Abstract: ABSTRACT    Disclosed is an apparatus for completely filling a silo from a central point at the top of the silo.  Silage is dropped from a centered discharge opening in a fill tube extending from the upper margin of the silo sidewall.  The fill tube is articulated inter-mediate its length and the innermost portion is swung sidewardly when the apex of the deposited silage reaches the discharge open-ing.  A spreader plate is then positioned in cooperative relation with the open end of the stationary outermost portion of the fill pipe and directs the final volume of silage (necessary to fill the silo) toward the far wall area of the silo.  A locking member carried by the spreader plate assures that the two sections of the fill pipe are held in longitudinal axial alignment.

Abstract: AUTOMATIC COPIER MODE CONTROLS                          ABSTRACT A multi-mode document reproduction machine (copier) includes automatic reselections to a dominant copy mode.  A dominant mode is that machine code used in the most number of copy jobs, irrespective of the number of copies made in any of the modes.  A machine having complex operational modes, such as multi-copy run jobs, automatic reselections require predetermined condition precedents indicating given copy job status.  In certain error recovery functions, machine reselections supersede error received status states.

Abstract: Abstract of the Disclosure A high pressure pump comprising a valve body having a first housing secured at one of its ends to one end of the valve body and having a body member secured to the other end thereof. A second housing is secured to the body member with a piston rod movably extending through the body mem-ber and the first and second housings. A first piston is secured to the piston rod and is movably positioned in the first housing to define first and second chambers. A second piston is secured to the piston rod and is movably posi-tioned in the second housing to define third and fourth charmers. A first check valve means is in communication with the third chamber and the source of fluid to be pumped with a second check valve means being in communication with the fourth chamber and a source of fluid to be pumped. The valve body has a pilot valve bore formed therein which movably receives a pilot valve means. The pilot valve means is connected to the piston rod so that the pilot valve means will be moved from a first position to a second position when the piston rod moves from a first position to a second position and so that the pilot valve means will be moved to its first position when the piston rod moves to its first position.  The valve body also has a main valve bore formed therein which movably receives a main valve means.  A hydraulic pump is in communication with the main valve means and the pilot valve means for supplying hydraulic fluid thereto.  A first passageway means fluidly connects the main valve means and the first chamber with a second passageway means fluidly connecting the main valve means and the second chamber.  The main valve means and the pilot valve means are fluidly connected so that hydraulic fluid under pressure will be supplied to the first chamber, when the main valve means and the pilot valve means are in their first positions, to cause the first and second pistons to move from their first positions towards their second positions so that the second check valve means will permit the passage of fluid therethrough.  The piston rod moves the pilot valve means to its second position when the piston rod reaches its second position so that hydraulic fluid under pressure is supplied to the main valve means to move the main valve means to its second position so that hydraulic fluid under pressure is supplied to the second chamber to cause the first piston means to move towards its first position so that the first check valve means will permit the passage of fluid thereby.

Abstract: ABSTRACT OF THE DISCLOSURE full rotational freedom, substantially zero friction electrical contact assembly for conducting electrical currents between relatively rotatable members of sensitive instruments such as gyroscopic devices and the like and a method of and apparatus for the assembly thereof is disclosed.          Each electrical transfer unit of the assembly comprises a pair of coaxial, concentric, coplanar, continuous, concave conductor rings, one mounted on a relatively fixed member and the other mounted on the rotatable member, the relative diameters of the rings providing a substantial annular radial gap therebetween.  A resilient, electrically conducting, continuous, filamentary loop is disposed in the radial gap such that its generally flat outside surface contacts and rolls on the concave surfaces of the concentric conductor rings.       The loop/conductor interface provides self-capturing and retaining forces to accommodate any misalignment between the rings and movements of the loop within the radial gap in a vibratory and/or shock environment all without producing frictional torques on the rotatable member.  The critical dimensional parameters of the concave conductor ring surface and the loop, particularly its free (unassembled) diameter relative to the radial distance between the concentric conductors, its thickness and width, and its material characteristics are selected so as to provide: substantially zero friction and coupling torque on the rotatable member; maximum retention capability; maximum current conduction; and maximum life.  In another aspect of the invention, the assembly is designed such that the loops may be readily assembled without deforming, overstressing or damaging the same while permitting loops of various acceptable free diameters and hence preloads to be employed, and furthermore, the design of the assembly allows the selection of ring concavities of various depths to satisfy the vibratory and shock environment of various applications.

Abstract: 26260 I/O TERMINAL IDENTIFICATION Abstract of the Disclosure Control of the data format programmed into an interface means by a computer means is provided in response to the data format required by an I/O device. A register in the interface means is programmed to respond to only a first digital address from the computer means. A switching means having first and second positions is utilized to create "don't care" positions in a digital address from the computer means to the interface means. Because of the "don't care" positions in the digital address the register in the interface means will respond to a second digital address when the switching means is in the first position. The register will not respond to the second digital address when the switching means is in the second position. When the register responds to the second digital address then the computer programs the data format required by a first I/O means into the interface means. When the register does not respond to the second digital address then the computer programs the data format required by a second I/O means into the interface means. Thus, the position of the switching means determines the data format which will be programmed into the interface means.
