Abstract: PREPARATION OF PHOTOCHROMIC GRADIENT LENSES            OF COSMETICALLY IMPROVED COLOR Abstract of the Disclosure Glass lenses, or lens blanks, containing all the ingredients necessary to produce phototropic, or photochromic, behavior, are treated in a conventional production furnace to produce a locally variable heat treatment, wherein at least one portion thereof is raised to a temperature exceeding the glass strain point but not the softening point, and other portions are heated to variable temperature decreasing from the strain point.  The treatment causes development of phototropic, or photochromic, behavior only in those portions of the lenses, or lens blanks, exposed to the temperature above the strain point.  The lenses resulting are characterized by trichromatic coeffioients, x=0.306 and y=0.307, in the unactivated state and x-0.324 and y=00321, in an activated state and including a small but effective quantity of cobalt oxide.

Abstract: WATER COLLECTING DEVICE FOR AN ANIMALS WATERING VALVE     ABSTRACT OF THE DISCLOSURE     A water collecting arrangement for providing water particularly for small animals such as baby chicks, in which a water collecting bowl with an actuating lever pivotably mounted therein, actuates a watering valve.  The watering valve is connected, on one end, to a water pipe, and a free end of the valve is connected to a valve stem for actuating the valve.          The stem moves with the actuating lever.  An elastic holding clamp  which may be attached to the water pipe without the use of tools, holds in place a bottom portion containing the collecting bowl, by means of a bayonet-catch quick-connecting arrangement.          The bottom portion is insertable into the holding clamp and can be connected detachably, without tools, by turning through an angle of substantially 90°.  The holding clamp has a U-shaped cross-section and a center bar which has a passage in the center for the watering valve.  The holding clamp, furthermore, has a smaller clearance width between the free ends of its outer legs.  A T-shaped groove or recess is provided in the holding clamp, which is open to the outside and serves as a fastening element for the bottom portion.  The T-groove or recess on the center bar is in the zone of the passage and extends lengthwise on the center bar.

Abstract: ABSTRACT OF THE DISCLOSURE          This invention discloses a novel chair control for use with a tiltable stenographer's chair.  It discloses a compact and improved biasing means to control the movement of the movable frame member, this biasing means being a U-shaped bolt with two helical springs thereon, inserted from the front of the chair control about which the movable frame member pivots.  This new biasing means eliminates unsightly handwheels and associated mechanisms hanging down from the control and provides an extremely compact device.  Also disclosed is a wrench permanently carried by the biasing means for adjustment thereof, the wrench folding out of the way after use.  A second biasing means is disclosed which depends from the plate affixed to the seat and eliminates unsightly mechanisms from the front of the control.  The chair controls of all the embodiments include a movable frame member which includes a downwardly depending portion at the rear of the first bracket which is affixed to the fixed frame portion which strengthens the control thereby reducing damage to the control caused by continual use.

Abstract: ABSTRACT OF THE DISCLOSURE          A method for producing synthetic liquid absorbent granules to serve the same purposes as granules made from naturally occurring sorptive minerals such as absorbent clays.  Water is mixed with powdered gypsum plaster in mixing apparatus and a paste or slurry condition results, with the volume of water relative to the plaster being varied to vary the bulk density and the absorption capacity characteristics of the ultimate granular product from each mix.  The mix is taken from the apparatus and is allowed to set and harden in a form to be readily handled for crushing and sizing into desired screen mesh size granules, or the mix can be directly formed into pellets or granules so as to be allowed to set and harden and be cor-respondingly sized as the commercial product.  Additives can be included in the mixing to vary the density and the absorption characteristics of the final absorbent granules.  The fines recovered from screening and sizing the material can usually be introduced into the mix with the plaster and the water, whereby the otherewise unuseable fines have a useful function in the method and in the product manufactured thereby.

Abstract: ABSTRACT           A shear liquid fan drive coupling for the radiator cooling system of an internal combustion engine of the type wherein a temperature responsive valve controls the degree of rotary coupling between the engine and a radiator cooling fan by controlling the active quantity of shear liquid in a liquid coupling between the engine and the fan.  The speci-fic improvement relates to a bi-metal strip for the temperature controlled fluid coupling, the strip being so configured that it cannot be mounted on the housing of the coupling except in a predetermined orientation therewith.   In this manner, overheating of the engine due to faulty mounting of the bi-metal strip is precluded.

Abstract: ABSTRACT OF THE DISCLOSURE            There is provided a milk substitute for use in leavenable food compositions, i.e. foods containing a cereal, shortening and, normally, milk.  A portion of the milk normally used in those conventional compositions is replaced by a milk substitute which is a combination of de-proteinated and de-ashed whey and a food-grade neutralized caseinate.  Substantial amounts of the milk and,in many of the compositions all of the milk, may be replaced by the milk substitute and the leavened volume of the resulting food will be essentially equal to the leavened volume of the conventional food made with milk.  In baked foods, pore size, texture and crumb characteristics are maintained with the present milk substitute.
