Abstract: 27.                        SOLID STATE DEVICES BY DIFFERENTIAL PLASMA ETCHING OF RESISTS Abstract of the Disclosure This invention relates to production of solid state devices by a process which includes at least one pattern delineation step involving dry etching of a negative resist deposited as a film on a substrate and obtained by mixing a host polymer with one or more monomers capable of being locked into place by electromagnetic radiation.  The film is selectively irradiated, fixed, for example by heating or vacuum or both, to remove unlocked monomer or monomers from the film, and etched by means of an oxygen-containing plasma. The rate of removal is higher in the unirradiated region than in the irradiated region, yielding a negative resist pattern.  A sensitizer may be added to allow use of various radiation wavelengths. Desirable properties of monomer and host polymer materials are discussed, and exemplary specific compositions given of aromatic monomers, silicon-containing monomers, and chlorinated polymers.

Abstract: ABSTRACT OF THE DISCLOSURE A canvas tarpaulin having dimensions sufficient to cover the top of an open truck box has one edge affixed to one longitundinal edge of the truck box top.  The opposite edge of the tarpaulin is affixed to a tube which extends for the lenth of the box.  The rear of the tube contains an extension attached to a universal joint.  A crank handle is also attached to the joint so that the tube can be rolled transversely across the top to roll up the tarpulin thereon. A downward cantilevered lip is attached to the opposite longitudinal edge of the box top.  When the tarp is unrolled, the tube rolls over a free edge of the lip and can be wound in the opposite direction rolling up a small portion of the tarpaulin under the free edge.  The crank handle is then moved against the rear of the truck body thus locking the universal joint thereby holding the tarp tightly upon the box top.  The crank handle is then secured against the rear of the box.

Abstract: ABSTRACT OF THE DISCLOSURE         A filter apparatus is disclosed for filtering out any reoccurring noise present in a defect signal received from a flow detection device such as an eddy current test probe.  Filter circuit means receives the defect signal generated by the flaw detector device and produces an output signal duplicative of any reoccurring noise present therein.  A differential amplifier substracts the output signal of the filter circuit means from the defect signal generated by the flaw detection device and amplifies the difference.  A filtered defect signal void of any reoccurring noise is thereby produced.

Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed is a novel sulfated biopolymer, a method for synthesizing the sulfated biopolymer and an oil recovery method employing an aqueous fluid containing the material.           The sulfated biopolymer is made by reacting polysaccharides with sulfuric acid in the presence of an aliphatic alcohol at a temperature of from 35 to 75°F, in order to avoid degradation of the polymer by the sulfuric acid.  The polymer produces a viscous solution which is less prone to increasing viscosities as shear rate is decreased, which makes it especially suitable for use as a viscosifying polymer in a polymer flooding enhanced oil recovery process.

Abstract: POWER DRIVE LINE HAVING A WIDE     RANGE OF SPEED RATIOS     A power drive line in which a continuously variable, nutating traction drive transmission unit is combined with a single planetary gear set to provide two forward modes and a reverse mode of drive line operation.          A pair of transmission unit input shafts are alternately coupled to a power input to the overall drive line.  In one forward mode, the planet gear is driven by the sun gear to rotate the ring gear in a relatively wide low speed range of speed ratios.  In another forward mode, the transmission body carrying the planet gear is connected to be driven directly by the drive line power input to effect a relatively high range of output speeds for a given input speed.  In the reverse mode, the body carrying the planet gear is held against planetary movement so that the planet gear operates as a reversing idler between the sun gear input and the ring gear output.

Abstract: TITLE OF THE INVENTION:     METHOD AND CIRCUIT ARRANGEMENT FOR CONTROLLING THE R.P.M. OF A THREE-PHASE MOTOR            ABSTRACT OF THE DISCLOSURE:          The present method and circuit arrangement control the r.p.m. of a three-phase motor connected in a star or Y-circuit by sensing current variations in the star point of the motor windings.  These current variations are con-verted into voltage variations which represent the current input of the motor windings.  These voltage variations are used to control the duration of the application of the operating voltage to the motor windings for varying the motor r.p.m.  The circuit for this purpose includes a controlled diode circuit arrangement connecting the motor windings to the star point and a control or drive circuit for controlling the diode circuit arrangement.  The drive circuit makes the diode circuit arrangement conductive for predetermined time durations which depend on the voltage variations.  These time durations are also manually adjustable in an open loop control, whereby a closed loop control is provided in com-bination with an open loop control.
