Abstract: S P E C I F I C A T I O N          TO ALL WHOM IT MAY CONCERN:           BE IT KNOWN that I, THOMAS REHBERG, a citizen of the United States of America, residing at 17931 LaHaigh, Homewood, in the County of Cook and State of Illinois, have invented a new and useful improvement in FUSE CIRCUITRY of which the following is a specification.     ABSTRACT OF THE DISCLOSURE         A control system for use in electrically heated glass panel refrigerator doors to substantially prevent electrical shock if the glass panel is accidentally broken.  The control system has an interlock switch for effectively disconnecting the power source from both the panel heater and the door heater of the electrically heated refrigerator door should breakage occur.          The interlock switch includes a thermal responsive device, such as a fuse, and a fuse heater.  If the glass panel is accidentally broken causing the panel heater to become dangerously exposed, the fuse heater is activated to generate a sufficient amount of heat to blow the fuse which opens the circuit to quickly and safely deactivate both the panel heater and the door heater.

Abstract: Abstract of the Disclosure A rotatable member, such as a turret at a weapons station, is controllable about an azimuth axis.          A weapon is carried in the turret with the weapon being controllable therewithin about an elevation axis.          The moments of inertia of the turret and weapon about the azimuth axis and of the weapon about the elevation axis are relatively high.  The disclosed system pro-vides for elevation and azimuth control through eleva-tion and azimuth drive trains having reflected drive train inertias which are at least two orders of magnitude smaller than the inertia of the turret and weapon about the azimuth axis and at least one order of magnitude smaller than the inertia of the weapon about the elevation axis.  Further, the system senses spurious torque applied about either axis, as for example due to the recoil of the fixed weapon, and pro-vides automatic repositioning of the controlled members about either axis to compensate for angular displace-ment caused by the spurious torque.

Abstract: ABSTRACT OF THE DISCLOSURE A process for the simultaneous production of metal-lized ores and a char.  A carbonaceous material such as coal is mixed on a weight ratio basis of about 1/2 coal to about l iron ore to about 1-1/2 or more coal to about 1 iron ore.  The coal is mixed on a weight ratio basis with the iron ore within the ratios defined above and the mixture subjected to a heat treatment of between 1800°F to about 2200°F within a substantially air tight enclosure wherein an oxidizing atmosphere is provided in the upper portion of the enclosure and a reducing atmosphere is maintained about the materials on the floor of the enclosure.  The floor of the enclosure comprises a travelling imperforate hearth with the speed of travel thereof variable so as to vary the residence time of the materials on the floor of the enclosure from the time of deposit of the materials on the hearth to the time of removal of the materials from the floor.      The mixing of the coal and iron ore within the ratios defined above and by varying the temperature conditions within the enclosure along with the residence time of the materials on the floor of the enclosure will result in the production of a highly-metallized ore, say in the neighborhood of 85% to 95% metallization or a slightly metallized ore, say in the neighborhood of about 55% to about 65%.

Abstract: IMPROVED INDICATING DEVICE FOR TORQUE WRENCHES          Abstract of the Disclosure The improved indicating device is constructed from a single piece of resilient material such as Delrin or Teflon and includes a bifurcated friction portion that is disposed in a groove in the wrench.  The friction portion is con-structed so that the tines can be deformed to pass through a narrow slot and frictional engage sides of the groove. The indicator member also includes an upstanding portion that is engageable with the pointer of the torque wrench to move the indicator as the pointer moves relative to the torque scale.  Since the indicator member is in frictional engagement with the torque wrench, the indicator remains at the maximum torque after releasing the torque from the wrench and permitting the pointer to return to zero, there-by facilitating reading the maximum torque exerted.

Abstract: 48,200 ABSTRACT OF THE DISCLOSURE A ground fault detecting circuit interrupter is taught.  A ground fault is sensed by utilizing a summing transformer  interconnected with  the three-phase current transformers for normal fault detection.  The turns ratio between the primary winding and the secondary winding of the summing transformer is kept purposely high so that the excitation current for the current transformers is made relatively  small when  compared to the normal secondary current of the current transformers.  This has the effect of improving the accuracy of the normal fault detecting portion of the circuit breaker.  The relatively high turns ratio between the primary and second of the summing trans-former usually supplies insufficient current to directly actuate the trip coil of the circuit interrupter on the occurrence of a ground fault.  However, this latter cur-rent is utilized to charge a capacitive storage element after a ground fault has been sensed.  When the capacitive storage element is fully charged, it is switched into a circuit disposition  suitable  for discharge  through  the trip  coil  of  the  circuit  interrupter  with  sufficient current flow to open the separable main contacts of the circuit interrupter.
