Abstract: Abstract The method disclosed by which to prepare fine hexag-onal ferrites for use in magnetic recording, is one which consists basically in dissolving a) carbonates or other soluble compounds of an aikaline earth metal such as strontium or barium, b) a carbonate or other soluble compound of cobalt, and c) titanium trichlor-ide, all in a solution of ferric citrate and water, whereupon a polycondensation is brought about by ad-dition of ethylene clycol, and heat is applied to eliminate water and organic matter from the compound.          Addition of the alkaline earth metal, the cobalt and the titanium is proportioned precisely on the basis of the stoichimetric properties of the end-product, the formula for which is ReO . (6-x)Fe2O3 . xCoO . xTiO2 where x is the extent to which cobalt and titanium atoms replace iron atoms and Re is the alkaline earth metal. Final application of heat produces crystalliz-ation of the superfine hexaferrite particles.

Abstract: Hydrodynamic Retarder Abstract of the Invention The invention relates to a hydrodynamic retarder having two independent operating circuits.  Opposite a double rotor on the one hand is a stator fixed to a housing, and the rows of vanes concerned are inclined. The other half of the rotor forms with a rotatable stator a second operating circuit having rows of blades equally effective in both rotational direct-ion s.  The stator of this second operating circuit can be coupled via a gear unit and a coupling device to the retarder shaft.  The gear unit drives the stator in a direction opposite to the direction of rotation of the rotor and with step-up transmission. When braking from a high travelling speed, only the first operating circuit is effective, the stator of the second operating circuit is released by the re-tarder shaft and freely rotates as well without any braking action.  As the speed drops, the coupling de-vice is actuated and the stator of the second oper-ating circuit is driven in the opposite direction, during which the second operating circuit is tempor-arily emptied.  The advantage of this arrangement is high braking force at high speeds of travel, assoc-iated with high braking force in the low speed range right down to approx. zero and in both directions of travel, also the retarder does not need to be attached to the gear shift and does not need to feed power in by a driving engine.

Abstract: Abstract of the Disclosure DEVICE FOR COIN CHECKING     The coin to be checked for several characteristics influences, partially in succession and partially simulta-neously, the coils (7-12) of several oscillator tank circuits (1-6).  The oscillator tank circuits (1-6) are correspondingly  connected to an amplifier (14) for the formation of an oscillator, individually in succession, those circuits with simultaneously influenced coils being connected periodically in alternation to this amplifier.          Thereby, successive and simultaneous, high-frequency test signals are produced which are nested in one another in accordance with the time-division multiplex principle, these test signals corresponding to the influences exerted by the coin on the oscillator tank circuit coils (7-12).          These test signals, after demodulation (19) and analog-to-digital conversion (20), are compared in an evaluating unit (22) individually with criteria stored in a memory(23) for each type of coin to be accepted.     .1.

Abstract: ABSTRACT OF THE INVENTION     A method and system for controlling the temperature of liquid cooled power transformers.  The winding temperature of a transformer winding is electronically computed from the actual top oil temperature and the incremental additional temperature resulting from transformer load current.  One curve from a family of curves representing the incremental temperature for various transformers may be selected or programmed by adjustments made which simulate the incremental additional temperature which results from transformer winding current.  The total temperature value resulting from the addition of both the top oil temperature and the incremental temperature are used to control indicators, cooling fans, circuit trips and retain an indication of the highest temperature occurring during the time period of interest.

Abstract: Abstract INTEGRAL CONTROL OF A DEPENDENT VARIABLE IN A   SYSTEM HAVING AT LEAST TWO INDEPENDENT VARIABLES WHICH INFLUENCE THE DEPENDENT VARIABLE      A method and apparatus for integral control of a dependent variable in a system having at least two independent variables which influence the dependent variable is disclosed.  A difference signal indicative of the difference between the sensed dependent variable and a reference is integrated and provided to a hysteresis transfer function.  The output of the transfer function is subtracted from the integrated difference signal and the resulting signal is used to control an independent variable which thereby influences the dependent variable only for small magnitude signal variations in the integrated signal. The integrated signal is used to control another independent variable for large magnitude signal variations in the integrated signal.  The other independent variable is typically only capable of influencing the dependent variable for large magnitude signal variations.

