Abstract: ABSTRACT OF THE DISCLOSURE          A time displacement adjustment device compensates time base errors that progressively cumulate in a time varying signal having a synchronizing information component from which the signal time base can be determined.  Periodically, the synchronizing component is sampled and a representation thereof continuously generated with the component's timing relationship to the signal retained.  Each continuously generated representation and the succeeding sample of the synchronizing component are compared to determine the time base error that progressively occurs in the signal between the successive samples of the synchronizing component.  That signal is expanded or compressed accordingly to correct the erroneous timing.

Abstract: TUBE CUTTING APPARATUS                     ABSTRACT OF THE DISCLOSURE              A device for cutting lengths of tubing from a longer tube utilizes an external pair of cutting dies and an internal pair of punches.  An eccentric relative motion ("shimmy") of the cutting dies results in the desired cutting of the tube.           The punches are inserted into the tube from the end of the tube from which the length of tubing is to be cut.  A restraining arrangement prevents the punches from moving farther along the tube than is desired, while a punch positioning mechanism pre-vents movement of the punches toward the open end of the tube.           Thus, the internal punches are accurately positioned with respect to the external cutting dies.  A centering arrangement is utilized to insure  of the punches.  After the cutting dies have been actuated to cut the tube, the tube is advanced an amount corresponding to the length of tubing to be cut, after which the punch positioning mechanism is reciprocally withdrawn to permit the cut length of tubing to be discharged and then reinserted to position the punches for the next cutting opera-tion.  During the cutting operation the punches are held in the desired position between the punch positioning mechanism and the restraining arrangement.  Various types of restraining means may be utilized to hold the punches, and the resistance of the restraining means to further movement along the tube may be adjusted to any desired level.

Abstract: AN IMPROVED PROCESS FOR THE PRODUCTION OF       SOLUBLE HIGH MOLECULAR WEIGHT POLYURETHANES WHICH ARE FREE FROM ISOCYANATE GROUPS                Abstract of the Invention This invention relates to an improved process for the production of high molecular weight polyurethanes which are free from isocyanate groups and are soluble in organic solvent in reduced reaction times.  The reactants, polyol and isocyanate, for example, are mixed together with solvent and the temperature is permitted to rise under the effect of the heat of reaction.  The reaction mixture is then cooled with solvent addition in such a way that the viscosity of the reaction mixture remains constant until the optimum     temperature for the polyurethane formation reaction ("specific reaction temperature") is reached.  The mixture is then gradually cooled until there is no residual isocyanate present and the polymer is recovered from the reaction mixture.

Abstract: PELLET CRUSHING STRENGTH TESTER               Abstract of the Disclosure An apparatus and a method is disclosed for deter-mining the crushing strength of pellets of a powdered mater-ial by compressing individual pellets between one pellet-contacting face on a force-exerting means and another pellet-contacting face on a force-measuring transducer.  The trans-ducer provides an output current at a voltage which varies in correspondence to the compressive force that is applied to a pellet during the crushing thereof.  Accordingly, a pellet is first placed between the aforesaid pellet-contacting faces and the force exerting means is then driven toward the transducer at a controlled rate for compression and crushing of the pellet.  Current voltage from the transducer is recorded permanently on a chart or else temporarily by means of a peak voltage remembering module in conjunction with a voltmeter having a digital read-out.

Abstract: ABSTRACT OF THE DISCLOSURE         A multipole circuit breaker including a trip release actuator having a single coil coaxially surrounding a plunger and mounted within a hollow cylindrical actuator support frame.  The actuator is mounted in association with a latch mechanism and includes a spring biasing the plunger toward release of the latch mechanism.  The coil is respon-sive to an electronic sensing and control circuit and serves, when energized, to oppose the action of the bias spring and maintain the plunger in a position to prevent release of the latch mechanism during normal conditions.  Upon either undervoltage or overcurrent conditions the sensing and control circuit deenergizes the coil, allowing the bias spring to move the plunger into engagement with the latch mechanism, effecting release of the latch mechanism and separation of the circuit breaker contacts.
