Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to sucker rods and pony rods for use in a well.  Conventional sucker or pony rods are formed from a single length of rod the ends of which are upset forged, machined, heat treated and cold rolled in order to provide a respective coupling at each end of the rod.  The present invention provides many advantages compared with the conventional sucker rods by fabricating the sucker rod from discrete components which are friction forged together.  The sucker rod is formed of an elgonate central member having a respective coupling component friction forged to each end thereof.  The couplings may comprise a male com-ponent and a female component.  The coupling components are each provided with a shank which can be held in the chuck of a friction forging device.  The shanks are shaped so as to enable raised lettering to be provided on the shank without the lettering degrading the alignment of the component in the chuck.  The central member may be formed from a different material to the coupling components.

Abstract: ABSTRACT OF THE DISCLOSURE    New Camptothecin derivatives possessing high anti-tumor activity with slight toxicity, represented by the general formula:       wherein R1 stands for a hydrogen atom, an alkyl group, a hydroxyl group, an alkoxy group or an acyloxy group, R2 for a hydrogen atom, an alkyl group, an aralkyl group, a hydroxymethyl group, a carboxymethyl group or an acyloxymethyl group, and R3 for the grouping -XR' (where R' is a hydrogen atom, an alkyl group or an acyl group and X is an oxygen atom or a sulfur atom), a nitro group, an amino group, an alkylamino group, an acylamino group or a halogen atom, with the proviso that when both of R1 and R2 are hydrogen atoms, R3 should not be hydroxyl group, methoxy group or acetoxy group.  These new camptothecin derivatives are prepared by treating a 5-R1-7-R2-camptothecin derivative with a peroxidant and then reacting the resultant 5-R1-7-R2-camptothe-cin-1-oxide with an active hydrogen compound under irradiation of UV-rays or by catalytically hydrogenating the ring B of camptothecin in a solvent, treating the resultant tetrahydro product with an acylating agent, introducing nitro group into 10-position of the acylated product by the reaction with nitric acid, splitting off the acyl group in the 10-nitro product by hydrolysis and treating the hydrolyzed tetrahydro product with an oxidizing agent for dehydrogenation, and if desired, reducing the nitro group in the resultant product to amino group and modifying the amino group by N-alkylation, N-acylation or by diazotization followed by hydrolysis or Sandmeyer reaction, before or after the oxidation of the 10-nitro-tetrahydro product.     - 1a -

Abstract: ABSTRACT OF THE DISCLOSURE     A process for the simultaneous catalytic hydrogenation of coal and a petroleum-derived  slurrying oil to produce predominantly  hydrocarbon  liquid  products,  employing  an ebullated bed catalytic hydrogenation reaction step.  In the process, particulate coal is admixed with the slurrying oil comprising from about 5% to 100% by weight catalytic cracker aromatic  decant  oil  boiling  in  the  range  of  about 300-1000 F.  The coal-oil slurry is reacted with hydrogen in an ebullated bed of particulate hydrogenation catalyst to effect substantial conversion of the coal and the slurrying oil  component  to  produce  a  range  of  liquid  products including an increased percentage of C4-650°F boiling range fraction  product.    In  an  alternate  embodiment  of  the process,  the oil  feed includes an increased percentage of petroleum-derived decant oil and heavy coal-derived recycled oil  from  the product  liquids.    If desired,  some of  the C4-400°F naphtha product  fraction can be returned to the petroleum refinery catalytic cracker to produce additional gasoline product.

Abstract: METHOD OF DETECTING CURRENT GEODYNAMIC                MOVEMENTS IN MASSIF                Abstract of the Disclosure In a surface layer of a massif or in a control medium brought in contact with the massif an electromagnetic field is established 7 and series of amplitudes of said field magnetic component or series of other values are periodically measured, which values are values of the func-tions of at least one electromagnetic parameter of the medium being irradiated. The measurements are made in a circle of up to 5 m radius with a centre in a profile point, whereafter the results of measurements made in diff-erent times are compared and the current geodynamic movem-ents are evaluated from the variation of a qualitative characteristic of an azimuth anisotropy of the electromag-netic parameter of the medium being irradiated. From the nature of the variations of said. characteristic there is determined a type of rock deformation associated with the current geodynamic movements, and from the speed of these variations there is determined the intensity of the current geodynamic movements.

Abstract: Abstract of the Disclosure The disclosure teaches an improvement in a free turbine type engine which comprises a power limit unit.          The unit includes a first sensor for measuring pressure at the turbine inlet, and a second sensor for measuring temperature at the turbine inlet.  A third means provides a measurement indicative of turbine exhaust pressure and may be a sensor located in the exhaust duct which is downstream of the turbine or may comprise means for pro-viding outside ambient pressure readily available from existing aircraft instrumentation, e.g., altimeter.          A processor means calculates shaft horse power (SHP) from the above measurements.  Other means are provided for generating a reference signal, and the reference signal is compared with SHP.  When SHP is greater than the reference signal, then fuel to the engine is controlled to reduce engine power.  The unit can also be adapted for calculating torque, and for reducing the torque when the torque is greater than the reference level.          The invention also relates to a method for limiting power or torque using the above apparatus.
