Title: Engine fuel combustion process - fuel compressed isothermally by piston releasing thermal impulses to start combustion
IPC: F02B3/00
Filed: 1968-11-06
Granted: 1975-02-28
Abstract: An I.C. engine, particularly a rotary piston engine, uses the energy in the fuel by compressing a mixture of air and liquid or gaseous fuel, or by compressing air only and injecting fuel. Compression is effected isothermally by piston, releasing a thermal impulse starting combustion. This develops in an isobaric and isochoric manner, with 20% maximum after-burning, at a pressure from 45 to 68 atmospheres. The indicator diagram is completed by the isothermal expansion characteristic, the mean pressure reaching 14 to 25 atmospheres depending on the heat transfer, as the result of the low energy requirement during compression and better utilisation of the fuel calorific value.

Abstract: 444,103. Regulating the flow of gaseous fluids. BABCOCK & WILCOX, Ltd., and DAVY, C. H., Babcock House, Farringdon Street, London. Jan. 13, 1936, No. 1116. [Class 135] A method of regulating the volume of flow of a gaseous fluid in a conduit 1 consists in projecting one or more secondary streams of gaseous fluid at a higher pressure across the main stream in the conduit 1 through a nozzle or nozzles 2. The secondary fluid may be supplied under pressure by a fan 3 from a separate source or from a point downstream in the main conduit 1 or from the exhaust side of a fan drawing the gaseous fluid through the conduit 1. The supply from the fan 3 is regulated to control the secondary streams of fluid and therefore the effective free area of flow through the conduit 1. The invention may be used in the control of heating gases in heat-exchangers and the control of air in ventilating shafts in buildings and mines.

Filed: 1951-01-17
Abstract: The invention comprises compounds having the general formula <FORM:0721742/IV (b)/1> wherein A represents a hydroxyl radical or an N-aliphatic-a -amino acid residue, and a process for the preparation of the above compounds by reducing 4 - ([(2 - amino - 4 - hydroxy - 6 - pteridyl) methyl]-formylamino) benzoic acid or an amide thereof derived from an aliphatic-a -amino acid in aqueous solution at a pH between approximately 3 and 9 until 2 mols of hydrogen are introduced into the molecule of the substituted benzoic acid or amide thereof. The reduction may be effected with hydrogen and a hydrogenation catalyst, e.g. platinum oxide, Raney nickel or palladium black, with hydrogen generated electrolytically in the solution or with a mild chemical reducing agent, e.g. sodium hydrosulphite, at room or elevated temperatures.  An increase in the yield of the desired compounds is obtained if the reduction is carried out in the presence of ammonium ion, or by heating or autoclaving the final reaction mixture, or by allowing the reaction mixture to stand at room temperature or lower temperatures for prolonged periods.  The preferred compounds of the above general formula are those having an ability to reverse methyl folic acid inhibition in Lactobacillus casei and Streptococcus fecalis and an ability to stimulate maximal growth of Leuconostoc citrovorum 8081 in a growth deficient medium. Suitable formylpteroyl compounds which may be used in the above process are formylpteroic acid, formylpteroyl glutamic acid and formylpteroyl compounds containing a plurality of glutamyl groups such as formylpteroyl di-, tri- and hepta-(a -glutamyl) glutamic acid.  In the examples the following compounds are prepared: 5 - formyl - 5,6,7,8 - tetrahydropteroyl glutamic acid, 5 - formyl - 5,6,7,8 - tetrahydropteroic acid, 5 - formyl - 5,6,7,8 - tetrahydropteroyl - a  - glutamyl-glutamic acid and 5-formyl-5,6,7,8-tetrahydropteroyl - di - (a  - glutanyl) - glutamic acid.  Formylpteroic acid, formylpteroylglutamic acid and formylpteroyl mono- and poly-(a -glutamyl) glutamic acid are prepared by heating the required pteroyl compound with formic acid and acetic anhydride and removing excess reagents in vacuo.

Abstract: 591,113. Generating combustion products under pressure. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and FEILDEN, G.B.R. Jan. 16, 1945, No. 1354. [Class 51 (i)] [Also in Groups XI and XXVI] A combustion apparatus, particularly for a gas turbine plant, in which the fuel is injected in a downstream direction into a flame chamber enclosed within an air duct, has the fuel injector burner, which supports the upstream end of the flame chamber detachably mounted on a structural member of the air duct which lies in and divides the air stream and through which pass the fuel supply connections to the burner. The flame chamber is attached to the burner by releasable locking means which allows its easy withdrawal in the axial direction. A burner 5 is mounted on the downstream edge of a structural member 7 of aerofoil form in cross-section which lies in and divides the airstream so as to be removable therefrom without disturbing the fuel supply connections. The burner, which is of the. spill controlled type, receives fuel from an inlet connection 10 through axial passages 11 each of which is fitted with a tubular liner 12. The liners 12 project from each end of the member 7 and are fitted with sealing rings 14 and 16 so as to make a fluid tight joint when the bolts attaching the inlet connection 10 and the burner 5 to the member 7 are tightened up. The burner 5 supports the upstream end of the flame chamber 4 by means of a screwed sleeve 24 engaged by a locking sleeve 25. The burner nozzle 20 is formed in a separate end plate held in position on the burner by a screwed sleeve 22. The radial passage 8 not only accommodates the fuel inlet connection but also forms a passage for cooling air for the bearings and shaft. A modification using a single duct burner is also described.

The powder 13 is fluidised by passing air; preferably heated to 20-35‹C, upwards through the floor 12 by means of a fan 14. The powder 13 may be replenished from a vibrating screen 21 and the coated granules which float to the surface are collected via outlet 22. The perforated floor 12 may be tilted or a transverse flow of air may be blown across the fluidised bed to assist the removal of the coated granules. A nozzle plate or nozzle battery may be used in place of the perforated floor 12. The process may also be carried out using a cloud of flue dust in place of a fluidised bed. Binding slabs are made of concrete incorporating the coated granules of polyurethane.
