Abstract: ABSTRACT A facsimile recorder for marking an electrosensitive web with a remote scanner signal including a periodically interrupted framing signal and a video signal comprises a scanning electrode and a cooperative electrode for marking the signals on the web during successive scans across the web.  Scan-ning of the web is controlled by a framing circuit which compares the remote scanner framing signal with a recorder generated signal and uses the asyn-chronism of the two signals to control the scanning electrode until it frames the recorded scanner signal on the web.  The recorder pulse generator com-prises means sensing the voltage impressed through the web by the scanner signal.  When the scan completes its crossing of the web the voltage drop across the scanning electrodes increases producing a recorder pulse which is delayed and applied to the framing circuit.

Abstract: INTEGRAL PISTON & ADJUSTER FOR A BRAKE            ABSTRACT OF THE DISCLOSURE     An actuator mechanism for a brake having a plurality of friction disc compressed between a pressure plate and a backing plate.  The actuator mechanism has a piston located in a bore of a housing.  A pin fixed to the housing extends through and locates the piston in the bore.  A first tube located in the bore between the piston and the pressure plate transmits an operational input to the pressure plate upon closure of an air gap established by a spring caged on the first tube by a retainer.  A second movable tube connected to the pin engages the retainer member and holds the first tube away from the pressure plate to maintain the air gap between the first tube and the pressure plate.  The air gap forms a barrier to reduce the transfer of thermal energy between the plurality of friction disc and the actuator mechanism.  The piston, in response to an operational input, initially moves in the bore by overcoming the spring and brings the first tube into engagement with the pressure plate to eliminate the air gap.  At the same time, the piston engages the retainer member to establish a solid linkage between the piston and the second tube.  Further movement of the piston deforms the second tube and moves the second tube with respect to the pin.  Upon termination of the operational input, the second tube remains stationary and the spring moves the first tube to reestablish an air sap of substantially the same initial dimension after every brake application.

The digitized picture elements are then stored in a memory having a capacity equal to one full TV frame in accordance with the addresses assigned thereto.  Each video input may be positioned at any location in the composite output image.  Each video input may also be compressed in either the horizontal or vertical direction, or both, by means of hori-zontal or vertical compression factors which control the write address generating means so that certain picture elements of the video input are not stored in memory. A process of inter-polation is provided for the luminance component of the digi-tized picture elements so that the data values stored more closely approximate the values which the data would have at the points at which it is written.  A system of priorities is provided among the plurality of video input signals so that each desired input may be selected to occupy a portion of the composite output image to the exclusion of the others, even though they overlap.  The stored picture elements are read out of memory by means of a read address generator which is controlled by horizontal and vertical compression numbers so that a portion of the composite output image may be magnified to occupy the entire output screen.

Abstract: MACHINE FOR REDUCING LOGS                        ABSTRACT         A decortication or debasting machine receives raw uncut logs from a conveyor and reduces each raw log to a uniform reference cross-section along the length of the log and delivers the log to a conveyor which automatically feeds it onto a sawmill.  Cutting tools are swingable in planes which contain the rotational axis of the tool and the longitudinal axis of a log. the cutting tools and their driving motors are sup-ported by parallel guide rods each of which is pivoted about an axis that is perpendicular to the cutting tool's swing plane.  Hydraulic actuators, connected to the distal ends of the guide rods, cause them to pivot upon receipt of a signal from an electronic controller.  Sensing rollers acting through the electronic control maintain the speed of advance of the log through the machine relative to the depth of cut of the cutting tools.  Runners in contact with the finished surface of the log guide the cutting tools to maintain the uniformity of the finished log's cross-section.  Adjustable guides or springs limit the swinging motion of the cutting tools which in turn limit the depth of cut.

Abstract: ABSTRACT OF THE INVENTION      A uniform asphalt pavement structure of substantial area composed of aggregates of varying natural qualities produced by a controlled process including mix design, mix analysis, and plant control methods. The method uses a Riguez Index which is characteristic of the fine aggregate portion of the job mix formula, and flexibility/stability function derived from different combinations of crushed fine and blend sand. The Riguez Index is compared with volumetric representations of blended mixtures thereby to provide means for detecting voidage variations in the mixture resulting from natural changes in aggregate quality and to control a mixing plant for continuously producing uniform pavements. The job control method uses gradation over a single sieve size, asphalt quantity, and/or quantity mineral filler as job control parameters at the mixing plant to control voidage.
