Title: Fluorescence analyzer for lignin
Inventor: BERTHOLD JOHN W
IPC: G01N21/64
Filed: 1992-09-14
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for measuring lignin concentration in a  sample of wood pulp or black liquor comprises a light emitting arrangement for emitting an excitation light through optical fiber bundles into a probe which has a sensing end facing the sample.  The excitation light causes the lignin concentration to produce fluorescent emission light which is then conveyed through the probe to analyzing equipment which measures the intensity of the emission light.  Measures are taken to maximize the emission light intensity which is due to lignin concentration and distinguish it from background and interfering light.  The fluorescent light intensity is found to drop off in a predictable manner with increased lignin concentration.
Patent CA-2079293-A1 (CA)
Inventor: HAMER STEVEN M
IPC: H04B10/508
Filed: 1992-09-28
Abstract: An optical data communication system for transmitting a stream of light pulses, including both priority pulses and variable data pulses from an optical emitter atop certain vehicles, such as police cars, etc., to a detector mounted along a traffic route. The method allows variable data to be transmitted in a stream of light pulses along with priority pulses. The variable data can include an identification code that uniquely identifies the emitter, an offset code that causes a phase selector to create a traffic signal offset, an operation code that causes traffic signal lights to assume at least one phase, and a range setting code that causes a phase selector to set a threshold to which future optical transmissions will be compared. Phase selectors separately identify received priority and data pulses and assemble data derived therefrom. The data may include a discrimination algorithm for tracking a plurality of optical transmissions with each detector channel. The optical emitters may also be provided with a coincidence avoidance mechanism which causes overlapping optical transmission from separate optical emitters to drift apart. The optical signal format allows variable data to be transmitted while maintaining compatibility with prior optical traffic preemption systems.

Patent CA-2088095-A1 (CA)
Inventor: DANDLIKER RENE
IPC: G01L1/24
Filed: 1993-01-26
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention discloses a method and an apparatus which enables one to obtain definite non-modulo-2.pi.-dependent measurements wherein a method for the fiber-optic measurement of force, which is based upon the strain-induced birefringence of a single-mode light waveguide, provides a compensation method for the phase differences of two linear modes of the exiting light waves, which are caused by the force acting on the light waveguide and the consequent change in birefringence.  In one embodiment of the method, a liquid crystal cell, the birefringence effect of which can be controlled electrically, is used as a compensation element.  The maximum of an autocorrelation function, which occurs as an image, and the respective voltage at the liquid crystal cell, are evaluated as a measurement for the birefringence which is to be compensated for and, accordingly, for the effective force.  In an alternate embodiment of the method, the two partial waves are directed transversely relative to the propagation direction of the wave fronts by an optical component with linearly space-dependent birefringence.  The auto-correlation function can then be obtained as a spatial coordinate and can be plotted electronically by a line detector such as a line array.  The location of the maximum of the autocorrelation function is, under certain defined conditions, a measurement for the birefringence which is caused in the light waveguide by mechanical tension from which the magnitude of the force, which acts on the force sensor, can be calculated.

Title: Post extrasystolic potentiation stimulation with physiologic sensor feedback
Inventor: BENNETT TOM D
IPC: A61N1/362
Filed: 1992-06-10
Abstract: A Post-Extrasystolic Potentiation (PESP) cardiac pacing energy stimulator for applying paired and/or triggered pacing stimulation pulses to the right atrium and/or ventricle incorporating one or more sensors, such as a venous oxygen saturation, ventricular, atrial, or arterial blood pressure, or intracardiac or systemic blood flow sensor, and signal processing circuitry for controlling the frequency of or number of heart cycles between periodic delivery of triggered or paired pacing to induce PESP for the treatment of congestive heart failure or other cardiac dysfunctions.  Preferably, a first sensor, e.g., a ventricular or arterial blood pressure or flow sensor, is employed to monitor the performance of the heart, and develop a cardiac performance index (CPI) and a second sensor, e.g., an oxygen saturation sensor positioned in the coronary sinus, is employed to monitor cardiac muscle stress and develop a cardiac stress index (CSI) to balance performance and stress. The PESP stimulator may be incorporated into a dual chamber (DDD) pacing system with or without physiologic rate control and with or without backup cardioversion/defibrillation therapy capabilities or in a separate, single purpose device. The PESP  stimulator has particular application in atrial stimulation for augmenting filling of the ventricles.

Title: Gas-pouring and extracting device
Inventor: LUFT VILEM
IPC: F04F10/00
Filed: 1993-04-19
Abstract: ABSTRACT                  Page two of three.             This device consists of three parts, made of corrosive resistant plastic or metal.  The primary use of this device is to enable safe transfer of flammable liquids to and from vehicle gas tanks.  It differs from conventional spouts due to its length, flexibility and versatility.  Conventional spouts are too short to reach properly and are easily damaged during pouring.  This can lead to rather dangerous situations, resulting in risk of fire or explosion.  Not mention the unnecessary pollution and waste.  This invention almost completely eliminates all these hazardous possibilities.  This device also has some unusually handy features, making it rather unique.  It can be used "hands free", but with supervision, eliminating spills caused by fatigue, when you have to hold a heavy container, for an extended period.  The spout is flexible and long enough to safely pour and siphon, without effort. Since it totally eliminates the need of sucking up the liquids using mouth, it is a very safe form of siphoning.

Abstract: An apparatus for laminating a layer of polymer plastic film (52, 60) - such as non-oriented polyurethane or polyvinyl butyral laminated with oriented polyethylene terephthalate - to glass (18, 54), is taught. A saddle (12) is provided having essentially the same contour as the glass (18) that contacts it during the lamination process; and at least the surface of the saddle has an essentially identical coefficient of heat expansion and contraction as the glass (18) so that there is no significant slippage of the glass with respect to the saddle as the glass and polymer plastic film are heated and cooled. A segmented saddle may be provided having segments (44) with substantially different coefficient of heat expansion and contraction than that of glass, but by being spatially isolated there is no gross expansion or contraction of the saddle face compared with that of the glass. A compression ram (14) presses against the polymer film to be laminated to the glass.  Either or both of the saddle and the ram is heated (24), usually the saddle. The ram may have a flexible hard face (32) and an extendible piston (34) which operates against it to ensure initial contact of the ram and film to the glass at the centre of the glass; and as the ram continues to press against the film, the extendible piston (34) is withdrawn for complete area contact. Methods of operating the apparatus are taught; and the invention contemplates multi-laminar glass/plastic structures.
