Abstract: TONE SOURCE FOR TELEPHONE SYSTEMS          Abstract of the Disclosure A tone source is automatically adaptable in operation to generate tones as required for virtually any TDM telephone system in accordance with stored tone samples being defined to meet the requirements of a particular one of the telephone systems.  The tone source provides encoded tone samples from a ROM wherein each tone sequence is stored at corresponding sequential address locations.  Each sequence is terminated at unique first and last address locations.  The last address location is followed by an address location having an end-of-tone code stored therein.          A sample of each of the tones is progressively fetched from the ROM in response to each frame occurrence in an associated operating telephone facility.  The first address of each sequence is stored at a corresponding index address location in the ROM.  In response to each end-of-tone occurrence the index address of the instant tone sample is read from the ROM and used as a starting point for subsequent fetches.  Shortly after power-up, the tone source inherently converges into an orderly cyclic operation of providing tones as defined in the ROM.                               -i-

Abstract: ABSTRACT OF THE DISCLOSURE      A hanger means having a pair of spaced apart raised portions such that, upon connection of the hanger means with a suspension system isolator means, these raised portions restrict motion of the hanger means relative to the isolator means by being spaced apart by a distance approximately equal to the width of that passageway.  These two raised portions are formed by coining one end of the hanger means so as to form, as a first raised portion, a lip and upsetting another portion of the hanger means, spaced apart from that lip, to form an annular collar, as a second raised portion.

Abstract: Abstract of the Disclosure A working material used in a magnetic refrigerator radiates heat when it is magnetized and absorbs heat when it is demagnetized.  The working material is cylindrical and extends vertically.  A heat pipe has a cylindrical internal space directly surrounding the peripheral surface of the working material and con-taining helium gas as a heat medium.  The peripheral surface of the working material in contact with the internal space functions as a condensing surface of the heat pipe.  A superconductive coil surrounds the working material and intermittently applies a magnetic field thereto.  A refrigerator unit supplies a cooling space with helium gas at 20°K or below.  The helium gas from the refrigerator unit removes heat produced from the working material when it is adiabatically magnetized by the coil.  When the working material is adiabatically demagnetized, it rapidly absorbs heat to cool the helium gas in the internal space of the heat pipe.  The helium gas condenses on the peripheral surface of the working material, and falls in drops into the internal space to be stored at the lower end portion thereof.  Thus, heat is transferred in one direction or upward in the heat pipe.

Abstract: ABSTRACT: A method and a system for monitoring a sea area.     The invention relates to a method and a system for monitoring a water area with regards to presence and localization of unknown objects, which transmit sound, in particular submarines. According to the invention three or more listening devices (A1, A2, A3) are thrown out in an area, where indication about an unknown object has been obtained. The listening devices are provided with hydrophones and radio transmitters for transmission of received sound by modulation on a carrier. The devices cooperate with stationary radio stations (M1, M2, M3), where the sound waves are demodulated. Time correlation between the sound waves from an object received by three selected listening devices gives information about the position of the object relative to these selected listen-ing devices. If the position of the listening devices is unknown, for example if the devices are floating free, this position can be determined by comparing the mutual time position for a particular radio signal transmitted from each listening device when received in three statio-nary radio stations with known positions. The listening devices may suitably also be provided with receivers for receiving radio control signals, for example relating to order for activation, selection of radio channel, etc.

Abstract: ABSTRACT OF THE DISCLOSURE          The known nuclear hydroxylation of phenol with organic solvents of hydrogen peroxide in the presence of a catalyst is carried out with special, practically anhydrous solutions of hydro-gen peroxide in solvents forming azeotropes with water, said azeo-tropes having a boiling point below that of hydrogen peroxide, and also with sulphur dioxide as the catalyst.  Therefore, the nuclear hydroxylation can be carried out in a much simpler manner than heretofore.  Difficult separations, for example, of water-phenol, or the separation and recovery of the catalyst are dispensed with.          Furthermore, the yields are increased.

Abstract: ABSTRACT OF THE DISCLOSURE         The coating of hollow bodies open on one side, such as cans, with paints such as clear or pigmented lacquers, enamels or the like give rise to difficulties for a continuous one-step operation.  In the coating process, the cans are first washed, when coated inside and outside, dired and optionally printed and again dried.  The difficulties of a continuous one-step operation, are solved by utilizing an electro-dipcoating bath and by employing a process wherein the cans are immersed in the electro-dipcoating bath vertically and with the closed bottom downward into the bath, filled from the top with the bath liquid and during the raising from the bath, tilted so that their opening is pointing downward.  The cans may also be forcibly immersed with their opening below the surface of the bath for filling with the bath liquid by means of a filler device. Uniform coatings of a plurality of hollow bodies in a continuous one-step coating process are thereby achieved.
