Abstract: AN IMPROVED AC SYNCHRONOUS RELUCTANCE MOTOR          Abstract of the Disclosure The present invention relates to an improved rotor for an AC synchronous reluctance motor.  The rotor is provided with a central shaft wherein the pull-in torque, pull-out torque, power factor and efficiency of the motor are related to the ratio of direct axis reactance to the quadrature axis reactance of the motor.  The rotor has a magnet for developing a synchronous torque in response to an externally generated rotating magnetic field under conditions of rotor rotation speed equal to rotation speed of the externally generated magnetic field.  The magnet is comprised of predetermined laminations of soft magnetic material interspersed with non-magnetic material.  The laminations extend axially parallel to the central shaft and increase quadrature axis reluctance thereby decreasing quadrature axis reactance.  As a result, the ratio of direct axis reactance to quadrature axis reactance is increased.

Abstract: ABSTRACT OF THE DISCLOSURE:     Tubular wrapper closing combination made up of a bar of clips each adapted to close a tubular wrapper, bag or the like, and a closing device for each clip.  Each such clip is a curved U-shaped length of metal wire of which the ends of the legs thereof are  bent inwardly toward one another and each leg has an outwardly bulging  portion.  The closing device is formed with a clip guideway and is provided with a mechanism for forcing advancement of the bar toward the guideway to feed the clips into it.  The closing device further includes a die in the guideway for closing the clips and a retractable punch for advancing one of the clips at  a  time into the guideway towards the die and thereby to close around the tubular wrapper. The punch has a pair of side portions with respective recesses for receiving the outwardly bulging portions of the legs of the clips so that, upon retraction of the punch, should the clip not be closed, it will he retracted with the punch so as not to permit the next clip of the bar to be fed into the guideway.

Abstract: METHOD AND APPARATUS FOR REDUCING INTERFERENCE        BETWEEN PLURAL RADIO ALTIMETERS                      Abstract of the Disclosure A method and apparatus for independently controlling a CWFM radio altimeter to reduce interference from another nearby altimeter employs a high-Q filter outside the bandpass of the signals which are developed and decoded for altitude indication to detect an approaching interference signal received from the other altimeter and produce an output to a threshold detector.  When the output of the filter exceeds a predetermined level, the threshold detector causes the transmitted frequency of the altimeter to be stepped.         In one embodiment, a digital counter is provided to cyclically count up and down at a desired sawtooth modulation frequency.  The output of the counter is applied to a digital-to-analog converter to produce an output used to control the  frequency of the transmitted signal. Additionally, the output of the counter is conducted to inputs of an adder having a preset add number therein.  When the output from the threshold detector is produced, it loads the counter immediately with the sum of the present counter output with the preset add number.  The counter then begins its count at the totalled count, thereby immediately stepping the transmitter frequency.  In redundant systems, each transmitter frequency can be shifted a different amount in an individual preset direction.

Abstract: Abstract of the Disclosure This invention relates to a method of producing articles which generate heat at a substantially constant temperature for an extended period of time ? which are able to remain in a stable state until such time as the generation of heat is desired.  The method also relates to supercooled fluids produced by such methods.  The method involves the processing of supercooled fluids such as hypo to produce this stable state.  As a first step, a suitable material such as ethylene glycol may be added to the super-cooled fluid to stabilize the supercooled fluid and to decrease the generation of heat in the supercooled fluid to obtain a desired temperature.  The mixture is then heated to a relatively high temperature considerably above the melting temperature of the supercooled fluid.   With the mixture at the high temperature, water is added to provide a particular specific gravity and an alkali is added to provide a particular pH.     The mixture may then be poured into rupturable pouches while being maintained at the high temperature.     The mixture in the pouches is then allowed to cool slowly to ambient temperatures and is placed in a separate container with a triggering material.

Abstract: Abstract of the Disclosure The present invention relates to a molten metal partial plating method, and apparatus therefor in which a plating preventing film is formed on an area of the substrate material not to be plated, and the material is then entirely immersed in a plating bath of a molten metal.  The primary object of the present invention is to provide a plating preventing film having an excellent plating preventing effect on the area not to be plated, of the substrate material. The plating preventing film should have good adherence, and should be capable of being produced with ease at a low cost, so that a steel plate having one surface completely plated can be obtained very easily. This object can be attained by forming the plating preventing film of carbon, or mainly of carbon and containing an inorganic compound which does not decompose at the plating temperature and which does not react with the plating bath.  The present invention is effectively applied to one surface plating with zinc, aluminum, tin or the like.
