Title: Improvements in or relating to Turbines.
Inventor: SAYERS WILLIAM BROOKS
Filed: 1908-05-29
Granted: 1909-04-29
Abstract: 11,718. Sayers, W. B. May 29. Gas turbines.-Elastic-fluid turbines are provided with rotors carrying longitudinal vanes co-operating with a series of guide passages in the casing so that motive fluid is caused to act repeatedly upon the rotor while flowing in a generally circumferential course. The guide passages increase progressively in axial dimensions to allow expansive working. Parts of the rotor may act as a turbine while other parts act simultaneously as a centrifugal fan for compressing fluids. In the case of an internalcombustion turbine, the fan part may compress the explosive mixture. A special method of setting and alining the shaft is described. A drum mounted on ball bearings is provided with a number of rows of buckets formed by circumferential and longitudinal ribs on the drum. In the outermost rows the buckets are of double pitch. Fluid is admitted by way of a nozzle j, and after acting on a vane rebounds into a guide passage k, which leads it to a bucket further in advance. The motive fluid continues to flow circumferentially round the rotor by passing into buckets and guide passages alternately until it finally reaches the exhaust. The nozzle j is arranged to coact with the central row a' of buckets, and the succeeding guide passages k increase in width to bring first a row of buckets a<2> into action, then a row a3, and so on, as shown in dotted lines in Fig. 1. More than one nozzle with its co-operating guide passages may be arranged round the periphery of the turbine. Where a single nozzle j is provided, the alining-device shown in Fig. 1 may be fitted. The apertures in the casing for the reception of the stuffing-boxes g have a small clearance, and are provided with adjusting- screws g<2>, by means of which the rotor may be advanced towards the inlet j. In a modification, the stator is provided with a duplicate set of guide passages k<1>, Fig. 3, arranged in a reverse direction, so that part of the apparatus acts as a turbine and part as a centrifugal pump. When used as an internal-combustion turbine, the pump portion is used to compress the explosive mixture. Explosion takes place in the first guide passage, which is fitted with a recess n<1> for the reception of an ignition device, or, alternatively, the ignition device may be situated in a cavity n communicating direct with the buckets. The distance between the delivery port of the pump section and the inlet end of the first guide passage is greater than the distance between adjacent rotor vanes, so that the rotor acts in itself as a cut-off valve for the intermittent supply of explosive mixture.

Title: Improvements in and relating to Wireless Communication
Inventor: FOREST LEE DE
Filed: 1908-09-25
Granted: 1909-03-04
Abstract: 20,206. Forest, L. de. Sept. 25. Wireless telegraphy and telephony; transformers. -In a system of wireless telegraphy or telephony, trains of oscillations in opposite phases are generated in the antenna-system, and signals are given by disturbing the balance of the two trains of oscillations. In the system shown in Fig. 1, the oscillation - system O C P is connected to the antenna-system A<1>, A<2> through the oppositelywound secondaries S', S', thus producing trains of oscillations in opposite phases which normally do not affect the receiving - system b C<1> R nor emit radiation from the antenna-system. The balance is disturbed by the telegraph transmitter or microphone M in one branch of the antenna system. In the modified system shown in Fig. 2, the coils S', S' are wound similarly, and the coils a', a<2> oppositely, so that the effects of the oscillations in the transmitting-system on the receiving-system are balanced as before, and in order that the system may respond to waves from a distant station, inductance a<3> and capacity C<3> are introduced into the two branches of the system so as to throw the oscillations in the coils a', as out of phase. The microphone may be arranged to influence both branches of the antenna-system in the same sense or oppositely, the diaphragm in the latter case being connected to an earthed movable plate immersed in carbon particles between two fixed electrodes connected to the two branches of the antenna-system. In a further modification, a single antenna is used, and the receiving-system is connected to a fourth winding on the transformer P S' S<2> in such a way that it is not affected by normal generation of oscillations. The coils a', a<2> of the receiving-transformer may be wound side-by-side in ring form and pivoted diametrically across the ring forming the coil b, so that the coupling can be readily varied. To prevent inductive action between the receiving and transmitting apparatus at the same station, the receiving-transformer and the whole of the receiving-apparatus may be enclosed in earthed metallic cases or screens.
