Abstract: ABSTRACT OF THE DISCLOSURE A circuit for monitoring the capacitor battery of a filter circuit connected to a transmission line, the capacitor battery consisting of at least two parallel legs, each with a number of series-connected capacitors. A first signal is produced which corresponds to the total alternating cur-rent flowing through the capacitor battery.  A second signal is produced which corresponds to the difference between the currents flowing through the respective parallel legs of the capacitor battery.  The current dif-ference signal is compared with a respective fraction of the total current signal.  A fault indicator signal is produced if the difference between the difference current signal and the fractional total current signal exceeds a predetermined threshold value.  Further circuitry is provided for correct-ing drift in the difference current signal, which may be caused by tempera-ture variations or acceptable capacitor failures.  Automatic ranging cir-cuitry may be provided in embodiments of the invention in which the total capacitor battery current varies in amplitude over a large range.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to processes for inserting DNA into eucaryotic cells, particularly DNA which includes a gene or genes coding for desired proteinaceous materials for which no selective criteria exist.  The insertion of such DNA molecules is accomplished by cotransforming eucaryotic cells with such DNA together with a second DNA which corresponds to a gene coding for a selectable marker.         This invention also concerns processes for producing proteinaceous materials such as insulin, interferon protein, growth hormone and the like which involve cotransforming eucaryotic cells with DNA which codes for these proteinaceous materials, growing the cotrans-formed cells for production of the proteinaceous material and recovering the proteinaceous material so produced.         The invention further relates to processes for inserting into eucaryotic cells a multiplicity of DNA molecules which includes genes coding for desired proteinaceous materials.  The insertion of multiple copies of desired genes is accomplished by cotransformation with the desired genes and with amplifiable genes for a dominant selectable marker in the presence of successively higher amounts of an inhibitor.  Alternatively, the insertion of multiple copies of desired genes is accomplished by transformation using DNA molecules formed by ligating a DNA molecule including the desired gene to a DNA molecule which includes an amplifiable gene coding for a dominant selectable phanotype such as a gene associated with resistance to a drug in the presence of successively higher amounts of an agent such as a drug against which the gene confers resistance so that only those eucaryotic cells into which multiple copies of the amplifiable gene have been inserted survives.  Eucaryotic cells into which multiple copies of the amplifiable gene have been inserted additionally include multiple copies of the desired gene and may be used to produce multiple copies of proteinaceous molecules.  In this way otherwise rare proteinaceous materials may be obtained in higher concentrations than are obtainable using conventional techniques.

Abstract: REFRACTORY METAL RECOVERY PROCESS     Abstract of the Disclosure Disclosed is a process for recovering chromium, vana-dium, molybdenum, and tungsten from secondary resources such as alloy scrap comprising a refractory metal and base metals such as cobalt, nickel, iron, and copper. The scrap is calcined with sodium carbonate in air to convert the refractory metal values to Mo04=, VO4?, W04=, and Cr04= and the base metals to water insol-uble oxides.  A leach of the calcined materials produces a pregnant liquor rich in refractory metals which, after separation of the vanadium, molybdenum and tungsten values, is treated with C0, CHOO-, CH30H, or HCHO to reduce Cr+6 to Cr+3.  The carbonate and bicarbonate salts produced as a byproduct of the reduction are recycled to the calcination stage.     As a result of the V, W, and Mo partition, a mixed solid comprising Ca0?nV205, CaMo04, and CaW04 is produced.  This is treated with carbonated water or formic acid to selectively dissolve vanadium values which are subsequently recovered by pre-cipitation or extraction.  The remaining mixed CaW04 and CaMo04 solid is treated with H202 and sulfuric acid to reject a Mo and W-free CaS04 precipitate, and to produce a concentrated solution of tungsten and molybdenum.  The W values are selec-tively precipitated from this solution by decomposing the peroxy complexes.  The process has the advantages that a wide variety of different feed materials can be treated, no energy intensive pyrometallurgy is involved, reagent consumption is minimized, and no aqueous effluents are produced.

Abstract: ABSTRACT OF THE DISCLOSURE      A self-cleaning reflective road marker comprises a housing formed of a generally cylindrical portion insertable into the road and a flanged portion for lying on the road surface connected thereto.  The housing contains a stud mounted on a rubber hemisphere.  The stud contains a circular reflector and the housing contains a circular o-ring located in the flanged portion opposite the reflector. In response to the passing of a tyre over the marker, the stud is depressed and the reflector is wiped clean by the o-ring.  On removal of the tyre force, the resilience of the rubber hemisphere forces the stud into its original position and the reflector is further cleaned by the o-ring.       The stud consists of two parts connected together, from above by a threaded bolt such that when the marker is fixed in the road the part can be removed to enable removal or replacement of the reflector and the o-ring.

Abstract: Abstract A pressure responsive switching device, particularly a pressostat or thermostat, comprises an actuating element (5) which is loaded in one direction by an operating element (1) at the pressure and in the other direction by a main spring (9) by way of a force transmission device (10). The latter has a physical quantity (Pk) which is variable with the force transmitted by the operating element. In addition, there is a measured value generator (23) which, depending on this physical quantity, delivers an electric analogue signal (S). The force transmission device may comprise a compensating force producer (10) in the form of an expansion element (15) which is provided with a liquid-vapour filling and a heating device (21), by which the compensating force of the force of the operating element (1) is made to follow. In this way, the switching device can deliver an analogue signal (3) corresponding to the system pressure (P) by using the same operating element (1).     Fig. 1.
