Title: Method and apparatus for detecting stator faults in rotary dynamoelectric machines
Inventor: SEDDING HOWARD G
IPC: G01R31/34
Filed: 1993-01-04
Abstract: In order to determine the occurrence of a stator fault in an induction motor during operation of the motor, the axial leakage flux is monitored during operation of the motor. The occurrence of a stator fault is detected by observing a change in selected harmonic components of the axial leakage. The angular position of the fault with respect to a datum position is determined by noting and recording changes in the axial leakage flux at a plurality of positions distributed symmetrically around the axis of the motor and computing the angular position by triangulation. The axial leakage flux is detected by individual search coils located at said plurality of positions. <IMAGE>

Abstract: COMPUTER GRAPHICS DISPLAY METHOD AND               SYSTEM WITH SHADOW GENERATION                            Abstract A computer graphics display system and method are described for  rendering  a  scene  formed of  at  least one  geometric primitive as a pixel image having shadows produced by at least one defined light source.  Multiple passes are made through the primitive data structure for each light source capable of producing shadows in the scene to be rendered. In a first pass, the scene is rendered to a frame buffer in the usual way, but using only the ambient component of the light specification,  and a first Z-buffer is updated with the viewpoint Z value.  For each defined light source (i), two  additional passes  (PASS 2i & 2i+1) through the data structure  are  required.    In  the  first  of  these,   a transformation matrix is  set up in such a way that the viewpoint is moved to the position of the light source.  The scene is then rendered in the usual way except that the frame buffer is not updated,  and a second Z-buffer (light source view Z-buffer) is used instead of the first Z-buffer. In the next pass, the shaded image and shadows are generated in parallel  using  the  content  of  the  first  and  second Z-buffers.   When  the  frame  buffer  is  updated,  it  is accomplished  in  a  cumulative  manner  with  each  computed intensity value due to a specific light source being added to any value already stored there.  In this way, intensities resultant  from  each  of  multiple   light  sources   are accumulated on the image.

Inventor: DAVIES PETER
IPC: B09B1/00
Filed: 1993-02-23
Abstract: A method of treating mineral tailings such as those derived from mining operations includes the steps of separating the slimes, forming alternate layers of slimes and a coarse material between peripheral berms and intermediate berms, the berms being of a coarse material, and allowing water to pass therethrough and away from the berms. The water moves through the berms by virtue of the pressure exerted on the lower layers by the mass of the layers above. The coarse material may be the coarse fraction of the mineral tailings.

Abstract: Novel alkylenediammonium diclavulanate derivatives, process for the preparaiton thereof and use thereof.    A novel process for the preparation of calvulanic acid and pharmaceutically acceptable salts thereof, such as potassium clavulanate, is described.  According to the novel process, crude clavulanic acid is reacted with substituted alkylenediamines of the formula   wherein the substituents R1, R2, R3 and R4 denote - a hydrogen atom, - a straight-chain or branched-chain alkyl group having 1 to 8 carbon atoms or - a hydroxyalkyl group having 2 to 4 carbon atoms and NR1R2 and/or NR3R4 jointly denote a heterocylic ring having 3 to 6 methylene groups bound to a nitrogen atom, one of these groups being optionally substituted by an oxygen or a sulphur atom or by an imino group and R5 denotes a hydrogen atom, or a methyl group and n denotes an integer from 1 to 3, to produce novel alkylenediammonium diclavulanates of the formula   The obtained compounds are optionally isolated and converted with alkali alkanoates, such as potassium 2-ethylhexanoate in isopropanol, to potassium clavulanate. Because of their high inhibitory action against beta-lactamases and because of a significant synergistic action in combination with the beta-lactam antibiotics from the group of penicillins and cephalosporins, clavulanic acid and pharmaceutically acceptable salts thereof are valuable compounds for the preparation of galenic compositions, which are active in the treatment of infectious diseases induced by numerous gram-positive and gram-negative microorganisms.

Abstract: A rotary disc filtration device having a fluid filtration gap between a filtration surface and a disc is disclosed. The disc and/or filter has one or more spiral grooves in fluid communication with fluid in the gap. The disc and/or filter is rotated and one or both may be axially oscillated and/or vibrated to create the shear at the filter surface that increases permeate flux through the filter. Several discs and filters may be interleaved to increase filtration device capacity and make more efficient use of equipment space.

Filed: 1993-11-25
Abstract: A method and apparatus for imparting a positive phase slope (i.e., a negative group delay) to a narrowband signals is disclosed which adjusts the phases of the various frequency components of a signal in a manner opposite to that of a delay line. The invention also permits the amount of phase slope to be adjusted,electronically, without the need for electro-mechanical apparatus or the interchange of cables. Furthermore, embodiments of the present invention are advantageous inthat at the center of the operating band they maintain the phase of the delayed signal. These results are obtained in an illustrative embodiment of the present invention which divides the signal to be delayed into two signals which traverse differentsignal paths (715, 719) and are recombined in a signal combiner (729). The firstsignal path advantageously comprises a gain control block (717). The second signal path advantageously comprises a second gain control block (725) and a fixed linedelay (719) which is not found in the first signal path. The amount of phase slope imparted to the signal can be adjusted by varying the gain (or attenuation) of the respective gain control blocks (717, 725).
