Abstract: 1536528 Automatic control of fuel injection in I C engines NISSAN MOTOR CO Ltd 30 May 1977 [31 May 1976] 22773/77 Heading G3N [Also in Division F1] In a multi-cylinder I.C. engine having electronic fuel injection, fuel economy is achieved when the engine is lightly loaded by stopping injection to some of the cylinders. An engine speed sensor provides a signal to a first function generator 3 which produces a high level reference signal F 1 which varies linearly with engine speed up to 2000 r.p.m. and then remains constant. A second function generator produces a signal F2 of the same type but of smaller amplitude. Intake manifold depression is detected by sensor 1 and the output of the sensor is compared with signals F 1 and F2. When the load increases so that the load signal exceeds signal F1, all the cylinders are active. When the load decreases so that the load signal is less than F2, some of the cylinders are made inactive, and when the load signal is between F1 and F2, the number of active cylinders remains constant.

Filed: 1971-04-19
Abstract: 1335433 Transistor oscillators STATITROL CORP 19 April 1971 [19 Feb 1970] 23018/71 Heading H3T [Also in Divisions G1 and G4] An oscillating detector includes an ionization chamber 10 connected to the gate electrode of F.E.T. 2 which is energizable through a transistor T11, which, when the gate capacitance of the F.E.T. 2 has charged through the resistance of ionisation chamber 10, de-energizes the F.E.T. When the supply E is first applied transistors T11 and T9 are ON and F.E.T. 2 is energized, the current I L  through R L  being such as to maintain transistors T6, T7, T8 turned OFF. As the gate capacitance 4 charges through ionization chamber 10 I L  decreases until transistor T6 is biased ON resulting in transistors T7, T8 switching ON and transistor T11 switching OFF. The supply E to the F.E.T. is thus terminated and voltage V 1  falls. Switch T11 is maintained in an OFF state until capacitor 18 charges through resistor R19 sufficiently to switch OFF transistor T8 allowing transistor T11 to turn ON again. During the period transistor T11 is OFF the gate capacitor 4 discharges. If smoke enters chamber 10 the conductivity of the latter decreases thus increasing the time for charging the capacitance 4. Alarm relay 20 is energized by the output of an integrating amplifier formed by transistors T21, T22 and resistor 24 and capacitor 25, the time constant of the latter determining the length of time for which the supply must remain on before sufficient voltage is present across capacitor 25 to turn on transistor T22. A lamp may be used to indicate the alarm, the lamp flashing on and off under normal conditions but remaining on under alarm conditions.

Title: Method of oxidizing organic compounds by nitric acid
IPC: C07B35/04
Filed: 1951-10-10
Abstract: Organic compounds are oxidized with nitric acid in a substantially vertically-extending elongated reaction vessel such that the requisite agitation of the reactants is wholly or substantially wholly obtained by the gases evolved during the reaction.  One reactant is introduced at the bottom of the vessel and the other at the bottom or at some intermediate point, the products being withdrawn from the top.  Thus the oxidant with or without some of the nitric acid may be introduced at the bottom and nitric acid of different concentrations introduced at different levels to maintain the correct concentration inside the vessel.  The pressure is adjusted by regulating the rate of flow of the mixture.  The reaction may be catalysed by a gas blown into the vessel, e.g. nitrous fumes evolved by reaction between a liquid and nitric acid.  The reaction vessel may be smooth or may be furnished with flanges or other obstructions to increase the agitation.  It may also be filled with inert or catalytic substances.  Suitable apparatus is illustrated. Examples show the oxidation of toluene to benzoic acid, p-nitrotoluene to p-nitrobenzoic acid and p-cymene and p-xylene to terephthalic acid containing some toluic acid and nitro compounds. Reference is made to the oxidation of alkyl-substituted hydrocarbons in general, giving mono- or di-carboxylic acids; ethylbenzene and xylene are specified.  Chlorotoluenes, nitrotoluenes and toluene-sulphonic acids may similarly be oxidized to substituted benzoic acids.
