Title: Reciprocating stratified charge internal combustion engine and mixture formation process
IPC: F02M69/00
Filed: 1973-03-02
Abstract: 1369969 Stratified charge combustion chamber G STAHL 2 March 1973 10656/73 Heading F1B An I.C. engine having means to form a  stratified charge comprises a cylinder head with an "intake section" and an "exhaust section" forming the combustion chamber, an intake valve and spark plug in the intake section and an exhaust valve in the exhaust section, the cylinder head being shaped to form a flow restriction between the two sections. The combustion chamber has an intake section 2, in which the inlet valve 4 and the spark plug 6 are situated. A low pressure petrol injection nozzle 7 is located in the inlet passage. The exhaust valve 5 is situated in an exhaust section 3 and has its stem coaxial with the cylinder. A duct 8 is provided for heating the intake section. With the combustion chamber shape shown in Fig. 1a the engine can operate throughout the load range with 140% excess air over the stoichiometric quantity, control being exercised by varying the mixture strength. Fuel injection commences not earlier than half way through the induction stroke and terminates at the end of the same stroke, so that at the end of the compression stroke, the intake section contains a rich mixture and the exhaust section a lean mixture. The strength of the lean mixture can be varied by continuing injection of fuel after the inlet valve has closed, so that fuel accumulates upstream of inlet valve and is drawn into the exhuast section at the beginning of the next suction stroke. Air-fuel ratios of 1À25 to 1À35 times the stoichiometric value produce a satisfactory reduction in the quantities of carbon monoxide and nitrogen dioxides and these ratios can be achieved in an engine in which the intake section 2 is moved nearer to the cylinder axis. The principle may be used on a 2-stroke engine with through-flow scavenging.

Title: Position indicating device
IPC: G05B19/33
Filed: 1964-03-13
Abstract: 1,044,055. Electric selective signalling. GENERAL ELECTRIC CO. March 13, 1964 [March 14, 1963], No. 10805/64. Heading G4H. In a system for controlling the position of an object, e.g. part of a machine tool, of the kind in which a number of position indicating devices produce recurring, phase-disposed feed-back signals representing, in different denominations, the position of the object and counters controlled by the feed-back signals to give a numerical indication of the object position. The system has coarse, medium and fine control loops. Command signals from input 10, Fig. 1 (not shown); set counters 14, 15, 16, reference clock pulses (250 kes.) being applied to the counters to obtain phase displaced signals representative of the numbers in the counters. These are applied to comparators 17, 18, 19, the outputs of which are combined in converter 28 to produce a signal controlling a servomotor 29 driving the object positioning mechanism. The servo shaft is connected to a fine resolver 25 and through gearing 27 and 26 to medium and coarse resolvers 24, 23. These are supplied with reference sine and cosine waves from generator 13 which receives reference clock pulses at 250 cycles per second from counter. The outputs of the resolvers are applied shapers 20, 21, 22, each making a train of pulses phase displaced according to the position of the object. These are applied to comparators 17, 18, 19 for comparison with the input signals. The difference signal drives the servo to reduce the difference to zero. The inputs to the comparators are in the form of a differentially timed pulse for each 1000 cycles from generator 11 constituting a phase displaced recurrent pulse train. The outputs from the shapes 20, 21, 22 are applied to control the coarse, medium and fine counters. The reference counter 12 produces signals at predetermined counts. These are gated together and used to enable the medium, coarse and fine counters successively immediately before the beginning of each 1000 pulse cycle, Fig. 4 (not shown). When the corresponding differentially timed pulse occurs the counter counts the reference clock pulses until it is disabled again slightly before the beginning of the next cycle. At the end of each cycle the counters contain numbers representing in binary-coded decimal the position of the object, the values in the medium and coarse counters, since these were stopped before the end of the cycle (Fig. 4) being too small by amounts 15 and 25. These values are corrected by comparing the top decade of the fine counter with the lowest decade of the medium counter and comparing the top decade of the medium counter with the lowest decade of the coarse counter. If the values compared are different the decade belonging to the higher significance counter is corrected so that the medium and coarse counters finally indicate a position which incorporates the value in the fine counter. The final values may be visually displayed in decimal form and recorded for later use.

Title: A process for the gasification of fine-grained and like fuels
IPC: C10B49/16
Filed: 1951-05-09
Abstract: 744,742. Iron manufacture. WEBER, L. May 9, 1951 [May 11, 1950], No. 10969/51. Class 72. [Also in Group XII] Fuels either fine-grained or in the form of small lumps are gasified in one or more stages by intimate and moving contact effected by means within the furnace with a granular ore serving as a heat carrier heated in a separate furnace to above the gasification temperature and separated from any fuel residues at the end of the stage or stages by means utilizing the different physical properties of the residues. As heat carrier solids iron, heavy metals, or ores or oxides or ceramic masses in which e.g. metal oxides may be embedded, may be used, preferably with rough or porous surfaces or catalytic effect and readily separable from the fuel residues. The gases generated may be utilized for smelting, particularly for obtaining iron sponge, crude iron or steel, the ore being passed directly to the smelting furnace after use as heat carrier in generating the gases. For gasifying lumpy fuels in a shaft furnace 1 by means of steam injected through an inlet 5 fine-grained heat carrier material is introduced at the top and sifted off at the bottom through an inclined grate 2, unconsumed fuel being controllably removed past a slide 4 e.g. to a boiler furnace 10. The raw fuel may be coked in a rotating cylinder 8 by contact with the heat carrier material before this is returned to a heater 9. For gasifying finer fuels, e.g. peat, brown coal or lignite up to 10 mm. or pit coal up to 3 mm., a substantially horizontal rotating furnace may be employed having internal helical grooves, &c. by means of which the heat carrier fed in at one end is carried forward, repeatedly falling as a dense rain through a blast of steam and fuel introduced at the other end. In another embodiment dust fuel is suspended in a chamber into which the heat carrier is passed from above. Heavy hydrocarbons may be introduced with the fuel to produce a carburetted gas.
