Abstract: A method and device for use in breathing where the ambient temperature is uncomfortable is the subject of the present invention. An air intake conduit is enclosed by a sack and communicates with a face mask that covers the nose and mouth of the wearer. Both the intake conduit and the enclosing sack extend in a curvilinear path over the head of the wearer to take advantage of heat normally lost through the head. A head covering may be used to further increase the efficiency of the heat exchange between the head and the air passing through the sack and the intake conduit. One-way valves on the inlet and outlet openings assure segregation of inhaled and exhaled air. Exhaled air is passed into the sack where it is held in heat exchange relationship with the incoming air moving through the conduit as well as with body heat radiated by the wearer's head. An exit opening at the end of the sack distal from the point where exhaled air enters allows the exhaled air to eventually pass from the sack.

Abstract: A refractory lined firebox is encased in a low profile furnace shell of generally rectangular configuration. Mounted on top of the firebox within the furnace shell is a heat exchanger which provides alternating passageways at right angles to one another through which flue gas and air to be heated flow in heat exchange relationship. The heat exchanger and firebox are so related that the axes of the passageways are inclined from the horizontal and the flow through them is generally upward as well as lateral. The furnace includes special combustion air ducts for use in combustion of the solid fuel. The furnace is also equipped with a back-up liquid fuel burner and a control system which activates and operates the liquid fuel burner in response to total consumption or burn out of the solid fuel in the firebox.

Abstract: The present invention comprises an improved animal dust bag for holding and dispensing powdered insecticide. The bag arrangement permits the bag to be hung from two spaced apart points when it is desired to avoid turning of the bag, or from a single overhead point when turning of the bag is of no concern. A flap extends upwardly from the top of the bag and presents an eyelet for receiving the two tie strings. When the two tie strings are threaded through the eyelet there is virtually no possibility of an animal sticking its head or a horn between the tie strings and pulling down the bag or damaging it. The eyelet also assures that the bag will be held relatively even, thus avoiding compaction of the powdered insecticide in one corner. A horizontal hanger bar extends across the top of the bag and presents two eyelets on either side so that when attachment at two spaced apart points is desired, the two eyelets of the hanger bar will avoid strain being placed on the bag material itself.

Abstract: This invention discloses a method and device for reducing fuel consumption by a locomotive system comprised of a plurality of tandem diesel locomotives electrically interconnected so that one of the units is a lead unit and the remaining units are trailing units. In particular, the fuel saver arrangement of the present invention is capable of selectively placing one or more of the locomotives in the system in a "throttle one" power position without causing any significant reduction in the operating efficiency of the system's safety equipment. The locomotive is placed in the throttle one power position by means of switching relays that are operable to override the normal throttle control circuit of the locomotive. These relays respond to a fuel save signal that is generated in the control box located on the lead unit. The control box includes a fuel save switch operable to initiate and terminate the fuel save operation and a unit selector switch operable to select the locomotive to be reduced in power.

Abstract: The present invention deals with a microprocessor implemented method and system suitable for use in a mail sorting machine to sort the envelopes into common groups, assign each group a particular sort bin and generate a coded bin designation signal. The envelopes to be sorted are run through the machine in two passes. During the first pass, the system causes each of the envelopes to be deposited in a designated sort bin in accordance with a sort table which was programmed into the microprocessor prior to the first pass. The microprocessor also compiles a list of the zip codes of each envelope moving through the machine and maintains a count of the number of envelopes having each zip code. Once the first pass is completed, the microprocessor assembles the compiled zip codes into common groups and assigns each group a bin location. The microprocessor then assembles the bin locations into a sort table and outputs a list of loading instructions.

Abstract: The present invention encompasses a method and apparatus for assisting in the operation of air control dampers. An air deflector is positioned downstream from a rotatable damper in an air conduit. The deflector is positioned to direct air moving over one side of the damper against the damper during opening to assist in the opening movement and thereby reduce the amount of weight which would otherwise be required. The same deflector is positioned so that upon closing of the damper air will be deflected against the opposite side of the damper blade to augment the torque forces tending to close the damper while also reducing the pressure drop from one side of the damper to the other. In another embodiment of the invention a sail blade is provided upstream from the control damper to assist in closing the damper at low flow conditions.

Abstract: A method of removing sulfur oxides of H.sub.2 S from high temperature gas mixtures (150.degree.-1000.degree. C.) is the subject of the present invention. An electrochemical cell is employed. The cell is provided with inert electrodes and an electrolyte which will provide anions compatible with the sulfur containing anions formed at the anode. The electrolyte is also selected to provide inert stable cations at the temperatures encountered. The gas mixture is passed by the cathode where the sulfur gases are converted to SO.sub.4.sup.= or, in the case of H.sub.2 S, to S.sup.=. The anions migrate to the anode where they are converted to a stable gaseous form at much greater concentration levels (>10X). Current flow may be effected by utilizing an external source of electrical energy or by passing a reducing gas such as hydrogen past the anode.
