Title: Improvements relating to the air cooling of gas turbines
IPC: F02C7/18
Filed: 1954-03-29
Abstract: 754.856. Gas turbine plant. DAIMLERBENZ AKT.-GES. March 29, 1954 [March 27, 1953], No. 9136/54. Class 110(3) In a gas turbine plant, air is branched from the combustion air supply then caused to pass through enclosed circuits, including ducts in the stator and rotor blades, in parallel with the combustion air flow and then finally mixed with the combustion air to complement the latter in supporting combustion. Air compressed in the compressor 14 is heated in the heatexchanger 19 by the turbine exhaust gases and then passed into a combustion chamber 21 feeding a gas turbine 16 driving the compressor. A part of the air compressed in the compressor 14 is passed through the cooler 28 and then further compressed in a compressor 26 driven from the turbine shaft. The discharge of the compressor 26 passes through a dust separator 30 into a conduit 29 which branches into conduits 31, 32. The conduit 31 passes into the turbine casing where the cooling air is caused to pass through annular spaces 33 and U-shaped passages 34 in the guide blades to a conduit 35 leading through a change-over valve 36 and a conduit 37 into the main air or gas pipe 20 leading to the turbine 16. The conduit 32 is connected through a changeover valve 38 to a conduit 39 which is in turn connected to a bore 40 in the turbine shaft and to the change-over valve 36. The bore 40 is connected through U-shaped cooling air passages 41, 43 in the rotor blades and passages 42, 44 to a conduit 45 which leads to cooling passages 47 in the compressor inlet guide blades and thence to a conduit 49 to the main air or gas pipe 20. A change-over or short-circuit valve may be provided at the point 50 to by-pass the compressor inlet guide blades. In the position of the change-over valves 36, 38 shown, the cooling air is passed through the stator and rotor blades in series. By changing over the valves, the circuits through the stator and rotor blades may be arranged in parallel. One or more intermediate coolers for the cooling air may be provided between the parts of the turbine to be cooled.

Abstract: 164,891. Coo, T. J. March 29, 1920. Guarding against unauthorized use.- Locking-devices arranged inside the bonnet and operated from the interior of the car comprise means for locking the bonnet closed, a permutation lock which controls the bonnet locks and an ignition switch; an audible signal is operated if the brake is released where the ignition circuit is open. Figs. 1 and 2 show a general view of the apparatus and Fig. 5 an elevation of the part of the mechanism arranged on the back of the plate 1 which is secured to the forward side of the rear wall 3 of the engine compartment. The bonnet-locking devices comprise sliding latches 39, Fig. 4, arranged in casings 34, forced into locking position by springs 40 and withdrawn by wires connected to a drum 21 which can be rotated from the driver's seat by a knob 27. The rotation of the drum is controlled by means of a two-armed lever 22 which co-operates with a two-armed lever 16 connected by a pin-and-slot connection 15, 18 to the sliding bolt 13 of the permutation lock, which is also controlled from the driver's seat through the jointed shaft 6. The bolt 13 also operates the ignition switch 10, 11 by an insulated link 12. When the ignition switch is open, the bolt 13 moves the lever 16 into the position shown in full lines in Fig. 5 against the spring 28, and the lever 22 is thus locked in either of the two positions shown so that the bonnet locks are held either in or out, the fullline position being that corresponding to a locked bonnet. When the ignition switch is closed, the bolt 13 moves the lever 16 into the position shown in dotted lines. The lever 22 can then be turned into the unlocked bonnet position shown in dotted lines and retained there bv means of the shoulder 20 on the lever 16. The bolt 13 also operates a switch consisting of a fixed arm 50 and a movable spring arm 51 so as to close the circuit of an electric horn when the ignition switch is open, unless the brake lever 54 is in the " on " position when a wire connection 52 acting as a compression member working in a tubular casing raises the spring arm 51. The car cannot therefore be towed or moved without sounding the horn. Locking devices similar to those used for the bonnet may be applied to other parts of the vehicle such as the clutch, gearing or spare wheel or rim, similar wire and tube connections to the permutation lock being provided.
