Title: METHOD FOR THE PRODUCTION OF .alpha.-TETRALONE
Inventor: YAMAUCHI TAKASHI
IPC: C07C45/00
Filed: 1976-07-14
Granted: 1979-11-06
Abstract: METHOD FOR THE PRODUCTION OF .alpha.-TETRALONE            ABSTRACT OF THE DISCLOSURE:         The specification discloses a method of producing .alpha.-tetralone from tetralin substantially without the production of .alpha.-tetralol as a by-product.  .alpha.-Tetralone is used as the raw material for the production of .alpha.-naphthol and the presence of any .alpha.-tetralol results in the contamination of the product by naphthalene.  The method includes oxidizing tetralin in the absence of a catalyst at a temperature in the range of 50-100°C until 25 to 35% by weight of the tetralin is converted to tetralin hydroperoxide.  An inorganic metal salt is then added to the resulting solution at a temperature of 0-90°C to convert the tetralin hydroperoxide to .alpha.-tetralone.

Abstract: VACUUM TUBE GAS TEST APPARATUS   Abstract A cathode ray tube, having a cathode and first, second and third grid electrodes, is biased on to allow an electron current to flow from the cathode to the second grid electrode during a first time period.  A first voltage, which is proportional to a sum of gas plus leakage currents flowing in the third grid electrode circuit during the first time period, is applied to a first terminal of a capacitor having first and second terminals.  The capacitor is charged to the first voltage by momentarily grounding the second terminal.  During a second time period following the first time period, the cathode ray tube is biased off causing cessation of the electron current flow from the cathode to the second grid electrode and of the gas current to the third grid electrode.  A second voltage which is proportional to the leakage current flowing in the third grid electrode circuit during the second time period, is applied to the first terminal of the capacitor.  A high impedance voltage meter measures a third voltage appearing at the second terminal at the capacitor which is proportional to the gas current.

Abstract: ABSTRACT OF THE DISCLOSURE       A phase locked loop signal generator is especially adapted for synthesizing a selectable frequency signal for exciting an HF radio frequency transmitter to transmit over the seven marine telegraph bands.  The signal generator in-cludes an oscillator for providing a highly stable frequency standard.  Another signal generator is responsive to the frequency standard and to frequency selector signals input by the operator for generating an exciter signal which is coupled to the transmitter for effecting the RF transmission within a predetermined frequency range.  The exciter signal generator includes:  a reference dividing circuit programmable in response to the frequency selector signals for providing a reference frequency signal having a frequency which is a fractional part of that of the frequency standard; a phase locked loop circuit having a frequency divider in the feed-back loop which is responsive to the reference frequency signal for producing an intermediate signal having a frequency which is a multiple of that of the reference frequency signal; and an output divider circuit is coupled to the phase locked loop circuit and is responsive to the frequency selector signal for generating the exciter signal to be at a frequency which is a fractional value of that of the intermediate signal. By varying the frequency selector signal, over 5000 transmit-ting frequencies are available using a conventional harmonic-related transmitter.

Abstract: ASSAYS UTILIZING LOCALIZED ELECTROMAGNETIC RADIATION SOURCES                    Abstract of the Disclosure Chemical species including biological materials such as enzymes, substrates, antibodies, antigens and the like, are determined in very small quantities (down to picomole ranges) through the use of electromagnetic radiation generating reactions such as those catalyzed by light emitting enzyme systems of the bacterial luciferase and fire-fly luciferase types.  The sensitivity of the detection systems is increased by concentrating and localizing at least one component of the electromagnetic radiation generating reaction onto a solid support material.  The component may thus be immobilized and solubilized.  The localized, immobilized component is generally contacted with suitable reactants in a liquid environment in order to produce the electromagnetic signals in a localized area of the reaction environment, i.e., on the support material.  The signals are thereby intensified and detected on suitable instrumentation. The electromagnetic radiation generating systems may also be coupled with other reactions that yield a necessary component of said systems, whereby chemical species associated with the coupled reactions may also be determined.

Abstract: ABSTRACT OF THE DISCLOSURE:          An electrical resistance-roll seam welding machine having a pair of welding rolls or rollers and at least one elec-trode wire which is guided from a supply station for the infeed of fresh welding wire by means of at least one of the welding rolls to a collecting station or location for used or consumed wire.          The electrode wire can be brought into contact by means of the welding rolls with the workpiece which is to be welded.  A brake device is arranged between the supply station and the welding rolls and a tension device for the electrode wire is disposed between the welding rolls and the collecting station or location.  The sum of the tension force exerted by the tension device upon the wire and the brake force exerted by the brake device upon the wire is great enough in order to continuously maintain in tensioned sta-te the electrode wire through its path of travel between the brake device and the tension device.  At least one of the welding rolls is operatively coupled with a drive device which imparts to the electrode wire which is guided by means of said one welding roll a speed of travel coinciding with the desired feed speed of the workpieces during the formation of the welding seam.  The differen-ce between the tension force exerted by the tension device upon the wire and the brake force exerted by the brake device upon the wire is smaller than the entrainment force exerted by the periphe-ry of said one welding roll upon the electrode wire.

Abstract: FIXATION OF RADIOACTIVE MATERIALS IN A GLASS MATRIX                ABSTRACT OF THE DISCLOSURE      This invention relates to radioactive materials which are fixed, stored, entrapped, encapsulated, or other-wise rendered immobile in a glass matrix for extremely long periods of time.  Radioactive material such as radio-active wastes are incorporated into a glass matrix by a process of "molecular stuffing" a porous glass either with a radioactive gas which is trapped in the porous glass by dissolution during sintering of the pores of the glass, or with a salt solution containing radioactive material such as CSNO3, Sr(NO3), etc., or with a combination of both salt solution and radioactive gas, followed by drying and  sin-tering of the pores of the glass whereby these radioactive materials upon chemical change to their oxides, excepting of course the noble gases which remain in molecular form, become a part of the integrated glass structure.       The resulting glass article may have the radioactive material dispersed essentially homogeneously throughout the glass article, or there may be a layer free of such radio-active waste material over the entire surface of the glass article.  In either case such glass articles demonstrate an extremely slow diffusion of the encapsulated radioactive material to the surrounding area.
