Abstract: 47,367 CURRENT LIMITING CIRCUIT BREAKER WITH IMPROVED MAGNETIC DRIVE DEVICE              ABSTRACT OF THE DISCLOSURE         A current limiting circuit breaker comprises an improved slot motor magnetic drive device.  The threshold level of overload current which produces current limiting action is raised, yet the degree of current limiting action during high overload currents is maintained by placing a thin saturable magnetic steel plate across the open end of the slot motor magnetic drive device.  During overcurrent conditions below the threshold value, the plate shunts most of the magnetic flux and prevents production of magneto-dynamic force upon the contact arm.  Above the threshold level, the overcurrent generates magnetic flux sufficient to saturate the plate and forces additional flux into the air gap where the flux interacts with the contact arm to drive the contact arm into the slot and produce current limiting action in a normal manner.

Abstract: Abstract of Disclosure This disclosure is concerned with compensating for unsymmetrical antenna receiving or transmitting patterns caused by unbalanced driven element feed, by compensatory unsymmetrical interaction with parasitic director and/or reflector elements.  An improved Yagi-type antenna has, in combination, a coaxial-line-fed antenna having one portion connected to the inner line and the other portion connected to the outer line of the coaxial line and thus producing an unsymmetrical pattern.          Parasitic conductive elements are spaced from but near the antenna and comprise portions corresponding to and extending substantially parallel to the portions of the antenna.  The parasitic conductive element portion corresponding to the other portion of the antenna is of greater dimension than the portion corresponding to the one portion of the antenna to introduce compensatory unsymmetrical parasitic interaction to render the pattern symmetrical.

Abstract: U. S. SERIAL NO. 854,306 Filed Nov. 23, 1977 Dkt. No.                 REMOVAL OF BACTERIA                                Abstract This invention relates to an ion exchange column for the removal of bacteria from a liquid medium wherein the column has, as an indicator to indicate when the column capacity for removal of bacteria is exhausted, a filter having submicron pores which will become plugged after a short period of usage with an exhausted bacteria-removing ion exchange column so that pressure build up will noticeably reduce the flow of liquid exiting from the filter thereby indicating to the user that the ion exchange column is exhausted. This invention also relates to a process for removing bacteria from a liquid medium wherein a bacteria containing medium is passed through an ion exchange column capable of removing such bacteria and then through a filter having submicron pores. When the capacity of the ion exchange column for removing bacteria is substantially exhausted, bacteria are removed by the submicron filter which quickly plugs. The build up in pressure, as a result of the plugging of the submicron filter, results in a reduction in the flow of liquid exiting from the filter and thereby indicates to the user that the ion exchange column has become exhausted for its intended purposes.

Abstract: PENETRATION HARDNESS TESTER    WITH DIGITAL READOUT                  Abstract of the Disclosure A semi-automatic penetration hardness tester for measuring hardness of a test specimen in a selected one of a number of hardness number scales.  A digital display in-dicates penetrator displacement during application of a minor load in a first mode of operation and may be monitored by an operator to achieve a penetrator displacement within a pre-selected range corresponding to application of a minor load of desired magnitude.  A control circuit senses manual ini-tiation of a major load application and automatically scales the minor load penetrator reference position to a reference hardness number corresponding to and correlated with the selected hardness number scale.  The control circuit also senses an operator error during the test procedure and automatically aborts the test.

Abstract: ABSTRACT The invention relates to metal clad, pressurized gas insulated high voltage switching apparatus.  A movable contact rod crosses a switching gap in the "on" position and together with a coaxial field electrode can be moved into an intermediate position in which the field electrodes are close together while the contact rod is retracted from the gap.  Wandering off of the arc produced during closing and opening is prevented by a lever linkage which is provided with driving links for the contact rod and the field elect-rode and which controls the motion cycles of the contact rod and the field electrode during the closing and opening process.  The invention ensures that the field electrode moves, during the closing process as well as during the opening process, unequivocally and independently of heating, wear and manu-facturing tolerances.

Abstract: ABSTRACT           A waste gas recovery system employs a compressor which takes in raw waste gas from an inlet knock-out drum and passes compressed gas through a heat exchanger to an outlet knock-out drum.  The temperature at the outlet of the compressor is sensed by a device which operates valves to inject liquid coolant into the compressor inlet and to re-circulate gas back from the outlet of the outlet knock-out drum to inhibit an excessive temperature rise.  A pressure-sensing device senses the pressure of the gas passing into the compressor and controls both the speed of the compressor and an adjustable throttle valve to regulate the gas flow. The throttle valve is closed automatically should there be a fall in the pressure of the gas at the inlet below a safe level.  In this event, further pressure-sensing devices act additionally to close the re-circulating gas valve and a further valve in the main inlet flow path to reliably isolate the compressor.
