Abstract: ABSTRACT OF THE DISCLOSURE      An electrical system which comprises     a temperature-sensitive device comprising a PTC or NTC element,     a load in series with the temperature-sensitive device and     a control device in parallel with the load and the temperature-sensitive device.  The control device is a device whose resistance can be changed from a high value (which may be infinite) to a low value or vice versa, by a change in the electrical or physical environment thereof, e.g. a diode, triac, thyristor, PTC device or NTC device.  By an appropriate change in the power source, e.g. its size or direction, or in the physical environment of the control device, e.g. its temperature, the relative resistances of the temperature-sensitive device and the control device can be reversed, thereby isolating or activating the load.  The system is particularly useful for isolating a remote load, e.g. a telephone, while retaining a continuous circuit e.g. through the legs of a telephone circuit, for example for test purposes.

Abstract: ABSTRACT: "Nuclear magnetic resonance apparatus."     About an electromagnetic magnet system of an NMR tomography apparatus there is arranged a second electromagnetic magnet system which is capable of generat-ing a magnetic field such that the external stray field of the first magnet system is compensated for. When use is made of superconducting magnet coils, the reduction of the measurement field which is caused by the compensation magnet can be readily cancelled. Using a construction where the surface O2 of the cross-section of the second magnet system amounts to twice the surface O1 of the cross-section of the first system, the field at the area of the windings of the first system is also compensated for in the case of energizing where O1 x H1 = -O2 x H2, with the result that substantially larger persistent currents are permissible.

Abstract: ABSTRACT OF THE DISCLOSURE    A pneumatic and hydraulic system for operating fluid-operated cylinders is provided.  The system employs both air and oil in a tank with the oil supplied at least to the blind side of a piston in the cylinder.  The pressure of the oil is controlled by the pressure of the air in the tank and a blocking valve is employed between the tank and the cylinder to control flow of the oil.  The use of the oil and valve enables the position of the piston and the piston rod to be closely controlled so that the apparatus can be used for applications where more complicated apparatus was pre-viously required.  Two of the air/oil tanks can also be em-ployed to control the supply of oil to both sides of the pis-ton in the cylinder for accurately positioning same.

Abstract: SYSTEM FOR RATING ELECTRIC POWER TRANSMISSION LINES AND EQUIPMENT                              ABSTRACT OF THE DISCLOSURE     A system for determining the current carrying capability of one or more overhead power transmission lines monitors one or more spans of each line on real-time basis and identifies the span having the lowest current carrying capacity which in turn establishes the maximum capacity of the entire line. The thermal state of each monitored line span is determined by measuring the conductor temperature, line current, solar radiation, ambient temperature, and in some cases wind speed and wind direction. These parameters are montiored by a sensor-transmitter unit that may be removably clamped on the line conductor which may range in size from one to several inches in diameter, and includes a radio transmitter for transmitting sensed data to a receiving substation. The data from the sensor-transmitter is multiplexed and transmitted by a telecommunications link to a computer which automatically determines line capacity using the real-time data and also calculates the time required for the "critical span" having the lowest current capacity to reach its maximum safe temperature based on any of a number of step changes in load demands. Each sensor-transmitter may include sensors for monitoring the current level, conductor temperature, solar radiation impinging on the conductor, ambient temperature, wind direction and velocity and conductor sag. These sensors and the transmitter are enclosed in a corona-free housing and are powered by a power supply that includes a transformer core which surrounds and is inductively coupled with the monitored conductor. The core is formed in an upper and lower portion which are siftable relative to each other upon opening and closing a pair of conductor clamping jaws in order to permit the conductor to be introduced into and withdrawn from the core and to allow the clamping jaws to fit a range of conductor diameters while maintaining constant air gaps between the upper and lower core portions.

Abstract: ABSTRACT OF THE DISCLOSURE         If in a high-voltage d-c transmission system (HVDCTS), a resonance frequency of an a-c voltage network (NB) connected to the inverter (1B) is located in the vicinity of a voltage component contained in the a-c voltage network, a resonance frequency which often cannot be compensated by a current regulator controlling the rectifier stage (1A) is coupled into the d-c circuit of the HVDCTS via the inverter.     Therefore, resonance phenomena which requires an emergency shutdown of the HVDCTS are generated.  Therefore, a pilot quantity (U'd) is formed with a defined phase shift relative to the resonance oscillation of the HVDCTS voltage and added to the output of the current regulator.  Thereby, a constant HVDCTS current can be generated for a given operating point and the resonance in the a-c voltage network (NB) can be damped.  If the resonance oscillation is determined by two quantities (U'd, i'd) of, respectively, the HVDCTS voltage as well as of the HVDCTS current, stable damping of the resonance phenomena can be achieved by the pilot control described with the two quantities even for deviating operating points.

Abstract: ROTARY-TYPE FEEDER MACHINES AND METHODS         ABSTRACT OF DISCLOSURE          A rotary feeder feeds sheets or board-like articles to nip rolls in a box-making machine.  The boards are successively and individually fed from the bottom of a stack whose forward edge engages a gate below which the boards are fed by driven feed members such as wheels, rolls or endless belts which engage the underside of the lowermost board.  To raise and lower the boards relative to the surface of the feed members, a vertically recip-rocable grate is provided between the drive members.  The grate and drive members are mounted in a vacuum box in which a vacuum is established to hold the boards in proper position on the feed members when the grate is lowered.  The vacuum is also utilized to hold the boards with sufficient force to produce necessary friction between the boards and the feed members for feeding.          The feed members are driven through an oscillating rocker shaft and gearing in two opposite directions, one of which serves to convey the boards below the gate to the nip rolls and the other of which serves to relieve pressure of the board against the gate prior to conveyance to the nip rolls.  The grate is actuated through oscillatable shafts connected to the grate and driven from a cam and cam-follower assembly which, in turn, is driven from a crank gear that is also employed to drive the rocker shaft through a linkage or quick return slide mechanism.  A latch device is also provided to releasably hold the grate in raised position above the feed members to interrupt the feeding operation.

Abstract: ABSTRACT OF DISCLOSURE           Protective coatings are applied to substrate metals by coating the metal surface, e.g. by dipping the substrate metal in a molten alloy of the coating metals, and then exposing the coating at an elevated temperature to an atmosphere containing a reactive gaseous species which  forms an oxide, a nitride, a carbide, a boride or a silicide.  The coating material is a mixture of the metals M1 and M2 of which Ml forms A stable oxide, nitride, carbide, boride or silicide under the prevailing conditions and of which M2 does not form a stable oxide, nitride, carbide, boride or silicide.  M2 serves to bond the oxide, etc. of Ml to the substrate metal.  Mixtures of M1 and/or M2 metals may be employed.  This method is much easier to carry out than prior methods.
