Abstract: ABSTRACT     When sheets of glass or other deformable material are shaped by a method that comprises the use of a vacuum holder having a lower sheet wall provided with an array of apertures through which air is drawn by vacuum to engage a sheet to be shaped by vacuum, the array must be larger than each dimension of the sheet to be shaped so that when the sheet arrives at a shaping station in proper alignment for engagement by the vacuum holder, there is a continuous line of apertures beyond each side of the sheet to be engaged by suction.  Otherwise, when the sheet is engaged by suction, it is displaced an uncontrolled amount transversely and/or longitudinally en route to engagement by the apertured lower wall.  Since the amount of displacement cannot be controlled under such circumstances, the sheet becomes misaligned relative to its desired position of engagement against the vacuum holder.  By providing apertures at approximately equal distances around the periphery of the sheet, this tendency for displacement is minimized.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for eliminating the disturbances related to fluctuations of the load in chopped power supplies.  A magnetic circuit with a primary inductance (Lp) is coupled to a secondary inductance (Ls).  The value of the secondary inductance (Ls) is automatically adapted as a function of the voltage (Us) at the terminals of the load (X).  This ensures total transfer of the magnetic energy for each period of the chopping frequency.  Complete demagnetisation of the circuit is obtained at each period of the chopping frequency.  This eliminates certain disad-vantages in the prior art notably saturation of the circuit material which, in the prior art, results in incapacity to translate linear flux variation, causing a large increase in current in the chopping equipment, usually transistors, and thus the possibility of damage.

Abstract: SMALL LOG BUCKING SYSTEM            ABSTRACT OF THE DISCLOSURE         A bucking station for small logs is disclosed, in which a log is scanned to determine its size and shape, the resulting data are analyzed by a computer which deter-mines the optimum locations for cuts, and the proposed cut locations are displayed on the log optically for the operator's inspection.  If the operator overrides any of the proposed cuts, the computer recalculates any cuts not specified by the operator.  When all cuts have been approved, the log is kicked to a cutting bed, where the cuts are made by means of two independently controllable traveling saws.  The cutting bed is preferably defined by three sets of parallel plates.  The first set comprises stationary plates having V-shaped upper edges which define a V-shaped trough in which the log is initially received.  The second and third sets of plates are vertically movable and, when raised, together define a second V-shaped trough located above the first trough.  After the log is received in the first trough, the movable plates are raised to elevate the log to the second trough, where it is cut.  After each cut is made, the movable plates supporting the downstream side of the cut-off segment are lowered to allow the segment to roll onto an output conveyor, which carries it to the next work station.  In this manner the segments are automatically singulated without a separate singulating station.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to electronically control-led exhaust gas recirculation valves and more particularly to systems incorporating an electrical vacuum regulator.          The present invention provides an EGR system that is less susceptible to output flow changes caused by carbon build up.  The invention also provides a vacuum regulator that can be used with simple, low cost EGR valves.  Simple valves can be used by virture of the closed loop vacuum regulation feature of the present invention since the flow rate/vacuum signal relationship is not important.  A further object of the present invention is to provide an EGR flow regulation system which automatically compensates for pressure varia-tions which result in changes in the pressure differential across the EGR valve due to changes in exhaust system pres-sure and intake manifold pressure.

Abstract: Abstract of the Disclosure In a flexible circuit connector assembly a first circuit has exposed contacts which are positioned in register with the termination pads of another circuit by means of a connector which mechanically clamps the two circuits together. The connector includes a frame having an undersurface to which the first circuit is affixed.          Locating posts project from that surface and are received in locating apertures in the second circuit to properly position the connector and the attached circuit relative to the second circuit.  A generally c-shaped spring member engages around the frame with its arms extending beyond the locating posts and with its bridging segment extending more or less parallel to the frame reference surface.  An actuator mounted to the frame is movable between a releasing position wherein it deflects the spring bridging segment toward the frame reference surface to spread apart the arm hooks so that they are aligned with the locating posts, thereby permitting those posts to be inserted into the circuit apertures.  The actuator can also be moved from that position through an intermediate position which permits the spring to assume its relaxed condition whereupon the arm hooks draw together so that they engage under the circuit to a locking position wherein the actuator retracts the spring member and deflects its bridging segment upwardly away from the frame reference surface so that the arm hooks are urged toward one another and resiliently draw the connector tightly against the second circuit.
