Title: Reclosable fastener tape system  and method of employing same
Inventor: SCHATZ CLARENCE H
IPC: A61F13/56
Filed: 1979-08-23
Granted: 1982-01-19
Abstract: ABSTRACT OF THE DISCLOSURE      A reclosable fastener tape system adaptable for use in connecting together segments of a garment includes a release strip and an adhesive tape fastener. The release strip has an adhesive layer on one of its surfaces that is directly attachable to the garment, and the fastener has first and second tape sections adhered to the opposite surface of the release strip through an adhesive surface-release surface interface. The release strip and adhesive tape fastener are the only adhesive containing substrates of the tape system when the system is attached to the garment.       In accordance with a method of this invention the fastener tape system is attached to the garment, and thereafter the adhesive surface of the first tape section is attached to a segment of the garment that is different from the segment to which the second tape section is attached to thereby connect these segments together. Thereafter, if it is desired to adjust or modify the fit of the garment on the wearer, or merely open the garment to inspect it, as may be desirable when the garment is a disposable diaper, it is only necessary to detach the second tape section from the garment at the adhesive surface-release surface interface.

Abstract: CONTROLS FOR VARIABLE DISPLACEMENT MOTOR                AND MOTORS                  Abstract of the Disclosure A control for a variable displacement motor which utilizes a motor speed sensitive signal for moving the displacement of the motor toward a zero displacement setting position including a device for generating a conditioned variable signal representative of motor speed, circuitry for receiving said signal and upon the signal reaching a predetermined intermediate value applying the signal to the control device for motor displacement for causing reduction in motor displacement and with various devices in the circuit for modifying the variable signal to provide a desired relation between motor speed and motor displacement.  Utilization of such controls individually associated with plural variable displacement motors driving vehicle wheels and driven by one pump protects against spin-out of one of the wheels.  The variable motor control is usable in a load-compensated system wherein at least one motor is associated with a drive at the front of the vehicle and another motor with the drive at the rear of the vehicle and with the control circuit having a valve responsive to the pressure condition in the system pressure lines connected between the pump and motors for differing adjustment of the displacement of the front and rear drive motors.  The variable motor control is usable in a vehicle drive system with separate drives on the right and left-hand side of the vehicle to obtain steer compensation whereby the displacement of at least a pair of motors associated with the separate drives at the right and left sides of the vehicle are controlled by a circuit which includes a valve responsive to a steering signal whereby the displacement of the motors in their respective drives is varied to apply torque to the wheels in a relation to that required in connection with turning of the vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE           An automatic position control system for a slitter longitudinally slits a sheet of material into a plurality of strips.  Each slitter assembly has an upper and lower slitter station which can be moved transversely of the web to be cut and includes a main control computer.  Each positioning assemb-ly includes an electronic communication module, an electronic stepping motor drive module, and a stepping motor gear box and pinion assembly for moving the slitter assembly.  Each electronic module recognizes when the main control computer is communicating with that module by recognizing its selectable identification address.  Communication can occur in either direction between the electronic modules and the central computer.  The main control computer can command an electronic module to carry out specific functions and also can request information from the electronic module concerning its status at a particular time.  Control information can also be supplied to the central computer which can in a very rapid and orderly manner move the slitter assemblies to desired locations.  A novel communication bus structure is utilized to position the mechanical assemblies.
