Abstract: ABSTRACT OF THE DISCLOSURE           A circuit for the asynchronous measurement of the phase jitter of an incoming signal, at least a part of which is digital, includes a differentiator for sensing pulse transitions of the incoming signal and a periodic function generator resetable by the differentiated pulses.  Function valves generated by the function generator coincident with the differentiated pulses are added together and averaged to form an average value of phase jitter based on the number of incoming signal transitions that are sensed.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to the reduction of polymer buildup on the inner surfaces of a polymeriza-tion reactor by applying a polymer buildup resistant coating to the inner surfaces thereof, the method or process of applying said coating being the subject of this invention.  An approximate monolayer coating on the inner surfaces of the reactor results from applying thereto an aqueous or organic solvent solution of the coating material by means of vinyl chloride in vapor form.  The coating material is an organic compound or polymer which is capable of resisting polymer buildup thereon.  As examples of such coating materials, there may be named the polyaromatic amine, self-condensed polyhydric phenols, tannic acid and tannates, various dyes, such as nigrosine, and the like, etc.  When using vinyl chloride to apply the coating material, the same reaches the inner reactor surfaces in the form of a mist.  When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal CH2=C < grouping, and mixtures thereof, in the presence of said coating, polymer buildup on the inner surfaces of said reactor is substantially eliminated.

Abstract: Abstract of the Disclosure A folding connector mechanism is housed within a single stile which  is  divided  into major and minor parts.   The major part constitutes the lower section of the crutch and the minor part is a portion of the upper section of the crutch.  When the crutch is in its use position the weight of  the  user  is  transmitted  by  the  folding  connector mechanism directly from the lower end of the minor part of such stile to the upper end of the major part of such stile and  is not  carried by any cross pins or the like.   The folding  connector  mechanism  includes  a  lock  button  for locking the two sections of the crutch together when the crutch  is  in  its use  position.   The  lock  button  is positioned  closely  adjacent  the handle of the crutch so that the user can grasp the handle with one hand with the thumb of such hand on the lock button while grasping the lower section of the crutch with his other hand.  He then depresses the button while pulling the two sections of the crutch apart.   This moves the folding connector mechanism out from a housed position,  permitting its operation for folding the crutch.

Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus is disclosed for drilling a pilot hole and subsequently enlarging the pilot hole in earth formation A dual concentric pipe string is used for circulating air downwardly through the outer pipe, through a pilot bit and upwardly through the bore hole outside the pipe string to bail cuttings, during drilling of the pilot hole.  The air pressure expands the cutters of an expansible bit while a limited portion of the air supplied cools the cutters.          After the cutters are fully expanded, additional air is utilized to clean and cool the cutters.  Air is returned through the inner pipe of the dual concentric pipe string.          A venturi device is utilized to induce return flow through the inner pipe during enlargement of the hole to vacuum residue when enlargment is completed.  The dual concentric pipe string is made up of lengths of pipe providing threaded, sealed joints.
