Abstract: Universal Joint Structure with Improved Seal Abstract An improved seal for use in a universal joint structure.  The seal includes a C-shaped seal ring which is loaded into sealing engagement with an associated bearing cap by a load ring compressively nested within the C-shaped seal ring.  The leg of the seal ring sealingly engages the bearing cap under a controlled load to provide an improved oil seal.  The arrangement of the seal is co-ordinated with the allowable play of the trunnions of the joint structure so as to assure positive sealing engage-ment of the seal ring as a result of the loading of the load ring over the entire range of play movement per-mitted in the joint structure.  The trunnions may be journaled in the bearing caps by suitable roller bearings which may effectively further limit the play so as to limit sliding movement as well as axial deflection of the seal rings for further improved sealing in the joint structure.  In one form the leg of the seal ring sealingly engaging the bearing cap has an effective sealing engage-ment therewith of approximately one-half the radial extent of the leg.

Abstract: 9960      Abstract Process for the in-situ leaching of uranium from a subterranean ore deposit employing a lixiviant containing a carbonate leaching agent and an oxidizing agent.  The lixiviant is heated to a temperature of at least 110° F. prior to injection into the subterranean ore deposit.  The use of a heated lixiviant provides for a substantially greater ultimate uranium recovery than that attained through the use of a lixiviant injected at ambient temperature conditions.  The process may be carried out in several stages.  In the first stage, a relatively low temperature lixiviant is injected. This is followed by a second stage in which the lixiviant is heated to an elevated temperature and then injected into the deposit.  The invention is particularly applicable for use in subterranean deposits which contain uranium associated with carbonaceous material.

Abstract: ABSTRACT OF THE DISCLOSURE         A mixer comprising a shaft which is appropriately curved to substantially conform to the interior shape of the sides and bottom walls of a steam kettle and a structure for supporting the shaft within the steam kettle.  The latter consists of a lid which fits about the peripheral upper edge of the steam kettle.  A length of a heat resistant, self-lubricating, tubular material, such as Teflon*, is slidably extended over substantially the entire length of the shaft, to perform a dual function.  This material, first of all, eliminates the need for any type of bearing structure which normally would be required in order for the shaft to be rotated when disposed to extend through the lid, into the steam kettle.  The material itself functions as a bearing. Secondly, the material being heat resistant can seat on the bottom of the steam kettle and thereby permit the shaft to be easily and properly seated in the steam kettle without the need for other mechanical devices.  This material also functions to wipe or scrape the product from the walls of the steam kettle, while preventing the shaft from directly contacting the metal surfaces of the steam kettle, so that the product is constantly or continuously wiped from the walls of the steam kettle and there is no metal-to-metal contact between the shaft and the steam kettle during stirring or mixing.  A stirring blade is attached to the shaft in a fashion such that it is easily removed for cleaning.  The shaft is easily rotated by a handle affixed to its upper terminal end.    * Trade Mark

Abstract: INK DROP COMPENSATION BASED ON             DYNAMIC, PRINT-DATA BLOCKS     Abstract The invention relates to an ink jet printer and in particular to correcting the flight path of drops from the printer to reduce print position error on the print media.  Compensation values can be stored and retrieved for use by the printer to correct the flight of a drop to the print media.  The compensation values are based on the pattern of print data representing the drops in the ink stream with the drop being compensated.  To reduce the number of variables that must be dealt with, one or more portions of the print data can be grouped into one or more blocks and each block treated as having a single effect on the drop being compensated.  However, basing the compen-sation value on one predetermined treatment of print drops as having individual effects or as having individual effects in combination with one or more group effects on the drop being compensated does not produce the optimum print appearance for all combina-tions of print data.  Disclosed herein is a method and apparatus for selecting one of a plurality of treatments of the print data based upon the pattern of print data representing drops in the ink stream.  Depending on the number of drops in the flight path with the drop being compensated, the drops may be treated as each having an individual effect, an individual effect by some drops and a single group effect by the remaining drops or an individual effect by some drops and group effects by multiple groups of the remaining drops.  Also more storage space may be allotted for compensation values based on the combinations treated as multiple groups because these combinations produce the most visible print error.
