Abstract: CONTROL SYSTEM FOR CONTINUOUSLY       VARIABLE TRANSMISSION            Abstract The disclosed control system for a CVT controls the line pressure which is applied to the secondary pulley to maintain adequate belt tension, at a level significantly lower than previously was produced.          An improved throttle valve (40) is provided, and used in this throttle-sensitive regulation of line pressure.  An improved ratio valve (43) is pro-vided, which combines spring and fluid forces in a manner to produce the ratio-indicating fluid signal, with negligible loading on the movable sheave where the ratio change is sensed.  In the ratio-changing portion of the system (36), the combination of a timing valve (65) and accumulator valve (66) cooperate in demand type downshifts to provide adequate time for oil flow into the secondary pulley chamber as the primary pulley chamber is exhausted, to keep adequate belt tension during such a downshift.

Abstract: ABSTRACT OF THE INVENTION           A controlled amount of calcium pyrophosphate in dispersed  finely-divided  form is  included as  an inert additive in the phosphor coating of a fluorescent sunlamp to reduce the  emission of undesirable  short-wavelength ultraviolet radiation  (190 nm to 260 nm region).  From about 20% to 65% by weight of the calcium pyrophosphate additive is mixed with the phosphor and the amount is cor-related with the density of the phosphor-additive coating to  maintain  the  ratio  of  short-wavelength  ultraviolet radiation to erythemal radiation below a prescribed limit.          The additive particles are also larger than about 1 micron and are thus adapted to serve as a selective filter with respect to the undesirable short-wavelength radiations.

Abstract: Packoff and Seal Ring Assembly Abstract A packoff for sealing between an external cylindrical surface and a member therearound having a resilient ring, metal seal rings on the end surfaces of the resilient ring, the exterior of the resilient ring being concave to provide an annular recess, means for injecting and pressurizing plastic packing in said annular recess to cause sealing engagement of said metal seal rings and means to prevent leakage of pressure from the annular recess, and the inner and outer flanges on said metal seal rings providing a metal-to-metal seal.          Background The pressure, temperature and chemical conditions in many oil and gas wells are such that considerable difficulty has been experienced in prior packoff and seal ring structures for sealing around tubing, casing or a mandrel in oil and gas wells.   Resilient seals have been subject to permeation problems,  extrusion and breakdown when subjected to the elevated temperatures and high pressures encountered in such wells.  Further, many of such wells contain fluids and gases which may chemically attack the resilient material of such seals.    Use of metal-to-metal seals in such applications has re-quired selective sizing with respect to the outside diameter of the inner sealing surface.    Most current seals are resilient seal rings which require an anti-extrusion device but anti-extrusion devices, such as shown in U.S. Patent No. 4,219,204 are not applicable when there is a large range of gap widths to be bridged.  Such range results from allowed tolerances in the manufacture of

Abstract: MULTI-CAPACITOR FLUID LEVEL SENSOR ABSTRACT     A tubular shaped fluid level or fluid volume sensor or probe for mounting in a fluid storage vessel for sensing the level or volume of the fluid within the vessel which comprises: a first pair of like elec-trically conductive capacitor elements each formed to present two electrically connected capacitive plate areas, the capacitor elements being spaced from one another and shaped and arranged to generally define together the outer periphery of the tubular sensor; and a second pair of like electrically conductive capacitor elements each formed to present two electrically connect-ed capacitive plate areas, the second pair of capacitor elements being posi-tioned within and spaced from the first pair of capacitor elements and being spaced from one another and shaped and arranged to generally define together the inner periphery of the tubular sensor.  Electrical insulating material constitutes means located between the capacitor elements defining the outer periphery of the sensor and the capacitor elements defining the inner periphery of the sensor for mounting the pairs of capacitor elements in fixed spaced relationship from one another and for positioning the elements so that each capacitive plate area thereof defines with a capacitive plate area of the next adjacent capacitor element a dielectric space therebetween so that the mounted capacitor elements together form four like dielectric spaces.  Material of known constant dielectric value fills two of the dielectric spaces thereby forming with their respective space -i-defining capacitive plate areas two capacitors of known fixed and substantially like capacitive value.  The remaining two dielectric spaces are open to receive varying levels of fluid thereby forming with their respective capacitive plate areas, and the fluid within the spaces, two capacitors of variable capacitive value.  The sensor or probe is not limited in its application to fluid level or fluid volume measurements of liquids in vessels and may be used for volume measurement with respect to a wide variety of multi-component systems (including liquid/liquid, liquid/gas, liquid/solid, solid/gas, etc.) as long as the dielectric constants for the two or more components are different.                             -ii-

Abstract: Abstract In an optical information storage apparatus information is read from a magneto-optical storage medium by exploiting the self-coupling effect of a semiconductor laser. The invention is characterized in that a Faraday rotator is disposed in an optical path along which reflected light from the magneto-optical storage medium returns to the semi-conductor laser.  The polarization rotation angle of the Faraday rotator is selected so that the polarization plane of the semiconductor laser oscillates depending upon the perpendicular magnetization direction of the magneto-optical storage medium.  A linear polarizer is interposed between the laser and a photodetector whereby to detect a polarization component parallel or vertical to the junction plane of the laser by means of the photodetector.  The result is erasable and rerecordable data in the storage medium with a much improved signal to noise ratio over prior art methods.
