Abstract: Abstract Process for the manufacture of coarse aluminum hydroxide, con-taining a maximum of 15 weight percent of the particles in a par-ticle size under 45 micrometres, with a productivity that may be higher than 60 grams of precipitated Al203.   The process consists of a decomposition in two stages (an agglo-meration phase and a growth phase); each stage proceeding within defined temperature ranges with seed material of different con-stitution.  The first (fine) seed amount is added at the start of the decomposition in such an amount, that the ratio of the super-saturation of the aluminate liquor to the surface area of the seed position exhibits a value of 7 to 25 grams per square metre.  The process exhibits the advantage of the high productivity of the so-called European process and the advantage of the so-called American process by obtaining a coarse product hydroxide.

Abstract: ABSTRACT OF DISCLOSURE     To select a blend of strains not susceptible to the current bacteriophage in the cheesemaking plant the cheesemaker inoculates each of the test tubes in the kit with filtered whey obtained from current production.          Each tube contains a genetically distinct starter culture strain or a culture blend in a sterile milk medium and contains a dye which will change color in the desired pH range.  After incubation for ten hours the cultures resistant to the prevailing phage will exhibit the desired color change and will have developed a firm curd.  A starter culture now known to be resistant to the prevailing phage can now be selected.  Tests show success closely approaching 100% as opposed to 96% (or less) with the traditional rotation method of selecting culture blends.

Abstract: RCA 72,790 Abstract of the Disclosure A controlled oscillator comprises an amplifier including an active device, a filter network arranged in a feedback loop of the amplifier for providing regenerative feedback to sustain oscillation of the amplifier, and a source of control signals.  Output oscillatory signals from the amplifier and output control signals from the control source are summed by a combining network to produce a resultant controlled signal, which is coupled to the filter network.  Parasitic capacitances associated with output terminals of the amplifier and control source impart an unwanted phase shift to the controlled signal. A compensation signal derived from the oscillator is supplied to the combining network with a magnitude and phase to offset the unwanted phase shift, to thereby produce a phase compensated resultant controlled signal.

Gradient index fibers are arranged in single row or double row (bundled) configuration with fibers increasingly departing from the perpendicular condition at the center of the array relative to object and image planes in a characteristic fan-like manner. Fiber lengths are adjusted to compensate for changes in total conjugate which occur because of the progressive tilting of the axes of the individual fiber lenses. This is achieved, in one embodiment, by grinding the faces of a lens array into a convex configuration.
