Abstract: A binary encoded signal which is to be clamped at a desired binary value is simultaneously applied to a digital subtractor and a digital adder. The digital subtractor subtracts the difference between the desired binary value and the value of the binary encoded signal. The resulting difference is applied to a storage flip-flop circuit having a switching pulse input which receives a periodic signal. The flip-flop transfers the last received difference until the periodic signal is received causing it to transfer the latest received difference. A binary adder adds the output of the storage flip-flop to the binary encoded signal. This results in a corrected clamped binary encoded signal.

Abstract: Aircraft flaps provide rearwardly convergent channels which terminate at or near the trailing edges of the flaps. The forward intakes of the channels are closed when the flaps are elevated and open when the flaps are depressed. A control is programmed to operate the flaps so as to maintain minimum drag until sufficient ground speed is attained for take-off, and to limit the velocity of air discharged from the channels to sub-sonic speeds.

Abstract: A structural laminate comprises at least one planar facing sheet with a rigid foam attached to one surface of the facing sheet. The rigid foam is characterized in that the major recurring chemical linkage therein is the isocyanurate moiety. Distributed substantially evenly throughout the foam is a mat of long straight glass fibers arranged in layers substantially parallel to the facing sheet. The process for producing this structural laminate comprises the steps of contacting a thin, substantially incompressible yet expansible mat of long straight glass fibers with a foam-forming mixture of an organic polyisocyanate and a diol, positioning a facing sheet on each face of the mat, and passing the facing sheets having the mat and the foam-forming mixture there between through the nip of two rotating rolls.

Abstract: An indexing device consists of a base, a lid pivoted to the base, and a plurality of cards pivotally mounted between the lid and the base for selective movement with the lid. Each card has a lug at a front edge thereof, the plurality of cards being arranged such that the lugs are serially positioned at specific intervals in step-wise fashion. A like plurality of levers are pivoted to the base at corresponding specific intervals. A first end of each lever has a push-button fixed thereto for downward digital manipulation. The opposite end of each lever extends under the front edge of the cards for upward movement to select a desired number of cards to pivot upward with the opening of the lid.

Abstract: The present invention relates to a method of determining the "P" and "S" wave propagation velocities and the Young's modulus and Poisson's ratio in geological formations. An acoustic transmitter is placed in a borehole, and receivers in another borehole at predetermined heights. The differences in the propagation times of "P" waves and the exact distance between receivers and transmitter enable the velocities of the "P" and "S" waves to be obtained with sufficient accuracy to calculate the constants. The invention is useful in civil engineering.
