Abstract: RATCHETING PIPE WRENCH     ABSTRACT OF THE DISCLOSURE An improved ratcheting pipe wrench which includes a first toothed jaw formed on a first member and a second toothed jaw rotatably carried by a second member provided with an elongated handle portion.  The first member has a shank portion which is slidably receivable in a guide way formed in the second member.  The guide way is configured to provide clearance to the shank portion of the first member so as to permit both longitudinal and pivotal, or up and down rocking movement of the first member relative to the second member.  With this construction the jaws of the wrench can readily be separated to accomodate a pipe, nut or bar (work piece) of various sizes.  Further, with work piece in position between the toothed jaws, pressure exerted on the handle portion of the second member will tend to increasingly tighten the jaws about the work piece to provide a positive gripping action.          Conversely, release of pressure on the handle portion will cause the jaws to loosen so that the wrench can readily be ratcheted to a new gripping position.

Abstract: ABSTRACT   A digital multi-phase multi-level modulation communication system is described.  The transmitter multi-level multi-phase modulates a carrier wave with at least four trains of first digital signals each including a first frame signal of a pattern sequence, and transmits the thus modulated carrier. The receiver performs a coherent detection and multi-level decision on the modulated carrier wave to demodulate second digital signals corresponding to the first digital signals.  Frame synchronization and timing is established in the receiver in response to at least one of the second digital signals and a second frame signal corresponding to the first frame signal is extracted from the second digital signals in response to the frame timing.  The trains of the second digital signals and their polarities are changed in response to the second frame signal and the second digital signals to reproduce the first digital signals from the second digital signals.

Abstract: A B S T R A C T         A time assignment speech interpolation system includes a variable length speech buffer for temporarily storing sampled signals until a transmission facility becomes available.  Signals on input speech channels are converted into digital samples.  If a transmission facility is available, the digital samples are reconstituted into analog signals which are transmitted over the facility.  If no facility is available, digital samples are stored in a digital memory for a variable length of time until a transmission facility becomes available.          Digital samples are retrieved from the memory in chronological order of their time of arrival at the memory.  The variable length memory accommodates a short term overload of input signals to provide flexible buffering.  Means are provided for bypassing the sampled signals from a particular input channel around the buffer whenever both a facility is available and no sampled signals from that channel are stored in the buffer.

Abstract: ABSTRACT     A segment display system where ultraviolet energy is generated and contacts with fluorescent material coat-ings to provide a visible output through fluorescent excitation of the fluorescent material coatings.  Ultra-violet energy is generated through the ionization of metallic atoms from a metallic coating which is formed on through opening sidewalls of slots defining a cathode mechanism.  The slot through openings are aligned with fluorescent material coatings formed on a display panel member.  Below the cathode mechanism is a common anode element.  Each of the metallic coatings formed within each of the slot through openings is coupled to an external electrical source in a manner similar to the anode element being so coupled.  The segment display system is formed into a monolithic structure which includes an internal chamber within which an inert gas is introduced.  Electri-cal energization of the cathode elements and the anode element result in ionization of metal atoms emitted from the metallic coating.  The ionization process provides for ultraviolet radiation which is directed to the fluores-cent material coating.  The coatings are generally linearly extended and are formed into a predetermined pattern in order to provide visible information output such as numerical digits.
