Abstract: PROCESS FOR THE PRODUCTION OF HIGHER ALKYL        ACRYLATES AND METHACRYLATES      (D#71,200-DTA-69-F) ABSTRACT OF DISCLOSURE A process for the production of higher alkyl acryl-ates and methacrylates having reduced color numbers and con-taining minimum quantities of polymerization inhibitors and other impurities, wherein the alkyl chains contain 3 or more carbons, by the transesterification of methyl acrylate or methacrylate with alkanols of 3 or more carbons in the pres-ence of a titanium alcoholate as transesterification catalyst and also in the presence of polymerization inhibitor combina-tion and entraining agent for removing the methyl alcohol by-product.  The transesterification is carried out by passing an oxygen-containing gas through the reaction mixture.  In recovering the higher alkyl acrylates or methacrylates the resultant reaction mixture is subjected to a steam distillation.                  -I-

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a device for welding cylindrical elements headwise to one another.  The welding is achieved by subject-ing the cylindrical parts during the welding operation to a radial pressure near the welding area, which radial pressure may be directed inwardly.  The device employed comprises an elastic ring to be arranged around the parts to be welded, said ring being accommodated in a sleeve in which a conduit for the supply of pressurized medium to the space between the ring and the sleeve is arranged.  The ring  can be displaced laterally so as to engage and align both of the cylindrical elements.          The elastic ring has a circumferential groove at the welding site such that the ring does not contact the elements near the welding site.          Vent channels communicate with the circumferential groove.

Abstract: ABSTRACT OF THE DISCLOSURE   A chair of the reclining type has a pair of spaced rollers in channel members at each side of a platform to permit the chair to recline when moved to its forward position. A first link mechanism connects the back seat and chair frames with a roller on each side disposed within the channel between the rollers on the chair. A second link mechanism is formed by a pair of links having a roller between the rollers on the chair frame at each side thereof to be actuated by the first link mechanism to operate the chair frame through lazy tong links. This causes the first link mechanism to move a substantial distance greater than the chair frame due to the rollers moving together and those on the links moving the additional distance between said chair frame rollers.

Abstract: GLIDE SLOPE WARNING SYSTEM WITH         A VARIABLE WARNING RATE     ABSTRACT OF THE DISCLOSURE In a system where the aircraft's distance below a radio glide slope is compared with the aircraft's altitude above ground to generate either an advisory voice warning or a command voice warning depending upon the aircraft's altitude and distance below the radial glide slope beam, the repetition rate of the advisory voice warning is varied as both a function of distance below the radio glide slope beam and of altitude in order to generate advisory warnings at a rate reflecting increasing danger to the aircraft.  This is accomplished by integrating the glide slope deviation signal over time and comparing it with a radio altitude signal so as to generate a signal for triggering the advisory warning as a function of the glide slope deviation and the radio altitude, thereby generating the advisory warnings as a function of decreasing radio al-titude and increasing deviation from the glide slope.

Abstract: DIGITAL ERROR COUNTING CIRCUIT by Ralph LeRoy Kline ABSTRACT OF THE DISCLOSURE            An initial error indicated by a pulse at the binary input is applied through a gating circuit to trigger a monostable multivibrator one-shot to start a timing interval.  The output of the one-shot is applied to a second gating circuit which inhibits the first gating circuit to prevent retriggering of the one-shot.  Subsequent error pulses are then applied directly to a counting mechanism which counts the errors which occur during the predetermined time interval established by the one-shot.          An acceptable error density is established by the predetermined time interval for the one-shot in relation to the number of errors that would occur during this predetermined time interval.  If the number of errors which occur exceeds the acceptable error density, the counting circuit puts out a signal which may be applied to an alarm (or framing) circuit.  Once the error counter produces an output, i.e., exceeds the acceptable error density, the counter applies a binary indication to the second gating circuit which causes the first gating circuit to retrigger the one-shot. Further, each error pulse which occurs before the one-shot times out will now trigger the one-shot. In order for the circuit to reset, an error-free period, equal to the period of the one-shot, must occur.

Abstract: SINGLE AMPLIFIER NETWORK FOR SIMULATING AN FDNR CIRCUIT by Charles E. Schmidt ABSTRACT OF THE DISCLOSURE      The series combination of an FDNR and a resistor is simulated across a pair of terminals of a one-port network which includes a single differential input operational amplifier.  One terminal of the network is connected through a first resistor and a second resistor to associated first and second differential inputs of the amplifier. The output of the amplifier is connected through a third resistor to the first input of the amplifier, through the series combination of a first capacitor and a fourth resistor to the second input of the amplifier; and through the series combination of the third resistor and a fifth resistor to the other terminal of the network which is connected to ground.  This other terminal is also connected through a second capacitor to the second input of the amplifier.  With the capacitances of the capacitors normalized to unity, the product of the normalized resistances of the second and fifth resistors being equal to the product of the normalized resistances of the first and fourth resistors, and the normalized resistances of the third and fifth resistors being the same value, the impedance presented across the one port of the network corresponds to that of an FDNR in series with a resistor.

The outlet temperature of the gas in the last zone (from which the finally dried material is removed) is greater than that, in decreasing sequence, of that from the preceding zone(s) when the solid material being dried is below its critical moisture content which is, of course, when the moisture rate is limited by its diffusion within the material being dried.  Otherwise, enough flow can be put into the system to cause desired temperature effects with heat trans-fer limitations then being the controlling factor.
