Patent GB-277957-A (GB)
Title: A method of, and apparatus for, generating streams of gas by combustion
IPC: F24C1/00
Filed: 1927-09-13
Abstract: 277,957. Jezler, H. Sept. 23, 1926, [Convention date]. Generating combustion products under pressure.-A stream of gas for power purposes is. generated by successive explosions in a plurality of combustion chambers 1 which exhaust into a common conduit 3 to which air is admitted in such a manner that it meets the entering jets of exhaust gas and is deflected thereby into the chamber or chambers in which no explosion is occurring. These chambers are thus filled with compressed mixed air and combustion gases at a temperature above the ignition point of finely atomized fuel which is then sprayed into the chambers and ignites. By rapidly following explosions a continuous stream of gas is obtained which can be used in turbines, reciprocating engines and for jet propulsion. The combustion chambers 1, Fig. 1, are disposed around a central tube 3 with which they are connected at one end by nozzles 2. Tubes 4 lead from the other ends of the combustion chambers to an annular nozzle 5 forming an injector for sucking in and compressing air. Below the nozzles 2 is an enlargement 7 of the main nozzle 8. The cone of jets from the nozzles 2 forms at 10 an obstruction in the central tube so that the mixed air and gas combustion products flowing in the direction of the arrow 9 are compelled to change their direction and flow through the nozzles 2 of the chambers in which combustion is not taking place, as shown by the arrow 11, expelling the burnt gases through the tubes 4 and annular nozzles 5. For spraying the fuel the combustion chambers are connected bv tubes of small diameter into each of which opens a fuel conduit connected with a pump. When combustion is taking place in one chamber the next chamber is under compression so that hot products of combustion flow from the first chamber to the second, causing atomization and ignition. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a form in which the combustion gases issue from a number of combustion chambers 4, Fig. 3 (Cancelled), through pairs of nozzles 2, 3 arranged on the outer and inner periphery of an annular tube 1, the main part of the gas passing through a nozzle 5 for use. The rest of the gas flows through a nozzle 6 into the flared open end 7 of the tube 1 whereby air is sucked into the system and compressed, the stream of mixed air and combustion products flowing in the direction of the arrow I past the openings of the nozzles 2, 3. A portion of the gas passes into the outer nozzles 2 of those ccmbustion chambers in which combustion is not taking place, expelling the residual products of combustion through the inner nozzles 3 and filing the chambers with compressed mixed air and combustion products at a temperature above the ignition point of the fuel which is then injected and ignites, the combustion gases passing through both inner and outer nozzles at high velocity. This subject-matter does not appear in the Specification as accepted.

Abstract: In a drawing frame e.g. for doubling and drafting cotton and sliver, the rolls of each pair of hard-surfaced, high-speed, adjustably spring-loaded drafting rolls are fluted, both the flutes and the intervening valleys are radiussed and so formed that the cross-sectional profile of the roll surface is smoothly curved, and the radii of curvature of the flutes and valleys are equal to or greater than the spacing of the tips of the flutes and the bottom of the valleys from the pitch line of the roll.  Each flute and valley of each roll of a pair lies respectively on a helix coaxial with the roll, the helices of the two rolls of each pair are of equal pitch angle but of opposite hand, and the flutes and valleys loosely intermesh.  The difference between the valley portion radius of curvature and the flute tip radius of curvature of the pairs of rolls decreases from the back rolls to the front rolls in correspondence with the thickness of the fibre mass passing between successive pairs of rolls and approximately according to the draft ratio therebetween. The fluted rolls also apply a crushing or "purifying" pressure on the fibres simultaneously with drafting and without loss of control thereof.
