Title: Integrated-optic endless polarization transformer
Inventor: HEISMANN FRED L
IPC: G02B6/12
Filed: 1990-01-23
Granted: 1994-05-03
Abstract: INTEGRATED-OPTIC ENDLESS POLARIZATION TRANSFORMER Abstract Cascadability and simplicity of design and operation are primary attributes of a novel electrooptic polarization transformer for reset-free endless polarization control that allows general polarization transformations from any arbitrarily varying input and into any arbitrarily varying output polarization by producing adjustable elliptical birefringence of constant total phase retardation in a single-mode waveguide. Here, a particular transformation is obtained by adjusting the azimuth of linear birefringence and the ratio of linear to circular birefringence. In this integrated-optic realization, the endless polarization transformer includes at least one cascadable transformer section comprising a first TE   TM mode converterfollowed by a first TE/TM phase shifter followed by a a second TE   TM mode converter and a second TE/TM phase shifter. The sections are formed over a birefringent waveguide capable of supporting propagation of TE and TM optical signal modes.

Title: Extruding a marbleized synthetic resin strand
Inventor: LAARMANN WILLI
IPC: B29C48/12
Filed: 1991-03-06
Granted: 2000-02-01
Abstract: A marbleized thermoplastic resin strand is made from a matrix resin and an inlay resin in an apparatus having a die forming a passage extending along an axis and having an upstream inlet end and a downstream outlet end and an extruder for injecting the matrix resin in hot liquefied condition into the passage at the upstream end thereof such that the resin emerges from the downstream end. An inlay nozzle opens into the passage between its ends and extends through the die along a nozzle axis not parallel to the passage axis. The inlay resin is fed in hot liquefied condition through the nozzle into the passage such that the inlay resin mixes with the matrix resin. The inlay nozzle is rotated substantially continuously about its nozzle axis so long as the extruder is operating, Thus the patterning of the inlay resin in the matrix resin is a function of the rotation speed of the inlay nozzle.

Filed: 1991-11-29
Granted: 1996-07-23
Abstract: A liquid dispensing system utilizes a microprocessor based electronic control and a positive displacement gear pump to accurately meter predetermined batches of liquid from a supply tank.  The gear pump is driven by a reversible motor through a gear reducer, and is operative to pump a predetermined fixed volume of liquid for each revolution or fraction of revolution of the pump drive shaft.  A passive magnetic sensor is positioned adjacent the toothed periphery of a target wheel, which is mounted on the motor shaft, and generates a signal representative of the amount of rotation of the pump drive shaft.  The electronic control is responsive to this signal for calculating the total volume of liquid displaced by the pump.  The electronic control includes a keyboard which enables a user to preprogram the precise amount of liquid to be dispensed.  The system includes a discharge hose for dispensing the liquid into a user's container, which hose is automatically primed by the system prior to the dispensing operation.  The system can also be provided with a provision to "drain back" the liquid into the supply tank after the dispensing operation, and/or to recirculate liquid through the supply tank when it is desired to mix the contents thereof.

Title: Downhole adjustable stabilizer
Inventor: ASKEW WARREN
IPC: E21B7/06
Filed: 1992-01-31
Granted: 1999-02-16
Abstract: In accordance with illustrative embodiments of this invention, a downhole adjustable stabilizer includes a sleeve having outwardly extending blades and mounted for limited rotation on a mandrel, vertically aligned sets of radially movable buttons mounted in bores in the blades, and longitudinal flats on the outer periphery of the mandrel that when radially aligned with the respective sets of buttons allows them to shift inward to positions where the stabilizer becomes undergage and can be tilted in the borehole.  Some spring loaded buttons drag against the borehole wall to provide frictional restraint against rotation of the housing.  The blades can each have an inclined side surface that causes the sleeve to be rotated to its position relative to the mandrel where the sets of buttons are retracted as the stabilizer slides downward in the borehole. In another embodiment a hydraulic delay is provided which restrains relative rotation in the direction which causes the buttons to extend to their full gauge diameter.
