb,  archway  etc.)  or  rested (leaned) against an object  (wall,  chair back,  floor etc.).          The device is utilized in a manner where the user will lean and/or push with varying degrees of force against it.  The Tension Buster device is used to:  relax tense and/or spastic tissues  (eg.  muscles,  tendons,  ligaments  (fascia  etc.), pressure  point  myofascial  trigger  points,  manipulate  and adjust fixed and/or stiff joint complexes (primarily of the spine), etc.  The choice of probe used, from the variety of probes available, will determine the physiological affects.          The  larger  ball-type  probe  will  result  in  less  tissue pressure than the pointed or roller-type probe when using the same amount of lean, lay or push force.  This allows the user not only to determine the position of contact but also the amount  of  force-pressure  that  the  probe delivers  to  the contact point.

Title: Production of crackers with reduced or no added fat
Inventor: CRAIG STUART ANDREW SHAW
IPC: A21D8/04
Filed: 1991-07-02
Granted: 2003-02-25
Abstract: The added fat or shortening content of baked goods such as fermented and chemically leavened crackers is reduced while retaining: 1) a tender, non-brittle shelf stable texture, and 2) dough machinability. The fat or shortening is replaced by water and an enzyme composition having activities for hydrolyzing non-cellulosic cell wall polysaccharides. The amount of water and the enzymatic treatment are such so as to avoid excessive starch gelatinization which is deleterious to texture.

Title: Method and equipment for maintaining ice-free locks
Inventor: PONTYNEN ESKO
IPC: E02C1/00
Filed: 1992-04-03
Granted: 1999-10-12
Abstract: The method and equipment for keeping locks free of ice utilises the natural energy resources of the waterway itself. Gravity is utilised to conduct warm water from the depths of the upper waterway via a pipe (1) into the lock where it is distributed by a network of pipes punctuated with holes (3) along the lock floor and around the lock gates. Cooled water is discharged through outlets (6) located in the lower lock gates or lock wall just below the level of the upper waterway. Warm water can effectively be brought to the surface by the use of compressed air conducted to the lock floor either through a special network of pipes or through the existing system (3). The piping may be laid on or under the lock floor. Heatloss can be reduced by insulating the sides of the lock and by fitting the lock with a cover the underside of which is coated with a heat-reflecting material. All the necessary equipment for maintaining an ice-free lock can be installed in both already existing and new locks, thus facilitating inland navigation all year round.

Title: Differential pressure control system for variable camshaft timing system
Inventor: BUTTERFIELD ROGER P
IPC: F16D3/10
Filed: 1992-05-20
Granted: 2003-12-02
Abstract: A camshaft (126) has a vane (160) secured to an end thereof for non-oscillating rotation therewith. The camshaft also carries a sprocket (132) which can rotate with the camshaft but which is oscillatable with the camshaft. The vane has opposed lobes (160a, 160b) which are received in opposed recesses (132a, 132b), respectively, of the sprocket. The recesses/have greater circumferential extent than the lobes to permit the vane and sprocket to oscillate with respect to one another, and thereby permit the camshaft to change in phase relative to a crankshaft whose phase relative to the sprocket is fixed by virtue of a chain drive extending therebetween. The camshaft tends to change in reaction to pulses which it experiences during its normal operation, and it is permitted to change only in a given direction, either to advance or retard, by selectively blocking or permitting the flow of hydraulic fluid, preferably engine oil, through the return lines (194, 196) from the recesses by controlling the position of a spool (200) within a valve body (198) of a control valve in response to a signal indicative of an engine operating condition from an engine control unit (208). The spool is selectively positioned within the valve body by controlling hydraulic loads on its opposed end, one end being subjected to full system pressure from the hydraulic source (230), the other end being subject to the action of an hydraulic pressure multiplier (234) which receives fluid from the hydraulic source by way of pulse width modulated solenoid (206) that acts to controllably reduce hydraulic system pressure in response to a signal from an engine control unit (208).      The spool is centered when the hydraulic loads acting on its opposed ends by the action of springs (202, 204) that also act on the opposed ends of the spool.

Abstract: Provided is an improved refrigeration system for pre-cooling natural gas or cooling a mixed refrigerant for natural gas liquefaction in a propane refrigeration process widely used for the liquefaction of natural gas.  The system comprises a plurality of plate-fin heat exchangers preferably arranged in a parallel relationship for passing a propane refrigerant as a vertical flow and pre-cooling natural gas or cooling a mixed refrigerant for liquefying natural gas, and a thermo siphon drum for the propane refrigerant consisting of a horizontally disposed, laterally elongated tank.  Because the passages of the heat exchanger for the natural gas or the mixed refrigerant extend over their entire length in mutually separate relationship, even when the propane refrigerant, the natural gas or the mixed refrigerant is in both gas and liquid phases, a high efficiency of heat transfer can be attained, and the size of the heat exchanger can be reduced.  In particular, from an economic view point, it is preferable if the thermo siphon drum serves also as a flash tank.

Granted: 2001-04-24
Abstract: For correcting measured spectral data of n samples for data due to the measurement process itself, e.g. due to spectral baseline variations and/or water vapor and carbon dioxide present in the atmosphere of the spectrometer used to make the spectral measurements, the spectral data being quantified at f discrete frequencies to produce a matrix X (of dimension f by n) of calibration data; matrix X is orthogonalized with respect to a correction matrix U m of dimension f by m comprising m quantified correction spectra, at the discrete frequencies f, which simulate data arisi ng from the measurement process itself. The correction method is preferably included in a method of estimating unknown property and/or composition data of a sample under consideration, in which the n samples are calibration samples and a predicti ve model is developed interrelating known property and composition data of the calibration samples to their spectral data corrected for the data due to the measurement process itself. Then, the unknown property and/or composition,data of the sample under consideration is estimated from the predictive model on the basis of its measured spectrum.
