Abstract: ABSTRACT OF THE DISCLOSURE A retroreflective relatively flexible laminate sheet construction has a thermoplastic web with a smooth light-receiving first side and a second side coextensive with said first side. A retroreflective pattern is formed on the second side. A slurry of granular material is deposited on the second side to cover selected portions of the formed pattern with remaining portions of the formed pattern devoid of the granular material, and said slurry is dried or cured to produce a well-defined pattern. A layer of backcoating material is deposited on the second side to overlay the granular material, the backcoating material contacting the thermoplastic web where no granular material has been deposited, thereby encapsulating the granular material between the second side and the backcoating layer. An added, outer layer provides additional weather protection for the thermoplastic web. Methods are detailed to manufacture the laminate, and compositions Or backcoating mixtures also are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE Printed products and their respective corres-ponding printing plates are divided into a plurality of image elements.  For each image element the surface coverage is determined by photoelectric measurements; a reference reflectance value is then calculated from these measurements, taking into consideration such parameters as the printing characteristic.  These reference reflectance values are compared with the actual reflectance values measured on the printed products and the results of the comparison are evaluated to from a quality measure and to calculate control values for the ink feed devices of the printing machine.  In this manner, the use of special color measuring strips may be eliminated.

Abstract: HIP, VALLEY AND JACK RAFTER       CUTTING APPARATUS       Abstract of the Disclosure -Compound angle saw cuts are made with precision on lumber components in the mass production of hip, valley and jack rafters. The required cuts are made by a power-driven circular saw blade which is caused to traverse a linear guideway in one direction with the saw blade in a first angular position to produce a first compound angle cut, followed by reverse traversing of the saw blade along the linear guideway while in a second angular position perpendicular to the first angular position to produce a second compound angle cut.  The saw blade, its linear guideway and operating elements are attached to a control arm forming a part of a pantograph linkage which can be driven around a sector gear having a protractor scale to establish the roof slope angle for which rafters are being cut.  The sector gear is adjustable on a primary support along a linear path to allow the axis of rotation of the control arm and saw blade to be located in a reference plane defined by the top surface of a lumber component conveyor. The axis of rotation is at all times perpendicular to the linear guideway axis.  The linear guideway and saw blade are also adjust-able on the control arm when the saw blade is at the mid position of its angular adjustment and in a plane parallel to said axis of rotation for making square cuts through lumber components so that one face of the saw blade can be placed precisely on the axis of rotation.  Lumber components are delivered in succession inter-mittently to a cutting station and are held at such station while the saw blade produces the compound angle cuts.

Abstract: ABSTRACT OF THE DISCLOSURE      For  diagnosing  bodily  functions  of a patient by analysing individual samples several blood samples are taken  from  the  patient  automatically  in  sequence  at predetermined   time   intervals,   collected   together separately   from  one   another,   retained  until  the completion of all the samples, and then analysed.   The blood samples are fed into a single collecting container one after another in time sequence with the aid of a control valve and are held separated from one another by the introduction of a separating medium between them or they  are  fed  individually  in  sequence  into  separate containers.  An anti-coagulant prevents the blood samples coagulating before analysis, and so the patient can wear the apparatus for taking the blood samples and can move about  and  behave  normally  throughout  the  sampling sequence.

Abstract: SINGLE LEVER CONTROL ARRANGEMENT                     Abstract of the Disclosure In a single lever control for the feeder conveyors of a combine harvester, movement of a manually operated lever directly actuates a drive train for driving the conveyors in a forward or normal operating direction. A second lever controls actuation of a drive train for driving the feeder conveyors in a reverse direction.  Movement of the second lever is responsive only to movement of the first through a cam slot and cam follower arranged so that selection of the drive for one direction automatically disengages the drive for the opposite direction.  A detent gate at the neutral position forces the operator to pause when passing through the neutral position, that is when disengaging one drive and engaging the other.

Abstract: CAPACITIVE ANGULAR POSITION TRANSDUCER     ABSTRACT OF THE DISCLOSURE       A transducer  for  sensing  the angular position of a shaft over a limited angle (e.g., ?30°) uses a printed cir-cuit board mounted perpendicular to the shaft between capa-citor plates of a bifurcated vane clamped to the shaft.  The board has two pairs of symmetrical  capacitor plates,  one pair on each side with each plate of a pair located symme-trically with respect to the midposition of the vane plates, and corresponding plates of each pair connected together at a junction to place the two corresponding variable capaci-tors in parallel.  Circuit means produces a Mark-Space sig-nal proportional  to the position of the bifurcated vane. Using the total Mark-Space period to continually derive a midposition reference, and comparing that midposition refer-ence to any deviation of equal Mark and Space periods pro-vides a position signal proportional to deviation from mid-position of the bifurcated vane.  By offsetting the midposi-tion reference signal, the position output signal will be proportional to the position of the plates of the bifurcated vane with respect to the circuit board plates from one ex-treme to the other.
