Abstract: A drive-transmitting arrangement for use in a motor vehicle, fork-lifting truck or industrial machinery includes a differential or epicyclic gear assembly having an input member and two output members. One of the output members is connected, directly or indirectly, to the operating element of a hydraulic pump so as to drive the pump and the outlet line of the hydraulic pump contains a control valve which may be responsive to the parameters or an engine connected to the input member of the gear assembly. Adjustment of the setting of the valve means varies the resistance to movement of the pump operating element so as to vary the ratio of the gear assembly.

Abstract: TILLAGE APPARATUS HAVING IMPROVED CUTTING           AND DRIVE STRUCTURE    Abstract of the Disclosure An improved cutting and drive structure is disclosed that is particularly useful in conjunction with tilling apparatus for sod seeding purposes.  The structure includes a tillage blade or cutter wheel mounted for rotation by a drive structure that includes a rotatable drive shaft.  The cutter wheel has a thin disc-like body portion and a periphery with a plurality of teeth thereon, with different teeth being offset in opposite directions from the plane of the body portion.  The offset teeth which in a preferred embodiment have hard-facing on the cutting surface, have a specific configuration to allow the cutting wheel to produce a furrow in ground contacted by the wheel, with the furrow being wider than the body portion of the wheel due to the offset teeth, and this results in reduced soil compaction at the bottom of the furrow, as well as loose dirt therein to provide cover for seed deposited in the furrow.  The drive structure includes a friction drive plate for rotating the cutter wheel, with the cutter wheel being fastened to the threaded drive shaft so that the cutter wheel is self-tightening.

Abstract: CYLINDRICAL VARISTOR AND METHOD OF MAKING THE SAME           Abstract of the  Disclosure A varistor has a cylindrical core made of a sintered varistor material which includes a longitudinal opening between the core ends.  A pair of terminating layers are applied to the core, each adhering to one of the ends of the core and being in electrical contact with a lead wire inserted into the longtidinal opening.  An electrode film is applied to the outer longitudinal surface of the core with each end in communication with one of the terminating layers.  The electrode film is divided between the terminating layers into a pair of electrode portions by a gap which is dimensioned to predetermine the electrical properties of the varistor.  The preferred method of manu-facture involves forming a sintered, cylindrical core of varistor material with a longitudinal opening; applying a terminating layer to each end of the core; applying an electrode film to the core surface with each end of the core in contact with one of the terminating layers; dividing the film into a pair of electrode portions by forming a gap between the ends of the film; and inserting a lead wire into each end of the core opening in contact with one of the terminating layers.

Abstract: ABSTRACT OF THE DISCLOSURE         A bag having an end closure through which the bag is filled after sealing of the closure.  A valve sleeve is provided in the end closure through which a filling tube may be inserted for filling the bag.  After completion of the filling operation, the valve sleeve is tightly flattened within the closure, so that the material filling the bag does not leak through the sleeve.  The valve sleeve includes a flexible tubing secured to a reinforcing strip.  The reinforc-ing strip is secured to the end closure along substantially its entire length when the closure is sealed and prevents the flexible tubing from crimping, so that it may be tightly flattened.  A slit is provided in the valve sleeve from its inner end to about its middle along an axis parallel to the axis of insertion of the filling tube into the sleeve.  The means for securing the reinforcing strip to the end closure covers substantially the closure contacting face of the strip, except in the area of the slit.

Abstract: REFLECTIVE  LASER LINE GENERATOR            Abstract of the Disclosure Apparatus for reflectively generating a straight line light path from a laser beam comprises a planar re-flective surface which is arranged to reflect the laser output beam approximately 90°, and an arcuate reflective surface, such as a hollow cylinder, which is located rela-tive to the planar reflective surface such that the reflec-ted beam is impinged thereon normal to its axis of curva-ture.  The cylinder is arranged with its axis of curvature parallel to and offset from the laser output beam so that every increment of the columnar reflected beam strikes it at a point having a tangent which is at a different angle with respect to the reflected beam than every other incre-ment of the beam.  Accordingly, each increment of the beam is reflected from the arcuate reflective surface at a different angle, thereby creating a fan shaped pattern of light.  The planar mirror is angularly adjustable, for directing the reflected beam onto the arcuate reflective surface along a single circumferential line for making the resulting fan shaped beam straight and perpendicular to the axis of curvature of the cylinder.  Also, both the amount of offset and the angle of the axis of curvature of the cylinder are adjustable for adjusting respectively the included angle of the fan and its straightness and perpendicularity.

Abstract: OPTICAL PHASE MODULATION INSTRUMENTS     ABSTRACT OF THE DISCLOSURE    To obtain the refractive index of a fluid, each of two beams of light are transmitted at an angle through different ends of a  vibrating quartz crystal to phase modulate the beams of light with respect to each other and then transmitted through two different flow cells before being combined at a point of nearly equal optical path length from the source of light, with the resulting interference pattern being trans-mitted onto a photocell to generate an electrical signal which varies periodically with the modulation of the two beams of light.  The signal from the photocell and a signal representing the modulation of the crystal are compared in phase and a third signal indicates the refractive index of the effluent from the chromatographic column generated as a result of this comparison.

Abstract: ABSTRACT OF THE DISCLOSURE        Data information pieces are registered one by one in order to prepare its transfer to two computer parts which upon parallel-synchronous cooperation execute each one of two accordant instruction sequences. The execution of each instruction sequence is divided in numbered periods which owing to requested information transfers comprise each only one information transfer. The request for a trans-fer leads to a transfer number which is established by means of the period number obtained if the computer parts execute instructions belonging to corresponding periods, and by means of the higher of the two period numbers if the instructions executed at the same time do not belong to corresponding per-iods. A transfer signal is transmitted to one of the computer parts when the associated period number is equal to the trans-fer number. Due to a received transfer signal, the registered data information is transferred to the respective computer part. The accordance of both instruction sequences is maintained in spite of a time displacement between corresponding periods.

Abstract: ABSTRACT               The invention comprises an apparatus and method for automatically removing fat from a meat carcass.  A sensing station 10 (Figure 1) includes a row of needle probes 16 which can be in-serted into the carcass 30 and which produce an electric signal at a fat/lean interface.  The position of this interface relative to a support is recorded for each probe in a memory unit 18, and the carcass is then passed to a cutting section 11 where it is drawn over a knife blade 24.  The height of the knife blade is adjustable by a servo-motor 27 controlled from the memory unit, and as the carcass is pulled over the knife, information from the memory unit is progressively released to adjust the knife so that the cut through the carcass follows the-previously-sensed fat line.
