Patent CA-2212277-A1 (CA)
Inventor: BERGMANN THORALD
IPC: H01J49/16
Filed: 1997-09-10
Abstract: In order to facilitate a mass spectrometric analysis of the content of surfaces, it is necessary to bring the analyte molecules into the gas phase. This is done with a tightly focused, preferably pulsed laser beam. This laser beam is focused onto the surface with a mirror that is placed as close as possible to the analysed surface. In order to achieve a very small focal point, deflection and focusing of the laser beam is done with a single optical element. The evaporated material passes through a opening in the mirror into the mass spectrometer. It is also possible to let the evaporated material pass right next to the mirror into the mass spectrometer. Preferably this invention is combined with a time-of-flight mass-spectrometer by placing it behind the ion optics, as viewed in the direction of acceleration of the time-of-flight mass-spectrometer.

Title: Temperature and passive infrared sensor module
Inventor: ECKEL DAVID P
IPC: G08B13/19
Filed: 1997-08-12
Abstract: A temperature and passive infrared sensor module comprising a sensor module housing having air flow vents therein in top and bottom or side surfaces to allow air to circulate through the sensor module housing.  A temperature sensor is mounted in the sensor module housing in a position which is open to air circulating through the sensor module housing.  A passive infrared sensor is also mounted in the sensor module housing in a manner in which it is not exposed to air circulating through the sensor module housing, such that it is not adversely affected thereby.  In one embodiment, a foam block is positioned around to encase and isolate the passive infrared detector.  In several embodiments, the passive infrared sensor and temperature sensor are mounted on opposite sides of the printed circuit board such that air circulates around the temperature sensor only on one side of the printed circuit board.  In other embodiments, the passive infrared sensor and temperature are positioned on the same side of a printed circuit board, and a partition is positioned therebetween to prevent air circulating around the temperature sensor from reaching and circulating around the passive infrared sensor.  In several embodiments, at least one air duct is provided extending between the air flow vents and the temperature sensor to channel the flow of air from the air flow vents to the temperature sensor but not to the passive infrared sensor.

Abstract: An improved pneumatic tool for the removal and application  of  tire  cross  chains  configured  having  a manually actuated valve connected at its inlet port to a compressed air source and at its outlet port to a pneumatic diaphragm motor for actuation of a diaphragm.  The control valve includes an air bleed port which allows air to escape through the valve when the trigger or other operating means is released deactivating the valve.  This feature allows an almost immediate recovery of the jaws to the open position. The pneumatic tool for the removal and application of tire cross chains also includes a fixed jaw support assembly having a base plate for attachment to the face of the pneumatic diaphragm motor, the fixed jaw support assembly having a pair of upright members attached to the base plate and  extending  perpendicularly  and  in  spaced  apart relationship to one another to accommodate the attachment of the fixed and the moveable jaws between the two upright members thereto.   This feature eliminates torque between the jaw assemblies and the pneumatic diaphragm motor when pressure is applied to the jaws.

Inventor: EPSTEIN ARTHUR J
IPC: H05B33/20
Filed: 1996-03-12
Abstract: Light-emitting bipolar devices (10) consist of a light emitter (15) formed from an electroluminescent organic light-emitting material in contact with an insulating material. The light emitter (15) is in contact with two electrodes (12, 18) that are maintained in spaced-apart relation with each other. The light emitter (15) can be formed as an integral mixture of light-emitting materials and insulating materials or as separate layers of light-emitting and insulating materials. The devices operate with AC voltage (24) of less than twenty-four volts and in some instances at less than five volts. Under AC  driving, the devices produce modulated light output that can be frequency or amplitude modulated. Under DC driving, the devices operate in both forward and reverse bias.

IPC: B61F5/22
Filed: 1998-02-20
Abstract: A process and a device for the control and/or regulation of a wagon body tilt system (1) for a railed vehicle, e.g., a train. Limit values with respect to comfort are taken into consideration for this purpose. In an equivalent way, these limit values preset a comfort scale for a rail camber or tilt (.PHI.c) as desired tilt values (.PHI.desired, .PHI.des. speed, .PHI.des.  accel.) for the control and/or regulation of a wagon body (2) as relevant value based on the system limits and permit a subsequent regulation within the adjustment system (4) of the wagon body (2) only within these limits. If at least one limit value for comfort and/or parameters describing the system is exceeded, these desired tilt values (.PHI. desired, .PHI. des.speed, .PHI. des.accel.) are then adapted by taking into account this at least one exceeded limit value and are converted to adapted desired tilt values (.PHI.' desired, .PHI.' des. speed, .PHI.' des. accel.) and used to adjust the wagon body tilt systems (1). The device for implementing the process consists of a desired value adapter (11), including a simulated tilt system (7), a tilt condition limiter (8), and an inverse, simulated tilt system (10), as well as a tolerance presetting unit (9), which can be a component of the desired tilt value adapter (11). The limit values as well as parameters describing the system used to determine the adapted desired tilt values (.PHI.' desired, .PHI.' des.speed, .PHI.' des. accel.) are stored in the tolerance presetting unit (9). This desired tilt value adaptation makes it possible to avoid hitherto existing disadvantages in the control and/or regulation, e.g. lowered driving comfort, damage or early wear and tear of the tilt system.

Title: Hybrid active vibration control method and device, particularly for mechanical and acoustic vibration and the like
Inventor: CARME CHRISTIAN
IPC: G10K11/178
Filed: 1996-09-27
Abstract: A filtering device consisting of a nonadaptive feedback filter that generates active attenuation of the vibration on the framework, without generating instability in a first frequency band, and an adaptive feedforward filter is disclosed. Feedforward filtering coefficients are adapted in real time according to an algorithm chosen to minimize the energy of the types of vibration which are picked up by a sensing device as a function of the energy of the types of vibration which are picked up by the sensing device, and of the previously measured transfer function, in the presence of a feedback filtering device and in the absence of a feedforward filtering device, between an actuator device and a first sensing device. The device makes it possible to linearize the feedback attenuation throughout a second frequency band which is wider than the first frequency band, to accelerate the convergence of the minimization algorithm and to enhance the robustness of the feedforward filter.

Abstract: A composite storage tank is built which has double wall characteristics. A method of building the tank comprises the steps of applying a viscous resinous care material to a support surface and then winding onto, into or along with the viscous resinous core material discrete filament bundles. The resinous core material encapsulates the filament bundles, but does not significantly penetrate into an interior of the bundles. The substantially resin-free interiors provide flow paths for the ready detection of wall leakage. The resultant composite storage tank has double wall characteristics. A crack or hole in either an inside or outside surface which extends at least to the encapsulated filament bundle interiors wall alert the tank's operator/owner to a leakage problem.
