Abstract: A property such as moisture content in a sheet of material such as paper that both absorbs and strongly scatters infrared radiation is measured by passing the sheet through the central region of a substantially spherical cavity formed between a pair of concave mirror-surfaced, specularly reflecting bodies that are spaced apart to form a pass gap of sufficient width to allow substantially free movement of the sheet therethrough while substantially enclosing a first portion of the sheet on both sides. A spot of infrared radiation is projected onto one side of the sheet in the center of the cavity to illuminate a second portion of the sheet included within and substantially smaller than the enclosed first portion.  Thus infrared radiation scattered or transmitted by the second portion is reflected from the mirrorsurfaced bodies and directed back to the second portion substantially within the area of the sheet defined by the spot. The relative sizes of the first and second portions in relation to the width of the pass gap determine the relative quantities of radiation being retained in the cavity and escaping through the pass gap.  On the opposite side of the sheet relative quantities of both the projected radiation transmitted by the sheet and radiation reflected from the reflective bodies are detected so as to produce an output response indicative of the measured property.  The relative quantities of the retained and escaping radiation and the detected transmitted and reflected radiation are selected to make the output response substantially independent of changes in other properties affecting the scattering power of the sheet material, such as the bone-dry weight or composition of paper. ***************************

Abstract: A circuit and method is disclosed for detecting the presence of charges of appropriate magnitude and polarity on commutating capacitors of an inverter that converts a DC output current to a drive current of variable magnitude and frequency for driving an AC electric motor producing controllable rotation and torque. The presence of charges of appropriate magnitude and polarity is detected by measuring the voltages across the conduction controlled rectifying devices in the inverter. In addition, the existence of conduction controlled rectifying devices in the conducting state is determined by measuring the magnitude of the DC output current. An output signal is generated when the charges of appropriate magnitude and polarity are detected, which output signal is effective to allow the inverter to generate normal drive current. The absence of the output signal is effective to force the magnitude of the DC output current below a predetermined magnitude value and is effective to prevent the sequencing of gating signals to the inverter, whereby the drive current is such that the motor produces substantially zero rotation at substantially zero torque.

Abstract: A process for the production of a mixture of methanol and higher alcohols of "fuel grade" from CO and H2. To reduce the water content in the mixture coming from the synthesis reactor of the synthesis of the alcohols, the reaction product is cooled down and is fed to a secondary reactor wherein the conversion reaction CO+H2O-><-CO2+H2 is carried on in conditions near to equilibrium. The further product of reaction is cooled in a more thorough manner so as to obtain a liquid phase constituted by the "fuel grade" mixture of alcohols and a gaseous phase which after the discharge of the inert substances and after elimination of the CO2 is recycled to the synthesis reactor. In the secondary conversion reactor operation is carried out with a temperature comprised between 150 DEG  C. and 250 DEG  C., at a pressure equal to that of the synthesis reactor and in the presence of a copper catalyst.

Abstract: An inverter coupled to a source of DC input voltage is operated at the horizontal deflection frequency for developing a horizontal rate square-wave supply voltage. A power transformer having a first winding excited by the square-wave supply voltage develops a horizontal rate alternating polarity output voltage across second and third windings. A horizontal deflection generator is coupled to the second winding and is energized thereby to develop a trace voltage across a race capacitor. The deflection generator includes a trace switch coupled across the series arrangement of a horizontal deflection winding, the trace capacitor and the power transformer third winding. The trace switch is operated at a horizontal rate to generate horizontal deflection or scanning current in the deflection winding. A phase control circuit phases the alternating polarity output voltage relative to the phasing of the horizontal scanning current so as to apply a greater magnitude voltage across the horizontal deflection winding during the last half of the trace interval of each deflection cycle than during the first half of the trace interval. In this manner, linearity correction of the horizontal scanning current is obtained.

Abstract: The two ends of a length of fabric such as a papermaker's dryer belt 10 are joined together by a sewn loop pin seam which comprises two series of loops 20, 20a which are meshed with each other and interconnected by a pin 24 which passes through all the loops. The loops 20, 20a are formed by flat monofilaments 16, 16a interwoven with the ends of the fabric. The use of flat filaments 16, 16a which have a thickness substantially less than that of circular filaments of equal strength and less than that of the filaments forming the fabric, decreases the overall thickness of the pin seam and this makes it much less subject to wear when the belt is in use. <IMAGE>
