Title: Improvements in or relating to plants for the generation of gas for use in the production of power
IPC: C10J3/72
Filed: 1943-06-03
Abstract: 568,920. Gas power plant. SULZER FRERES SOC. ANON. June 3, 1943, No. 8894. Convention date, July 2, 1942. [Class 7 (i)] In a power gas generating plant, the piping for the gas is made with double walls 37, 38, Fig. 3, of which the inner wall 37 can expand independently of the outer wall 38, by being connected to it at one end by a bellows 40 or a stuffing-box, for instance, and the space 39 between the walls, which is isolated from the interior of the gas pipe, is filled with air or other gas whose pressure is regulated in accordance with a service pressure of the generator. As shown, a cooling jacket 41 surrounds the outer wall 38 and the inner wall 37 is protected from the hot gases by an inner tube 43 spaced from the wall 37 to provide a chamber to which the gases have access. The generator comprises three free-piston internal-combustion engines 1 ... 3, Fig. 1, each having an inlet 4 for charging and scavenging air and an exhaust outlet 5 leading through an expansion joint 6 to a silencer 7 and the silencers 7 connect with a common piping 9, 12, 13 which feeds the gases to a turbine 10. The air supply is tapped by pipes 14 which conduct a part thereof to the spaces such as 39 in the expansion joints 6, silencers 7, expansion joints 11 and pipe parts 12. The space 39 may form part of a circuit, including a cooler and a circulating pump.

Title: Jet propulsion engine exhaust silencers
IPC: F02K1/56
Filed: 1957-03-19
Abstract: 823,302. Jet propulsion engines. UNITED AIRCRAFT CORPORATION. March 19, 1957 [March 29, 1956], No. 8958/57. Class 110 (3). [Also in Group XXXIII] An exhaust silencer for a jet propulsion engine exhaust duct through which the gas flow is not of a pulsating nature comprises one or more hollow vanes projecting outwardly from the exhaust duct, each vane having a plurality of small openings through which the exhaust gas from the duct may exhaust. The exhaust gases chamber 46 in an exhaust duct 38 from which they are diverted by means of a conical bulkhead 45 into hollow vanes 44 each of which has a plurality of small nozzles 48 on its trailing edge. The vanes 44 may be made of sheet metal and provided with bulkheads 71 to stiffen, space and support the walls of the vanes. Turning vanes 73 may be used to direct the gas flow into the vane. In a modification. Fig. 8, the vanes 44 are pivoted on the exhaust duct 20. These vanes are moved between the retracted position shown and an operative position in which they project radially outwards by jacks 80. Jacks 96 are provided to retract a portion 94 of a cowling 92 when the vanes are in their operative position. Flaps 86 integral with the vanes block passages in the wall of the exhaust duct 20 when the vanes are in the inoperative position. When the vanes are in the operative position, these flaps blank off the outlet from the exhaust passage. The vanes may be locked in the operative position by means of a ring, Fig. 12 (not shown), which carries a number of locking arms arranged to engage holes in lugs attached respectively to the flap and exhaust duct. In a further modification, Fig. 13, each vane is provided with a central partition 120 and a flap valve 122 which may be used to divert the gases to one side or the other of the partition so that the gas may flow out of either the forwardly directed nozzles 124 or the rearwardly directed nozzles 48.

Title: Improvements in variable electric resistances
IPC: G03C7/10
Filed: 1925-04-03
Abstract: 253,648. British Thomson-Houston Co., Ltd., Harris, P. T., and Stace, A. T. April 3, 1925. Sets of resistances, variable resistances.-Variable resistances of the type having two or more resistance coils of different values used separately in connection with a single moving contact finger are so arranged that the contact finger cannot be inadvertently moved from one coil to the other while rotating the spindle which carries it. When the finger is moved from one coil to the other by a longitudinal movement of the spindle a gate device is provided which only allows the finger to move from one coil to the other when it is in the " off " position. This gate device may consist of a longitudinal groove 15<1> in the spindle 12, Fig. 2, connecting two circumferential grooves 15. A spring plunger 16 engages with the grooves 15 and passes from one to another of them through the groove 15' when the spindle 12 is moved from one to the other of the resistance coils 9 by the knob 17, which is connected to the ordinary knob 14 so as to rotate therewith by a pin 18. The gate device mav also be formed in the edge of the knob 14 and engage with a fixed pointer. In a modification shown in Fig. 1 the spindle 3 has no axial movement and the resistance coils 1, 2 are mounted on a pivoted link 5 so that either of them can be brought into the path of the contact finger 4 by means of operating links 6.
