Abstract: Abstract of the Disclosure A closed container partially filled with liquid with exhaust gas inlet and outlet devices.  Internal structure provides a path for the gases, particularly furnace exhaust gases, between inlet and outlet devices and, while passing along the path, the gases are passed through the liquid which absorbs heat from and removes constituents from the gases.  One embodi-ment passes the gases physically through the body of liquid whereas in an alternate, gases pass over the liquid body and are subjected to a spray which causes heat transfer and removes exhaust constitutents from the gases. Various devices can be used to agitate the liquid, automatic controls and operators can be used to maintain desired liquid level, and outlets, which can include automatic controls, are provided to remove collected sludges or constituents.  Heat exchangers using conduction, radiation and convection principles of heat transfer can be added to utilize recovered heat energy.

Abstract: D.C. MOTOR CONTROL HAVING GATING CONTROL     OF A FULL-WAVE RECTIFIER SYSTEM               ABSTRACT OF THE DISCLOSURE        A D.C. motor is selectively connected to receive  ener-gizing power from a polyphase power source through a dual bridge rectifying system providing six pulses per cycle of the poly-phase power supply by full-wave rectification and selectively operable to supply current of either polarity for motoring or regenerative mode of operation in either  direction and capable of operating a transportation system such as an elevator, for example.          An improved gating control system includes a plurality of gating channels each supplying gating pulses to one of the rectifying elements. Each channel includes three cascaded solid-state switch-ing circuits operating in response to an analog output of a summing circuit receiving a compensated error signal, an alternating phase reference signal, and a constant reference signal for prop-erly controlling the firing angle of the associated controlled rectifier.  The output cascaded switching circuit of each channel selectively and operatively connects a storage capacitor to an output transformer having a primary winding interconnected with a filter eliminating high frequency signals and a secondary winding shunted by a resistor and directly connected to the associated controlled rectifier  The intermediate cascaded switching circuit of each channel provides an output circuit connected through a uni-directional conducting first circuit to control the output cascaded switching circuit of the same channel and further connected through a unidirectional conducting second circuit to an output switching circuit in another channel so that the two interrelated channels will both render the associated rectifying devices conductive to energize the D.C. motor.  Two back to back series connected selenium rectifiers operating as an A.C. device are connected across the dual bridge output and  clip undesirable transient peaks of a pre-determined magnitude substantially greater than the rating of the individual rectifier devices.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates generally to aircraft deicing systems, and, more particularly, to deicers for use in helicopters.  The problems relating to the formation of ice on aircraft are well known, and date from the early days of aviation.  Various techniques have been employed in an attempt to avoid the problem of aircraft icing.  Early deicing devices were mechanical, employing an inflatable cover or boot to crack the ice layer.  Other prior art deicers employ electric resistance heating elements buried beneath the airfoil surfaces.  The principal problem with these is that they heat a large section of airfoil surface, whether covered with ice or not.  Helicopters are, of course, just as prone to icing problems as fixed-wing aircraft.  In addition, there is a practical difficulty in supplying deicing power to a rotating surface.  The present invention resides in aircraft deicing apparatus, and a related method for its use, in which microwave electromagnetic energy is transmitted into a surface layer of ice, and is dissolved in the ice as heat, melting the ice layer in a very efficient manner.  The apparatus of the invention includes means for generating microwave electromagnetic energy, distribu-tion means for transmitting the energy to a surface of the aircraft on which ice can form, and coupling means, for coupling the microwave energy for transmission into the surface layer of ice in such a manner as to propagate the energy through the ice layer acting as a surface waveguide.
