Abstract: ABSTRACT OF THE DISCLOSURE      An axial thrust bearing includes a plurality of circumferentially arranged segments.  The segments are constrained in the circumferential direction by means of support plates disposed therebetween.  The segments are elastically supported by means of individual spring elements mounted in a bearing body.  The segments are provided with support ribs having tilting edges.  The support ribs are supported between the support plates, and the tilting edges are supported against the spring elements.   As a result, friction between the segments is minimized.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a process for dewatering an aqueous latex containing rubber particles grafted with alkenyl aromatic and alkenyl nitrile monomers and emulsi-fied with an anionic surfactant wherein alkenyl aromatic and alkenyl nitrile monomers are dispersed in said latex along with a cationic surfactant in an amount sufficient to deemulsify said grafted rubber particles.  The grafted rubber particles are extracted from the aqueous phase into the monomer phase as a liquid oil phase, with the aid of the cationic surfactant, said aqueous phase form-ing a separate water phase essentially free of said oil phase followed by separating said water phase from said liquid oil phase.

Abstract: VIDEO PLAYER AND/OR RECORDED              WITH HADAMARD TRANSFORM                         ABSTRACT      An apparatus for performing a Hadamard transform on video data for compression of data to be recorded and decompression of data read from a record for dis-play achieves the necessary high rate by means of two or more adders and two subtractors operating in para-llel.  A store that holds the data during successive passes through an arithmetic unit has accessing cir-cuits and a set of registers and associated gates that fetch and store the data in a repetitive sequence that simplifies storage accessing.  Data is processed in units that represent for example eight lines of a television picture and an output buffer is provided for the decompressor of a video disk player that receives data as it is processed and holds previously processed data unit by a storage accessing circuit that minimizes the amount of buffer storage that must be provided in the player.

Abstract: DEMAND ASSIGNMENT TECHNIQUE FOR TDMA      SATELLITE COMMUNICATION NETWORK                    ABSTRACT            In a time division multiple access satellite communi-cation system, a reference station which allocates channel capacity also regulates demand by the ground stations for that capacity.  The regulation is accom-plished by means in the reference station for trans-mitting limiting, blocking and revocation messages to the ground stations and means in the ground stations responsive to these messages to regulate the processing of input service requests.  The limiting messages notify the ground stations to limit their channel usage to the channels required in the last demand message transmitted but not to exceed their last channel assignment.  The blocking messages instruct the ground stations to unconditionally block any new requests for service on their input ports, rather than counting such calls as increments of demand, and thereby effectively reduce the aggregate demand in the system.  When the reference station observes that a sufficient decrease in channel requirements occurs, resulting in an increasing spare capacity, it revokes the previously communicated blocking messages by a revocation message.

Abstract: Abstract:    The present invention relates to a converter control apparatus.  Two rectifiers and two inverters are operated and are connected in parallel by common transmission lines. These rectifiers and inverters are controlled by independent control apparatuses, respectively, which can selectively apply either constant current control or constant voltage control.  The control apparatus of each converter has bestowed thereon reference value of a current flowing through the particular converter and the reference value of a terminal voltage of the particular converter.  A signal for lowering the current reference value is added to the control apparatus of one or all of the converters which are to be operated as the inverters.  A signal for essentially rendering the terminal voltage of the converter smaller than the voltage reference value is added to the control apparatus of the converter which is to be operated as the converter for determining the voltage of a direct current system.
