Abstract: ABSTRACT OF THE DISCLOSURE       A reproducing objective lens for videodiscs for which the working distance is large, the flatness of field is high, resolving power is high and further, the objective lens is so corrected as to compensate for aberrations introduced by addi-tional elements fixed in the optical path and occurring in the long conjugate of the objective lens.  For the objective lens, according to the present invention, the Gauss-type lens con-figuration is adopted as it is easier to obtain a large working distance and high flatness of field with the Gauss-type lens configuration.  The objective lens for videodiscs, according to the present invention, is a modified Gauss-type lens system comprising five single lenses, i.e., a first, second, third, fourth and fifth lens.  The first lens is a positive lens with its planar surface positioned toward the object side, the second lens is a positive lens, the third lens is a negative meniscus lens with its convex surface positioned toward the ob-ject side, the fourth lens is a negative meniscus lens with its concave surface positioned toward the object side and the fifth lens is a positive meniscus lens with its concave surface positioned toward the object side.  Further, the objective lens for videodiscs of the present invention satisfies the following conditions when reference symbol f represents the focal length of the lens system as a whole.  Reference symbol f3 represents the focal length of the third lens. Reference symbol f4 represents the focal length of the fourth lens.  Reference symbol r6 represents the radius of curvature of the surface on the image side of the third lens.  Reference symbol r7 re-presents the radius of curvature of the surface on the object side of the fourth lens.  Reference symbol d represents the thickness of the first lens and reference symbol d5 represents the thickness of the third lens. 1. 0.30 .DELTA. r6/f ? 0.23 2. 0.25 ? d1/f ? 0.l5 3. 1.4 ? r6 ¦r7¦? 0.9 4. 6.0 ? f3¦/¦ f4 ? 2.5 5. 0.31 ? d5/f ? 0.21

Abstract: Abstract of the Disclosure An air-driven dental scaler (10) is disclosed having water transport means associated with the tool assembly for delivering water to a scaling type work tool (26). The water transport means comprises a tube (134) disposed within a hollow connector body (20) and extending between a water plenum (108) at one end of the connector body (20) to the other end of the connector body, whereat the scaling type work tool (26) is attached.   The water transport tube (134) has an internal diameter of greater than 0.010 inch and a surface roughness smoother than 25 micro-inches to minimize clogging of the tube by mineral deposits or sediment.  The independent fluid path permits the use of hard, martensitic stainless steels for the work tool (26) and softer, corrosion-resisting austenitic stainless steels for the water transport tube (134).  The water transport means delivers a controlled quantity of water to the work tool (26) and the water is atomized by the vibratory movement of the tool (2.6).

Abstract: ABSTRACT OF THE DISCLOSURE         A device for primary separation of valuable ore material from gravel or other waste in placer mining prior to sluicing.  The separator comprises a frame having sides and front and back ends and adapted to be inclined at an angle to the horizontal during operation.  A material entrance is provided at the elevated end.  A screen comprising a plurality of hinged rigid plates, laterally extending across the frame, extends from side to side and front to back of the frame and is supported within the frame.  The end of the screen at the elevated end of the separator is secured to the frame.          The plates are spaced from adjacent plates a pre-determined distance.          Screen distortion means comprising a plurality of spaced rows of rounded projections are mounted on the carriage.  These projections bear against the bottom surface of the screen whereby, during operation, they move with the carriage back and forth beneath the hinged plates to create a wave action on the screen to move material across the screen from front to back.  Water spray means is secured to the frame to spray from overhead onto material on the screen to assist passage of valuable ore and other material through the spaces between the plates into a receptacle beneath the screen and screen distortion means.  Since only smaller material ultimately is collected and passed to the sluice box using a separator according to the present invention, relatively little water is needed for the sluicing part of the recovery of valuable ore.

Abstract: Précis Il est connu que le colmatage des fuites de pétrole des puits sous basse ou haute pression,se fait à l'aide de bouchons qui s'adaptent sur les puits qui sont fabriqués selon les méthodes conventionnelles. La réalisation de ces procédés a montré que l'étanchéité n'est jamais réalisée avec efficacité surtout quand il règne une haute pression dans le puits ou quand des fissures causées au puits laissent échapper du pétrole par l'extérieur. Dans la présente invention,le bouchon est fait de manière à ce que la partie inférieure rentre dans le puits et y est fixée à l'aide du collet fabriqué sur son extrémité qui a la même forme et les mêmes dimensions que le chambrage usiné à l'intérieur du puits. Cette même partie comporte encore des vérins hydrauliques qui servent à faire l'étanchéité entre le bouchon et le puits. De même, la partie supérieure comporte les vannes principales qui servent à la fermeture du puits et, sur cette partie, une grande cloche à extrémités extensibles pourra être fixée dans le but de récupérer les fuites externes.

Abstract: TWO LEVEL CONSTANT VOLTAGE FLOAT CHARGE RECTIFIER AND BATTERY SURVEILLANCE APPARATUS A two level, constant voltage float charge rectifier and battery surveillance apparatus is taught, having full-time battery and circuit operation surveillance. An electrical load and a battery are connected to the apparatus, in parallel, whereby the apparatus generally provides DC power directly to the load and maintains the battery on constant voltage float charge. In the event of an AC outage, the load is maintained from the battery. The apparatus automatically initiates a battery re-charging and equalization program if an AC outage is longer than a predetermined period, or in the event of deep discharge of the battery, or after a predetermined period of time (usually 30 days) since the last re-charging and equalization program. Constant surveillance includes an indication of the operation of the apparatus, including indication of low battery voltage, indication of a general failure alarm such as by failure of major components of the apparatus, and an indication at all times as to whether the apparatus is operating on a constant voltage float charge program or a battery re-charging and equalization program at a voltage level higher than the float charge level.
