Abstract: ABSTRACT OF THE DISCLOSURE           A method of and apparatus for recording a video signal in successive parallel tracks on a record medium, and for repro-ducing the recorded signal.  The video signal. which may be the luminance component of a composite color television signal, fre-quency modulates a carrier to produce a frequency modulated video signal.  The phase of the frequency modulated video signal is selectively shifted in selected line intervals and is recorded in parallel tracks such that the phase difference between fre-quency modulated video signals in at least some adjacently re-corded line intervals of successive tracks is an odd multiple of .pi..  In one embodiment, the difference between the phase of alternate line intervals which are recorded in one track and the phase of alternate line intervals which are recorded in the next adjacent track is equal to an odd multiple of .pi..  In accordance with another embodiment, the difference between the phases of successive line intervals which are recorded in the same track is equal to an odd multiple of .pi..  During reproducing, the successive tracks are scanned the frequency modulated signals recorded therein are reproduced together with a crosstalk compo-nent which is picked up by the transducer from an adjacent track, the crosstalk components being out of phase with each other.          The reproduced frequency modulated signal is demodulated so as to recover the original video signal and an additional component, the latter being due to the phase shifting of the frequency modu-lated signal.  The additional component then is eliminated from the recovered video signal.

Abstract: ABSTRACT OF THE DISCLOSURE     A digital control device wherein both an input drive, which, in response to signal pulses, produces a specific increment rotation of an output drive, and a feedback drive, which is driven in proportion to the incremental rotation so produced, are connected to drive a differential gear device, the output of which drives a pair of multi-stage, intermittent drive counting devices, one in a forward direction, the other in reverse.   Movement of the last stages of such devices are conditioned to activate said output drive and they are set in null positions wherein a very few advancing increments of movement of the first stage will generate incremental movement of all subsequent stages.   When the input drive starts, the last stage of only the advancing counter will advance and activate the output drive in a direction to oppose the input.          Return of the counters to null positions will deactivate the output drive.

Abstract: IN MARINE SEISMIC EXPLORATION WITH LONG  SOURCE AND DETECTOR ARRAYS     Abstract of the Disclosure In marine seismic exploration, a long array of sources efficiently transfers energy along the reflection path.  Multiple reflection rejection is achieved by normal move-out discrimination at selected trace distances for each reflection.  The length of the source array is changed in accordanc, with the geological characteristics of the sub-surface formations being explored and the reflection time of reflections from formations of interest.  A split source array allows one section of the array to be moved with respect to the other to change the overall length of the array without changing the number of sources which are fired.  Primary to multiple reflection enhancement is obtained by selecting only traces having source to detector offset distances with a primary to multiple amplitude response ratio greater than one.

Abstract: ABSTRACT OF THE DISCLOSURE    A rocker arm and a method of making the same are provided. In one form, the rocker arm is of the wrap-around type in which a metal sheet is appropriately symmetrically shaped and is  then bent back on itself on the line of symmetry at which one end of the rocker are body is formed.  The two halves are then affixed togather by projection welding or the like. The rocker arm has two diverging, downwardly-extending walls formed at the one end of the body with a separate socket member the resistance welded to the walls.  The socket member has a central oil opening which supplies oil to a push rod from an oil passage in the rocker arm body.  This passage, in turn, communicates with an oil supply passage in a shaft on which the rocker arm is rotatably supported through a hole in a bearing sleeve carried by the rocker arm body. A second, separate passage communicates with the other end of the rocker arm and with the oil supply passage in the shaft through a separate hole in the bearing sleeve.  In another form, the rocker arm is made from two separate halves which are again affixed together by projection welding or the like.  In this instance, the socket is integrally formed in the two halves by coining.  In a third form, the rocker arm is made by the wrap-around technique with the socket being integrally formed in the two halves by coining.  This combination enables the socket to be continuous and seamless around the outer end portion.
