Abstract: A circuit arrangement (12, 13) for the electronic level control of a sound signal includes an amplifier circuit (14), the gain of which can be controlled in dependence on a variable direct control voltage, and a voltage-adjusting stage (15) for generating the variable direct control voltage. The amplifier circuit is formed by a CMOS inverter (14), of which the supply voltage connection (21), is supplied with the variable direct control voltage, generated by the voltage-adjusting stage (15), as supply voltage for the CMOS inverter (14). The CMOS inverter (14) is operated, in dependence on the direct control voltage, below the knee-point voltage in its starting region in which the gain of the CMOS inverter (14) decreases, and additionally the dynamic output impedance of the CMOS inverter (14) increases, with decreasing direct control voltage.

Abstract: ABSTRACT           This invention relates to a reinforce fabric composition and to a method of making the same.  The fabric composition includes a fabric base, a heat conductive metallic foil secured to the base, and a non-woven batt of fibers over the metallic foil, the batt and the foil being mechanically locked to the base solely by fibers of the batt which have been pushed through the foil and through the base and are locked against the bottom of the base.          The preferred method of the present invention involves applying the metallic foil over a web of the fabric base, applying a non-woven batt of fibers over the foil and needle punching the resulting composite with barbed needles while incrementally advancing the composite to force fibers from the batt through the foil and through the fabric base to thereby densify the composite and securely interlock the fabric base, the foil and the batt together.

Abstract: ABSTRACT OF THE DISCLOSURE       A ventilator for use with sheet metal roofing either of the batten type using elongated pan sections or flat sheets.         In a preferred form of the invention using sheet metal pan sections between battens, the pan sections are lap-joined at the ridge of the roof and a ventilator opening is cut in the over-lapped end portions of the pan sections and in the underlying roof on either side of the ridge of the roof.  The base member of the ventilator is formed from a single sheet of metal and has a cen-tral opening coinciding with the opening in the pan section.  The edge portions of the central opening in the base member of the ventilator are upturned to form side walls defining the ventilator opening and a screen is fitted into the opening.  Downwards of the ventilator opening, on each side of the ridge of the roof, the lower edge portions of the base member are folded back on them-selves in curved form to form wind breakers extending between bat-tens of the pan sections.  A cover member for the ventilator is secured to the top surface of the battens on either side of the ventilator and the lowermost edges of the cover are bent downwards and backward on themselves to form troughs between battens and combine with the wind breakers to form offset air passages be-tween the interior of the ventilator and the exterior of the roof, with the wind breakers having a suction effect to draw air out-wards from the interior of the roof.

Abstract: A PROCESS FOR PRODUCING LOW POROSITY CEMENT   Abstract of the Disclosure A method is disclosed for making low-porosity, free-flowing cement pastes with extended set times, improved workability and reduced expansion due to alkali aggregate reactions, by combining hydraulic cements, especially portland-type cements, ground without gypsum with from 0.1% to about 1.0% of an alkali or alkaline earth lignosulfonate or sulfonated lignin, combining 20% to 40% of water with 0.1% to 2.0% of an alkali bicarbonate, and thereafter mixing together the combined cement and lignin with the combined water and alkali bicarbonate.  As an alternate embodiment of this process, the alkali or alkaline earth lignosulfonate or sulfonated lignin may be added to the water-bicarbonate rather than blended directly with the cement.  These low-porosity pastes when mixed with aggregates produce mortars and concretes that have extended set times and are very workable during processing.
