Abstract: ABSTRACT OF THE DISCLOSURE In a photosensitive material for electophotography, an intermed-iate layer comprising an organic polymeric photoconductor and a polycyclic aromatic nitro compound at a specific ratio is formed on an electrically conductive substrate, and a top layer comprising, incorporated in a binder, phthalocyanine or a phthalocyanine derivative and the above polycyclic aro-matic nitro compound at a specific ratio is laminated on the intermediate layer.  In this photosensitive material, the dark decay speed is controlled in a range suitable for application to the repeated copying operation and the residual potential left on the exposure area can be reduced to a neglig-ible level.  Accordingly, occurrence of fogging is prevented and the toner transfer efficiency is improved.  Further, this photosensitive material has improved mechanical, chemical and electric durabilities, and therefore, the life of the photosensitive material is remarkably prolonged.

Abstract: Abstract Of The Invention 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 avail-able, 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.

Abstract: ABSTRACT OF THE DISCLOSURE      A style handle for writing and engraving instruments. The base portion of this style, which is gripped when in use, consists of three, essentially-flat surfaces arranged in a triadic spiral at a selected pitch con-forming with an individual's finger grip when the style is held in a normal manner.  So held, the edges of the spiral lie in the grooved portions between the individual's thumb and fingers with the thumb and fingers resting upon the flats of the spiral in a relaxed, natural manner. Also, the inclination of the spiral forms an abutment which permits the style to be held with less pressure when pressing it against a writing or working surface.

Abstract: CATHETER FOR MEASURING INTRAUTERINE PRESSURE            Abstract of the Disclosure A catheter is disclosed for measuring the intra-uterine pressure of a woman in labor.  It comprises an elongated flexible tube which is inserted into the uterus through a curved guide tube adapted to be inserted through the vagina and cervix of a woman in labor.  The catheter tube contains a sterile liquid and is closed at both ends by a seal which is capable of transmitting pressure from the liquid within the catheter to an external liquid.  In a pre-ferred embodiment, a limp balloon is used to couple the catheter tube to a strain gauge or the like for measuring pressure.  The catheter end within the uterus includes a number of small holes and a capillary material within the tube to prevent loss of the catheter liquid.  Alternatively, and particularly where it is desired not to rupture the amniotic membrane, a second limp balloon may be used as the means for coupling between the catheter liquid and the uterus.        Where the uterine end of the catheter includes a series of small holes, the guide tube is sealed and the catheter tube is packaged with its uterine end in a sterile liquid inside the guide tube.

Abstract: ABSTRACT OF THE DISCLOSURE      A measuring cylinder has at its ends an inlet and an outlet connected in a fluid system in series with a flowmeter.  A measuring piston is adapted to travel through the measuring cylinder as a fluid barrier.  A poppet valve on the inlet side of the measuring piston is adapted to seal a passage through the measuring piston when closed so the measuring piston travels through the measuring cylinder as a fluid barrier, and to permit fluid flow through the passage when open.  A retracting piston is adapted to travel through a retracting cylinder having a smaller cross-sectional area than the measuring cylinder as a fluid barrier.  A rod is connected between the retracting cylinder and the poppet valve to open and close the poppet valve as the retracting piston moves relative to the measuring piston. The movement of the retracting piston through the retracting cylinder is controlled so as to hold the measuring piston at an upstream position of the measur-ing cylinder prior to a test run, to release the measuring piston when a test run is initiated, and to return the measuring cylinder to the upstream position after the test run.  In one embodiment, the movement of the retracting cylinder is controlled during the test run to maintain a constant difference in pressure between the upstream and downstream sides of the measuring piston.

Abstract: SIGNAL CONTROLLED INDEXING RATE SHIFTER FOR A TYPEWRITER                Abstract An indexing mechanism for a typewriter provides a signal controlled transfer to a fast paper advance rate, say for semi-automatic paper insertion, while storing the last operator-selected rate.  Two cams are employed which influence, through a follower, the engagement point of a pawl of a pawl and ratchet platen drive.  One cam is operator positionable to change the portion of its cam profile that is tracked by the follower and, attendantly, the paper advance rate.  By arranging a signal-controlled actuator to deflect the positionable cam from operative engagement with the follower, the other cam, which has a less prominent profile, is enabled to influence the pawl engagement point and provides high speed paper advance.  Upon removal of the actuator signal the positionable cam is automatically returned to its operative position i.e., the last operator selected position.