Abstract: ABSTRACT OF THE DISCLOSURE     An encryption/decryption system for a communication channel in-creases the number of values for the encryption key variable without increasing the length of a cipher feedback register.          This is done by providing a selector to select one from many local and prestored keys for each frame.  The transmitting end has a first storage register, a first memory, a first selector, and an encrypting circuit.  The encrypting circuit combines a randomized signal with the input signal to form an encrypted signal.  As cipher feedback, the first storage register provides bits of the encrypted signal as addresses to the first memory, which outputs corresponding random numbers.  The first selector selects from the random number data to form the coding randomized signal fed to the encrypting circuit.  The receiving end has a second storage register, a second memory, a second selector, and a digital signal decoding circuit.  The second storage register stores bits of a received encrypted signal and outputs them in parallel as addresses.  The second memory receives these address-es and outputs corresponding random numbers.  To enable decoding, the working and stored contents of the first and second memories are identical.  The second selector, operating the same way that the first operates, selects from the identical random number data to form a decoding randomized signal.  The decoding circuit combines the received encrypted signal with the decoding random-ized signal to reproduce the input digital signal.

Abstract: HOT GUNNING ROBOT FOR FURNACE LINING ABSTRACT     During refining of scrap, a lining  on the wall or the bottom of a furnace is eroded by high temper-ature molten steel and slag.  Sludgy lining material is spouted toward the worn lining  by  a hot gunning robot.  The lining material is solidified  under the high temperature condition immediately after the tap-ping  and the furnace lining is mended.      The hot gunning robot moves a gunning nozzle  along a verti-cal  center line of the furnace and changes the tilt-ing angle of the gunning nozzle  to  perform mending of the required portions continuously and  automati-cally.  The hot gunning robot  comprises  a  gunning nozzle, a shifter and a nozzle carrier.  The shifter transfers the nozzle carrier from a housing position to  a mending position of the furnace  and  consists of  parallelogram-links and an actuator which  moves the links.   The nozzle carrier travels in an upright posture, and not only the furnace wall but also  the furnace bottom is mended  by the rotating  and tilt-ing  of the gunning nozzle.    A water feeding  tube is fitted  on a vertical feeding  pipe  which  feeds the lining  material and homogeneous  sludgy  lining material is obtained  by  mixing the lining material powder  with  water spouted through a mouthpiece. The  sludgy lining material is introduced  into  the gunning nozzle smoothly by guide vanes provided in a cylindrical  nozzle supporter.    The nozzle carrier is  partitioned into a driving chamber  and  an  air chamber and both of chambers are cooled  by  feeding air.  A driving system and a bearing system for  the vertical feeding pipe is protected from  the heat of the furnace.  Swinging  of the long vertical feeding pipe is prevented by a stabilizer.

Abstract: Abstract of the Disclosure:     For a transmitter of a mobile station of a radio communication network which is typically a mobile radio telephone network, a power supplying arrangement is intermittently energized before continually energized to make the transmitter deliver a speech signal to another mobile station through a base station of the network.          More particularly, the power supplying arrangement is temporarily energized in response to a down-loop indicating signal to transmit a specific up-loop signal after once deenergized immediately subsequent to transmission from the transmitter of a known pre-call response signal.  After again deenergized, it is preferable that the power supplying arrangement is intermittently energized upon reception of an intermittent succession of call signals and then continuously energized after the mobile station is put into an off-hook state for transmission of the speech signal.

Abstract: ABSTRACT OF THE DISCLOSURE     Method for joining thermoplastic cores having spaced, longitudinal surface grooves for receiving optical fibers or electrical wires.  A heat shrinkable plastic sleeve is applied over the end of one of the cores.  A piece of a core selected so that the ends of the grooves match, at each end, the grooves of the cores to be joined, is inserted between the ends of the cores in abutting relation with the cores, and malleable metal elements, longer than the piece and having the cross-sectional shape of the grooves are inserted in the grooves of the piece with the ends thereof in the grooves of the cores.  The sleeve is slid over the elements-piece assembly and heated so that it shrinks therearound, so that the plastic of the piece and the cores is softened and the grooves conform to the shape of and embed the elements and so that the ends of the piece fuse with the ends of the cores.  If the cores have a central resistant element, the resistant elements are bared so that their combined lengths equal that of the length of the piece and are mechanically joined, before the piece, which is a longitudinally slit sleeve, is inserted between the core ends and over the joined resistant elements.
