Abstract: TIMING OF INTERNAL COMBUSTION ENGINE AS FUNCTION OF OPERATING PARAMETERS            (D#73,580-F) ABSTRACT OF THE DISCLOSURE          A control system controls the occurrence and the duration of time intervals during which sparks may be pro-vided in the cylinders of an internal combustion engine driving a crankshaft as a function of operating parameters of the engine.  Sensors sense parameters such as the vacuum in the carburator, the position of the throttle and the torque of the crankshaft and provide corresponding signals.          A distributor provides a pulse signal.  Each pulse in the pulse signal has a width corresponding to a predetermined rotational displacement of the crankshaft.  A counter with associated logic circuitry counts clock pulses in an up-direction during the occurrence of a pulse of the distri-butor pulse signal.  When the counter counts down to a particular count, a decoder triggers a one shot multivi-brator to provide a pulse, each pulse provided by the one shot multivibrator corresponds to the start of a spark time interval.  A preset circuit receives the sensed para-meter signals and presets the decoder so as to select the particular count to control the time of occurrence of the spark time intervals.  A second counter is loaded with clock pulses at a reduced rate, simultaneously with the loading of the first counter.  During the unloading of the first counter, the second counter is inactive.  However, the second counter is then unloaded at a faster rate when the I     spark time interval is started.  Upon reaching a zero count, a spark time interval is terminated.  An ignition system provides sparks to cylinders during each spark time interval.                             II

Abstract: OPERATING AND SPEED CONTROL MECHANISM FOR REVOLVING DOORS            Abstract of the Disclosure -An operating and speed control mechanism for revolving doors features an improved gearing arrangement which makes possible a gear ratio or reduction between the drive motor shaft and door shaft far greater than any gear reduction heretofore attainable, even when using a greater number of gears in the allotted space. Additionally, the improved gear transmission renders the mechanism even more compact than the most favorable prior art arrangements in the interest of satisfying more stringent architectural require-ments in the installation of revolving doors.  Unexpected benefits provided by the improved and simplified gearing are increased braking efficiency and extra braking force from a small centri-fugal brake assembly, and greater and more efficient lubricant circulation in the mechanism for the purposes of brake surface wetting and general lubrication and cooling of the mechanism.  A unique mechanism cover plate provides a magnetic flux return path allowing one-half of the permanent magnet motor to be eliminated and thereby rendering the mechanism further compact in its criti-cal vertical dimension.

Abstract: ABSTRACT OF THE DISCLOSURE          In the shaping of ductile metal sheet, especially superplastic alloy sheet, by the application of pressure differentials, the peripherally clamped sheet is first urged, by pressure differential in one direction, against a female molding surface to form a partially shaped bubble-like preform and then a male mold is advanced towards the sheet from the other side and a reverse pressure differential is applied to cause the pre-form to conform to the shape of that mold.  The active area forming the pre-form may be restricted by an apertured plate adjacent the clamping plane, matching the overall outline of the body, and a plate the other side matching closely the profile of the body may confine the action of the reverse pressure only to that part of the sheet that engages  the progressively increasing part of the male mold that extends through the clamping plane so that the sheet locks progressively onto the sides of the male mold to obtain an approximately uniform wall thickness in the finished body.

Abstract: PISTON FOR AN INTERNAL COMBUSTION ENGINE             ABSTRACT OF THE DISCLOSURE       This disclosure deals with a reciprocating piston for an internal combustion engine, particularly for a diesel engine.  The piston is made of a relatively high strength metal such as iron, and no more material is used than is necessary to withstand the thermal and mechanical loads encountered in use. A circular piston dome is supported by a support part which extends between the dome and a pair of piston pin bosses.  The bosses also support arcuate side thrust pads.  A ring hand is connected to the outer periphery of the dome by a con-necting part which is relatively thin and flexible.          The dome, the ring band and the support part are generally symmetrical about the axis of the piston.  The support part is annular in cross section and may be conical, cylindrical, or partly conical and partly cylindrical.

Abstract: CURVED-PATH BELT CONVEYOR                   ABSTRACT OF THE DISCLOSURE    An endless belt conveyor including straight path and curved path sections for the carrying and return runs of the belt.  The carrying and return runs of the belt are supported on a support frame by troughing and support idlers. In one version of the invention, the carrying and return runs of the belt are caused to follow a predetermined curve through the curved path section of the conveyor by powered edge drive rolls on the outside edges of the belt runs having a speed which is greater than the belt speed thereby causing the edge of the belt on the outside of the curve to be stretched relative to its condition in the straight path section.  In a second ver-sion of the invention edge drive rolls are also used on the edges of the belt runs at the inside of the  curve.  In the latter construction, the peripheral speed of the drive rolls at the inside of the curve is less than belt speed in the straight path section whereby the inner edge is compressed or stretched to a lesser extent than in the straight path section.  In the second version of the invention, the difference in peripheral speeds of the inside and outside edge rollers determines the curvature of the belt in the curved path section of the con-veyor.
