Patent AT-A279686-A (AT)
IPC: C08G63/78
Filed: 1986-10-21
Abstract: In a continuous process for the preparation of aromatic polyesters by polycondensation of 9,9-bis(4-hydroxyphenyl)fluorene with isophthaloyl chloride and/or terephthaloyl chloride as dicarboxylic halide by the two-phase interface polycondensation process, a fine preemulsion is first prepared continuously from the aqueous phase, comprising a solution of the diphenols, alkali metal hydroxide for formation of the diphenoxides and optionally a phase-transfer catalyst, in water or a mixture of water and an organic solubiliser with an organic solvent, the preemulsion is fed together with the acid chloride solution-forming organic liquid phase, to a disperser in amounts such that the compounds participating in the polycondensation reaction are mixed in a disperser in a constant ratio to one another with formation of a reaction emulsion, which then passes successively through one or more dispersers and/or static mixers while the polycondensation proceeds and is completed. The phases are then separated, and the polyesters formed are precipitated from the organic phase by feeding in acetone. <IMAGE>

Abstract: The tire comprises a tread with central grooves between exterior grooves. Both types of grooves extend in a zig-zag shape in the circumferential direction and define ribs between them. Each one of the central grooves is bounded by sidewalls which define two opposite sidewall sections between angled regions of the central grooves. The two sidewall sections alternate from one angled region to the other in the circumferential direction of the tread. A first sidewall section of the two opposite sidewall sections extends at least approximately normally to the tread and a second sidewall section of the two sidewall sections comprises two sidewall portions extending substantially normally to the tread and an interconnecting flank portion therebetween which extends at an inclination in the range of 20 DEG  to 60 DEG  with respect to a line perpendicular to the tread. The angled regions are located between consecutive groove sections and each one of the angled regions comprises a protruding or salient angled region and a receding or reentrant angled region each of which, in turn, is constituted by a first corner section extending substantially normally to the tread and a second corner section extending at an inclination towards the base of the groove and forming two substantially triangularly shaped portion which converge to a common point in the direction towards the base of the groove.

Abstract: RECIRCULATING PROCESSING OVEN HEATER                 ABSTRACT OF THE DI CLOSURE          A recirculating processing oven heater including a di-rect fired burner for heating processing gas and a catalytic con-verter downstream from the burner for removing unburned combus-tible gas and providing additional heating prior to delivery of the processing gas to an associated processing oven.  A housing of the heater defines first and second parallel paths along which the gas flows between an inlet and an outlet thereof and the burner and catalytic converter are located along the first path to heat gas flowing therealong while mixing of the gas downstream therefrom at a junction of the two paths provides heating of the gas that flows along the second path.  The rela-tive mass flow rates of gas flowing along the first and second paths is adjustable by a control valve mechansim including first and second adjustable valves at the inlet of the heater housing.  Each valve preferably includes a plurality of dampers and an adjustable actuator that positions the dampers.  The ac-tuator for the first valve is power operated in response to the temperature of processing gas within the associated oven fed by the heater while the actuator of the second valve is manu-ally adjustable.  Inner and outer housing portions of the heater housing have hollow elongated shapes with round cross sections and are arranged in a coaxial relationship such that the inner housing portion defines the first gas flow path and the space between the inner and outer housing portions defines the second gas flow path.  An upstream end of the inner housing portion receives the burner while a downstream end thereof mounts a con-ical mixing member for causing mixing of the gas from the two paths within a mixing chamber defined by the outer housing por-tion adjacent the downstream end of the inner housing portion.          An adjustable fresh air inlet in the outer housing portion, an-nular baffles along the first and second gas flow paths, and a blower within the outer housing portion downstream from the mix-ing chamber cooperate with the other components of the heater during its operation to provide efficient heating of processing gas for delivery to the oven.

Abstract: ABSTRACT OF THE DISCLOSURE A voltage controlled oscillator includes a tank circuit including a quartz vibrator and a phase shifter connec-ted to the tank circuit for forming a vector signal e1 from the tank circuit and a vector signal e2 delayed a predetermined angle from the signal e1.  A differential circuit is used to subtract e1 from e2 thus forming a difference signal e3.  The delayed signal e2 is inverted by a phase inverting circuit to obtain two signals e2 and -e2 which are applied to an addition circuit where their relative amplitude ratio is controlled.          The addition circuit adds signal e3 to the signals e2 and -e2 whose relative amplitude ratio has been controlled for producing a sum signal which is fed back to the tank circuit.  This pro-vides a multi-function circuit element which can be readily incorporated into an integrated circuit unit thus decreasing the number of pins thereof for external connection.  The circuit of this invention is suitable for providing hue adjustment and for providing demodulation signals in the colour signal proces-sing circuit of a colour television receiving set.
