Title: Blends of immiscible polymers having novel phase morphologies
Inventor: PUCCI MARK S
IPC: C08L23/08
Filed: 1992-03-11
Abstract: Unique phase morphologies of incompatible thermoplastic polymers, including a higher melting temperature polymer and a lower melting temperature polymer that has been sufficiently chemically compatibilized to form a stable interface in a two-phase system, are achieved by pre-melting the higher melting temperature polymer, adding the compatibilized lower melting temperature polymer in solid form thereto, and thereafter melting the lower temperature polymer with mixing. In particular, in poly(ethylene vinyl alcohol)/modified polyolefin systems, compositions containing between about 35 and about 55 wt. percent EVOH are formed in which the poly(ethylene vinyl alcohol) exists as a continuous phase and the modified polyolefin exists as discrete domains dispersed therein.  Such blended compositions have gas barrier properties comparable to homogeneous poly(ethylene vinyl alcohol).

Patent CA-2078303-A1 (CA)
Inventor: LOU PERRY W
IPC: G05F1/56
Filed: 1992-09-15
Abstract: A system for regulating an output voltage to a particular value includes a control transistor which produces an output voltage when energized by an energizing voltage. A voltage divider formed as by a pair of transistors with a particular ratio of transconductances divides the magnitude of this output voltage by a ratio related to the ratio of the transconductances. The transistors in the voltage divider may be respectively CMOS n- and p- transistors. The divided output voltage is introduced to a comparator (formed as from a pair of transistors) for comparison with a fixed reference voltage obtained as from a resistance ladder energized by the energizing voltage. The comparator introduces voltages to a comparator amplifier in accordance with such comparison. The comparator amplifier may include a transistor which produces changes in a current related to changes in the divided output voltage. The comparator amplifier may further include a current mirror which provides changes in a current related to changes in the current through the amplifier transistor. The current changes in the current mirror cause changes to be produced in a voltage (e.g. error voltage) from the current mirror. These error voltage changes are introduced to the control transistor to regulate the output voltage to the particular value.
