Abstract: ABSTRACT OF THE DISCLOSURE:              A roll of the type which is used in a paper machi-ne has an inner roll body covered with a plurality of strips.          The strips include pairs of strip portions situated one next to the other along the roll body and covering the  outer surface thereof.  Each pair of strip portions extends through 360° around the roll body with each pair of strip portions including one strip portion at least part of which circumferentially surrounds and overlaps at least part of the other of each pair of strip portions.          This  one of each of strip portions circumferentially presses ra-dially inwardly against at least said part of the other of each pair of strip portions to press the other of each pair of strip portions against the outer surface of the roll body.  The one of each pair of strip portions has a coefficient of thermal ex-pansion greater than the other of each pair of strip portions and when initially placed on the roll body is in a heated condi-tion at a temperature sufficiently high so that upon cooling the one of each pair of strip portions will contract against the other of each pair of strip portions to provide the circumferential inwardly directed radial pressure acting to press the other of each pair of strip portions against the outer surface of the inner roll body.

Abstract: APPARATUS FOR CONDUCTING SECONDARY    TESTS FOR SECURITY VALIDATION                    ABSTRACT OF THE DISCLOSURE               Apparatus for conducting secondary tests for security validation are presented.  In one embodiment of the invention a light source, either infrared or visible, is cast upon two neighboring areas of a paper purported to be a valid instrument, these areas being of different light reflective characteristics.  Photocells are maintained in close juxtaposition to each of these two areas and the light reflected therefrom or passed therethrough is sensed by the photocells.  Comparator circuits are interconnected with the photocells and, in part, determine the validity of the instrument on the basis of the comparison of the intensity of light reflected by each of the two areas.  In one embodi-ment of the invention, a reference reflective surface is provided in juxtaposition to one of the photocells to test those instruments not having neighboring areas of different light reflective characteristics.  In yet another embodiment of the invention, a reference photocell is provided for sensing the light actually emitted from the light source and establishing this light emission level as a reference level.  Further, dividers and comparator circuits intercon-nect this reference photocell with one of the other two photocells for further determining the instrument's validity by testing whether the light reflected from one of the areas falls within a predetermined percentage of the light actually emitted from the light source.  The entire unit of the light source, photocells, and reference photocell are all maintained within a singular molded housing preferably constructed of a highly light reflective material.

Abstract: ABSTRACT           A miniaturized balloon catheter assembly includes a cannula and an inflatable tubular balloon constructed of a silastic tubing detachably mounted on the cannula for performing a surgical procedure in an animal vessel, especially a human vessel in response to pressure therein.  In one embodiment, the balloon is detachably mounted with the detachability being responsive to pressure.  In another embodiment, a valve, such as a pin-hole in the silastic material for example, is included in the balloon which opens only after the pressure within the balloon exceeds a pre-determined amount.      According to a method of the invention, the cannula and the attached balloon are inserted into a small vessel and the balloon is pressurized therethrough.  The balloon is partially inflated to allow fluid flow in the vessel to position the balloon at a desired location.  Pressure is thereafter increased in the balloon to activate a desired procedure within the vessel.  In the first embodiment the desired procedure is to withdraw the cannulla from the affixed balloon as the increased pressure lubricates the connection between the balloon and the cannula.  In the second embodiment, the desired procedure is for the increased pressure to open the pin-hole and disperse a fluid into the vessel from the balloon.

Abstract: Abstract of the Disclosure A system which is capable of allowing an attending physician to continuously monitor the electrocardiogram (ECG) signals produced by a cardiac patient. The signals, generated by the patient, are first recorded in real time over a predetermined time period established by the physician. At the conclusion of the predetermined time period a monitoring station is automatically alerted by telephone and commences receiving the patient's real time ECG signals directly. The recorded ECG signals are then transmitted in a compressed time fashion to the monitoring station simultaneously with the real time ECG signals. The monitoring station receives the compressed time and the real time transmitted signals and following analysis thereof transmits a report of selected portions of the ECG to the physician. Upon instructions from the physician, the monitoring station either returns the recording apparatus to its normal operational status for a predetermined time period, or continues to receive and analyze the real time ECG signal until the patient's signal is sufficiently stable and then returns the recording apparatus to its normal operational status. This process repeats continuously. The physician communicates directly with the monitoring station and with the patient as may be required.         The system and method provides close and complete monitoring of the patient with complete ECG, data retrieval and individual-ized close patient surveillance.
