Patent CA-2081296-C (CA)
Title: Failsafe limit switch with automatic reset for rolling fire doors
Inventor: HSIEH TSUNG WEN
IPC: E06B9/88
Filed: 1992-10-23
Granted: 1997-12-30
Abstract: A failsafe limit switch with automatic reset for a rolling fire door is usable together with a rolling door with a brake.          There is a movable plunger between a secured position and a triggered position which compresses a spring as it moves from its triggered position to its secured position. A movable catch between the engaged position and the released position holds the plunger in the secured position when the catch is in the engaged position under the impetus of the spring when the catch is in the released position. When the catch is in the released position, it also closes the contacts of a normally open switch; and if the catch is in the engaged  position, it allows the contacts of the switch to open. The switch is wired in series with a solenoid; the movable arm of the solenoid acts to move the plunger from the triggered position to the secured position when the solenoid is energized. A collar constrained against rotation is threadably mounted on a shaft,  the linear position of the collar with respect to the catch is a function of the angular position of the shaft. For a specific angular rotation of the shaft, the collar contacts and releases the catch.

Une cartouche de rechange (195) emmagasine des données propres à un patient/utilisateur. Les appareils d'analyse (170) sont précis et se prêtent facilement à l'exécution de dosages du glucose à la maison. Le brevet divulgue également une méthode pour un calibrage facile et fiable pour chaque individu des appareils d'analyse quantitative, notamment l'obtention de plusieurs échantillons de sang et de mesures du glucose dans le sang à un intervalle prédéterminé. Ces valeurs sont entrées dans l'appareil. Des mesures optiques par rayonnement infrarouge proche de chaque individu sont prises simultanément à un autre intervalle prédéterminé au moyen de l'appareil d'analyse. On effectue une analyse de régression du calibrage sur les données afin de calibrer l'appareil d'analyse pour chaque individu, ce qui comprend l'interpolation linéaire des mesures du glucose dans les échantillons de sang avec les enregistrements optiques du rayonnement à infrarouge proche.

Abstract: The invention is directed to a method for producing wheat flour from newly harve sted wheat grain. The grain direct from harvest is treated with moisture to increase the moisture content of the endospe rms to a level at least about 4 to 5 wt-% greater than the original level, thereby producing hydrated wheat grain. The hydrated wh eat grain is then rapidly dried to a moisture content approximating the original level of the newly harvested wheat grain to p roduce grain that can be efficiently milled. The milling of the treated grain produces a wheat flour that is more acceptable and desirabl e for baking than that produced from newly harvested wheat that is not processed according to the invention. The rapid conv ersion of grain from the newly harvested state to a more millable state is shown by an increase in the capacity of the milled flou r to rapidly hydrate. Newly harvested grain normally increases its hydration capacity over the first two to three months after its ha rvest. The method of the present invention permits elimination of this aging process yet produces a flour having desirable baking c haracteristics.

Abstract: A sawmill that is a compact integrated unit of a multiplicity of components mounted on a common frame for performing different functions to produce pieces of lumber from a log. Logs can be processed that have a minimum diameter of approximately 2" and a minimum length of approximately 42" with the overall length of the mill being approximately 17'. There are a number of power driven feed and guide rolls that propel a log endwise along a fixed path. The processing components include first and second pairs of chipper canter units with novel chipper heads, a pair of rabbet units in which each has a pair of cutter heads on concentric telescopic shafts and power driven rolls for off-feeding pieces of lumber of differing widths. The log feed speed and/or chipper head speed can be varied to provide chips of selected different lengths.          Positioning of the processing units is controlled by a programmed processor unit. The cut pattern and selective use of the edger is dictated by log geometry provided by scanning.

Abstract: A low cost analog arcing detector and a circuit breaker incorporating such a detector provide a variable response time to arcing faults based upon the amplitude of the arcing current. A filter generates pulses having an amplitude proportional to the amplitude of the step increase in current generated by the striking of the arc. The pulses are rectified and the amount by which the single polarity pulses exceed a threshold value, selected to eliminate nuisance trips on current step increases characteristic of some common loads, is integrated by a capacitor connected to a resistor which continually adjusts the capacitor voltage in a sense opposite to that of the pulses. The capacitor and resistor are selected to generate a trip signal as a function of the accumulated, time attenuated magnitude of the step increases in current associated with each striking of the arc current. Preferably, the pulses are squared before the reference current is subtracted to provide faster response for large amplitude arc currents, while avoiding false trips caused by known loads. Preferably, the arcing detector is used with a ground current detector which provides further protection by tripping on ground currents flowing through carbon tracks deposited by arcing currents below the threshold of the arcing fault detector.
