Title: Fuel injection systems
IPC: F02M51/00
Filed: 1971-08-27
Abstract: 1360421 Fuel control systems ROBERT BOSCH GmbH 27 Aug 1971 [29 Aug 1970] 40214/71 Heading G1N In an I. C. engine, electrically controlled fuel supply system, the supply is controlled in dependence upon the rate of intake air to the engine by the.output of a measuring device including a temperature dependent resistor 18 mounted in the intake manifold 10 and arranged in a closed loop regulating circuit which maintains the temperature of the resistor constant, the heating current or the voltage proportional thereto being used to control the fuel supply. As shown, the resistor 18 is arranged in a bridge circuit whose out-of balance voltage is applied to an amplifier 26 whose output supplies the bridge circuit. The output voltage U s  of the amplifier can control the rate of continuous fuel supply, Fig. 5 (not shown) via a solenoid and spool valve, or an intermittent injection system, Figs. 6 and 7 (not shown). In Fig. 6, the voltage U s  is pulsed in synchronism with engine rotation, and the pulses are supplied to an integrator whose output is applied to a peak value rectifier and a monostable switching stage. The monostable switching stage, Fig. 9 (not shown) is triggered in synchronism with engine rotation and its output pulses control injection valves. In Fig. 7, the voltage U s  is integrated in an integrator which is short-circuited in synchronism with engine rotation. The integrator output is detected by a pick-up whose output is applied to the monostable stage via a holding circuit. In modifications of the circuit shown, the temperature of the intake air may be compensated for by replacing resistor 20 or resistor 19 by corresponding temperature dependent resistors arranged in the intake manifold, Figs. 3 and 4 (not shown).

Title: Nitrogen-containing polycondensates
IPC: C09D5/25
Filed: 1966-09-09
Abstract: The invention comprises branched polycondensates which contain (a) residues of compounds containing both 2 and more than 2 functional groups which are amino, hydroxyl and/or carboxyl groups, the residues being joined by ester, amide, imide, benzimidazole and/or benzoxazole group and (b) 2-(benzimidazol-21yl) benzoic acid residues or 2-(benzimidazol-21yl) benzoic acid lactam residues, joined to the remainder of the molecule through their 3, 4, 5 or 6 and 41, 51, 61 or 71 positions, by another such residue or one of the above linking groups. Compounds containing the 2-(benzimidazol-21yl) benzoic acid or acid lactam residue may be derived from (i) an aromatic compound containing 2 mutually ortho carboxyl groups and at least one other functional group and (ii) an aromatic compound having 2 mutually ortho amino-groups and at least one other functional group.  This reaction may be at 100-300 DEG  C. in a solvent, the reactants being added to the reaction vessel alternately or mixed and added in portions, the portions being of the same or differing reactant ratios.  These compounds may be polycondensed with other reactants such as polycarboxylic acids, polyamines, polyhydric alcohols, polyhydric phenols, aminoacids, hydroxyacids, aminoalcohols, and aminophenols at up to 300 DEG  C. in an inert gas flow. The polycondensates may be dissolved in organic solvents containing hardening agents, applied to conductors and heated at 150-650 DEG  C. to cure them to an insulating coating.  In examples, 2-(benzimidazoyl) benzoic acid and acid lactam forming compounds used are trimellitic anhydride, 3,4-diamino benzoic acid and 3,31-diaminobenzidene. Other reactants are a polyester prepared from ethylene glycol, glycerol and terephthalic acid in the presence of zinc acetate, trimellitic anhydride, diamino diphenyl methane, diphenyl terephthalate, a polyester prepared from ethylene glycol, glycerol, terephthalic acid and naphthalene-2,6-dicarboxylic acid in the presence of zinc acetate, 3,4-diamino-benzoic acid and methyl phenyl terephthalate. The products are dissolved in cresol and transesterified with butyl titanate to introduce titanate groups into them.  The treated solution is diluted with a mixture of cresol, naphtha, xylene, tetralin and pine-base levelling agent to form a wire lacquer.

Abstract: 1517799 Generating combustion products under pressure NISSAN MOTOR CO Ltd 9 Oct 1975 41398/75 Headings FIB, F1G and F1L [ Also in Division F4] The rate of burning of a stoichiometric mixture of hydrogen and oxygen or air, in a combustion chamber 20, Fig. 2, for a turbine 22, an I.C. engine, Fig. 4, or a boiler, is effected by adding gaseous carbon dioxide to the mixture before feeding to the combustion chamber, the carbon dioxide having a heat conductivity lower than that of nitrogen gas. As shown in Fig. 2, carbon dioxide is fed to the mixture under a control 46, responsive to a temperature sensor 42 at the turbine inlet. The hydrogen and oxygen may be burned without diluent initially until the temperature reaches a predetermined level. Again Fig. 4, the addition of carbon dioxide is effected under a control 90 responsive to a combustion sensor 72 responsive to the flame propagation speed in the combustion chamber 66, an ignition spark pulse detector 74, and an engine speed sensor 88. The detector 74 additionally controls feed of the hydrogen and oxygen. The exhaust gas at 68 is fed to a heat exchanger 76 where water is extracted at 80 and the exhaust is recirculated and added to the mixture, so that addition of diluent carbon dioxide may cease.

The respective c.d.'s for the first and second stages are at least 0À5A/cm<SP>2</SP> and not more than 1A/dm<SP>2</SP>, with the second, stage c.d. being lower than the first stage value. The current may be D.C. possibly with periodic reversal thereof or superimposition of A.C. The water may be adjusted to pH 5-7 before treatment; this may be monitored automatically. The two stages may be in a continuous stream, and water separated in stage 1 and/or oil from stage 2 may be recycled. Water flow may be in the same direction in stage 1 as the rising gas bubbles generated by electrolysis and be countercurrent thereto in stage 2. The electrodes may be e.g. Fe, Al or alloys thereof, whereby electrolytic production of their hydroxides assists flocculation of the separated oil. Several cells in parallel may be used in each stage, being independently connectable as required. A complete separation system is described and illustrated. The treatment is stated to discharge ionic emulsion stabilizer whereby the suspended oil of an oil-in-water emulsion is able to separate.
