Abstract: ABSTRACT OF THE DISCLOSURE            In a carrier system having a plurality of relatively wide band (or voice) channels which are time-division multi-plexed and represented by N sequential coded pulses for each channel, it is sometimes desirable that the individual pulses of one or more of the relatively wide band channels be used for information of data.  In such past arrangement, only (N - 1) of the pulses were used for transmitting information.          The Nth pulse was reserved as a needed keep-alive pulse to provide proper operation of repeaters in the pulse coded system.  The present arrangement provides means at the trans-mitter for detecting when (N - 1) of the channel pulses are all in an undesired code condition, and transmitting the needed keep-alive pulse as the Nth pulse.  If any one of the (N - 1) channel pulses is in the desired code condition, the Nth pulse can transmit information.  At the receiver, means are provided for detecting when the (N - 1) channel pulses are all in the undesired code condition, and for causing the Nth pulse to continue producing the last representative pulse received.          If any one of the (N - 1) channel pulses is in the desired code condition, the Nth channel pulse represents the information actually transmitted.

Abstract: CYCLIZATION OF PEPTIDES          ABSTRACT OF THE DISCLOSURE    The synthesis of a disulfide cyclic peptide by preparing a non-cyclic peptide containing at least two cysteine moieties in its amino acid chain one of which is protected by an n-alkylthio group, and subjecting such non-cyclic peptide to a procedure in which the non-cyclic peptide is held in solution substantially free of oxygen at a pH of from about 5 to 10 until rearrangement takes place to yield a cyclic disulfide peptide and to displace said n-alkylthio group from said amino acid chain.  The disclo-sure also embraces said non-cyclic peptides as new compounds and the processes by which they are prepared.

Abstract: ABSTRACT OF THE DISCLOSURE           A write clock generator of a digital time base corrector for removing time base errors from color video signals includes a voltage controlled oscillator (VCO) a phase lock loop by which the oscillator output or write clock pulses, after being suitably divided, are compared, as to phase, with the horizontal synchronizing signals and the burst signals separated from the video signals for controlling the VCO on the basis of both comparisons. In order to avoid a lock-out condition of the phase lock loop as a result of variation in the time relationship of the horizontal synchronizing signals and the onset of the respective burst signals, the oscillator output which has been divided to generally correspond to the frequency of the burst signals is employed to produce first and second trains of pulses having the same frequency as such divided output but being out of phase with respect to each other, and one or the other of the trains of pulses is selected, in response to the timing of the burst signals, for phase which comparison with the burst signals of the train of pluses which is substantially out of phase in respect to the latter.

Abstract: ABSTRACT OF THE DISCLOSURE       The joint comprises a pair of parallel tongues of uniform thickness on an edge of one member which are pressed into grooves of uniform width in another member.  The grooves are inclined from top to bottom relative to each other, bending the tongues out of parallelism and thereby locking them in the grooves to form a self-locking joint equivalent to a dovetail joint.  Such tongues on the top and bottom edges of a vertical member are pressed into longitudinal grooves in elongated top and bottom chord members to form an I-beam or truss section. The tongues may be formed on the edge of a board or they may comprise the opposite face sheets on a plywood panel.

Abstract: ABSTRACT    An improved method of making a ceramic mold having a cavity in which a cast product is accurately formed includes reinforcing relatively flexible wax pattern material having a configuration which corresponds to the configuration of the mold cavity.  Supporting the flexible pattern material with a relatively rigid reinforcing member prevents the pattern material from deflecting during removal from the injection die, pattern storage, pattern and gating assembly and dipping of -the pattern in liquid ceramic mold material.  Between dipping steps, portions of a wet ceramic coating are wiped away in areas between portions of the wet coating which will eventually form mold sections.          After the ceramic mold material on the pattern has been dried, the pattern material is destroyed by heating or other methods.          The resulting mold sections are then separated and the rigid reinforcing member removed from between the mold sections.  The separate mold sections are interconnected to form a cavity in which a east product is accurately formed.  In one specific ease, a plurality of mold sections were interconnected to form a circular mold cavity for a turbine engine components.
