Abstract: APPLICATION OF:  Kenneth K. Knapp and Charles R. Cornell FOR:  A CONTROL FOR A VARIABLE       DISPLACEMENT PUMP OR MOTOR                          A B S T R A C T         A control including a control valve and an override valve for use with a variable displacement pump or motor unit having a pair of strokers into and out of which fluid must be directed to vary the displacement of the unit.  The control valve ports fluid from a high pressure source to a first control pas-sage and from a second control passage to a low pressure source, reverses said flow, and terminates said flow.  The override valve is interposed between the control passages and the strokers and defines a pair of override passages therein used to direct fluid from one control passage to one stroker and from the other stroker to the other control passage.  The override valve is selectively movable between a first position directing such flow therethrough and a second position in which such flow is terminated between the control passages and the strokers.  Upon flow termination, the override valve communicates, via a bore in the override valve, the strokers with one another to allow the pump unit to go to minimum displacement  or the motor unit to go to maximum displace-ment.  In the preferred embodiment, the override valve is respon-sive to the high pressure fluid being ported from or to, respec-tively, the pump or motor unit.  The control may also include a centering valve interposed between the control valve and the override valve.  The centering valve is responsive to the pressure of the control fluid to define passages between the first and second control passages and the first and second override passages.          Upon a loss of control fluid pressure, the centering valve moves -i-to a second position to cross port the control valve passages and the override valve passages.  The override valve may also be actuated via external signals such as an electrical, mechanical, or manual input.                             -ii-

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for determining the precise location of faults in a pipeline, e.g. for use after a travelling pig has indicated the area of a pipeline containing a fault, comprises rail structures, the ends of which are received in end pieces.          The end pieces receive releasable buckled straps, by means of which the apparatus may be releasably secured to a pipeline.          A detector mounting means is movable along the rails, and carries a detector such as a gaussmeter, in a slot extending across the detector mounting means.  The bottom surface of the detector mounting means receives the sensor at a constant spacing from the pipe surface, so that the detector can be moved across the pipe surface, by moving the detector assembly along the rail structures and by moving the detector along the detector mounting means, to determine the location of surface imperfections.

Abstract: ABSTRACT         In a field access type bubble memory system using a major loop minor loop organization, additional redundant minor loops are included in each memory device so that defective minor loops may be disregarded and the memory retain its nominal capacity.  Thus, the total number of minor loops is in excess of the nominal capacity.  A stationary register is formed integrally with the major loop by coupling bubble idlers directly to the major loop bubble propagation path.  The stationary register has as many register positions as the total number of minor loops coupled to the major loop.  An appropriate binary code identifies in the appropriate register location the corresponding minor loop which is defective, includ-ing nominally defective minor loops, if necessary, so that a number of minor loops equal to the nominal capacity of the memory are identified as good.  Each time the memory is accessed, the contents of the stationary register are accessed, nondestructively, and read into and combined with the contents of the major loop on an every other one basis.  Appropriate logic identifies which minor loop is to receive data and those minor loops from which data can be read.  A single conductor can be used to control access from both the stationary register and the minor loops to the major loop or separate conductors may be used for the stationary register and the minor loops.
