Abstract: ABSTRACT OF THE DISCLOSURE        A V belt pulley clutch assembly for a variable speed transmission which may be either the driving or the driven pulley, and which has one movable sheave which is both speed torque responsive, and wherein the torque responsive por-tions comprise raised spiral ramps on the hub of the movable portion of the V belt pulley driven through saddle type members riding on the spiral ribs. The ribs are spiraled axially along the hub of the movable portion of the V belt pulley in a direction so that when the driven member is subjected to more load the unit tends to shift into a lower drive ratio. That is when the drive clutch assembly is powered from a drive shaft, the spirals are arranged so that the pulley halves tend to separate under increasing load on the belt. The ribs are on the external sur-face of hub and can be die cast draft free for permitting driving and sliding between two relatively movable pulley halves.

Abstract: ABSTRACT OF THE DISCLOSURE           A control apparatus is disclosed for discriminating between light emitted from sources having respectively different flicker ratios (the ratio of the brightest and the dimmest intensities during a given period).  A photocell produces a voltage having a DC component proportional to the log of the average intensity of incident light and an AC component proportional to the log of the flicker ratio. After the DC component is removed, the AC component is amplified and may be applied to a filter-moving control means to cause appropriate color-correcting filters to be interposed between the scene and photosensitive material. as for instance in a camera.  Alternatively, the AC component may control a marking mechanism to encode the film with a mark readable during the subsequent printing process.

Abstract: ABSTRACT OF THE DISCLOSURE         A mechanism is disclosed for providing a lateral adjustment capability for anchors used to support engines or transmissions in dynamometer test stands or the like.  The mechanism is comprised of an arrangement  including a housing and a cylindrical slide member, adapted to be reciprocated in a laterally extending socket formed in the housing.  The position of the slide is adapted to be adjusted in the socket by virtue of a threaded engagement with a capscrew carried by the housing at one end of the socket, and is locked in any adjusted position by a pair of threaded bolts, passing through the slide and socket walls and which are advanced into one of the socket walls to squeeze together the corresponding surfaces of the socket and slide member.  The housing may be fastened to an anchoring de-vice or directly mounted to a base plate or other supporting surface.  The adjustment mechanisms are also disclosed as having the capability to be stacked to provide lateral adjustment in any lateral direction and are also disclosed as being utilized in opposing pairs in which case the slide member of one of the opposed pair is allowed to float to accommodate adjustments made in the other of the opposed pair to provide such lateral adjustment.

Abstract: ABSTRACT OF DISCLOSURE    This invention relates to aqueous solutions of cuprammonium carboxylate complexes and the use of such solutions as a fungicide for treating wood, painted surfaces, fabric and to inhibit algal growth.  The novelty of the invention resides in the compositions containing a relatively higher concentration of effective copper of between 4 and 10% for a considerably smaller concentration of water therein.  Aqueous solutions of such compounds have always been desirable because they are easier to apply on the substrate than solids and the production of these compositions in concentrated form has mitigated the problem of bulk handling.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to an improve-ment in a method for the thermoforming of containers from thermoplastic materials in which method the rim of the container is formed as an integral part of the pre-form from which the container is thermoformed.  The pre-form is obtained by introducing thermoplastic material into a closed space and then mechanically com-pressing the material.  The improvement of the present invention relates to improved uniformity of flow of the thermoplastic material into the closed space, the use of a closed space defined by surfaces having a surface roughness in the range 50-125 µm rms and to a modified sequence of steps for forming the pre-form in which the compression of the thermoplastic material is commenced prior to the completion of the introduction of the material into the closed space.  me process may be used in the manufacture of containers e.g. for the packaging of margarine, from polyethylene or polypropylene.

Abstract: MULTIPLE OCTAVE GENERATOR TUNING SYSTEM      ABSTRACT OF THE DISCLOSURE           Disclosed is a multiple octave generator system for providing tones in an electronic organ.  The system permits the production of both ensemble and celeste ef-fects by providing the appropriate amount of detuning between cascaded ranks of divide-by-two type tone genera-tors.  The generator system has a minimum number of adja-cent octaves that are locked and thus provides overall stretched tuning to more closely resemble pipe organ tuning.  An alternative embodiment of the generator system permits the beat rate of the lower octaves to be increased to a more desirable rate without causing the beat rate of the upper octaves to become too fast.
