Abstract: ABSTRACT  OF  THE  DISCLOSURE      An automatic toilet dispensing device for automatically discharging a measured amount of bleach (or detergent, or both) from a container which has an unobstructed opening in its top surface through which tank water can enter and form a reservoir of bleach solution; a venting means is located above the contain-er's top surface for venting air responsive to the intake of tank water through the opening, and for defining the measured amount; the venting means preferably being in the form of a bent tube having a relatively large diameter section adjacent the container's top surface and a distal section of smaller diameter; in operation the liquid solution in the reservoir above the block of bleach or the like rises in the larger diameter section of the venting means to a limited extent; however a water seal formed at the end of the smaller diameter section traps air, thereby preven-ting complete filling with liquid of the venting means; the measured amount of solution remains in the venting means until the water in the tank is lowered, the measured amount then falling so as to force out an equivalent amount through the intake opening and into the flush water.

Abstract: ABSTRACT OF THE DISCLOSURE         A modular and floatable offshore exploration and production platform system for use in shallow arctic waters is disclosed.  A concrete base member is floated to the exploration or production site, and ballasted into a predredged cavity.  The cavity and base are sized to provide a stable horizontal base 30 feet below the moan water/ice plane.  An exploration or production platform having a massive steel base is floated to the site and ballasted into position on the base.  Together, the platform, base and ballast provide a massive gravity structure that is capable of resisting large ice and wave forces that impinge on the structure.  The steel platform has a sloping hourglass profile to deflect horizontal ice loads vertically, and convert the horizontal load to a vertical tensile stress, which assists in breaking the ice as it advances toward the structure.

Abstract: A VIBRATORY SCREED INCLUDING A SPREADING   DEVICE FOR LEVELING AND DISTRIBUTING PLASTIC CONCRETE IN FRONT OF THE SCREED            ABSTRACT     A vibratory concrete screed includes a frame having first and second ends and a length equal to or greater than the width of plastic concrete to be finished.  A screed blade is coupled to the screed frame and engages the full width of the plastic con-crete.  Vibration generating structure is coupled to the screed for vibrating the screed blade.  A concrete spreading device is coupled to the screed frame to level the surface of the plastic concrete and to evenly distribute excess plastic concrete  in front of the screed blade.  The concrete spreading device includes a grading device having either an auger or a grading blade or both an auger and a grading blade.  A carriage maintains the grading device at a desired relative elevation to the screed blade and translates the grading device back and forth along the length of the screed frame.  The side to side translation of the grading device along the screed frame laterally distributes the excess concrete and displaces the concrete forward and away from the screed blade. Forward translation of the screed along the concrete forms together with the side to side translations of the carriage along the length of the screed frame levels and finishes the surface of the plastic concrete.

Abstract: TORQUE WRENCH   ABSTRACT            A torque wrench having a reaction bar and an arm extending laterally in the same direction from a work engaging head.  The arm is flexed in response to torque applied to the head through the bar and cooperable members on the bar and arm respectively engage as a consequence of that flexing.  The member on the bar is a pivoted lever which responds to the aforementioned engagement to swing towards a signal generating position at which it causes a switch to operate to close a circuit contained within a handle part of the bar. The circuit includes audible and visible signal means and those means are energized while the circuit remains closed. The switch is normally urged towards a circuit closed position but is prevented from reaching that position by a blocking member, and the aforementioned pivoted lever renders that blocking member inoperative when the pivoted lever is swung into its signal generating position.  Thus, the signals continue to be generated until the pivoted lever is moved back from the signal generating position.  Lost motion means functions to allow some relative movement between the pivoted lever and blocking member.

Abstract: A b s t r a c t A simple and fast process is described which serves to directly determine apurinic and apyrimidinic sites (AP sites) in DNA using [14C] methoxyamine which, after loss of a purine or pyrimidine base, respectively, reacts with the resultant alde-hyde groups of the deoxyribose groups.     The incorporation of the [14C] methoxyamine in DNA is propro-tional to the number of AP sites. Since methoxyamine does not cause the DNA to degrade, the unreacted AP sites can be mea-sured in order to determine the radioactivity of the acid-insoluble  fraction.     The process lends itself to the analysis of DNA-damages such as those which are physically or chemically produced. Moreover it is suitable to demonstrate and determine the activity of DNA glycosylases, in particular of uracil-DNA glycosylases.

Abstract: ABSTRACT    IMPROVEMENTS IN OR RELATING TO BUFFER CIRCUITS Signal distortion results from the difference between the low-to-high propagation delay and the high-to-low propagation delay through an individual buffer.  The present circuit includes two buffers (33, 36) having unknown distorting characteristics, arranged in series-inverting pairs (31, 33, 35, 36).  The first buffer (33) generates a predistorted signal (S3) from the signal to be translated (Si), with a delay at each transition due to either the high-to-low or low-to-high propagation delay of that buffer.  By inverting (35) and redistorting the predistorted signal through a second buffer (36), each transition in the output signal (SO) is further delayed by a propagation delay opposite in type to that experienced by that transition in the first buffer.  Each transition in the output signal has a total delay equal to the sum of the high-to-low propagation delay of one buffer plus the low-to-high propagation delay of the other buffer.  When both buffers are of the same type on the same integrated circuit, their distortion characteristics are equivalent, and each transition in the output signal is uniformly delayed so that the output signal is faithful in shape to the input signal.

Abstract: Abstract of the Disclosure The invention is directed to a saw chain for a motor-driven chain saw which includes cutting links, side connecting links, driving links and safety links.  Each safety link has an upper edge defining a wave-like contour that prevents chips from accumulating during the cutting action.          The cutting links and safety links of the saw chain are arranged with respect to each other so that overlap is avoided between the tail end of the rearward projection of the safety link and the forward projection of the depth limiter of the cutting tooth.  This affords the advantage that cutting chips do not become jammed therebetween.

Abstract: SENSING UNIT FOR ROW CROP HARVESTER GUIDANCE SYSTEM    Abstract of the Disclosure A sensing unit for a row crop harvester guidance system is attached to a row crop harvester header.  The header includes first and second crop dividers.  Each divider has a pair of sidewalls.  A crop receiving passageway is formed between the dividers.  The unit comprises a rotatably mounted crop engaging arm biased into a crop engaging position by a torsion spring. In the crop engaging position the arm projects outwardly from one sidewall of one of the dividers into the passageway.  The spring tension is adjustable to vary the amount of force required to actuate the crop engaging arm.  Variation in the force is desirable to permit the sensing unit to operate reliably in a variety of crop and field conditions.  Rotation of the crop engaging arm is limited by a shock absorbing guide movable in a slot in the sensing unit frame.  The sensing unit has a housing for shielding critical components mounted on the unit from exposure to dirt and debris.  The housing is readily removable from the confines of the divider to expose the components for servicing.
