Abstract: ABSTRACT OF THE DISCLOSURE: A process for the manufacture of polymers of net shaped crosslinked structure and with uniform length of the crosslinks. In this process, polyfunc-tional organoalkali metal compounds which have been manufac-tured by reaction of divinylbenzene with low molecular weight organoalkali metal compounds, are reacted direct, or after prior reaction with anionically polymerizable monomers, with bifunctional or polyfunctional coupling agents. The polymers of net-shaped crosslinked structure have macroporous pro-perties and can be employed, for example, as gels in gel per-meation chromatography or as carriers in the synthesis of peptides.

Abstract: ABSTRACT OF THE DISCLOSURE         Improved chain-stopped polyester plasticizers for polyvinyl chloride homopolymers and copolymers are provided. The chain-terminated polyester has an average molecular weight between 1500 and 10000, and is obtained from the esterification of (a) an alpha-omega alkanedioic acid containing from 4 to 12 carbon atoms and (b) a branched chain dihydric alcohol containing from 4 to 10 carbon atoms and having only primary and secondary hydroxyl groups with (c) 3 to 15 mol percent, based on the total organic acids, of an aromatic monocarboxylic acid containing from 7 to 20 carbon atoms.  The plasticizers show little or no tendency to migrate from PVC, yet they are readily processable with the PVC.  While being extremely compatible with PVC the present plasticizers bave very low affinity for ABS and poly-styrene resins and therefore can be used in applications where plasticized PVC comes in contact with these other resins.

Abstract: ABSTRACT OF THE DISCLOSURE Two substantially identical servo channels, coupled through a differential mechanism, position an attitude control surface of an aircraft in response to a common command signal applied to both channels.  The common command is coupled to each channel through separate displacement and rate limiting devices to limit the attitude displacement and rate of change of attitude commands about the associated aircraft axis.  In the pitch axis a separate normal accelerometer controls each command rate limit so as to  prevent excessive pitch maneuvers due to the common command source.  Redundant polarity compar-ators are included for comparing the polarity of the incre-mental load factor with the polarity of each servo channel output and for applying a brake to clamp the output of a  failed servo channel when the polarity of the incremental load factor agrees with the servo motion direction and the incremental lead factor exceeds a predetermined level, thus allowing the valid servo to assume control of the aircraft for a limited time until the pilot disconnects the system in response to monitoring circuits which operate alerting devices.

Abstract: ABSTRACT OF THE DISCLOSURE      A battery plate grid comprising a composite molded plastic support and interlocking metallic fingers having an integral lug.  The grid is produced by first molding the lug and metallic fingers while forming a plurality of connecting points along the fingers and the lug in first and second mold halves.  The connecting points are forced by utilizing retractable pins within the first mold half. After casting of the metallic fingers and lag of the grid, the second half of the mold is withdrawn while the metallic casting remains in the first half of the mold.  A third mold half is then positioned adjacent the first mold half and has a portion of the desired plastic supporting pattern forced therein and the plastic material is injected.  The pins are retracted prior to or during the injection of the plastic material permitting the plastic to flow into the space vacated by the pins in the first mold half and form interlocking joints with the metallic structure.  The first and third mold halves are then separated and the finished composite grid may be removed.
