Abstract: ABSTRACT OF THE DISCLOSURE                A mechanical device for visually indicating the tension in a monitored bolt or the like.  The device will visually indicate if the monitored bolt is subject to greater than a predetermined maximum tension or is subject to less than a predetermined minimum acceptable tension.  The device will also give visual indication  generally proportional to the tension in the monitored bolt, when the tension in the monitored bolt is at less than the predetermined maximum but more than the predetermined acceptable minimum.  The device includes a spring washer, preferably a helical washer, which 's inserted inbetween the head of the bolt and the surface or backing plate against which the head of the bolt will bear for substantially resilient compression therebetween.  The washer is selected with a spring constant such that the washer will be substantially flattened between the bolt head and the the plate only upon the applicatic of a tension to the bolt exceeding the predetermined maximum. The washer includes a pivot member, preferably a pivot pin, which will move axially away from the plate as the washer expands in response to less than predetermined maximum tension in the bolt. The pivot member with be axially spaced a known distance from the plate when the tension in the bolt is equal to the predeter-mined acceptable minimum tension. An elongated indicating member or flag, is pivotally mounted at one end thereof to the pivot member.  The indicating member includes a surface or face which will engage the plate when the washer is flattened thereby maintaining the indicating member in a first position and which i will totally disengage the plate when the pivot member is axially spaced by the known distance from the plate to allow the indicating member to pivot under the influence of gravity to assume a second position.  The indicating member will assume a position intermediate the first and second positions when the washer is intermediate the flattened condition and the condition whereat the pin is at the axial distance from the plate.

Abstract: ABSTRACT OF THE DISCLOSURE           A reaction vessel for regenerating particulate adsorbents has a bottom outlet and top inlets for admission of the adsorbent to be regenerated by being heated to a regeneration temperature, and for a particulate regenerating material at a temperature above the regeneration temperature.  The mixture of the adsorbent with the regenerating material forms a bed in the reaction vessel and is contiuously withdrawn through the outlet so that the bed descends toward the latter and is replenished from above under the formation of a cone at the upper region of the bed.  A plurality of tubular baffles coaxially surrounds the inlets which are also coaxial with one another, each of the tubular baffles penetrating into the bed in the region of the cone and retards the flow of the particles of the mixture down the slope of the cone in that the particles must pass underneath the baffle to flow to the next baffle.  The bed may be confined between a plurality of axially overlapping spaced tubu-lar guide baffles located in the interior of the reaction vessel with a spacing therefrom.  At least one partition may be provided between one of the guide baffles and the vessel, subdividing the chamber between the vessel and the guide baffles into two compart-ments from which gases which develop during the regeneration of the adsorbent are separately exhausted.

Abstract: PROCESS FOR THE REMOVAL OF VINYL                  CHLORIDE FROM GAS STREAMS     Inventors:  Piyush J. Patel, Clay G. Thompson, Edward J. Hourihan, and Carl S. Stutts, citizens of the United States of America, residing at Somerville, County of Somerset, State of New Jersey; Milltown, County of Middlesex, State of New Jersey; Mt. Holly, County of Burlington, State of New Jersey; and Houston, County of Harris, State of Texas, respectively.     Abstract of the Disclosure Vinyl chloride is removed from gas streams that contain from 10 ppm to 100 mole percent of vinyl chloride by passing the gas stream through a bed of coconut shell-derived or petroleum-derived activated carbon.  The exit gas stream contains less than 5 ppm of vinyl chloride.       The vinyl chloride-saturated carbon is treated with steam at 100°-150°C. to desorb the vinyl chloride, which is then recovered.  The wet carbon is contacted with an inert gas at 90°-150°C. until its water content is less than 1% by weight; the hot dry carbon is cooled to ambient temperature by contacting it with a cold inert gas.  The regenerated activated carbon is then used to remove additional vinyl chloride from the gas stream.   The vinyl chloride adsorption-carbon regeneration cycle can be repeated for long periods of time without loss of adsorptive capacity of the activated carbon or formation of polyvinyl chloride on the surface of the carbon.

Abstract: CHARGE-TRANSFER BINARY SEARCH GENERATING CIRCUIT               ABSTRACT OF THE DISCLOSURE   A bucket brigade circuit is described for generating a sequence of packets of charge carriers of the form QR/2, QR/4, QR/8....QR/2N where N is an integer.  The charge packets thus generated can be employed in combinations in either digital-to-analog or analog-to-digital converters.  The charge generation circuit requires two equal capacitors which are used for charge redistribution.  To obtain accurate quantities of charge in the generated charge packets the capacitors employed should be large, however the use of large capacitors results in low operating speed because of the large charge transfer time constants involved.  The described circuit provides a scheme to reduce charge transfer time constants and therefore obtain greater speed while still permitting the use of large capacitors for high accuracy.  The circuit includes a small coupling capacitor connected in series with one of the charge redistribution capacitors to produce a total capacitance which is equal to or smaller than the coupling capacitance.  The sequence of charge carriers produced by the circuit can be injected into either a bucket brigade circuit or a charge-coupled-device circuit for use, for example, in digital-to-analog and analog-to-digital converters.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to starch acrylamides containing polymerizable pendant acrylamide groups. The hydrophilic or hydrophobic properties of the starch can be altered or modified by the acrylamide groups or the type of starch chain. The starch acrylamides can be homopolymerized or copolymerized with other ethylenically unsaturated monomers as well as other cross-linking reagents to provide water-resistant, clear, flexible coatings or shaped articles. The hydrophilic starch acrylamide hydrolyzates herein readily disperse into water at a high solids level to pro-vide low-viscosity pastes which may be used as a vehicle to pre-pare flexible, water-insoluble starch-based coatings. The starch acrylamides may be prepared by etherifying a starch with N-methylol acrylamides in the presence of an acid catalyst and a polymeriz-ation inhibitor.
