Patent GB-917586-A (GB)
Abstract: 917,586. Rotor balancing. LOSENHAUSENWERK, DUSSELDORFER MASCHINENBAU A.G. Dec. 7, 1959 [Jan. 9, 1959], No. 41443/59. Class 40 (1). [Also in Group XIX] In a rotor balancing machine, the body to be balanced is driven until its speed is higher than that producing resonant vibrations, the drive is then uncoupled and, by means of a speedmeasuring device, the indicating instrument is clamped when the speed has dropped to the resonant value. In the Figure the body 1 is rotated by a motor 2 through a clutch 3 which is disengaged when the speed has risen above the resonance value. The unbalance vibrations are sensed by a barium titanate transducer 4 and applied to a phase-sensitive detector 6 in conjunction with pulses from a multi-vibrator 11 which is triggered by a photo-transistor 10 scanning reference marks on the rotor. The detector output is passed to an indicator 7. The pulses from the photo-transistor are also fed to a meter 13 whose deflection is proportional to the instantaneous speed of the body. At a certain speed, which is arranged to be that at which resonance vibrations occur in the rotor, a contact 14 closes and energizes an electromagnet 15 to clamp the indication of the meter 7 and any other meters provided. The phasesensitive detector can be replaced by a bi-stable multivibrator which is triggered by the pulses from the photo-transistor. Unbalance at 90 degrees to the first can be measured with another transducer 4<SP>1</SP> with a separate detector. If the unbalance is to be measured in planes other than the bearing planes the transducers are connected in opposition through potential dividers adjusted in accordance with the distances between the measuring planes and the bearing planes.

Title: Air flow generating apparatus
Inventor: STRATFORD BRIAN STAPLETON
IPC: F03G6/04
Filed: 1992-11-20
Abstract: Apparatus for generating an air flow comprising a duct 1 (which could be in the form of a tower) which rises to a substantial height, e.g. 10 to 17 km. Means are provided for providing warm air for passage up the duct, which may include the provision of a large transparent roof over the ground surrounding the duct to heat the air beneath the roof by solar heating. For this purpose the roof may include water-filled solar panels connected to the heat exchangers 5. The warm air in the duct rises to a height at which moisture may condense therefrom thus creating a further driving force for the air flow through the duct. The air flow into the duct through inlets 4 and the exchangers 5 may be used to drive turbines 6 for the generation of electricity. Further air inlets 7 are provided in the side of the tower. The apparatus simulates hurricanes by the removal of solar heat from the ground and the transport of this heat to a high altitude. The removal of ground solar heating in an area prone to hurricanes may thus prevent natural hurricanes occurring. <IMAGE>

Abstract: 927,660. Furnaces for treating fluidizable materials. BADISCHE ANILIN- & SODAFABRIK A.G. Sept. 1, 1961 [Sept. 3, 1960], No. 31511/61. Classes 51 (1) and 51 (2). To decrease the discharge of dust from a fluidized bed furnace, an insertion is provided which overlies the bed substantially completely, and which defines with the walls of the furnace an opening for the gases which has a cross-sectional area greater than that of the bed. As shown in Fig. 1, the insert 112 is of ceramic material, and sits on an annular ring of water pipes 110 having inlet and outlet pipes 111. The furnace walls are lined with cooling pipes 106 running between top and bottom headers 106a and 106b, over a refractory lining 107. The gas is supplied through a pipe 103 and a windbox 104 and after passing through the bed 101 is slowed by the larger area of the stilling chamber, and then speeds up as the chamber constricts towards the vent 113. As shown in Fig. 2, the temperature of the bed is regulated by a pipe 206. The cooling pipes 202 run horizontally round the furnace, and form a constriction above the insert 208, which consists of an annular ring of pipes with a hole 209 in the centre through which material can return to the bed. Above the constriction is a nest of pipes 211 forming part of a conventional steam boiler. As shown in Fig. 3, the fluidized bed 301 is of square crosssection, but the furnace chamber above is of circular cross-section. The insert is formed of a spiral of pipes above a rammed refractory mix which reflects heat back down to the bed. Pipes 307, 308 are provided with tangential nozzles which blow air into the furnace, causing a vortex in the stilling chamber, which helps to deposit the particles from the gases on to the peripheral walls.

Title: Detecting diamonds in a plurality of objects
Inventor: SMITH MARTIN PHILLIP
IPC: B07C5/342
Filed: 1992-02-20
Abstract: To detect diamonds in a plurality of objects 1, eg for sorting ore before it is fed to size reducing means, the objects are irradiated with infrared radiation, and radiation from the objects is passed through a narrow bandpass filter which passes radiation shifted by an amount corresponding to the Raman shift for diamond. A sensor 9 receives the radiation passing through the filter, and the radiation intensity signal from the sensor 9 is corrected using a signal from sensor 8 dependent on the size of the objects. The objects are then sorted into categories A to E according to their corrected Raman signal levels. Radiation from a laser 10 may be focused into a non-vertical line lying in a vertical plane containing the trajectories of the objects so that some radiation is Raman scattered back to sensor 9 and also each object casts a shadow on detector 8. <IMAGE>
