Title: Improvements in or relating to gas turbine engine power plants
Inventor: DAVIES DAVID OMRI
IPC: F02C9/28
Filed: 1955-05-05
Abstract: 791,062. Gas-turbine plant. ROLLS-ROYCE, Ltd. May 7, 1956 [May 5, 1955], No. 13118/55. Class 110 (3). [Also in Group XXIX] A gas-turbine power plant comprising two or more engines supplied by a common fuel system has, in each engine, at least one temperaturesensitive element disposed in the gas stream downstream of the combustion equipment and common means connected to the temperaturesensitive elements to reduce the fuel flow through the common system when one of the temperature sensitive elements senses a predetermined maximum temperature. Gas turbine jet-propulsion engines 1, 2, 3, 4 are supplied with fuel for a common fuel system consisting of a fuel tank or tanks 9, a booster pump or pumps 10, a high pressure fuel pump or pumps 11 and a fuel line 12. The common fuel supply 12 is controlled by a throttle valve 12a and by varying the stroke of the pump 11. The angle of the swashplate 15 is controlled by a spring- loaded piston 16 the position of which is determined by the flow through the vent pipe 19 in turn controlled by the valve 20. The valve 20 is carried by a pivoted lever 21 which is acted on by an evacuated capsule 25 responsive to the atmospheric pressure, a push-rod 29 loaded by the fuel pressure in the pipe 12 and a spring 30. This arrangement maintains a given fuel pressure for each altitude. The lever 21 is also loaded by a push-rod 34 connected to a Bourdon tube or capsule stack 33 responsive to the pressure in piping 32, which is connected in turn to temperature sensitive elements 31 of the mercury vapour type. When one of the elements 31 senses a predetermined maximum temperature the valve 20 is opened and the fuel supply to all of the engines reduced. The preset maximum temperature may be varied by means of the lever 38. The Bourdon tube or capsule stack 33 may be arranged to increase the fuel supply when the highest temperature falls below the predetermined value. The application of the invention to the fuel system described in Specification 753,474 is also described.- The elements 31 may be located at the outlet of the combustion equipment 6 or when the engine has a multi-stage turbine, in or adjacent to the leading edge of the nozzle guide vanes of a downstream stage or at the outlet of the turbine. The common control means may be a throttle valve in the main fuel line.

Title: Process of and apparatus for crushing, grinding and sifting soft materials
IPC: B02C23/00
Filed: 1934-05-01
Abstract: 424,040. Mills and apparatus. LOESCHE, E. C., 15, Mozartstrasse, Lankwitz, Berlin. May 1, 1934, No. 13159. [Class 59] In a process for crushing, grinding, and sifting soft materials such as grain, pulse, spices, ground nuts, crude potash salts, metalliferous earthy and sandy materials, by means of a mill comprising one or more rollers or the like, coacting with a rotary bed, the mill is actuated intermittently, the finely ground material and the residues being removed alternately by the same air-current. As shown in Fig. 1, one or more rollers c co-operate with a rotating plate b to which material to be ground is fed by means of a device i, each roller being mounted on a pivoted member d acted on by a spring e for adjusting the grinding pressure and by a screw f for regulating the gap between the roller and track. Air admitted through an inlet k lifts the finely-ground particles and passes through a rotating sifting cage j, which rejects the coarser particles, and finally passes through an outlet h to a cyclone separator, for example. Fig. 2 shows a complete plant. In order to grind the materials completely particularly when milling grain, the feed is stopped and the rollers raised periodically, e.g. hydraulically, while the air continues to remove the flour adhering to the particles of bran and carries it through the outlet h and blower l to a cyclone separator m. The bran is then removed to a separator o by shutting-off the outlet h and separator m by flaps r<1>, r2, when the feeding device is restarted and the operation repeats itself. The starting and stopping of the feeding device and reversal of the flaps r<1>, r<2>, may be effected automatically, e.g. by clockwork. The residue in the separator o may be further separated by passing it through a similar plant or through jig-screens. The rollers may be conical and may be driven independently of the plate b, and the smooth or grooved contacting faces of the grinding-members may be of iron, steel, bronze, or stone. The ground material may be dried by heating the air-current or moistened by treating the air with steam or sterilized by adding a disinfectant such as gaseous formaldehyde to the air.

Abstract: 404,524. Electrical musical instruments. LEITHAUSER, G., LIEBAU, M., and WALLOR, H., 1, Heinrich Hertz Institut, 1, Franklinstrasse, Berlin. May 8, 1933, No. 13372. Convention date, Dec. 24, 1932. [Class 88 (ii).] A low-powered oscillating-generating system for use with a separate adjacent wireless receiver 5 in playing music comprises two oscillators 3, 4 and means, such as a note aerial 2 for altering their relative frequency to produce audible notes, the circuit of one oscillator 4 having closely coupled with it a circuit, such as a coil 21, in such a way as to give rise to the phenomenon of " ziehen." The notes are obtained by movement of the player's hand in proximity to the note aerial or metal rod 2, and the presence of " ziehen " causes the notes to correspond to well-separated positions of the hand in space. The coil 21 has a high self-inductance and low self-capacity. The oscillators, which are screened, are doublegrid valves 3, 4 taking their anode voltage from the filament-heating battery. The player's body may serve as aerial for the receiver, his non-performing hand being brought into contact with or close to the plate of a condenser connected with a sheathed aerial lead 10 of the receiver. Complete withdrawal of this hand interrupts the sound in the loudspeaker 6 so that the player may use it for obtaining notes or staccato effects, and as a volume control. A further volume control comprises a hand- or pedal-operated variable condenser, 13 in series or parallel with the aerial and earth terminals of the receiver, or a differential condenser giving a series capacity in one extreme position and a parallel one in the other. An alternative note-switch comprises a valve 16, Fig. 3, in series with the loudspeaker 6 and provided with a filamentswitch 17. The thermal inertial of the filament prevents crackle in the loudspeaker when the switch is operated to sound or stop a note. Fig. 4 shows an oscillator modified to give sound-interruption without crackle. Either or both oscillators 3, 4 are coupled to the note aerial 2 through an additional valve 18, the grid of which may be given a larger negative bias, to interrupt the sound, by closing a switch 19 controlling resistances 20 so proportioned as to give noiseless interruption.
