Abstract: Abstract A modular center filler and center plate may be constructed as a unit away from the car and adapted for con-nection to the center sill webs of a railway vehicle. The center filler has a thick bottom plate which extends beneath the center sill and has pairs of interconnected longitudinal and transverse sill reinforcing plates arranged in a double I-beam manner.  The center plate has longitudinally extending attached skirts, and bevels are provided which allow the car to rock at the bevel lines.  Forces transmitted through the center plate at the bevels are absorbed and distributed by the associated longitudinal plates and other bolster and center filler structural elements.

Abstract: ABSTRACT         A linear induction drive system for an accelerating and decelerating moving walkway comprising a plurality of interconnected platforms that encompass the entire path of travel of the walkway and overlap one another by a small portion of their length in linear constant speed zones and by a substantial portion of their length in acceleration and deceleration zones is disclosed.  The linear induction drive system comprises a plurality of stationary linear induc-tion motor stators located in the constant speed zones. Affixed to the platforms are reaction rails formed of a plurality of links rotatably attached to one another such that the links are linearly aligned with one another in the constant speed zones and fold in an accordian manner in the acceleration and deceleration zones.  In the constant speed zone the reaction rails are driven by power applied to the linear induction motor stators.  Due to the platform inter-connection this drive force moves the entire walkway.  The links fold in a plane parallel to the plane of motion of the platforms.  Preferably, a pair of links are associated with each platform--one link rotatably attached to each platform and the other links rotatably connecting the platform links together.  Each link is flat and elongate, and comprises at least tow laminations.  One lamination is formed of an electrical conducting nonmagnetic material, such as aluminum or copper.  The other lamination is formed of a magnetic material, such as iron.

Abstract: COMPENSATION OF SENSOR VOLTAGE FOR  REFERENCE POTENTIAL VARIATION              ABSTRACT OF THE DISCLOSURE        An improved electrical system particularly suit-able for use in a motor vehicle.  The improvement provides compensation of a signal used in association with an electronic circuit.  Such compensation is made necessary because of variation in the potential that occurs at a source of electrical energy in the system relative to the sensor reference potential.  The variation in potential results from currents flowing through a conductor interconnecting the sensor and the energy source, which current may be of varying character due to the operation of other devices associated with the system.  Compensation is achieved with a differential amplifier coupled both to the energy source and to the sensor.

Abstract: LUMBER INSPECTION AND OPTIMIZATION SYSTEM            ABSTRACT A  lumber  inspection  and  optimization  system  is disclosed combining the speed of electro-optic scanning for flaw detection with electronic data manipulation and computation for optimizing the utilization of the lumber in accordance with an order entry list specifying the dimensions, grade and priority of products desired to be cut from each board inspected by the system.  The system receives  input data from an order entry device and an electro-optical  scanner.    Digital  scan data  from  the electro-optical  scanner  is  electronically processed  to form a flaw data buffer containing the edge location of all  the  detected flaws  enlarged  to  compensate  for defective  material   usually   surrounding   each   flaw. Optimization   of   the   material   is   accomplished   by electronically comparing the order entry data with the location of the flaws in the flaw buffer to generate cut line data indicative of where the board is to be cut.  The cut line data may be used ts either actuate a saw to cut the lumber at the locations specified by the cut line data or actuate a marker to mark the lumber at the specified locations.  When the order entry list includes products having permitted deects, the disclosed system includes a defect  classification  input  device  permitting  a  human inspector to insert defect classification data into the flaw data buffer prior to optimization.   The preferred embodiment utilizes a mini computer programmed to process the  flaw data,  optimize  the utilization of  the board inspected and generate the cut line data.
