Abstract: The apparatus and method are improvements over the refuse derived fuel (RDF) handling system disclosed in Applicant's U.S. Patent No. 4,774,893, in which the activated bins (42) are equipped with centerless baffles (320, 322, 324, 326, 328, 330) made up of a plural­ity of stub type internal baffles affixed cantilever fashion to the bin side walls (60) at predetermined levels downwardly of the bin (42), with the baffles (320, 322, 324, 326, 328, 330) having increased length as the levels of same approach the bin discharge outlet (65), that avoid the formation of vertical bridges building up from the top baffle (320) through the bin inlet to clog end feed of the RDF to the respective bins (42), the use of cycle type operation or pulsing for the vibrating feeder drives on start up of the system to eliminate vertical bridging up from the feeder trough into and through the activated bins supplying same and insure the steady low feed rate required while the power plant furnaces involved are brought up to temperate, and to provide the system vibrating feeders with an inclined ramp type obstruction upstream but adjacent the feeder trough RDF discharge outlet to the furnace fuel feed chute serviced by same to insure that the RDF supplied to the furnace feed chute was conveyed solely by vibration, whereby the tendency of some furnace fire chambers to operate at negative pressure, which can result in the loss of control of the discharge rate of the feeder servicing same, is not a factor in the supply of the RDF to the furnace fire chamber.

Abstract: A linear bearing or bushing is provided in which "loaded" and "unloaded" or return ball channels are formed directly in the thickness of the shell or body of the bearing or bushing without the use of an initially separate ball guidance cage. Curved transfer channels 4 are formed in end caps of the bearing or bushing so as to interconnect the ends of pairs of the "loaded" and "unloaded" ball channels and each channel preferably has a conformity radius which is substantially 1.06 x the radius of each bearing ball which, in use, will be movably disposed therein. The ball channels are produced, during the formation of the bearing or bushing, by the use of a ball end or ball nose slot mill.

Abstract: The principles of nonimaging optics, rather than imaging optics, are used to provide an asymmetrical flux extraction cup for an LED illumination lamp that has an asymmetrical limited viewing angle or cutoff angle. The cup has a flat section (6) in the bottom normal to the optical axis (4), for attachment of the LED (3). In a cross section of one side of the cup, there is a circular section (7) extending from the flat section (6) to a lower point (17) located at an intersection with a line from the opposite cup lip (18) through a nearest edge point (F1) of a top surface of an envelope (14) in which the LED (3) is positioned. Next is a lower parabolic section (8) extending from the lower point (17) to an upper point (19) located at an intersection with a projection of the top surface of the positioning envelope (14). The lower parabolic section (8) has a vertex at the lower point (17), an axis projecting through the nearest edge point (F1) and the lower point (17), and a focus (F1) at the nearest edge point (F1). Then there is an upper parabolic section (9) extending from the upper point (19) to the cup lip (21). The upper parabolic section has a vertex at the cup lip (21), an axis extending through the farthest edge point (F2) and parallel to the axis of the lower parabolic section (8), and a focus (F2) located at the farthest edge point (F2) of the top surface of the positioning envelope (14).

Abstract: A checkpointing mechanism implemented in a data processing system comprising a dual processor configuration gives the system a fault tolerance capability while minimizing the complexity of both the software and the hardware. 
     The active and backup processors are coupled asynchronously with some hardware assist functions comprising a memory change detector which captures the memory changes in the memory of the active processor and a mirroring control circuit which causes the memory changes when committed by establish recovery point signals generated by the active processor to be dumped into the memory of the back up processor so that the backup processor can resume the operations of the active processor from the last established recovery point. 
     The active and backup processors may each be connected to a dedicated memory and recovery point storing means, or to a memory including two dual sides shared by all the processors for storing data structures and recovery points.

Abstract: PCT No. PCT/NO89/00126 Sec. 371 Date Jun. 7, 1991 Sec. 102(e) Date Jun. 7, 1991 PCT Filed Dec. 7, 1989 PCT Pub. No. WO90/06288 PCT Pub. Date Jun. 14, 1990.Contaminated water is caused to flow up through a chamber while aerated to produce air bubbles of a size mainly in the range of 0.03 mm to 1 mm by means of air diffusors disposed at the bottom of the chamber. Organic and inorganic impurities in the water is, by a combination of water flow, flotation and physical adsorption caused by the air bubbles, brought to the surface of the water in the chamber, where a foam containing dissolved impurities is formed and instantly removed from the chamber while a mixture of water particles and microscopic air bubbles is allowed to flow over a partition wall into an adjacent basin having a considerably larger volume than that of the chamber. In the basin a flotation process will take place causing a slurry to form on the surface of the water in the basin, which is removed, preferably at the end of the basin opposite the chamber. The rising air bubbles from the diffusor in the chamber causes the water to circulate through the chamber and basin, the chamber and basin communicating above and below the partition wall. Preferably a biofilter medium having upwardly extending, intercrossing channels is disposed in the chamber.

Abstract: On a mis au point un vidéoscope cervical (V) simple mais particulièrement utile, utilisable par un médecin pour examiner le col de l'utérus afin de déterminer la présence de lésions cancéreuses ou d'autres anomalies. De plus, du fait de la petite taille de la caméra, il y a suffisamment d'espace entre ladite caméra et les cuillers du speculum (S) pour insèrer des forceps ainsi que d'autres instruments qu'il peut être nécessaire d'utiliser. L'utilisation du vidéoscope cervical (V) conjointement avec un monochromateur permet au médecin d'échelonner la longueur d'onde de lumière d'un bout à l'autre du spectre de lumière jusqu'à ce qu'il observe une fluorescence identifiant des cellules anormales. Il peut ensuite détruire lesdites cellules à l'aide d'un faisceau laser. Lorsqu'il n'observe plus de fluorescence, il peut alors interrompre le fonctionnement du laser, sachant que la lésion a été totalement erradiquée. On peut également prévoir un canal (70) destiné à excercer une aspiration afin d'éliminer la fumée créée par la destruction de la lésion. Enfin la caméra est réglable le long d'un guide (3) situé sur la cuiller fixe (10) du speculum (S0 afin de le focaliser.

Abstract: An apparatus and process for iso-thermally sealing electronic packages with a thermosetting adhesive have first and second platens for holding and for heating a package and a lid, respectively. The second platen is operatively coupled to the first platen, so that alignment of the package to the lid is automatically achieved when the first platen and the second platen are placed in a sealing position. The process includes the steps of pre-heating a package and a lid, the lid having a mating surface coated with a thermosetting adhesive; and mating together the heated package and the heated lid when iso-thermal conditions are achieved. The iso-thermal seal process and apparatus are based on the principle of uniting the package and the lid with a thermosetting adhesive after all three components, and gases in the cavity as well, are already at a stable adhesive curing temperature.

Abstract: Lead inclusion in copper-containing wrought alloys is coming into disfavor due to health and environmental considerations. Machinability, as well as retention of workability properties, associated with lead inclusion are assured by bismuth together with a modifying element, phosphorus, indium or tin. The modifying element minimizes the workability-precluding embrittlement otherwise caused by bismuth. The alloys are essentially of a stoichiometry and content of prototypical lead-containing alloy as specified as CDA 100-700 series wrought alloys in the 8th edition of the CDA Handbook of Wrought Products except that lead is replaced by bismuth within the weight percent range of 0.5-2 and that such composition invariably contains at least one of the third element additions in the weight percent ranges indicated; 0.1-0.5 P, 0.25-1.0 In, 0.5-6.0 Sn.
