Abstract: Abstract of the Disclosure RADIAL-PLY PNEUMATIC TIRE WITH REVERSE-CURVATURE                     CARCASS PLY     A radial-ply pneumatic tire (200,400) has a carcass (220,420) that has a reverse curvature, that is, an outwardly concave shape, centered about the tire's equatorial plane (EP).  A wedge (260,460) of elastomeric material is positioned above or below the belt structure (230,430) of the tire.  If positioned above the belt structure, the wedge is used with a carcass cord angle in the range from 65° to 80°.  This carcass structure also may be used when the wedge is positioned between the belt structure and carcass.  The tire has an aspect ratio less than 75%, but an aspect ratio in the range from 40% to 65% is preferred.  The wedge has a shape on its radially inner side that is similar to a low-amplitude cosine function. Particularly when the wedge is above the belt structure (providing both it and the belt structure with a reverse curvature), the belt cord angle is less than a "critical angle" of about 25°.    The invention, when practiced in its preferred form, provides a belted tire which has "natural shape" in its sidewall regions for whatever "radial" cord angle is selected for the carcass ply or plies. However, the tire also has "natural shape" in the portion of the radial carcass underlying the belt structure, but the "natural shape" is for a cord angle substantially equivalent to that or those low angles used in the belt structure.  This low-angle "natural shape" for a bias-ply carcass is predicted by the equations of John F. Purdy in "Mathematics Underlying the Design of a Tire" to include a reverse curvature in the crown area of the bias-ply carcass.

Granted: 1992-07-07
Abstract: TIME DIVISION MULTIPLEX ARRANGEMENT Abstract Modems, data service units, application modules and other data communication devices, installed in a common equipment cabinet, are interconnected by way of a time division multiplexed bus. Time slots assigned to the various devices recur at a number of regularly-spaced access periods across each time division multiplex frame. The rate at which the access periods occur and the total number of access periods that make up each frame are chosen in such a way as to accomodate a mix of devices having respective bus access rates wherein there is at least one pair of rates for which neither rate of the pair is a whole number multiple of the other. The process of allocating access periods to the time slots is carried out using a known lemma to identify linear Diophantine equation solutions.

Abstract: ABSTRACT OF THE DISCLOSURE        A sheet tension measuring device is disclosed for measuring the tension of a moving sheet wherein a moving sheet is accurately positioned with pinchers at 2 spaced locations.  The sheet is deflected between these pinchers from its nominal straight line path, and the amount of deflection and deflecting force are measured. The pinchers iron out any wrinkles in the sheet as the moving sheet slides through the pinchers.  Sheet tension is computed based upon the measured deflection force and deflection distance.  The resulting measurements of local sheet tension are used to correct nondestructive sheet strength measurements.  A device and method are also disclosed for nondestructively determining the sheet strength and the extensional stiffness of the sheet in the machine direction and in the cross-direction.

Abstract: PHA.40539                                         6-5-1989 ABSTRACT: Method and apparatus for the recording and replay of interlaced signals.     Upon receipt of an interlaced television signal, the field generator generates a first selector signal arbitrarily selecting one of the fields as top field and a second field selector signal selecting the other as bottom field. The received television signal is entered into memory under control of the field selector signals. A regenerated vertical synchronization signal is furnished for the first horizontal synchronization signal following vertical synchronization in top field. This regenerated vertical synchronization signal resets a counter which counts horizontal synchronization signals repetitively to a count of five. A second regenerated vertical synchronization signal is furnished when the count of five is reached following the vertical synchronization signal of bottom field. The counter is reset by each first regenerated vertical synchronization signal. (Fig. 4)
