Title: An improved method or process for producing motive work from the combustion of fuel and apparatus therefor
IPC: F02C5/06
Filed: 1938-12-30
Abstract: 516,612. Combustion-product plant. NEILSON, A. Dec. 30, 1938, No. 37828. [Class 7(i)) In a power plant in which combustion takes place in an internal-combustion cylinder while the piston or pistons are substantially stationary and the combustion products are conveyed to an expansion engine to perform work, air is compressed in the cylinder to a temperature sufficient to cause ignition of the fuel injected during the combustion period. As shown in Figs. 1, 3, 5 and 13, the combustion cylinder 1 is provided with a main piston 2, actuated from a cam 4 on the shaft 25 through a roller 19 and crosshead 5, and a control piston 3 actuated from eccentrics 8 on the shaft 25 through rods 46 and a crossbar 13. In order to maintain the roller 19 in contact with the cam 4, connecting- rods 48 sliding in brackets 10 on the cylinder 1 are connected to rods 50 carrying rollers 49 travelling in grooves in guide discs 7 on the shaft 25. A rotary blower 27 supplies scavenging air to ports 17 controlled by the piston 2, fuel from pumps 26 is injected through valves 14 during the stationary period of the piston 2, and the products of combustion are delivered through ports 18 controlled by the piston 3 to a receiving chamber 16 connected through a restricted orifice 20, or a loaded valve, pipe 21, valve 76 and conduit 61 to a turbine 30 in which the products perform work. The turbine may be velocity-compounded, with two sets of moving- blades, one on each side of a set of fixed blades. Residual gases escape from the cylinder 1 through a port 67 half the height of port 17. The shaft 25 actuating the pistons 2, 3 may be driven from the turbine 30 directly or through gearing, or may be driven independently by an electric motor or other means. The form of the cam 4 may be modified as indicated at 72, 73 and 77, Fig. 5, to modify the movement of the piston 2. For starting, compressed air from a motor-driven compressor 33 is stored in a receiver 34 and supplied to the turbine 30. The combustion cylinders may be single or double acting and the pistons in a number of combustion cylinders may be connected to one shaft or to separate shafts. The combustion products from a number of cylinders may be discharged successively to the expansion engine or engines, in which simple or multiple expansion may take place. The blower 27 may be dispensed with and air drawn into the cylinder at atmospheric pressure. In a modification, Fig. 17, the control piston 3 is omitted, the cylinder is closed by a cover 69, and the escape of the products of combustion is controlled by a piston-valve 70 actuated by an eccentric on the main shaft.

[Also in Division F2] A quick release coupling has a rod-like retainable portion 19 and a socket-like retainer portion 11 with a tubular abutment member 13 to receive the rod portion 19 extending through it into a recess 12 in which a cup-like piston 16 is movable from a position where its flange 17 surrounds and holds a divided collet 20 in engagement with the part of the rod-like portion which protrudes beyond the member 13 into the recess 12; a frangible member 22 serving to resist displacement of the piston from its holding portion and to determine a minimum pressure on the piston which will displace it and so release the collet and the rod-like portion. Fluid pressure for the release is admitted at 27 to the space behind the piston where a central raised portion 25 and a resilient dished washer 26 maintains pressure of the piston stem 18 on the disc 22. The piston is sealed by an O-ring at 17a. The member 13 may be unscrewed from the portion 11 to reassemble the collets on the rod-portion.

In a break spinning device means to detect the absence of a yarn in the delivery tube 8 is provided and linked to means to stop withdrawal of yarn when such absence occurs so that the broken yarn end remains in the tube above the position of the detection means. As shown photo-electric means 23, 24 are provided to detect yarn absence in tube 8 and a signal therefrom is fed to an amplifier 25 which in turn operates magnetic couplings Ml, M2 to stop the delivery rollers 9 and the fibre feeding rollers 4, 5. In addition a solenoid 16 is energized to displace an armature 17 and thus move a lever 14 pivoted at 13. A yarn guide bar 15 is thus lifted to remove the yarn 7<SP>1</SP> from the grooved driving roll 11 and a sector 20 is pivoted about 19 to brake the wind up spool 10 and lift it clear of the driving roll 11. The lever 14 also operates a counter 26 which thus indicates the number of yarn breaks. A capacative device or a pressure difference device may be used in place of the photo-electric device to detect yarn breaks.

The web portions define a tapered recess 80 and into this recess is pushed a plurality of probes 122, 124, 126, Figs. 1 and 2, having tips which flex the webs apart. The insertion is limited by a stop 188 so that a structurally sound hinge which the apparatus is to test offers resistance to the probes and forces them upwards to make contact 142, 144. Failure to make these contacts actuates a cartridge discarding mechanism. The probes vary in their stressing forces because the hinge offers greater resistance at its centre than at its ends.
