Abstract: ABSTRACT           A suspension assembly is provided for suspending gypsum board panels from a horizontal support member.  The plate portion of the suspension assembly has panel piercing tangs of a novel twisted conformation projecting rearwardly to affix the plate to the panel.  A narrow neck portion of the plate forms channel means to receive the upper portion of a separate suspension clip.  The lower portion of the clip is inclined outwardly to engage the horizontal support member.  A plurality of transverse lines of weakness comprising slots and notch means extending substantially across the width of the neck portion of the plate are designed such that when the gypsum board panel is suspended from the support member, the load applied between the clip and the plate causes the neck portion of the plate to bend outwardly from the panel along said lines of weakness, while the upper and lower plate portions remain affixed to the panel.

Abstract: ABSTRACT     Prior to the solvent extraction of uranium from wet-process phosphoric acid the pretreatment of acid is necessary for an efficient and successful operation.  The suspended solids in the acid solution is first removed effi-ciently with an inclined-corrugated-plate separator without addition of chemical reagents and then the organic matter in the solution is extracted with kerosene.  A very clear acid solution is obtained.  The concentrated sludge can be returned to the phosphoric acid plant and the crud organic matter form-ed as a third phase between the organic and the aqueous phases produced in the kerosene washing in the settler chambers is withdrawn and treated in a centrifugal separator to recover the Kerosene.  The recycled kerosene can be used as a good diluent in the subsequent uranium solvent extraction process.

Abstract: IMPROVED ACCELERATION MONITORING SYSTEM FOR        PROTECTING GAS TURBINE AGAINST DAMAGING OPERATION AT RESONANT SPEEDS                    ABSTRACT OF THE DISCLOSURE A fuel control schedules fuel to a gas turbine to produce a scheduled speed profile during startup.  The scheduled speed profile is continuously compared to actual turbine speed during startup, and the difference is com-pared to an alarm setpoint and a trip setpoint.  Normally, temperature and surge limit controls prevent the turbine from accelerating too fast; and, if the turbine is accel-erating too slowly, an alarm output is generated when the actual/desired speed difference reaches the alarm setpoint and the turbine is tripped when the actual/desired speed difference reaches the trip setpoint.

Abstract: ABSTRACT          An expandable tire building drum is provided with hinged drum shoulder segments that present, when the drum is in its expanded position, a bevelled shoulder contour for supporting the thickened portion of the tire band next to the bead.  This bevelled contour results in a greater radius or curvature for the thickened tire portion that extends around the drum shoulder, which makes it easier to pass a stitcher wheel over this portion of the tire, and to achieve a more uniform layering of the tire components next to the bead of the tire.  When the drum is in its retracted positions the hinged drum shoulder segments are lifted to positions wherein they provide support for the carcass plies of the tire when they are first laid across the drum segments and the bead turnover bladders.

Abstract: ABSTRACT OF THE DISCLOSURE      There is presented a new process for producing homopolymers and copolymers of vinyl and vinylidene halides by means of the suspension polymerization procedure.  In this new process, the reactor is run a few degrees warmer than normal for the first part of the reaction and then followed by a steadily decreasing temperature throughout most of the rest of the polymerization in order to linearize the reaction rate.  This allows one to charge more initiator and/or monomer to the reactor thereby increasing produc-tivity per unit of time.

Abstract: METHOD AND APPARATUS FOR OBTAINING A       COMPOSITE FIELD RESPONSE TO A VARIABLE      SOURCE ARRAY USING WEIGHTING COEFFICIENTS              ABSTRACT OF THE DISCLOSURE      A multi-channeled digital seismic field stacking system is disclosed for obtaining the composite response to a vari-able source array.  A variable source array is synthesized by applying preselected weighting coefficients to the seismic signals produced in response to a selected number of surface energy impulses.  The seismic signals produced by these impulses are amplified, multiplexed and digitized to obtain digital samples to which are applied the weighting coeffi-cients.  A digital multiplier is used to multiply each digital sample by a weighting coefficient to obtain a weighted digital sample.  Each digital sample is multiplied by two weighting coefficients, a partial and a final.  The partial weighted samples from each of the impulses are summed together to form a partial stack, while the final weighted samples are summed together to form a final stack.  The variable source array which is synthesized covers two station intervals.  At each station, the partial stack represents the first half of a variable source array, while the final stack represents a complete source array covering the two previous station intervals.  At each station, the final stack is recorded on magnetic tape as a seismic field record, and the partial stack is transferred to the final stack for summation with the final weighted samples for the last half of the next variable source array.

Abstract: TITLE          CONTROL WINDING FOR A MAGNETIC LATCHING REED RELAY                 ABSTRACT OF THE INVENTION           A magnetic latching reed relay including a single continuous control winding disposed about an encapsulated reed switch having a pair of reeds constructed of a remanent magnetic material.  The reeds are normally biased in an open position.  When a first pulse of current, of a certain amplitude, is applied to the control winding a magnetic flux field is generated which magnetically saturates the reed blades, producing magnetic poles of opposite polarity at the contacting ends of the reeds which overcomes the normal mechanical bias of the blades, closing the contacts.  A second pulse of current of an opposite direction and of approximately half the amplitude of the first pulse is then applied to the control winding and a reverse magnetic flux field is generated which is insufficient to magnetically saturate the reed blades and the magnetic polarity established thereby being also insufficient to over-come the normal spring bias of the blades, thus allow-ing the blades to return to the normal or open position.
