Abstract: ADAPTIVE BRAKING SYSTEM WITH SPECIAL CONTROL             FOR SLIPPERY SURFACES                   ABSTRACT OF THE DISCLOSURE         An adaptive braking system for a vehicle having fluid pressure operated brakes includes a skid detecting circuit for generating a signal when an incipient skidding condition is detected, a pressure command generator which is responsive to the skid detecting signal for generating a pressure command signal proportional to the optimum fluid pressure level in the vehicle's brakes, and a duty cycle translator responsive to the pressure command signal to actuate the brake pressure modulator.  Of course, since the pressure level in the vehicle brakes cannot drop below zero, the value of the pressure command signal generated by the pressure command generator cannot drop below a predetermined level.  If the skid detecting circuit continues to generate a signal indicating an incipient skidding condition after the pressure command signal is at its lowest level, the subsequent brake pressure increase which is normally initiated upon termination of the skid detecting signal is delayed for a time period which is a function of the time period in which the skid detecting signal was generated after the value of the pressure command signal had dropped to the lowest permissible level.

Abstract: ABSTRACT OF THE DISCLOSURE:-Procedures are disclosed for producing both core-clad-ding optical fibers and self-focusing optical fibers from porous germanite and/or silicate glasses obtained after phase separation and removal of the soluble phase.  A glass which is separable into at least two phases one of which is soluble, is heated to cause phase separation.  The soluble phase is leached out removing undesired impurities.  The pores are collapsed and this glass is used to produce cores and/or cladding layers, or self focusing fibers.  Preforms of the porous glass have their interconnected pores stuffed with a dopant.  In the production of core-cladding optical fibers, the dopant modifies the index of refraction of the core and/or cladding so that the index of refraction of the core is greater than that of the cladding.  The control of this index of refraction can be accomplished by addition of non silicate network formers such as GeO2 to the original melt before phase separation.  These network formers will stay in the insoluble phase.  In producing self-focusing fibers, the dopant may be non-uniformly deposited in order to produce a radial gradient in the index of refraction, or sodium or potassium ions may be ion exchanged into the glass for a portion of a dopant containing lithium or thallium to produce such an index of refraction gradient.

Abstract: Abstract of the Disclosure Disclosed is a method of t.d.m. frame synchronization using variable synchronizing words.  The method is applicable to t.d.m. systems with either bit-wise or envelope-wise interleaving.  Whenever a number of marker bits forming synchronizing words have been disturbed. The frame synchronization may go out of step.  The present invention is to be seen in setting forth a method guaranteeing a stable frame synchronization, even if individual marker bits are disturbed.  This is achieved in that the t.d.m. signal is utilized for synchronization in its non-synchronous state, whereas in its synchronous state the synchronization is effected by locally produced marker bits.

Abstract: FLUID COOLING OF GLASS MOLDS            ABSTRACT OF THE DISCLOSURE          The cooling of glass forming molds is accomplished by providing a plurality of radially spaced passages either in the mold itself or in a mold holder in good heat transfer relation-ship to a mold insert.  The passages extend vertically and may either be completely through the mold or may extend substantially to the lower end of the mold.  These passages are radially in-sulated by the compaction of a particulate material such as 316-L Stainless Steel Compacting Powder, with the compressed material being carefully packed within the passage and in sur-rounding relationship to a coaxially positioned metal tube.  The metal tube provides access for the circulation of a liquid cool-ant.  The thickness of the particular material, its degree of compression and its composition and the relative position thereof with respect to cavities of the glass forming mold, will deter-mine the heat flow characteristics of the mold and/or mold holder.          Proper selection of the parameters involved results in the desired temperature at the molding surface of the mold.

Abstract: PLURAL CHANNEL ERROR CORRECTING METHODS AND MEANS USING ADAPTIVE REALLOCATION OF REDUNDANT CHANNELS                 AMONG GROUPS OF CHANNELS  Abstract of the Disclosure Where data is recorded on logically independent sets of parallel channels or tracks, the correction of error of very long (infinite) length cannot be advantageously treated by conventional coding methods unlike finite length error such as single shot or burst noise.  To ensure the correction of channels in error from data recovered from a multi-channel storage medium, a fixed number of channels per set are dedicated to error checking bits.  In this invention, more than the usual number of channels in error in any one set are made correctable by adaptively reallocating the unused redundant channels in the other set.  This is accomplished by encoding and recording in the first redundant channel in. each set vertical parity checks limited to that set while encoding and recording in the second redundant channel of each set, the parity of data taken over both sets of channels in a predetermined positively or negatively sloped direction.          With this type of parity information so recorded, then the data obtained from up to three known erroneous channels in any one set may be corrected, provided that two sets together aggregate not more than four channels in error.  Advan-tageously, the vertical and cross-parity checking infor-mation can also be used to generate an internal channel-in-error pointer for the first erroneous track in each set.          Additionally, this data can be made to yield a second internal channel-in-error pointer in at least one of the sets.          Lastly, error patterns are identified upon decoding at the intersection of at least two error syndromes one of which is derived from cross-parity checking bits.

Abstract: ELECTROGRAPHIC ELEMENT PROVIDED WITH             ELECTRICAL CONNECTION MEANS            Abstract of the Disclosure An electrographic element comprising an electri-cally insulating support, an electrically conductive layer overlying the support, and an electrically insulating photo-conductive layer overlying the conductive layer, is provided with electrical connection means adapted to establish electri-cal connection between the conductive layer and a grounding or biasing member which engages a surface of the element while the element is in motion.  The electrical connection means comprises a region of dispersed particulate electrically-conducting material within a non-recording portion of the element which extends from the surface of the element into contact with the conductive layer.  This region defines on the surface of the element an elongated stripe which is longi-tudinally disposed  in the direction of motion of the element and which encompasses an elongated longitudinally disposed groove.  To form the region of dispersed particulate electri-cally-conducting material, an elongated groove extending from the surface of the element at least to a position proxi-mate to the conductive layer is formed in the element and an imbibable composition comprising the particulate material is then applied to the surface of the element as an elongated stripe which encompasses the groove.  The groove serves to promote the imbibition of the particulate material into contact with the conductive layer so as to form an electrical path from the conductive layer to the stripe on the surface of the element and thus provide electrical connection with the grounding or biasing member which engages the stripe.
