Abstract: ABSTRACT OF THE DISCLOSURE A self-contained electric igniter in which the ignition pilot is actuated by a rechargeable battery to supply energy for the spark provided by an igniter.  All energy for opening the valve of the main gas valve is supplied by a millivolt thermopile generator which together with additional thermopiles charges the battery.  A diode is located in the battery charging line to prevent reverse flow of current from the battery to the thermopiles.  The system has a safety valve which closes off flow of gas into the system in the event the pilot burner fails to ignite and a flame switch which closes off the flow of current to the main gas valve and consequent flow of gas into the system in the event the pilot burner is extinguished.  It also has a damper control system which is closed when the system is shut off to reduce stand-by losses and conserve energy.

Abstract: ABSTRACT      An electrochemical cell comprises a housing divided by a perforated generally horizontal plate into an upper chamber and a lower chamber Bipolar electrodes are disposed in the upper chamber above perforations in the plate, between electrolyte inlet and outlet weirs for flowing electrolyte over the plate.  The lower chamber is a gas-supply chamber for passing a gas, e.g. propylene, up through the perforations, so as to bubble the gas through electrolyte (e.g. NaBr solution) on the plate and into the upper gas-collection chamber.  A reactor may be formed by stacking several cells with their electrolyte flows in cascade.  The cell is particularly suitable for electro-organic syntheses involving a gaseous reactant.

Abstract: INDUCTIVE POSITION SENSOR WITH FAILURE DETECTOR     ABSTRACT OF THE DISCLOSURE     A primary and a secondary of an inductive position sensor are connected by a capacitively coupling means.  An output of the position sensor is connected to a level detector functioning as a failure indicator.  The capacitive coupling of the primary and secondary of the inductive position sensor results in the output of the position sensor being above a minimum signal level at every position including the position at which the sensor output indicates zero or null position.  When the sensor output falls below the minimum signal level, the level detector indicates failure.

Abstract: ABSTRACT      A mini-plant for producing silane from dichlorosilane via a redistribution reaction has produced 97% pure SiH4 at 93% efficiency  The residual impurities were monochlorosilane (2.5%) and dichlorosilane (.5%).  The silane purity of 97% achieved by operating the silane still partial condenser at 40 psig and -32°C outlet temperature was significantly higher than predicted by ideal vapor-liquid equilibrium considerations.  Laboratory equilibrium concentrations and order of magnitude reaction rates were confirmed in mini-plant operations.  Kinetic isotope studies on the mechanism of the amine catalyzed redistribution of chloro-silanes indicated the amine hydrochloride may not be the active species as originally proposed.  The hydrogenation of silicon tetrachloride to trichlorosilane appears to be a true equilibrium, approachable from either HSiCl3 or SiC14. Virtually no H2SiC12 was formed by hydrogenation of HSiCl3.

Abstract: ABSTRACT An energy conversion cycle for an internal combustion engine and an internal combustion engine capable of carrying out the process to produce work, the process characterized by the steps of forming fuel and air charges having fuel to air proportions varying from stoichiometric at full engine power to excess air at less than full engine power conditions; increasing by compression the densityand activation of the molecules of the charges supplied to a variable volume working chamber in which the fuel and oxygen in the air are reacted to produce thermal potential; controlling fuel and air distribution in the working chamber so that the excess air portion of each charge is located in an air reservoir chamber that is separated from the reaction area by an open partition area separating the working and air reservoir chambers; and through the partition area, controlling availability of oxygen in the working chamber during the reaction while permitting the oxygen to be activated in a specific manner by molecular interaction with the reaction process itself across the partition area to the extent that pressures in the working and reservoir chambers are equalized during the reaction. Diffusion of molecules of activated oxygen across the partition is controlled and such molecules sustain the reaction after its initiation in a manner that the reaction is carried out with the proportion of fuel to oxygen always on the excess fuel side of stoichiometric in accordance with requisites for rapid reaction of the fuel withoxygen. The engine is characterized by an arrangement of mechanical elements and charge forming devices including moveable pistons for varying a working chamber volume, means for controlling distribution of the fuel and air so the total fuel portion of each charge is in the working chamber at initiation of each reaction with a sufficient quantity of air to insure a rapid rate of reaction between the fuel and oxygen; and means for distributing excess air of each charge in an air reservoir chamber separated from the working chamber by an open partition area having a special control function over the molecular interaction between the chamber and reservoir, such control function insuring that, during the useful work producing part of the reaction, the proportion of fuel to oxygen in the working chamber is maintained in a fuel "rich" condition.
