Abstract: ABSTRACT           The roll assembly of a calender has at least one roll with a deformable shell which surrounds a rigid carrier and whose end portions surround discrete antification bearings.  The intermediate portion of the shell surrounds one or more rows of hydrostatic supporting elements which can be acted upon by adjustable fluid-operated motors to change the shape of the intermediate portion in a plane including the axes of the one roll and the neighboring roll as well as at right angles to such plane.  Stresses which are applied to the bearings for the end portions of the shell are monitored by several sensors which transmit signals to a control system to regulate the deformation of the shell in such a way that the stresses upon the bearings are minimized or reduced to zero. This enables the intermediate portion of the shell to undergo deformation which is best suited for optimum treatment of the material passing through the nip of the one roll and the neighboring roll.

Abstract: Abstract DIGITAL LIMITER A soft digital limiter (2) for limiting an analog input signal (1) from a maximum expected range (61) to a useful range (60).  The number (m) of desired levels of resolution in the limiter (2) is preselected to be any power of two.  An analog-to-digital converter (9) converts  the  input  analog  signal  (1)  to  a  digital representation (20).  The converter (9) has its input voltage rating matched to the maximum expected range (61)   and  its  output  resolution  matched  to  the preselected   degree   (m)   of   resolution.    In   the preferred  two's  complement  numbering  system,   the condition for the input signal (1) falling within the useful  range  (60)  is  that  the most  significant  p+1 bits  of  the  digital  representation  (20)  are  all identical, where p is the number of bits required by the  converter  (9)  to  delineate  that  portion of  the maximum  expected  range  (61)  outside  of  the  useful range (60).  A network of comparators (e.g., 38, 39) implements this condition.

Abstract: ABSTRACT     A heat recovery apparatus for boilers, or the like, comprising a heat recovery housing generally having a pair of side walls, a pair of end walls connected to the side walls, a top and a bottom.  A com-bustion gas inlet is disposed within the bottom, and a combustion gas outlet is positioned within the top.  A plurality of interconnected water conduit tubes is provided with a cold water inlet in communica-tion with one of the end walls and a hot water exit also in communica-tion with one of the end walls.  The water conduit tubes pass circuitous-ly through the heat recovery housing.  A tube roof is interconnected between the pair of end walls above the water conduit tubes and above the cold water inlet and above the hot water exit.  A plurality of by-pass dampers pivotally connect between the pair of end walls such that when the by-pass dampers are in a closed position the closed by-pass dampers define a generally flat by-pass structure angularly dis-posed with respect to the horizontal plane and extended between the pair of end walls and from one of the pair of side walls to the tube roof in order to divert or change the direction of flow of combustion gases from the combustion gas inlet towards the water conduit tubes. A condensate drain is positioned in the bottom of the recovery housing and underneath the water conduit tubes.  A plurality of exit dampers is pivotally connected between the pair of end walls such that when the exit dampers are in a closed position, the closed exit dampers de-fine a generally horizontal flat exit structure extending between the pair of end walls, and from the opposed other wall of the pair of end walls from which the by-pass dampers extend from, to the tube roof in order to pivotally open to allow the flow of combustion gases from the water conduit tubes through the combustion gas outlet.  The pro-cess for recovering heat from hot combustion gases flowing through the combustion gas inlet comprises closing pivotally the by-pass dampers which essentially simultaneously divert or change the direction of flow of the hot combustion gases towards the water conduit tubes in order to effect a heat transfer between the hot gases and the water passing circuitously through the conduit tubes and extract con-densate from the hot gases which accumulates in the bottom of the heat recovery housing.  The process additionally includes opening pivotally the exit dampers to allow the passage of gases from the water conduit tubes to the combustion gas outlet, and draining accu-mulated condensate from the bottom of the heat recovery housing through the condensate drain.

Abstract: "VERTICAL TUBE REACTOR WITH SERIAL-DOWNWARD FLOW THROUGH     A PLURALITY OF SETS OF PARTICULATE CONTAINING TUBES"   ABSTRACT           A single pass, shell and tube reactor which is designed for downflow  of reactant fluid in tubes containing contact material is improved to allow more than one downflow pass of fluid through the tubes by providing upper and lower vertically aligned partition members to divide the upper and lower tube end chambers into isolated compartments and by using an empty tube to allow upflow communication between adjacent compartments.  In a two compartment configuration, the upper and lower tube end chambers are each partitioned in half, but the lower partition member has a screened port to allow fluid from the first compartment to reach, and move upwardly through, an empty tube(s) in the second compartment which is isolated from the other tubes in the second compartment at its bottom end but not at its top end.

Abstract: CMOS TRANSCONDUCTANCE CIRCUIT WITH TRIODE MODE INPUT          Abstract A transconductance circuit (10) has its signal input terminals (22,28) at the gates of a pairs of MOSFETS (16,22; 32,38) which are forced to operate in the triode mode.  The outputs of the triode mode MOSFET pair are fed to a cascode transistor (18,20; 34,36) for treatment as a differential signal.  The differential output (28; 40) of the cascode transistors is highly linear with respect to the input signal at the gates of the triode mode transistors.  Bias voltages for the gates of the cascode transistors are generated by a bias network (14).  The transconductance circuit 12 includes a cross-coupled set of compensation capacitors (62, 64; 66, 68) formed from devices with the same geometries as the triode mode transistors to compensate for high frequency loss due to the Miller effect in the input transitors.

Abstract: "RACK FOR STORING AND DISPENSING ROLLED FLOOR COVERING"          ABSTRACT OF THE DISCLOSURE          A rack for supporting a plurality of rolls of sheet material particularly floor covering is defined by a frame structure carrying two chains one at each end with the chains arranged to rotate around upper and lower chain wheels.   The chains rotate in synchronism with support hooks carried on the chains and aligned trans-versely of the chains.   A bar can be hooked onto the support hooks to receive a roll of the floor covering. The bar can be lifted into place by a lift mechanism in the form of an elongate bar with an upper and lower hook so the upper hook can engage over a previous bar and a lower hook can lift the intended bar to a position adja-cent its receiving hook.   An overcenter linkage then is used to reduce the length of the bar to lift the new bar into engagement with its  respective hook.   A wind up mechanism is attached to the frame at a forward station and comprises a pair of stub rollers one of which is rotated by a hand crank and expandable thereby to engage a tube and wind up material withdrawn from one of the rolls.    A measuring  device  and transversely moveable knife blade are attached at the wind up station.

Abstract: ABSTRACT OF THE DISCLOSURE      Electroless metal plating solutions are formulated and controlled to provide high quality metal deposits by establishing the intrinsic cathodic reaction rate of the solution less than 110% of the intrinsic anodic reaction rate. Methods are provided to formulate electroless copper plating solutions which can deposit copper on printed wiring boards of quality sufficient to pass a thermal stress of 10 seconds contact with molten solder at 288 °C without cracking the copper deposits on the surface of the printed wiring boards or in the holes. The ratio of the anodic reaction rate to the cathodic reaction rate can be determined by electrochemical measurements, or it can be estimated by varying the concentration of the reactants and measuring the plating rates.
