Abstract: CENTRAL PROGRAMMABLE CONTROLLER      WITH FAULT PROCESSOR              Abstract of the Disclosure A programmable controller includes four remotely located input/output interface racks which are connected by cables to an I/O scanner circuit which is centrally located with the controller processor and memory.  Input and output data is serially transmitted between the I/O scanner circuit and the interface racks, and fault processors are located therein to monitor the operation.  The fault processors include fault tolerant detector circuits which ignore erroneous transmissions caused by industrial noise, but which initiate a shutdown process when malfunctions occur.          The shutdown process is controlled by a programmable disab-ling circuit which is responsive to program instructions stored in the controller memory to allow independent, quasi-independent, or dependent operation of the machines con-nected to each of the four interface racks.

Title: Weld inspection system with dual flaw detection
Inventor: HENRY EDWIN B JR
IPC: G01N29/26
Filed: 1977-01-31
Granted: 1981-02-17
Abstract: A weld inspection system uses fluoroscopic flaw detection particularly sensitive to volumetric type weld flaws and ultrasonic flaw detection particularly sensitive to planar type weld flaws.  Both inspections are performed simultaneously throughout the pipe length.  Each system marks the pipe with a distinguishing mark to identify the location of the flaw detected by that system.  The fluoroscopic system is a high resolution system, the ultrasonic system avoids detection of minor nonrejectable variation in weld bead geometry and is calibrated to a desired sensitivity level.

Abstract: ABSTRACT OF THE DISCLOSURE            In conveying systems with a continuous chain to transport load problems have arisen over the space required for turnover rollers to effect changes of direction, the difficulty of accomplishing non-planar changes of direction and the cost of turnover rollers. This system provides a tubular guide which enables three dimensional direction changes at any selected locations to be made to a load guided by and running along the tubular guide. The chain driven by a toothed drive wheel is guided through a tubular guide by spherical sliders on the chain and a connecting piece on the chain projects through an elongate slit extending along the tubular guide to traverse the system on operation of the drive wheel which has indentations engaging the sliders to transport the chain. Instead of sliders the cable may be guided by internal guide discs in the tubular guide.

Abstract: ABSTRACT OF THE DISCLOSURE         A projector for motion picture film includes a servo motor which is controlled to advance film frame by frame to a projection station.  A capstan on each side of the projection station is controlled to maintain film loops of substantially constant size and an associated reel motor delivers film to and takes film from each capstan.  Each associated capstan and reel motor are controlled so as to maintain substantially constant tension on the film.  A film guide defines the projection station and also includes provision for masking peripheral areas of each frame.  Each capstan and an associated pinch roller are designed so as to eliminate creeping of film from between the two.  A circuit for controlling the reel motors is arranged to permit fast winding of film directly from one reel to the other with an automatic braking feature.

Abstract: DAMPING VIBRATIONS IN VOICE COIL ACTUATOR      Abstract of the Disclosure An actuator for a disk file comprises a carriage/arm assembly secured to a coil and movable longitudinally upon energization of said coil.  To minimize the amplitude of longitudinal resonance vibration in the actuator upon energiza-tion of the coil, the coil is secured to the outer of two concentric overlapping members and the carriage is secured to the inner member.  Elastomeric material is disposed radially between and adhered to said concentric members to act as a combination damping means and primary stiffening means for transmitting the major proportion of shear force between said members, and hence, between said coil and carriage.      Because stiffness of the elastomeric material varies significantly over the temperature range over which the disk file operates, auxiliary stiffening means is desirably included, preferably in the form of beams which act as springs restraining longitudinal motion between the outer member (and hence the coil) and the carriage.  These beams are formed by providing a series of arcuate slots equally spaced circumferentially adjacent that end of the outer member remote from the coil.  Each beam is thus defined by that arcuate segment of the outer ring which is between said remote end and the slot.   This remaining portion of the shear force is transmitted via the beams which are nested in notches in the carriage.
