Abstract: ABSTRACT OF THE DISCLOSURE         A device is taught for controlling the residual charge on a thyristor switched capacitor.  A capacitor is in series circuit relationship with at least two pairs of back-to-back thyristor switches which is then connected across an AC network.  Each back-to-back thyristor combi-nation is shunted by a non-linear clamping device which exhibits a very high resistance below a specified voltage level and a very low resistance above that voltage level.          A pulse stretcher and a  sequential  firing circuit ar-rangement is utilized so as to prolong the conduction of one of the back to-back pair of thyristor switches at a time.  During an overvoltage condition in the AC network the non-linear clamping device will  limit the  residual charge on the capacitor.  A plurality of capacitor, thy-ristor switch, non-linear clamping device combinations may be utilized in parallel with the AC network.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to latices of sulfonated thermoplastic polymers which function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits and lift cuttings from the holes in the drilling operation for oil and gas wells.   The sulfonated thermoplastic polymer of the latex has 5 to 100 meq. of sulfonate groups per 100 grams of the sulfonated thermoplastic polymer, wherein the sulfonated groups are neutralized with a metallic cation or an amine or ammonium counterion.   A polar cosolvent can optionally be added to the mixture of oil drilling mud and sulfonated polymer, wherein the polar cosolvent increases the solubility of the sulfonated polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sul-fonated polymer.

Abstract: Abstract Improvements in or relating to coupled cavity travelling wave tubes A millimetre coupled cavity travelling wave tube has its slow wave structures formed by a hobbing process.  In a preferred construction, each slow wave structure is made of two individual halves each extending for the length of the structure.  Each half contains one half of each cavity and one half of each beam hole and all of the portions of cavity and portions of beam hole in each half are formed in one hobbing operation.  Coupling holes between cavities are formed where required by a process (e.g. spark erosion) separate from hobbing and if ferrules or drift tubes are required to extend out of the cavity separating walls in the finished tube, the beam coupling holes are made oversized and individual ferrules are brazed into position.  The two halves of the slow wave structure are united by furnace brazing.

Abstract: ABSTRACT OF THE DISCLOSURE        Inspection of a fusion splice between the ends of two optical fibres,  the splice being re-inforced by a support member, is facilitated.  In particular, inspection of the joint between the optical fibre cores in a fusion splice is facilita-ted.  The splice is held in a transparent support member by means of a transparent adhesive matched in refractive index to the cladding of the fibre. Apparatus is described which allows the splice to be viewed in two directions at right angles by means of a microscope whose position may be adjust-ed therefor without rotation relative to the support member.  The arrangement is of particular relevance to splices between monomode fibres whose small core diameters call for a high degree of precision in jointing in order to avoid optical loss.

The KBS of the present invention is useful as a potent tumoricidal or anti-tumor agent.     TITLE OF THE INVENTION      Human endogenous cancer regulatory factor, process for preparing the same, pharmaceutical composition containing the same and human monocytic leukemia cell lines FIELD OF THE INVENTION    The present invention relates to a novel human endogenous cancer regulatory factor, a process for preparing the same, a pharmaceutical composition containing the same, and human monocytic leukemia cell lines.                   BACKGROUND OF THE INVENTION    While several biologically active materials are known to have anti-tumor activities, interferons and tumor necrosis factor (TNF) are most popular. The latter is a proteinic, biologically active material produced by animals, and it is said that unlike interferons, TNF has trans-species potent tumoricidal or anti-tumor activities.          Furthermore, the TNY is believed to act on tumor cells both directly and indirectly through the mechanism of immunization  in the host.    TNF was first discovered in mice by Old et a1. in 1975 at Sloan-Kettering Institute for Cancer Research, U.S.A., and it was later reported by Carswell et al. as a material capable of causing tumor necrosis [Proc. Nat. Acad. Sci.          USA, 72, No. 9, pp. 3666-3670 (1975)].          Methods of purifying TNFS (i.e. mouse TNF and rabbit TNF)

Abstract: Apparatus is disclosed for tempering curved glass sheets suspended in a vertical orientation. The apparatus comprises a pair of opposed manifolds each having a plurality of nozzles and positional adjustment means to optimize the heat exchange effect between the tempering station and the sheet of glass. A first adjustment means adjusts the orientation of the manifold with respect to the surface of the glass by means of four independently adjustable screw jacks that mount the manifold on a frame. A second adjustment means adjusts the horizontal spacing between the manifold and the surface of the glass by means of four screw jacks that operate in unison. In addition, another displacement means permits the manifold to be displaced from its tempering position to facilitate the insertion and removal of the glass sheets between the two manifolds. Advantageously, the displacement means is mounted on the second adjustment means.

Abstract: ABSTRACT          A barrel section for a lightweight firearm such as a recoilless gun which is subjected to extremely high transient internal pressures and temperatures on firing is formed from an epoxy-resin impregnated carbon fibre material.  The material, in the form of an elongated tow is wound on a mandrel, cured and then removed from the mandrel for subsequent operations such as machining and assembly.  During manufacture, a gas-erosion preventing layer is formed on the mandrel and a plurality of layers of tow are helically-wound thereon at a helix angle .theta. = tan-1           where .sigma. axial and .sigma. hoop are the   axial and hoop stresses produced in the barrel section by axial and hoop loads respectively.  Lightweight recoilless guns using barrels in accordance with the invention are lighter and less costly to fabricate than conventional guns and are capable of firing upwards of 30 rounds before excessive erosion causes the firearm to be unusable. This is in comparison to a capability of firing only 5 to 10 rounds before failure for conventional guns.  Failure is usually the result of the high pressures and temperatures encountered during firing, upwards of 9,000 p.s.i. and 3,000 °K.
