Title: Optical path length difference interferometer method - uses intensity levels sensed at three different optical path length differences, and trigonometric function
Inventor: BALASUBRAMANIAN N
IPC: G01B9/02
Filed: 1980-06-30
Abstract: The method for determining interferometric optical path length difference includes varying the interferometric optical path length difference between a first and a second surface in three steps at one-quarter wavelength intervals. The intensity of the interferogram radiation at at least one position of the interferogram is sensed at each of the steps. The intensity sensed a each position is stored at each step. For each of the positions the intensity of the first and third steps is added to produce a d.c. spatial frequency amplitude. The intensity of the third step is subtracted from that of the first to obtain the cosinusoidal spatial frequency amplitude, and the intensity of the second step is subtracted frequency amplitude. The sinusoidal and cosinusoidal amplitudes are combined to produce a trigonometric function of the phase angle of the radiation reflected from each position of the first and second surfaces. From the trigonometric function of the phase angle an output representative of the optical path length difference at each position is generated.

Title: Tapered-ring vortex chamber for extreme acceleration of the vortex medium
Inventor: REIBER KURT
IPC: F15D1/00
Filed: 1982-01-26
Abstract: The side walls of the tapered-ring vortex chamber extend inwards in a funnel shape, so that they form a tapered ring with the circular outer wall. The vortex material injected through the outer wall at an angle to form a vortex can flow out in the vicinity of the vortex core, because the funnel walls are open at that point. Conventionally, the vortex chamber narrows towards the vortex centre with the square of the approach. Due to the tapered-ring shape, the chamber space tapers inwards also in the width of flow, so that the inward narrowing of the space goes with the cube. As a result, the vortex medium in the tapered-ring vortex chamber is subjected to an extremely high acceleration. Industrial utilisation in:     1. centrifugal separation equipment, 2. pre-acceleration of the propellant medium for liquid turbines and pre- and re-acceleration for gas turbines,   3. pulsed combustion chambers with vortex acceleration,   4. pulsed combustion turbines,   5. ultrahigh-speed small turbines and 6. extreme high-speed water turbines with a blade drive for cutting by vortex water. The drawing shows the tapered-ring vortex chamber with an air cushion antechamber for liquids, to reduce the inflow resistance. Tapered-ring vortex chamber with air cushion antechamber for high-speed liquid turbines:   1. Vortex liquid in the tapered-ring vortex chamber and in the air cushion antechamber with the centrifugal force rising outwards.   2. Injection orifice into the air cushion antechamber.   3. Air cushion antechamber.   4. Air cushion buffer space.   5. Compressed-air feed, if necessary.   6. Overflow ring orifice.   7. Vortex outflow orifice.   8. Turbine shaft.   9. Open outflow chamber.   <IMAGE>

Title: Apparatus for the abrasive blasting of precision workpieces
Inventor: JACOB FRIEDRICH
IPC: B24C9/00
Filed: 1982-04-21
Abstract: On workpieces, in particular on cast dental parts, moulding-material residues or the like have to be removed by abrasive blasting. To this end, the workpieces are acted upon in a blasting chamber (11) of the apparatus by a mixture of compressed air and blasting medium. The air escaping from the blasting chamber (11) is mixed with solid particles from the moulding-material residues during the blasting operation. In order to prevent these solid particles from escaping from the apparatus together with the air, the mixture escaping from the blasting chamber (11) is mixed with an air/liquid mixture in a conveying section in the form of a suction tube (33), as a result of which wetting of the solid particles with the liquid, in particular water, sprayed into the suction tube (33) takes place. The moist solid particles separate from the surrounding air while forming sludge. The air thus purified escapes through an additional filter (48) out of the housing (10) of the apparatus. <IMAGE>
