Abstract: An insulating unit having low thermal conducting marginal edge portions includes a pair of glass sheets maintained in a fixed spaced relationship by an edge assembly. The edge assembly includes a spacer frame having a moisture impervious adhesive sealant on outer surface of each of the outer legs and base interconnecting the outer legs.  The spacer frame is made by joining sections of spacer stock or bending a continuous section of spacer stock.  The spacer stock has a pair of outer legs joined by the base to provide the spacer stock with a generally U-shaped cross section.  The outer legs are formed e.g. each leg has a pair of members having a hairpin cross section to reduce the degree of torsional twist of the spacer stock and/or spacer frame with the legs preferably only connected by the base having only one thermal conducting path e.g. through the base from one leg to the other leg.  In practice, the spacer frame is used to fabricate the unit by securing a glass sheet to each of the outer legs with the moisture impervious adhesive sealant.

Abstract: Procédé permettant de décanter la dispersion formée dans l'unité de mélange d'un dispositif d'extraction liquide-liquide, de réguler les flux de solution et de créer des solutions pures dans la partie de séparation. Selon ledit procédé, la vitesse d'écoulement de la phase de solution organique est ajustée de manière à être clairement plus élevée que la vitesse d'écoulement de la phase de solution aqueuse, auquel cas, pour prévenir la turbulence de limite de flux provoquée par la différence de vitesse des phases de solution, la couche de dispersion de gouttes d'eau placée entre les solutions à séparer est ajustée de manière à s'étendre jusqu'à l'extrémité d'évacuation de la partie de séparation. Pour décanter les phases de solution, se trouvent à l'extrémité avant de la partie de séparation au moins trois endroits où la dispersion et les solutions déjà décantées sont amenées à s'écouler à travers une barrière à plaques formant une surface transversale restreinte. La première surface transversale restreinte fait tourner le flux introduit dans la partie de séparation de manière à ce qu'il suive la direction longitudinale de la partie de séparation, et la seconde barrière à plaques dans la direction du flux formant une surface transversale restreinte permet à la phase de solution aqueuse décantée de s'écouler librement dans la partie inférieure de la partie de séparation. La présente invention concerne également un appareil d'extraction selon ledit procédé.

Abstract: Compensation for the effects of duty cycle on the output level of an imaging device, and for the effects of periodically varying distance between the output of the imaging device and its target, is accomplished electronically. An exemplary apparatus includes a source of radiation (generally a laser) having an output level that varies both with an input power level and, undesirably, with the duty cycle. The apparatus also includes means for focusing the radiation onto a recording surface, and a power supply for driving the radiation source. In the case of a diode laser, the power supply delivers a variable current, the magnitude of which determines the power output of the laser. The radiation source is operated to produce, on the recording surface, an imagewise pattern of spots, and an adjustment facility alters the output of the power supply to compensate for output-level variations resulting from duty cycle-that is, from the recent pattern of laser activity. In a first embodiment, the invention includes an up-down counter that receives, as input, the same binary image data in serial form that is used to determine the state of the radiation source as it scans over a recording medium (causing actuation of the source only when adjacent to a location on the recording medium that is to be written). The counter increments during clock cycles when the radiation source is active, and decrements during inactive cycles. As a result, the state of the counter generally reflects the recent pattern of radiation-source activity, and its contents are used to address a list of correction values. In a second embodiment, serial image data is applied to a shift register rather than a counter. This provides a more precise record of the pattern of recent activity, and the instantaneous contents of the register are once again used to address a list of correction values. To compensate for the effects eccentric rotation on the output level of an imaging device, a function that inverts or at least counteracts the resulting power variations is applied to the power supply operating the radiation source.

Abstract: An elastomeric compressor mount has a hollow convex cylindrical head portion which must be passed upwardly through a substantially smaller diameter circular opening in a support foot portion of the compressor. To facilitate the passage of the mount head portion through the support foot opening a specially designed clamping tool is provided which has an arcuate support portion and a clamping portion that may be pivoted toward and away from a concave side surface of the support portion. With these two tool portions pivoted toward each other they are inserted downwardly through the compressor foot opening, opened, and then clamped exteriorly onto the mount head portion in a manner deforming it to a generally U-shaped configuration as viewed along the axis of the mount. The deformed mount head portion, and the still clamped together tool portions are then pulled upwardly through the compressor foot opening, the free ends of the deformed, generally U-shaped mount head portion being pushed toward one another by side edge portions of the foot opening as the head portion passes upwardly through the opening.      After the deformed mount head portion is positioned above the top side of the compressor foot, the tool is released to permit the mount head portion to spring back to its original annular configuration and overlie an annular top side surface portion of the compressor foot.
