Abstract: ABSTRACT OF THE DISCLOSURE            An electric vehicle traction motor control circuit includes a main thyristor in series with the motor armature.          A second thyristor is connected in series with a commutating capacitor across the main thyristor which can be switched off by firing the second thyristor so that the motor current is diverted into the commutating capacitor.  A third thyristor is connected in series with an inductor across the commutating capacitor and serves when fired to reverse the voltage re??ding on the commutating capacitor following commutating.  The reversed voltage on the capacitor is detected and is used to control upper and lower current limit signals set by a driver operable control so that the capacitor is not called upon to receive a large current when it is in a low voltage condition.

Abstract: ABSTRACT OF THE DISCLOSURE         A tumbler assembly for mixing, storing and feeding particulate materials and for transferring heat between different materials which includes a tumbler having a lower portion in the form of a hollow inverted lower cone enclosed by a circular cover.  The cover has an axial inlet and the cone has an axial outlet.  The tumbler is rotatably supported with its axis inclined at an angle of 30° to 75° with respect to the horizontal, the tumbler having driving means for rotating the same at a speed within the range of a fraction of a revolution per minute up to several revolutions per minute.  The cone has an included angle within the range of 80° to 135°.  The outlet is restricted to control the rate of flow so that a body of material is maintained in the tumbler, the material being constantly mixed by cascading of material across the surface of the body and movement of material within the body as the material is withdrawn along a multiplicity of paths which, by reason of the conical shape and inclined axis, precess orbitally through the mass.  In an alternate embodiment, the body of material completely fills the tumbler and the mixing occurs primarily within the interior of the body.          In another alternate embodiment the cover, which is preferably of conical shape, is fixed, that is, non-rotatable, and the lower cone is proportioned in accordance with the function to be performed.  A tumbler may be used for handling a single particulate material, either heated or not, or a combination of particulate materials, respec-tively coarse and fine, having different inlet temperatures, so that the tumbler serves as a heat exchanger.  In one embodiment the tumbler includes a fuel burner for heating a material contained therein.

Abstract: ABSTRACT    A fast warmup, high capacity, no splash, self-cleaning humidifier for a proof box.  The device has an aluminum steam generating heater pan including at least one electrical heating element cast into its base.  A reservoir and a float controlled valve attached to the heater pan by a dog leg conduit keeps the level of water in the heater pan at a depth of about one-half inch.  The heater pan is mounted for rotation about a horizontal axis, and a drip pan is located beneath the heater pan. For cleaning of accumulated minerals, scale and the like from the heater pan, the heater pan is allowed to heat to over 212° F. while dry.  Cooler water from the reservoir is then suddenly added to the hot, dry heater pan resulting in the removal of said accumulated minerals, scale and the like from the heater pan due to thermal shock and the vigorous boiling of the added water.  The contents of the heater pan are then dumped into the drip pan by rotating the heater pan about said horizontal axis.

Abstract: Abstract of the Disclosure An energy conserving process furnace has a recuperator to utilize heat derived from exhaust gases in order to reduce fossil fuel consumption of the furnace.  Elongated, enhanced surface ceramic heat exchanger tubes are used in the recuperator to recover heat energy from the exhaust gas.  A preferred sealing arrangement is used between the metal and ceramic tubes to con-tain the combustion air.  Heat is added by the recuperator to combustion air used in a fluid fuel burner.  The ceramic tubes are provided with vibration protective mechanisms to prolong use-ful life under severe mechanical vibration encountered in some applications.     In a method of operating a slot furnace, exhaust gas is exhausted from a side of the furnace through the slot or a passageway having an elongated horizontal cross section.  In the preferred arrangement a second passage or air curtain passageway is positioned adjacent the first passageway to permit proper gas flow through a recuperator.  The recuperator is designed to recoup heat from exhaust gas in the first passage-way and provide such heat as energy to heat combustion air used in the furnace.  The second passageway by-passes the recuperator to avoid passing colder room air through the recuperator and to protect the operator from high temperature exhaust gas.     The heat exchange ceramic tubes are designed to operate at temperatures of 1300°F and above without damage and with good sealing properties between elements.     The system preferably includes a recirculating burner means which acts to reduce the combustion air requirements and to provide a combustion zone low in oxygen so as to prevent scale formation and oxidation of metals being treated in the furnace area.  The recirculating burner has a flame front outside of the burner in the combustion chamber.

Abstract: ABSTRACT OF THE DISCLOSURE        A small, compact heating device for warming small quantities of edible liquid ready for consumption comprises a heat tube having an outer heat insulating layer covering its central, intermediate zone, and a heat source for heating the evaporator end zone.  The device is used for heating liquid in a cup or similar container, by immersing the condenser end of the heat pipe in the bottom of the liquid in the cup, with the insulated portion contacting the liquid surface.  The heating means is applied to heat the evaporator end of the heat pipe, and the heat is transferred by the heat pipe to the bottom of the liquid for efficient heating of the liquid ready for consumption.  The evaporator end may be surrounded by a chimney, for more efficient heating thereof, and to conduct combustion fumes away from the edible liquid.          The fuel may be solid hydrocarbon fuel, and placed on the bottom wall of the chimney for combustion.  Alternatively it may be a liquid or gaseous fuel, with the heating means being, for example, a cigarette lighter releasably clamped to the heat pipe in the vicinity of the end of the chimney.          The apparatus is particularly useful for hikers, skiers, campers and troupes on outdoor military exercises, who require hot nourishment but cannot conveniently carry bulky heating apparatus.

Abstract: ABSTRACT     A spirometer having an inflatable bellows, is provided with a movable member which runs along a track.  The configuration of the track is adjustable, and by such adjustment the configuration is set locally to give a variable resistance to movement of the member and, consequently, to inflation of the bellows.  Callibration is achieved in a simple manner by adjusting the track at the position of engagement with the movable member as the bellows is inflated progressively with measured amounts of air.  Adjustments made correctly are not upset by adjustments made later in the callibration operation.   In contrast, with the known procedure of callibration by moving the bellows, or by loading the gussets of the bellows with wires or strips, during such progressive inflation,  adjustments made do not affect adjustments made at an earlier stage of the inflation.

Abstract: ABSTRACT:  "Switching circuit comprising a plurality of input channels and an output channel"         A switching circuit in which one out of a plurality of input channels is connectable to an output channel via one of the switching devices in the circuit. Each of the switching devices comprises an emitter-coupled pair of transistors which have a switchable current source in the emitter lead, the base of the first and the second tran-sistor, respectively, of each pair being connected to one of the inputs and to the output, respectively. The output channel of the circuit comprises a transistor the emitter of which is connected to the output and the base to the interconnected collectors of the second transistors, this junction point being connected to a voltage-carrying ter-minal via a resistor. Via a selection switch which is con-nected to the switchable current sources only one of the input channels can at all times be connected through to the output channel. To increase the cross-talk attenuation, the non-conducting current sources are driven to the saturated state, non-conduction being ensured by limiting the maximum and minimum value, respectively, of the input signal with respect to the current source switching voltage.
