Patent ZA-846752-B (ZA)
Title: Self-pumping hydrodynamic bearing
Inventor: FUST ARMIN
IPC: F16C33/10
Filed: 1984-08-29
Abstract: In hydrodynamic bearings it is necessary for the lubricant leaving the lubricant film to be cooled. The self-sufficient, reliable operation of the system is only ensured if the transport of lubricant can be generated and maintained by the bearing itself. For this purpose the lubricant is taken from the contact surface of the moving component (2) into a pumping gap (13), recessed in the stationary component (4), which exhibits a strong constriction (17) in the direction of movement by a graduation (16). This pumping gap (13) may be machined directly in the contact surface of a bearing segment or in a separate component. A part of the lubricant stream which enters the pumping gap (13) is removed in front of the constriction (17) through an appropriate lubricant discharge duct (14). This branched lubricant stream (19) represents the delivery quantity of the pumping gap (13). The remainder of the branched lubricant stream flows on through the lubrication gap (18). The pumping pressure corresponds to the pressure built up hydrodynamically in the pumping gap (13).

Title: Threaded coupling
IPC: E21B17/042
Filed: 1987-07-08
Abstract: The present invention refers to a threaded coupling for percussion drill rods having a diameter of 30 - 40 mm, comprising an external rod thread and an internal sleeve thread, the longitudinal section of said threads having continuously curved tops and bottoms. In threads of the type mentioned above it is desirable to be able to tighten them to a relatively high degree because otherwise the thread coupling loosenes when used in hydraulic percussive drilling machines of a high frequency. Significant for the thread coupling of the present invention is that the pitch (S) is 7 - 11 mm, the radii of curvature (R1 - R4), at least for the portions of the tops and bottoms located immediately adjacent the contact shoulder, are 3 - 5 mmm, and that the threads have a height (H1,H2) of 1.2 - 1.6 mm.

Title: A method of using ion exchange media to increase taxane yields.
Inventor: CARVER DAVID
IPC: C07D305/14
Filed: 1993-11-26
Abstract: The present invention is a method that uses an absorption column for the cleavage and recovery of taxanes, which are not normally detected as free taxanes. The method processes a first solution that contains standard detectable taxanes and other undetectable taxane compounds to generate a second solution that contains a higher percentage of detectable standard taxane then the first solution. The first step of this method is loading a column having a first opening and a second opening with an ion exchange media. The next step is placing the first solution in the first opening of the column so that the first solution passes through the ion exchange media in the column and flows to the second opening. Thus, the taxane compounds are converted to standard taxanes by an ion exchange reaction and the second solution is formed. Then the next step is collecting, from the second opening of the column, the second solution and recovering from the second solution a larger percentage of standard taxanes then was detectable in the first solution. The ion exchange media of the present solution is an ion exchange resin. The ion exchange resin can be a mixture of an anion exchange resin and a cation exchange resin. The anion exchange resin is in the OH-form. The cation exchange resin is in the H+ form. Preferably, the ion exchange resin is alumina.

Title: Open end spinning device has fibres fed to rotor - from opening roll in a current of air which is adjustable to control waste removal
IPC: D01H/

Granted: 1979-01-30
Abstract: A sliver is fed to a toothed opening roller mounted within a housing whereby the sliver is opened into discrete on the periphery of the opening roller and the fibres are fed through a fed duct into a spinning rotor to be spun into yarn. A current of air to fed the fibres is set up in the feed duct, pref. by applying a suction through an exhaust duct to a chamber in which the rotor is mounted and the strength of this current of air is controllable. Trash separated from the sliver passes on the periphery of the opening roller is not attracted into the feed duct by the current of air but passes on the opening roller to a trash removal duct positioned downstream (in the sense of rotation of the opening roller) of the feed duct. The air flow can be adjusted to control trash removal and prevent trash from entering the feed duct.
