Abstract: A delta modulator automatically adjusting the slewing rate is disclosed. In the absence of a transition in the output data of a delta modulator, a parameter used for the integrator of the delta modulator is increased. When the comparator of the modulator indicates that the feedback signal of the modulator has overshot the input signal, the parameter is decreased or reversed until the two signals are approximately equal as signalled by a 50% duty cycle.

Abstract: A communication network signalling system couples a signal transfer point to a plurality of channel banks through links which include link monitor and test units. The link monitor and test units, which monitor the links in a passive, non-obtrusive manner and which at the same time are capable of being serially coupled into the link so as to insert signals in series with the link and to otherwise accomplish in-depth link testing and analysis, each include a pair of channel units coupled to opposite portions of an associated link and which are coupled together through a metallic through connection in the form of a normally unenergized relay. The metallic through connection provided by the relay maintains the signal path through the link during a variety of fault conditions, while at the same time permitting electronic portions of the channel units to be cross-connected to accomplish monitoring and testing functions.

Abstract: An accompaniment apparatus has a first memory for memorizing a plurality of original accompaniment patterns corresponding to various accompaniment styles, each original accompaniment pattern being composed of a set of parallel part patterns. An editor is operated for designating different ones of the original accompaniment patterns and collecting therefrom a set of desired part patterns to define a free accompaniment pattern which is different than the original accompaniment patterns. A second memory memorizes designated and collected results by the editor for use in reproduction of the free accompaniment pattern. During the reproduction, a pattern length difference or a meter difference among the set of the collected parallel part patterns can be corrected to maintain a consistent progression of the automatic free accompaniment.

Abstract: A pipe corral connector consisting of a pair of bolts having corresponding hingedly coupled first ends, and second, threaded ends. The second end of one of the bolts is provided with a right hand thread while the second end of the other bolt is provided with a left hand thread. The threaded ends of the bolts are brought together with a nut that is internally threaded halfway with a right hand thread and halfway with a left hand thread. The nut provides a turnbuckle-like effect in bringing the two bolts together and tightly joining intersecting or parallel pipes of a pipe corral. The connector eliminates all sharp edges which might otherwise injure a corralled horse. The inside surface of the connector bolts may be serrated or notched to provide increased friction at the point of pipe connection. The nut and one of the bolts may be marked to identify matching thread sense to facilitate determination of the correct orientation of the nut.
