Title: Determination of phases and phase differences of light reflecting from specular or diffusely reflecting, or transparent surface of object
Inventor: ETTENMEYER ANDREAS DR ING
IPC: G01J9/02
Filed: 1995-04-07
Abstract: The method for determining the phases of light or infra-red radiation reflected from an object (10) with a diffusely reflecting surface, in a displaced or distorted condition, or from a transparent or mirrored object in similar conditions, uses a movable and rotatable glass plate (23). Rays of known frequency (11) are directed at the object and reflected from it (12) through the lens (13) towards a sensor (15) made up of multiple pixels (16). A reference ray (14) of equal frequency, transmitted through the turning glass plate, changes in definition. In this way the phase position between object rays and reference rays is modified to produce, after processing, a single phase difference value (17).

Title: Separating particles from fluid streams, e.g., dewatering sludge
Inventor: SCHATZ JUERGEN
IPC: B04C3/00
Filed: 1995-10-20
Abstract: The separation of fluids and/or solids from free-flowing material streams, such as a separation of fluids from solids in a free-flowing stream or light and heavy solids, proceeds due to centrifugal force. A material stream containing solids is whirled under pressure, e.g. centrifugal pressure, in a main vortex in the form of a rotating mass. Near the highest outer peripheral speed of the main vortex, controlled by a drive, a number of band like volumetric flows are pared off, and fed with peripheral velocities in accelerators into cylindrical cyclone chambers where their rotation direction and momentum are reversed from that of the main vortex in the arising secondary vortices. These secondary vortices develop increasing peripheral velocities towards the inside, and also side vortices, e.g. of fluid with a low pressure core boundary layer and solid particle vortices in the low pressure core. The side vortices  and solid particle vortices are accelerated in the direction of the outlet openings and coaxially but separately removed.   Also claimed is the device for performing the above process having an inlet pipe (3) on a main axis of rotation (1) above a drive chamber (22) with a central drive (4).  Concentrically around the axis of rotation, on secondary axes of rotation (2) there are cylindrical accelerators (7) with inlet openings (8) and guide surfaces (14), delimited above and below by cover plates (11) and jetting cones (10) with outlet openings (9).  There is a pressure potential acting from the inlet pipe (3) to the outlet openings (9) of the accelerators.

Abstract: The regulator regulates an medium flow fed from a medium supply to a hydrostatic or aerostatic pocket of a bearing, threaded spindle or a guide. The regulator has pressure chambers separated from a control element moved against the force of a spring element. A first pressure chamber actuated with a first pressure level (p1) is connected directly to the medium supply. A second pressure chamber actuated by a second, lower pressure level (p2) is connected to the supply via a first resistor. A third pressure chamber actuated by a third pressure level (p3) corresponding to that in the hydrostatic or aerostatic pocket is connected to the pocket. The control element forms a variable second flow resistance between the second and third pressure chambers, which affects the flow fed to the pocket. The size of this second resistance is increased by the force of a first pressure chamber but is reduced by the effect of the spring force as well as the force of the second and third pressure chambers. A bypass (29) is provided with a third, preferably fixed, flow resistor (33). The third resistor is connected to the hydrostatic or aerostatic pocket and also, via the first resistor (21), to the medium supply.
