Title: Improvements in or relating to plants for the production of compressed air, for example blast furnace air
IPC: C21B9/08
Filed: 1945-08-08
Abstract: 598,930. Air turbine plant. AKT.- GES. FUR TECHNISCHE STUDIEN. Aug. 8, 1945, Nos. 20319, 20320 and 20321. Convention dates, Aug. 12, 1944, Oct. 14, 1944, and Oct. 26, 1944. [Class 110 (iii)] The invention relates to a plant delivering compressed air to a consumer in which air is compressed in at least one compressor to a maximum pressure which is higher than the pressure necessary for the operation of the consumer plus the pressure drop in the connecting conduits. The plant comprises a compressor and a heater in which part of the compressed air is heated by an indirect supply of heat before being expanded in a turbine driving the compressor. The exhaust of the turbine is partly used as combustion air in the heater and the remaining part of the compressed air is withdrawn from the compressor or in any case not later than before the last stage of the turbine for use in the consumer. The invention consists in heating the compressed air before it enters the consumer. In the plant shown, Fig. 1, the air is compressed in a three-stage compressor 1, 2, 3, -heated indirectly in the heating system 5 of a heater 6 and then expanded in a turbine 9 driving the compressor. A part of the compressed air is withdrawn at the low pressure end of the turbine and passed through the heating system 10 of the heater 6 to the consumer, in this case, a blast furnace 4. In Fig. 2, the air for the consumer is branched off at the outlet of the first stage 12 of the compressor and passes through an independent heater 17. In a modification of this arrangement, the exhaust from the turbine 20 may be used to supply combustion air to the heater 17 and also to supply another consumer of hot air, such as a pre-heater for the fuel. In a further modification, the heater 17 is replaced by one or more pairs of regenerators heated by the blast furnace gas. In all the arrangements, the amount of air supplied for combustion purposes can be at least twice as large as the quantity required for combustion so that slag formation on the heating surfaces is prevented. If desired, the point from which the air for the consumer is withdrawn may be a variable one and the fuel for the heaters blast furnace gas. The amount of air supplied to the consumer may be controlled either (i) varying the amount of intercooling in the compressor ; (ii) by means of byepass pipes and valves on the compressor or turbine ; (iii) by varying the quantity of air compressed to the final pressure ; (iv) by varying the quantity of air expanded in the turbine or the temperature to which this air is heated ; (v) by varying the speed of the turbine-compressor unit or by any combination of these methods.

Title: Improvements relating to means for performing mechanical operations underwater by the use of projectiles
IPC: B63C11/52
Filed: 1922-08-05
Abstract: 205,610. Allan, F. Aug. 5, 1922. Ordnance for submarine discharge ; breech mechanism; sound of f discharge, modifying.-Relates to means for performing mechanical operations under water such as punching holes in steel plates, removing rivets, or causing the penetration of a projectile into and its retention within a steel plate, this being of special utility in salving vessels and other submerged objects. The main features of the invention are (1) a water-tight tube or other medium of low resistance provided in front of the projectile to displace the water which would offer a larger resistance to the projectile, (2) a baffle-plate on the gun to resist the recoil, (3) a spring-controlled recoil cylinder, and (4) an exhaust chamber for receiving the gases from the propellent cartridge to silence the discharge. As shown in Fig. 1, the watertight tube 1 is made in one with the cartridge 3. This tube extends against the plate or into the hole through which the bullet is to be discharged. A soft metal ring 4 or other gas check is provided for the projectile, which for punching holes is a cylinder of hardened steel and for retention in a hole is tapered and serrated and enlarged in the head. The gun, Fig. 3, is mounted within a tubular casing 39 provided with a handle 42 and a recoil-resisting plate 44. The gun can recoil within this casing against a spring 48 in a cvlinder 45 forming the. front end of the casing. Water has access to this cylinder past a flange 47 on the gun, forming a dash-pot checking the recoil. The gases from the cartridge when the projectile is discharged pass through a spring-loaded valve 52, Fig. 2, at the muzzle of the gun barrel into an exhaust chamber 50 and thence escape by another spring-loaded valve 53. A guard 49 is attached to the muzzle of the gun barrel 6. The breech mechanism is of the sliding breech-bolt and striker type. The breech-bolt 15 is provided with a handle 16 guided by a slot in the casing 39, which slot widens out to form a loading aperture 40. A movable cover may he provided for this aperture to exclude sand. When the handle is turned and then pulled back, the bolt lugs 17 are unlocked from recesses 8 in the breech, extractors 23 withdraw the cartridge, and an ejecting lever 38 throws the cartridge out past a spring catch and through the aperture 40. Simultaneously, the striker 25 is retracted about # inch by the cam faces 19, 30. A fresh cartridge is inserted and the breech again closed. During the closing operation, the striker is held back and cocked by the engagement of a pivoted spring catch 28 thereon into a notch 12 in the casing as shown in Fig. 3 The shot is fired by means of a trigger 31 pivoted at 32 and connected bv a wire 33 to a rod 34, which is guided by a block 37 and is controlled by a spring 36. When the trigger is pulled, a cam 35 on the rod 34 wedges the catch 28 out of the recess 12, thereby releasing the striker.
