Abstract: HAZARDOUS VOLTAGE PROTECTION CIRCUIT     Abstract of the Disclosure A circuit for protecting telephone lines from AC hazardous voltages.  The circuit includes an amplitude dis-criminator triggered at a predetermined voltage level con-nected to the telephone lines, and providing an output pulse for each zero voltage crossover of the hazardous voltage.  A digital pulse counter counts a predetermined number of output pulses from the amplitude discriminator, which in turn oper-ates a switch after the predetermined number of pulses are counted, opening the telephone lines between the central office and the telephone instrument until the hazardous voltage has been removed from the lines.

Abstract: "Therapeutic  method for the treatment  of juvenile diabetes mellitus and pharmaceutical composition  for such a method".                 ABSTRACT OF THE DISCLOSURES      The oral or parenteral administration of L-carnitine or certain L-acyl carnitines, typically L-propionyl carnitine, or the pharmacological salts thereof, permits a considerable reduction  (from 20 to approx. 50%) of the daily dose of insulin that should be administered to patients affected by juvenile diabetes mellitus to restore normal blood glucose levels.    Moreover, L-carnitine and such acyl carnitines actively inhibit ketoacidosis, thus avoiding the risk of ketoacidosic coma in such patients.

Abstract: ABSTRACT     A method is described for diagnosing for the presence of a specific disease, a specific stage of a disease, or an allergy in a patient.  Differentiated antigenic components of a larger protein or poly-saccharide group are supported in spaced relation on a solid-state substrate.  At least a subset of the components is known to be reactive with antibodies present in serum obtained from a patient having the specific disease, a specific stage of a disease, or an allergy.  Upon exposure to the patient's serum, antigen-antibody reactions on the substrate are detected for correspondence with a known pattern specific for the disease, the specific stage of the disease, or the allergy.  Also described is a method for producing such a diagnostic antibody probe and the probe itself.

Abstract: KEY TELEPHONE HOLD ARRANGEMENT            Abstract of the Disclosure There is disclosed a line circuit for establishing a hold condition on a communication line, extending between a switching machine and a key telephone station, during an open switching interval when no current flows on the communication line.  The control signal required to enable the hold circuit is arranged to be time dependent.  For a fixed time interval, which bridges the OSI period, after the telephone station answers a ringing line a hold condition is enabled exclusively by a control signal on the A-lead from the station.  This time dependent hold enable arrangement permits a hold capability during an OSI condition.  After this time interval elapses a hold condition is enabled by a joint signal condition on the A-lead and a current continuity condition on the communication line.

Abstract: DETECTION OF CHEMICAL MUTAGENS IN MARKER RESCUE ASSAY    ABSTRACT OF THE DISCLOSURE     The present application discloses a short-term microbial assay useful in detecting chemical mutagens.  A          Bacillus subtilis which is infected with a strain of the tem-perate bacteriophage ?105 having a conditional lethal mutation is specifically illustrated.  In the assay exogenous DNA from wild-type ?105 is reacted with a potential mutagen and then transfected into the B. subtilis carrying a mutated ?105 DNA.          After plating, an increase in the frequency of clear plaques signifies that the test compund is mutagenic.         The present invention provides a short-term muta-genicity test which detects frameshift as well as base substi-tution mutations induced by chemicals.

Abstract: A PROCESS FOR IMPREGNATING ORGANIC FIBERS          Abstract of the Disclosure Organic fibers are impregnated with an aqueous emulsion comprising (1) an organopolysiloxane containing diorganosiloxane units in which both organic radicals are monovalent hydrocarbon radicals, and further contains at least two monovalent SiC-bonded organic radicals with a basic nitrogen atom per molecule in which the SiC-bonded organic radicals with a basic nitrogen are present in monoorganosiloxane units, (2) an organopoly-siloxane having at least 3 Si-bonded hydrogen atoms per molecule, (3) a catalyst for the condensation of Si-bonded condensable groups (4) emulsifiers, and (5) a diorganopolysiloxane containing an Si-bonded hydroxyl group in each of its terminal units and whose radicals are free of the basic nitrogen atom.  If it is desired to impart hydrophobic properties to the impregnated organic fibers, then it is essential that (6) a trimethylsiloxy end-blocked diorganopolysiloxane be added to the aqueous emulsion.          Moreover, as the amount of trimethylsiloxy end-blocked diorgano-polysiloxane (6) is increased in the emulsion, the hydrophobic properties of the impregnated fibers increases.         When the aqueous emulsion is applied to keratin, especially wool, it prevents or reduces shrinkage due to felting, particularly when the keratin has been pretreated with chlorine, rinsed and neutralized.
