Abstract: Abstract of the Invention A mechanism for inducing a crossing of one axis of a roll with respect to the axis of a second roll on a calender roll machine to correct for varying amounts of roll deflection under varying operating loads.          The mechanism includes a pair of biased levers which are pivoted on a frame diametrically across from one another against a bearing box on a calender roll. The roll has a mechanism at each end thereof. The levers are biased by incrementally movable pistons which when actuated, swing the respective ends of the calender roll in an arc about its mid-point to effectuate the controlled skewing of its axis with respect to the axis of a calender roll thereadjacent.

Abstract: Un ensemble régulateur de l'énergie circulant dans les méridiens du corps humain dans le sens d'une dispersion ou d'une tonification de cette énergie selon des troubles à traiter, qui utilise une onde émise par une diode émettrice. L'ensemble comprend deux appareils munis chacun d'une diode émettrice, et d'un circuit électrique pour délivrer des impulsions électriques à cette diode émettrice de sorte que celle-ci émet une onde intermittente. Les impulsions électriques sont d'amplitude substantiellement constante et sont délivrées à une fréquence parmi deux fréquences qui sont l'une par rapport à l'autre substantiellement dans un rapport de un à deux. L'une de ces deux fréquences est utilisée pour une dispersion de l'énergie tandis que l'autre est utilisée pour une tonification de cette énergie, ces deux fréquences ayant un caractère universel dans le sens où elles respectent la physiologie (très variée et complexe) de chacun des points d'acupuncture comme on peut l'obtenir avec les aiguilles, avec des résultats nettement supérieurs.

It has a flat bottom surface that pro-vides a level mating surface with that part of the vessel on which it sits.  Its top surface bears slots into which the carriage of the loader fits in a cross lap joint, interlocking manner.  The slots are located such that the loader dis-tributor is centered on the axial centerline of the reactor.

Abstract: ABSTRACT OF THE DISCLOSURE:       A hollow charge of a directed explosion effect, which charge comprises a mantel of the charge portion, an explosive material fitted inside the mantel, a detonator fitted at one end of the charge, and a metal cone fitted at the opposite end of the charge.  The mantel of the charge and the metal cone are precisely centered on a common symmetry axis on which the detonator is also positioned. The metal cone includes a concave globe face, wherein a detonation wave of the charge is spherical.  As viewed from a direction of an object to be blasted, the cone is shaped so as to define a convexity in the cone wall with respect to a wall of a straight cone of equal cone angle, the cone wall being of uniform thickness and the convexity being less than the thickness of the wall, so that when the hollow charge is exploded, a jet and a slug formed thereby obtain a velocity of about 2,500 to 3,500 meter per second when detonation velocity of the explosive is 7,000 to 8,000 meters per second.

Abstract: ABSTRACT         An electronic watthour meter for connection in a two-wire power distribution circuit comprises a shunt connected in one of the wires and an electronic circuit comprising a transconductance multiplier, a V to F converter and a reversible counter.  The DC power supply of the electronic circuit is referred to the wire containing the shunt, which wire is always live, so that the electronic circuit "floats" electrically on this live wire.  The first input of the multiplier can therefore be directly connected across the shunt, and the second input is connected via a high value resistance to the other wire so as to receive an input current representative of the voltage between the wires.  To eliminate the effects of drift in the mulitiplier, the polarity of the input current to the multiplier and the direction of counting of the counter are periodically and simultaneously reversed by a square wave signal of 1:1 mark space ratio.  The electronic circuit is implemented using LSI techniques.

Abstract: ABSTRACT OF INVENTION            An automatic irrigation control system provides the improvement in the prior art, which has previously set irrigation  time by a preset or predetermined amounts, by providing for feedback from the field by means of tensiometers or other types of sensors.  The tensiometers are made completely automatic and have a continuous analog signal output by the use of a backward gage pressure transducer.  The tensiometers also have remote refill capabilities so that they do not have to be manually filled.  Energy is saved by time sharing irrigation.  Water hammer is prevented by lagging the turn-off of the field which was previously being irrigated until turn-on of the next field.  Water ponding is prevented by providing time lag to allow water to penetrate the soil.

Abstract: ABSTRACT OF THE DISCLOSURE:                 A device for emptying a fluid from a pipe and for simultaneously filling the pipe with another fluid while preventing the fluids from mixing.  The device comprises: a support member having a head end for insertion in the pipe for emptying a fluid from the pipe, and a sealing means attached to the head end of the support so that when the device is inserted in the pipe the sealing means presses against the inner walls of the pipe thereby preventing the fluid being emptied from the pipe from mixing with the fluid filling the pipe.  A braking means is attached to said sup-port member for slowing the movement of the fluid filling the pipe thereby causing the pressure of the filling fluid to be greater than the pressure of the emptying fluid to produce a braking action that increases as the velocity of the filling fluid increases.

Abstract: ABSTRACT            A procedure and a device for attainment of an optimal degree of  compaction when compacting different material such as soil, asphalt and similar road construction materials with vibratory rollers. Normally, an increased vibration ampli-tude increases the compaction effect throughout the entire vibration frequency range. In any event, this applies in the beginning  of  the compaction work.  During  this  stage the vibrations  of  the  roller  drum  of  the  machine  can,  in principle,  be illustrated by a uniform sinusoidal curve.          When compaction approaches  the final  stage, however,  the roller drum tends to vibrate more or less irregularly in the form of cradle vibration or bouncing. If the amplitude is then reduced these phenomena can be avoided, resulting in an increase in the degree of compaction. The problem is solved according to the present invention by equipping the vibra-tory  roller  with  a  continuously  adjustable  eccentric element, two or more signal transmitters which are mounted axially separated inside the roller drum and which feel ten-dencies to bouncing or cradle vibration on the part of the drum,  and an electronic steering system connected to the signal transmitters which, via the resetting mechanism of the eccentric element, reduces the size of the the vibration amplitude as soon as irregular vibrations are imparted to the roller drum.
