Title: Multifunction occupancy sensor
Inventor: BALDWIN JOHN R
IPC: G01K1/16
Filed: 1997-10-17
Granted: 2005-03-22
Abstract: A multifunction passive infrared occupancy sensor which functions as an occupancy sensor for security systems and also as an occupancy sensor for energy management control systems. The occupancy sensor comprises at least one segmented infrared lens array wherein the segments of the infrared lens array establish different optical lobes in the field of view of the occupancy sensor. At least one pyroelectric infrared detector is positioned at or near the focal point of the segmented infrared lens array, for detecting movement of infrared sources within the field of view of the occupancy sensor and producing an output signal representative thereof. A processing means analyzes the output signal of the detector for security detection purposes by detecting changes in the output signal greater than a given security threshold. The processing means also analyzes the output signal of the detector for energy management purposes by detecting changes in the output signal greater than a given energy management threshold, which is less than the security threshold. In one embodiment first and second processing circuits detect changes in the detector output signal greater than the security threshold and energy management threshold.      In a second embodiment the output of the detector is coupled to an analog to digital converter, the output of which is coupled to a digital processor which utilizes one of two different software processing routines, a security threshold processing routine, and an energy management threshold processing routine. A further embodiment electronically switches detector elements in a detector element array.

Abstract: Cette invention se rapporte à un système et à un procédé permettant d'alimenter en matière fibreuse fragmentée, du type copeaux de bois, la partie supérieure d'une cuve de traitement, du type lessiveur en continu (11). Ledit procédé renforce la simplicité, l'exploitabilité et la maintenabilité d'une telle alimentation grâce à la suppression du dispositif de transfert à haute pression utilisé traditionnellement dans les installations conformes à l'état antérieur de la technique. Au lieu d'utiliser un dispositif de transfert à haute pression, on utilise une ou plusieurs pompes à boue (251, 251I), situées au moins 30 pieds en dessous de la partie supérieure de la cuve de traitement, pour mettre sous pression les copeaux cuits à la vapeur et réduits en boue, et ce à une pression supérieure ou égale à 10 bars. Une conduite de retour (235), qui prend naissance en partie supérieure du lessiveur, peut éventuellement être fonctionnellement reliée à une ou plusieurs pompes, et dans le cas où elle se trouve reliée à ces pompes, la pression dans ladite conduite de retour peut être réduite au moyen d'un détendeur (58) et/ou d'un réservoir de détente (253). La vapeur provenant du réservoir de détente peut servir à cuire à la vapeur les copeaux. On peut prévenir la décompression en disposant des robinets d'isolement (65-69) dans les conduites reliées à la partie supérieure de la cuve de traitement, commandés par une unité de commande (69) qui est sensible à la pression détectée dans la conduite de boue conduisant à la partie supérieure de la cuve de traitement.

Abstract: Emulsified powders are prepared by emulsifying an oil-soluble substance, a chemically modified starch and, if desired, a vegetable gum in water. The emulsified powders obtained according to this process show less disintegration of emulsified particles caused by compressing impact, which leads to less oil exudation. The tableted product of the emulsified powders of the oil-soluble substance is easy in handling, weighing, ingesting and others and thus can be utilized over a wide range of technical fields such as foods and drinks, medicaments or the like.

Abstract: This invention relates to a process for the preparation of polyurethane encapsulated fertilizer particles. This process comprises applying an isocyanate-reactive component to fertilizer particles, and applying an aliphatic polyisocyanate to fertilizer particles in separate ste ps to form polyurethane encapsulated fertilizer particles. The two reactants may be applied in either order, with the polyisocyanate being first or last. These two steps may optionally be repeated as many times as necessary to yield polyurethane encapsulated fertilizer particles which contain from 0.5 to 15% by weight of polyurethane, based on the total weight of the encapsulated fertilizer particles. It is also possible to mix the isocyanate - reactive component and the polyisocyanate together to form a mixture which is then applied to the fertilizer particles. These polyurethane coatings which encapsulates the fertilizer particles are biodegradable.</SDO AB>

Title: High-efficiency air-conditioning system with high-volume air distribution
Inventor: KOPKO WILLIAM L
IPC: F24F13/072
Filed: 1998-05-15
Granted: 2006-12-19
Abstract: A system and method for providing conditioned air to the interior space of a building includes separate dehumidification and sensible cooling functions. The separate dehumidification allows for much higher supply air temperatures, preferably within about 10 °F to about 15 °F of the air temperature of the building space. Low-velocity air distribution through a ceiling plenum or a vent into the space allows for very low fan static pressures, which greatly reduces fan energy usage compared to conventional ducted systems. The low static pressures and high supply-air temperatures allow the use of existing drop ceiling construction with little modification. Optional return air channels between an inner glazing and an outer glazing of exterior windows can virtually eliminate heating loads at the building perimeter, which virtually eliminates the need for simultaneous heating and cooling. The result is a major improvement in energy efficiency and comfort while reducing installed cost of the system.
