Abstract: ABSTRACT OF THE DISCLOSURE         The braking force applied to vehicles is related to the deceleration or acceleration of each of the braked vehicle wheels, so that, for a given braking signal, the braking force is suppressed when the deceleration of the braked wheel passes a predetermined threshold (which occurs, for example, when the wheel begins to skid freely), and re-application of braking force is delayed by a time proportional to the amount of decel-eration of the wheel and of acceleration during the time it is picking up speed when the acceleration passes a predetermined threshold.  Control of the braking force is effected by a system including an element for producing a signal which is a function of the speed of each of the wheels, a differentiator device for receiving the signal and connected, through a diode which passes only deceleration signals, to a threshold device sending a control signal to a member controlling the disengagement of the brake from the corresponding wheel and operating on an all-or-nothing basis, in the case of extreme skidding, and an element permitting transmission to a memory of the signal from the diode proportional to its amplitude and duration, the signal from the differentiator device being transmitted, during acceleration of the vehicle through a diode, which passes only acceleration signals, to a device permitting the memory to dis-charge beyond a predetermined acceleration threshold.

Abstract: AUTOMATIC CORRECTION CIRCUIT FOR THE COLOR BALANCE OF A       COLOR TELEVISION SIGNAL     ABSTRACT OF THE DISCLOSURE         A correction circuit previously provided with manually entered correction signals corrects the color balance of a color television signal.  For this invention, the correction signals are automatic-ally derived by first deriving the color difference signals and the luminance signal from the corrected color television signal.           The color difference signals are then divided by the luminance sig-nals and applied to a logic circuit which furnishes a saturation control signal only when the amplitudes of these signals are in-dicative of a color saturation less than approximately 20%.  Further the luminance signal after clamping and low-pass filtering is ap-plied to comparator circuits which divide them into three bright-ness ranges.  For each brightness range a switch control signal is furnished if the saturation control signal is present which causes the first and second normalized color difference signals then pres-ent to he integrated and the so-integrated signals to be applied to corresponding inputs of the correction circuit.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to pressure responsive transducers.  The prior art transducer is an unusually compact and effective arrangement for detecting pressure variations and the two diaphragms forming the variable chambers are each soldered or otherwise hermetically secured to a respective electrode on a nonconductive sub-strate.  In the described arrangement, at least one of the diaphragms is pierced, usually along its central axis for formng a vacuum between the diaphragms.  The hole in the pierced diaphragm was then required to be soldered or sealed in a vacuum chamber.  A problem is created not only by the economics and reliability of the process, but also by the response of the diaphragm due to the distortions introduced by the opening and the seal in the diaphragm and by the differences in the reaction of one diaphragm from the other.  The present invention is directed to a pressure responsive transducer utilizing dual diaphragms on opposite sides of a sandwich of substrates formed of ceramic and having an intermediate substrate in which a slot is formed to communicate with the diaphragm chamber and eliminate the need for puncturing and/or sealing of one of the diaphragms.  External electrical connections to fixed capacitor plates deposited on the outer substrates of the sandwich are extended by forming a lead on the inter-mediate substrate which connects to the fixed plates through aligned openings in the substrates, that also communicate the chambers formed by the diaphragms.

Abstract: EASY-OPEN ECOLOGY END     ABSTRACT OF THE DISCLOSURE           An improved easy-opening end structure for use with a container includes a retained tab and a captured panel which is also retained.  The end structure includes a scoreline of an improved pinched score variety, defining a pour opening formed by fracture of the scoreline to release the panel formed by the scoreline.  Preferably, the panel is retained on the end.  The tab is affixed to the end, other than to the panel and includes an opening end positioned over the panel, but not secured thereto, and a lifting end spaced from the panel which is preferably downwardly dished and generally circular in shape.  As the lifting end is raised, the portion of the scoreline between the opening end of the tab and the attachment is popped by an upward lift of the end through essentially a class 2 lever action and thereafter the opening end bears against the panel as the tab is raised further to complete rupture of the scoreline by essentially a class 1 lever action and to push the panel downwardly and laterally through the formed opening.  The panel may be hinged or fall free into the container.  Various types of tabs as well as a method of forming a scoreline and various end structures are described.

Abstract: ABSTRACT OF THE DISCLOSURE          A displacement transducer capable of accurately measur-ing small displacements.  The transducer includes a magnetostrict-ive wire exposed to a stationary magnetic field and having an S-shape, one arc forming one section of the wire and the reverse arc the adjacent section.  One end of the wire is fixed, whereas the other end is attached to a displaceable element whereby move-ment of the element changes the radius of curvature of the arcs.          An amplifier whose input is connected to one section of the wire and whose output is connected to the other section thereof yields electrical pulses in the output to produce torsional vibration of the two sections, creating a sinusoidal electrical signal which is fed back to the amplifier input, thereby sustaining oscilla-tions therein whose frequency depends on the radius of curvature and is therefore a function of the extent of displacement.  Means are provided to linearize the relationship between displacement and frequency.
