Abstract: ABSTRACT OF THE DISCLOSURE          A wire stripper tool having a pair of arms connected at a pivot intermediate the ends thereof, one arm having an anvil at one end and the other arm having an opposed cutting head which supports a blade at the front of the head for slitting the wire insulation longitudinally, and a blade at each side of the head for slitting the insulation circumferentially.          The anvil has a seat extending normal to the second-named blades for positioning the wire while being slit.          A spring is located between the pivot and the cutting blades and normally biasing the cutting head to a closed position relative to the anvil.  The arms have opposed inner surfaces which are divergent rearward of the pivot to enable the arms to be squeezed together rearward of the pivot thereby to move the cutting head to an open position relative to the anvil which allows a wire to be positioned in the seat for slitting.  The inner surface of one arm is slotted and the inner surface of the arm opposed thereto has a guide rib with one end disposed in the slot in both the open and closed position of the cutting head.  With the construction of the disclosed wire stripper, there is reduced the likelihood of incomplete or irregular slits due to the spring coil being used as a pivot, due to the inability to achieve acceptable parallelism with a pair of guide flanges and due to the form of the spring in the known tool.

Abstract: ABSTRACT      Method and apparatus are disclosed for the serial transfer of data in a clockless manner.  Data is transmitted in the form of signal state changes from a dispatcher to a receptor.  The receptor is operative to translate the signal state changes into data and thereafter signal the data dispatcher that it has done so.  The dispatcher is operative to transmit the next piece of data only after it has been appropriately signalled by the receptor.    In accordance with another aspect of the invention, the dispatcher is capable of notifying the receptor when an end to the transmittal of data has occurred.  The data receptor does not signal the dispatcher for further data when this occurs.  The receptor instead signals a data sink that the previously transmitted data is available for copying.  The data sink copies the data and thereafter authorizes the receptor to initiate further data receiving operations.

Abstract: METHOD AND DEVICE FOR AUTOMATICALLY DIRECTING       SYSTEMS TO THE CENTER OF WELD GAPS, WELD JOINTS                     AND WELD CHAMBERS        ABSTRACT OF THE DISCLOSURE        An arrangement for automatically tracking systems to the center of weld gaps, weld joints or weld reinforce-ments, in which a scanning probe is used for receiving signals reflected by a workpiece surface, as long as the surface is substantially parallel to an acting surface of the probe.  The signals break down spontaneously when the surface clearly deviates from the parallel as in the case with left and right flanks of gaps, joints or rein-forcements.  The signal breakdown is a decrease in intensity of a reflection signal to a fraction of previous reflection energy.  The breakdown of the signal is applied for storing an electrical value corresponding to the instantaneous probe position.  The center of the gap, of the joint or of the reinforcement is computed from the stored electronic position values, and the computed value is compared with an electrical value corresponding to the center position of the system.  A control command signal is formed from a difference of compared values for actuating a drive unit to return the system to the computed center of the weld gap.  The signals are evaluated only up to their first re-flection breakdown per probe oscillation direction.

Abstract: HEAT PUMP                ABSTRACT OF THE DISCLOSURE          Heat pump apparatus employing a continuous loop passageway containing a plurality of freely movable, unrestrained bodies.  The bodies are accelerated around the passageway in one direction by adiabatic expansion of a fluid between the bodies in an expander region of the passageway.          The expanded, cooler fluid is discharged from the passageway via one or more vent-intake ports in the passageway beyond the expander region.  Warmer fluid enters the passageway via said ports and is compressed between the propelled bodies in a compression region of the passageway, thereby raising its temperature from a first temperature (e.g., the temperature of the outdoor atmosphere or an industrial waste heat stream) to a second temperature higher than the first.  The compressed, warmer fluid is thereafter passed through a heat exchanger to extract heat.  In passing through the compression region the bodies are decelerated and they then pass through a thruster region of the passageway wherein a force is applied to the bodies to counterbalance the external forces acting against the bodies as they move around the loop passageway.          From the thruster region the bodies pass to the expander region to repeat the cycle.  From the heat exchanger the fluid, typically together with additional compressed fluid from an external source, is introduced into the expander region to again accelerate the bodies.
