Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a vapor phase polymeriza-tion apparatus for olefins comprising a horizontal hollow cylindrical vessel having a lower curved surface which is constructed by a perforated plate, one or more agitator vanes on a driving shaft centrally located in said vessel, an olefin feed chamber mounted so as to cover from below said perforated plate and adapted to feed a olefin gas through said perforated plate, a polymerization catalyst inlet port, a polymer outlet port and an unreacted olefin gas discharge port, which ports are all provided in other portions than the curved perforated portion of said vessel.  With this apparatus hot spots are not usually formed during polymerization, so that there is no production of block-like polymers and less power is needed for agitation.  Also, with this apparatus, it is possible to produce polymers having a suitable particle size distribution at low cost and which are stable.

Abstract: ADJUSTABLE REEL Abstract of the Disclosure Optical fiber wound onto a take-up reel after production is invariably tensioned such that results of characterization tests performed on the wound fiber are markedly different from such results obtained when the fiber is untensioned. Doubly winding the fiber to minimize tension is a laborious procedure.  The invention covers a reel which has an adjustable hub circumference.  Adjustment can be made with the fiber wound onto the hub so allowing rapid characterization of the fiber prior to restoring the fiber and the hub to their normal storage positions for fiber shipment.                               - i -

Abstract: A MULTIPLE FUNCTION OPERATIONAL AMPLIFIER CIRCUIT         ABSTRACT    An operational amplifier capable of selectively performing a variety of circuit functions is provided.  A single operational amplifier utilizes switched capacitors for sampling and holding an input signal, for establishing a low frequency pole, for applying the sample to an output capacitance to charge the capacitance and for comparing the input signal with a reference.  The multi-function circuit provides a large savings in circuit area and permits versatility of circuit applications.  One embodiment of the invention is to utilize a companding DAC having a capacitor array which may be used as the output capacitance of the operational amplifier circuit.  The DAC provided utilizes an R ladder DAC coupled directly to a C DAC and has a switching structure that is simpler than comparable prior art circuits,  The DAC is asynchronous and has programmable A-and Mu-255 law PCM conversion capability.  Coupled directly to the C DAC is an operational amplifier receive filter circuit which utilizes the C DAC as an input capacitor thereby eliminating the need for a buffer amplifier and allowing the DAC to be used for both analog to digital and digital to analog conversion.

Abstract: METHOD FOR MONITORING AND CONTRO LING THE           DISTRIBUTION OF DROPLETS ON A SURFACE                Abstract of the Disclosure Method for monitoring the weight of glue sprayed on a veneer surface, where the light reflectance from droplet-covered regions on the surface differs from that of uncovered surface regions.  According to the method, a beam of light is directed onto the sprayed surface of a relatively moving veneer, and the light reflectance from a zone within the illuminated surface area is detected to produce a signal which varies according to instantaneously detected reflected light level.  A signal-handling circuit transforms the signal to a binary data stream composed of one and other data states representing reflected light levels from droplet-covered and uncovered regions on the surface, respectively.  The data stream is processed to compute the weight of glue sprayed on the surface.
