Patent GB-2090479-A (GB)
Title: Asynchronous electric machines and rotors therefor
IPC: H02K17/16
Filed: 1981-12-17
Abstract: A rotor (3), e.g. a squirrel-cage rotor, for an asynchronous electric machine has one or more conductive bodies (7, 8) supported for rotation with the rotor within the stray magnetic field which exists in the space between one or both ends or short-circuit rings (5) of the rotor winding and the protruding stator end windings (2) of the machine. The conductive bodies (7, 8) which are most conveniently in the form of rings or discs, may be either of magnetizable or non-magnetizable material or a combination of both. The conductive body may be a blower (Fig. 8, not shown). The increased losses which arise in the conductive bodies in operation serve to increase the starting torque of the machine. <IMAGE>

Patent GB-2116699-A (GB)
Title: Fluid flowmeter
Inventor: PITT GILLIES DAVID
IPC: G01F1/704
Filed: 1982-03-02
Abstract: The velocity of a fluid flowing in a stream through a pipe (16) for example, is determined from calculations of the phase-angle difference ( theta ) for different frequency values (f) between two spaced apart signals modulated in dependence on the flow velocity by, for example, transmission through the fluid to detector means, such as detectors 14 and 15. The slope of the phase- angle curve is related to the transit time of a particular disturbance in the flow between the two signals, hence the flow velocity. The signals may be optical signals provided by a laser source or an incandescent lamp; the latter having an improved signal to noise ratio than the former and requiring less electronics to perform the calculation of flow velocity. The electronics may include a microprocessor and a fast Fourier transformer. The method may be used to determine average flow velocity in a stream as in a fluid flowmeter, or to determine the flow velocity at a particular point in the flow for flow turbulence studies. <IMAGE>

Title: Low temperature reduction process for photomasks
Inventor: ERNSBERGER FRED MARTIN
IPC: G03F1/54
Filed: 1984-11-21
Abstract: Glass photomasks having a high resolution stain pattern with a roll off or the pattern edge of one micron or less are made by migrating stain-producing ions into the surface of a glass substrate, and reducing and agglomerating the stain-producing ions in the presence of pure hydrogen under pressure at relatively low temperatures to produce a high resolution stain pattern. To prepare large glass photomasks the reduction is carried out by heating the mask in an inert liquid saturated with hydrogen under pressure.

Title: A tippermeter
Inventor: WARREN ROY KENNETH
IPC: G01R33/028
Filed: 1984-12-17
Abstract: A measurement apparatus which is used in determining the angle which the earth's total electromagnetic field vector makes with the horizontal plane tangent to the surface of the earth at a given location, which angle is known as the "tipper". The apparatus may be used for reconnaissance surveys by taking measurements along roads and other public areas to determine locations of high "tipper" that in turn relate to subsurface features which may indicate the presence of hydrocarbon deposits. The apparatus includes two detecting coils 11a, 11b which are mounted at right angles in the shape of an inverted tee. The coils are designed so as to be sensitive to changes of as little as 0.01 gammas in the earth's electromagnetic field at a frequency of 8 Hz. Electronic circuits having a special transfer function are provided to amplify the signals from the coils. The amplified signals are converted to dc pulses which are stored in output capacitors for readout with a voltmeter. <IMAGE>

The lid has one or more holes 10 in it and these permit the liquid to pass from the cavity into the space between the lid and the diaphragm. The support reduces vibrations of high-frequency and low-amplitude and damps those of low-frequency and high-amplitude. <IMAGE>

Title: Process and plant for deodorising and/or physical refining of high-boiling liquids
Inventor: STAGE DR HERMANN
IPC: B01D3/38
Filed: 1985-09-11
Abstract: The deodorizing and/or physical refining of high-boiling liquids such as edible oils, fats, glycerides and other high-boiling esters as well as fatty acids takes place at a working pressure of less than 10 mbar at a liquid temperature of 180 to 280 DEG C. For a significant increase in the liquid throughput under these working conditions in conventional plants equipped with plate columns or the like without a simultaneous increase in the quantity of stripping steam and/or the capital investment and operating cost of the vacuum unit, the steam once utilized as stripping steam in the one or "old" plant part 10, after cooling and substantial removal of volatile matter, is again introduced as stripping steam into another, "new" plant part 30 and used therein for stripping volatile matter from already pretreated or from untreated liquid, whereupon it is again cooled, substantially freed from volatile matter and fed to the vacuum unit. Because of the low pressure loss, a single-stage or multi-stage falling-film column is especially provided as the other or "new" plant part. <IMAGE>
